Although he is skinny, he is mentally winged. Eguanbo knelt behind the bookcase, willing to Chen Caozhi and Ran Sheng into the grass house one after another, Chen Caozhi was handsome and long, delicate and elegant, and Ran Sheng's body was like an iron tower, majestic, and the grass house had Ran Sheng in the immediately narrow, it seemed that Ran Sheng could overturn the grass house as soon as he stretched out his hand.

After Yu Xiao's father introduced him, Yu Yu said: "I heard that Chen Zuojian also learned the astronomical calendar, so can you know the similarities and differences between Gaitian, Hun Tian, and Xuanye?" ”

Gaitian theory, Hun Tian theory, and Xuanye theory are the three most representative cosmological theories in ancient China, and Gaitian theory is the oldest, the so-called "heaven is like a cover, and the earth law is overturned" believes that the universe is a hemispherical shape, the earth is boundless, and the sky is like a bucket covering the earth

Represented by Zhang Heng of the Eastern Han Dynasty, the armillary heaven theory is represented by Zhang Heng, who believes that "the armillary sky is like a chicken, the celestial body is round like a projectile, the earth is like a chicken in the yellow, living alone in the sky, the sky is big and the earth is small, there is water in the surface of the sky, the sky is wrapped in the earth, and the shell is wrapped in yellow, and the heaven and the earth stand by the air, carrying water and floating" The armillary theory is a step bigger than the Gaitian theory, which can basically reflect the celestial bodies and stars within the scope of the solar system, and because there is an armillary sphere as evidence, so the armillary sky is the most mature and complete cosmological theory in ancient China

The system proposed that Xuanye said that it was the Eastern Han Dynasty secretary Lang Xi Meng, the ancestor of Xi, Xi Meng believed that "the sky is qualitative, looking up at it, high and far, the sun and the moon and the stars, naturally floating in the void, its actions must be qi o is to Qiyao or pass away or live, or go or reverse, see impermanence, advance and retreat are different, since there is no root system, so they are different." "Xuanye Theory encapsulates the idea of the infinite universe, which is a step further than the armillary theory, but due to the lack of strong evidence like the armillary sphere, it is not widely spread.

As the fusion of the souls of the two worlds, Chen Caozhi not only has the advanced cosmology of the later generations, but also browsed some astrological books in the Ge Hong Dao Courtyard in the early balcony, which is verified with the common sense of the later generations, and naturally touches the bypass, Yu Xi needs to study the "precession" for a lifetime. It didn't take him half an hour to understand the difference between the year of return and the year of the stars.

Chen Caozhi said: "The younger generation has read Zhong Ninggong's "Antian Treatise" in the collection of my teacher Mr. Zhichuan, and the younger generation thinks that "An Tian Lun" is better than Gaitian and Hun Tian, and it is a step further than Xuanye Theory. ”

Yu Xi and Ge Hong are of the same age, the two have a good relationship, twelve years ago Ge Hong had come to live on the shore of Siming Lake for half a month, and Yu Xi chatted about the world, Yu pre-that fashion in Beijing for the free riding squire, and later when he returned to his hometown, he listened to his brother talk about it, Yu Xi thought that Ge Hong was the first erudite person in the Eastern Jin Dynasty, so Yu pre-heard Chen Caozhi said that Ge Hong was his teacher, and couldn't help but be surprised, and listened to Chen Caozhi praise his brother Yu Xi's "Antian Theory", originally Chen Caozhi's disgust was reduced a lot, but still thought that Chen Caozhi was pandering. Then he said: "Please try to discuss it in detail." ”

Chen Caozhi combined the theory of armillary heaven, the theory of Xuanye, and the theory of anti-heaven, and used the astronomical knowledge he had mastered in his previous life to talk about the distribution and operation of the sun, moon and stars, the position of the earth, its rotation and revolution, the solar system and the Milky Way, the beginninglessness and end of time, and the boundlessness of space

