The surging water was hitting his body, and Li Weiyin curled up and shrank in the corner, and could feel the temperature of his body dropping rapidly in this cold winter night.

He could not breathe or move. The water splashed onto the wall, accompanied by Liang Xuewen's crazy laughter.

Too cold.

Li Weiyin tried to move and avoid the spray of the high-pressure water gun. He was shot in the head by the water column, choking a big mouthful of water, lying on the ground and coughing constantly, his face gradually turned pale.

"Enough... Lao Liang, if this continues, it will really kill people."

Wang Dafu pressed Liang Xuewen worriedly and turned off the water valve. Liang Xuewen threw down the water gun, sat by the bed, raised his legs and lit a cigarette.

"This thing is so fucking useful. You should have thought of this method long ago."

Since the incident of Lan Silin attacking the instructor, the academy has specially installed a high-pressure water gun in the innermost boring room, intending to use it to spray the students detained from time to time to avoid students pretending to be dead and to avoid the need to open the cage.

The coarse-grained cement floor was full of potholes and water stains. There were no drainage holes in this place, and water flowed out of the fence gate and was everywhere. Li Weiyin lay on the ground, looking silent.

Seeing that he was not moving, Liang Xuewen kicked the prison door irritably again:

"Lee Weiyin, don't pretend to be dead, move!"

Li Weiyin gasped and turned over with difficulty, lying in the water.

He was in a daze and seemed to be about to fall asleep at any time, but he kept forcing himself to refuse to close his eyes.

The small window on the wall casts the moonlight, and as time goes by, the bright moonlight cut by the fence gradually swims from the ground to the wall. Li Weiyin's gaze unconsciously stares at the moonlight on the wall until at some point, his pupils shrink slightly.

He tried hard to sit up and turned to look outside the prison. Instructor Wang, who was in charge of the guard, was already lying on the bed and snoring. There was silence around him.

He dragged his tired body and leaned against the wall bit by bit, stroked the potholes on the wall with his fingers, his lips trembling, his eyes closed, and silently chanting in his heart.

Horizontal dots, dots, dots, horizontal...

...

...

A few weeks ago.

"As the speed of a naked man running wildly, the time should be almost the same, right?"

Mr. Demon took a sip of coffee and walked slowly into the dull room. He walked into the corner, dragged Liang Xuewen out, closed the door of the dull room, found out the keys, sat on the clean floor, roughly measured the location of the light outside, and drilled a shallow hole in the wall with the key.

Then another shallow hole was punched to the right of the hole.

Another one was hit on the right.

Then, twist the direction of the key and draw a horizontal line.

Mr. Demon did it very seriously, as if he was painting. He was still humming:

“

The End of Heaven

The Horn of the Sea

Knowledge and friendship are falling

A pot of turbid wine is over and over again

Don't dream of the cold tonight

...

A pot of turbid wine is over and over again

Don't dream of the cold tonight

…”

After carving a long piece of characters, Mr. Demon sat on the ground, crossed his legs, pinched his chin, and looked at his work with interesting interest, muttering:

"And...what would you do? Lee Weiyin."

He suddenly stretched and took out two lenses from his pocket - which were taken from Liang Xuewen's broken glasses. He walked to the window, overlapped the two lenses, and slowly separated them, watching the gradually flipped images in the lenses, slowly narrowed his eyes, and looked up at the window.

...

...

...

It's the Morse code.

Li Weiyin easily confirmed this point. The drilling holes on the wall are very shallow and new, and should have been left within two months. From the time point of view, it is likely that it was Lan Silin's work.

After reaching this conclusion, Li Weiyin's heart sank slightly.

This is too abnormal.

If this is really left by Lan Silin, who did he leave it to?

If this is really left to me, it means that Lan Silin had already started to plot against herself before entering Kanglong Academy.

I found the first letter and the second letter, and even expected that I would not play according to common sense, and used this to force myself to the army. Finally, I predicted the existence of the "betrayer" and sent me to jail...

If all this is really in Lan Silin's plan... Can such a layout and such wisdom really be possessed by humans?

An extremely depressing feeling burned in Li Weiyin's chest.

But he closed his eyes and instinctively began to think about the meaning of the two lines of Morse code.

