"Now it's clear that someone has designed complex computer programs to kill people. If someone deliberately designed these programs, why kill them? What's the connection between them? One is a college student, the other is an auto parts engineer. "

Zhao Bofan and Mingzhu analyzed the current situation: "there are only two situations. First, the murderer killed people randomly and purposelessly. Second, there is a premeditated choice to kill. I prefer the second one, because the other party must know that I will investigate this case again. Otherwise, why would they cast the killing procedure in my family's website? This brings about a problem. I want to find out the relationship between the dead. "

"Husband, there's a party tonight. Please clean up and we'll start later." Zhang Xia talks to her bedroom as soon as she enters the door.

There was a complete silence at home, and Zhang Xia pushed the door open doubtfully. In the room, her husband Qian Hao collapsed in front of the computer chair, his face full of white viscous liquid.

Wang Feng calls Zhao Bofan and tells him that another person died just now. It's a computer program!

Because Mingzhu knows about computers, Zhao Bofan takes Mingzhu to the scene. Just out of the lab, a gray haired, skinny old man is not far away now, looking at Wu Mingzhu.

Mingzhu was surprised to see the old man when she went out, but she was afraid that Zhao Bofan would see something unusual and quickly returned to normal.

Mingzhu said to Zhao Bofan, "you go first. I'll deal with this."

Zhao Bofan took a look at the old man and Wu Mingzhu, then left.

"I want to see your father," the old man said without expression

"You know, he just came out of the mental hospital, and he's been there for 20 years. It's really not a good time to see you. "

"Two months and twenty years to go. I think I know better than you."

Mingzhu looked at the old man seriously: "why do you want to see him? Did you blame him for the accident? I'm very sad that something like that happened, but even if you see my father, your daughter will still come back. "

The old man said with a gloomy face, "this is between your father and me. It has nothing to do with you."

Pearl looked at the old man, "sorry, I can't help you. He's in an unstable mood. I can't let you meet. "

When the Pearl left the old man, he stood in the same place and watched the Pearl leave without expression.

Around the corner, Zhao Bofan stood in the same place, looking at the Pearl with a complicated expression.

Zhao Bofan said straight to the point: "I know who the old man was just now. Twenty years ago, her daughter became an intern of Professor Wu. Because of an accident, she died here. "

The Pearl's eyes are full of alert looking at Zhao Bofan. "What do you want to say?"

Zhao Bofan saw Mingzhu's expression changed obviously, but he still said: "she is a poor mother. I think Professor Wu has the ability to be responsible for her mistakes."

Mingzhu stares at Zhao Bofan's face. After a few seconds, she walks to the laboratory without turning her head.

Zhao Bofan sighed and went to the laboratory. In the laboratory, the Pearl sits on the most side chair. As soon as Professor Wu sees Zhao Bofan coming in, he immediately steps forward.

"Boy. I've made it clear that it's software. It must be a compound stimulus of vision and hearing. When a person clicks on it to watch it, he will expand the electric pulse of the human brain. After brain stimulation, he will have hallucinations, just like a virus in the human brain! "

Ma Hao came to the laboratory and said to Zhao Bofan, "I found out the connection between the dead. The first one is Li Ke. Li Ke is Zhang Han's classmate. The one who died just now is Qian Hao. He is Zhang Han's stepfather. Most importantly, Wang Yang is the former leader of Zhang Han's father! "

Zhao Bofan said in surprise: "the suspect is locked. It must be Zhang Han's father."

"I think so, too. But now Zhang Jun can't find anyone. "

Zhao Bofan mysterious smile, that can only let his son as a breakthrough.

In the interrogation room, Zhang Han sat alone, clasping his hands.

Ma Hao looked at Zhao Bofan: "before we came, team Wang had sent someone to communicate with the child, but he just didn't say a word."

Zhao Bofan looks at Zhang Han in the glass behind the interrogation room. He chuckled: "you see his stubborn appearance. He just wants to defend his father."

Zhao Bofan enters the interrogation room.

"Hi, we meet again!"

Zhang Han looked up at Zhao Bofan and continued to lower his head.

"How long ago was the last time you saw your father?"

Zhang Han heard Zhao Bofan ask him questions, had been silent, he said without hesitation: "about three weeks ago."

Ma Hao outside the interrogation room smiles, thinking that Zhao Bofan is really a good boy.

Zhao Bofan snapped the victim's picture on the table. Aggressive asked: "your father has killed three people! One is your classmate! One is his leadership! One is your stepfather! How many more people are you going to die? "

Zhang Han roared with a red face: "my father is not like that! You just don't know him! "

Zhao Bofan is familiar with psychology. Even if he is shy and weak, he will become strong when he is faced with protecting his important people. Just like hens will bravely protect their chicks when facing snakes. Zhang Han's mental pressure has been very big, all give him a fire, he will light. Zhao Bofan decided to change his mindHe said to Zhang Han, "well, you have finished the investigation and can go."

The argument at the door of the laboratory just now was not pleasant. Mingzhu stood in the interrogation room and didn't say a word to Zhao Bofan. Zhao Bofan out of the interrogation room, pearl seriously asked: "you just let him go?"

Zhao Bofan easily said: "the case has been solved, it depends on how to put a long line to catch big fish."

Zhang Han went to the door of the police station, took out wechat and asked didi for a ride. Soon after, a Zhang Han got on a white Honda. Zhao Bofan pushed the Pearl, "Hey, let's go."

Mingzhu asked suspiciously, "don't you want to talk to him? You think he's going to find his dad now? He's not stupid. "

Zhao Bofan looked at the Pearl's face for a long time and said with a smile: "he is just a child, a child who loves his father. Trust me

White Honda drives to an old neighborhood. Zhao Bofan also stopped 20 meters after the car stopped. After getting off, Zhang Han went into the corridor in front of him and went to the basement.

"You wait for me in the car!" Zhao Bofan orders that he doesn't want the Pearl to come in, because the other party is also a dangerous person.

When he reached the door of the basement, Zhao Bofan heard the quarrel between Zhang Han and his father Zhang Jun.

"So you really killed them? I'm so disappointed in you. " Zhao Bofan heard inside Zhang Han emotional responsibility of his father.

"You don't know what they did to me! Son, they all betrayed me. "

Zhao Bofan slowly twists the basement door at the door. In an instant, the harsh alarm sounded. "Damn it Zhao Bofan cursed in his heart, and the other party set up a trigger alarm at the door. I was too careless.

All the computers in the basement look like Zhang Bofan at the door.
