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

Forget it, don’t worry about seniority, you can’t get past Zeng Li anyway. The point now is that it’s a rare meeting, so I quickly asked myself the question that I’ve been curious about for a long time.

Jiang Min'an's attention was focused on Zeng Li alone.

"I've been wanting to ask you a question for a long time. I've disassembled your surveillance system before, but found nothing. I'm really curious about...how this works. Could you please give me some pointers?"

The desire for knowledge is all in the eyes.

After I dismantled the surveillance camera and looked at it, I felt that the surveillance cameras sold by Zeng Li were all a mess of things put together, with no logic at all, but they were really useful.

Repeated denials and research have not yielded any answers.

Zeng Li had reached this point and would no longer play dumb. She would think about what she should say so that the other party could understand a little.

Complete understanding is impossible.

Because the concept of wireless digital waves did not come about until two hundred years later.

I saw three faces looking at me curiously.

Zeng Li blinked to ease the dryness before speaking, "Actually, the only useful part of the entire surveillance system is that piece of glass. There are numbers on each piece of glass, which are invisible to the naked eye."

"We can connect to any satellite, preferably a good one. So we initially used satellites from Country M and Country R, ​​plucking them back and forth. Country R didn't publicly launch any satellites, but it's actually controlled by Country M. The satellites were manufactured in Country M, and they're generally good enough to be used."

"The key is the receiver. As long as I make it, I can make it react to the numbers on the glass again. It can be understood as a set of codes. If the numbers are the same, the connection will be successful and it will work. There are more principles involved, but you won't understand even if I listen to you now."

Zeng Li didn't say that engraving numbers inside would require either tinkering at the beginning of production or having robots do it later. Anyway, the glass in the factory is just ordinary glass, there are no secrets at all, so you can check it out at will.

Jiang Min'an thought carefully about what Zeng Li said, drawing inferences from one instance. "Could it be understood that... as long as the numbers are correct, it doesn't matter whether it's glass or not. Glass was just an option you chose at the time because it's easier to hide the numbers. Putting aside glass, it could be anything, like numbers carved into wood, on the casing of a machine, or somewhere else? As long as the numbers are correct, it will have the same effect."

After Jiang Min'an asked this question, Chi Guoxiang, who didn't understand at first, now understood.

Without waiting for Zeng Li's answer, he quickly asked, "Zeng Li, can we sell them overseas? The cost is so low, we'll make a fortune."

Jiang Tianchen smiled but said nothing. It had already been sold abroad.

I pulled a lot of strings myself and it took a lot of effort.

Zeng Li avoided the topic.

"What's wrong with Li Ke? How dare you ask me to buy a robot?"

Jiang Tianchen finished the tea in his hand and rubbed the tea table with his cup. Zeng Li subconsciously glanced at Jiang Min'an.

It is impossible not to trust him, so the most likely reason is that he is afraid that the other person may be plotted against and it is not convenient for him to tell him.

Just like designing Niu Qing, sometimes it is really hard to guard against.

Chi Guoxiang hadn't reacted yet and was still wondering why he was using a teacup to grind the tea table?

Isn't this a signal that there are outsiders present and confidential information should not be discussed?

I looked around and there was no outsider.

Jiang Tianchen warned: "Who knows what he is thinking, remember to pay taxes on this 40,000 yuan."

Zeng Li looked at Jiang Tianchen in disbelief. How poor... were they?

"I have a genuine antique from Liang Zihui. If I sell it abroad, it could fetch hundreds of millions. In China...it might only fetch around 10 billion. Do you want one?"

Jiang Min'an had never come across this before, but when he heard about the huge price difference between domestic and overseas, he finally understood why so many Chinese treasures ended up abroad. They were all sold!!!

"Aren't you going to keep it for the game? Wait until you're done using it."

Jiang Tianchen seemed to know Zeng Li's plan.

The two of them tacitly agreed not to continue this topic.

Seeing this atmosphere, Jiang Min'an took the initiative to suggest going for a walk in the outer courtyard.
