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

Zeng Li took three case files.

When the time came, I didn't count the number of people or say hello to the school leaders. I just showed off.

In fact, Jiang Tianchen gave that person time to clean up his mess and arranged for himself to go to the People's Public Security University. How can this not be considered giving himself a chance?

These people in front of me, old and young, are all connections from different periods, or... followers.

"See you again, classmates."

"I have graduated and I am back to teach you for a month before I take up my new position.

Speaking of graduation, Zeng Li looked at the center forward.

"High center forward, isn't there a 100,000 yuan reward for graduating within a year? Remember to ask for it for me."

"Okay, leader."

The students burst into laughter.

Zeng Li looked at the children and ignored the leader in front.

Pointing to his shoulder straps, he said, "Not only did I graduate, I also became the youngest general in my country."

"You guys have to work hard too."

"Otherwise, if we meet outside in the future, you are not allowed to call me teacher."

Zeng Li first demonstrated her abilities, status, and power, making herself the idol and goal of these children. With this filter, everything became easier to do and easier to talk about.

Who says star-chasing culture can't be used here?

"Next, let me talk about the first case in class. It's a bit special and rare to come across."

"Since there's no blackboard, I won't write it. I'll just tell everyone orally, or see who can bring the blackboard over tomorrow."

"The 27 men died in different ways, but without exception, they were all tortured to death by various means."

"Hearing this, does any student have any first thoughts?"

Cheng Yunqing was quite courageous and willing to show off: "Teacher, the murderer might be a woman who hates men."

Zeng Li felt that it was very inconvenient and that teaching in this way was not very meaningful.

"Jiang Kai, go find a large piece of cloth or board."

I'm looking forward to Zeng Li asking another question first.

"Have any classmates ever killed chickens or ducks alone?"

Many female classmates held it.

Zeng Li began to call out the names of the students who raised their hands.

"Su Xian."

Su Xian was stunned for a moment, then he was delighted that the teacher actually knew his name.

"Teacher, we always kill chickens at home during festivals."

"Do you remember the first time you killed a chicken?"

"I was so flustered I don't remember much."

Zeng Li motioned for her to sit down.

"Actually, this can't be considered physical work, but it's certainly more suitable for men. However, when I looked at everyone raising their hands just now, only three men raised their hands."

"Don't boys do housework at home?"

"Li Ru'an, how many times have you killed chickens?"

Li Ru'an stood up and said, "Teacher, I've killed many, many times and have become very skilled."

"Have you learned any tricks?"

"There are some that you have to be decisive and quick. The water has to be hot enough and you have to pluck the hair quickly, otherwise the water will slowly cool down and it will be difficult to handle."

Zeng Li motioned for her to sit down.

"Killing someone is almost the same."

"The first time I kill someone, I feel nervous, flustered, and maybe even scared. I also feel some physical discomfort."

"Gradually, they got used to it, became proficient, and mastered certain methods. Unless the murderer wanted to provoke the police, most of the time they would kill in any convenient way."

“Because the simpler it is, the fewer traces it leaves.”

“It’s harder to find them.”

But there are some exceptions.

"For example, the murderer killed people just to torture them."

"He'll do whatever he wants, whether it's to vent his anger on the victim or for sexual stimulation, but it's mainly manifested in... slowly torturing people to death."

Jiang Kai came back.

The center forward lent a hand and the two of them got a board.

Zeng Li picked out some less bloody photos and projected tutorials, which could show the details and make the explanation more vivid and easier to understand.
