Time flies, time flies.

Cheng Yun has been in Luoyang for a year, and he is very familiar with Cao Cao and others, Cao Cao and others are also studying in the Dongguan class, but they belong to the kind of fishing for three days and drying nets for two days, I have to say that the students of Dongguan are not the same as the students, the students of Dongguan are all officials and small families, for example, Cao Cao is entrusted with Cao Song's blessing, otherwise he would not have the opportunity to enter Dongguan.

The two brothers of the Yuan family don't say whose blessing they owe, there are too many big officials in the family to talk about it, the fourth and third dukes.

Others like Hongnong Yang's family, there is a person named Yang Fu who is quite talented, just bright and upright, and he will speak outright, and he is magnificent. In the Guo family in Yingchuan, there is a person named Guo Tu who is also a little capable, but he is too cynical, and often discusses current affairs with Yang Fu and others, and Cheng Yun doesn't like him very much. Taiwei Xu Xun's clan Xu You is a native of Nanyang, and he was recruited to Dongguan to study because of his intelligence, although Xu You is talented, but this person has shown an extraordinary fanaticism for wealth since he was young, and he is also very arrogant, Cheng Yun is very optimistic about him. Xu Shao and Xu Jing, who were favored by Cheng Yun, did not accept the invitation of the academy because they were ashamed to be in the company of people like Xu Xun who were in collusion with eunuchs.

On November 17, Cheng Yun was reading a book by himself, and Lu Min came to call him, it turned out to be the full moon of Cai Yilang's family, and Lu Zhi asked him to go too. Although he and Cai Yong do not have the name of master and apprentice, they have the fact of master and apprentice, and his calligraphy was not good before, but after Cai Yong's training, he is not much inferior to Lu Zhi now. As for the rhythm, it can only be said that there is no problem with appreciation, but if you want to say that you can get started, the playing is far inferior to Le Ji, which is too far worse than Cai Yong and Yang Biao. After studying for so long, it's like learning in vain.

I have to say that Cai Yong is Cao Cao's teacher, which surprised Cheng Yun, he had no impression of this matter before.

Hearing that Xiao Caiyan was full moon, Cheng Yun bookmarked the book, said to the administrator to borrow the book, and took the book back to Lu Min's mansion first.

Lu Zhi and others are ready to go, Cheng Pu is also there, although Cheng Pu is an official who belongs to Lu Zhi, but Cai Yong and Lu Zhi are at the same level, and they can be regarded as Cheng Pu's boss.

This time I went to Cai Yong's house, and I didn't take Tian Yu and Cheng Zhi with me, because Cai Yong didn't teach the two of them, these two people mainly studied with Huangfu Song Huangfu Shilang, but in the summer, Huangfu Song moved to the north to be the Taishou, and the two of them transferred to study with Lu Zhi, but Lu Zhi didn't have much time to teach, so the two always ran to Guanglu Temple, Dong Zhao and Xu Shu had no choice but to replace the teacher to teach the younger brother, and the martial arts did not fall behind, not only Cheng Pu personally taught, but also Xu Rong and Zhang He helped to teach.

Cai Yong is a well-known Confucian in the sea, and there is an endless stream of guests at the door of his daughter's full moon, even if he is a regular servant, there are people who come to congratulate.

Among them, Cheng Yun was very interested in Bi Lan in the court, a few days ago Bi Lan made a lot of useful and useless things to please the emperor, one of which is called the overturned car thirsty Wu, which is used to draw water from the river to moisten the road with a kind of waterwheel, saving the people from sprinkling water, just placed not far from Cheng Yun's house, Cheng Yun also deliberately observed the structure of the waterwheel, the overturned car can be driven by hand, foot, ox turn, water or wind. The keel blades are used as chains, lying in rectangular long grooves, and the body is inclined to the river or pond. The lower sprocket and part of the body were submerged in the water. When the sprocket is driven, the blade rises along the trough and sends the water out to the upper end of the long trough. In this way, the continuous circulation can transport the water to the place where it is needed, and the water can be continuously taken in, the efficiency is greatly improved, the operation and handling are convenient, and the water intake point can be transferred in time.

Don't you pay attention to these things, in this era when even sandstorms can't scrape Sizhou, there is a use for sprinkling water on the road?

This overturned thirsty black can be irrigated! It can be drained!

Isn't it because the people of the Eastern Han Dynasty are not living because of a year of drought, followed by a year of flood, and then a year of drought? Drought and flood cycles, what kind of soil quality can not guarantee a bumper harvest, so ah, this rollover is very promising! A must-have artifact for agricultural governance!

But this Bi Lan is really not a good thing, the economic collapse of the Eastern Han Dynasty has a lot to do with him, the Eastern Han Dynasty used five plants, and as a result, he made four plants, resulting in excessive money issuance and inflation, although Cheng Yun does not know much about economics, but it does not affect him at all to know that excessive inflation and excessive deflation are extremely harmful!

