This inexplicable feeling of uneasiness has not been removed for a day, and Yu Yifeng will not be relaxed for a day.

He has already figured it out, whether it is aliens or Martian monsters, as long as it is not a disaster like Resident Evil, he will solve it with nuclear weapons! As the most powerful weapon of mankind, the nuclear bomb is also the best protector.

If one shot is not enough, then two...... Two shots are not enough, then ten shots!

Whether the Noah runs away or bombs a flying saucer, it is inseparable from nuclear bombs. Of course, if even nuclear weapons can't be solved, humanity will be doomed......

12 billion-ton equivalent helium-3 nuclear bombs were manufactured, consuming a total of one-eighth of the human helium-3 reserves, Yu Yifeng was really a little distressed. After all, human helium-3 is really too little, use a little less. There are still a lot of scientific experiments that use helium-3, and it would be too wasteful to build nuclear bombs all of them.

Even so, this sense of security is not enough, so he desperately wants a more powerful and brutal nuclear bomb, which is - a four-hydrogen nuclear bomb!

"Professor Ding, how is the design of the four-hydrogen nuclear bomb?" This is the third time he has walked into the door of the Wild Wolf Design Bureau in recent times, and every time it is the same problem.

The main work of the Wild Wolf Design Bureau in the recent stage is to be responsible for the design of the super train. But now, the supertrain is also in good shape, and the test results are perfect, so the main researchers are also empty.

Yu Yifeng directly handed over the design task of the four-hydrogen nuclear bomb to them, and kept urging, we must do it quickly!

Professor Ding Yidong, the head of the department, was originally a weapon maniac and was very keen on these things. In addition, the little wolf cubs inside are all crazy and boundless madmen, and as soon as they heard that they were going to build a nuclear bomb, they immediately became interested.

"Quad nuclear bomb!"

"What kind of new term?"

"You've heard of the reaction inside the sun, where four protons fuse into helium nuclei under intense pressure and high temperature, releasing a lot of energy at the same time...... A nuclear bomb made using this principle became a four-hydrogen nuclear bomb. ”

One by one, they were very excited, took out paper and pens and calculated frantically, and at the same time shouted in the institute. This is the unique culture of the Wolf Design Bureau, and this kind of wolf howl often spreads to the outside, making the surrounding research institutes a little helpless.

The four-hydrogen nuclear bomb, a nuclear bomb developed with ordinary hydrogen elements, is the ultimate king of nuclear bombs, the kind that can almost be manufactured in batches and infinitely increase the yield.

Ordinary deuterium hydrogen bombs and helium-3 nuclear bombs are limited by raw materials and cannot be mass-produced. But the four-hydrogen nuclear bomb is different, it uses the most common hydrogen element, which accounts for more than 90% of all elements in the universe, and can be said to be inexhaustible!

However, Professor Ding Yidong has been engaged in weapons for so many years, and he really knows the ultra-high difficulty of the four-hydrogen nuclear bomb. According to the reaction conditions provided by the solar core, it is about 250 billion earth atmospheres and 15 million degrees of high temperature!

15 million degrees, this temperature is so-so, and it is not difficult for humans to reach it. But 250 billion atmospheres of the earth, this pressure ...... It's so perverted, it's equivalent to compressing gas to 150 times the density of water!

This pressure is equivalent to a force of 2.5*10^17 Newtons pressed on a place of 1 square meter...... To put it more vividly, that is, the gravity of 250 Mount Tai is concentrated in a square position!

This kind of pressure is impossible for humans to achieve. At most, humans can compress gas into liquid, and it is basically impossible to compress liquid into a solid substance.

The sun, on the other hand, has created such conditions for reaction because of its strong gravitational pull. But human technology simply cannot meet such conditions, so this is the biggest difficulty of the four-hydrogen nuclear bomb.

However, the young man under his hand was still excited, and he was still roaring majestically. Ding Yidong had a feeling in his heart: This group of young people is more crazy and self-conscious than him. He deliberately made a bad mistake and threw the research topic of the four-hydrogen nuclear bomb to them, wanting to kill their hearts.

As a result, after a while, his goal was really achieved, and they were all disgraced, as if they had lost their souls, and they could hit the wall when they walked, and the roar in their mouths was gone, replaced by muttering to themselves......

Anyway, all of them are settled a lot.

Ding Yidong was refreshed, and often laughed unconsciously, but Yu Yifeng was unhappy......

"If it really doesn't work, leave it to Tesla! They are also missing tasks now. ”

Yu Yifeng had a calm face, and he didn't scold, so he said like this.

When Ding Yidong heard this, his face changed, his face suddenly turned red, and his big voice immediately roared: "No, absolutely not!" In the field of nuclear bombs, they are definitely not as professional as us! ”

What he said is also true, they have too many arms here, and Tesla can't compare to it. But Ding Yidong is still faintly worried, in case this project is really let out, the people under his hands will have to rebel!

He can't afford to lose this man!

"It's been so long, why don't you even have a basic plan?" Yu Yifeng didn't want to push him too much, just urge the goal to be achieved.

"Why not!" Ding Yidong is most annoyed by others questioning him. But then again, there really isn't a good way to solve this problem, "It's not that we can't do it, it's just that a lot of front-end technology hasn't been completed yet!" ”

He immediately pulled out a few drawings from his computer, on which he drew a graph of temperature and pressure.

"This is a function of temperature and pressure of tetrahydrogen fusion, and we have not studied this reaction much in the past, and the function diagram is not complete enough, so we have to do a lot of experiments......

Saying that, Ding Yidong calmed down a little and sorted out his thoughts: "250 billion earth atmospheres, we humans can't do it, we can only increase the temperature to reduce the reaction conditions." ”

"At this stage, the maximum temperature that we humans can create is 10 trillion degrees! But that's the local temperature in the Large Hadron Collider...... There's no way we're going to ignite a nuclear bomb with a hadron collider, right?"

"Even if the helium-3 nuclear bomb is detonated and ignited. But it doesn't always work out ......"

"Laser ignition is also good, the most powerful laser, the instantaneous temperature can reach more than 100 million degrees, and the pressure is more than 100 billion atmospheres, I don't know if it will work......"

Thinking of the place where he was distracted, Ding Yidong began to mutter to himself, and even forgot that Yu Yifeng was on the side.

Yu Yifeng knew in his heart that this great scientist must have done his best. With Ding Yidong's character, it is impossible to be lazy, and he has been secretly studying for a long time I don't know how long. He definitely wanted to be completely done and take it out to make a splash......

But it turned out that the difficulty was really a bit high, and he still hasn't finished it. It's not that they don't give it well, it's really too hard! This ultimate nuclear bomb is still a bit too much for mankind to handle.

"There are a few options here, you can take them and see for yourself. Each one is theoretically feasible......" Ding Yidong finally came back to his senses and sent an email to Yu Yifeng's mobile phone.
