"Walls?" Dr. Zhang put on a bewildered expression......

He recalled the scene in the surveillance video of the patient suddenly raising his head, and felt inexplicable......

"What is he staring at the wall for?"

The wall was bare, unscribbled, white-painted, and empty. For a moment, Dr. Chang seemed to feel that there was something indescribably strange about the wall.

Immediately after, he looked at the camera on the door frame......

Standing up, he reoriented himself towards the camera and walked to the wall along the route of the patient in the video......

Since the camera is directly above the door frame, his current position is already out of the range of the surveillance frame.

The man just looked up at the wall for some reason, and then walked to where he was standing...... A minute later...... Just crazy?

"What's going on?" He muttered to himself aloud, thinking about the scene of the patient sleepwalking against the wall in the empty room at that time, and a trace of panic in his heart for no reason......

"Did he see something? That's why you came here? Is there anything in this room that I can't see......? ”

Dr. Zhang shook his head to stop his bizarre thoughts.

Followed by...... He began to bang on the wall,

"Bang...... Bang"

The sound of the wall was dull, there was not a single sound of air, and the wall was undoubtedly solid......

Of course he knows that.

Because there are many patients with neurasthetic breakdowns in the psychiatric hospital, all the wards here are made of solid materials with strong sound insulation. In other words, there is nothing to hide in this wall, and it is impossible for the patient to lie on the wall and hear the sound outside.

He scratched his head in confusion...... After that, I came to the door of the ward.

When I opened the door, I was greeted by the horizontal corridor where I came, opposite the wall, and on the side where I was, there was a whole row of single rooms far apart, and there were no patients on either side of this room these days......

The corridors extend to the corners of the building, with overhead lights shining on the tiles on the floor, reflecting the outline of the tubes, ending on the left with a staircase leading up and down, and a window on the right.

Because there is a strict schedule in the hospital, the patients have already returned to the wards at night, and the corridor must be empty, Dr. Zhang has been working in this psychiatric hospital for a long time and knows the structure of this building well, so he just casually glanced at both ends of the corridor and withdrew his gaze.

He came to the opposite side of the wall where he had just stood in the room, knocked on it, and then looked carefully at the tiles under his feet, then the ceiling above his head, and the wall opposite

Immediately afterward, he discovered...... There is nothing suspicious on this side of the corridor either.

Don't...... Did the patient really just have a sudden relapse of mania and get worse without any triggers?

He couldn't help but think about it, but as soon as the idea came to him, Dr. Zhang laughed self-deprecatingly, he knew that it was impossible, because it was not in line with the development of the disease at all.

"I'm sure there's something I haven't found......" he muttered incredulously, and a voice inside him kept reminding him that it was all the work of the new patient......

So, Dr. Zhang went back to the ward....... Standing by the wall, lying on the wall with open hands, groping as if to sweep the wall with dust.

The wall is not big, so it's easy to touch it.

Suddenly, his hand stopped, and he felt a strange touch between his fingertips and the wall

…… He looked intently, and there was a small strange spot on the white wall paint, like a scratch made with a fingernail, but the marks on the wall paint were not very sharp, but sunken inward, and could not be seen without looking closely.

Dr. Zhang stared at it with a frown, and he was surprised to find that there were several similar scratches not far from each other near the scratch

Could it be that the patient scratched it?

But why did he scratch?

Dr. Zhang thought about it,

Suddenly, his eyes dilated, as if he had thought of something.

Yes, he finally remembered what the vague weirdness he had when he saw this wall just now.

......

......

People have a problem, that is, they often see a picture, but the brain selectively does not remember it...... It's like a pair of shoes that have been worn for many years, but surely few people know about how many holes in them are used to wear laces......

It's like this wall, and Dr. Zhang visits these wards almost every day, and on the wall of each room is a timetable — a form that reminds patients what time to get up, what time to take their medications, and so on.

But until now...... He realized that in this room, the watch was gone!

And almost in the next second, Dr. Zhang concluded that this watch was definitely torn off by the patient who suddenly went crazy.

And he is also a doctor after all, his brain is not too stupid, he knows, this must be a message left by that patient to himself!

Dr. Zhang's eyes flashed with inspiration, and he rushed out of the ward quickly, and at the same time took out the key in his pocket.

The doctor on duty in a psychiatric hospital will have a key that will open all the wards in the current ward, which is also designed to prevent some patients from locking themselves in the ward. So, he went to another ward next to him and opened it directly with the "master key".

Then he didn't even press the light, and with the light in the corridor, he removed the "schedule of work and rest" on the wall! Then he ran back to the ward he had just had, and hurriedly pressed his hand to the wall again, groping for the scratches that were on the top of the side.

Finally, he touched a strange place, which was very special to the touch, sticky, and only after the tape was torn off, this feeling could be left. And using this place as a starting point, I found three other sticky "duct marks" around it, which happened to be the four corners of an A4 piece of paper.

Dr. Zhang knew that he had guessed correctly, so he couldn't wait to pick up the "schedule of work and rest" in his hand and aim at the four corners, and pasted the paper again.

...... In this way, the wall was restored to its "original state".

He looked at the much more pleasing wall and took a deep breath.

"Let me see what you want to tell me......" he said affectionately and solemnly, slowly stroking the "timetable", feeling the scratches under the page......

"Get up...... Wash...... Radio gymnastics....." Dr. Zhang muttered to himself.

"8 a.m.!"

