The master-shaped fighter is not really stealth, and its stealth does not make us feel ashamed. The real purpose is to make the radar unable to detect the existence of the aircraft. As long as the radar cannot scan the existence of the fighter, then the stealth fighter can achieve unimaginable results on the battlefield.

However, stealth fighter jets are not perfect. First, the cost of stealth fighter jets is very high. The maintenance cost is also very amazing. Some countries with slightly weaker strength cannot afford stealth fighter jets at all.

Secondly, in order to achieve stealth effects, stealth fighter jets have to sacrifice power and even some performance.

This is almost common sense in the scientific research community. However, no country can make a breakthrough in these common sense for the time being.

The same is true for the United States, the overlord of the stealth fighter world.

However, in front of Du Cheng, who has knowledge of future science and technology, there is no difficulty or problem in all this.

Under Du Cheng's instructions, one of the scientific research members came over with a cart, and there were more than 20 telescopes inside.

When these telescopes were allocated to the eyes of the Prime Minister and Ye Nanling, Du Cheng said: "This Stalker stealth fighter uses a wide-band wave absorbing material developed by our scientific research base, and is made of carbon energy-consuming plastic materials added to the substrate of multi-layer foam after chemical deterioration of polyurethane. It maintains effectiveness within a quite wide frequency range. Combining radar wave absorbing material with net-based substances that can be transmitted through the radar energy, its reflection energy is almost zero, which is about ten times more than the reflection energy of a mosquito."

Du Cheng briefly introduced this technology. After a pause, he continued: "This material has very specificity in the structure of the fuselage and the flow shaping shape. The Stalker stealth fighter we studied is currently the top level in the world in terms of power performance and attack.

After there is no regulation of flow shaping, the design of the fighter will have no restrictions on the shape, and there is no need to sacrifice power and performance.

Originally they thought the effect of this Stalker fighter was already extremely amazing, but they did not expect that the Stalker fighter displayed by Du Cheng was almost terrifying.

Moreover, they heard another more important news from Du Cheng's tone. No wonder they looked familiar when they looked at the stealth fighter just now, because the stealth fighter seemed to be a new Boeing fighter that Du Cheng had slightly improved.

Ye Nanling glanced at Du Cheng and asked directly: "Du Cheng, do you mean that the new wave absorbing material you have developed can be used on any aircraft?"

At this time, he finally understood why Du Cheng kept it secret yesterday, because only after it was kept confidential would the research results be even more amazing.

Du Cheng nodded gently and said, "It's almost the same. As long as the body is not as big as a large passenger plane, basically most aircraft can only use this layer of material to achieve the purpose of invisibility."

While explaining his words to Ye Nanling, he also explained one thing, that is, what was the most successful research this time was this new type of wave absorbing material. As for the fighter jet, Du Cheng said it was nice, but in fact he just transferred a high-level fighter jet from the military and applied it with that layer of wave absorbing material.

However, the research on wave absorbing materials consumed the great efforts and efforts of Du Cheng and a group of scientific researchers.

As for the listener Du Cheng's answer, the Prime Minister and Ye Nanling were already looking at each other. Obviously, they both saw what this technology really represents, which was far more amazing than they imagined.

Immediately, the Prime Minister seemed to have thought of something and asked directly at Du Cheng: "Du Cheng, why is this? What is the cost and degree of manufacturing wave absorbing materials?"

The absorbent material developed by Du Cheng is easy to use. However, the cost required for this is too amazing and the production capacity is low, its usefulness will be greatly limited.

It can be said that this is the thing that the Prime Minister is most concerned about at the moment.

Du Cheng had considered this a long time ago. He listened to what the Prime Minister said, and said very simply: "Prime Minister, why is the manufacturing cost of wave absorbing materials very low. If it is just an ordinary stealth fighter, the cost required will not exceed 1.6 million. If large-scale research and production are carried out, I think it should be possible to produce roughly three wave absorbing materials used for stealth fighter jets every day."

It seems that the production capacity of three aircraft a day is a little lower, but if it only takes a certain amount of time to accumulate, it can form the world's most terrifying stealth fighter team.

Moreover, the cost of this kind of absorbent material is not too amazing. Even if it is coated with a thousand racks, it will only be more than one billion at most. Even if it is several times more, it can be fully affordable with the financial resources that China has shown internationally.

After listening to Du Cheng's words, the Prime Minister was obviously relieved, but the excited expression on his face became stronger.

Not only him, but even Ye Nanling and Ye Chengtu and others saw a scene of the future at this moment, as if countless stalkers in the sky were waving to them.

Du Cheng did not disturb them, but gave a wink at Team Leader Guan, then slowly said: "Prime Minister, this is the first technology we have developed. Come with me, and I will take you to see the second technology displayed this time."

"There is a second technology?"

Just with the first technology, the Prime Minister and the others were already very excited. He never expected that Du Cheng would prepare the second technology.

Therefore, when he heard Du Cheng talk about the second technology, both the Prime Minister and Ye Nanling were already full of expectations on their faces.

After the impact of the first technology, each of them was full of expectations for the second technology that Du Cheng would develop next.

Du Cheng nodded softly and said, "Prime Minister, please come with me, I will take you to another exhibition hall."

