[Realistic experience]
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/fd56f8029cea1e66ae11b3f436f0031e378c7029.png)
Sitting in the simple and modern hall, I blinked at the poster that said “Immersive Pirate Game Experience” and looked at Lucien beside me.
MC: Did Professor Lucien specially chose a date place to “turn” into a pirate with me?
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/7e8720e569c2b989bb03969d87b7a80ee5b62df5.png)
Lucien: Sounds like MC isn’t too interested?
Lucien put the game brochure in his hand, pointing to the fun pirate villain pattern on the cover.
Lucien: I thought, you’d want to join me on a medieval treasure hunt.
MC: Of course I want to! I just didn’t think you’d be interested in this kind of immersive game.
MC: After all, most of the time, we go to see exhibitions or movies or something.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/00841f2e3b931486d25b894e63ca36488e2c0180.png)
Lucien: It makes me a little sad when MC says that, it sounds like my dates with you haven’t been anything new?
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/f442bf679f03b59e9f453d18616b41f3604fb509.png)
Lucien: Looks like I need to do some reflection.
He turned his head toward me, and a hint of grievance flashed in his deep eyes. I shook my head in a hurry.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/1e54dc8d84df7daca3efcd96bcb4e3c991ed99a1.png)
MC: Not really, I’m just a bit surprised.
He grabbed my wildly waved hand in amusement and gently squeezed it.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/da54785f9c955bc267e659b54f9dfe838d78081e.png)
Lucien: Instead of not interested, it’ s actually just a lack of suitable opportunities to try.
Lucien: It just so happens that this game company approached the Institute of Biosciences for professional consultation during the development stage
Lucien: In the process of understanding it, I found it interesting so I wanted to show it to you.
MC: Did the game company actually need to consult with the Bioscience Institute?
Lucien: Mmm. Most of the VR games on the market now are visually and auditorily realistic to a certain degree.
Lucien: But to achieve ‘total immersion’, you need the cooperation of neurons in the brain.
Lucien: In short, what we do is to help game companies “trick” the players.
Lucien: It makes them feel that they have really entered the medieval setting and that what they see and hear is really happening.
MC: I’m looking forward to it even more when you say that. It must be a very high-quality game for Professor Lucien to be the one who puts it through!
Just as I excitedly grabbed Lucien’s arm, a staff member came beside me.
Staff Member: Professor Lucien, the game pod is ready.
Staff Member: Our game is based on a medieval pirate treasure hunt. The following are the themed modules you can choose from. Do you have a favorite?
We bowed our heads and read the brochure carefully, and a moment later, a chuckle fell to my ears.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/da54785f9c955bc267e659b54f9dfe838d78081e.png)
Lucien: Since a young lady thinks our date is nothing new, why don’t we try this “creative” theme that focuses on “endless experience”?
I puffed up my cheeks when I heard his words, pretended to be angry and folded my arms.
MC: Although I totally disagree with the words of this observant gentleman…
MC: It sounds great, so let’s play this~
The staff member nodded and lifted his hand to show us the direction of the game pod.
Staff Member: The effect in the game is realistic and lifelike, but it is all virtual. Please don’t be too nervous and afraid. If you are not feeling well, you can give us signal in the game.
Without waiting for Lucien’s response, I stood up, cleared my throat and then extended a hand to Lucien.
MC: Professor Lucien can be rest assured that I have some experience in playing games. As a “senior”, I will protect you.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/4c0b946ff787bb7e09a57b284596d20bae4a13bd.png)
Lucien seemed to freeze for a moment, then smiled faintly at me, his face embedded in the brilliant sunlight from outside the window.
He lifted his hand and clasped my palm.
Lucien: Then I’m counting on you.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/6ee2bd43f4020549c1a2b72fdc5ed693ba0ad82c.png)
MC: Lucien, is that giant python real?
I huddled up against Lucien’s back, his intricately crafted medieval clothes tickling my face.
Lucien turned around and swept me into his arms, rubbing my back soothingly.
Lucien: Before entering the game, I remember a “senior” said that she would protect me well, but it turns out that it was just bravado?
MC: …I didn’t expect it to be so realistic! You didn’t see it, but the python just crawled against my foot!
MC: Seriously, why is there no a wooden sign here that warns us of the dangers!
