When the emperor of heaven, the crown prince of Jin, the prime minister Fan Zhen, and the three most powerful people gathered under the tree and listened to Ye Hua explain the method of harnessing water and attacking sand.

"Bianshui originates in the Yellow River, the yellow stream is the most turbid, in the bucket calculation, the sand is the sixth, if to the autumn, then the water is the second. Eight buckets of sand with two liters of water will not be extremely fast, but will stagnate. ”

Ye Hua was not in a hurry, analyzing the causes of the siltation of Bianshui.

Guo Wei and Chai Rong are not good at this, they just listen to it, but after all, Fan Zhen has presided over the repair of the river for more than a year, and he knows it in his heart, what Ye Hua said is indeed very reasonable.

"Champion Hou, the reason is good, it's easy to silt, shouldn't you dredge the river?"

"Don't be busy!"

Ye Hua continued: "The moisture is slow, the sand stops, the sand stops, the sand stops, the river is full, and the water of the size has a sand surface, and it is high to see it. Hydration is fierce, fierce is sand brush, sand brush is deep, and the water of the zhang has the bottom of the river, and it is humble to see it. ”

In a word, the water is fierce, the sediment is washed away, the water is slow, and the sediment will be silted!

As soon as these words came out, Fan Zhen was shocked and almost screamed out.

In order to dredge the river, he just wanted to dig out the river sand and let the water flow smoothly. The more sediment accumulates, the more people will be mobilized, but the manpower is always limited, how can it be compared with the surging river.

"Does Champion Hou mean to use the power of the river to wash away the silt and sand?"

"That's right! Build an embankment to restrain the water, and use the water to attack the sand, and if the water does not overflow on both sides, it will go straight to the bottom of the river. A certain reason, an inevitable trend, the reason why this combination is more and more divided. ”

Ye Hua said this truth, not his first creation, this is the Ming Dynasty river control expert Pan Jitao's point of view, this invention of the method of water and sand, hundreds of years later, is still the guiding principle for the management of the Yellow River. The water and sand diversion often carried out in later generations is an upgraded version of Pan Ji's method of taming water and attacking sand.

Ye Hua has read the article about Pan Jitao, and admires this rare water conservancy master very much, and Ye Hua has written down his water control methods.

Now that he is talking about Fan Qian, this Fan Xianggong is dumbfounded, he held his head and thought about it for a long time, and then said with a bitter face: "Champion Hou, why didn't you tell the old man earlier!" ”

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

"I, how did I know you could cure the water!" Fan Zhen was annoyed.

The two blamed each other.

Guo Wei coughed twice, "Let's get down to business, what to do?" Is Champion Hou's approach feasible? ”

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

"Why?" Guo Wei asked.

"Your Majesty, the day of the flood season is not far away, at most half a month, and it is too late to build an embankment to contain the water now." Fan Zhen can't regret it, if he had asked Ye Hua a few days earlier and asked him what he thinks, maybe he wouldn't have to work so hard, and it would be too late to regret it!

Old Fan beat his chest, Guo Wei and Chai Rong also sighed.

Ye Hua's eyes rolled, and he said in a low voice: "That, Fan Xianggong, it may not be too late to build an embankment at this time!" ”

"Not too late?" Fan Zhen was shocked and asked, "Why is it not too late?" ”

"Well, I have a thing in my hand, called cement, which is used to build a dam to keep the river from attacking...... From now on, mobilize craftsmen and people, within 10 days, repair 60 miles of embankment, there should be no problem! ”

"Champion Hou, you're not lying, are you!" Fan Zhen's eyes lit up, and he immediately said: "Your Majesty, the old minister thinks that the embankment should be built immediately!" ”

Guo Wei has no opinion, anyway, whether it is repairing the river or cement, he doesn't know anything, and what Guo Wei is most interested in at the moment is what else this kid Ye Hua will have!

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

"Fan Xianggong, I can't wait."

"Why?" Fan Zhen's eyes widened.

"It takes time to make cement, so you'd better rest now, and the people, let the big guy rest for a day, recover their strength, and then go all out to work, and each person will be given 10 copper coins a day." Ye Hua suggested.

Guo Wei thought for a while, nodded and said, "Just do what Ye Hua wants, Fan Xianggong, you should also pay attention to your body, and you must not be exhausted." ”

Fan Zhen said guiltily: "The incompetence of the old minister has made His Majesty worried." ”

……

Fan Zhen barely slept for a night, and as soon as it was dawn, he arrived at Ye Hua's workshop.

