"Wall?" Dr. Zhang put on a confused expression...

He recalled the situation where the patient suddenly raised his head in the surveillance video, and felt inexplicably...

"What did he do when he stared at the wall?"

The wall was bare, without any scribble, painted with white paint, and was empty. For a moment, Dr. Zhang seemed to think that the wall was indescribable.

Immediately afterwards, he looked at the camera on the door frame again...

Stand up, adjust the direction of himself facing the camera, and follow the patient's route in the video to the wall...

Since the camera is directly above the door frame, it has left the scope of the surveillance screen at this position now.

Speaking of which, the man just raised his head for no reason, looked at the wall, and then walked to where he was now standing... a minute later... went crazy?

"What are you doing?" He said to himself, thinking about the scene of the patient sleepwalking against the wall in the empty room at that time, and a hint of panic appeared in his heart for no reason...

"What did he see? That's why he came over? Could it be that there is something in this room that I can't see..."

Dr. Zhang shook his head and asked himself to stop those strange ideas.

Then...he began to hit the wall,

"Bang...bang"

The wall made a dull sound, without any empty sound, the wall was undoubtedly solid...

Of course he knew this.

Because there are many neurasthenia patients in mental hospitals, 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 patients to lie on the wall and hear the sounds outside.

He scratched his head in confusion... and then came to the door of the ward again.

After pulling the door open, there is the horizontal corridor when I came, opposite the wall, and on the side where I am, a row of single wards are very far apart. Moreover, in the past few days, there have been no patients on both sides of this ward...

Both ends of the corridor extend to the corner of the building. The light above the head shines on the tiles on the ground, reflecting the outline of the light tube. At the end of the left is a walking ladder connecting up and down, and to the right is a window.

Because the hospital has strict schedules, the patients have returned to the ward at night, and the corridor must be empty. Dr. Zhang has worked in this mental hospital for a long time and knows the structure of the building well, so he just casually glanced at both ends of the corridor and then withdrew his gaze.

He came to the opposite side of the wall where he was standing in the ward. He first knocked, then looked at the tiles under his feet, then the ceiling above his head, and the wall opposite.

Immediately afterwards, he discovered... there was no suspicious place on this side of the corridor.

Could it be...that patient really had a sudden recurrence of mania and worsened without any cause?

He couldn't help but think, but as soon as this idea came to light, Dr. Zhang smiled at himself, knowing that this was impossible because it was not in line with the development of the disease.

"I must have something I haven't found..." He muttered without believing in evil. In his heart, a voice kept reminding him that all this was done by the new patient...

So, Dr. Zhang returned to the ward... standing by the wall, spread his hands and lay on the wall, fumbled as if he wanted to wipe the wall ashes.

This wall is not big, so it is easy to touch it all.

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

...He looked over and saw a small strange piece of space on the white wall paint, like a scratch made with his fingernails, but the marks on the wall paint were not very sharp, but were sunken inwards, and they could not be seen without looking carefully.

Dr. Zhang frowned and stared at it, and he was surprised to find that there were several similar scratches nearby that were not far away.

Could it be that patient who scratched?

But why did he scratch?

Dr. Zhang thought about it,

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

Yes, he finally thought of the faint weirdness when he saw this wall just now.

......

......

There is a problem with people, that is, they often see a picture, but their brain selectively does not remember it... It's like a pair of shoes that have been worn for many years, but few people know that there are several holes in the shoes that wear laces...

Just like this wall, Dr. Zhang goes to these wards to check patients almost every day, and there is a timetable on the wall of each ward - a form used to remind patients to get up at what time and take medicine, etc.

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

Almost the next second, Dr. Zhang concluded that this table was definitely torn off by the patient who suddenly went crazy.

He is also a doctor after all, and his mind is not too stupid. He knows that this must be a message left to him by the patient!

A flash of inspiration in Dr. Zhang's eyes, he rushed out of the ward quickly and took out the key in his pocket.

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

Then he didn't even press the light, and took advantage of the light in the corridor to remove the "working schedule" on the wall! Then he ran back to the ward just now, pressed his hand to the wall again, and began to explore the scratches.

Finally, he touched a strange place again. The touch was very special and sticky. This feeling could only be left after the tape was torn off. Moreover, with this place as the starting point, three other sticky "tape marks" were found around, which happened to be the four corners of an A4 paper.

Dr. Zhang knew that he had guessed correctly, so he couldn't wait to pick up the "working schedule" in his hand and point it at the four corners, and paste the paper again.

......In this way, the wall returned to the "original state".

He looked at the wall that he had liked a lot and took a deep breath.

"Let me see what you want to tell me..." He said affectionately and seriously, and slowly stroked the "timeline" and felt the scratches under the page...

"Get up...wash...broadcast gymnastics..." Dr. Zhang muttered to himself.

“8 am!”

Suddenly, he stopped, and the first scratch appeared in the 8 o'clock form.

He thought for a few seconds and found that he couldn't understand the patient's meaning, so he didn't struggle and continued to explore.

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

At this time, just think about it for a moment and 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 shirt pocket and wrote it directly in the gap next to the "work and rest schedule"-

“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 words, and then pieced together a complete sentence or a name, place and other information. What is the matter of leaving four numbers? Could it be that the psychopath foresaw the next Double Color Ball number? Or is there a safe that requires a password to open yet?

Well, compared with these nonsense guesses, the most reliable possibility is that these are just a psychopath who makes no sense to "buckle" on the wall!

"Oh...hat I've always been thinking about it myself!"

Dr. Zhang sighed and felt for a moment that he seemed to be being played with. His original enthusiasm for "chasing the truth" was gone.

......

......

When it's late at night, people are always inspiring.

Just when he was about to scold himself and ask himself to give up this unrealistic delusion...

He was stunned for a moment

"telephone number!!!"

Dr. Zhang did not recite silently in his heart, but shouted out directly!

In this era of popular mobile phones, he can no longer remember when the last time he called the "landline number", but at this moment, he was extremely sure that this is the meaning of this set of numbers.

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

“8131620”

What will be the phone number left by a mentally ill person who suddenly went crazy before going crazy?

He thought, his fingers began to hang tremblingly above the "Dial" button...

A few seconds later, he seemed to have finally made up his mind and pressed down like "Try it!"!

“Dou————————————”

A busy sound

Dr. Zhang felt a little panicked.

Suddenly, the phone was connected, and then a sharp voice rang out

“Hey—hey—hey”

......

At this moment, Dr. Zhang's heart suddenly jumped into his throat. He was very scared, but for some reason, it seemed that this laughter aroused a certain fear deep in his heart.

Just the next moment, Dr. Zhang suddenly opened his eyes.

......

......

......

In front of me is a slightly moldy wall, which looks like it was made of large bricks in the last century. After nearly a hundred years of erosion, it has become alopecia areata. The edge of the wall can be seen at the right and right sides of the line of sight, connecting the other two walls at right angles.

From this scene, we can see that this is a very small room and it has definitely been for decades.