Glancing at the misty town around me, I continued to hug Lucien tightly and gradually withdrew from the grass where the snake had just passed.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/a9c2d1262d95de7e687093e6eae34c414d825355.png)
Lucien: The reason it feels so real is because the machines attached to us transmit these sophisticated data to our brains. Then it performed an act of deception that went unnoticed by the brain.
It was hard for Lucien to move because I hugged him so tightly; his usual science lecture speech was accompanied by more than a few helpless laughs.
At that moment, the grass rustled again, causing my just raised head to be buried deep into his chest once again.
Lucien compliantly tightened his arm around me and rubbed my hair as he asked.
Lucien: I’m still waiting for MC to protect me, what should I do now…
MC: I… I can do it!
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/bd2823bb7bf4a548ffee7a499a5759658fc064a7.png)
MC: But only if you hold my hand tightly and don’t let go.
Lucien: Certainly.
Lucien: Even without this premise, I won’t ever let go of your hand.
Under the cold sky, several small huts stood side by side on both sides of the road.
There seems to be no one here, the place feels quiet. I can’t help but be a little puzzled.
MC: Lucien, what are we going to do next?
MC: If it’s like any other normal game flow, should we go looking for clues about the treasure?
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/bef542ed89f7d7c7151ec230db1953ecf5350bd1.png)
I turned my head and found Lucien’s gaze seemed to stop in one place, so I followed his line of sight-
There is a large bulletin board not far ahead, which is particularly conspicuous in the quiet town. It seems like a kind of hint.
Lucien squeezed my hand and gave me his usual lighthearted smile.
Lucien: Well, I think there may be an answer for us there.
[Old Friend]
MC: Looks like it’s all about pirates.
MC: Weird, is there no reliable information about the treasure?
Lucien: And what should we do at a such time according to the experience of my “senior”?
MC: Hmmm… Then we should look for any NPCs.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/37cae68ede91e338d53a306996c369e5dd4cd27c.png)
MC: Lucien look, there seems to be a person standing over there
Lucien: It’s strange that I didn’t notice anyone there before.
Lucien: Anyway, let’s go over there first. Maybe he will tell us useful information.
When I got closer, I realized that the NPC looked like Pete.
MC: Do you recognize us?
Pete: As expected, you two really went looking for the treasure that can causes amnesia…
MC: The what…? Lucien, can you understand what he’s saying?
Lucien: I think this ‘Pete’ is not the same Pete that we know.
Lucien: Hello, do you know who we were?
Lucien: And what is it about the treasure you just said that makes people lose their memories?
Pete: The rule in this town is that if you want to inquire about something you have to pay for it.
MC: Is it meant to be a gratuity? But we don’t have any money…
Pete: I heard that the owner of the blacksmith store is recruiting people to do odd jobs…
Pete: You guys can check it out and you should be able to get some pay.
[Successful intel]
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/894f6e3ad5228986ca87f7d0a0e6cee3b5a1f373.png)
Lucien: I think these should be enough to pay for the answers we want.
Pete: Absolutely!
MC: …I didn’t expect Pete to be so money-oriented.
Pete: I used to meet you in pairs, you two were pirates who often go out to sea.
Pete: Although I’m not familiar enough to know your names, I can see that you both cherish each other.
Pete: It is said that if you return to the place where you have lost your memory, that is where the treasure is located.
Pete: -And then you can get your memory and identity back.
MC: But where’s the treasure?
Pete: I’m not sure about this one. But you guys said you were going to the forest before you left.
Lucien: It seems that our next destination is clear.
Pete: By the way, there is a lack of clean water in the forest, so don’t forget to bring a water bottle.
Pete: You guys go look in the store, there should be one in that place.
MC: But all the money we make goes to you…
Pete: This money has always belonged to me, the old blacksmith robbed it from me by ‘winning’ a bet. And now it just returned to its rightful owner!
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/015cbaba6c6bd64638d4cdc1e0584b5386234125.png)
Lucien: Regardless of the veracity of your bet.
Lucien: The money is still the legal payment we get from the old blacksmith for our labor.
Pete: …Okay! You guys can take it back.
- They get the water bottle by buying it in the store.
[Preparatory boarding]
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/b44bc34e220e3ff73885dfe78083082e137259d3.png)
MC: There is only one boat here, and I don’t know if the captain will take us to the forest.
MC: Lucien, do we have any money left to buy the ship tickets?
Lucien: All the money basically went to Pete and the merchant who sold the kettle.
MC: How about we go back to work for the blacksmith store owner?
