Xu Yishan is 14 years old this year and is in the transition period between Lori and the girl.

Other girls probably just know what electricity is at this time. At the age of 14, Xu Yishan designed and built the first controllable nuclear fusion reactor. If it were still a peaceful era before the revival of Reiki, she would probably occupy the headlines of the global media for a long time, and be regarded as "someone else's child" by parents around the world.

This is related to Xu Yishan's experience.

She suffered from cancer as a child, and five years ago, her life hung by a thread and she almost died.

Sun Xiang saved her life by chance. It is said that if you don't die in a catastrophe, you will have a blessing, and Xu Yishan's blessing is her incredible IQ.

She spent her entire childhood in illness, and in addition to being obedient and sensible, she did not show any extraordinary talent. Her father, Xu Yongzhi, took her around to seek medical advice, and she barely went to school.

In order to make up for this shortcoming, Professor Xu Yongzhi often teaches his daughter various subjects on the road. But whether a professor teaches a class is actually different from an elementary school teacher's class. Professor Xu said a knowledge point and asked his daughter, do you understand? Xu Yishan nodded obediently, and Professor Xu continued to talk about the next one.

In this way, when Xu Yishan was eight years old, Professor Xu finally taught the "basic knowledge" in his mind. One day, he suddenly reacted: Hey, how did I finish all the content of my undergraduate physics at university?

However, Professor Xu was relieved in a blink of an eye, he thought, she is worthy of being his daughter, quite the style of a father. As he himself said, who is not a prodigy in this business. Xu Yishan's shocking IQ, in his eyes, is just "quite smart". Later, Xu Yishan's condition deteriorated, and this happy event was put down.

The turning point came after Sun Xiang cured Xu Yishan's cancer.

The little girl, who had been suffering from illness all the time, suddenly broke free from this shackle, and was stimulated by Sun Xiang's spiritual power, and her intelligence exploded in a shocking way.

One day shortly after she recovered, the aura had not yet been revived and the world was peaceful. That day, Professor Xu returned home and found that Xu Yishan had not written her school homework, but had written and drawn on a manuscript.

This manuscript is a relic of Xu Yongzhi's sister-in-law, Sun Yulan. After Sun Yulan died of illness, all the industries as an entrepreneur were left to Yu Xiaoyue. But her legacy as a great mathematician was left to her student Xu Yongzhi, including this manuscript.

Xu Yongzhi's research direction is not mathematics, and Sun Yulan's mathematical theory is too profound, so Xu Yongzhi just solemnly collected it and did not study it carefully.

Seeing that his daughter dared to scribble on such a precious relic of the teacher, Professor Xu picked up the slippers and was about to beat her violently. Xu Yishan hugged her head and ran away.

After the chickens flew and the dogs jumped, Professor Xu sternly questioned his daughter why she had scribbled on Grandma Sun's manuscript.

Xu Yishan replied aggrievedly, I see that Grandma Sun has a few formulas that have not been written, so I will help her make up for them.

Xu Yongzhi laughed when he heard this. Even if you are a primary school forest, you dare to talk about the research results of the teacher?!

I don't know how thick the sky is, let the father see how outrageous you are wrong! With such a mentality, Xu Yongzhi began to read the formula written by his daughter.

At two o'clock that night, Professor Xu Yongzhi walked out of the house in despair, found a roadside stall crookedly, and drank ten bottles of beer. He had never drunk before, but he was crying while drinking.

The roadside stall owner thought that his wife had run away with someone and gave him two dishes.

Only Professor Xu knew in his heart that he had been hit by his daughter's self-esteem.

He used to be a child prodigy, and he had always been very confident in his IQ, until this night, when he was completely crushed by his own daughter.

So in fact, the charm is very innocent, and she feels that she is very ashamed to be crushed by a little girl's IQ. But if she knew the pain of other scientists in the face of Xu Yishan, she might be relieved.

9 years old!

When Xu Yishan was 9 years old, she independently completed the algebraic algorithm of the eddy current formula. What she wrote on Sun Yulan's manuscript was the algorithm process.

The eddy current formula is very important and is widely used in cutting-edge technology. But there is no algorithm for this formula, in other words, humans cannot work out the answer by applying the formula. So there are many technologies that can't be realized, such as controlled nuclear fusion.

The eddy current formula has stuck humanity for three hundred years, and this fourth-order partial differential equation is beyond the limits of human intelligence. For three hundred years, countless mathematicians have tried tirelessly, but no one has solved it.

At that time, Sun Yulan also conducted some research on the algorithm of the eddy current formula, but finally stalled because it was too difficult.

Xu Yishan inherited Sun Yulan's work and gave the classical algebraic solution in an hour.

