Siheyuan: My name is Cao Xing, and I have a strong background

Cao Xing selected a dozen technical difficulties out of the thirty-three technical difficulties, and then used the space pawnshop to exchange for the relevant technologies.

For example, active control technology, comprehensive wing data, power technology, aerodynamics, and material technology, etc.

These are all very important things.

If researchers can master these technologies within a year, the country's fighter jets will be ahead of the world!

All these cost Cao Xing a total of 15 tons of gold, which was really damn expensive.

But Cao Xing knew that the research and development funds for these technologies would be extremely huge.

At the very least it will be ten times more than these fifteen tons of gold.

If you calculate it this way, the space pawn shop is still very cost-effective.

After all, these technologies are not dead things, but knowledge.

And it is currently the world's top undisclosed knowledge.

This will enable Chinese scientists to quickly complete their knowledge reserves.

Not to mention that these technologies can also be applied to other areas, which is enough to promote China's industrialization by a big step forward.

Cao Xing placed piles of technical information neatly on the table and began to study other issues.

The ten or so problems just now were only those that could be solved immediately; the rest could not be solved in a short period of time.

When pointing out the technical difficulties of insufficient machining precision of parts, Cao Xing also frowned.

He didn't know how precise the world's current industrial machines were, but he thought they had not yet reached the nanometer level.

The Hualong fighter jet currently has the most advanced technology in the world, and the error must be controlled at around one micron, which makes its processing extremely difficult.

Even a powerful country like Russia has just produced a prototype and has not yet been put into mass production. This is obviously because the processing accuracy is not enough to achieve large-scale production.

Even if Cao Xing exchanges it for the world's most advanced industrial machine tool, he will still encounter the same problem as the Russian bear.

Therefore, Cao Xing must find a way to improve the precision of industrial mother machines and break through to the nanometer level.

In this way, the world's top CNC lathes can be manufactured through industrial mother machines.

Only in this way can the Hualong fighter be fully localized and mass-produced.

It can be said that if Cao Xing solves these problems of the Hualong fighter, it will undoubtedly allow the country's industry to rise to two levels!

It is still unknown how much technological innovation in the industry will be driven by that time.

In short, for China, it is equivalent to a qualitative leap, which can be described as a small industrial revolution!

The Space Pawn Shop can only exchange items that are currently in the world. Even stocks can only be exchanged for three days, not to mention those advanced technologies.

However, Cao Xing was very open-minded. Since he could not break through the technological barriers, he would exchange them for a large number of the most advanced industrial mother machines in the world.

As the saying goes, diligence can make up for lack of talent, and the shortcomings of one person can be overcome by the strengths of two people. He can allow more researchers to disassemble industrial mother machines for research, and promote the development of industrial mother machines through large amounts of data.

Only Cao Xing can do this.

After all, the formation of an industrial machine can be said to be 30% technology and 70% luck.

No country can easily build the most advanced industrial machine tools.

Therefore, even if one is available, it is difficult to produce a second one in a short period of time.

Not to mention disassembling the mother machine. If you dare to do that, you will be shot for treason!

Therefore, this method is only applicable to Cao Xing.

As long as he has money, he can exchange countless units from the space pawnshop in an instant.

We have not yet reached the information age, but if Chinese scientists can conquer this industrial mother machine and create a more powerful one, it will undoubtedly lead to a series of reforms.

Among the remaining technical difficulties, two-thirds are related to industrial mother machines.

Cao Xing thought for a long time, and his decision became more and more firm.

With a sudden thought, he checked the world's most advanced industrial machine tools in the space pawnshop.

As expected, the most advanced technologies in the world right now are from Russia and the United States.

The above shows that the current accuracy of these two machines is still around one micron, and has not yet reached the nanometer level.

And the exchange price for these two machines is actually five tons of gold?

The calculation shows that it would cost around 800 million US dollars!

"This thing is too damn expensive!"

Even though all this gold was stolen, he still felt reluctant to give it up!

What does 800 million US dollars mean these days?

He remembered that the GDP of the entire United States this year was less than 700 billion!

They dare to charge 800 million for a single device. This is too much.

However, Cao Xing just complained a few words and the exchange had to be made.

Two hundred industrial machine tools were exchanged in one go!

Looking at the brand new and sophisticated machines in the space, Cao Xing couldn't help but feel a sense of luxury.

This is all money!

It took him thousands of tons of gold!

At this moment, he also had a little understanding of how his daily life was now.

Back in the real world, Cao Xing opened the door and walked out, going straight to Han Weiguo.

"Brother Han, where is Mr. Liu?"

Han Weiguo was waiting for Cao Xing at the door. Hearing this, he immediately replied, "Mr. Liu has gone somewhere else. Do you want to heat up your food now?"

"What food? I'm not in the mood to eat now."

More than a thousand tons of gold disappeared just like that. How could Cao Xing eat?

"So you're going to look for Mr. Liu?"

"Of course, why else would I come out?"

Han Weiguo said awkwardly: "Brother Cao, Mr. Liu left a message. If you have any instructions, just go ahead and fulfill them. If there is anything that must be discussed, I can tell you."

Cao Xing laughed helplessly and said, "Is Mr. Liu ashamed to see me?"

As a personal guard, Han Weiguo naturally knew what was going on. He came up to Cao Xing and whispered.

"Brother Cao, to be honest, Mr. Liu is really avoiding you."

Cao Xing shook his head unhappily. The money had been spent, what else could he do?

"Brother Han, go do two things right now."

Han Weiguo patted his chest and said, "Don't worry, Mr. Liu has given me full authority. I will do whatever you ask."

"Haha, then three things."

"Brother Cao, you are going to raise the price!"

"I'm not raising the price, adding this clause is the compensation I deserve."

"Okay, you say it."

Cao Xing raised a finger and said, "First, seal off this courtyard immediately and invite Mr. Liu and the researchers he trusts over."

"Second, Brother Han, find a large, empty warehouse and clean it up immediately. The area must be 10,000 square meters, and there must be at least a battalion of soldiers guarding it. If a fly gets in, it will be separated into male and female."

Han Weiguo assured after hearing this: "No problem, these are not a problem, what is the last thing?"

Cao Xing chuckled and said, "I want to meet Mr. Shi Chuan."

Han Weiguo was stunned. He didn't expect that this was the only request Cao Xing made for him.

"I have to ask for your permission. You know I can't make the decision on this matter."

Cao Xing nodded and did not make things difficult for Han Weiguo.

Cao Xing was very grateful to Mr. Shi Chuan as he had always protected him.