Lucien: There’s probably no need to go to all that trouble.
Lucien: Since the game setting is that we had gone together to find the treasure, it means that the only ship in the port is ours.
Lucien: I believe our ship is the one in front of us.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/7e5122c3c297481102b8d3617bf66d3c16148952.png)
Lucien: Come aboard, my little explorer.
[Set Sail]
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/12cd64e066ad735405bec3de520f7260ebf6fa7e.png)
MC: Lucien, do you know how to steer this pirate ship?
Lucien: Although I don’t know it in real life, I think the way to drive a ship in the game will be special.
MC: The boat is moving!
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/78d33ebce045f7513dde1e7050b863620a8db042.png)
Lucien: There is also a map with the location of the forest and other places marked on it.
Lucien: It seems that the “we” before the amnesia had made perfect preparations.
[Who is speaking?]
MC: Isn’t this forest too big? Can we really find the treasure here?
Lucien: Rest assured, from the perspective of the game company, they must have estimated the time for players to pass the level in advance.
Lucien: So there will be an NPC or something to guide us.
Lucien: Come on, let’s get off the boat first.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/ec29cc2f2c83dcbd4d74754d1d08a511f3739d2b.png)
Big Tree: Hello there, young passers-by.
Lucien: Hi, we’d like to inquire about something.
Big Tree: You guys are in luck, I’m an all-knowing, all-seeing tree.
MC: Really?
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/1f477c2ca67ca07c9c57da616450103aeb80e8f9.png)
Lucien: Do you know our name?
Big Tree: A name is just a moniker; there can be countless identities, and the only thing that you know is that you’re changing.
Big Tree: No matter what your name is, you will always be you
MC: There is a feeling of “listening to your speech is like listening to your words”…
- It literally means that if you hear someone say something, you are really just listening to a word without getting any useful information. Its English equivalent is probably every 60
seconds in Africa one minute passed lol.
[The envy of the big tree]
Big Tree: What do you think the other person was like before amnesia?
MC: Lucien is so smart, so he must be an expert in astronomy and geography-
MC: The great scholar who has all of the knowledge!
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/625a7116006c5bfabf0c6dee12fb18acf6cb0dd7.png)
Lucien: For me, MC is MC.
Lucien: No matter what her previous identity was, her present self is what I like the best.
Big Tree: (-_-)
Big Tree: So what do you think your relationship is?
MC: It is the most important and irreplaceable…
Lucien: That’s my answer as well.
Big Tree: …Okay, okay, I get it. If there is no problem, just hurry up and go.
Big Tree: No.
Big Tree: To find out where you’ll have to prove that you’re as smart as she says you are.
Big Tree: If you can find the thorn fruit, I will tell you a clue to the treasure.
[Thorn fruit?]
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/8d4501655d8444aa617f174f409b46790c144671.png)
MC: Wow what a cute kitty!
Lucien: She seems to be glowing and doesn’t look like an ordinary kitty.
MC: She’s an elf!
MC: Excuse me, can I have a moment of your time?
Elf: Can you?
MC: Huh? You’re asking me?
Elf: What do you think?
MC: …Lucien, it’s better for you to be the one who communicates.
Lucien: Hello, can you tell us where we can find the thorn fruit?
Elf: All right, handsome guy.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/f5d79b7a5db94321a83a98a311e1a82019b0d7d5.png)
MC: ….
Elf: I happen to have thorn fruit, if you are willing to exchange 5 fabrics with me, I will give it to you.
MC: Excuse me, we have 5 fabrics, can we still trade with the fruit now?
Elf: Can you?
MC: …Lucien, it’s better for you to do the communication.
Lucien: Hello, there are 5 fabrics for you, can you give us the thorn fruit?
Elf: Hee hee a handsome man, just take the fruit away, I will go to the town tailor store to customize small clothes.
MC: Is this considered as cheating?
Lucien: The big tree did not say anything about rules, so all available means are not cheating.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/3f60f6e8797c959d40e3cdde26c7751db104aa8b.png)
Big Tree: It seems that you are indeed a little clever. Let me tell you, the clue to the treasure is in the cave.
Big Tree: The location of the cave is marked on the tattered parchment scroll wishing you luck.
MC: …
Big Tree: Where can I get the tattered parchment scroll, you ask?
Big Tree: Some time ago it fell into the hands of humans, should be a fabric seller, I can only help you this far.
- They buy it from cloth merchants.