Ye Hua's movements were not slow, the carriage and horses were ready, and the cement was loaded in wooden barrels, and the barrel mouth was tightly sealed and transported outside. Fan Zhen was curious, "Champion Hou, what is this?" Is there really such a god? ”

Ye Hua smiled, "Fan Xianggong, this thing is an ancient recipe that I stumbled upon, and it is very difficult to refine. It is said that this is what the female snail used to make up for the sky back then, you say it's not powerful! ”

Fan Zhen snorted, he wouldn't believe Ye Hua's nonsense.

"Whether it's good or not, you don't know until you've used it!"

Ye Hua said, took out an instruction manual, stuffed it to Fan Qian, and then thought about it, it would be more reassuring to send a few craftsmen over. However, before leaving, Ye Hua repeatedly told him not to talk too much, if anyone asks about cement, he only says that he doesn't know.

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

"To tell you the truth, are you holding back the bad and wanting to take the worthless cement and make a lot of money?"

Ye Hua Zhengse said: "Whether it is worth it depends on the use, if you can dredge the water, do you dare to say that the cement is not worth much?" ”

"You just use some slag, limestone, clay, how can it be worth it?" Chen Shi was honest and explained the old story.

"You, don't want to get rich in this life."

Ye Hua gritted his teeth, what a stubborn stone! He can only stay in the workshop for himself and supervise the workers to build armor and Mo knives, after all, after ten days, he will have to pay to the Privy Council, which is also a big business, and he can't make mistakes.

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

Although the method of harnessing water and attacking sand is very good, there is a premise, that is, the river embankment should be strong.

If there is a problem with the river embankment, not only will it not be able to contain water, but it will destroy the embankment and cause heavy losses. During the construction, Pan Jitao demanded that "the soil must be real and not mixed with floating sand, high and thick without sparing the cost of residence", "one by one cone probing the embankment" and other methods to ensure the quality of the project and be able to withstand the erosion of the water.

Time is really too little, Ye Hua has been running around day after day, building different river embankments according to the topography of each section, including remote embankment, wisp embankment, grid embankment, Taihang embankment, earth dam and so on.

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

But even so, it was an eye-opener for Fan Qian.

Mix the cement and sand and gravel in the proportion, pour it on the embankment, and after about three days, it will become as strong as a stone, and when you hit it with a hammer, there will be only a faint white spot.

He even felt that what Ye Hua said made sense, this thing can make up for the sky, and it is definitely a treasure only owned by immortals!

In less than ten days, the craftsmen played with their lives and repaired nearly 70 miles of river embankment, and now everything is ready, just waiting for the river. Fan Zhen paid his wages in advance, dismissed all the people, and asked them to go home and reunite as soon as possible.

The old man washed up, changed into clean clothes, and climbed the embankment, where the muddy water was now. On the side of his river embankment, there are iron dragon claws used to clean up sediment and mud trucks...... Looking at those things, Fan Zhen shook his head and smiled bitterly, he was so old, he only knew how to use manpower, and he didn't know how to use the power of nature, it was really embarrassing!

He was sighing, Ye Hua actually came.

"Fan Xianggong, you don't think about it, if you don't succeed, jump into the turbidity current and commit suicide to apologize!"

is in a good mood, when Ye Hua said this, the old man's beard was puffed up.

"The old man fasted and bathed and prayed to heaven...... If the Bianshui can be successful, this method can be used on the Yellow River, and if the Yellow River is controlled, the flood of the millennium will be eliminated. The saint is out, the Yellow River is clear! The old man is looking forward to reviving the rule of three generations! ”

Ye Huacai didn't believe in the rule of three generations, and he said in a matter-of-fact manner: "I remind Fan Xianggong that everything has a first time, and I dare not guarantee whether I can hold it up." ”

"Then you dare to come?"

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

Only then did Fan Zhen notice that Ye Hua really came with many people. Lao Fan took a deep breath, "Being an official in the same dynasty is like taking a boat, the old man is advancing and retreating with you, and he wants to die together!" The embankment will be handed over to you first. After this person finished speaking, he walked away, with a sigh of air in his mouth, and actually went to rest, is this his solidarity?

Ye Hua was really speechless......
