"Are you taking a closer look and do you see anything different?"

Han Zheng looked at it very seriously for a long time, and after holding it for a long time, he said: "You did this question wrong!" ”

Wang Yu took the book and pointed to the English words circled on it and said: "This is an English word, and when you connect it, it means not to say it, do you understand?" ”

"Why don't you let us say, then the teacher will be arrested?"

"Your IQ can only go so far, and it is estimated that elementary school students are better than you."

Wang Yu didn't bother to explain to him, and continued to walk forward, Han Zheng kept asking questions behind him.

Back at home, Wang Yu's parents didn't come home that night because of work, so there were only the two of them, and Han Zheng kept pestering Wang Yu.

"I don't know why, since the teachers all say that, let's just keep our mouths shut."

"The teacher obviously helped us, even if it was to pay for the medical expenses, the big deal was that I confessed to my parents, just ask them to get a point, why should I be so persistent."

"Why are you so persistent, have you finished your homework?"

Wang Yu finally interrupted his question, and his ears instantly fell silent.

Sitting by the window and looking at the big trees outside, making a rustling sound, Wang Yu also thought about the question that Han Zheng said, and recalled He Xiong who he saw in the interrogation room.

Han Zheng doesn't learn for a day, but he doesn't think about such problems, but Wang Yu usually likes to watch some detective novels and movies, so from the feeling of it, He Xiong has a secret that no one knows.

"Li Sheng, I found it, these people are a middle-aged man, a young woman, and a teenager."

"Did you find a body?"

Li He shook his head and said, I am also waiting for the results of the sample to connect these things.

"Team Li, He Xiong is still two hours away from being released."

When Li He heard the news, he began to pace anxiously around the room, trying to think of a way to detain He Xiong, the only place where he could guarantee that he would not do anything to the corpse.

But now only new clues can justify He Xiong to stay here.

Watching the clock disappear minute by minute, all of us who are doing it are anxious.

I rushed over to urge my colleagues in the sample room, but they told me, "It will take at least three hours for the results of this test." ”

I quickly calculated the time in my head, still an hour slower than the time he left.

It seems that this time, there is nothing we can do to prevent this from happening.

Forty-eight hours have passed, He Xiong was acquitted, we only guessed before, although there is his confession, but when he said the whole thing, he once again repented, so all the time has been wasted by him.

The moment the handcuffs were opened, He Xiong moved his wrists, perhaps with an arrogant laugh in his heart, but he left as expressionless as possible.

Li He unwillingly ran to investigate the whereabouts of the body, I stood at the door and watched his back in the distance, and the moment he went out again, he seemed to glance at the police station, and then buried his head in his clothes, curled up and left.

I'll go back and stay in the sample room, hoping that this time there will be good news again.

The first place He Xiong went to when he left the police station was Wang Yu's house, and he watched downstairs that the lights had been turned off, so he didn't go up to disturb him.

However, on the second day, he did not choose to go to work, but chose to take three days off.

Then he spent three days to give himself a total relaxation.

"You said that we should go to see the teacher again, after all, it is for us that we will become what we are now."

Although Han Zheng said this very quietly, he was still covered by Wang Yu's mouth.

He took him back to his room, covered his head with a quilt and said, "Someone from the house has been here during the day." ”

Han Zheng was slightly surprised and said, "How do you know? Aren't we at school during the day? Besides, isn't it normal for your parents to come back? ”

Wang Yu waved his hand and said: "It's not my parents, I know their daily trajectory, and when I was leaving, I deliberately put the broom at the door, but when I came back, I didn't see the broom fall to the ground." ”

"If my parents come back and encounter such a scene, they will definitely put the broom aside, and then when they come back at night, they will scold me, you can also see it, this is a very obvious thing."

Under Wang Yu's analysis, Han Zheng listened to it with relish, and even felt that he made sense.

So under his wave of analysis, Han Zheng completely fell and became his fan brother, and he believed that this family had listening equipment.

On his first day, He Xiong chose to travel by car and went to the nearby suburbs, perhaps he already knew that the police would be watching him, so everywhere he went, there were surveillance equipment.

Then I stayed in a hotel in the suburbs for another night, and in the middle of the night I went to a nearby bar to relax, and I didn't choose to go back until the early hours of the morning.

If the hotel staff hadn't woken him up, maybe he would have stayed there for two days and two nights.

After being woken up, he went to a nearby noodle restaurant, ate his first meal, and watched the time re-plan the route.

Then he went to the playground, he played with almost all the equipment, and when this body revealed fatigue, he chose to go home and rest for a good night.

On the third day, I woke up to noon, ordered takeout, spent a limited afternoon at home, and prepared for the next day's class at night.

Li He still hasn't found any corpses, but I've found new clues here.

"Li He, all the samples have been extracted, and we have found a chemical element in it."

"Chemical Elements, Chemistry Teacher!"

It was as if he had seen the sun, and his face was filled with a warm smile.

But now it can only be said to be a coincidence, and it cannot be directly convicted, I think Li He also knows this, but it is much better than we have been looking for so long and have no clues at all.

"So what should we do next? Is it to be detained first, or to ......"

After pondering, Li He said, "Is it possible to accurately determine the chemical composition now?" ”

I nodded, "Let's go to the school first, count and see if there is anything missing, and then take all the evidence and go to He Xiong." ”

Wang Yu and Han Zheng knew that the teacher was back for class today, so they took the initiative to come to the school and waited for the teacher's arrival.

At the same time, the school leaders also announced the reason for He Xiong's absence from class in the past few days during recess.

Although there are still many doubts, Wang Yu and Han Zheng are excited, which means that he does not have to go to prison.

Li He and I showed up at the school again, and we went straight to the principal, but this time it didn't seem to go as smoothly as the last time.

"Officer Li, it's not that I don't want to, we also cooperated with you last time, but now the junior high school students are about to take the high school entrance examination, and there are only a few chemistry teachers, what do you say you want me to do?"

"I can understand, but if he is really a murderer, have you considered the reputation of your school, the principal?"

After constant communication, we all hoped that the principal would accept this request, but in the end we started to fail.

Standing at the school gate, Li He refused to take this step for a long time, "What are you waiting for?" ”

Glancing back at the school, he sighed and said, "It's just one step away, I really don't know where the difference is, and I'm about to see the answer, and I'm sinking into the sea again." ”

I can understand this emotion, but we can only choose to face it, and other than that, we need to follow the targeted evidence.

"You say, Mr. He, why do you want to take a leave of absence? Why didn't he come straight to class? ”

This sentence happened to be heard by us, and Li He glanced at me and walked towards the principal's office, and I followed behind him.

"Headmaster, why are you ......?"

It was indeed a bit reckless to go in without knocking on the door, but when I saw He Xiong sitting in the principal's office, even I had to wonder if there was some kind of secret hidden between them.

"Teacher He, you better go back to class first!"

"Wait a minute, we just have a few questions to ask, you guys!"

He Xiong's reaction was not too intense, but the principal was not very calm to stop us, "This is the school, even if you are a policeman, you must abide by the rules and regulations of the school!" ”