Big Tree: Have you already got the tattered parchment scroll? Look, the location of the cave is already marked on the parchment scroll.
MC: Yeah!
Lucien: Then let’s get going.
[The next stop]
MC: Lucien, did you hear any strange noises?
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/ec1935695239800d473a0ce599829a28fcefa164.png)
Lucien: I think, this time it should not be ground python.
Lucien: But maybe it’s something like…
MC: Ahhhhh stop it! Hurry! Let’s get off the boat!
Lucien: <( ◜‿◝ )>
[Free Trade]
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/f77992d297ba84c57c9f6684c7f55cd2fe46fd3e.png)
Take a closer look at torn and tattered mural paintings.
Lucien: The mural seems to say that to find the treasure, you need the guidance of a school of fish.
Lucien: And the fish are typically somewhere in the sea near a deserted island.
Lucien: It needs to be found in a special way.
MC: Then what? Hey, why is the most critical location there is missing?
Lucien: It seems that finding the missing mural is our next task.
MC: Huh? There are so many bats here, could they hiding it here?
Lucien: MC’s hypothesis sounds inexplicably plausible.
MC: There are also a lot of bats here, maybe it’s hiding here.
MC: Ah! Something has fallen!
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/c44f06160a3265eec2962a586ada76dfa8cf439b.png)
Lucien: It looks like a compass and there seems to be a small treasure map inside.
MC: Why would they place the treasure map here? Are they afraid of it being stolen?
Lucien: Probably because it is easier to conceal what is to be hidden by making it part of the item.
–clunk!!!! There was a strange sound.
Lucien: It seems that there are other people besides us who are interested in this mural.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/184653333ad9a51ce999a8dfa9f361037c5f19f3.png)
Merchant: It’s unfortunate that you guys ran into me today.
Merchant: I heard your conversation just now, and what you want is hidden in one of my goods.
Merchant: But I will not tell you, you have to choose for yourselves.
MC: Lucien, what do you think? Which item will it be hidden in?
Lucien: This sculpture of a bunny reading a book may contain the fragment we are looking for.
Lucien: Just like the treasure map just now, people in this era know how to hide things very well.
MC: Then we’ll buy this!
Merchant: Nice eye.
Merchant: The engraved fragment is yours, go and use it where it’s supposed to be.
MC: The book in the bunny’s hand is the carved fragment! Lucien, you are amazing.
Lucien: Because there is a person who looks a lot like a bunny, I instantly saw it at a glance.
[Look at the picture and talk]
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/5f92b50d166e8634d10dccf93a73b452ae3b38f9.png)
MC: The first image looks like a pile of rocks.
MC: This stone seems to refract light and reflect it into the sea…
Lucien: Then, these fish under the sea should be attracted by the light.
MC: That’s right! The second image makes it clear that it’s a shipwreck.
MC: The third shining image should be the treasure we are looking for!
Lucien: In other words, this treasure is in a shipwreck at the bottom of the sea.
Lucien: To find the wreck, you have to find these small rocks on the deserted island first.
MC: The little rocks will attract schools of fish, which will then lead us to the wreck! So exciting!。
Lucien: This little student, she must have been good at reading and telling stories as a child.
MC: Of course, I will let Professor Lucien know more about it when I have the chance.
MC: Lucien! The skeletons here seem to have lit up for a moment!
Lucien: It seems that this cave riddle solving is not over yet.
[Guiding rocks]
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/177fec167369e1868cde7d25ca6a4113e5e29d45.png)
Lucien: Any findings?
MC: Lucien, there seems to be some small stones in it.
MC: Don’t you think that if we put them up, they will look a lot like the ones in the mural?
Lucien: It is indeed the same… I understand.
Lucien: It looks like we’ll be taking these guiding rocks with us on our journey to the deserted island.
Lucien: It’s a good thing you were attentive, or we might have missed them.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/8cd4f566e956dd65740d0d64d3f9c85e6c9c0a08.png)
MC: It’s all because Professor Lucien has taught me well.
[Brave the deserted island]
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/29adf79714be07f0c1d22ec6f8f86f9dec1f0757.png)
MC: Let’s go and put the guide rocks on the island!
Lucien: Have you figured out where to put the rocks?
MC: Eh? We need to look for a specific place?
Lucien: I began to wonder if MC really is the “senior” here.
