After a long conversation, Sima Ji did not leave Liu Hui's house until the sun was about to set. Before leaving, he bowed, "I will benefit a lot from having a long talk with the old man. The King of Japan will come again to ask for advice."

"Why is Your Highness so polite to an old man?" Zhang Da said when he returned, "Your Highness's face looked ugly. Should you invite Liu Hui to the mansion to be a guest, so that your Highness will not have to come here in person."

"The other party is an old man, so it's time for me to come over and ask for advice." Sima Ji sighed and asked, "Do I look ugly? Maybe I was so excited and tired for a moment, but I can still withstand it when I am not old."

His face looked ugly because he saw a treasure, but it was almost hollowed out. There were too few mathematicians like Liu Wei in China, and it would be a pity to miss it. In his eyes, Jia Xu, Guo Jia, and Chen Qun of the Three Kingdoms were not as good as Liu Hui. There were those who had counselors in all dynasties and generations, but Liu Hui only had one.

After calming down, Sima Ji thought about what to do! Liu Hui is nearly 70 years old. To put it bluntly, he may go to see the King of Hell at any time. Of course, Sima Ji wanted Liu Hui to make use of his remaining energy in the last few years and teach his own knowledge as much as possible, even if it is a cramming education, to some of the Boy Scouts in Yanshan Camp.

But can the other party still travel far now? Sima Ji felt a little headache when he thought of Liu Hui's age. It's a pity to let it go. There is only one, only one, and I don't know which dynasty it will be if it appears next time.

Sometimes Sima Ji had to think about a question, why did such a group of mathematicians appear in ancient Greece, not one, but one group, and this group of mathematicians are different from mathematicians in other regions. Whether it is Persia, India or China, they all focus on high practical arithmetics. Why does the other party value geometry without practicality?

In addition to the era of the Spring and Autumn Period and the Warring States Period, the second wave of ancient China left some real works on the dynasties that were truly metaphysics, including the Wei, Jin, Southern and Northern Dynasties. Moreover, the more it seemed that there were less and less related to science, the fact that gunpowder could explode, and knew that it was 100, 2002 sulfonium and 3003 charcoal was not discussed in depth, so it stopped at black gunpowder and failed to develop yellow explosives. The invention of gunpowder, so there was the explosives used later in industry and military. This statement is wrong, and yellow explosives have nothing to do with black gunpowder.

It seems that the more centralized the power, the further away from science, I will not say anything about it in the Qing Dynasty. However, the behavior of my Ming Dynasty who translated half of the geometry originally proved that I was not behind the world, let alone the second brother. Geometry was originally a product of Shang Yang's reforms.

If it was just China who was beaten later, it means that it was only China's own problem, but this is not right. India and Arabia are also civilizations as famous as China, and their performance is not as good as China, which means that China's centralization is certainly unable to overcome the industrial revolution, but facing Western powers, it is still more than better than other civilizations.

Therefore, centralization should not be a problem. It has its own benefits? It is closed to the country? This makes no sense. The Ming and Qing dynasties were intermittent and did not become a national policy until it was implemented until death.

If things are pushed to the point of being closed, Iran, India, Ottoman, and Ottoman have never been closed, and are bordered by Europe, you can feel the changes of the other party at close range. If Sima Ji put himself into the role of Ottoman, he could only experience the helplessness of watching the other party surpass him little by little.

Those empires that were not closed to the country seem to be worse than those of me, the Qing Dynasty.

"According to Marx's understanding of feudal system, China's similar era was the Zhou Dynasty, and the Jin Dynasty's feudal division also had this meaning. Do we have to split the country to make the mind active?" Sima Ji, who couldn't sleep at night, tossed and turned, but the cost was too high. If it was Western Europe, wouldn't it be India?

"No, productivity determines production relations. New China is also centralized. Isn't it fierce to catch up? Centralization is the most suitable model for China to find." Sima Ji sat up directly, still confused in his mind. China and Europe are just two systems. Compared with each other, it seems that many suitable people are not suitable for China at all.

Fortunately, China is a rare country in the world where monarchy is suppressed by the church. Although it was easy to turn around, Japan and South Korea were temporarily leading when they started, but later these two countries did not take them into consideration at all.

"If I have the day of the reign of the court, I must go to Greece." Sima Ji made a decision that he had to go to Greece to learn the other party's knowledge. However, before that, use the people in his hands first. He must let Liu Hui and himself go to Youzhou and teach his knowledge to the Boy Scouts by example.

