Siheyuan: I am Yi Zhonghai's biological son

He Daqing came back for two days and left again, but this time he was not in as much of a hurry as before. He felt relieved and at ease. In addition, he was going to have a grandson soon, which made him even happier.

Yi Ping'an still reads books every day. He never goes out unless it is absolutely necessary, just like a lady from a noble family. He never goes out of the house. Yi Zhonghai thought he was in seclusion again, but seeing him reading books every day, he ignored him.

The Spring Festival came in a blink of an eye. Due to the disaster, this Spring Festival was very lonely. The three members of the Yi family had a reunion dinner in the courtyard and paid New Year's greetings in the courtyard on the first day of the new year. Even though the new year was over, no one visited relatives now, and when they went to their relatives' homes, they had to bring their own food because no one had surplus food.

In the early morning of the third day of the Chinese New Year, Yu Li went into labor. Sha Zhu and the people in the hospital rushed Yu Li to the hospital. In the evening, she gave birth to a big fat boy. Yi Ping'an also went. Looking at Sha Zhu's face that couldn't stop smiling, Yi Ping'an was happy for him. He definitely couldn't call him He Xiao this time.

Sha Zhu was named He Yuanqing because he was born in the first month of the lunar calendar, which is a festive month. His nickname was Hutou because this year is the Year of the Tiger.

Not to mention that the name is nice, the nickname is also appropriate. The little guy can eat, sleep and cry. The cry can be heard throughout the whole compound. It is mainly because he is hungry. In order to give him milk, the new dad Sha Zhu went to Shichahai to break ice and catch fish in the middle of winter, but he got nothing.

There was no other way, so Yi Ping'an gave him two crucian carps weighing more than half a pound, plus two wild boar feet. This kid was too easy to cry, and sometimes he would wake him up in the middle of the night.

On the sixth day of the New Year, Yi Ping'an went to school early in the morning. Today he was going to attend a seminar with his teacher Wang Guodong.

When I arrived at the school, I found that all the participants were heavyweights, all of them were big names. The dean was also there, and the others were at the same level as Wang Guodong. It seemed that the standard of this seminar was not low.

The group went to Huaqing University, where they met many big names in different professions of this era in the auditorium. After following the teacher around, Yi Ping'an felt like he was sweating on his forehead. Each of them was like a senior teacher.

Yi Pingan felt that this trip was worthwhile, but what surprised him even more was the leaders who came later, who were also the initiators of this seminar. Yi Pingan was really surprised. Yi Pingan looked at Wang Guodong and couldn't help asking in his heart: Teacher, are you sure this is a seminar? Not a report meeting? Why are there so many leaders?

The biggest leader was an old acquaintance. Yi Ping'an knew that he was mainly responsible for scientific and technological projects, such as growing mushrooms.

Yi Ping'an had to take it seriously to be able to meet these leaders in such an occasion. Sure enough, many of the questions raised were about the big mushroom. Others might not know it, but Yi Ping'an knew it, because the secret recipe of the big mushroom had long been made public in later generations. Who doesn't know what the raw materials of this thing are?

It seems that this is a brainstorming. There are chemical engineering, physics, aerospace, and mechanics. Yi Pingan is not interested in the other issues, but the mechanical issues really shocked Yi Pingan.

"How to determine the centrifugal force through the rotation speed and centrifugal radius?" When Yi Ping'an saw this question, the first thing that came to his mind was "centrifuge". To be precise, what the leaders wanted was a uranium enrichment centrifuge.

Anyone who has studied mechanics and physics knows the principle of a centrifuge, just like a washing machine in later generations. The principle is very simple, but it is the most difficult step in growing mushrooms. Otherwise, why are there so many countries that cannot grow mushrooms even though the formula for later generations has been made public? It is because they cannot separate uranium 235 and uranium 238.