[Roadblocks]
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/343f9c01ee68be6c90b137aa0d270c2879fdb0cc.png)
Native: ¥….. &¥## ….. %%&
MC: Hello! Do you know where to place the guiding rocks? You…
Native A: Grrr, %@! #, haven’t seen a living person in a long time!
Native A: If you don’t want to become my ration, give 20,000 gold coins in exchange of your life %…@! #!
MC: You want to eat us?!
MC: You can have all the money! You just have to keep your word.
Native A: Ahoy, ahoy, a fortune!
Native A: But I only promised only I would not eat you guys, not others people, you guys take care of yourselves hahaha.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/08af0bfd431cd3ffeb94766462e815fa63289c8a.png)
Native B: What a handsome young man and beautiful woman, you two look so delicious. #¥…
Lucien: Did you know? All food is organic and inorganic matter from nature.
Lucien: And you are also one of the substances, converting one substance into another…
Lucien: There is no point in doing anything but wasting energy.
Lucien: That is to say, the act of eating does not make any sense.
MC: Good job Lucien! Make him dizzy~
Native B: I can’ t understand what you are saying! &¥%^
MC: Did you just knock him out???
Lucien: Sometimes a rough solution is simpler than a smart solution.
Lucien: This is not a place to stay for long, we may need to avoid the natives first before seeking treasure.
MC: Let’s go to the other side and check it out!
[Avoid Natives]
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/f7ff2f61eff5c5871648b5bbb87b491a4562c0ad.png)
MC: For the time being, we have escaped the natives, but it is still dangerous.
Lucien: There is a broken boat over there, why don’t we go over there and hide.
MC: Mmm!
MC: Lucien, did you hear a strange sound?
Lucien: It should be the sound of airflow flowing through the cave.
Lucien: But this is the game world after all, there may be unexpected “surprises”-
MC: QAQ Don’t scare me.
Lucien: Want to hold my hand? Maybe by letting you feel me by your side, you can be brave enough to explore.
MC: Indeed, it was a refreshing experience to see the dusty Professor Lucien.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/abfb92786a811732111c299ae5e0a7985cce8ed7.png)
Lucien: It is also a rare experience to experience a “dusty” treasure hunt with you.
MC: Then I will document such experiences well!
MC: Huh? Look! is there another exit over here?
Lucien: Well, judging the wind and the light it does seem to lead to another place.
Lucien: Want to check it out?
[Master of the Sea]
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/6f645d76c18b33d64666fb82c9ab6fec8263e138.png)
MC: Look! There are sunlit rocks along the coast, so beautiful.
Lucien: Maybe this is the place we’re looking for.
Lucien: Want to try putting the guide rocks on it?
MC: Mmm!
I put the guiding rocks and the sunlight refracted in a peculiar way.
MC: Wow, there is really a light shining on the sea.
Lucien: The sea where the light spot is located should be the location of the mysterious school of fish, let’s go check it out.
MC: Are we going to dive?
Lucien: That’s a good idea.
Lucien: If there are amazing sea creatures in this world, we are just in time to feast our eyes on them.
MC: Does Professor Lucien also have imagination about the underwater world?
Lucien: Rather, I want to see the underwater world that she imagines in her mind.
Lucien: It must be much more beautiful than I can imagine.
[Cannon, open fire!]

MC: Look! that glowing area must be where the treasure is!
Lucien: The light represents the treasure, which is similar to the painting on the mural.
MC: Eh? Do we need to find a specific place again?
Sea Monster: Hold on, this little boat ahead.
Sea Monster: This tree is planted by me and so road is mine, if you want to cross this road-
Sea Monster: Hand over the treasure!
MC: Wait, how did you plant a tree here?
- Then we play a mini-game where we shoot octopus with cannon

MC: Finally, we knock them out. Are you hurt?
Lucien: Of course not, we worked perfectly together.
Lucien: I can see that this lady sailor already has the spirit of riding the waves.
MC: Back to the topic, how should we dive down?
Lucien: There seemed to be fishing boats on the shore of the small island, let’s go over and ask them.
[Gift of Love]

Fisherman: Shipwreck at the bottom of the sea? My fishing boat can help you tow the shipwreck, but you have got to do me a favor.
Fisherman: Girls nowadays like shell bracelet, and my granddaughter wants it too. Can you make one for me?
MC: Of course it’s fine!
MC: These little shells are so cute, they will definitely make a bracelet that will make his granddaughter happy.
MC: Huh? Why did you pick up so many shells?
