The voice appeared behind him, and in the dark, Sun An couldn't hear the commotion downstairs, so the footsteps were very clear, as if someone had come out of the stairwell and walked towards him step by step.

He couldn't tell what kind of shoes the other person was wearing by the sound of footsteps, let alone the height and weight of the person, and he didn't even know if the footsteps were real.

It is impossible for Bai Yue to step on such footsteps to approach him, and they have already said that Bai Yue will not come here anyway, she should have sealed the door of the stairwell by now, hiding and waiting for the matter to be over, if the footsteps are true, it means that Bai Yue has had an accident, was killed or kidnapped, and it was the enemy who came.

Auditory hallucinations are more likely, like the footsteps on the stairs before, which is to increase Sun An's psychological fear, and if he is in such an environment for a long time, he will be driven crazy, and the "King of Fear" has the ability to cause substantial damage, but no one can defend and resist.

But even if he knew that it was an auditory hallucination, Sun An had to care, because the footsteps were getting closer and louder, and finally stopped behind him.

He sat on the roof of the building, nearly 20 meters high from the ground, and could not see, and there were still very serious injuries on his body, and if he fell, he would have to fall to his death, and the possibility of falling and disabled was much smaller, and the other party had already come behind him, should he push his back, strangle his neck, or give him a shot of anesthetic, so that he could not move?

Sun An waited silently, every second that passed, the tension in his heart would increase by a point, if he kept holding the idea that he would not be harmed by the illusion, it would really be over, the illusion really could not cause harm, but he himself would cause harm to himself.

Hallucinations affect the brain, the brain controls the body, when the brain thinks that it is touched, it may affect the muscles through the nerves, so that he can feel the touch physiologically, the pathogenesis of hysteria has not yet been fully understood, but this is indeed a mental illness that exists, and the inhibitory hysteria reaction can make people blind, deaf, voiceless, and even paralyzed, and the patient's body is completely unhindered, and nothing can be detected.

In other words, the brain thinks you're really paralyzed and you can't move, the brain thinks you're blind, you can't see, and the brain thinks you're dead, and you lose your vital signs, eventually leading to brain death.

Hypnosis is not something that only exists in film and television, but it is real, everyone has the possibility of being hypnotized, but the state is different, the depth is different, and the ancient Chinese "Zhu Youshu" is a higher and deeper thing than modern hypnosis.

To put it bluntly, hypnosis is to deceive the brain, and the placebo effect is the most common brain deception.

Sun An knows how to use suggestion, knows that illusions cause hypnosis, and if he really "feels" that someone pushes him, he will fall off the roof.

The sense of touch has not been affected by the illusion, but that does not mean that the illusion will not affect the sense of touch, the other party hides this big move very well, and he can't bear it at all when he suddenly uses it.

That's why he was so frightened when he went up the stairs just now - what if the hand he was holding had been fake? If it was an illusion from the beginning, then he should still be sitting in the classroom, never going downstairs, avoiding the bathroom, maybe even lying in bed - or on the roof of an apartment building - the so-called reality is only a part of the illusion, since the passage of time in the illusion will be different from reality, then it is likely that he has just gone to the top of the building, holding up his night vision goggles and looking around.

Everything can be an illusion, including your own appearance, growth, this world may just be a game, after the character is established, you will automatically get a memory, part of which is the common memory with other characters.

It is not known whether this world is a game or not, but about the illusion, Sun An thinks too much, he sits on the edge of the roof and is nervous on his own, tormented by his own brain, his body is shaking, and the people below are thrilled to watch.

............

In the office building, Liu Qingmei, Qu Wei, Wang Shenghong and Ma Jingsong were not as nervous as before, they successfully subdued a person and captured a gun, and the enemy's strength did not seem to be as terrible as they imagined.

Ma Jingsong still didn't know why they came, at first, he thought that the three of them were just idle, looking for nothing to do, so he ran in to see, since Liu Qingmei shot a person, he realized that things were more complicated than he thought, but he still didn't know why they wanted to explore here.

Liu Qingmei is indeed the goal, that is, to find the person Sun An is looking for, although I don't know who it is, but I always feel that what Sun An is looking for is definitely not an ordinary person, and it should be recognized at a glance, it is inconvenient to talk here, and Bai Yue does not reply to text messages, so she has to look for it by herself with her head bored.

Out of the office door, they continued to search forward, and came to the next office, which was an archive room, and the door was not locked, and it could be pushed open, and there was a man sitting in the office, a man in his thirties, who was sleeping on a desk.

There are only two desks in the archive room, in the innermost part of the room, against the window, and the other three walls are iron cabinets, the space is very small, the curtains are closed, and the person lying on the desk sleeps very deeply, even the door is open, and the curtains are blown by the breeze and his body does not wake up.

The four of them couldn't be sure if the person was a school worker, squatted at the door and asked each other with their eyes, if it was a bad person, they would ignore it, and then they might be attacked, and if it was a teacher, they couldn't go up and give him a stick, so that he could continue to "have a good rest".

In the end, Qu Wei came up with a good idea: "I quietly knocked him out in the past, anyway, he fell asleep, and I don't know who beat him, and we don't say anything about it, so we can rely on those bad guys." ”

This is indeed a good idea for the situation in front of them, the four of them walked lightly into the cramped office, closed the door, and nervously walked towards the desk, the man was still asleep, his head was resting on his arm, and it was estimated that his arm would be numb for a long time after waking up.

Liu Qingmei was at the front, she stared at the man for a while, turned her head to look around, and couldn't find a suitable tool, so she reversed the gun in her hand, held it like a hammer, and raised her hand.

............

"Oh!"

The onlookers downstairs collectively let out an exclamation, and they saw Sun An's head turn back violently, using too much force, so that half of his butt was crooked off the edge of the roof, and if he hadn't lifted it in time to maintain his balance, he would have fallen off.

This thrilling scene made many girls cover their mouths in fright, and there were more and more onlookers, and even some students in class ran out to watch the excitement - there was such a noise outside, and the teacher couldn't give a lecture.

............

"Oh!"

The exclamation from the window also startled Liu Qingmei, her hand was already raised, ready to be knocked at any time, and this exclamation also made her realize one thing - such a loud voice could not wake the "archivist", and he was probably not in a good situation.

At the same time as this thought appeared, Liu Qingmei heard a "chirp", and the door of a filing cabinet suddenly opened.
