Although Yu Yu was as skinny as a stick, he was hale and hearty. E Guan Bo was sitting on his knees behind the desk, looking at Chen Caozhi. Ran Sheng entered the thatched cottage one after another. Chen Caozhi was handsome, tall, delicate and elegant, while Ran Sheng was as tall as an iron tower.
It was extremely majestic, and the thatched cottage immediately seemed cramped with Ran Sheng in it. It seemed that Ran Sheng could overturn the thatched cottage with just a stretch of his hand.
After Yu Xiao's father introduced him, Yu Yu said: "I heard that Chen Zuojian also studied astronomy and calendar. Do you know the similarities and differences between Gaitian theory, Huntian theory and Xuanye theory?"
The theory of Gaitian, the theory of Huntian, and the theory of Xuanye are the three most representative cosmologies in ancient China. The theory of Gaitian is the oldest. It is said that "the sky is like a lid, and the earth is covered by laws." It believes that the universe is a hemisphere.
The earth spreads out endlessly, and the sky covers the earth like a bucket——
The theory of Huntian, represented by Zhang Heng of the Eastern Han Dynasty, believed that “the Huntian is like a chicken, the heavenly body is round like a pellet, the earth is like a chicken with yellow inside, living alone in the sky, the sky is big and the earth is small, there is water inside and outside the sky, and the sky envelops the earth, just like a shell
Wrapped in yellow, the sky and the earth each stand up by the air, and float by carrying water." The theory of Huntian is a step further than the theory of Gaitian. It can basically reflect the celestial phenomena within the scope of the solar system. And because there is an armillary sphere as evidence, the theory of Huntian is China's
The most mature and complete cosmology theory in ancient times——
The system proposed that Xuan Ye was talking about Lang Ximeng, the secretary of the Eastern Han Dynasty, the ancestor of Xi Chao. Xi Meng believed that "the sky is without substance. Looking up at it, it is infinitely high and far away. The sun, moon and stars naturally float in the void, and they stop where they are."
They all need Qi. Therefore, the Qi Yao may pass away or live, may go along or go against it, see impermanence, advance and retreat differently, and have no root system, so they are different.”
It is said that it goes further, but due to the lack of strong evidence like the armillary sphere, it is not widely spread.
As a fusion of souls from two generations, Chen Caozhi not only had the advanced cosmology of later generations, but also read some astrology books in Gehong Taoist Temple in Chuyang. Verifying it with the common sense of later generations, it was natural to draw parallels. Yu Xi needed to study the "precession of equinox" for a lifetime.
"It didn't take him half an hour to understand the difference between a tropical year and a sidereal year.
Chen Cao said: "I have read Zhongning Gong's "An Tian Lun" in the collection of my teacher, Mr. Zhikawa. I think "An Tian Lun" is better than Gaitian theory and Hun Tian theory, compared with Xuan Ye
Go one step further."
Yu Xi and Ge Hong were similar in age, and they had quite a friendship. Twelve years ago, Ge Hong came to live by the Siming Lake for half a month, chatting with Yu Xi. Yu Yu was then working as a minister of cavalry in Beijing, and later when he returned home
Hearing what his brother said, Yu Xi believed that Ge Hong was the most knowledgeable person in the Eastern Jin Dynasty, so Yu Yu was surprised when Chen Caozhi said that Ge Hong was his teacher. He also heard Chen Caozhi praise his brother Yu Xi's "An Tian Lun"
”, the original ill feeling towards Chen Caozhi was reduced a lot, but he still thought that Chen Caozhi was just flattering, so he said: “Please elaborate on it.”
Chen Caozhi combined the theory of Hun Tian, Xuanye and An Tian, and used the astronomy knowledge he had mastered in his previous life to talk eloquently about the distribution and movement of the sun, moon and stars, the position of the earth, its rotation and revolution, the solar system and the Milky Way.
, the beginning and end of time and the boundlessness of space come calmly——
Yu Yu listened to it in vain at first, but the more he listened, the more strange and surprised he became. Under the influence of his brother, Yu Yu was not difficult to understand what Chen Caozhi said. Moreover, the Eastern Jin Dynasty was an era of active thinking and tolerance, and heresies and heresies could coexist.
