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

Zeng Sanhu's original words: "My excellent genes need to be passed on."

Who would refute this? To refute this would mean that he has bad genes, which is the same as saying that Zeng Nantian and Zeng Li are bad.

Maybe because no one refuted him, he became complacent and thought his idea was right.

After dinner, Zeng Nantian and Zeng Li took Chen Yansong for a walk downstairs.

Shuyi knew that they wanted to talk about something, so she pulled Zeng Sanhu away and didn't disturb them.

"It's no use looking for me. There are too few effective clues."

Chen Yansong knew that he had said everything he could say last time, and the victim's network of relationships was still being investigated.

"I came here mainly to tell you."

"Perhaps you're right about the 1968 case. The neighbor who gave the confession, Li Wen, was arrested in another city in 1989 for rape and murder."

Zeng Li shook her head: "It doesn't matter. It happened too long ago. It doesn't mean much."

"That's not the case. Some families have been waiting for justice and don't think it's too late just because it's been taking too long."

Zeng Li glanced at the somewhat excited Chen Yansong and said, "Maybe, but this is only a minority of people. I still think it's more important to live in the present."

Chen Yansong wanted to say, your mother was murdered, even if justice comes late, you still hope that justice will come, rather than waiting for any news until you die.

Looking at Zeng Nantian, Zeng Li was right not to understand. She was too capable and would do whatever she wanted herself. Besides, Zeng Nantian was the type who would take revenge on his own.

Neither of them could possibly understand this sentiment.

Chen Yansong is different. He can understand it because he is also one of them.

This was the first time Zeng Nantian gave Zeng Li serious advice after they broke up.

"Are you really not considering becoming a police officer?"

Zeng Li kept her distance and moved her hands occasionally.

"I've been solving cases all the time, but I've never been promoted? If I were promoted, wouldn't I be unable to play a role if I just sat in the office like Director Xiao?"

"Brother, study hard. I have my own ideals and ambitions."

Zeng Nantian shut up.

Zeng Li just said yesterday that there were too few useful clues, and today five more bodies were found, all of them women.

Electrocuted, bitten to death by dogs, strangled to death, scared to death, and stuffed to death.

This time I can see the appearance clearly.

While the body was still there, Chen Yansong quickly called Zeng Li over.

Zeng Li came to the conclusion.

"These people are more like experimental subjects. The murderer is testing something by using different methods of death. Because no matter whether they are men or women, they did not have sexual intercourse, which is relatively rare in this case."

“There is basically no gap in the time of death.”

"The key...how do we get these people to cooperate?"

"After all... there are too many ways to die."

Zeng Li was also troubled.

Thinking of Guo Mao in it, I remembered what Teacher Xu said, that her age gave her no advantage in the blind date market, and the only advantage she had was that she had some money. So if Guo Mao was willing to marry Teacher Xu, was it just for money?

"Captain Chen, check these deceased people to see if they were all short of money."

In normal cases, excluding manslaughter, the motives are nothing more than beauty, money, and power. It is impossible for so many people to kill for revenge or passion, so these can be ruled out.

Well...if it wasn't money, it would be really hard to imagine what made these deceased people willing to cooperate.

Zeng Li put all the autopsy reports together.

Why are the methods of death different, but the locations where the bodies were dumped are the same?

How did the murderer target these people?

Is the way of death random or fixed?

There were too many deaths, which attracted the attention of the higher authorities.

Zeng Li also stayed at the police station during the day, and was the first to show any clues she found.

Finally, when the body was dumped for the third time, Zeng Li took a picture of the van and was glad that the surveillance camera was replaced in time.

The original surveillance camera had very poor pixels, but this new camera can zoom in to see the driver's appearance.

Xiao Du realized the benefits of surveillance and thought about how to get more funding to install more surveillance.

"Zeng Li, when you go to the provincial government to install the system in a few days, remember to show off your skills and let them know how powerful you are."

"Let's talk about it after we catch him."

Zeng Li is not so optimistic.
