People in Datang have been expelled from school

Chapter 540 The Worried Xu Jingzong
Before Li Zheng could open his mouth, Pei Xingjian said again: "But it makes sense for the teacher to measure the downstream river course. According to the meaning of the teacher's drawing, it is necessary to build a river embankment upstream. After the embankment is built, we must pay attention to the width of the downstream river course. To determine the height of the embankment, if it is not done well, it will easily cause flooding downstream."

Pei Xingjian's talent is quite high.

The relationship between the river course and the dam can be seen at a glance.

Li Zheng said to Pei Xingjian: "Actually, this is a small dam."

Pei Xingjian didn't know much about dams, but he could roughly understand the meaning by looking at the drawings, and said: "If this is built, it can not only be used for water storage, but also for storing water during floods and releasing water during droughts, which is really beneficial to farming. "

After speaking, Pei Xingjian put away the drawings and handed them to Li Zheng, bowing and saying, "Teacher, the students are willing to take someone to help the teacher measure the upper river."

Li Zheng still handed over the blueprint to Pei Xingjian, "I will leave this blueprint to you, just tell me if you need anything, and you will choose the construction site."

"This one……"

Pei Xingjian said hesitantly: "The students feel that they can measure the river course, but they may not have much experience in construction."

Li Zheng said with a smile: "What you learn on paper is superficial. You have to try everything before you gain experience. You have been studying in the academy and haven't practiced the knowledge you have learned. This is not good."

Seeing that Pei Xingjian was a little nervous, Li Zheng said again: "Well, you can ask Yan Liben to help you."

Pei Xingjian bowed and said: "The teacher told the students not to refuse, it's just that the students need something."

"Say."

Since Pei Xingjian has this idea, Li Zheng is of course willing to test how much ability these children have now.

These children can do simple mathematics, physics and chemistry. Li Zheng is confident that these children in his academy can solve all the problems in the nine chapters of mathematics.

There is also Li Chunfeng, a guy who keeps telling the children about math skills in the academy.

All kinds of calculations are now poorly applied and mastered by these children.

These children need to be given a chance to use their knowledge.

Pei Xingjian bowed and said: "Students feel that they need some classics in the imperial court. The students heard from Teacher Chu Suiliang's lecture that there was a man named Li Chun in the former Sui Dynasty. Guozijian, the students want these classics."

Li Zheng smiled and said, "No problem."

Pei Xingjian hugged the blueprint that was as tall as himself and said, "Teacher, please give the students some time."

"Okay, if you need anything, you can come to me with all your manpower and material resources."

Pei Xingjian nodded slightly and left.

Li Zheng stood where he was, feeling a little worried at the moment.

Land is not enough.

The more than 1 mu of land in Jingyang is not enough to squander.

If I don't rebel, all the land in the world is mine, that would be great, huh!Sure enough, it's beautiful and ruthless.

Back in the horse circle, Li Zheng spread out the land in Jingyang today. Now Niu Jinda's family's territory has been owned by him, and the land in the southeast of Jingyang has expanded to Cheng Yaojin's family.

It borders Cheng Yaojin's Shiyi fiefdom.

The east side of Jingyang River connects Dongling to Weishui.

The land where Weishui River and Jingyang River intersect is very good and fertile.

From east to west, the Weishui River diverges into two tributaries from Lintong, one is the Jingyang River in Jingyang.

One is the Bashui to the south of the Weishui River, and then branched out into several tributaries all the way west.

Looking at the water conservancy branch today, I have to say that the wisdom of the ancients is superb.

The Zhengguo Canal built by the State of Zheng went from the central part of the Guanzhong Plain to the north to the Neijing River in Zhongshan, opening up several river channels in Guanzhong.

It has created thousands of miles of fertile fields and benefited future generations.

It is a good idea to build a dam from the land of Gaoling, and there will be a Gaoling Reservoir in later generations.

Li Yifu came and said: "Chang'an Order, General Feng sent another 30 shi of old grain."

"Is everything handed over?"

"Okay, it's settled."

Li Zheng nodded slightly, pointed to the direction of Gaoling on the map and said, "Whose territory is to the east of us."

Li Yifu took a look and said, "That's Qin Qiong, the fiefdom of General Qin."

"General Qin Qiong..." Li Zheng thought for a while and said, "It seems that he is not very familiar with him."

Li Yifu smiled wryly, Chang'an Ling has been living in Jingyang for a long time, and of course he doesn't know many people well without going out of the village all the year round.

Li Zheng said to Li Yifu: "You sent someone to give you General Qin Qiong, saying that I want to buy his land."

Li Yifu nodded, "I will make arrangements here."

As soon as he left, Xu Jingzong came back, "Chang'an Order, something happened."

Li Zheng looked away from the map and said, "Tell me."

Xu Jingzong said in a low voice: "They started to check on Xinxin. After Changsun rushed to Yumen Pass, he immediately sent people to Tubo to meet Songtsan Gampo, and found out that Xinxin was found. Songtsan Gampo also told Changsun Chong about Xinxin. .”

Li Zheng sighed: "This eldest Sun Chong really doesn't stop."

Xu Jingzong nodded, "Chang'an Ling, what should we do next?"

"Pour me a cup of tea."

"what?"

Li Zheng said to Xu Jingzong who was a little astonished: "I said pour me a cup of tea."

Only then did Xu Jingzong come back to his senses and pour Li Zheng a cup of tea.

Li Zheng took the tea poured by Xu Jingzong, and it was almost summer, "The weather is getting hotter and hotter now."

Xu Jingzong said in a low voice: "Jingyang is not bad, but Chang'an is getting hotter and hotter, and many people are starting to stockpile saltpeter to make ice."

Li Zheng shook the fan in his hand and said, "Is the person still alive?"

"what?"

Xu Jingzong didn't turn the corner again.

Li Zheng said: "I mean, is Xin Xin still alive?"

"It should still be alive, and there is no news that it is still in Tubo."

Tired of chatting with Chang'an Ling, Xu Jingzong wiped the sweat from his forehead, "Now I'm afraid that Songtsan Gampo will hand over him to Changsun Chong."

After Xu Jingzong finished speaking, he looked at Li Zheng's expression.

There seemed to be no tension at all.

Even a little calm.

Li Zheng said: "Did you do everything clean when you bought your favorite?"

Xu Jingzong bowed and said, "Chang'an Ling can rest assured that Xin doesn't know anything, even the Minister of Taichang Temple doesn't know that he is the one who bought it."

"It's all yours to do. Even if you find out, it's your business. It shouldn't have much to do with me." Li Zheng said.

"I am loyal to Chang'an Ling, and I have always had no second thoughts." Xu Jingzong said immediately.

"I haven't said anything yet, why are you so nervous?" Li Zheng said.

"Really?" Xu Jingzong wiped the sweat from his forehead again.

The summer has not yet fully entered, and the Jingyang area is good, even if it enters the summer, it will not be too hot. It is a good place to escape the heat, especially since there is a forest around Jingyang as a barrier.

Xu Jingzong sat under the shade of a tree and said, "Chang'an Ling, now I'm worried whether Songtsan Gampo will let go."
