“…????”

A very simple sentence is not called, but there are no other sounds in this room, so I can hear it very clearly.

But listening clearly does not mean listening clearly.

Everyone around was stunned. They didn't understand what Zhou Yan was talking about.

The criminal was lying on the ground, but why did this guy Zhou Yan talk to Sister Masako and Li Lei?

It seems that they are the culprits.

And Sister Masako... She was confused and wondered why Zhou Yan wanted to say that she was the real murderer.

After about a second, she finally came to her senses.

Zhou Yan didn't say to him, but to Li Lei leaning against him.

She turned her head and looked at the thin child beside her who was eroded by the pain, sweaty.

At this moment, Sister Masako seemed to have some illusion. She found that there was more sweat on Li Lei's forehead than before.

Is it because your fingers hurt even more?

......

Li Lei did hurt even more. He gritted his teeth and tried hard to stop calling out.

At the same time, he was frowning and looking at Zhou Yan in front of him.

"Brother Zhou Yan, what are you talking about?" He was in pain, puzzled, and even a little scared. Zhou Yan's appearance was so scary that he started to tremble all over his body.

"Hey, what the hell are you going to do!" Zheng Gangtie came over and pushed Zhou Yan for a moment: "He is our savior, why are you talking nonsense?"

Xiaogang yelled, obviously very dissatisfied with Zhou Yan's behavior. Judging from the situation, if Zhou Yan doesn't apologize quickly, he will beat Zhou Yan directly.

But Zhou Yan ignored Zheng Gangtie. He still looked at Li Lei with his eyes open. At the same time, he pointed at the person lying on the ground: "This person is actually not a criminal at all. In fact, he has been lying here since the beginning, right?"

Li Lei looked confused: "Brother Zhou Yan, what's wrong with you? I don't understand what you are talking about at all?"

"Yes, Brother Yan, don't scare people there, okay?" Liu Zhiyuan also said anxiously.

Zhou Yan still stared at Li Lei, but after a while, "Ha~ Okay." Zhou Yan smiled, then looked at the others... "I don't know if there is such a knowledge point in everyone's mind...that is: people who have just experienced a concussion will have their heartbeat faster!"

He has no beginning and no end, so he said this.

"Ah?" The people around were stunned again, even Li Lei, a hint of surprise flashed in his eyes, but they were hidden in a flash.

"Haha, how about it, even you didn't expect that the human body would have such a strange phenomenon." Zhou Yan looked at Li Lei again and said, "It's no wonder, because this phenomenon will not have any impact on the diagnosis and treatment of concussions, so it is rarely mentioned in the book. Unless you are a medical staff who have been engaged in neuromedicine for a long time, few people will know this reaction."

Indeed, concussion... will make a person's heartbeat, which is a useless knowledge point.

Even in clinical treatment, it is basically useless and will not take the exam. Even the most tricky medical professor will not use this kind of problem to make students difficult.

But... Zhou Yan knew about this phenomenon.

As for how he knew about this phenomenon, Zhou Yan himself was full of questions. Logically speaking, he was an unemployed vagrant and was not a doctor, and he had never studied neurology books. It was absolutely impossible for him to know such unpopular knowledge.

But...this knowledge appeared in his mind, and Zhou Yan was very sure that this phenomenon was true and could even explain its principles.

Its principle involves the brain's "self-protection" reaction.

Concussions are extremely common in daily life, such as being hit by bowling balls falling from the sky, children are playing with jokes, slapping each other's heads with bricks, and being hit on the back of the head by the buddy behind them with a wrench.

I believe everyone often encounters these phenomena.

After the head is hit hard, people will fall into a coma. Even if the brain is protected by the skull and does not suffer any great trauma, people will fall into a coma.

Don't ask why, because the human body has this protection mechanism.

This is commonly known as "smashed out".

After being knocked unconscious, the human heart will be beating rapidly to speed up the blood flow rate and transport blood and oxygen to the brain. This protective mechanism is spontaneous and starts to operate in a few seconds after the concussion.

Generally, within two hours, if the brain is not really damaged, or cerebral hernia, bleeding, etc., the heartbeat will gradually stabilize and the person will slowly wake up.

This...is why Zhou Yan finds it strange.

Because he had just touched the heartbeat of the "criminal" lying on the ground.

Not to mention speeding up, it is even slower than normal.

This is very unreasonable...

Unless... this person had no concussion at all, his coma had fainted due to medication and other reasons.

As soon as these words came out, the others present seemed to realize something.

The first thing I realized was Zheng Gangtie, who was closest to the "criminal" lying on the ground.

He frowned, half-kneeled, and touched the man's wrist.

Heartbeat is indeed very slow...

Liu Zhiyuan also leaned over and touched it, and then his face changed suddenly.

"What...what happened?" he wondered.

"Hey, are you making up here? Concussion will cause your heartbeat to accelerate? Really or false?" Zheng Gangtie shouted: "And, what does this have to do with the 'real murderer' of brother Li Lei?!"

Zheng Gangtie obviously does not have the relationship between Lu Qing.

"Haha~" Zhou Yan smiled: "Okay, then I'll tell you the truth about the whole thing again...

In this process, I hope everyone can understand one thing, that is... the 'criminal' lying on the ground is actually a victim, and all the culprits are actually always hiding among us... that is him!"

Zhou Yan pointed at Li Lei and said.

"At the beginning, we woke up and safely got out of the first room.

Then, everyone arrived at the factory hall.

Because of the countdown, we realized that if someone doesn't want to come out, they may be locked in the first room forever. So, we immediately knock on other doors and ask the people inside to come out.

Li Lei appeared after that.

It is precisely because of this that he also succeeded and implanted two thinking inertias into us as soon as he appeared.

First: His appearance was actually caused by us. If we don’t knock on the door, he will not come out.

Second: He is actually a weak man. The person who was locked up with him died. He was scared out of fear. He was young, had poor physical fitness, was afraid of death and needed help.

In fact... there was no one in his room, and he was the only one from beginning to end.

He just hid behind the door, waiting for us to call him out.

In fact, if we don’t call him out, he will come out by himself before the countdown ends.

And we will also remind us... It is because we did not call others out that those people were locked in forever, so as to implant the emotion of "self-blame" into our hearts...

In fact...