Cai Yong greeted the guests at the door, smiling, although it was a daughter, but Cai Yong didn't mind at all, Cai Yong has always been very good to Mrs. Cai, even the concubine was not accepted, pregnant for nine months, Cai Yong spent most of the time in Dongguan School, so he was very fond of the mother and daughter.

In front of Lu Zhi and them, it happened to be Lu Qiang, although Lu Qiang was also a eunuch, but there were few eunuchs who were talented, honest and honest, and Emperor Ling wanted to make him a marquis, but he refused.

Lu Zhi didn't say hello to Lu Qiang, Lu Qiang just came to give gifts in person, and went back after greeting Cai Yong, he didn't want to affect the atmosphere of the full moon banquet, with him, there were always angry young people who would say something out of place.

Cai Yong sent Lu Qiang away and hurriedly welcomed Lu Zhi in, Cheng Pu and the others were just by the way, there was no way, there was not much friendship between the civil and military.

The place where Lu Zhi and Lu Min sat with Cheng Pu Cheng Yun was not next to each other, after all, in ancient times when the class was very clear, trespassing was a crime, and those who were too would be killed.

Cheng Yun and they sat on the outermost part of the official area, after all, Cheng Pu relied on Cheng Yun's face to become a guest, so he belonged to the smallest guest in the official position, and next to them were the major wealthy families, the kind that did not serve in the imperial court, Hedong Wei's family, Hanoi Sima family, and Taishan goat's family were among the representatives.

In terms of influence, Hedong Wei may not be as good as Yingchuan Xun and Runan Yuan, but when it comes to wealth, Hedong Wei dares to admit the second, and only the Zhongshan Zhen dare to admit the first, so when it comes to it, Wei sits at the top of the merchant district.

Cheng Yun was originally bored, but a young man next to him came in with a peer and sat down, so he couldn't stay idle and began to harass his friends.

"Hey, boy, what's your name?" Cheng Yun quietly approached his little friend, "I'm Cheng Yun Cheng Wenying, a native of Liaoxi, and now studying in Luoyang." ”

The young man smiled shyly, "I've seen Wen Ying, my name is Wei Ning, and I haven't taken the table word yet, which makes Wen Ying smile." ”

Cheng Yun was stunned for a moment, and hurriedly asked, "But the son-in-law of Mr. Hedong Wei's uncle?" ”

Wei Qi, who was pondering something, came back to his senses and said with a smile: "Mr. don't dare to be, I am indeed Wei Qi, this is the dog Wei Ning."

Cheng Yun exchanged a few polite words with him, and his eyes staring at Wei Ning changed, fortunately, he covered it up well, and was not discovered by Wei's father and son, I have to say, this is really learned from Cao Cao.

After chatting with Wei Ning again, Wei Ning found that Cheng Yun was not in the right state, and hurriedly asked, "Wen Ying, is he not feeling well?" The face is not very good. It's a lot like when I'm not feeling well. ”

Cheng Yun grinned, "Yes, suddenly a little uncomfortable, I'll go to Gong, and I'll be better when I come back in a while." ”

In his heart, he scolded Wei Ning for being a bloody dog, who is like you Hedong Wei Zhongdao when he is uncomfortable, you are a tuberculosis ghost, I am worried that you are a tuberculosis ghost!

Today is Cai Yan's full moon, and the head of the Hedong Wei family came over with his eldest son, obviously the rhythm of proposing! Cai Yan wants to marry Wei Zhongdao, a tuberculosis ghost, be a widow, be robbed out of the plug, and then remarry?

Huh?

Why do you say again?

Cheng Yun's eyes were bright, worried about the butterfly effect and gave up on changing history, he didn't know if history would regret it, but he knew that he would regret it!

Cheng Yun also thought about it during this time, pinched all kinds of time nodes, and always wanted to find a suitable time to turn the tide and change history, so that the Han could continue to continue.

However, although he used to be an archaeologist, he did not have such a deep memory of history, he may be able to remember who the emperors of each dynasty were, and even what the era names were, but it is impossible to say that he can remember all the events, and even historians have to consult the information, let alone archaeologists.

He can remember these people in the Three Kingdoms, and they are all blessed by the Romance of the Three Kingdoms on TV, although the novel Romance of the Three Kingdoms has a very strong literary color, but the characters are still not too fictional.

Except for the Diao Chan that Cheng Yun longed for very much, which really can't be found in Wang Yun's mansion, there are other things that seem to be remembered, what Lu Zhi, Zhang Bao, Cao Cao, Cai Yong.

He has not forgotten the big guitar in Jiazi World, seeing that there are less than seven years, and he did not plan to intervene in advance of the Yellow Turban Uprising, without the Yellow Turban Uprising, the Ten Standing Servants could not be eliminated. If you want to cure the sores on your body, you must first dig out the rotten flesh inside before applying medicine and bandaging.

Moreover, before the Yellow Turban Uprising, there would be a relative He family who would make trouble, and they would also have to find a way to solve it, so that it would be more difficult to find an accurate time to do it.

However, it is better to solve the immediate problems first.