Lucien: The fisherman said that shell bracelets are popular now, and so my little girl should have one too.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/273d59f752a1d8d93415b20917f60d7342358896.png)
Peddler: I never thought there would be customers in such a desolate place. I am a merchant, would you like to see my goods?
Peddler: If you want a shell bracelet, just bring 5 shells to me and I can help you make it.
Peddler: This bracelet is now popular, so the production cost is very low, just take this bracelet as a meeting gift.
Fisherman: The aesthetic of young people is still good.
Fisherman: According to the agreement, I will help you to drag the sunken ship up. Let’s meet on the other side of the island
MC: Thank you so much!
[Treasure Key]

Lucien: The light is emanating from behind a dark door inside the ship, so the treasure we are looking for should be right here.
MC: But the door seems to be locked, we have to find out if there is a key.
MC: Lucien, look at this beautiful coral.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/6a188b5c9620af4007be254875e483465c867ebe.png)
Lucien: Indeed, it looks like flower from the sea.
Lucien: However, the one in the middle has a strange color.
MC: Let’s see… it seems to be hollow.
MC: Found it! Here is the key to the treasure!
[Glorious Ball]
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/c8385e397d83fae3a9252d4a8a9800d0b0af1e79.png)
Click-
The door crack spreads thick floating dust, the key in my hand instantly turned into a wisp of smoke, and the ship’s door automatically popped open.
There was no expected golden treasure, behind the door of the ship was a mist, and there seemed to be nothing.
MC: How can this be…
MC: Lucien, are we experiencing a bug in the system?
Lucien: If it’s a bug in the system, an alert should pop up soon.
Lucien: So we might as well wait a bit.
Right after he spoke, a slender light appeared out of thin air, which was woven and extended as if it were alive.
Finally, a looming human figure is constructed, and the glittering light is scattered around its body.
MC: But there is nothing here… Who are you and what is this place?
I was a little puzzled but seemed to understand something else. This virtual figure is probably some kind of NPC.
I couldn’t help but look at Lucien in confusion, just in time to meet his bemused gaze.
Lucien: MC, where do you think this room is located on this shipwreck?
I was stunned and glanced around the spacious area.
MC: The place looks so spacious, maybe it was a ballroom before?
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/7407ffbf44170f9798340ff9cee0d542e56851f3.png)
As soon as the words were said, the glowing light on the NPC disappeared after two flashes.
The depths of the mists also began to emit a hazy, colored glow.
Soon, the increasingly bright and dazzling colors gradually revealed the details.
A crystal chandelier flickered on the golden wall, reflecting strands of soft light on the velvet window curtain embroidered with silver thread.
At a glance, it looks like a glorious ballroom!
MC: Lucien, what’s going on here?
Lucien: Remember when you first pointed to an NPC and said he looked like Pete?
MC: I remember, when we walked past him, he said he was Pete, and it took me by surprise.
Lucien: In fact, from that time I vaguely feel that something is not right, so I have a conjecture.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/0779a90daba12942ec0c49ddee692ea0a39384e1.png)
Lucien: Perhaps our ideas can change the environment here…
He suddenly paused and shook his head with a faint smile.
Lucien: No, it’s not so much about change as it is about creation.
Lucien: It’s like when we head to town, where there was nothing, but it slowly becomes lush…
Lucien: I think it’s because the system picked up some of the information from our profiles and conversations, and then created the game content accordingly.
I blinked, thinking over his hypothesis.
MC: Wow, so amazing… But why would the system do that?
Lucien: Perhaps because this treasure wants to give us the appropriate hints from the very beginning.
Lucien: MC, is there anything else you want to do, but it’s hard to realize in real life?
Lucien: I think now is a great opportunity.
I vaguely caught the meaning of Lucien’s words, looked around at the glittering ballroom, and smiled.
MC: Well… I want to participate in a real banquet with Professor Lucien on this kind of medieval ship!
As soon as the words left my mouth, the ballroom in front of me was once again enveloped in light.
When I opened my eyes again, I was greeted by a magnificently dressed crowd.
They twirled gracefully under the crystal lights and their gorgeous skirts blossomed into layers of petals on the carpet.
MC: Lucien, it really happened…!
MC: But it feels a bit monotonous, there should also be music to it.
Before the words left my mouth, a long, elegant melody flowed over the ballroom. I looked at Lucien with delight and swung his hand.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/74a7eb4237ced951aff3c87c2dc350d177290cd9.png)
MC: Lucien, try it too.
