When he was at the Jinma River, Jin Feng discovered that Wei Datong was very knowledgeable about water conservancy and was very familiar with the waters around the Jinma River.
With the help of Wei Datong, Jin Feng was able to successfully find a suitable place and divert water to flood Danzhu's cavalry.
Therefore, after making the decision to build water conservancy projects, Jin Feng immediately recommended Wei Datong to the Ninth Princess.
Facts have proved that Jin Feng's decision was correct.
Wei Datong just took one look at the sand table and immediately discovered the mystery, which shows that his basic skills are very solid.
"I made this sandbox randomly with mud, which made Mr. Wei laugh."
Jin Feng waved his hand.
Model making is also an essential skill for mechanical majors. When Jin Feng was in school, he did this part-time several times.
Although the water conservancy sand table produced is not very standard, it captures the geographical characteristics of the Dujiangyan area.
"Sir, you are so humble. This sand table is so well made!"
Wei Datong seemed to have completely forgotten the existence of the Ninth Princess and Qing Xinyao. He walked to the sand table and observed carefully while admiring: "There are mountains, rivers, everything that should be there. It is simply a shrunken Jinma River... Hey, this
What is it?"
Wei Datong pointed to a place and asked: "There is no hole here, and it is different here..."
The first place he pointed to was the location of the Baopingkou of Dujiangyan.
Baopingkou did not exist before. It was built by Li Jiang and his sons who led the people to dig through Yulei Mountain.
There would be no Baopingkou in this world without Li Bing.
But on the sand table, Jin Feng left a hole in Yulei Mountain.
What Wei Datong later pointed out was also the change made by Jin Feng based on Dujiangyan.
"The reason why the Jinma River is often flooded is because Yulei Mountain blocks the eastward flow of the river, and the river channel in the west is narrow, so once the water level rises, there will be drought in the east and floods in the west."
Jin Feng took out a map and pointed to the location of Yulei Mountain: "If we dig a hole in Yulei Mountain, and then let the people build canals to divert the river water into Jiang'an River, Zouma River, and Baitiao River."
The water systems of these three rivers are complex. The water of the Minjiang River can irrigate Mianyang, Shehong, Jianyang, Ziyang, Renshou, Qingshen and other places, and can irrigate more than 10 million acres of fields in most of the Sichuan-Sichuan Plain!
In this way, we can not only solve the flood disaster problem in the Jinma River, but also solve the drought problem in the Sichuan-Sichuan Plain!"
Dujiangyan is mainly composed of three parts: Baopingkou, Feishayan and Shuishuiyuzui.
After explaining Baopingkou, Jin Feng explained Feishayan and Shuishuiyuzui.
Wei Datong's eyes widened, completely frightened by Jin Feng's words.
He thought that Jin Feng wanted to control the Jinma River by taking advantage of the lack of rain in spring to clean up and widen the river channel. Who knew that Jin Feng actually wanted to dig through Yulei Mountain!
Even if he broke his head, he couldn't think of a way to dig through Yulei Mountain and divert the water of the river.
"My God! Sir, how did you come up with this idea?"
Wei Datong's eyes were full of shock.
The same is true for the brothers Qing Xinyao and Qing Mulan who heard about Jin Feng's plan for the first time.
The corners of the Ninth Princess's mouth raised slightly, and she also recalled the expression on her face when Jin Feng discussed it with her for the first time. I'm afraid it was the same as Qing Mulan's, right?
"I happened to hear an expert named Li Bing talk about it."
Jin Feng once again threw his hat to the so-called "master".
"Li Bing? Sir, can you still find this expert?"
"Sir, what method are you going to use? Can you take me with you tomorrow morning?"
[The author has something to say]
I checked the information all afternoon and described the history, layout, and construction process of Dujiangyan in detail. I wrote more than two chapters. After I finished writing, I felt that it was unnecessary and people probably didn’t like to read it, so I revised it again and wrote a 5,000-word article.
The content has been compressed to 2,000 words...I'll post it first for everyone to take a look at, then continue writing.
