After traveling through time, I, as a mechanical genius, am dedicated to improving myself.

Xiao Du said he was out on some business, asked everyone to be busy, and went to the criminal investigation department to look for Bo Zai.

"If you have any complicated, unsolved cases, send them all to Zeng Li. Now that she's here, it's a waste if you don't use her. You might have to pay for her next time."

Bo Zai felt that they were already busy enough and it would be inappropriate to add to the chaos by bringing on an old case.

"Director, Zeng Li is Nan Tian's sister. They both live nearby and can be invited over anytime."

Xiao Du patted Bo Zai.

"What do you know? He was poached by the National University of Defense Technology not long ago. I was a step too late when I called the Public Security University."

"When I came out, I saw that she was very confident in her judgment and hadn't looked into the case much. I guess she was waiting for Chen Yansong to come back. Take this opportunity to bring in some unsolved cases and test them."

Chen Yansong was indeed investigating according to what Zeng Li said. After all, the scope given was very small.

Bo Zai brought the case file and the marked map to Zeng Li.

Zeng Li pushed open the case file and opened the map.

The final calculation turned out to be Fu'an Building.

However, the environment of Fu'an Building is not suitable as a crime scene.

Bo Zai saw Fu An Building was circled.

"Sister Nantian, is this Fu'an Building?"

Zeng Li just looked up when Zeng Nantian walked in quickly.

"Zeng Li, there is indeed someone who completely matches your calculations, but there is no evidence."

Bo Zai was even more anxious than Zeng Li: "Where does that person live?"

"Near my home, Fu'an Building."

Zeng Nantian broke out in a cold sweat when he thought of his home.

Bo Zai snapped his fingers and said, "The place your sister just circled is Fu'an Building."

Ji Chen still felt unconvinced. He exchanged glances with Hu Jiarui and Jiang Jingjiang, then walked over to Zeng Li's position and glanced at the map on the table.

I did circle around Fu'an Building.

Zeng Nantian didn't care to be surprised: "Captain Chen is keeping an eye on him. We haven't alerted the enemy yet, but we don't have any evidence. We sneaked into his residence once and found nothing."

"My name is Xie Gui, I'm 25 years old, an intern in surgery. I'm a bit dull, and I think he's someone who can be bullied and manipulated by anyone."

"The day before the first victim died, his mother died."

"Now I'm an orphan with no parents. I only have a house in the suburbs. It takes me three hours to commute to get off work. I don't have a car, and my savings haven't been checked yet."

"When I work overtime, I live in the rented Fu'an Building, and most of the time I go back to my own home."

"That's all we know for now."

Zeng Li looked at the three representatives from the military, wanting to hear their opinions.

Hu Jiarui felt a little embarrassed when being stared at.

"We're not good at this, but we have good fighting skills. Once you're sure it's him, we can help catch him."

Actually... Ji Chen has experience, but no matter how experienced he is, he is embarrassed to say it in front of this little girl.

Zeng Li didn't care about anything else.

"Brother, let's assume... Chen Meiyun was a prostitute, Wu Hongying was a chronic child abuser, Xie Yating was into animal cruelty, He Siyu was corrupt, Song Juan was unfaithful, and Cao Tangmin was unfilial. Then their deaths would be consistent."

“The others are currently invisible.”

"Mainly investigate Chen Meiyun, then check the people working in the hospital to see if there are any gossipers. Are they neighbors of Wu Hongying? Or have any of Wu Hongying's neighbors visited the hospital where he works? Is He Siyu involved in the medical equipment business? There must be a connection. If we find the key points and follow the clues, we will find evidence."

"Once it's done, it will leave traces. There's no such thing as a perfect crime."

Zeng Nantian wanted to send Zeng Li back first.

Xiao Du, who had been silent for a long time in the back, said, "Nantian, go and do your thing first. I'll take Zeng Li back for you. I'll drive her back in a few minutes."
