Li Chengqian looked at the two absolute confidants standing in front of him and spoke directly here.
"Master Wei, Master Li, and the emperor agreed to the arrangement we just made.
Li Ke managed the Huai River, Li Tai managed the river, and as for Gu, I went to control the river. I wonder if these two gentlemen have anything to teach them? "
Wei Zheng stroked his beard after Li Chengqian finished speaking.
"His Royal Highness the Crown Prince is kind. As long as he conducts benevolent government, I believe that even if there is a slight problem, he will not be blamed by His Majesty."
But as soon as Wei Zheng finished speaking, Li Chengqian was stunned.
"What you said is the same as what you didn't say. What does it mean?"
But before Wei Zheng could explain to Li Chengqian again what was going on, Wei Zheng started talking here again.
"As for the management of rivers, Wei accidentally understood that the champion should be allowed to make suggestions for His Highness. What do you think of the champion?"
After Wei Zheng just finished speaking, Li Chengqian and Wei Zheng looked at Xu Yunyan at the same time, waiting for Xu Yunyan's answer. After Xu Yunyan scratched his head, he looked at Li Chengqian and Wei Zheng and started talking again.
"Your Highness, Mr. Wei, although I have been awarded the title of Champion Marquis, I know very little about managing rivers.
Although we have seen some methods of river management from some ancient books, we can only come up with innovations in this method of river management. "
After Xu Yunyan finished speaking, Li Chengqian nodded.
"Yes, Master Li has told me that as long as we manage the river, we must build dams on both sides of the river no matter what. Plant towering trees on the dams, strengthen the dams, and at the same time strictly control the quality during the dam construction process, so that no problems can occur. Anything to cut corners.”
Just as Li Chengqian finished speaking, Xu Yunyan started talking here again.
"Actually, the easiest way for the river here is to stop the sediment from upstream from rushing into the river. This requires large-scale afforestation to stabilize the sediment. However, in this case, it will inevitably encroach on a lot of farmland. It is human nature to be able to produce crops close to rivers, so afforestation may not be easy to achieve."
But as soon as Xu Yunyan finished talking about his worries, Wei Zheng smiled.
"Why does the champion think so? Now that we have auspicious seeds, we in the Tang Dynasty are not short of any food. As for the river, it is indeed easy to get water, but the water in this river is not as good as the Jiangshui and Huaishui. There is no one near the river. Those who plant fields, if they get too close and the water floods, all their fields will be gone, so most of them plant their fields far away.”
When Wei Zheng said this, Xu Yunyan's eyes lit up.
"This is feasible. Not only can you plant wood, but you can also plant some fruit trees and distribute them to nearby villages for them to take care of. However, the felling of these trees can only be confirmed by the government. Once the first level reports are reported to His Highness, His Highness can We know how the trees are growing, and we can arrange whether to replant them, etc.”
What Xu Yunyan said is very appropriate, and Li Chengqian also carefully recorded it here. If it can really remove all the sediment in the river and make it a clear river like the Jinghe River, it may not necessarily benefit the world.
Xu Yunyan nodded and looked at Li Chengqian talking here.
"This river is easy to freeze in winter. When it freezes, people need to break the ice on the river. We can't let them destroy the dam that was built with great effort. At the same time, we can also bury some pipes on the dam to divert the river water in. Other areas without water.”
When Xu Yunyan said this and then talked about the production of pipes, Li Chengqian and Wei Zheng's eyes lit up.
"This is a beautiful thing. Although the river has a lot of water, many places are still short of water. If the river water can be diverted to one place without water through this pipeline, it will be really a good idea. Method."
Li Chengqian looked at Wei Zheng's eyes and said here.
"Master Wei, I would like to trouble you to see how much money I still have in the East Palace. With half of it, I will first build several workshops for producing pipes.
Sir, I have produced a batch of pipes. Forget about other things, I will first test the location of the nearest river to see if it can divert water to Guanzhong. There are many places in Guanzhong that are short of water. "
When Li Chengqian said this, Wei Zheng hurriedly clasped his fists in response, and then ran out. As soon as Li Chengqian finished arranging Wei Zheng, he looked at Xu Yunyan.
"Master, don't you know if you have anything else to teach you?"
"In fact, the simplest way is to mine rocks to strengthen the dam, but mining rocks will cost a lot of money."
"It doesn't matter, it doesn't matter."
Li Chengqian waved his hand, "Not to mention other things, don't we have a lot of prisoners of war sent from Dongzhou? Just let them mine rocks and do such a thing."
Li Chengxian's words made Xu Yunyan's eyes shine.
"Yes, there is still a hostile force in the north, and that is the Western Turks. As long as we defeat the Western Turks, we will get a lot of labor to mine rocks to strengthen the dams and build the foundation for eternity."
The more Xu Yunyan thought about it, the more excited he became, and at the same time he looked at Li Chengqian and started talking.
"His Royal Highness the Crown Prince can also expand the Tiance Guards and place these troops in the mountains. As long as someone is mining rocks here, there must be troops stationed here to prevent Xiaoxiao from taking the opportunity to cause trouble or steal the rocks.
At that time, the newly formed army, like the Tiance Guards, would have a place to be placed, and His Highness the Crown Prince could pull it out of the mountains in an instant when needed.