As for separating these two, centrifugal separation is the most advanced method. In fact, there are other methods to separate uranium, such as gas diffusion method. China used this method in its past. It was not until 2013 that it truly mastered the centrifugal separation method and built a uranium enrichment centrifuge.

It can be seen how complex the technology of this thing is and how difficult it is to make a breakthrough. It not only involves the fields of mechanics, power, and electricity, but also related knowledge of computer applications and materials.

Do you think that just one centrifuge is enough? No, you need many. How many? For example, Iran in 06 announced that they used 235 centrifuges to enrich uranium 164, and they had more than 3000 in stock. Because this thing is disposable and cannot be repaired, isn't it infuriating?

Why do we need so much? Because the first separation is not pure, so the uranium 235 is separated in a centrifuge and enters the second centrifuge through a pipe for further separation, and so on, one after another, until the purity of the mushroom you want is reached.

This is too complicated, but Yi Ping'an wanted to give it a try when he saw it. Even if he can't do it, aren't there so many experts out there?

He knew about the theories of later generations, although it was only a vague introduction because it had to be kept confidential, but he had seen a washing machine, so at least he knew the specific data, such as the rotational speed and the Mach number. These big names were linked together, and he didn't have to fight alone, so there was nothing to be afraid of.

Yi Ping'an thought it over and began to recall the data about centrifuges from his previous life, and then wrote and drew on a notebook. Anyway, he was just there to make up the numbers in this seminar, and no one would notice him if he did something else.

His actions were soon noticed by his teacher, and Wang Guodong was puzzled. Why did this child suddenly become so excited? He was writing, drawing, and thinking. What was he doing? So he moved closer to Yi Ping'an to see what he was writing.

Wang Guodong looked at what Yi Ping'an wrote, and he became more and more serious and his breathing became faster and faster, so that everyone around Wang Guodong felt something was wrong and thought to themselves:

"What's wrong with Lao Wang? Is he sick? Why is he having trouble breathing?"

"We have to keep an eye on Lao Wang. He's obviously in poor health. If anything bad happens, we need to send him to the doctor immediately."

As a senior engineer, Wang Guodong naturally knew how advanced his student's machine was, but he couldn't think of anything else, especially things related to mushrooms. But it didn't stop him from knowing that this was a technical barrier, and his students were breaking the technical barriers. How could he not be happy? This was something that could be included in textbooks.

Yi Ping'an was completely immersed in his own thoughts. Even after the meeting was over and everyone had left, he was still sitting there writing and drawing. People around him sensed something was wrong. Was he getting inspiration?

They all wanted to see what this kid was writing and why he was so engrossed in it. However, no one at the scene made a sound. They were all engaged in scientific research and everyone knew how important inspiration was. Even though they were all gathered around him, there was still silence.

Yi Ping'an had long been surrounded by people from the Industrial College, who were staring at the people around them. They were all people in the circle, almost all of them knew each other, either classmates or alumni, and they were all exchanging glances.

"What is that young man from your school doing?"

"What's your business?"

"Who is that young man?"

"From our school."

It was not until the leader of the xx Institute who initiated the meeting today saw this scene that the eye contact ended.

But the leader also understood, so he continued the silent communication and pointed inside: "Can I go in and take a look?"

The person he asked immediately turned to look at their dean, who nodded. The leader quietly stood behind Yi Ping'an, stretched his neck and began to read what Yi Ping'an wrote.

When he saw the simple drawing, his eyes widened. When he read the concepts, principles, data and other contents, the leader covered his mouth directly. He was afraid that he would scream out loud, so he took two deep breaths and calmed himself down. Then he walked out of the encirclement and gestured to the people outside to let them disperse.

Then he made a gesture to their dean and asked them to disperse. There were people guarding this place, but Wang Guodong stayed. We can't just leave him here even though he is someone we know. Looking at that young face, we can tell that he is not very old, so let's let his parents stay here.

Wang Guodong also felt something was wrong at this time. What on earth did this guy do? Even if it was a technical barrier, it shouldn't be such a big deal, right?
