Daming: I just wanted to hold on, but you forced me to make a move

“Let’s not watch it, you tell us!”

“Good!”

Zhu Yunxi took out a picture from his pocket, “This is the water conservancy map of the world that Kuanxiang gave me, which was drawn by Quanxiang’s father, although there are some differences in the general, but it can barely be used.” ”

Really! Zhu Yunjiang was angry for a while, and everyone helped him.

“As for what the second brother said.”

Of course, I know that Zhang Qiu broke the embankment of a section of the canal to the Yongding River, but this is only a superficial phenomenon, if you just dig it through, it is a quack!” ’

“Headache heals head and foot pain, but treats the symptoms but not the root cause.”

‘Therefore, I think it is necessary to be more stable, and after checking the Wang Jingzhi Water and Yundao Yuanshui Scriptures, I found that the most fundamental place in the canal silting lies in ~’

“Yellow River!”

“The water of the canal uses the water of the Yellow River, because of the soil erosion upstream, the Yellow River accumulates sediment, causing the riverbed to become higher and higher, and the same is true for the canal!”

“Therefore, the key to managing the canal is to control the Yellow River!”

Zhu Yuanzhang felt that his scalp was a little numb, and this pattern suddenly rose.

And Zhu Yunjiang has long been stupid … Doesn’t that mean canals? How did it get to the Yellow River?

“At the end of the Northern Song Dynasty, the Jingkang Dynasty changed, and the Jin army dug the Yellow River embankment and flooded Kaifeng City, causing the Yellow River to be diverted, and it has not been stable for hundreds of years.”

“Many people say that the Yellow River can be managed by widening its course, but after studying with Kuang Xiang, I felt that it was best to do the opposite.”

“The river needs to be reduced with cement so that the water flow is faster.”

“The sediment in the river embankment will also be naturally washed away, this is the method of bunching water to attack the sand!”

Zhu Yuanzhang looked at Zhu Yunxi stunned, originally a very simple test question, but let him play flowers.

“Bundle water to attack the sand?”

Quang Xiang touched his head, “This strategy was mentioned by His Highness, I just participated in the discussion.” ”

Qin Dadenshi praised, “Your Majesty, this strategy is absolutely feasible. ”

“Have you already used it?” Zhu Yuanzhang asked casually.

“Before the Xin’an River broke its embankment, Wei Chen was distressed, at that time, His Royal Highness the Third Emperor Sun proposed to bind water to attack the sand, and after Wei Chen used it, Xin’an River never had an accident again!”

“This policy is the foundation of water control, and it can become a reference for all generations.”

Huang Zicheng retorted: “Is it such an exaggeration? The Yellow River has a large flow rate, but if the river channel is reduced, what if the embankment breaks? ”

“That’s a catastrophe!”

Zhu Yunxi nodded: “I also thought of this, so I didn’t tell Grandpa Huang about the method of bundling water and attacking sand at that time, and after the cement was successfully developed, the grasp of dealing with the Yellow River increased a lot!” ”

Zhu Yuanzhang looked at him mockingly: “Then if we hadn’t raised this question, wouldn’t you have said it?” ”

“After all, the cement is not strong, I also know that there is a thing called reinforced concrete, this thing is powerful!”

“Enough to withstand thousands of feet of weight!”

I’m going to get the reinforced concrete out.” ’

Zhu Yuanzhang: …

“What is the success rate if you use cement alone?”

‘Seventy percent! ’

“I also thought about it, I also need to add a second layer of remote embankment and a third layer of moon embankment outside, in case the Yellow River really bursts, the remote embankment and the moon embankment can slow down the water and turn the mudflats into fertile fields by the way.”

“The best of both worlds. So sure that there are nine things! ”

Zhu Yuanzhang silently added one percent in his heart: “Enough!” ”

“Bundles of water to attack the sand… All right! ”

“Our big Ministry of Engineering is actually not as comprehensive as Xi’er you think alone!”

Zhu Yunxi interrupted Zhu Yuanzhang’s words, “I thought about it later, and I felt that this was not very comprehensive. ”

“The northern section of the canal uses the water of the Yellow River, but the southern section uses the water of the Huai River.”

‘What is the use of using bunches of water to attack sand and control the Yellow River? If the Huai River is broken, the canal will be broken! Therefore, it is necessary to control the Huai River! ’

Zhu Yuanzhang: …

I just wanted you to make a simple canal, why are you playing so advanced?

Zhu Yunjiang felt the dimensionality reduction blow from others.

The world is full of malice.

“How to govern the Huai River?”

“Easy too! After Jingkang, the Yellow River seized Huai into the sea, and the Yellow River flowed fast, so it could always break the embankment of the Huai River! We need to reinforce the Huaihe embankment with cement! ”

Zhu Yuanzhang learned smartly: “Is there anything else?” ”

“And.”

We know….

“Does Grandpa Huang know about Hongze Lake?”

“Of course, when we went to attack Zhang Shicheng a few years ago, we passed by Hongze Lake!”

“The source of water for the Huai River is Hongze Lake, but Hongze Lake has recently been surrounded by farmland, resulting in a continuous lowering of the water level. Therefore, Hongze Lake should be returned to the lake, and the water level of Hongze Lake should be raised by 12 feet, and the speed of the Huai River will be greater than the speed of the Yellow River, so that the Huai River embankment made of cement will be safe. ”

Twelve feet tall? You even figured this out?

“The north and south of the canal are solved, just use the usual water gate to divert water normally, according to my estimates, within fifty years, there will be no problems!”

“Fifty years?” Zhu Yuanzhang was really stunned this time.

Quang Xiang interjected: “Weichen thinks that there will be no problems within a hundred years, His Royal Highness the Emperor Sun must say that he is more stable, and estimate it for fifty years.” ”

“Shut up!” Zhu Yunxi scolded.

“Obey.”

Zhu Yuanzhang: …

For a while, the pattern was high, and a water conservancy map framed the entire Ming Dynasty.

And the other will be cautious and maddening.

Which is the real Xi’er?

Zhu Yuanzhang was confused….

(Is it stable enough?) ）

(Ming’er is going to buy clothes, it is estimated that the update will be less)

(Years ago, there were too many things.) ）