After saying that, Du Cheng did not stop, but directly led the Prime Minister and Ye Nanling and the others toward the gate where he and the scientific researchers had walked out.

The researchers followed Du Cheng and the others one by one. The old hearts on their faces could be seen with a little excitement as if they were looking forward to the display of the art of "The Destiny".

Compared to the hall in front, the second hall is obviously smaller than Xu concubine.

The hall is also very empty, with only a workbench placed in the middle of the hall. Several large pieces of metal are placed on the workbench.

Apart from that, nothing else was seen outside the entire hall.

What made the Prime Minister and the others feel a little confused. They are thrown into pieces of large metals, which look like they are either iron or steel, and some alloys, but they don’t seem to have any outstanding features.

"Ye Hu, come here."

Du Cheng did not explain anything immediately, but waved to Ye Hu. After Ye Hu approached, Du Cheng took out an electromagnetic laser knife that had been prepared long ago from the workbench. After handing it to Ye Hu, he said, "Ye Hu. Try to stab these metals a few times. Just stab it."

Although Ye Hu didn't understand what the new technology Du Cheng showed was, he had no doubt about what Du Cheng said. Without thinking, he turned on the switch of the electromagnetic laser knife. After waiting for the electromagnetic laser knife to flash out, he directly held the knife tightly and stabbed towards the large pieces of metal.

Later, the Prime Minister and his friends' eyes were already gathered on the metal stones, as if they could see the metals as flowers.

Ye Hu's movements were very fast. In just a few seconds, he easily stabbed more than a dozen times. With the terrifying edge of the electromagnetic laser knife, he stabbed a small hole directly with almost every knife.

If it were *the human body, there would probably be more than a dozen holes.

After stabbing, Ye Hu turned off the switch of the electromagnetic laser knife, and just as he was planning to hand the knife back to Du Cheng, a strange scene happened in front of him.

I saw that the metals seemed to have become liquid in the hole that was pierced, and then the metals began to move quickly, and the small hole was changing rapidly. In less than ten seconds, all the pierced small holes healed, as if they had not been pierced at all.

"this"

Just looking at this strange scene, Ye Hu was completely stunned, his mouth was wide open, and he almost shouted "Damn it."

Out of instinct, Ye Hu turned on the switch of the electromagnetic laser knife again, and then pierced more than a dozen small holes into the metal.

But everything was still the same. In just less than ten seconds, all the holes healed on their own.

Behind him, the Prime Minister and his friends also looked similar.

Compared with the first technology, the impact this second technology seems to have brought them greater.

In their eyes, these metals are no longer cold metal bodies, but are living bodies that possess life.

Ye Hu finally reacted. He even forgot to turn off the switch of the laser knife in his hand. Instead, he asked Du Cheng: "Du Cheng. What's going on? How can these metals heal on their own?"

"Forgot to tell you the names of these metals."

Du Cheng smiled slightly and explained: "These metals appear to be no different from ordinary metals on the surface, but they all have a very unique name, that is, a life metal."

"Life Metal   Ye Hu murmured lightly, he was sure that the name was used on these metals, and it seemed that it was appropriate.

Only the metal that possesses life can heal itself when it is injured, but all this seems to be too weird.

"Du Cheng, how did you do it?"

Ye Hu asked very directly. Not only did he not think of this matter, but the Prime Minister and the others could not think of it either.

Although there has been a metal self-repair technology in the world, it is a fine powder combination material composed of various mineral components such as light-based magnesium silicate, additives and catalysts. That is, metal wear self-repair material.

However, the principle of this metal wear self-repair material is completely different. It is used by adding it to various types of lubricating oils or greases. Lubricating oils or greases are used as carriers to feed the fine powder particles of the repair material to the working surface of the friction object to achieve the effect of repairing metals.

Moreover, this kind of repair can only be done with small curves of wear and tear repair. Compared with this kind of repair at this moment, it is definitely a difference between fireflies and scorching sun.

Du Cheng did not answer immediately, but asked a scientific researcher to take out a laptop and put it in front of everyone, waiting for the computer to play the relevant picture and project it directly to enlarge it. Then he said: "We have conducted some research on metal wear self-repair materials and extracted one of the very unique chemical catalytic components. After this chemical catalytic component is combined with force-chemical action, it can be stimulated by the heat energy generated when metal friction is rubbed. These metals are refined by fusing this chemical catalytic component."

After pausing, Du Cheng pointed directly at the picture in the computer and continued: "Ye Hu, it's like you stabbed in with an electromagnetic laser knife just now. The heat energy generated by the electromagnetic laser knife quickly stimulates the chemical catalytic components in these metals. The chemical catalytic components contained in these metals are stimulated under the force-chemical action of thermal energy, thereby achieving the ability to cultivate oneself."

Du Cheng said it very simple and somewhat profound. However, after cooperating with the pictures flipped on the computer, everything became very clear.

Not only that, in the video that Du Cheng had already recorded, he also gave a detailed explanation of the chemical catalytic components, and gave a direct explanation of the principle after the two were stimulated.

Under such circumstances, even Ye Hu, who had no idea about this aspect, had a rough understanding of this second technology.

The third update is here to continue tomorrow.
