The emperor of the dynasty, the crown prince of Jin, and the prime minister Fan Zhi, and the three most powerful people surrounded the tree and listened to Ye Hua explaining the method of tying water to attack sand.

"The Bian River originates from the Yellow River, and the yellow stream is the most turbid. Use Dou to calculate it, and sand is the sixth. If it reaches the autumn, then water will be the two. If two liters of water carry the eight Dou sand, it will cause stagnation if it is not very fast."

Ye Hua analyzed the causes of the siltration of the Bian River.

Guo Wei and Chai Rong are not good at this, they just listen to it. But Fan Zhi has been in charge of Xiuhe for more than a year and knows what Ye Hua said is indeed very reasonable.

"Champion Hou, the principle is good and easy to accumulate. Should the river be dredged if it is not right?"

"Don't be busy!"

Ye Hua continued: "Water is slow, the momentum is slow, the sand stops, and the river stops, and the water of the size has a sand surface, so you can only see it high. When the water is combined, the momentum is strong, and when the sand is strong, the river is deep. When the water is short, the water will all have a bottom of the river, so you can only see it low."

In a word, the water is strong, the mud and sand will be washed away, and the water is slow, so that the mud and sand will accumulate!

As soon as this said, Fan Zhi was shocked and almost called out.

In order to clear the river channel, he just wanted to dig out river sand and make the water flow smoothly. The more silt, the more civilians mobilized, but the manpower was always limited, so how could it be compared with the surging river water?

"What is the Champion Hou meant to use the power of the river to wash away the silted mud and sand?"

"That's right! Build a dike to bind water and use water to attack sand. If the water does not overflow on both sides, it will definitely brush to the bottom of the river. A certain principle and a certain momentum, this combination is more and more divided."

The reason Ye Hua said was not his first idea. This is the view of Pan Jixun, an expert in river control in the Ming Dynasty. This method of binding water and attacking sand invaded by the method of binding water and attacking sand hundreds of years later was still the guiding principle for controlling the Yellow River. The water and sand diversion that was often carried out in later generations is an upgraded version of Pan Jixun's method of binding water and attacking sand.

Ye Hua has read articles about Pan Jixun and admires this rare water conservancy. Ye Hua has recorded his water treatment methods.

Now that he told Fan Zhi, the husband Fan was stunned. He held his head and thought for a long time, then he said with a bitter face: "Champion Hou, why didn't you tell me earlier!"

Ye Hua said helplessly: "I have been busy all the time, and you didn't ask me!"

"Me, how did I know you can control water!" Fan Zhi was very upset.

These two people blame each other.

Guo Wei coughed twice, "Let's talk about serious business, what should I do? Is the method of champion Hou feasible?"

Fan Zhi smiled bitterly and said, "Champion Hou's method should be feasible, but this year, I'm afraid it won't work?"

"Why?" Guo Wei asked.

"Your Majesty, it's not too far from the flood season. At most half a month, it's too late to build a dike and tie up water." Fan Zhi regretted it. If he had asked Ye Hua earlier and asked his opinion, he might not have to work so hard, it would be too late to regret it!

Old Van beat his feet and his chest, while Guo Wei and Chai Rong sighed.

Ye Hua's eyes rolled and he whispered: "That, Mr. Fan, it may not be too late to build the dike at this time!"

"It's not too late?" Fan Zhi asked in surprise: "How could it be not too late?"

"It's like that. I have something on my hand, called cement, used to build dams and can withstand river water invasion... From now on, we will start craftsmen and civilians and build 60-mile river embankments within 10 days, and there should be no problem!"

"Champion Hou, you didn't tell lies!" Fan Zhi's eyes shone and he immediately said, "Your Majesty, the old minister thinks he should build a dike immediately!"

Guo Wei had no objection. He knew nothing about it, whether it was Xiuhe or Cement. What Guo Wei was most interested in now is what else did Ye Hua know about it!

He is really his lucky star, and he is constantly surprised!

"Goodbye Fan, I can't be anxious."

"Why?" Fan Zhi widened his eyes.

"Cement production takes time, so you'd better take a break now. There are also civil servants, let everyone rest for a day, recover their strength, and then work hard, each person will be given 10 copper coins a day." Ye Hua suggested.

Guo Wei thought for a while and nodded, "Just do as Ye Hua wants, Mr. Fan, you should also pay attention to your health and must not be exhausted."

