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

After coaxing Shuyi, he quickly handed the person over to Zeng Sanhu.

Pull out your phone and send a text message.

"Teacher Xu, I have to go back to school tomorrow. Do you want to meet me there? Then we can have lunch together. If you agree, we can meet at the school gate at 10 o'clock."

Xu Jing agreed.

Jiang Yanli came over here and Zeng Li also greeted him.

"Colonel Jiang, see you at the school gate tomorrow at ten o'clock. It's the weekend, and the students and teachers are not here, so it'll be quiet. My story begins at my alma mater."

After a busy day, put down your phone and have a good sleep.

ten o'clock.

school entrance.

Zeng Li slipped over using her walking shoes.

"Good morning, Teacher Xu, Colonel Jiang."

"Teacher Xu, this is Colonel Jiang. He wants to know the history of my talent development. I think I'm not very clear about it myself."

"I go to school every day, so... could it be because of the school's prime location?"

"Colonel Jiang, take a good look at my alma mater. Even my homeroom teacher knows everything about my school life."

"You guys chat slowly, I'm going to go get new business for the company."

He stamped his left foot and left quickly.

Jiang Yanli stared at Zeng Li's shoes with great interest.

Zeng Li didn't care after she left. She gave the two a chance to get to know each other, but she didn't get involved in how the relationship developed.

Stroll to the police station.

"Director Xiao, I have better surveillance. Would your police department consider it? It's very cheap. With surveillance, the crime rate will be much lower. It's a great deal."

When Xiao Du heard it was surveillance, he didn't even raise his head.

"How much cheaper can it be?"

"300 yuan each."

Xiao Du pressed too hard with the pen, causing scratches.

"How many did you say?"

Zeng Li knew the current price, and three hundred was the price she came up with after careful consideration.

"300 yuan."

Xiao Du stood up and said, "You wouldn't be so bored as to come to the police station and make fun of the police chief, would you?"

"That won't happen."

"Your company is new. My wife said you don't even have an office, and the information you provided is inflated. Where did you get the surveillance footage for me? Can you have a production line without an office?"

When he got close, he whispered, "Do you know how much a surveillance camera costs on the market? How can you make money with 300 yuan?"

Xiao Du was so excited that Zeng Li even drooled and took a step back.

"I'm not just doing this for the money. If I were to make money, I have too many things to do. I really want to make a little money while making the country and the city better."

"With surveillance, if something happens, wouldn't it be easier to deal with it? At least there's a clue. If people know there are surveillance cameras on the streets, won't they be more restrained?"

“Do you think twice before doing something bad?”

"Reducing crime? Isn't that good?"

Very good, absolutely amazing, especially at such a low price. It couldn't be better. Xiao Du still had the same question: "Where did you get the surveillance camera?"

“I won’t tell you, but it must be legal and compliant, otherwise why would I come to the police station to discuss business?”

Xiao Du thought about Zeng Li's series of actions and felt that they made some sense.

"I'll count the numbers and see how much budget the bureau has left. I have a good relationship with the provincial government, so I'll use the reasons you mentioned to convince them. I believe it won't be difficult to take over the entire province's surveillance."

"That's even better."

After Zeng Li finished the deal, she stayed at home for a week, sitting in front of the computer every day.

The only problem that surveillance can’t solve is cameras.

The camera collects light through the lens, converts the light into electrical signals to generate digital images, and then outputs them after processing. However, this is no longer necessary in the 25th century. There is a new type of glass lens that can replace the camera.

It requires a satellite network connection.

Zeng Li is trying to steal satellite network.

In this way, even if someone wants to pirate their own surveillance and study the principles, they will not be able to figure it out, and there is no need to apply for a patent.

Because the receivers and reflectors need to be built by ourselves, and the system is connected to the satellite, it cannot be pirated.

And the cost is... a few dozen dollars?

It is certain that you can make more than 200 yuan from one surveillance camera.