Yu pre-listened to it at first, but the more he listened, the more strange he became, the more he listened, the more shocked he became, Yu pre-was influenced by his brother, and it was not difficult to understand what Chen Caozhi said, and the Eastern Jin Dynasty was an era of active and tolerant thought, heresy and heresy could coexist, and few people were convicted for academic remarks. At that time, Yu pre-leaned forward and listened attentively, which can be described as a precedent and a compliment, although the elder brother Yu Xi appeared a precession of "one degree in fifty years", but he knew that he did not know why, and did not understand why there was a precession phenomenon, and now he listened to Chen Caozhi to explain the mutual gravity of the sun, moon and stars, Yu Pre did not understand this, but had to admit that Chen Caozhi's whimsical ideas were unprecedented, and Chen Caozhi's description of the earth on which the people relied to recuperate made Yu Pre and Yu Xiao's father really have a sense of novelty and cheerfulness

Yu Xiao's father asked: "What is Brother Chen's example?" ”

Chen Caozhi smiled and said: "There is no example, it can be verified after a long time." ”

Chen Caozhi's upright standing is unverifiable, but with Yu Qian's insight, he knows that what Chen Caozhi said is a new theory of the universe after the Gaitian Theory, the Hun Tian Theory, the Xuanye Theory, and the Antiy Theory.

Yu was silent for a long time and asked: "Does Chen Zuojian think that there will be a big drought in Jiangdong in the next two years?" ”

Chen Caozhi responded: "Yes, and there will be a big epidemic after the disaster, if the Hou Yu believes in the words of the younger generation, let the clansmen open the lake to store water, as early as a precaution, when the impact of the disaster can be reduced, I will now audit and review the land break, once played Shangshutai, Situ Mansion, please use the households obtained from the land break inspection for the construction of water conservancy canals this winter and next spring, so that tens of thousands of hectares of fertile land can initially resist drought and natural disasters." Small.

Yu pre-accepted the title of Marquis of Pingkang County, so Chen Caozhi was commensurate with Marquis Yu.

Yu Yu was silent again, and asked Yu Xiao's father to take Chen Caozhi and Ran Sheng to dine first, and then go to Siming Mountain in the afternoon to play.

In the evening, Yu pre-invited Chen Caozhi to meet again, this time not to talk about the astronomical calendar, only to talk about the Eastern Han Dynasty since the monarchs and ministers, Chen Caozhi has his own unique and incisive sub-understanding of the gains and losses of politics and the decline of the family. Yu pre-claimed to be an elegant and good scripture official, and he was rich and broad, and he listened to Chen Cao's conversation at night, and he suddenly lost something.

This night, Chen Caozhi stayed overnight in Yu's Manor, and before going to bed, Xiaochan said: "Xiaolangjun, will we go back to Shanyin tomorrow, the weather is as cold as a day, I'm afraid it will snow." Small.

Chen Caozhi nodded and said, "I'll go back tomorrow." Heart said: "I have made it very clear from the astrological and historical aspects that Yu pre-emptively supports the earth, if he still does not understand, then he must be dealt with a strong blow, I remember that fifty years later, Liu Yu, who was called the emperor, was executed in the Yixi Tu Break, and Yu Liang should be Yu Liang's grandson, and the Yu family always has to bow his head

Early in the morning of October 28, Chen Caozhi resigned to Yu Pre, and Yu Pre was surprised: "Chen Zuojian only arrived yesterday, why do you have to leave today, is it because of my Yu family's negligence?" ”

Chen Caozhi said: "Yesterday, the Marquis of Yu gave him a lecture on the history of the scriptures, and he was deeply inspired, and he wanted to ask for more advice, but he was on official business and could not stay for a long time, so he had time to ask Marquis Yu for advice in the future." ”

When Yu heard Chen Caozhi say this, he no longer kept it and asked Yu Xiao's father to send Chen Cao a ride on his behalf.

Yu Xiao's father took a few servants to send Chen Cao out of Yuyao County, and when he was leaving, Yu Xiao's father saw that Chen Caozhi had not asked about Yu's attitude towards Tuxuan, so he asked: "Brother Chen thinks that this trip to Yuyao has something to gain?" ”

Chen Caozhi smiled and said: "If you can see Shu Ninggong, you will get something." Small.

