Under the night, police cars were wandering around Zhongyan Town with their sirens flashing.

The suspect Yang Ting carried a large amount of explosives. The nature of the incident was no longer just a kidnapping of a police officer. Public Security Director Zhao Changsheng demanded that Yang Ting be captured tonight. The armed police detachment also participated in the search for Ma Youran.

Sun Yu stood at the entrance of the alley where Yang Ting's house was with a cigarette in his mouth, sometimes looking at where Ma Youran got off the bus, and sometimes at the location of Ma Chaoqi's house.

This side is backed by a streetlight. Logically speaking, Ma Youran would choose this side after getting off the car, hiding in the darkness to prevent Ma Chaoqi from suddenly coming out.

There was half a bottle of wine and peanuts in Yang Ting's house. Judging from the scene, he was drinking. So why did he suddenly come out? The only explanation is that he knew Ma Chaoqi was back and he wanted to see Ma Chaoqi.

"Judging from Ma Chaoqi's call records, he did not answer the phone when he left the barbecue restaurant." Xia Lan came over, "Meng Yuan and Song Wa were about to arrive at the barbecue restaurant. The owner of the store said on the phone that there was surveillance.

I hope the monitoring can give some useful information!”

Sun Yu took a long puff of cigarette, and a scarlet light lit up in the darkness.

Ma Chaoqi's explanation was too far-fetched, but he was obese, had a big belly, and had indeed drank a lot. Sun Yu didn't think he had the ability to control Ma Youran and hide her within ten minutes.

, and finally went back home and pretended to sleep.

There must be an accomplice, and this accomplice should be Yang Ting. If Ma Chaoqi and Yang Ting are fully prepared, then the probability of them finding Ma Youran is very low, and the only entry point is Ma Chaoqi.

So now Sun Yu must prove that Ma Chaoqi is related to Ma Youran's disappearance.

Sun Yu slowly looked at Xia Lan aside. His team member was missing. The policewoman team leader's face was full of anxiety.

"Why did they want to capture Ma Youran?" Sun Yu asked.

Xia Lan hesitated for a moment, as if she didn't expect that Sun Yu would suddenly ask her a question. She said, "Because Ma Youran followed, Yang Ting found out that the police were eyeing Ma Chaoqi, so he arrested her?"

"It's very strange!" Sun Yu took a deep breath, "I always feel that the murderer this time is very strange."

Sun Yu also discovered the problem Ma Youran noticed. In the 206 laboratory explosion, the murderer did not consider the consequences at all. This may also be because the murderer did not understand the power of the pressure bomb.

But at the Mingbo explosion scene, it was enough to see that the murderer was very cautious and did not want to hurt innocent people. The two men's behavior was completely different.

Ma Youran said that Ma Chaoqi was not surprised by the explosion in Laboratory 206, but was surprised that Mingbo was killed.

Judging from the phenomenon, the explosion in Laboratory 206 is related to Ma Chaoqi, but Ma Chaoqi cannot understand the principle and replacement of the heating plate, and the murderer can only be Yang Ting.

If it is determined that the culprit of the explosion in Laboratory 206 was Yang Ting, then who was the one who killed Mingbo?

From a motive point of view, the killing of Zhao Peng was revenge, and the killing of Mingbo was to eliminate the obstacles to payment. It was too unreasonable to kill these two people at the same time. If Mingbo died and Zhao Peng was not there to pull the strings, how could they continue?

Looking for one?

Wait! Find another one?

What if we analyze it from the perspective of the beneficiaries? After Zhao Peng and Mingbo were killed, someone in the School of Chemical Engineering must have had a job change. This is one of them.

Secondly, this person may know about Zhao Peng's cooperation with Ma Chaoqi and Yang Ting. He found the two of them privately and promised that as long as they got rid of Zhao Peng and Mingbo, he would be responsible for the procurement of rare metals, thereby maintaining a relationship with the two.

Long-term cooperation, this is not just a profit of one or two million.

There is a third person, and he is from the School of Chemical Engineering!

Ma Youran's disappearance put great pressure on Sun Yu. At this moment, he finally figured out the motive of the explosion, but another question appeared again. What does this have to do with Ma Youran's disappearance? Is it really just because Ma Youran was following him?

Got them?

Sun Yu's and Xia Lan's cell phones rang at the same time, and Meng Yuan posted a video in the group. This was the surveillance footage of the barbecue restaurant that he shot with his cell phone.

During the surveillance, Ma Chaoqi filled up the wine and drank it all. In just thirteen minutes, he drank an entire bottle of liquor. Then Ma Youran left his seat and walked to the bathroom. Ma Chaoqi took out his mobile phone and looked through it.

Three minutes later, he suddenly got up and left, during which time he looked at the bathroom a total of five times.

"It's obviously intentional." Xia Lan's face became more solemn.

Ma Chaoqi drove here, and he drank so much alcohol, obviously just to take Ma Youran away.

Sun Yu's eyes turned cold and he turned around and walked towards Ma Chaoqi's house.

Xiang Fei has been by Ma Chaoqi's side since he brought his people here. The euphemistic name is to appease his emotions, but in fact, he is just monitoring him.

In the living room, Ma Chaoqi was still holding a cup of strong tea. The color of the tea was much lighter than when Sun Yu first saw him.

Xiang Fei sat on the sofa, folded his arms, and glared at Ma Chaoqi. Ma Youran disappeared while following Ma Chaoqi, and no one felt that Ma Chaoqi had anything to do with it.

Entering the living room, Xiang Fei stood up. Just as he was about to ask about the investigation, Sun Yu ignored Xiang Fei and came to Ma Chaoqi.

"Bring the mobile phone!" Sun Yu's tone was low and powerful, and his eyes revealed a sense of majesty.

Ma Chaoqi frowned, put down his tea cup, took out his cell phone from his pocket and handed it to Sun Yu.

"Unlock!" Sun Yu suddenly roared, making Ma Chaoqi tremble in fright, as if he had done too many things.

The phone was unlocked and delivered to Sun Yu.

After getting the phone, Sun Yu entered the phone settings page. First, he had to determine whether the phone could be used as a mobile phone clone. After confirming that it was not, Sun Yu opened the battery consumption ranking.

In addition to some commonly used software, Sun Yu discovered a mobile app called "Cool Wan'er". Coincidentally, this app has been uninstalled and cannot be searched in the app store. It can only be downloaded through the web page. This shows that this is very

Regular software.

Sun Yu searched and found that this was a companionship app that had not been certified. This type of app is very common on the market now. It is an online channel for men and women to trade, and is the favorite tool of electronic fraud gangs.

"Ha!" Sun Yu smiled coldly and glanced at Ma Chaoqi, "You're so old and you still use the app? Do you want to play with Lianliankan?"

At this moment, Sun Yu caught Ma Chaoqi picking the pad of his index finger with his thumb. This action also appeared in the surveillance video just now. Ma Chaoqi did this action before leaving the barbecue restaurant!

Sun Yu believed that this was a stress reaction that occurred when Ma Chaoqi was nervous.

"When did you uninstall this software?" Sun Yu asked, "I advise you to cooperate. We have technical means to see when you uninstalled the software."

Ma Chaoqi blinked, "In the afternoon, right? I clicked on an advertisement online before and never noticed that it automatically downloaded. Today I went in on a whim and took a look. The cover was very exciting, so I registered an account and took a look. The result
