Zhou Nan looked at Yu Zhongwen suspiciously, Yu Zhongwen pointed to Yu Shen beside Yu Min, and said: "If the children and grandchildren have the ability, they can earn the family business with their ability, if they have no ability; If even their own family business is harmed, they dare not let it out to harm the people of a state and a county. It is my grandson who suffers from the little old man. ”

Zhou Nan smiled and said, "What's so difficult about this? If Sun Ruo writes first-hand articles, he can go to the test for fame; If you are accustomed to galloping horses and arrows, you can go to the army to make a name for yourself, and you can also glorify the lintel. I don't think Ling Sun is a dull person, so why is Lord Yu worried? ”

Speaking of this eldest grandson Yu Shen, Yu Zhongwen vomited bitterness: "I don't know, my grandson has been smart since he was a child, but he doesn't like serious learning, he just likes the study of a hundred schools, and he reads some books such as mathematics, geography, and water classics. It's really not a good job. ”

Seeing that Yu Zhongwen accused himself of playing in the landscape, Yu Shen, who had been silent just now, blushed and said: "Big daddy, my grandson is not playing, but going to Wuzhong to find the "Wumen Water Conservancy Book". ”

Yu Zhongwen stretched out his hand to Zhou Nan, and said helplessly: "The matter of water conservancy has also been written into a book, and it can make my grandson take the risk of going, which is incomprehensible." ”

Zhou Nan asked Yu Shen with interest: "Can you find this "Wumen Water Conservancy Book"? ”

Yu Shen saw that Zhou Nan did not mean to demean him, so he said seriously: "The Book of Water Conservancy of Wumen is the experience of Zheng Lang Zheng Langzhong in the Southern Dynasty in his life, I just heard about it from others, and I was curious, so I thought about going to the Southern Dynasty to find Zheng Langzhong's descendants and seek a look at this book." After traveling to many places, he finally found the descendants of the Zheng family in Kunshan County, Pingjiang Prefecture, and his family saw that I sincerely begged, not only to borrow the "Wumen Water Conservancy Book" from me to copy, but also to explain more than me, which was really worth the trip. ”

"Listening to the title of this book, it must be a book on how to dredge rivers and canals and improve waterways, right?" Zhou Nan tried hard to think about it, but he didn't come up with the character of Zheng Kang in the Northern Song Dynasty, maybe he was still lonely and unheard, right? However, I am very interested in the Yu Shen in front of me, at the age of seventeen or eighteen, he dares to sneak to a neighboring country, looking for people and books, and he is not small, and he is not like a gentleman.

Not only that, Zheng Langzhong's book on water conservancy records more than 200 rivers, and he also recorded his lifelong experience in water control. The most admirable thing is that water control is not only about water control, but also about water and field as a whole, and put forward the theory that water control is the foundation of water control and field management. If I hadn't read this book, I would have thought about it for the rest of my life, but I'm afraid I wouldn't be able to think of such incisive words. When it came to water conservancy, Yu Shen, who was still a little restrained just now, said it like a river.

"Why is water control the foundation of land management?" As soon as Zhou Nan heard the word Zhitian, he immediately asked.

"If you don't control the water, and when a big flood rushes over, the river water rises on top, and the river bank collapses and sinks to the bottom, this is because the water destroys the fields. And if the people who control the water do not understand this truth, and only think that the river sand is silted up at the bottom of the river, and think that the river should be dredged so that the river can be drained, this is not clear to see the crux of the problem. Yu Shen said eloquently.

"It seems that this Zheng Langzhong does have a deep understanding of the method of water control." Zhou Nan was also impressed by this Zheng Kang's theory, what era is this? Being able to see the root cause of the problem of soil erosion and be able to propose solutions to it is quite remarkable in this era.

"There is a person named Shen Kuo in the Southern Dynasty, how is this Zheng Kang on water control?" Zhou Nan couldn't help but think of the great scientist Shen Kuo of the Northern Song Dynasty, Shen Kuo can be called the most outstanding figure in the history of Chinese science, but he is not in vain, he has made achievements in astronomy, square chronicles, legal calendars, music, medicine, divination, water conservancy, etc.

"Shen Mengxi is just dredging the Bianhe River and renovating the Shu River, and there is nothing outstanding, but Zheng Langzhong is a large area of Wushui that is governed, and he has summed up six ways to control water and seven fields." Yu Shen did not directly judge the achievements of the two, but in his tone, he could hear the respect for Zheng Yan.

"These two are both talented scholars of the Southern Dynasty, how can you be a yellow-mouthed kid who arbitrarily praises and criticizes?!" Yu Zhongwen finally couldn't help it, and shouted.

Yu Shen saw his grandfather speak, and immediately stopped talking. I don't know if it's unconvinced, or if it's always the same.

"Hehe, it's okay, Ling Sun is also straightforward." Zhou Nankuan explained.

"At such an age as a colt, he has such a great cause. My grandson still doesn't know what will happen in the future, which really hurts the little old man. Yu Zhongwen sighed again.

"If Lord Yu is willing, how about handing over his grandson to me? You also know that there are many people around me who are dancing knives and guns, and there is a lack of a secretary who can write for me. Zhou Nan said suddenly.

"If the horse is willing to discipline the little old man, the little old man will be grateful." Yu Zhongwen is not stupid, he originally wanted to introduce Yu Shen to Zhou Nan and let Zhou Nan arrange a suitable official position. If he asks directly, even if Zhou Nanken agrees, he will not have any good position. Therefore, Yu Zhongwen thought of such a family banquet, so that Zhou Nan could see Yu Shen and use his talents, in that case, it would definitely be better than Yin Feng's official position. Who would have thought that as soon as Zhou Nan opened his mouth, Yu Shen would follow Zhou Nan's side, and of course Yu Zhongwen couldn't ask for it - everyone knew that it was much better to be a person by Zhou Nan's side than to arrange an official position.

Zhou Nan peeked at Yu Shen, and saw that this Yu Shen was not full of expectation, so he deliberately said to Yu Zhongwen: "It's just that I go around fighting and sleep and eat indefinitely every day, so that Sun can grow up in a rich family, with fine clothes and jade food, and I don't know how hard Sun Ke will suffer?" ”

Yu Zhongwen Bai Zhounan's intentions also said: "Little Lao'er should also ask the horse to take care of it, if you suffer from some cold, you must delay the medical treatment in time." ”

"The king of horses, although I was born in a rich family, I have traveled thousands of miles, suffered from cold, heat, hunger, and hunger, and I can bear it myself!" The young and vigorous Yu Shen was so angry that Yu Zhongwen and Zhou Nan sang and harmonized, and said to Zhou Nan.

"Since you say that you can bear it, I will make up with you: if you can't bear it, you can come back, but from now on, you have to be honest at home, rely on your eldest father to ask for the title for you, and allow you to be an idle official, and live this life, don't talk about Wumen water conservancy, and be ridiculed by others to be shallow in learning." Yu Zhongwen saw that Yu Shen took the bait, and deliberately said something to stimulate Yu Shen, so as to strengthen Yu Shen's determination.

"If the grandson can't come back from hardship, don't say that he is an idle official, even if he is at the gate of Yufu, he will not have the face to enter again!" Yu Shen said proudly.

"Wait for tomorrow morning, you will go to the Metropolitan Governor's Office to see me, and follow me to Wuqing."
