There are risks in eating melons, so be careful when watching the excitement.

This teacher who was eager to eat the melon came outside the crowd and couldn't wait to squeeze in. He didn't even understand the situation. When he saw the open space, he wanted to seize it and eat the melon, but he didn't expect that the place was empty.

There must be a reason why it is empty.

However, after the teacher's foot was pierced, all the teachers who knew something about the law thought of a serious problem.

Who placed this nail? The nature of this injury immediately changed. The police were suspicious that this was a criminal case!

All the teachers in the school were almost gathered here. Lu Feng was too embarrassed to come out to see people in this special situation. There were also a few people who had other things to do and didn't know or couldn't make it.

The person who placed the nails was most likely among these people.

According to the theory of criminal psychology, if the person who commits the crime is in this group, he will try to blend in with the group with more people to hide himself, and he will also like to return to the scene to watch to satisfy his perverted desire to commit the crime.

Heart needs.

This is the principle that Yu Fei told Ding Taotao. After Ding Taotao remembered it, she started observing the crowd to see if she could find the perpetrator through his face.

Because the other party's mental state was obviously different from the others, and someone was even injured at this moment. Yu Fei also speculated that this was a woman. If her psychological quality was average, she would most likely be panicked and expose her flaws.

However, Ding Taotao had been observing for a long time, but could not find any suspicious persons, because everyone had various expressions, and most people's eyesight was not that strong.

Many female teachers showed frightened expressions when they saw this bloody scene. After all, many of them may have never seen such a bloody scene in their lives, so the perpetrators were hiding in it, and it was difficult to judge when they showed such expressions.

There are also those who are huddled together to save people, with anxious, panic and other emotions on their faces. After all, they are ordinary teachers who usually only see children fighting, so it is understandable that they show such expressions.

Some people started calling the police, some called for an ambulance, and others looked for emergency medical kits to help the injured people stop bleeding before the ambulance arrived. The scene was not an ordinary chaos.

Ding Taotao stood there and was a little at a loss. She seemed to be unable to help, and she was a little panicked. At this moment, the only thing that came to her mind was Yu Fei, because now Yu Fei has become her biggest support, and she can't help her.

When you know what to do, you must think of Yu Fei immediately.

Ding Taotao hurriedly returned to the car, found her cell phone, and called Yu Fei.

After Yu Fei listened to Ding Taotao's description, he told Ding Taotao not to panic, but to wait for the police to arrive and let the police investigate. Finally, he specifically reminded Ding Taotao that when the police asked, she could just say she didn't know anything.

Don't bring up anything about Lu Feng, let alone Yu Fei's judgment. If you really want to say something, he will help Ding Taotao when Yu Fei comes.

After the explanation, Yu Fei rode Bai Qilin and rushed to the school. Originally, Yu Fei and the others did not plan to call the police. They planned to find out the guy behind the scenes. Unexpectedly, someone was obviously injured because of this. The police would inevitably intervene in this matter.

Already.

When Yu Fei rushed to the school, he met the injured teacher at the school gate. Others bandaged the punctured foot with gauze, but because the technique was unprofessional, it could not stop the bleeding at all, so the gauze was

It was soaked in blood and looked even more terrifying.

The teacher was carried on a simple stretcher and kept screaming in pain. The others stood aside nervously, looking in the direction of the county seat, waiting for the ambulance to arrive.

"Give me the gauze, your bandaging method is wrong and it won't stop the bleeding at all!"

Remain

Fei walked over and said directly, "This teacher is innocent, but he just suffered an unreasonable disaster."

Moreover, the injured person was a male teacher, and the injury was so serious. Yu Fei could rule out the suspicion that this was a trick, so there was no harm in helping this person to prevent him from losing too much blood.

In his spare time, Yu Fei also read some books on life-saving knowledge. On the one hand, he could handle accidents easily on his own, and on the other hand, his own ability to save people could also be covered up with some simple medical skills.

The teacher who heard Yu Fei talking recognized Yu Fei and felt that a big man like Yu Fei would not talk nonsense or show off his talent, so he immediately handed Yu Fei gauze.

Yu Fei quickly used the gauze as a rope and tied a position on the injured person's leg. If tied at this position, the blood flow rate of the arteries can be reduced, so that the amount of blood loss can be well controlled. Otherwise, excessive blood loss will lead to serious injuries.

Otherwise, it will damage the fundamentals of the body, or even kill people!

After the bandage was finished, Yu Fei wiped the blood on his hands with the remaining gauze and walked into the campus to find Ding Taotao, who he had arranged to wait for him.

Ding Taotao waited anxiously by the car. When she saw Yu Fei from a distance, she, who had been walking back and forth on the same spot, immediately stopped. The backbone came, and she was no longer so panicked.

"Are you OK?"

Yu Fei quickly walked over and asked.

"I'm fine. It's just that both front tires were punctured and a teacher was injured. Did you meet him at the door?"

Ding Taotao shook her head. She didn't have any problems herself. She just got more and more angry when she thought about this perpetrator.

