Several people returned to the police station. Chen Bai and Dabinzi were about to go to the scene where the fire had been caught.

"By the way, Shan Tong has a strong antisocial personality and gets out his information as soon as possible. This kind of person is either unhappy in his original family, or has the shadow of childhood or adolescence. If he finds the reasons that stimulate him to be mentally perverted, he can catch him."

After saying that, Chen Bai took Da Binzi away.

"Why is the police coming again? Isn't this all over?"

Since Dabinzi and Chen Bai got off the bus, people around him began to talk.

"Comrade Police, do you come here one by one, and do we still have to do our business? We have suffered such great losses. We are not allowed to redecorate it now. What do you want to do?"

A man in his forties stood in front of Chen Bai, with one hand on his hips and one hand holding a can of beer in the other.

"I understand your difficulties very much, but we now suspect that this fire may be arson, as long as we investigate clearly..."

"Don't talk nonsense to me. What does this have to do with me? But if you said that person is really going to pay me some money? I won't have to pay myself. Also, you can see that not only me, but also the few companies next to me have been affected. Now we call Tiantian, and call Didi is not effective. Tell me, we are also small businessmen, what should we do!"

As soon as the man said this, several merchants affected by the incident surrounded him. Dabinzi couldn't resist it.

"Okay, shut up!"

Chen Bai shouted loudly and everyone stopped talking.

"I just suspect that someone in your house deliberately set fire, but there is no direct evidence now, but you said that if your house is really a fire caused by aging circuit, what should you do?"

"What should I do? Wait for compensation!"

The man didn't care at all, and Chen Bai slowly approached the man when he heard this.

"According to regulations, line inspection will be carried out once every six months. If the line is really aging, it means that you are perfunctory during the inspection and even have deceptive behavior. If it is really your own problem, the insurance company's compensation will not be obtained."

The man was shocked when he heard this, but Chen Bai walked directly into the store without caring about the man's surprise.

"Teacher Chen, is there any significance for investigation on the scene now?"

Dabinzi was a little puzzled. The fire, high-pressure water gun, and repeated firefighters entering and exiting. Is it really necessary to investigate such a scene?

"Remember, I'm just looking at the cause of the fire, and it's basically impossible to find any fingerprints and footprints from here."

The two came to the kitchen, which was the so-called fire point. Chen Bai saw that the cabinet next to the stove had been deformed, and the electric switch located at the entrance of the kitchen was the most serious. He could basically not see the original appearance clearly, so Chen Bai could only vaguely distinguish the cause of the fire from the ashes.

"What kind of power switch is this?"

Although the burning was a little deformed, it could still be seen vaguely. Chen Bai smiled and explained.

"This kind of electric switch is indeed very old. This kind of push-pull electric switch was not available many years ago. It seems that this is indeed an old store."

After Chen Bai said that, he turned around and suddenly fell forward without controlling his control, but fortunately, Chen Bai stabilized his body in time.

"Teacher Chen, are you okay?"

Dabinzi hurried forward, but was stopped by Chen Bai.

"Wait a moment!"

Chen Bai waved his hand, and Dabinzi immediately handed over gloves, evidence bag and tweezers. Chen Bai slowly picked up a black thing from the electric box and put it into the evidence bag.

"Give me one more!"

Dabinzi handed over another bag of evidence. Although Dabinzi didn't know what Chen Bai found, he saw the teacher's serious look and knew that the teacher must have an answer in his heart.

"Teacher Chen, what did you find?"

Chen Bai smiled slightly and handed the bag of evidence to Dabinzi.

"This is artificial arson, I know what's going on."

Looking at Chen Bai's excited look, Da Binzi was a little puzzled.

"Don't worry, you will naturally understand after we return to the police station."

The two left the restaurant, and the boss no longer dared to speak. After the two returned to the car, Dabinzi continued to ask.

"Teacher Chen, how did you know that the boss bought insurance?"

"Isn't this common sense? Don't you buy insurance when you open a store!"

