Outside the door of the interrogation room of the Public Security Bureau, Sun Yu leaned against the wall with his arms folded, squinting proudly.

"Hurry in! Qin Chuan said that he will only talk to you." Xia Lan pushed Sun Yu impatiently, but Sun Yu didn't move at all.

Xia Lan took a helpless breath, "The seafood buffet is absolutely spot on!"

Everyone gets the stolen goods, and the police force can provide Qin Chuan with nothing to convict him. But not only Qin Chuan, but also the people in the police force are curious about how Sun Yu accurately positioned his position.

The most important thing is that the woman who was attacked at the scene was not the woman Qin Chuan had been in contact with in the past few days, but the cleaning lady of Qin Chuan's community.

Upon hearing the seafood buffet, Sun Yu nodded with satisfaction, turned around and opened the door of the interrogation room.

In the interrogation room, when he saw Sun Yu walking in, the depressed Qin Chuan immediately became energetic. If he hadn't been restrained by the interrogation chair, he would have rushed up to grab Sun Yu's collar and asked him how he knew.

After sitting down, Sun Yu smiled at Bao Youliang next to him, and then said to Qin Chuan: "I know you have questions to ask me, but the police also have questions to ask you. It's an equal exchange. If it doesn't work, I'll leave now."

Qin Chuan was able to convict him, so Sun Yu naturally had to assume a superior attitude. Only in this way could he completely defeat his defense.

After Qin Chuan nodded, Bao Youliang spoke, "Where is the body of your mother Jiang Linli?"

"There is a flower field 20 kilometers west of her home. The flower field belongs to her. I poured sulfuric acid near the burial site and sprinkled a layer of lime on it. Dogs will not find it for a long time."

After saying this, Qin Chuan couldn't wait to stare at Sun Yu, "How do you know that my partner is the cleaning lady in the building? Where is my flaw?"

Sun Yu shrugged, "Those are two questions. You have to explain clearly the process of killing Li Manyu."

Qin Chuan immediately cooperated and explained the process of killing Li Manyu, and also added the location of the tools he used to dispose of Li Manyu's body.

Sincerity is already there, it would be a bit too much if we don't help people clear up their doubts.

Sun Yu glanced at the one-way mirror on the side, "Let's talk about your flaws first! You asked one more question that day. You asked me how I knew about your relationship with Li Manyu. My understanding is that you didn't expect that we would meet.

Discovered you through Li Manyu.”

You are a forensic doctor, and you must be very organized in your work, so you must have a very detailed plan when committing a crime. You deliberately left us DNA and left traces of Li Manyu's affair with others. This is what you want us to know. Then your

The question illustrates another thing. In your plan, we should not discover you through Li Manyu.

So I guess your plan is this: draw the attention of the police and society through the death of Li Manyu, and then expose yourself through the death of the second person, confront the police, provoke the police, put pressure on the police, and force the police to investigate you.

The DNA left behind.”

Sun Yu lit a cigarette, "So your counter-surveillance, photo taking, and pressure on the police should be planned after you kill the second person. If you plan until after the second person dies, you must have chosen

Okay, goal. So the question is, who is the second person?

It is not easy to be discovered, and I can still maintain a relationship with you. When I went to your community, I saw that there were very few surveillance cameras, and each building only had one on the first floor. I thought that this person should be by your side, and the probability of being a neighbor is very high.

Small, because your affair may be discovered.

I watched the surveillance and found something very interesting. Feng Yuanmei, the housekeeper in your building, is responsible for cleaning three buildings. She has been cleaning your building last for the past half month. It takes 3 hours to clean the other two buildings in total.

hours, but it will take 4 hours to clean your building.

I looked up this woman out of curiosity. She is 38 years old, pretty good-looking, and has average family conditions. She is usually a very thrifty woman, but she just bought a skirt costing more than 2,000 yuan a few days ago.

Tsk tsk tsk! Compared to her usual situation, my only conclusion is that she is in love!"

Qin Chuan's face showed a look of defeat. He leaned back and covered his face, "So you only have to do one thing after you are sure that it is her, and that is to follow her. It is too easy to follow an ordinary person.

.”

"Yes!" Sun Yu smiled, "And her life route is very simple. She works in the community during the day and goes home at night. It is much simpler than following you."

"Can I have a cigarette?" Qin Chuan suddenly returned to a depressed state, and his whole person was a little confused.

Sun Yu walked over and put a cigarette into Qin Chuan's mouth. He realized that the cigarette belonged to him, and Qin Chuan realized that it was the one he had left at Sun Yu's company in the morning.

Thinking of his provocation to Sun Yu in the morning, Qin Chuan laughed to himself.

Pure white cigarettes were lit, and the air was filled with the faint scent of tobacco.

"With your ability, you should have found that person, right?" Qin Chuan asked feebly, his voice a little hoarse.

"Um!"

Sun Yu's "hmm" not only shocked Qin Chuan, but also shocked everyone in the observation room. Everyone looked at Jiang Xiaoyu in unison.

Jiang Xiaoyu waved her hands quickly, "I just gave him the air ticket records from Mengshan to Tea Country over the years. Those are in tens of thousands. Those who can fly back and forth frequently are rich people. Who can check it?"

"

Therefore, when Sun Yu asked for this information the day before yesterday, Jiang Xiaoyu gave it to him without hesitation. She didn't even ask. After all, this was only auxiliary work, and catching Qin Chuan was the focus.

Earlier, Sun Yu locked the next victim through a flaw in Qin Chuan's question, which made everyone present feel suffocated, but they could barely adjust. After all, this was Sun Yu, a basic operation!

But now Sun Yu has even found that person. The police team works in groups, and Jiang Xiaoyu leads a group of people to do just this. Sun Yu solved the case and also found that person at the same time.

This is a bit embarrassing to the police force.

Zhang Shuo, who came to join in the fun, sighed: "We haven't seen each other for several years, but this kid is still so evil!"

Lei Zhen and others nodded in agreement, while Zhang Yao patted Zhang Shuo on the shoulder and comforted Zhang Shuo with the words he just comforted himself with, "Basic operations, basic operations!"

Qin Chuan looked up at Sun Yu, his eyes full of pleading, "Tell me everything you found about him, okay?"

Sun Yu bit his lip and shook his head, with a trace of pity in his eyes, "I can't tell you, you shouldn't listen to this. You have already confessed, and the chain of evidence can sentence you to death, so why bother with that anymore?"

After saying that, Sun Yu walked towards the door.

"Wait!" Qin Chuan shouted. Seeing that Sun Yu ignored him completely and put one hand on the door handle, Qin Chuan quickly said: "We can exchange. I have something the police want to know."

Sun Yu opened the door as if he didn't hear anything.

"I know where the arms dealer from Black Gold is!"
