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 praising: "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 a situation of 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, not only the flood disaster problem of the Jinma River can be solved, but also the drought problem of the Sichuan-Sichuan Plain!"
Dujiangyan is mainly composed of three parts: Baopingkou, Feishayan and Shuifuzui.
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?"
Wei Datong asked quickly.
"Can't find it." Jin Feng shook his head.
They are not from the same world, so where can I find them?
Jin Feng visited Dujiangyan in his previous life. The tour guide said that Dujiangyan is the earliest water conservancy project in the world. It has been in use for more than two thousand years since the Qin Dynasty and is known as the "Treasure of Zhenchuan".
However, Jin Feng thought that the tour guide was deliberately bragging and did not believe that the projects built during the Qin Dynasty could last for more than two thousand years.
Maybe nerds who study science like to be more serious. After returning home, Jin Feng specifically looked up the detailed information about Dujiangyan.
You won’t know if you don’t check, but you’ll be shocked if you check.
The tour guide wasn't bragging, maybe even being modest.
For the Sichuan Plain to become the "Land of Abundance", Dujiangyan is indispensable.
Jin Feng was truly amazed by the wisdom of Li Bing and his son, as well as the ancient working people.
If Li Bing and his son had not spent eight years with countless people to build Dujiangyan, Jin Feng would not have thought of a way to drill through Yulei Mountain.
Telling Li Bing's name to Wei Datong also wanted his contribution to be passed down in this world.
This is the most basic respect for the ancestors.
"Can't find it? What a pity."
Wei Datong shook his head with regret.
"Master Wei, you are most familiar with the Jinma River. Do you think the method I just mentioned is feasible?" Jin Feng asked.
Wei Datong did not rush to answer this time, but stared at the sand table and map, thinking carefully.
After a long while, he raised his head and said: "Sir, this is a huge project, and the manpower and material resources it requires are unimaginable..."
The Ninth Princess interrupted Wei Datong: "You just answer sir whether it is feasible. As for money and food, you don't have to worry about it. I will take care of it myself!"
"Replying to Your Highness, I think what you said is quite reasonable. However, this matter is very important and requires countless people to be mobilized. I need to conduct on-site investigation before I dare to confirm it."
Wei Datong bowed and answered.
Jin Feng, Ninth Princess, and Qing Xinyao looked at each other and nodded slightly at the same time.
In fact, this was also a test for Wei Datong by the three of them.
Jin Feng's plan not only required the construction of Dujiangyan, but also the digging of numerous ditches throughout Sichuan and Sichuan for flood discharge and diversion for irrigation.
Such a huge project requires a huge amount of manpower and material resources. If Wei Datong agreed directly without thinking, Jin Feng would really not dare to use him.
"Master Wei is right to be worried," Jin Feng nodded and said, "Well, tomorrow morning, I will take Master Wei to inspect the Jinma River."
"Sir, inspecting rivers and mountains is too hard and takes a lot of time. Please don't follow me. Wei can just take someone with him."
Wei Datong waved his hand and said.
"With me following you, Mr. Wei won't have to work so hard or spend too much time." Jin Feng said with a smile.
"Sir, this matter is of great importance and cannot be trivial." Wei Datong shook his head repeatedly.
"Master Wei, I naturally know that this matter is not a trivial matter, and I will never do it."
"Sir, do you have any tips?"
Wei Datong finally noticed something was wrong.
Based on his understanding of Jin Feng, he would not have spoken like this unless he was completely sure.
"Your Excellency will know tomorrow morning."
Jin Feng started to play mysterious.
"Then Wei will wait and see!"
Wei Datong saw that Jin Feng was unwilling to say more and did not force him. He lowered his head and looked at the sand table again.
Wei Datong could suppress the curiosity in his heart, but Qing Mulan could not, and asked curiously:
"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.