Mathematics is like this, it seems to be just a layer of window paper, but the person who can pierce this layer of window paper has a special name in the academic world:

Sons of the Plane!

For example, from the limit idea of ancient Greece to the establishment of calculus, this layer of window paper stuck mankind for nearly 2,000 years until the appearance of Leibniz, the son of the plane.

Xu Yishan is the son of another plane.

If Xu Yishan was not his daughter, Xu Yongzhi almost knelt down and called his father at that time.

Xu Yishan's incredible IQ should not have appeared, because the way of heaven is balanced. Heaven has given her the ultimate intellect, but also the incurable disease. Her life was supposed to end one day at the age of eight, and she was buried forever, along with her extraordinary intellect. However, since she survived, it must have become an accident in the Heavenly Dao.

She was supposed to make a career in the field of human science, but soon after, the aura revived, the demons invaded, the country disappeared, and the cultivators rose. Xu Yishan does not have the talent for awakening aura, but she also plays a huge role.

Professor Xu Yongzhi followed Yu Xiaoyue to develop a variety of new defensive weapons for Coastal City. It was an age of aura, and technology was considered to be obsolete because traditional weapons were useless against many types of demons. Many awakened practitioners instinctively hate technology, because everyone knows that science and metaphysics are fundamentally incompatible. Many of the forces that had fortified the city gave up their support for the scientific researchers, and instead focused on developing the power of the cultivators.

But the coastal city guarded by Yu Xiaoyue is a special case. Yu Xiaoyue is not fond of scientific research, but has been influenced by Sun Xiang. In getting along with Sun Xiang, Yu Xiaoyue can obviously feel his importance to science and technology. Even Sun Xiang himself has several doctorate titles in natural sciences.

Yu Xiaoyue believes that Sun Xiang, as an orthodox cultivator, not only does not reject science and technology, but also attaches great importance to it. Then metaphysics and science may not coexist as other practitioners say.

For this reason, Yu Xiaoyue retained the scientific research institutions of the coastal city, and in the early days of the troubled times, she accepted a large number of scientists from other cities. These scientists have lost their special status and have been reduced to precarious civilians, and when they learn that there is a city to receive them, most of them try to rush to them.

Binhai University became the scientific research center of the entire East, and Xu Yongzhi became the person in charge. The abundance of scientific power has brought many benefits to the waterfront. For example, the design and construction of the Luhe Giant Wall, such as all kinds of new weapons. Even the scientist organization is under the leadership of Xu Yongzhi to develop special weapons against spirit-like demons.

The fall of science is due to the ineffectiveness of disembodied demons such as resentful spirits. If Xu Yongzhi can succeed, then it will add a powerful weight to the human race against demons.

When her father was working overtime all day to build a big project, Xu Yishan was not idle, and her main credit was to solve the energy supply of the entire coastal city.

Before the revival of Reiki, Binhai's electricity supply mainly relied on coal-fired thermal power generation, and some light-water reactors were supplemented by nuclear power. Both of these types of power generation require the transportation of fuel from distant places.

As demons grew stronger, long-distance transportation became a fantasy, and the power supply to the coast was stretched. If the power is cut off, technological weapons will be useless, which is an important reason why many cities have given up on developing technology.

In order to support her father's career, Xu Yishan decided to solve the power supply of the entire city on her own. Any way of generating electricity, you need fuel, but there is a way to generate electricity, and its fuel is almost inexhaustible.

That is the use of heavy water for nuclear fusion.

Controlled nuclear fusion power generation technology, in the revival of Reiki is the top priority of human scientific research, but no country has been successful. Because nuclear fusion produces a large number of eddy currents in the plasma fluid, and humans cannot calculate the eddy current formula. So there is no control at all.

Do you still remember that Xu Yishan independently completed the algorithm of the eddy current formula when she was 9 years old. So she fully believes that she can achieve this miracle.

According to Xu Yishan's design, the city first built a heavy water plant, which extracts the abundant groundwater beneath the coastal strata and extracts the heavy water from it.

Then, on the site of the thermal power station, the first deuterium-ion fusion reactor in human history was built. This reactor fully meets the coastal preparedness requirements and living needs, and there is even a large surplus for Xu Yishan to carry out super energy-consuming energy tests. And the reactor doesn't have to worry about running out of fuel, and even if the groundwater runs out in a few decades, seawater can be introduced for heavy water extraction.

It's a perfect source of energy, and the only flaw is that almost all scientists refuse to work inside the reactor. Because the entire reactor was designed by Xu Yishan, the style is bold and bold, and the slightest carelessness will leave the bones. Except for herself, there is no confidence that she can live a day inside.
