"Yes! I don't know if you need to buy special glass or bearings this time? Or do you want them all?" Wang Bin nodded after hearing this.

Then Donald ordered special glass and bearings of about 5,000 energy coins from Wang Bin, and then he took out the technology he brought this time.

Donald took out a stack of drawings, handed them to Wang Bin, and said to Wang Bin: "This is the technology I want to use to deduct the purchase of these products this time!"

Wang Bin took the drawing from Donald and looked at it for a while, and found that the technology in the drawing was somewhat beyond his expectations.

Originally, he thought that Donald's first deduction would not be too advanced, and it was also impossible that their world-class technology would be the one.

However, in fact, the technology given to him by Donald is not simple. Even if it cannot be compared with Wang Bin's world-class technology, it may be a little different, but it has very high value. Even most countries in the world cannot make things in the drawings at all.

All Wang Bin is sure that the technology in the drawings is definitely the top technology in the world where Donald is located, or strategic technology.

The technology Donald has developed is an aircraft engine technology and a turbojet aircraft engine technology.

The most important thing is that if we follow the data on this drawing, the proportional impact created by this engine has reached about 11, which is what surprised Wang Bin the most.

Even in the world where Wang Bin is located, there are not many countries that can produce jet turbojet engines.

But it is not very rare, at least a dozen, but there are very few countries that can produce high-performance engines.

Especially in countries that can produce engines of more than ten, there are very few, even the fourth-generation engine of the Bald Eagle.

Although the single thrust of the F-two-two engine reaches about 18 or even 19 tons, its engine is actually only about 10 tons.

However, in the world where Donald is located, their country is already able to produce aircraft engines with a 11th qualifying round. How could he not surprise him!

If we look at the normal development of Wang Bin's world, in the late World War II, although their country had developed and produced jet engine engines.

However, the technology is still at a very primitive stage, and it is impossible to achieve this level.

When Donald saw Wang Bin's expression, he knew what Wang Bin was thinking. He said: "Mr. Wang! In fact, this drawing was not entirely designed by our country.

I believe Mr. Wang, you also know that the technological level of my world is that even if I have gathered most of the outstanding aero engine experts in my country, the jet engine designed by the jet engines still have many shortcomings, and the maximum is only 7-8.

So after our world's experts designed this engine, I looked for a professional engine design store in the mall and made major design modifications to complete the design of this engine.

However, even so, with the technological level of our world, the performance of the engines manufactured can only reach about 80% of the design data, which is about 9% of the bump ratio.

This is why we have used the bearings and other accessories provided by Mr. Wang. If we do not use these materials and accessories provided by Mr. Wang, it will be very difficult even if we want to reach 9."

Wang Bin nodded, and asked the system secretly, "System, please ask the technical drawings Donald brought this time, how good is its performance, how good technical integrity, and how many energy coins can it be deducted?"

Although Wang Bin has a certain understanding of aircraft engines, he is actually only limited to ordinary people, and even compared with those military enthusiasts, it is not as good as that of military enthusiasts. Therefore, of course, it is impossible to know the technical performance of this engine. The best way is to ask the system.

"Host! According to the data of this drawing, the maximum length of the engine in the drawing is 4.9 meters, the maximum diameter is 1.1 meters, the maximum diameter of the nozzle is 0.61 meters, the self-weight is 1.0 tons, and the maximum thrust is 120 kN.

The technical performance is very good for the world where the host is located, and has reached the international advanced level of the world where the host is located.

At the same time, the engine technical integrity in this drawing is 100% except for engine material technology. According to the system identification, the deduction price of this engine drawing shall not be less than 10,000 energy coins. The system recommends that the acquisition be carried out at the lowest energy coins of 10,000." Just as Wang Bin finished asking, the system gave the price of the acquisition of this engine.

Wang Bin was still a little surprised at the price given by the system. In the system, the price of the engine with similar performance to this engine is as high as about 100,000 yuan.

However, the technology that purchased this engine from Donald was only priced at 10,000 energy coins, which made him feel that it was really expensive to buy technology from the system.

But then he understood why the technology sold by the system was so expensive.

This is because the technology sold to him by the system will directly instill the technology into his mind, and there is no situation where he cannot understand it thoroughly.

It even includes some other related technologies, such as how to build production lines.

So in fact, the technology itself is not expensive, even lower than what he acquired from Donald.

However, the price of the knowledge instilled in the mind of the system is not comparable to these technologies themselves, so the price purchased from the system is higher.

Wang Bin, who came back to his senses, said to Donald: "Mr. Donald! Your engine technology may be the top aeroengine technology in your world.

Compared to my world, your engine technology is still not comparable to those truly high-performance engines.

However, as our Tiangong Technology, it will be enough for the first-class aircraft engine in my real world in the future, so I have accepted this technology. As for the deduction price, it will be calculated based on the price identified by the system and 10,000 energy coins!" Wang Bin said.

Donald nodded and said, "You can, Mr. Wang! Just calculate it at this price."

Donald was not surprised by the price given by Wang Bin. In fact, when he brought the engine technical drawings and data to the mall, he had already asked the system to appraise it, so he had known this price for a long time.

Then Wang Bin and Donald chatted for a while, and they returned to their own worlds separately.
