Li Xun was moving very quickly. The next day, someone sent people to bring mud and sand and gravel. Looking at the truckloads of sand and gravel, Li Zheng said to Li Yifu: "Try all these sand and gravels to the entrance of the village to Yan Liben."

The person who brought the sand and gravel was also from the Li family in Zhaojun. After Xu Hui paid the money with the account book, the transaction was completed.

Xu Hui said: "Chang'an Order, the person who came said that there will be sand and gravel in the future. I asked us how much more we want."

"Let them continue to transport first."

"Understood."

The visitor also left with his own hands.

The villagers at the entrance of the village were transporting sand and gravel. When Li Daxiong saw his son sitting lazily on the side of the road, he had to say that he didn't feel very comfortable seeing his son so lazy.

Li Zheng also noticed Li Daxiong and saw him sitting beside him and said, "Now the slack season, why don't you find a refrain for you?"

When Li Daxiong heard this, he wanted to slap him, but he also thought that the child was so old and had already married a wife.

He had to take back his movements, and Li Daxiong whispered: "You don't have to worry about being a father."

Seeing that Li Zheng was still looking at the busy villagers, Li Daxiong said again: "You kid is capable now. Many people come to you to do business, and many people want to curry favor with you."

The wind under the shade made people feel very comfortable. Li Zheng supported his chin with one hand and said, "I know what those people are thinking, and I will be on guard."

Li Daxiong sighed a little and said, "The days were hard at the beginning, but now they are better. We used to be poor."

Li Zheng nodded and said, "I understand that we used to be poor families, and we must be thrifty and not forget the hardships and simplicity."

Li Daxiong said again: "The old village chief said that you are rich and powerful now, and you are also a county magistrate. Such a big man will naturally be respected."

Li Zheng smiled bitterly and said, "What do you think? I really want to return this position to Your Majesty."

Li Daxiong looked worried, "Now the old village chief and the aunts in the village, what you are most worried about is that you are floating around. Some people will forget who they are and do things they shouldn't do once they have power."

"Don't worry." Li Zheng patted Li Daxiong on the shoulder and said, "I'm saving money now. I'll find you a girl to re-string."

Li Daxiong: “…”

Li Zheng asked again: "What flavor do you like?"

Sometimes I feel that my son is good, and sometimes I feel that this kid is too uncontrollable.

Li Daxiong stood up and walked towards the village.

"Why are you wearing an old face today?" Li Zheng frowned and murmured to himself.

After Li Yifu made arrangements, he let out a long breath and sat under the shade of the tree. "The Chang'an Order has been arranged, and it will be used after Yan Dajiang returns from Chang'an."

Li Shimin was observing the printing factory, and Zhang Gongjin was introducing the assembly line beside him.

The assembly line is not difficult to understand, and the printing technology does not seem very difficult.

Looking back and forth, Li Shimin whispered: "It looks simple, but it's not easy to do."

Zhang Gongjin said: "It is true that as Your Majesty said, the distance between each thing and the right transmission must be achieved through repeated experiments. It contains a lot of mathematical knowledge. If one inch is not enough, one inch will also cause the entire assembly line to fail to operate."

Li Shimin looked at it and said, "Magic skills? Li Chunfeng said that Li Zheng's math skills are extremely high."

Zhang Gongjin nodded, "In Li Zheng's words, this is knowledge. Knowledge can change many things, just like the printing technique in front of you is knowledge that makes printing books so fast."

Hearing this, Li Shimin nodded and said, "Wisdom can often change many things."

Following Li Shimin out of the printing factory and heading towards Jingyang Academy, Zhang Gongjin said again: "Your Majesty, I still can't understand some things."

"A person as wise as you, and something you, Zhang Gongjin, can't understand?"

Zhang Gongjin smiled bitterly and said, "Your Majesty, I am also a teacher of Jingyang Academy, but Jingyang Academy seems to be different from the academy we know."

When he came to the edge of the academy, Li Shimin could hear the sound of reading aloud, "How is it different?"

Zhang Gongjin took Li Shimin into the academy and came to his office. Every teacher in the academy has his own independent room.

He took out a book, Zhang Gongjin turned the book and put it in front of Li Shimin, "Please read your Majesty."

Li Shimin looked at the page that Zhang Gongjin pointed to, which read a question, "Xiao Gang's family planted five fruit trees, and this year they harvested a total of 215 stones of fruit. There are four fruit trees that harvest an average of 45 stones of fruit each, and how many stones of fruit the other one collects?"

After reading this question, Li Shimin took a deep breath, "Is this a math problem?"

Zhang Gongjin nodded.

After reading the question several times, Li Shimin began to think about the difficult math problem.

Zhang Gongjin said: "This is a question that our academy children are about ten years old."

Li Shimin looked at the question and then looked at Zhang Gongjin, "Do you say that a ten-year-old child can calculate such a question?"

Zhang Gongjin nodded, "If you say that according to ordinary people's understanding, such mathematical problems are not the same as adult men, but the children here have already used algorithms to perfection."

Li Shimin took a deep breath again, "Perfect? ​​If you really want to say this, the children who come out of Jingyang Academy in the future will be masters of mathematics?"

Zhang Gongjin said with a sad face: "I think this is not the case. The question Your Majesty just looked at is just a question done by ordinary children. In the academy, Li Chunfeng has several children with very high talent in logarithmism. These children may achieve higher future achievements than Li Chunfeng."

"This Jingyang is really a brilliant place."

Li Shimin sighed.

Zhang Gongjin whispered: "I think this is not a talented person, but a different way of teaching. The earliest master in Jingyang was Li Zheng, and Li Zheng taught the earliest batch of children, that is, the big nun, and the children afterwards were all teaching younger children in the way Li Zheng."

"What is different from ordinary people is that the way of thinking and learning used in teaching is like mathematics. In the study of mathematics, most children can flexibly use mathematics in three years."

After saying that, Zhang Gongjin turned another page, pointed to a table and said, "Your Majesty, please look at this table."

Li Shimin read it for a long time. There were many numbers written on this table, but he couldn't understand what it was, but he couldn't say that I couldn't understand it.

Zhang Gongjin said: "This is a multiplication formula table. As long as you remember this multiplication formula table, children can do questions flexibly, add ninety-nine to multiply. Such complex operations Li Zheng can use only one table to quickly learn the most basic operations of mathematical techniques. Ordinary children need to spend several months or even half a year to learn, and children here may learn it in just a few days."
