Ning Xiao's home is a two-bedroom apartment in an old family building on the east side of the county.

This is once the village agricultural machinery factory staff dormitory, the agricultural machinery factory belongs to the collective enterprise, there have been very glorious days, at least in the eighties, the products of the agricultural machinery factory have radiated the surrounding two cities and seven counties, but after two thousand years with other collective ownership enterprises to decline.

The factory has long since been sold, and only three five-story buildings built in the early nineties remain.

Lao Ning entered the factory at the age of eighteen, and took over his father's class at that time, and the brother of the chairman of the trade union in the factory helped him get this 63-square-meter welfare house, which has become the last wealth of the Ning family.

Ning's mother followed her sister to work in the Shencheng Special Zone when Ning Xiao was six years old, and after being dazzled by the outside world, she divorced Lao Ning when she came back, and then returned to Shencheng and became a member of the Special Zone who dedicated her youth to the Special Zone.

At first, he would call Ning Xiao twice a year, but since Ning Xiao went to junior high school, there has been no news.

So Ning Xiao, who was sensible, was actually brought up by Ning's father. The two men are still very introverted, so you can imagine how boring life is on weekdays.

This is probably the reason why Ning Xiao will be obsessed with doing questions.

After all, apart from reading, life really didn't give him much to look forward to.

It's like today, after Lao Ning brought Ning Xiao home, Ning Xiao went into his room with the kitten, and Lao Ning took out his mobile phone and kept making calls outside.

Although Ning Xiao has already reached adulthood, as Ning Xiao's father, he will have to take care of these things after all.

……

Ning Xiao closed the door, he didn't care who Ning Dad was talking to outside, but carefully put the kitten on the table, took out a laptop from the cabinet, and turned it on directly.

This notebook was commended to him by the county education bureau after he received the admission letter from Huaqing University last year.

The champions in a small county town on the 18th tier of China naturally cannot be compared with the champions cultivated by those key high schools in the city. But for Ning Xiao, it was already an unexpected joy to have this laptop, even if the configuration of the computer was not high-end. At least now it comes in handy.

What he had to do now was sort out what he had learned in his dreams, or the paper that Lord March had instilled in his mind.

Yes, the learning process just now was weird, as if someone was transferring knowledge into his brain. Even in his dreams, he felt a dull pain in his head.

So he didn't really have a complete grasp of this paper.

In the words of Lord March, this is just to give him some benefits in advance, and it will take at least a month to integrate all the concepts and formulas in the paper.

For example, in the paper, a very common concept in mathematics, the Fourier transform is used superbly, which at least makes Ning Xiao, who has learned some integral transformations in Huaqing University, feel breathtaking.

In the words of Lord March, this is just the least worthwhile paper of its former owner, but when Ning Xiao read the title of the paper, he found that it may be a topic that he will not be able to climb in his life.

《Proof of existence and smoothness of solutions of Navier Stokes equations》。 (Proof of the existence and smoothness of the solution of the Navier-Stokes equation)

If Ning Xiao is not mistaken, this is a world-class problem. When he was in Huaqing, he listened to a classmate who had participated in the physics Olympiad talk about this problem at night.

Ning Xiao still remembers that he listened to the two classmates lying on the bed talking about fluid mechanics, fluid balance equations, turbulence and so on, and finally when it came to the N-S equation, he only dared to lie there and pretend to be asleep.

It's not that I don't want to participate, it's that I don't know how to interject at all.

Looking back now, I suddenly feel that they were talking very shallowly at that time.

If there must be an analogy, that is, the students are discussing the universal applicability, but this paper uses gravity to discuss various small-scale divergence in detail, discusses the divergence kinetic energy of fluid divergence in arbitrary small turbulence, and explores the control of these divergent kinetic energy on the solution of equations at extreme scales......

In this way, while typing and drawing pictures on the computer, Ning Xiao restored the papers in his mind, while systematically combing the knowledge in his mind.

There are also lemmas and theorems that I can't figure out for the time being.

But this does not prevent him from reverting to those complicated formulas and argumentation processes. By the way, you can also deepen your memory and understanding. He was so attentive that Dad Ning opened the door several times, but he didn't seem to realize it.

It wasn't until night was falling that Ning's father finally knocked heavily on Ning Xiao's door.

"Xiaoxiao, come out, your uncle is here."

Ning Xiao woke up in shock, looked at the kitten that was still lying on the table, and looked at the content of the paper that had been processed for less than a tenth of a few hours, and then stood up and walked out of the room.

……

Three men sat in the small living room, with a plate of pig's head meat, a plate of dried braised incense and a bottle of Lao Baigan, and three wine glasses on the coffee table.

The uncle picked up the cup and drank a glass of wine directly, and then said solemnly: "I went to the police station in the afternoon and chatted with Lao Li, and he said that Xiao Xiao's matter is big or small. He suggested that you take Xiao Xiao to record a confession tomorrow, and when you are discharged from the hospital, he is calling you all over for mediation. ”

Lao Li said that the pickled goods were not clean, and the people in the house did not believe what they said. When mediating, it will help us scare the other side, 500,000 is definitely impossible, but the medical expenses have to be paid to others, and we have to pay tens of thousands more. ”

Ning Xiao's eldest Beren, Ning Jian, took over Ning Wei's grandfather's class a few years ago and became a small cadre in the agricultural machinery factory. In a small county, it can be regarded as a wide range of friends, and it has some face.

Ning Xiao was silent, but Ning Xiao's father was red-eyed, raised his head, and said indignantly: "I heard Xiao Xiao say that it was they who found the trouble first. So many people bully our little ones, punching and kicking, why do you want us to lose money? At most, I only pay for medical expenses, and I want to blackmail our Lao Ning family, so I fight with them! ”

Uncle glared at Ning's father, and said angrily: "Fight, fight, it doesn't matter how old you are, what should you do?" He is a top student, and he will go to the capital to study in the future, and he will get ahead! What is tens of thousands of yuan compared to Xiaoxiao's future? Now this society is about the law! ”

Then, the uncle glared at Ning Xiao again, and said, "And you, Xiaoxiao, you don't go to school at all, just review at home and prepare for the college entrance examination!" This time when you arrive in the capital, you must be careful, don't be driven back! I know you are in difficulty now, there are 100,000 yuan in this card, you pay them first, and then return it to me when the little boy makes money later! So decided! ”

After speaking, the uncle took out a card of the rural credit union from his pocket and slapped it heavily on the coffee table.

"Brother, this is what you prepared for Ning Xiao, right?"

"Don't worry about it! In the future, when the little one is out of the way, will he not take care of his only cousin? Besides, the money has to be repaid. ”

However, Ning Xiao raised his head, looked at the uncle, and asked seriously and stubbornly, "Uncle, do you believe me?" ”

"Huh?"

"I can go to college without taking the college entrance examination!"

"Huh?"
