Da Qin: The First Emperor was reborn and made me the crown prince at the beginning

Chapter 360

In this way, Yingchen invited Wang Jing into his Zhangtai Palace.

Not only that, Yingchen also recruited the heads of the three provinces and nine departments together.

Within a while, Xiao He and the others came to Zhangtai Palace.

At this time, Yingchen was discussing with Wang Jing how to control the Yellow River.

After Xiao He and the others came, Ying Chen directly introduced Wang Jing to them.

"This is Wang Jing, and he is the immortal material I specially recruited to govern the Yellow River!"

After listening to Yingchen's introduction, the ministers present were suddenly shocked.

It turns out that this person is the one who makes Yingchen miss so much these days.

At the same time, they finally understood why Yingchen attached so much importance to Wang Jing.

For the Yellow River, which has often burst in the past few years, not only the crown prince of the empire Yingchen, but also the current emperor is worried.

Even the ministers in the court, who knew everything about the place and all the things about the Yellow River, were worried at the same time.

After all, on both sides of the Yellow River, there are tens of millions of people living.

Not only that, but the Yellow River basin is now also an important area for the economy and production of Daqin.

If the Yellow River can be effectively controlled, it will be a great thing of great merit for the tens of millions of people along the Yellow River and for the entire Great Qin!

At this moment, Ying Chen continued: "I mentioned a question with Mr. Wang Jing just now, which made me suddenly have an idea. "

"The problem is, if you want to control the Yellow River, you need to understand why there is so much sediment in the Yellow River!"

As soon as these words came out, everyone present was stunned.

This question has some implications for going straight to the root.

It's a pity, although these people can be said to be the smartest people in Great Qin.

Especially there is such a virtuous appearance as Xiao He.

However, there is a specialization in the so-called art industry.

Let Xiao He and the others think about this somewhat professional thing, but it is really a little difficult for them.

And Wang Jing, as a character who came to this time and space with the memories of his previous life, has some understanding of this issue under the prompting of Yingchen.

Wang Jing immediately spoke: "But where there is a river, there must be a source!" "

"According to Wechen's experience, the sediment in the Yellow River seems to be segmented."

"In the Longxi area, there seems to be less sediment in the Yellow River."

"And the more you go to the middle and lower reaches of the Yellow River, it seems that the more sediment content in the Yellow River water will be."

"This situation must be due to a situation in the upper reaches of the Yellow River, which has caused more sediment in the middle and lower reaches of the Yellow River."

Hearing Wang Jing's words, Yingchen couldn't help but nod again and again.

In fact, this problem is also thanks to Yingchen's previous life, where he studied liberal arts.

Geography in the liberal arts explicitly mentions this issue.

At that time, Yingchen's geography teacher had popularized the concept of "soil erosion" with him.

But Yingchen didn't listen carefully at that time, and after Yingchen crossed over to Daqin in this time and space, Yingchen focused more on other aspects.

And as time went by, this knowledge point made Yingchen a little unable to remember.

And now, after a discussion with Wang Jing, a famous river control expert, Yingchen finally sounded the knowledge points that the geography teacher once said.

In this regard, Yingchen said: "Actually, there is a concept in this - soil erosion!" "

"What is soil erosion, in fact, if we observe this phenomenon carefully, we will find something."

"If our current hits the ground, it's going to take some dirt with us."

"And if we replace the ordinary flow of water with a river, or even a big river like the Yellow River, how much soil will it take with him wherever he passes."

"This phenomenon is soil erosion."

After listening to Yingchen's explanation, not only the Manchu Dynasty civil and military, but even Wang Jing, an expert in river governance on the side, couldn't help but have a sense of sudden enlightenment!

At this moment, the civil and military forces of the Manchu Dynasty didn't know what to say about Yingchen.

It is said that long before that, they already knew that Yingchen was proficient in agricultural planting, Mojia organs, soldiers' killing, the way of the emperor, etc.

But I didn't expect that Yingchen now even knew such a professional thing as governing the river.

This is really not enough to describe the hexagonal warrior.

And in fact, there was a kind of joke in the previous life. (Read violent novels, just go to Feilu Fiction Network!) ）

When is a person at his most knowledgeable?

After the college entrance examination!

I know astronomy and geography, and I know the history of language and mathematics.

And if you are a little genius, even the knowledge of science can surpass that of the ancients before the seventeenth century.

After all, before Newton, no one knew what gravity was.

Before Gauss and other mathematicians, even the unary quadratic equation was something that only the top talents in mathematics could master.

And if a person travels to the Tang Dynasty, then with the poems he has memorized, it is enough to be a great writer who will go down in history.

And with a little knowledge of chemistry, you can be rich.

It can only be said that modern people who have come out of the explosion of knowledge know too much compared to the ancients.

Just like now, don't look at the theory of Yingchen as easy as it sounds.

But this is the knowledge that countless geographers have been able to obtain after much research.

It can only be said that the difference in the times is simply greater than heaven and earth.

To a certain extent, now human beings can create weapons that can easily destroy a city, can communicate thousands of miles away, and even control the power of thunder, in the eyes of the ancients, it is not a means like a god!

Therefore, now Yingchen stands on the shoulders of countless predecessors and directly points out the problem.

Naturally, there is a sense of being commanding right.

Immediately afterwards, Yingchen said: "Of course, the problem of soil erosion is actually present in every river, but why is it that the Yellow River has the most cement sand?" "

"That's because the northern part of Guanzhong, Shuofang and Yunzhong counties, through which the Yellow River passes, already have less rain, and the activities of agriculture and animal husbandry are too developed."

"You know, if you want to solve the problem of soil erosion, vegetation cover is the most critical issue."

"A tree can hold a two-metre area of soil, while a forest or a grassland can hold a large area of land."

"And if the vegetation is completely destroyed and becomes a sand dune, the soil will enter the Yellow River, for example, and bring endless sediment downstream."

"And the more sediment and the higher the riverbed, the greater the probability of the Yellow River bursting, for example!"
