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

"Mr. Zeng Li, have you decided on the National University of Defense Technology? Are you not going to change? Don't you want to be your brother's colleague? You can even be his supervisor."

Zeng Li pretended to be asleep and didn't make a sound.

Of course Xiao Du could see it.

That's a respectable way to reject someone.

As soon as the car stopped, Zeng Li unbuckled her seatbelt and said, "Thank you, Director Xiao. Be careful when you go back."

Before Xiao Du could say anything, Zeng Li had already left.

After watching Zeng Li enter the house, he returned to the bureau to continue his work.

Zeng Li doesn't care about these cases. When considering the popularity of surveillance, she thinks it can really reduce a lot of crimes, restrain the evil of human nature, and make it easier for her to hack into the system later.

Shuyi sat on the sofa and waited.

"Finally you're back. I couldn't sleep peacefully without you. Don't stay so late next time."

"Good mother."

After he finished speaking, he heard Zeng Sanhu's snoring coming from the room.

"Mom, go to bed. I'm going to take a bath."

Not long after Shuyi entered the room, the snoring stopped.

Zeng Li washed and went to bed quietly.

There were days when I didn’t go to the garbage station.

I don’t know if I could scrape together two stun batons for self-defense if I go there again.

The crime rate is too high these days.

Have to guard against it.

Before the case was solved, Zeng Li still did not leave the house except for morning exercise.

Three days later, Zeng Nantian returned home on time for dinner and gave Zeng Li a wink. Zeng Li knew that the case was over.

"The three people sent by the military wanted to see you. I told them you were going to study at the National University of Defense Technology soon, and they said they had disappeared and had packed up and taken everyone back last night."

Zeng Li stretched and said, "I can go out normally tomorrow."

"When did you become so outstanding? How come I didn't know your brother?"

Zeng Li awkwardly withdrew her outstretched hand and feigned stupidity, saying, "Is this considered excellent? I can be even better."

"How come you suddenly know so much about criminal investigation?"

"I don't understand, I'm just putting myself in their shoes."

Zeng Nantian couldn't understand: "From the perspective of a perverted murderer, why did he kill people?"

Zeng Li shrugged her shoulders, her tone full of helplessness.

"But brother, if you want to catch a criminal, don't you have to think about the situation from the criminal's perspective? Most criminals are inherently abnormal, otherwise they wouldn't commit such extreme crimes. Serial killers, in particular, are incapable of normal thinking. If you can't think in the same way, it's hard to catch them."

"Everyone's words, behaviors, small movements, and micro-expressions reveal a lot of information. We also need to learn from their upbringing and family education methods."

"These are essential for solving the case."

That makes sense. Zeng Nantian just doesn't understand why his sister, who grew up with him and was only good at math but not very good in other areas, suddenly...

Looking at Zeng Li's profile, he chose to continue asking questions.

"Zeng Li, tell me, how come you suddenly have so much knowledge in your head?"

"I have a lot of stuff in my head, but I don't show it unless I need it. Go read the book in the corner of my room and improve yourself."

The brother and sister were fighting and playing.

Zeng Li woke up from her exercise and came back. She didn't even have breakfast. She grabbed a bag and couldn't wait to go to the recycling station.

After being busy at the garbage station for a few days, I found a stun gun and immediately gave one to Shuyi and taught her how to use it.

Who would have known that she would try it first with Zeng Sanhu.

"Lili, open the door quickly, your dad has fainted."

"This thing you gave me, I clicked it, and he shook a few times and then passed out."

"very scary."

Zeng Li put down her tools and quickly opened the door.

"Mom, are you using my dad as an experiment?"

Shuyi nodded: "What should we do now? Should we send him to the hospital?"

Zeng Nantian heard the noise and came out, just in time to hear Zeng Li say.

"No need to send him. He will wake up by himself tomorrow. But, Mom, this is not a punishment. In the future, please don't shock Daddy when he makes a mistake. Too much shock is not good."

Zeng Nantian pondered the stun gun for a while and felt a little tempted.