In fact, there was another history of changing dynasties like China, which was ancient Egypt. Judging from the time of the establishment of the pyramids, the history after ancient Egypt has been changing dynasties and finally became the most popular. From the 3,000 BC to the end of the history of the ancient Egyptian dynasty, it was almost three thousand years old, which was one thousand years longer than the change of dynasties in China.

It was almost the same period when the history of the change of dynasties in ancient Egypt ended. China took over the baton of ancient Egypt and began to carry out its own change of dynasties until the Qing emperor abdicated. This should also be considered that the ancient Egyptians encountered a large filter and were filtered out. China was obviously dozens of orders of magnitude larger than Egypt in area and population, and the large filter did not filter out China.

The next day, Sima Ji went to Liu Hui's house again. He went there quite early and waited for Liu Hui to get up before entering. The King of Yan felt that he was no less than Liu Bei who visited the cottage three times, but it was worth it. People like Liu Wei were rarer in China than Zhuge Liang.

This time Sima Ji was already prepared. He came here to talk about logic this time. Liu Wei had a study of geometry and would definitely understand what he said. On the contrary, those metaphysical powers in the court would definitely not understand.

The King of Yan actually didn't understand logic, but it didn't matter. He took out everything he knew. Although he had already returned to the embrace of nature from Arabic numerals to four-character operations, he had learned it at least. Some of the words Liu Wei said could just remind Sima Ji of some knowledge that he had long forgotten.

This may be the happiest day since Sima Ji was in the Jin Dynasty, because the other party could understand what he said. If he had a few more Liu Hui, he would not have to start talking to himself and deducing it, just like inheriting the mental illness of the Sima family.

"To be honest, I want to invite the old man to Youzhou and pass on his own knowledge." Sima Ji felt that the time was almost over, so he spoke to him. This was his purpose. The entire Jin Dynasty was just a single seedling, and if he missed it, he would be gone.

Hearing Sima Ji's words, Liu Hui sighed in a daze and said, "King, I am old and I am close to my seventies. What else can I do? I really feel like I met too late and I am fascinated by other countries that the king said. But I can't do anything anymore, and I can't deduce anything at this age. What's the use of asking me?"

"The old man's words are bad. In Ji's eyes, Mr.'s talent is far greater than those so-called famous scholars who are famous all over the world. Whether it is Wang Rong, Shi Chong, or Shan Jian, I am not in my eyes. Even my teacher Zhang Hua is slightly inferior to Mr. Zhang." Sima Ji calmly commented on some famous scholars of Jin Chao, and then changed his head and said, "If the old man can go to Youzhou with me and carry forward the words and deeds that he has learned, I am willing to treat him with a teacher's courtesy."

Wang Rong and Shi Chong were both famous scholars all over the world. Shan Jian was the second most famous among the Seven Sages of the Bamboo Forest, and now he was the governor of Qingzhou. As for Zhang Hua, he was in charge of the government, and in Sima Ji's eyes, these were not as useful as Liu Hui.

Even Liu Hui, who was old, couldn't believe that he could get such an evaluation from a prince, but he still said, "Your talent is not inferior to me, why do you still have to find me?"

"I, well, I still have a lot of things, I really can't be distracted." Sima Ji's old face turned red but immediately covered it up. How could he have any real talent?

Yes, King Yan knew the pi, and it was even more accurate than Liu Hui knew, but what was the use of this? He knew it was because he had memorized it, and Liu Hui knew it was because of Liu Hui's round cutting technique. The other party could start to calculate now. Sima Ji would not have no idea if he did not use the round cutting technique invented by the other party.

When talking about the round-cutting technique just now, Liu Hui was very self-reliant, because he was the first to create such a method, which can accurately reach the four decimal places, and is an extremely huge calculation process. This is definitely not something that anyone can do. The reason why he didn't say the last two digits when he was 3.14.

"Old sir, I sincerely hope that Mr. and I will return to Youzhou. Mr. may think that he has written enough to spread the books to future generations, but I want to say that there is no good master who teaches by words and deeds. It is not enough to just explore from books. The inheritance of knowledge requires a guide. I have many masters of metaphysics in the Great Jin Dynasty, but there are only one great talent like Mr. It would be a pity if Mr. brings what he has learned throughout his life into the loess." Sima Ji said sincerely, "I will choose the smartest child as your student. When the old sir has a hundred years, what he has learned will definitely be carried forward."

Sima Ji's invitations one after another were enough to show his importance. At this time, Zhang Da brought Liu Hui's son in and said, "Your Highness, Mr. Liu is willing to help persuade the old man."