When the two returned to the police station, Bai Hongwei had been waiting in the office for a long time.

"How is it? Have you found anything?"

Chen Bai smiled and signaled everyone to sit down first.

"I have read the information you sent me. Shan Tong grew up in a single-parent family since she was a child. Her mother disappeared directly after giving birth to him. His father has always regarded him as a burden. As a boy, he has lacked maternal love since childhood, and the only father who can rely on me regards himself as a drag. Children who grow up in such a family will naturally be distorted."

"Wait a moment!"

Kong Bingxuan suddenly spoke at this time, and everyone present looked at Kong Bingxuan.

"Actually, we have no obvious evidence to prove that Shan Tong is the murderer of these two arson cases you mentioned. If he is not the murderer, then we waste all the police force on him, and the real murderer is likely to be at large."

Chen Bai smiled and continued.

"Yes, we really have no evidence now. The murderer is very smart. He knows that the evidence of arson will not be left so easily, but I would also like to ask you to explain why Dan Tong disappeared after we found that supermarket. And how should he explain the arson tools at his home? No one would store gasoline ropes and cotton at home, it would be too easy to catch fire."

Kong Bingxuan had nothing to say for a moment, while Chen Bai opened the map on the computer.

"Actually, I don't have any evidence. When I saw the scene of the second fire, I thought about when he set the fire. So I asked someone to check the walls near the entire flower and bird market. Although it was difficult, fortunately there were results. We detected a set of clear fingerprints and footprints on the wall south of the flower and bird market. Combined with the things we brought from Shantong's home, we confirmed that the fingerprints were the same as Shantong."

Now, Kong Bingxuan finally had nothing to say. Bai Hongwei was also very surprised. After all, he didn't know when the Hengjian had done this job.

"Then I still have another question now. Will he set fire again if Shan Tong disappears?"

Chen Bai frowned and said with some concern.

"Yes, from the second fire he stood above and watched, he had now begun to enjoy the pleasure of setting fire. For him, arson has become a kind of enjoyment and he will never stop."

"Then what is his next goal?"

Chen Bai shook his head. He had just read a little bit of Shan Tong's information. It was still too early to analyze Shan Tong's psychology.

"Captain Bai, someone is looking for you!"

"Who is it?"

"It seems to say that you know the person you are looking for..."

The office door was opened, and a woman in her twenties walked in. Chen Bai recognized the woman as an employee working in the same supermarket with Shan.

"Is there anything to do with us?"

Kong Bingxuan quickly let the woman sit down, and Chen Bai spoke before the woman could speak.

"You are Shan Tong's girlfriend, right? No, you should call me ex-girlfriend now!"

Everyone was a little surprised, while the woman nodded helplessly.

"Yes, I've been dating Dantong, but we broke up very early. I feel that Dantong is a bit abnormal. He has a strong desire to control himself. Sometimes he even secretly looks through my phone halfway through sleep. He even quit his job and came to my workplace to apply for a job. Sometimes he gets angry if I just help the male customer checkout. I'm asked by him not to talk to men alone, and even if a man looks at me, he gets angry. And he often tells me that he will punish the sins of this world on behalf of God."

Chen Bai nodded and continued to ask.

"How much do you know about the previous things?"

The woman thought about it, shook her head and said.

"I only know that Shan Tong is from Jiangbei. He lived with his father when he was a child, but his father was not good to him, so I don't know anything else."

Chen Bai frowned. The most critical question now is that he must find the reason why Dan Tong is psychopathic. Why did he set fire so persistently?

"It seems that we are going to Jiangbei!"

Chen Bo's words surprised Bai Hongwei and others, but they also knew that this was probably the only way now.

"Don't go with me, just be with Dabinzi. I need someone around me who can show my ID at any time. Before that, you must not act rashly, especially don't issue a wanted order. Now, you can't be stimulated. If you stimulate him, it may cause greater consequences."

In this way, the two set out on the road to Jiangbei.

