Dabinzi was very excited when he heard the vice principal say this. He could catch him as long as he knew what happened to Shan Tong when he was a child. Chen Bai's smile on his face became stronger, but his next words surprised him.

"Vice Principal, it would be even better if you told us directly where he was now."

The vice principal was obviously stunned when he heard this and said immediately.

"How could I know this? Shan Tong hasn't come back for a long time. How do I know where he is?"

Although the vice principal concealed it very well, Chen Bai still discovered the clues.

"Why are you so nervous? Even if Shan Tong really made a crime, it has nothing to do with you, but why are you so nervous?"

After Chen Bai said this, Dabinzi felt something was wrong. The deputy principal was indeed a little nervous.

"I, I don't, I just feel a little nervous when I suddenly see the police coming to my door."

"No, what are you nervous if you didn't do anything wrong?"

Chen Bo can now be sure that the vice principal either knows where Shan Tong is or has met Shan Tong recently.

"It is a serious crime to not report it because you are a vice principal who wants to set an example for the students."

Listening to Chen Bai's words, the man finally couldn't hold back.

"Yes, I have met Shan Tong recently. It was two days ago that Shan Tong suddenly came to me and said he wanted to borrow some money to find his mother. I knew that Shan Tong's mother disappeared a few days after he was born. Why did Shan Tong suddenly look for his mother? But Shan Tong has always been a good child, so I didn't ask more questions after that. Add Shan Tong to borrow only one thousand yuan, so I didn't ask more questions."

Chen Bai looked at the vice principal and confirmed that he was not lying.

"Then did he tell you where to go?"

"No, he didn't say much, I didn't ask."

Chen Bai nodded and asked.

"Okay, let's continue talking about what ridiculous things this Dan Tong did in the second year of junior high school?"

The vice principal took a deep breath and suddenly changed his tone.

"Actually, the truth of this matter is no longer verified. This is also the secret of our entire village. Because Shan Tong's father no longer cares about his study and life, the child ate a hundred-store meal in the village. I remember that it was very hot that day. After Shan Tong finished the meal, he went home to get things and then went to class. Later, their house caught fire. Of course, his father had nothing to do because he was drinking outside, but later he was rumored that it was the fire that Shan Tong set, but after all, there was no evidence, so the matter was left alone."

On the way back, Dabinzi asked in confusion.

"Teacher Chen, what should we do now?"

Although I gained a lot this time, there were actually no clear clues. Dan Tong was still outside, so I don’t know what extraordinary things he would do next time.

"Let me think about it, I always feel like something has fallen."

Chen Bai closed his eyes and pondered, and the case was turning around in his mind.

"How is the scene?"

The thing that worried Bai Hongwei the most was still happening. Just at five o'clock this morning, a fire broke out in the second dormitory of Anyang Chemical Factory. This time, when the firefighters put out the fire, they carried out three bodies.

"The fire has been put out, but I suggest you better wait first. There is a risk of rekindling at the fire site at any time. Let us go in first and check it carefully."

"Okay, thank you for your hard work!"

Kong Bingxuan looked at the three bodies on the ground and punched the police car next to him.

"Captain, look at the current situation. It was because Chen Bo did not allow us to arrest people. If we arrested people as soon as we got the evidence, we would not have been like this at all."

Bai Hongwei didn't say anything, but he was even more worried about the fire if it was really done by Shan Tong, what else would he do next? Will it be too much each time?

"Captain, I really don't understand why you have to listen to Chen Bai. He is not a policeman at all. What can a genius understand? In his eyes, everything can be guessed, but now he guessed wrongly, but he won't feel any guilt in his heart."

"Okay, are you done? From the beginning of the case to now, he helped us find the murderer. Without him, the first two fires can only be dealt with by accident. Think about what you did before talking about others."

Kong Bingxuan was really angry when he looked at Bai Hongwei, lowered his head and stopped talking.

"How is it? Have you found anything?"

"I can only tell you that these three people were burned to death. I must go back and tell you the others. However, according to my preliminary autopsy, there is no other injury on these three people, so there is no need to be knocked out or burned after being beaten to death."

It was eight o'clock in the morning, and the firefighters finally cleaned up the scene. Bai Hongwei and others entered the scene. The dormitory on the third floor was on fire, but after they observed the scene, they found nothing.

"What do you think?"

Bai Hongwei looked at the fire brigade behind him and asked, after these contacts, they gradually became familiar with each other.

"The cause of the fire is very simple. There are mosquito coils on the windowsill. The air-conditioned wind blows the curtains. The cotton curtains are lit by the mosquito coils, causing a big fire. The few people in the dormitory are sleeping soundly, and no one realizes that the fire is on. By the time they find out, it is too late."

