The envelope was made of yellow paper, with a hard texture and a faint scent of lemon.

The opening of the envelope was sealed with red sealing wax. After carefully removing the wax, a folded letter fell out.

The letter paper was softer than the envelope, and its material was indiscernible.

The handwriting on it was messy and illegible,

with many dried water stains and smudges.

The letter read as follows:

"Hello, Morgan.

By the time you read this letter, you will have already installed the battery, searched the house, and feel very confused about your current situation.

You are panicked, desperate, and helpless,

unable to remember who you are or where you are, possessing nothing but a cage-like rubber suit.

Although this may seem cruel to someone who has lost their memory, the current situation is what you deserve—you are a greedy, cowardly, numb, despicable, insidious, selfish, and irresponsible little man who only thinks about running away from problems.

Perhaps only in this way can you awaken some semblance of conscience.

Your ultimate goal is to leave here.

That glass battery can provide you with three hours of energy for action.

If you exert yourself vigorously, it will drain even faster—you need to pay attention to the remaining solution in the battery at all times. When it runs out, that is when you will die.

Unless you can find some kind of 'raw material' to restart this machine....

Unfortunately, I cannot give you any more hints.

The thought of you looking at this letter at this very moment, using your clumsy brain to ponder what I have written,

makes me feel uncomfortable.

In any case, good luck."

Li Ang frowned as he held the letter, glancing at the glass battery on his left shoulder.

The level of the transparent liquid inside the cylinder had dropped slightly, by about one-eighteenth.

"Starting from when I installed the battery, I've been in this room for about ten minutes, which means I have two hours and fifty minutes left."

Li Ang said, "Assuming the contents of the letter are true, then I, or rather 'Morgan,'

am trapped here because of something—there could be many reasons,

such as sleeping with someone else's wife,

sleeping with someone else's husband,

or simply being morally bankrupt, attracting righteous people to knock me unconscious, erase my memory, and lock me in here.

Like in *Saw*."

He scanned the room again. "If the person administering this private punishment has a great feud with Morgan,

and he (possibly an alchemist) has the technical ability to brainwash,

and create a huge space—the first stage task description is to leave Room A, which is enough to prove that the cage is more than just this small room.

Then, could Morgan have been repeating this escape game?

No matter how many times he completes it, he will be knocked unconscious by the fully-powered vigilante at the last moment before escaping,

then have his memory erased, be moved back here, and wait to wake up and do it all over again, endlessly, without end,

to enjoy the pleasure of revenge."

Trapping an enemy in a cyclical cage, preventing them from ever reaching the truth of death,

is indeed a good idea,

but it's not so fun when the target is oneself.

"There are no drag marks on the ceramic floor, and the bed is neat and tidy, without bloodstains or other bodily fluids—it doesn't look like a recycled scenario,

but it's also possible that the alchemist reconstructed the room, or this is a new, unused room.

There are too many possibilities."

Li Ang scratched his head, the leather gloves rubbing against the metal helmet, making a creaking sound.

"The handwriting in this letter is messy and blurry, slanted to the right,

and it's all in English.

I don't know if the system's translation function secretly went online, changing the foreign tadpole script into English,

or if the world uses English, and that travel diary was specially encrypted."

Li Ang pondered for a moment, took the envelope to the sink, dipped his leather gloves in water, and carefully smeared it on the envelope and letter, trying to find hidden content.

The result of the attempt was naturally a failure.

Li Ang then took the letter to the door, aligned the words on the letter with the keyhole, and moved it back and forth,

to test whether the keyhole was fake, and its actual function was to be activated by the letter.

The result of the attempt was, of course, another failure.

"Okay, I knew these two unrelated things couldn't work."

Li Ang put away the letter, turned and walked towards the metal cabinet, fiddled with it for a while, but still to no avail.

"I can't find it... the key to open the door or unlock this suit..."

Li Ang sat on the edge of the bed, staring blankly at the faucet in the sink.

"Wait..."

His wandering gaze focused on the wall above the sink, where there should have been a mirror,

but after the mirror was removed, only a broken screw, used to fix the mirror, was left sticking out halfway.

Li Ang got up and walked forward, pulling, twisting, turning, and prying at the screw,

but still couldn't remove it.

Fortunately, the leather gloves were strong enough, otherwise his hands would have been scratched by the sharp tip of the screw.

"If this is a carefully designed escape room, everything in the room should be useful..."

Li Ang pondered for a moment, turned and walked towards the bed, picked up the bed sheet,

pierced it with the screw, and tore the bed sheet into strips.

"No interlayer, what about the mattress?"

Li Ang took the mattress off the spring bed, placed it on the sink, and pressed it against the screw, piercing the surface of the mattress.

The gloves were too clumsy and thick to perform fine work, and he couldn't tear the mattress apart,

but with the help of the screw, Li Ang put in some effort,

tore the mattress apart, revealing a pile of white foam and a painting.

"As expected!"

Li Ang perked up and picked up the painting to examine it carefully.

It was a crayon drawing, with a naive style and bright colors, probably by a child.

It depicted a glass window,

and a little girl lying on the floor, looking at the glass window with big, longing eyes.

"What does this mean?"

Li Ang flipped the drawing over. "Why would the person setting up the dungeon put the painting in the mattress? Are they implying that I stole his precious treasure, so I have to be punished?

Could this be a trap set by Officer Wang?"