Moreover, today the Cewei army is occupying the mountains and forests, so those robbers who are gathering in the mountains and forests will have to think carefully about it. Every dangerous place is controlled by me, the son of the Tang Dynasty. It will be impossible for the Tang Dynasty to have those robbers who are gathering in the mountains and forests. "
The more Xu Yunyan talked, the more excited he became. He kept gesturing about what it would be like when there were no robbers in the world and no people picking up things on the road. Li Chengqian also looked at Xu Yan with bright eyes.
But Li Chengqian looked at Xu Yunyan and suddenly the topic changed.
"Master, are there still some stones in the mountains that can be used to make lime?"
When it came to Lime Head, Xu Yunyan immediately had an idea.
"By the way, lime can be used to strengthen the dam when building the dam."
But when he talked about this lime, Xu Yunyan's eyes lit up again.
"You can also bake cement."
"Cement? What is this?"
Li Chengqian was in a daze here, while Xu Yunyan looked at Li Chengqian and said with a smile.
"Your Highness, cement is indispensable for making pipes."
Li Chengqian was a little at a loss. He had never heard of cement.
Xu Yunyan then told Li Chengqian how to find stones and clay and make cement.
Li Chengqian was a little confused after Xu Yunyan said that using stones to make cement would be stronger than the original stones after solidification.
"Is this really okay?"
But as soon as Li Chengqian said this, Xu Yunyan started explaining next to Li Chengqian.
"By the way, Your Highness, neither the pipes nor the cement that is about to be tested can be made of wood. Instead, the charcoal for making glazed glass should be found between Hedong Road and Hebei Road."
As soon as Xu Yunyan finished speaking, Li Chengqian nodded.
"This coal is located on Hedong Road. It has been discovered somewhere. Don't worry, master. Cheng Qian will definitely arrange for prisoners of war to mine it."
Li Chengqian was good at everything. When it came to the need for labor, he was a prisoner of war, exempting Datang
(This chapter is not finished yet, please turn the page) The sons and daughters are suffering and tired.
At this, Xu Yunyan nodded with satisfaction, "This will help His Highness the Crown Prince."
Immediately, Xu Yunyan explained the cement and pipe making process in detail to Li Chengqian. In any case, one person could not master them all. They could only focus on one task at a time until everything was mixed together to make cement.
Otherwise, if this thing is leaked out and used by the forces hostile to the Tang Dynasty to build cities with cement, wouldn't this increase the chance of damage to the sons of the Tang Dynasty in vain?
After Xu Yunyan finished talking about the cement production process, Li Chengqian looked at him with bright eyes.
"Don't worry, Master. I will arrange for people to test the production of cement now. If the production is successful in the next day or two, I can use it to present it to my father. It can also be regarded as adding a highlight to the collective wedding."
Xu Yunyan did not expect that Li Chengqian would think so, and looked at Li Chengqian clapping his hands and applauding.
"His Royal Highness the Crown Prince has considered everything properly. The general has not considered these things and still wants His Highness to raise some points. It is really the General's fault."
After Li Chengqian was satisfied, Xu Yunyan finally had the opportunity to express his wish to say goodbye and go home to Li Chengqian.
But Li Chengqian looked at Xu Yunyan a little reluctantly.
"Master, why don't you stay in the East Palace for a while? Wait until all the materials are ready and see if there are no problems before leaving?"
Although Li Chengqian said it very euphemistically, Xu Yunyan already understood Li Chengqian's meaning from between the lines of Li Chengqian's words.
We need to take advantage of these two days to bake the cement. If Xu Yunyan is let go, how will the cement be fired?
Xu Yunyan scratched his head helplessly, "Your Highness, it's not that I don't want to help His Highness, but this cement minister only heard about it from hearsay. It remains to be seen whether it can be fired."
When Xu Yunyan said this, Li Chengqian became anxious.
"Master, you must help Cheng Qian to bake this cement."
"Don't worry, Your Highness. Since cement exists, it can definitely be fired. It's just a matter of proportion."
After Xu Yunyan explained the ratio of fired cement to Li Chengqian in detail, Li Chengqian counted on his fingers and finally figured out how many materials to prepare and how to do it.
Then he looked at Xu Yunyan reluctantly, "Master, I have to prepare all the materials today no matter what, and we will start firing tomorrow morning. Master, you must remember to come to the East Palace early in the morning."
After Li Chengqian warned him like this, Xu Yunyan nodded, but just as he was about to walk out, he turned around and looked at Li Chengqian.
"Your Highness, your son and daughter, why don't you go and see your son and daughter? This is unjustifiable, right? You have to care about your princess, too. You can't let the princess suffer alone without anyone to comfort her, right?"
Xu Yunyan persuaded Li Chengqian here, and Li Chengqian looked at Xu Yunyan and smiled.
"Master, don't worry about this matter. There are plenty of people taking care of the Crown Princess, and I was kicked out even when I went there. I was afraid that I would hurt my child with my carelessness. I am very curious about why my wife is so reasonable and reasonable. That’s how it is…”
Although Li Chengqian did not tell what Xu Yunyan's wife was like, Xu Yunyan understood the meaning behind Li Chengqian's words and sighed helplessly.
Everyone has a life.
At this time, the scene became cold again. Xu Yunyan took this opportunity, hurriedly clasped his fists, saluted and left, happily embarking on the journey home.
"I can finally go home. If I don't go home, the scene you saw on the road may happen. My two ladies will really beat me with sticks."