When the other party placed the iron nails, he should have thought that this thing could not only puncture the tires, but also the soles of people's feet, but this guy still did it, and his evil intentions were evident!

Now that Ding Taotao sees someone being implicated because of her, and then thinks about the other person's abominable behavior, she feels chills on her back. This time she can't forgive the other person no matter what.

"The other party avoided the surveillance in our car?"

Yu Fei looked at the nails on the ground, and then looked around to make sure that this was definitely not the place Ding Taotao chose to park, and he understood how cunning the other party was.

This person chose a different method every time. Yu Fei's thinking actually failed to keep up with the other party, and once again he was succeeded by the other party.

"Well, you can't take any pictures from here."

Ding Taotao nodded. She had just studied the surveillance in the car and found no valuable clues.

"The end of each nail is no longer very sharp. This is because the opponent was not strong enough and used other tools to drive the nail into the ground backwards, so the end was flattened!"

"This kind of nail is very common and used in various projects. Although the other party's nail is unused, from the rust, it seems that it was a nail purchased a long time ago. There are no clues through the purchase of the nail!

"

"But an ordinary person, or a female teacher, would not repair the desk or stool by herself even if it was broken, let alone keep it around. She must have obtained it from somewhere else, so this nail is still a clue!"

Yu Feidan relied on nails and analyzed three points.

"Where do you think this nail came from?"

Ding Taotao asked curiously.

"Judging from the rust on the surface, it looks like it's a cold and damp place. I guess she won't move around too much to avoid exposing herself, so it should be inside a school."

Yu Fei made a judgment again.

"That's not easy to find either."

Ding Taotao frowned, she didn't even know where there were nails in the school.

And even if you know, in fact

It's useless. The village school has been relocated in the past few days, and many areas of the school have been cleaned. When the other party is packing up, no one will notice if they walk by or pick up a few nails.

Yu Fei frowned slightly, then slowly squatted down, put his nose against an untouched nail, filled his nose with spiritual energy, and raised his sense of smell to the extreme, smelling all the smell on the nail.

Inside the nasal cavity.

Ordinary people's sense of smell can only distinguish some relatively obvious smells, which is of little value as a reference unless the other party is too stupid and the exposed smell is too obvious.

But Yu Fei's enhanced sense of smell is comparable to that of hunting dogs, and may even exceed that of hunting dogs.

After smelling the nails, Yu Fei asked Ding Taotao to walk around with him.

With teacher Ding Taotao leading the way, there is almost no place in the school that Yu Fei cannot reach, unless it is some special archives or the teacher's dormitory.

Soon they arrived at the school's teaching building. At the top of a staircase, Yu Fei's nose twitched and he walked to the door of the storage room under the stairs.

Such storage rooms are separated by the corners under the stairs and are very suitable for storing some sundries.

"Will anyone enter this storage room these days?"

Yu Fei turned around and asked.

"Yes, the storage room in the teaching building mainly contains desks, chairs, benches and other teaching aids. With so many students from the village school joining here, it is natural to prepare these things and arrange some classrooms."

Ding Taotao nodded.

Yu Fei scratched his head, this was troublesome, thinking that he could be sure that the nail came from this storage room, so there must be a lot of people entering, and the surveillance around the teaching building was only one at the entrance of the corridor on each floor.

There is one on each side of the building, and there are many blind spots.

This storage room is on the first floor, and there must be a lot of people going up and down every day, so it is another layer of protection.

So how do you find the person who took the nails from here?

While Yu Fei was thinking about this problem, Ding Taotao's cell phone rang. It turned out that the police were here and asked Ding Taotao to come over and cooperate with the investigation.

Yu Fei and Ding Taotao went back. The police were also inspecting the scene. They also studied the nails. Their judgment was basically the same as Yu Fei's. The nails were smashed into the gap with a heavy object. The nails were purchased a long time ago. They could not interrogate by the place of purchase.

Come out the murderer.

The police don't have Yu Fei's perverted sense of smell. As for sending out police dogs to search for it, it doesn't make much sense. Police dogs can't track things brought through the air.

Therefore, the police focused on Ding Taotao in solving the case, but Ding Taotao did not know anything about it according to what Yu Fei said.

Because Yu Fei is worried that what Ding Taotao said is wrong and involves Lu Feng and Huang Hengtong, it will be troublesome. The two people's affairs will be involved in the investigation, and Yu Fei's donation to build the dormitory building may be exposed.

Once word gets out that he has not purchased his current house, and those villagers will sit there and ask for the price, it will be their own loss, at least several million will be lost!

Therefore, Yu Fei told the police that he could provide some clues, so he avoided some topics that could not be discussed and shared his analysis.

The person who told the police might have done this was a woman. Yu Fei told the reason, and the police agreed with it.

As for the motive for committing the crime, Yu Fei told the police that it might be out of envy and jealousy. The other party saw everything Ding Taotao had now and had a perverted mentality. Therefore, the police agreed with him that he did such a thing.

What Yu Fei said was well-founded and supported by evidence, which saved the police a lot of investigation time.