Suddenly, he stopped, and the first scratch appeared on the 8 o'clock table.

He thought about it for a few seconds and found that he still couldn't understand what the patient meant, so he didn't dwell on it and continued to explore.

The next few scratches appeared again in the time period of "13 o'clock", "16 o'clock" and "20 o'clock".

At this time, as long as you think about it a little, you will know that what the patient wants to tell the doctor should be these sets of numbers!

Dr. Zhang took out a pen from his jacket pocket and wrote directly in the space next to the "schedule of work and rest"-

“8、13、16、20。”

He frowned, looking at the numbers in front of him, feeling clueless...... According to his understanding, the patient should have left scratches on the top of a few words, and then pieced together a complete sentence or a name, location and other information, what is it like to leave four numbers, is it a neurotic foresight of the next two-color ball number? Or is there a safe that requires a code to open and hasn't been found on its own?

Well, compared with these nonsense conjectures, it seems that the most reliable possibility is that these are just a few pointless "buttons" on the wall by a neuropathy!

"Alas...... Isn't it always me who is figuring out to myself? ”

Dr. Zhang sighed, and for a moment felt as if he had been tricked. The original enthusiasm for "chasing the truth" is gone.

......

......

In the dead of night, it's always a time when people are inspired~

At the moment when he was about to scold himself and let himself quickly give up this unrealistic delusion......

He paused for a moment

"Phone Number !!"

Dr. Zhang didn't say it silently in his heart, but shouted it out!

In this era of mobile phone popularization, he can't remember the last time he called the "landline number", but at this moment, he is extremely sure that this is the meaning of this set of numbers.

So he quickly pulled out his mobile phone and entered the phone number directly

“8131620”

A mentally ill person who suddenly went crazy left a phone before going crazy, and the other end ...... What could it be?

He thought as his fingers began to tremble over the "dial" button......

After a few seconds, he seemed to have finally made up his mind, "Fight!" "All the same, press it!

"Toot ———— Toot ————"

There was a busy sound

Dr. Zhang felt a little flustered.

Suddenly, the phone was connected, and immediately after, a shrill voice rang

"Hey—hey—hey"

......

At this moment, Dr. Zhang's heart jumped to his throat, he was very scared, but he didn't know why, as if this laughter evoked some kind of fear in his heart.

In the next moment, Dr. Zhang's eyes opened suddenly.

......

......

......

In front of me, there is a somewhat moldy wall, which looks like it was built with large bricks in the last century, and after nearly a hundred years of erosion, it has become bald. From the left and right sides of the line of sight, you can see the edge of this wall, which connects the other two walls at right angles.

As you can tell from this scene, it's a very small room, and it's definitely not been visited for decades.

But Dr. Zhang, as a person who had just opened his eyes, found himself in an unfamiliar environment, and he didn't have the heart to care about it.

"!"

He reflexively cursed like anyone who wakes up from a nightmare, and then quickly looked down at himself, and then he realized that he was sitting in a wooden chair.

Immediately, his first thought was to sit up quickly, but the moment he stood up, a huge force violently pulled him back to his seat.

Only then did he realize that he had a belt around his waist, which was tied to him like a seat belt in a passenger car.

"What the is this!!" He cried out in horror, and realized that his hands were not tied, so he panicked and tried to untie his belt......

Suddenly!

"You're awake......"

A male voice suddenly came from his left side.

"!"

Dr. Zhang was startled again, and reflexively scolded, and at the same time, he also turned to look in the direction where the voice came from.

In the open space next to him, there was a man, less than 30 years old, with eyes, wearing a hospital gown, and it could be seen that he was not tall, nor very strong, and his hair was a little long, and at this moment, this person was staring at him intently.

At this time, Dr. Zhang had already untied the belt around his waist and quickly stood up, he tried his best to recover from the "serial shock" just now, and cautiously distanced himself from the other party.

"Who are you?"

He asked a question that he would ask when he met a stranger.

And the other party obviously knew that the other party had just woken up and would be in such a panic, so the man tentatively raised his hands, pressed them down, and responded

"Calm down, I only woke up a few minutes before you...... My name is Liu Yi! ”

Dr. Zhang is also relieved now, he looked the stranger on the other side up and down, and found that the other party's body was thin and weak, and at first glance he was a standard otaku, even if the other party was hostile, he might not be able to beat himself, so he also relaxed a little and began to observe the surrounding environment.

This is a small space full of musty smell, about less than 20 square meters, surrounded by bald walls, hugging black and red bricks, on a wall behind him, there is a half-open waste wooden door, due to the angle, I can't see what is outside, but there is some faint light shining in, otherwise I may not be able to reach out here.

The floor was cracked and somewhat rotten, and it was hard to step on. The ceiling is low enough to be touched when you jump up, and there is a small round hole in the middle that looks like it was used to connect the wires to the lights, which of course have long since rotted......

It looks like a building from decades, even a hundred years ago, with no decoration or furniture on all sides, just bare walls, and in the middle of the room, there are two chairs.

And these two chairs will certainly not be included in the ranks of furniture, because they look like they have been modified from one kind of "execution chair", with a restraint belt at the waist and abdomen...... At the top of the back of the chair, that is, the position of the "head", five thick wires stretch out, one on the top of the head, two on each side, which sketches the shape of a head, but it is obviously several circles larger than the head, and cannot touch the head.

Dr. Zhang frowned and couldn't help asking

"What the hell is this?"