Fan Zhi said guiltily: "The old minister is incompetent, and His Majesty is worried."

...

Fan Zhi could sleep for a night and just dawned, he arrived at Ye Hua's workshop.

Ye Hua was not slow, and the carriage was ready, and he packed cement with wooden barrels, sealed the mouth of the barrel tightly, and transported it outside. Fan Zhi was very curious, "Champion Hou, what is this? Is it really that magic?"

Ye Hua smiled, "Mr. Fan, this thing is an ancient recipe I discovered by chance. It is very difficult to refine. It is said that this was the one used by Nvwa Empress to repair the sky back then. Do you think it is powerful or not!"

Fan Zhi snorted, he would not believe Ye Hua’s nonsense.

"Okay or not, you have to know if you have used it!"

Ye Hua said, took out a manual for use and stuffed it to Fan Zhi. Then he thought, he would rather send a few craftsmen over there. However, before leaving, Ye Hua repeatedly reminded him not to talk too much. If anyone asks about cement, he will only say he doesn't know.

When there was no one, Chen Shi pulled Ye Hua aside.

"To be honest, are you trying to make a big deal of money by trying to get valuable cement?"

Ye Hua said seriously: "Whether it is worth it depends on the purpose. If you can clear the Bian River, how dare you say cement is not worth it?"

"Just use some slag, limestone, and clay, how can it be valuable?" Chen Shi honestly explained his true feelings.

"You, you won't be able to get rich in your entire life."

Ye Hua gritted his teeth, it was such a stubborn stone! He could only let him stay in the workshop for himself and supervise the workers to build armor and modao. After all, he had to report to the Privy Council ten days later. This is also a big business and no mistakes can be made.

Ye Hua personally rushed to the Bian River to supervise the construction of the river embankment.

Although the method of binding water to attack sand is very good, there is a prerequisite, that is, the river embankment should be strong.

If there is a problem with the river embankment, not only will the water be unable to be bound, but the embankment will be destroyed and people will be killed and the losses will be heavy. During construction, Pan Jixun asked "real soil should be real and not mixed with floating sand, high and thick but not to worry about living expenses", "exploring the earth embankment one by one" and other methods to ensure the quality of the project and to withstand the erosion of heavy water.

There is really too little time. Ye Hua has been working for days and built different river embankments according to the terrain of each section, including Yaodi, Ludi, Gedi, Taihangdi, Earth Dam, etc.

With the current cement production, it is only enough to be used in key places, and it is impossible to build a real cement dam.

But even so, it opened Fan Zhi's eyes.

Mix the cement and gravel placement ratios and pour it on the embankment. After about three days, it will become as strong as the stone. When you hit it with a hammer, there will be only a faint white dot.

He even thought what Ye Hua said made sense. This thing can replenish the sky and is definitely a treasure that only gods have!

In less than ten days, the craftsmen had their lives and overhauled the river bank of nearly 70 miles. Now everything is ready, just waiting for the river water. Fan Zhi paid his wages in advance, dismissed all the civilians and asked them to go home and reunite quickly.

The old man washed up specially, changed into clean clothes, climbed the embankment, and now there was the turbid Bian River. There were iron dragon claws used to clean up mud and sand, and mud trucks... Looking at those things, Fan Zhi shook his head and smiled bitterly. It was a pity that he knew how to use manpower and not the power of nature!

He was feeling that Ye Hua had come too.

"Mr. Fan, you are not thinking that if you fail, jump into the turbid current and commit suicide and apologize!"

He was in a good mood, and after Ye Hua said this, the old man's beard was pouted.

"I fast and bathe, pray to heaven... If the Bian River can be successful, this method can be used on the Yellow River. If the Yellow River is controlled, it will eliminate the flooding of thousands of years. The saints come out and the Yellow River is clear! I am looking forward to revitalizing the three generations of governance!"

Ye Huacai didn't believe in the three generations of rule. He said seriously: "I remind Mr. Fan that there is a first time in everything, and I can't guarantee whether I can hold on."

"Then you dare to come?"

"I borrowed troops from His Majesty and came to guard the river embankment in advance."

Fan Zhi then noticed that Ye Hua was indeed brought with many people. Lao Fan took a deep breath, "Being an official in the same dynasty is like a boat. I will advance and retreat with you, and I will be together with you! I will leave the river bank first." After saying that, the man walked away, breathed his breath, and actually went to rest. Is this his work together?