, it is rare for someone to be punished for academic speech. When he heard Chen Caozhi use the gravity of the planet to explain the "precession", Yu Yu leaned forward and listened attentively. It can be said that he was arrogant at first and then respectful later. Although his brother Yu Xi discovered it.
The precession of "one degree in fifty years", but he knew it but didn't know why. He didn't understand why the phenomenon of precession occurred. Now he heard Chen Caozhi explain it by the mutual gravity of the sun, moon and stars, but Yu Yu didn't understand it.
, but I have to admit that Chen Caozhi’s fantastic ideas are unprecedented. Chen Caozhi’s description of the earth on which people rely for recuperation made Yu Yu and Yu Xiao’s father feel enlightened, novel and cheerful——
Yu Xiao's father asked: "Brother Chen, what is the example of the theory of five continents and four oceans?"
Chen Caozhi smiled and said: "There is no example. It will be verified after a long time."
There is no way to verify Chen Cao's uprightness, but with Yu Yu's knowledge, he knows that what Chen Cao Zhi said is a new theory of the universe after Gaitian theory, Huntian theory, Xuan Ye theory and An Tian theory.
Examples, but it is amazing to be able to conceive of such a theory and justify it!
Yu Yu was silent for a long time and asked: "Does Chen Zuojian think there will be a severe drought in Jiangdong in the next two years?"
Chen Caozhi responded: "Yes, and there will be a great epidemic after the great disaster. If Marquis Yu believed in the younger generation's words, he ordered the people to open lakes to store water. This should have been a precaution, which should be able to reduce the impact of the disaster. I have come to Kuaiji to review Tujuan. I have been
I would like to report to the Chancellor, Situ Mansion, please use the income obtained from this land check to build water conservancy channels this winter and next spring, so that tens of thousands of hectares of fertile farmland in Kuaiji can initially withstand natural disasters such as drought and floods."
Yu Yu was granted the title of Marquis of Pingkang County, so Chen Caozhi was considered the Marquis of Yu.
Yu Yu was silent again and asked Yu Xiao's father to take Chen Caozhi and Ran Sheng to have dinner first, and then go to Siming Mountain for some fun in the afternoon.
In the evening, Yu Yu invited Chen Caozhi to meet him again. This time he did not talk about astronomical calendars, but only about the monarchs and ministers since the Eastern Han Dynasty. Chen Caozhi had his own unique and insightful opinions on the gains and losses of politics and the rise and fall of aristocratic families.
, Yu Yu claimed to be elegant, good at classics and history, and rich in knowledge. He was listening to Chen Cao's talk at night, and suddenly he seemed to miss something.
That night Chen Caozhi stayed overnight at Yu's Manor. Before going to bed, Xiao Chan said: "Xiao Langjun, shall we go back to Shanyin tomorrow? The weather is getting colder every day, I'm afraid it's going to snow."
Chen Caozhi nodded and said: "Go back tomorrow." He thought to himself: "I have made it very clear to Yu Yu from the astrology and history. Supporting Tu Duan is a matter of destiny. If he still doesn't understand,
Then a strong blow must be made. I remember that Liu Yu, who proclaimed himself emperor fifty years later, executed the powerful Yu Liang of Kuaiji in the Yixi Tuduan. Yu Liang should be the grandson of Yu Yu. The tyrannical Yu family always
You have to bow your head."
On the morning of October 28th, Chen Caozhi said goodbye to Yu Yu. Yu Yu was surprised and said: "Chen Zuojian arrived yesterday, why did he leave today? Is it because I, Yu, are being negligent?"
Chen Cao said: "Yesterday, Marquis Yu gave me a lesson on classics and history. Cao Zhi was deeply enlightened. I wanted to ask for more advice, but I was busy with official duties and could not stay long. I will ask Marquis Yu for advice someday when I have time."
After Yu Yu heard what Chen Caozhi said, he stopped trying to persuade him to stay and asked Yu Xiao's father to see Chen Cao off on his behalf.
Yu Xiao's father took several servants to send Chen Cao out of Yuyao County. When leaving, Yu Xiao's father saw that Chen Caozhi had not asked about Yu's attitude towards Tu Duan, so he asked: "Brother Chen, what do you think of Yuyao's death this time?"
Is it worth it?"
Chen Caozhi smiled and said: "If you can meet Duke Shu Ning, you will gain something."
