What to do if you're forced to marry a demon king's daughter in a horror game?

Are you sure you're taking something to help you sleep, and not some kind of drug that might enhance your libido?

Ah, of course, being a polite person, Su Yu wouldn't voice her complaints.

"This craft has been lost for a long time. I never expected you to have so much of it here."

The hostess looked at Su Yu with a complicated expression.

"To be honest, I think your asking price is a bit low now."

Su Yu: "Hmm..."

Yes!

I think so too!

So, should we discuss adding a pound or something?

Before Su Yu could even bring up the request for more weight, the male homeowner seemed to have read her mind and proactively offered, "We've always been reluctant to owe favors to others, so all the furniture, servants, and even the treasure vault downstairs are yours."

Su Yu was stunned for a moment.

Wait, a treasure vault?

"To be honest, we haven't opened or looked at that treasure vault either."

The hostess was quite honest and told Su Yu some news that really cheered her up.

"It is said that this is the treasure trove of the mermaid race..."

"However! As everyone knows, there are no mermaids on Neverland; it's just a widely circulated legend." The male host immediately picked up where the female host left off, correcting her in a very serious tone:

“I learned about the history of Neverland when I was in school. I think this must have been left behind by the first thieves to come to this island, and there should be a lot of surprises inside.”

Hearing him say that, Su Yu couldn't help but ask, "Then why did you leave it to me?"

The male homeowner chuckled twice.

"The door to that treasure vault is not something anyone can open."

"To put it in a more sci-fi way, it will choose its own owner."

"To put it more scientifically, it will choose the person whose genes are closest to its original owner to unlock the door."

As he said this, he habitually pushed up his glasses again.

"So, we're not actually sure if you can open that door..."

Su Yu nodded.

With this explanation, she could barely accept it.

"Then I shall respectfully comply."

Why would she refuse if there were more benefits to be had?

After dinner, the family asked Su Yu if they could stay another night and move out at dawn.

Su Yu readily agreed.

She wasn't sleepy at the moment, so she decided to check out the treasure vault located beneath the villa after dinner.

Of course, she had been paying attention to her surroundings the whole way here.

Only after confirming that no one was following her did she continue walking.

However, as soon as she stepped into the basement, a scene straight out of a horror movie unfolded—all the candles around the underground passage went out in an instant.

The narrow passageway can only accommodate one person at a time.

Su Yu subconsciously wanted to turn around, but heard heavy footsteps behind her.

Along with the footsteps came the sound of breathing, like a patient having an asthma attack, and the sound of chains dragging on the ground, scraping against the bluestone slabs...

"Damn it, it feels like I triggered some kind of instant-death flag!"

Su Yu immediately pulled out a hammer.

"There are still sunflowers in the backpack, but in this situation, turning on a light source would probably make things worse."

She is not a person without fear.

If a large group of ghostly figures suddenly appeared in front of her, she might actually be so frightened that her heart would stop.

With pursuers behind her, she had no choice but to keep going!

When she finally reached the entrance of the treasure vault, she saw a piece of clothing hanging on the door that looked very familiar to her.

"This...this isn't the clothing Xia Mai wore!"

Su Yu, who had already mentally accepted that she was the only player in this instance, felt a sinking feeling in her heart.

The clothes were stained with large patches of blood, and there was a horrific knife wound on the back of the clothes, from which the bloodstains spread.

"Xia Mai, is she... dead?"

This conclusion left Su Yu feeling completely bewildered.

"But when did she enter this place?!"

104. The Improper Maid, A Sleepless Night

Su Yu forced herself to calm down, walked over to the garment, picked it up, and stuffed it into her backpack.

Almost at the same moment she accepted the dress, the monster behind her seemed to disappear.

Su Yu felt a sense of relief.

"It seems the instant death flag has been lifted."

I opened my backpack and examined the garment closely.

At this moment, Su Yu noticed that it had actually displayed the item description.

"A blood-stained women's top: Does it look familiar? Maybe it's just your imagination."

Su Yu looked at the equally malicious item description and was speechless.

She decisively took out sunflower seeds from her backpack, planted them, and brought a ray of light to the small space.

At this moment, she was finally able to see clearly what was going on with the door in front of her.

To put it simply, this door resembles the entrance to a large tomb in the real world. It is made entirely of bluestone slabs, with bronze used as decoration on the edges, and is carved with a beautiful mural.

Su Yu couldn't quite understand what was written on the mural...

However, on the bronze-carved scallop, there is a clear hole that can be opened with a key.

She took out the mermaid treasure chest key she had obtained from the previous dungeon and tried to open the door.

"Ah, it really won't open."

The key is stuck inside and won't budge.

When Su Yu tried to take it back, she found it was even more stuck!

She froze for a moment.

While she was still in a daze, she felt the key gradually disappearing into the door, as if a force was pulling the key hard from the inside of the door.

"So, you dare to swallow my key, huh?!"

Enraged, Su Yu immediately increased her strength and pulled outwards with all her might!

The guy inside the door clearly hadn't expected Su Yu to have such strength, and couldn't win the struggle, so Su Yu forcibly took back the key.

"It's one thing to not be able to open the door, but to eat the key is going too far!"

Su Yu put the key back into her backpack.

Turn around and leave.

……

At this moment, Su Yu still didn't think there was anything wrong with what had just happened.

It was a bit strange, but not so strange that she couldn't understand it.

After all, strange things usually happen in treasure troves with legendary stories.

Let alone being chased by ghosts, even if Su Yu opened a door and saw a bunch of muscular men wearing only underwear flexing their muscles, she wouldn't think there was anything too wrong with it...

Now, she has returned the way she came and arrived at the second floor of the villa.

"Master, this way please."

A maid with wheat-colored skin, holding a candle, waited for Su Yu at the top of the stairs.

They changed their tune really quickly!

Only an hour has passed since we finished dinner!

Of course, now is not the time to complain about these things.

Su Yu is currently maintaining a contractual relationship with Doris. Otherwise, she might choose to renegotiate the contract with the maid to ensure that she would never betray her.

Without the power of words to bind her, she wouldn't often try to bind their relationship.

But now, things are indeed very different.

This is the inevitable result of increased power: the stronger one becomes, the lower one's sense of security becomes, and one may occasionally have the illusion that others want to harm them.

"Master, this is your room."

The maid opened the door with a key and respectfully invited Su Yu inside.

"Thank you."

Su Yu entered the room.

However, the maid lingered at the door, seemingly unwilling to leave.

"Is there anything else?" Su Yu couldn't help but ask.

"Master, would you like me to serve you tonight?" the maid asked in a very casual tone.

"...What service?"
