This is the explanation. It seems that Yun Yi attaches great importance to the Mohist mechanism.

Yang Sheng thought for a while and suddenly asked: "The spies from Lingguo stole a large amount of information before, is there any Mohist mechanism?"

Yun Yi frowned slightly and shook his head and said, "No, the Mohist mechanism has not been found, and the Zero Country spies do not know its existence. However, the things that have been researched, a large amount of data being tested, and the teacher's personal notes have all been stolen.

"If all those things can be studied thoroughly, they may be enough to deal with ordinary level 5 early stage demigods."

Hearing that the Mohist art was not stolen, Yang Sheng breathed a sigh of relief: "That's fine, let alone Mr. Chen's notes and some research materials can be thoroughly studied. Even if it can, it should not be possible to complete all those things in a short time."

Haiyang nodded and said, "Yes, and even if all of them are thoroughly studied, they are just equivalent to ordinary level 5 early stage demigods. When they study it clearly, I may not be able to reach what level!

"Nuclear weapons can easily kill demigods above level 5, but the impact is too great and no country will use them for the time being."

Yun Yi said: "It's not as simple as you think. Whether it's nuclear fission or nuclear fusion, only the core part can kill high-level demigods.

"With current technology, the speed of missile launch is too slow for demigods. A single launch cannot kill a high-level demigod, and it cannot even be injured.

"It is unrealistic to use large-scale coverage and launch. The fission of the uranium nucleus will cause huge pollution to the environment.

"Although the fusion of hydrogen nuclei is much smaller, even so small that it can be ignored, its fusion process also needs to be stimulated by nuclear fission.

"The current technological level cannot achieve a simple nuclear fusion reaction, so as long as it is a nuclear weapon, it will produce radiation pollution. Unless the demigods have acted like a world-destroying behavior, they will do this with all their own gamble."

Huang Xinnan said at this time: "In other words, nuclear fusion is actually very powerful, but with current technology, it is still too difficult to control, and it can only barely stimulate nuclear fusion reaction?"

Yun Yi nodded: "Yes, humans can only use the ultra-high temperature generated by nuclear fission to achieve the purpose of fusion of hydrogen atoms, which is completely different from the nuclear fusion inside the sun.

"If you rely solely on heat to stimulate nuclear fusion, it will take hundreds of millions of degrees. Now, among you demigods, the strongest fire control ability is to reach nearly ten thousand degrees Celsius. That is the temperature that can instantly melt ordinary steel."

At this time, Huang Xinnan thought of the knowledge he had learned from his junior high school textbooks before and said in confusion: "I remember that although the temperature inside the sun is also very terrifying, it is only more than 10 million degrees Celsius, which is far less than hundreds of millions of degrees Celsius."

Yun Yi adjusted his breathing slightly and spoke faster, as if answering a question raised by a mentally retarded person: "That's because of the quantum penetration effect. Only the huge mass of the sun can make the extremely low-probability quantum penetration effect continue to occur.

"It is precisely because the nuclear fusion generated by the quantum transmissive effect is relatively slow and stable that the sun can burn stably for a long time."

Huang Xinnan also saw that Yun Yi was a little impatient, but continued to ask: "That was not possible before. Now, can we complete a pure nuclear fusion reaction with the help of magic power?"

Yun Yi shook his head and said, "No, it cannot be done with the current means within the scope of human cognition."

Yang Sheng nodded thoughtfully from the side and said, "Can we use other elements that do not produce radiation to carry out nuclear fission?"

Yun Yi had already frowned at this time. It seemed that Yang Sheng’s problem was even lower than Huang Xinnan’s: “First of all, nuclear radiation was not created by humans, but a phenomenon that has existed since the birth of the universe.

"It is the microscopic particle flow released from a nucleus from one structure or one energy state to another energy state, and this phenomenon is inevitable, but it has a big or small impact on humans.

"And, hydrogen atom fusion is the easiest of the known elements. Carbon atom fusion is as high as 200 million degrees, while iron element fusion can generate high temperatures of 6 billion to 10 billion degrees.

"Even inside stars that are much larger than the sun cannot meet such conditions, and such requirements can only be met when supernova erupts.

"Don't underestimate the universe. In the face of the laws of the universe, the so-called gods are not even ants!

"The mana weapons we are currently studying are far from reaching the power of nuclear fusion reactions, but they can be better controlled and flexibly applied in actual combat."

"Okay, I'm not like a teacher. I have the patience to explain too much scientific knowledge to you, because you won't study in depth at all. Just say anything quickly."

Yun Yi didn't want to continue talking anymore. He felt that for those who don't understand science at all, no matter how much they tell, they just listen to stories, which would not help scientific research.

Yang Sheng hurriedly said, "Anyway, this incident made me fully understand how fragile ordinary people are in front of demigods.

"Is there anything that ordinary people can use? I will exchange it for some and I will use it for my parents to defend themselves."

Yun Yi said: "Ordinary people can wear combat suits, which are relatively simple to make and have a lot of inventory. That thing is much stronger than a bulletproof vest, but it can only be worn in winter. In summer, because it is not breathable, ordinary people will be too hot to wear."

Yang Sheng expressed his understanding of this and said, "Forget it, I looked at the combat suit, it was just solid and could not play much protective role."

Yun Yi nodded. This Xuanwu 01 combat suit was originally developed and did not consider the needs of ordinary people, so it was not suitable for ordinary people to wear.

"There is also a kind of heart protection mirror. Now many important figures from many countries have worn it. When they are under strong impact, they can release energy shields independently. Unlike the simple energy conversion before, this time, it combines the defensive formation to withstand the full-strength attack of the early stage of the fourth level."

Yang Sheng's eyes lit up: "How many such heart protection mirrors can be replaced?"

"This kind of heart protection mirror is not much larger than the God-Destroying Pistol, and it is in high demand, so I can only give you three for the time being." Yun Yi said.

Yang Sheng thought for a while and said, "Six, I need six, and I can pay double the contribution points."

Yun Yi shook his head and said, "There are not that many, I can only give you five, three times the contribution points."

"Okay, are there other things that ordinary people can use?" Looking at Yun Yi's attitude, Yang Sheng knew that even if there were, he would definitely not exchange it for himself, so he asked if there were any other protective equipment.

Yun Yi looked a little unhappy: "No more, scientific research is not a joke. I have only been studying Mohist art for three months. How could I have so many research results?

"And even if we can have such a stock, it is because our country had a large amount of reserve technology before the appearance of the demigod, plus a large amount of manpower and material support."

Yun Yi's tone was not good, and he did not face the fear of three level five demigods and one level four demigods at all.