Yu Xiao's father smiled and said nothing more. He only said that he might go to Shanyin again in a few days.
Farewell to Yu Xiao's father, Chen Caozhi and Ran Sheng, more than 20 people, hurried on their way. The wind was cold and the breath turned into mist. It was quite cold when riding on the horse. Chen Caozhi went to sit on the bullock cart, but Ran Sheng was not afraid.
Leng, riding a big white horse next to Chen Cao's oxcart, said loudly: "Brother's mouth is dry after talking about these hundreds of miles. This Yu family just doesn't submit the matter of hiding out. According to me,
I might as well capture that skinny old man to avoid having to make another trip next time, but it’s a pity that my eighty sergeants have all stayed in Jiankang, and we are still too alone now.”
Chen Cao said: "Xiao Sheng, try not to solve the Tudu issue by force, otherwise I will become the enemy of the Kuaiji gentry."
Ran Sheng said: "But they refuse to hand over the hidden house, so we will have to use force in the end."
Chen Cao said: "Yu, Wei, Kong, He, I just want to deal with one family. I hope the Yu family will not be so ignorant of current affairs."
Ran Sheng said: "Then let's go back to Shanyin and inspect the He family's manor first, find out the hidden house and punish the He family for his crimes. The Yu family is naturally afraid."
Chen Cao said: "We have to wait until after the 23rd of the winter lunar month to conduct inspections."
Xiao Chan, who was in the same car, said: "Then we have to stay in Kuaiji for at least a month. Fortunately, Shanyin is not far from Qiantang, and we can get back in two days."
Chen Cao said: "You can always go back to Chenjiawu before the Chinese New Year."
The group braved the cold wind and arrived at the small town of Dongguan in Shangyu County on the afternoon of the 30th. Chen Caozhi asked Xiaochan and others to rest at the town inn, and he and Ran Sheng'er rode to Dongshan, twenty miles away.
Xie's Manor.
The sky was covered with thick clouds, the wind was as cold as a knife, and as we approached the Dongshan Pass, snow began to fall from the sky.
Ran Sheng was very happy and said: "The snow fell early this year, but the weather is not too cold today and the snow cannot accumulate."
Chen Cao said: "The weather is abnormal, or there may be a disaster."
The two of them walked for several miles along the left bank of the Shan River in the snow. On both sides of the Shan River were large tracts of pine, bamboo, and fir trees, which had not withered through the winter and were continuously green. There was a pavilion at the east mountain pass. It was Cao'e Pavilion. It was built in the third year of Shengping.
In summer, Chen Caozhi and Xie Daoyun met at this pavilion, and it was here that Chen Caozhi realized that Zhu Yingtai of Shangyu was Yongxu and Xie Daoyun——
Someone in Cao'e Pavilion saw Chen Caozhi and Ran Sheng approaching, so he walked down from Cao'e Pavilion and shouted: "Chen Langjun——"
Chen Caozhi slowed down his horse and took a look, but he was one of the eight Xie family soldiers brought by Xie Daoyun from Jiankang. This private soldier of the Xie family said loudly: "My husband is really right. I was ordered to do this."
We are waiting for Chen Langjun, but after only half an hour, Chen Langjun will arrive." This private soldier of the Xie family has become accustomed to calling Xie Daoyun "Langjun".
Chen Cao said: "Then I will wait for your husband in the pavilion, and you can go and report the news quickly."
The private soldier of the Xie family put on his bamboo hat and walked away. After walking a few steps, he came back and said, "I would like to inform Mr. Chen Langjun that Mr. Dai Andao of Yanxi came here from Shanyin yesterday and is still in the village."
Then he left in a hurry.
Chen Cao was stunned. Dai Kui and Dai Andao were the brothers of Dai Shu, the internal historian of Kuaiji. Xie Daoyun once studied piano and painting with Dai Kui. Naturally, Dai Kui had seen Xie Daoyun's true face. Now wouldn't Brother Yingtai's secrets be revealed?
? Since Mr. Diane was at the village, how could he not go to meet him?
Then I thought again, Xie Daoyun had people waiting here to tell him this, probably because he didn't want him to see Mr. Diane, lest he reveal the shocking secret of Xie Daoyun disguised himself as a woman to serve as an official.