Bai Hongwei frowned. It was indeed the case from the scene, but he knew that it was very likely that it was done by Shan Tong again.

"What's going on?"

Chen Bai's voice sounded from behind. Bai Hongwei turned his head and saw Chen Bai coming, and quickly waved his hand to let Chen Bai come in.

"Okay, I already know where to find the Dantong."

After Chen Bai finished speaking, he put on his gloves and started to investigate the scene.

"No, this is not an accident, it's artificial."

Chen Bai picked up the mosquito coil plate on the ground, looked at the traces on the windowsill, and then looked at the traces around the windowsill.

"This is just a simple ignition device. Here is a mosquito coil plate and then a match is placed on the mosquito coil. The curtains are very long. Then the curtains are placed on the matches. When the mosquito coils burn here, they will light the matches, and the matches will light the curtains."

Chen Bai stood up, clapped his hands and asked.

"Go and check the surveillance here. This device is not clever, but the person who arranges this mechanism must be outsiders."

"Outsiders? Can they arrange such institutions in the dormitory?"

Kong Bingxuan finally got the opportunity to speak, but Chen Bai smiled and said.

"It's very simple. If it was really done by the people in this room, then the people in this room wouldn't be dead."

But when everyone returned to the office, Kong Bingxuan asked disdainfully.

"So what if you look at the scene? Can you find where Shan Tong is? You didn't let us arrest him, but now he has done another case. What should you do now!"

Chen Bai smiled and took out a file bag from his body.

"According to my investigation, Shan Tong's mother disappeared after giving birth to Shan Tong, but after my investigation, the identity of this woman has been found by me."

As he said that, Chen Bai took out a stack of information from his file bag.

"Chen Fang, born in 1966, was involved in society after graduating from elementary school, and later went to a marriage fraud. Now this woman is in Binhai City, and I have taken people to arrest people. Dan Tong's final goal must be to kill his mother and take revenge."

On the other side, a man hid behind a telephone pole with a hat and mask, and the man's eyes flashed with a resentful light.

"Fire can purify everything, let me end the sins in this world!"

After the man finished speaking, he slowly walked towards the apartment in the distance.

"Bang bang bang!"

"Who?"

"express delivery!"

The moment the door was opened, the man raised the electric baton in his hand, but the next second the man was kicked out.

"superior!"

Bai Hongwei and others in the distance watched Shan Tong being taken out, and they couldn't help but admire her. Chen Baizhen caught Shan Tong with his criminal psychology.

"Take him back first, let's go eat something! We haven't had a good meal for so many days. To be honest, I've been vomiting in the past few days. I've never eaten so much instant noodles in my life."

Chen Bai started the car, and the three people in the car stopped talking. After searching for evidence for so long, it was not as good as Chen Bai's reasoning.

"you...."

"I want to ask how I know Shan Tong's actions?"

Chen Bai opened the car window and pulled out a cigarette to light it. The smoke floated out with the car window, and Bai Hongwei nodded.

"It's actually very simple. Serial murderers have three characteristics: arson, bedwetting, and animal abuse. I found a lot of things when I went to Jiangbei. Dan Tong's house was too hot when he was a child. I believe this is not a coincidence. Although the house of Shan Tong's house has been sold to others, I can see that the traces of the fire are still there. The fire is not small. Jia was originally the warmest harbor, but Jia is hell for Shan Tong. There are many paintings in Shan Tong's house. Although the paintings are messy, if you look closely, you will see that Shan Tong painted the scene of his three arson cases. In the middle of his house, a woman was tied to a cross and was stolen, and that woman was Shan Tong's own mother."

It was already evening when everyone returned to the police station after dinner. Shan Tong was locked in the interrogation room. When Chen Bai and Bai Hongwei entered, Shan Tong was already a little impatient.

"What? Finally I can't help it?"

Unexpectedly, before Chen Bai and Bai Hongwei spoke, Shan Tong actually spoke first.

"We can't help it? Even if you don't speak, we can condemn you."

Shan Tong smiled disdainfully, as if he didn't care about such things at all.

"You are wrong. I am just. I punish the sins in this world. But if you catch me, the world will soon be filled with sin again."

Chen Bai smiled and took out a photo from the file bag.

"No matter how you deny it, this woman is your mother. I know you only hate your mother, but this woman is your mother no matter what. Now she is also in the police station. If you need it, I can arrange for you to meet."

"No, she is not my mother, she is not worthy."

Shan Tong suddenly became very excited, Chen Bai smiled and knew that Shan Tong could no longer calm down.