Yu Xiao's father smiled and didn't say anything more, only said that he might have to go to Shanyin again in a few days.

Farewell to Yu Xiao's father, Chen Caozhi and Ran Sheng more than 20 people hurried to hurry, the wind was cold, the breath turned into fog, and it was quite cold on the horse, Chen Caozhi went to the ox cart to sit, but Ran Sheng was not afraid of the cold, riding a big white horse and following Chen Caozhi's ox cart, and said loudly: "These hundreds of miles back and forth, Brother also spoke dryly, this Yu family just did not submit the matter of the hidden household, according to me, simply arrested the thin old man, so as not to run next time, but unfortunately my eighty sergeants have stayed in Jiankang, and now they are still walking through Yu Shishan Lonely." ”

Chen Caozhi: Xiao Sheng, try not to solve the matter by force, otherwise I will become the enemy of the Huiji clan. Small.

Ran Sheng said: "But they refuse to hand over the hidden household, we have to use it in the end." ”

Chen Caozhi said: "Yu, Wei, Kong, He, I just want to deal with one family, I hope that the Yu family will not be so ignorant of current affairs." Small.

Ran Sheng said: "Then we will go to Ming Shanyin to check the He family's manor first, and find out the hidden household to cure the He family's crimes, and the Yu family is naturally afraid."

Chen Caozhi said: "If you want to check it, you have to wait until after the 23rd of the winter month." ”

Xiaochan, who was in the same car, said: "Then we have to live in Huiji for at least a month, fortunately, Shanyin is not far from Qiantang, and we can rush back in two days."

Chen Caozhi said: "I can always return to Chenjiawu before the Chinese New Year." ”

Pedestrians braved the cold wind and hurried to Dongguan Town, Shangyu County in the afternoon of the 30th, Chen Caozhi asked Xiaochan and others to rest at the town inn, and he and Ran Shenger rode to Dongshan Xie's Manor twenty miles away.

The sky is covered with clouds, the knife is fast, the wind is as cold as a knife, and when it is about to reach the east mountain pass, the sky is actually snowing one after another.

Ran Sheng was very happy and said: "This year's snow is early, but the weather is not cold today, and the snow can't accumulate." ”

Chen Caozhi: "The climate is abnormal, or there may be disasters. ”

The two braved the snow along the left bank of the Thorn Creek and galloped for several miles, both sides of the Thorn Creek are large areas of pine, bamboo, shirts, not withered in winter, continuous and verdant, there is a pavilion wing in the east mountain pass, that is Cao E Pavilion, in the summer of the third year of Shengping, Chen Caozhi and Xie Daoyun met on this pavilion, that is, here Chen Caozhi understood that Shangyu Zhu Yingtai is Yongsu Xie Dao

Cao E led someone to the guide, and when he saw Chen Caozhi and Ran Shengchi approaching, he walked down to Cao E's Pavilion and called loudly: "Chen Langjun."

Chen Caozhi slowed down his horse and looked at it, but it was one of the eight Xie clans brought by Xie Daoyun from Jiankang, this Xie clan's private soldier said loudly: "My family Langjun is really expected, the villain was ordered to wait for Chen Langjun here, but in half an hour, Chen Langjun arrived." "This Xie private soldier is already used to calling Xie Daoyun Langjun.

Chen Caozhi said: "Then I will wait for your family Langjun on the pavilion, and you will report the news." ”

The Xie private soldier put on a hat, walked away, walked a few steps and came back and said: "I want to teach Chen Langjun to know that Mr. Dai Andao of Kexi came here from Shanyin yesterday and is still in the village. So he hurried away.

Chen Cao was stunned, Dai Yi Dai Andao is the younger brother of Dai Shu in the history of Huiji, Xie Daoyun once studied piano and painting under Dai Yi, Dai Wei naturally saw Xie Daoyun's true face, and now Brother Yingtai is not going to show his stuffing? Since Mr. Diandao is in the village, how can he not go to see him!

After thinking about it, Xie Daoyun asked people to wait here to tell him this, probably because he didn't want him to see Mr. Dai Andao, so as not to reveal the amazing secret of Xie Daoyun's disguise as a woman.
