This question is very sharp.

Not only Guan Hongshan, but even Lu Hai noticed something unusual.

Wu Sin's footsteps paused: "I always feel that he doesn't seem to be afraid of us much. ”

"Everyone else was a little nervous when they saw us, but it felt like Lu Zhen had dealt with the police? I rarely see people like that. ”

This is not only about Wu Sin himself, but also about other people.

Several people looked at Chu Yin in unison, as if they were all waiting for Chu Yin to give an answer or explanation.

After all, they are really not very proficient in psychology.

Chu Yin stood firm and said categorically: "There is no problem. ”

"In psychology, there is a disease called mental cleanliness, and his performance is normal, otherwise he would not have come here to be a school doctor."

Wu Sin was puzzled: "Spiritual cleanliness? ”

Chu Yin explained simply: "It's just that he is very resistant to this thing in his heart, so he can't do such a thing." ”

"Here's an example."

"He said he didn't want to go to the hospital because he hated the cheating environment of the hospital, but maybe it wasn't because of disgust, but because of mental cleanliness."

"Medically speaking, there is nothing wrong with it, and his reaction is normal."

Hearing this, Wu Sin suddenly realized.

"No wonder, it's a pity, he has such a high education, but it's a pity to have such a problem."

A few people continued to walk forward, but Chu Yin was a little behind.

For some reason, the feeling of uneasiness in my heart is gradually spreading.

Just as Chu Yin was thinking, a crisp mobile phone ringtone interrupted her thoughts.

Guan Hongshan picked up the phone: "Qin Ming? How's it going? ”

On the other side of the phone, Qin Ming's voice sounded anxious: "Guan Team, I have investigated." ”

"These places of serious injury, although they are not fatal, are getting more and more intense."

"If the development is allowed and the murderer is not caught, then the next one is very likely to threaten the life of the next victim!"

"He's supposed to be manic, but I can't tell."

Qin Ming's words made the atmosphere present instantly freeze.

Guan Hongshan frowned and replied in a low voice: "I know, you continue to investigate." ”

After hanging up the phone, Guan Hongshan turned his head to look at Chu Yin, speaking quickly.

"Miss Chu, we may need your help."

There is no doubt that the murderer must have been a person with great psychological problems.

It can even be said that if a patient with mental illness really dies, the consequences will be unimaginable.

Guan Hongshan briefly told Chu Yin about the matter, and said after a while: "Miss Chu, Qin Ming judged that the murderer had mania and could not control his behavior. ”

"There's also a huge psychological problem, and it's fun to hurt people. Then over time"

Chu Yin's face was not very good-looking: "As time goes by, it will evolve from hurting people to killing people." ”

It has to be said that it is convenient to talk to people with high IQs.

Almost without Guan Hongshan's words, Chu Yin already knew the seriousness of the matter, and she immediately cooperated: "Okay, I know what to do." ”

In order to ensure Chu Yin's safety, Guan Hongshan took the initiative to say: "Let's go to the city bureau today, right?" There are places over there where you can rest. ”

Chu Yin nodded.

Inside the office of the city bureau.

Chu Yin didn't mean to rest when he came here, but took the initiative to ask Guan Hongshan for some information about this case.

Guan Hongshan is also not stingy and presents everything on the whiteboard.

"According to the information available now, the time of the first case was April 10."

"The second one was on April 20."

"The third one was on April 29."

"The next one happened on May 8."

"Time is getting shorter and shorter, and the means of hurting people are getting worse and worse, and what we have to do now is to catch the murderer as soon as possible."

"What does Miss Chu think about this?"

Chu Yin's opinion is very important, and it can even be said that it can clear the fog and give them a clear path.

"The murderer should have committed a corresponding crime before."

"At first, it may have been the slightest injury, but the victim didn't report it, so it was gone, but by the time I found it now, it was actually too late."

Wu Sin was surprised: "What do you mean?" Could it be that the first case did not occur on April 10? ”

"That's right." Chu Yin nodded and gave a clear reason for the analysis.

"Quite simply, a person's spirit cannot suddenly become like this, and psychologically, his behavior is symptomatic. It's just that at the beginning, it's not obvious, and when it's obvious, it's already a mistake. ”

"His condition is getting worse, and based on the day I was threatened, his mania has been shortened to two days."

"We don't have much time left, but we can force him to show up as long as we set up an ambush or lure within the range of his passing."

It is a little too unsafe to let people go to lure the murderer to appear.

Guan Hongshan and Lu Haiyi discussed and chose the safest method.

"Immediately notify the school and lock it down! No one is allowed to let it out! ”

The police were very efficient, and almost within half an hour, they had already sealed off the three schools where the accident occurred.

Of course, it also includes Jingbei University, where Jiang Bai is located.

In order to grasp the best clues!

Chu Yin elaborated on the victim's situation, and the more he said to the end, Chu Yin's tone suddenly paused.

"That's not right."

The sentence exploded like a small bomb: "The actions of the perpetrators involved these three schools, but strangely, nothing similar happened in other campuses. ”

"And"

"April 10th!"

Chu Yin suddenly remembered an important thing: "This year's school start time is late April, and there are no students at school on April 10!" ”

Chu Yin picked up a whiteboard marker and drew a circle on top of the first victim's name.

"Graduate student at Kyungpook University."

"So that means the murderer was in graduate school at the time?"

Soon!

They sorted out a basic piece of information.

"The killer was a man, in his mid-twenty-third year-olds, with a strong build, and free access to the three schools."

"Looks like we'll find it right away."

However, just said the sentence!

Lu Hai immediately denied: "No! ”

"This is most likely a blind spot left by the suspect!"

"Don't forget, it's only been three days since we took on this case!"

"It's impossible that the person who handled the case before didn't check the graduate school! If there is a problem, it must have been told to us a long time ago, and it will not wait for us to investigate! ”

Hearing this, the faces of several people changed a lot.

Wu Sin couldn't help but be shocked.

"Fog grass! Is it my delusion? I always feel like this case is being aimed at whom? ”