Each set of dots and horizontal arrangement corresponds to an English letter. The message left by Lan Silin is very simple:

deathbed struggle.

"sucker Punch".

Judging from the literal meaning of this sentence, it seems that Lan Silin had long expected that she would be locked in a boring room, so she left a sentence in advance to ridicule herself. With his personality, such things may not be impossible.

But what if not?

What if this is actually a riddle?

...

...

...

The day after being locked in the boring room, Li Weiyin's actions began to become weird.

He did many useless things: he tried to shake the indestructible iron fence desperately, trying to remove it, and then searched in the boring room less than ten square meters, as if looking for some tools that could help him escape. He even reached into the mouse hole in the corner, but still found nothing.

These abnormal actions made Instructor Wang, who was guarding the bored room, feel uneasy. He threatened him more than once to use a high-pressure water gun. Whenever he threatened like this, Li Weiyin would restrain himself a little.

Instructor Wang always felt uncomfortable. All this was not the taciturn "dumb" style in his impression. He had been hiding under the nose of the academy for so many days, and the impression he left was cunning, capable and courageous. Thinking of this child under fifteen who once blinded Liang Xuewen's eyes by himself, Wang Dafu unconsciously felt creepy from the bottom of his heart.

In the afternoon, Wang Dafu felt a spasm in his stomach and wanted to go to the lounge to relieve his skills. He walked closer to the fence door carefully, and after confirming that there was no problem with the door lock, he left the bunch of keys at his waist.

Li Weiyin, who was sitting in the corner, immediately rushed as soon as he left. He hurriedly walked towards the foul-smelling tub by the wall, moved it to the window at the corner, carefully stepped on the edge of the wooden barrel, used it as a step, and barely reached the small window half a meter square.

As Lancilin Moss's code shows, he tried every possible way to escape like a normal, dying man, and although he believed from the bottom of his heart that these practices were futile, he could only take a gamble like this.

He bet that there was a mystery in Lan Silin's words, and this small window was the only place he had not checked.

He reached out his hand and grabbed the railing of the window and shook it hard for a few times. There was no sign of loosening. Li Weiyin's heart was slightly dark, and he felt a sense of loss of hope.

Just as he was about to jump out of the feces bucket, his aftermath swept to the corner of the window and was suddenly stunned.

On the outside of the window, there are two old glasses.

Li Weiyin picked up the two glasses and placed them in the sun to examine them carefully.

It was just a very ordinary farsighted glasses, commonly known as reading glasses, with a lot of dust on them. Thinking of the fact that Lan Silin attacked the instructor and Liang Xuewen changed into a new pair of glasses afterwards, it is not difficult to guess that this is the glasses left by Lan Silin, which originally belonged to Liang Xuewen.

But there is nothing strange about the glasses themselves, they are just two ordinary convex lenses.

When the concept of convex lenses was formed in Li Weiyin's mind, his heart was like a thunder blew up. He pursed his lips tightly and said to himself in his heart: It's not wrong.

He carefully pinched up the two lenses, overlapped them together, and slowly opened the distance, one in front and the other in back, lowered his head and looked over the convex lens in front.

When the distance between the two lenses reaches a certain level, the refracted imaging gradually distorts and the mirror image is reversed.

At the same time, it has also become bigger.

This is similar to the principle of a telescope.

He took the two crude lenses as telescopes and looked carefully at the view outside the window without leaving any clues. He kept muttering:

“Spraying…spraying…”

When Lan Silin talked to the so-called "sister" on her parents' visit day, she once told her to bring a few cans of spray paint next time she came.

At first, Li Weiyin didn't understand Lan Silin's intentions. Until now, after connecting these seemingly unrelated clues, a vague idea gradually took shape in my mind.

He struggled to death like an ordinary person—so he climbed up the windowsill.

Then there is the "teleoscope", then "spraying".

Outside the window is a hill. Further away is the farmland. A large truck was parked on the dirt road. The driver got out of the car and was in the ridge of the field. The view here is very wide, but nothing related to "painting" can be seen.

After watching for a while, Li Weiyin's heart became more and more anxious. It would not take long before Wang Dafu would come back. It was already afternoon and it would soon become dark. Once it was dark, it would be even less likely that he would find useful clues in the darkness. He racked his brains and carefully observed every place within his reach, but could not find what Lan Silin left behind.
