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

"A normal girl wouldn't wear a skirt like this with these kind of socks and high heels."

"This kind of dress is obviously not in line with the aesthetics of this era."

"That means the murderer's aesthetic taste is still stuck in the 1980s."

"Check the stores that sell clothes in the city. Take photos and ask them where the clothes came from, whether they have surveillance cameras, whether they remember when they were sold, and whether they have any memory of the buyer."

"I'd also ask around at the DVD rental shops and get a list of regulars. I'd check their ages. They're men who like this kind of music, around 35-40 years old. They're mentally sound, have good personalities, are emotionally stable, and don't argue with others. Their families are decent, too. They live alone, perhaps because their wives have died."

"Find similar unsolved cases and compare them: rainy days, nail polish, newer clothes, and young women."

"Now, check everything I said."

Hou Zhen listened to Zeng Li's questions, read the case file again, and left without saying a word.

Zeng Li glanced at the center forward.

The center forward went out to supervise.

Zeng Li asked Cai Ming.

"Are there many police officers who have passed the exam after transitioning from military to government?"

"There are seventeen of them in our bureau."

Zeng Li read the remaining case files silently one by one. She did not expect anyone to be trained, but cooperated with Zhaocai and gave a very clear direction. After investigation, the case could basically be solved.

"Since there is no talent, we can start from other places, monitor the applications, approve more, and reduce the crime rate."

"If it's not approved, I'll donate it myself."

I originally wanted to teach Yi Xian, but I couldn’t do it at all.

Zeng Li left and the center forward stayed in the bureau.

She took the photo of the clothes to a small store to compare them. She bought the clothes wholesale in the south and sold them to a man for 140 yuan. She couldn't remember the exact time.

But there was surveillance footage during that period, so it wouldn't be difficult to check it a few days before Zhang Hongmei's death.

After finding the person, I compared it with the list of regular customers in the DVD rental store and found that it matched.

The center forward returned home and nodded to Zeng Li.

Zeng Li withdrew her gaze and stopped paying attention.

Go to the basement and do research with Gu Luojin.

In three days, Gu Luojin will leave.

Teach as much as you can before leaving.

“In fact, the essence of many things is mathematics.”

"In the end, the most accurate data that can be calculated within one's ability is used."

"From a dynamic design perspective, the design you've created is specifically for supersonic cruising, but it could be improved."

"For example, if the original speed is Mach 4-5, you can increase it to Mach 6 just by changing the wings."

“It requires precise calculation.”

"I can pick up math when I get back, find a teacher, and study it together."

"If you can design this to be a combined reconnaissance and strike weapon, it will be a nightmare for air defense systems."

Gu Luojin listened attentively, while Yi Xian and Lao Shu were watching from the side, with a very low sense of presence.

"Mouse, the leader is amazing. He can learn anything at a glance, and once the knowledge is in his head, he won't leave home."

"I need to read a lot of things many times before I can remember them. If I don't review them, I will forget the knowledge points after a long time. I need time to recall them."

Rats rarely comfort people.

"You are a normal person. Don't compare yourself to the leaders. You are one in a billion."

Hou Zhen is interrogating a prisoner at the police station.

Different prisoners.

So far, three out of eight have been correct.

Happy and sad.

I have been investigating for so long but have made no progress. Mayor Zeng just took a look and found everything broken.

Didn't sleep all night.

All I could think about was…was there any way I could learn from Zeng Shi and work alongside him? Like the man who supervised me today.

Once this thought comes up, I can't let it go.
