A window soon appeared on the screen, containing all the contents of the video files, and the file names were all dates.

The videos were copied by him from the surveillance room. Because doctors in psychiatric hospitals have the need to understand the daily behavior of patients, it is common to copy surveillance video.

Dr. Zhang clicked on a video, the date below......

It was yesterday.

Video playback starts......

The screen shows the image of a ward, because it is night vision mode, the picture is black and white, the camera angle is tilted from top to bottom, and in the middle, there is a bed, and a person is lying on the bed. The time in the video is 4 a.m. At this time, the patient is sleeping, so the picture seems to be still.

Dr. Cheung glanced at the date and time to make sure he hadn't mistaken the video, and pressed the fast-forward button.

Afterwards...... Nothing has changed.

If it weren't for the number of seconds, it would have given the illusion of looking at a still life photograph again.

……

……

This stillness lasted until seven o'clock in the morning, when the person in bed woke up violently and sat upright.

Immediately afterward, he began to brush his teeth and wash at a "fast-forward" pace, and then went in and out of the room. The movement becomes like a twitch due to the increase in speed.

The ward in this shot is in the "mild ward", so the people in the lens are not like those in the intensive ward who want to cut people at any time or those exhibitionists who don't want to wear clothes and like to show their reproductive organs.

…… He's just a patient with few mental symptoms...... These behaviors seem to be extremely normal.

And this is also the reason why Dr. Zhang has accelerated the playback rate, because he knows that there is nothing to watch during this time, and another reason is that he has watched this video three times today......

Ten minutes later, the time on the screen came to three o'clock in the afternoon. The patient was sitting idly on the bed when his head was inexplicably lifted upward.

Although the surveillance footage is a little blurry, you can vaguely see that he is looking in the direction of the ward door......

Dr. Zhang frowned again and slowed down the playback......

He ...... What exactly do you see? ”

This was the third time he had asked himself this question today. But he still didn't have an answer

Immediately after, the patient in the picture stood up. He poked his head forward and swayed out of the camera's range. It looks like he's out the door...... But less than a minute later, he walked into the picture again.

Dr. Zhang rubbed his dry eyes and stared at the screen.

I saw the man come to the bed and sit down, his head slightly bowed...... Motionless.

Suddenly, without warning, his head rose at an unbelievable angle, and he frantically waved his arms and mouthed wildly, and screamed.

This change can be described as sudden, so when he saw this paragraph for the first time, Dr. Zhang was also taken aback...... But now he has long been mentally prepared, and at this moment, he is staring intently at the screen

The video in the ward can only record the picture, not the sound, so Dr. Zhang can only see the patient's frantic appearance, but he doesn't know what he is shouting......

After a while, a group of staff members in medical uniforms rushed into the scene and tied up the patient with restraint straps...... A few minutes later, he was lifted onto a flat car.

During this time, he constantly twisted his body wildly, howled hard, and spat was thrown everywhere, like an enraged beast, and just judged two people.

……

Dr. Zhang has been in a psychiatric hospital for some years, and it can be seen from this series of behaviors alone that this person is already in a very severe manic episode.

Although the patient had a history of mania, it was a very slight tendency, and even a great stimulus could not necessarily induce it, and the person's recent examinations indicated that he should have been completely out of the condition.

"Is there anything outside the door?" Dr. Zhang muttered to himself

And at this moment, this video also came to an abrupt end.

He let go of the mouse and leaned back into his chair to reorganize the context of the video.

"Until three o'clock in the afternoon, the patient was all right, and he seemed to have noticed something suddenly, and then walked out of the room, and after just a minute, he was back in his seat.

And then...... Just suddenly crazy?

That is, in 1 minute outside of that shot

…… Something must have happened.

What is it?

Although he didn't know the answer to the question, he instinctively thought of the disgusting face...... For some reason, from the first time I saw him, I knew that it must all have something to do with him.

Dr. Zhang glanced at the time, the time shown on it was 8 p.m., it was already pitch black outside the window, and he looked at his reflection in the dark glass background, his eyes were full of exhaustion and doubt......

"No! I've got to figure it out! ”

He let out that vicious expression again, grabbed the key on the table, and walked out of the office.

Of course, he wouldn't go directly to the ward to find the new patient with the scar on the corner of his mouth and question him, that would be no different from a fool's behavior.

What he wanted to go to was the room in the surveillance footage

A few minutes later, he was in the room...... Opened the door and reached out to scratch the wall.

With a "pop", the lights in the ward were turned on.

In front of the light was a neatly laid bed, on the other side was a loose-leaf window, as required, wrapped in an iron guardrail, and on the left side of the room against the wall was a table and a row of wardrobes, and on the other side, a decent set of washstands. The floor is white tile, with some cracks, but it's clean.

Obviously, after the patient who had suddenly gone crazy was carried out, there was a cleaning of the place, and at this moment, there were only these things in the entire ward, which could be seen almost at a glance.

But Dr. Zhang still looked around very seriously, touched the door frame twice, and then walked to the hospital bed......

Actually, he wanted to do this during the day, but at that time, there was a constant flow of people around, and there were too many messy things, so this plan was never implemented, and now, the whole hospital is just one doctor on duty, so this is almost the best opportunity.

I saw him sit on the edge of the hospital bed, recall the location of the patient in the video, and move his butt to the left.

Then, mimicking the memory of the patient in his mind, he lowered his head, and then jerked himself up.

In my memory, that man's head should be from this angle.

At this moment, Dr. Zhang was surprised to find that the place he was staring at was actually a long distance away from the door

……

And what he's looking at at the moment ...... It's the wall of the ward.