"Captain, do we just watch it and ignore it? Didn't we use a wanted warrant when we arrested Liu Zhuang? We also issued a wanted warrant when we arrested Wuchuan. Isn't there any problem? Why is it not possible this time? If we could catch Shan Tong earlier, we could stop him earlier. Last time he set fire to an empty market, what should he do if he ignited the natural gas pipeline next time?"

Bai Hongwei was also in trouble at this time. Kong Bingxuan said it was right. Although Chen Bai had already emphasized the danger of Shan Tong, if he really took advantage of this time to commit the crime again and cause casualties, he would definitely regret it. But what Chen Bai said was not unreasonable. If it was stimulated, Shan Tong would not know what he would do.

"No, we'll talk about it when Chen Bai comes back. I believe he will have a good idea."

Jiangbei is far away, and Chen Bai and Dabinzi have been traveling for almost a day before they arrive in Jiangbei. The place where Shan Tong was born was a small village in the mountains of Jiangbei.

"Uncle, do you still have an impression of this person?"

When he arrived at the entrance of the village, Chen Bai took out a photo and asked the old man sitting at the entrance of the village to enjoy the cool air. The old man didn't react much when he saw the photo, and he didn't even say anything. However, Chen Bai saw that the old man had a different reaction when he saw the man's photo. Chen Bai understood that it was not that the old man didn't know him, but he was just unwilling to say it.

"Old man, do you know this person? I'm very anxious now to find him."

Even Dabinzi could see that the old man was wrong, but Chen Bai stopped him just about to say something.

"Old man, Shan Tong is very famous in your village, right? I heard that he has always been a good boy, but now I have to find him."

The old man still didn't say anything, and Chen Bai didn't say anything, but just sat directly beside the old man.

"A child who has lost his mother since he was a child and was regarded as a burden by his father must have lived a hard life, right? Everyone is from the village, so he naturally takes care of him more, and he does not disappoint his hopes. He walked out of this small village and out of this cage that most people cannot get out of in their entire lives. Shan Tong carries the high hopes of your entire village, but he has never come back since he left here, right? Although you are very nice to him, this place brings Shan Tong only endless fear."

Chen Bai pulled out a cigarette and lit it, and handed it to the old man another one. The old man waved his hand and took out a cigarette pipe from behind and lit it with his trembling hands.

"Shan Tong is a good child, his mother is not a thing! Within three days of giving birth, there was no one left. Shan Tong's father is an ordinary farmer. He has never studied and doesn't know a few words. He thinks that he can live a good life by marrying his wife and having a son. But who knows that the woman disappeared after taking all the savings of the Shan family. Shan Chenggong is also a son who is not sure whether he is a bloodline of the Shan family. Shan Chenggong is a miserable person. He only knows how to farm but not how to take care of the children. Moreover, after that woman left, Shan Chenggong didn't even go to farm. She hides at home and drinks all day long, beats the children when she gets drunk, and occasionally sells the things from the family to buy wine when she is awake. It is not easy for Shan Tong to grow up so old!"

Chen Bai nodded, and then the two went to see the old house of the Shan family, but the owner had already changed more than ten years ago. Da Binzi looked at Chen Bai staring at the old house of the Shan family without saying a word, and asked anxiously.

"Teacher Chen, what should we do now?"

Dabinzi was a little anxious because there was no clear clue yet. If Dan Tong took advantage of this time to set fire again, the consequences would be unimaginable.

"Don't worry, he won't do it now. Let's go to his elementary school tomorrow!"

Early the next morning, Dabinzi and Chen Bai found Shantong's primary school. Although it was just a primary school in the town, they retained the information of the students that year.

"Shan Tong? Of course I have an impression of it. This kid is really an alternative!"

The vice principal wearing glasses directly used the word alternative, which surprised Chen Bai a little.

"You said this kid is good at studying, but fighting and destroying school public property are all vividly reflected in this kid. But you said that this kid is good at studying, so I can't punish him. But until he was in the second year of junior high school, that happened a bit too big."