Lucien: Although my imagination is not as rich as yours… I do want to give it a try.
Lucien: After all, the opportunity to do as you wish like now is indeed rare.
He leaned over slightly with a smile in his eyes and held out his hand to me.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/b237c83de799f041f175955c0bc0f148a6b28fae.png)
Lucien: This beautiful lady, please dance with me above the rolling waves.
The stable floor tilted up in response to his voice, and just as I was slipping back, Lucien wrapped one hand around my waist and held my palm in the other, stepping in the dance.
Lucien: I also want you to see this era in all its rightful glory.
The glazed windows creaked open. Ships with high sails passed outside, and the sailors on board were busy carrying the goods.
One of the captain-like men blew the trumpet in his hand, and the loud trumpet sounds rippled back and forth on the sea.
MC: Lucien, this should be one of the most special dance we have ever done, right?
Lucien: Definitely. But I want to be a little more special.
Lucien: Because, I want MC to remember this moment forever.
As his words fell, only Lucien and I were left in the dazzling ballroom.
We continued to twirl, stepping around in circles on the soft carpet.
I stared at him intently until the end of a dance song, Lucien’s footsteps gently paused and he leaned down towards me.
Lucien: Before this dance is over, I would like to ask MC for the treasure that belongs only to me.
Lucien: May I?
MC: You may.

I closed my eyes and smiled to welcome the warm and familiar sweetness.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/dfd2d70463196900e868a7d1c2289ff627570bd9.png)
When I open my eyes again, the pod door in front of me has slowly opened
I stood up and took two quick steps, smiling and hugging Lucien who was already out of the cabin.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/77c812acc72a4672bd8f3bc5870386aff87cf1c0.png)
MC: Lucien, I didn’t expect this game to be so interesting, the environment and background inside can actually be created by the players themselves!
Lucien: I think it is because the endless creativity of the human brain that makes this game extra fun.
Lucien: But even so, our brains need to be constantly stimulated in order to be more creative.
A staff member walked up to us and handed us a photo in his hand.
Staff: Professor Lucien, Miss MC, congratulations on your successful completion. This is your wonderful moment in the treasure hunt.
Staff: We’re so happy to see your creativity and hope you’ve had fun in the process!
In the quick photograph print, Lucien is holding my hand. We’re dancing among a gorgeous and lavish light.
When the staff left, I tilted my head, looked at Lucien, and spoke in a serious manner.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/15ced0e7420094d677fa6a889afc0da48c60c5c6.png)
MC: It was thanks to Professor Lucien’s creativity that I was able to experience such fresh and unforgettable experience.
Lucien: Is that so? But my idea is just an extension of your idea.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/3bfa3ff4b7742f54bd11c9aea6fed10c59b48d78.png)
Lucien: So without you, I probably wouldn’t have been able to think of anything.
His tone had a familiar “aggravation” that made me laugh.
MC: Hmm, liar~
The aggrieved look between his eyebrows was even greater, he even sighed innocently.
Lucien: This is so wrong to me.
Lucien: Every word I say comes from my heart.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/a45391c17ad45c15a0e3012cfe043ab7419e34aa.png)
Lucien: Well anyway, remember what I just said, stimulation is essential if you want to be more creative.
MC: Do you mean that I can stimulate Professor Lucien’s creativity?
Lucien: More than creativity, to be precise.
He lowered his eyes, his eyes traveling slowly over me.
Lucien: My life is like an open book when I am with MC.
Lucien: It can be filled with all kinds of answers, or it can be left blank.
Lucien: You are the one who showed me that everything in life is undefined and creates a myriad of possibilities.
His voice was soft and gentle. The moment it fell I can feel it circling on my heart.
MC: Oh…
I laughed heartily and stepped forward to clasp his hand, trying to hide my pounding heart.
MC: Since I received such a high evaluation from Professor Lucien…
MC: Then I’ll have to bring more undefined creation to your life in the future!
Lucien: Then I’ll keep my expectations up from now on.
Lucien: Because I was also curious, with such excitement and influence…
Lucien: What kind of “world” can I create for MC.
![[TL] Sunken Treasure - Main Quest Translation (Lucien) image](https://xumoarchive.com/wp-content/uploads/2026/01/a45391c17ad45c15a0e3012cfe043ab7419e34aa.png)
Lucien: This may be a proposition that needs to be answered slowly over time in the future.
