Destiny Only Han

Chapter 290 Liu Ying: Laoxiang, you still have a daughter!
Jibei County, Pingyuan County, Dahedukou.

Liu Ying leaned on the railing and saw the ferries full of soldiers, horses, armor, grain and grass on the surging river, passing through the crossings on both sides of the river.

With the arrival of the Marquis Iron Coupon, powerful generals in the Zhao army, such as Yulin general Xu Yu (chì), who stabbed Chen Yu in the back in the "last battle", and the previous proposal to take advantage of Li Shiqi to go to Qi to discuss peace, The friendly general Zhao Jiangye and others who launched the raid immediately threw off Zhang Ao and led the army southward.

Although Zhang Ao personally went to the army to stop him after he got the news, he didn't have enough prestige, and secondly, he didn't have a legitimate excuse, so no matter whether he killed the general who didn't obey his orders or made the other party obey his orders, all It's all impossible.

When the Zhao army split, Yan Wang Zang Tu, who was threatened by Zhang Ao with force, also began to lead the army south.

Well, the reason why Zang Tu was held hostage by Zhang Ao, who was younger than him, is actually very simple. Although Yandi is vast, its population is not large, so it has been repeatedly manipulated by Zhao and Qi since the Spring and Autumn and Warring States Periods.

For this reason, Zang Tu also sent people back to Yandi to take out dozens of carts of gold and silver treasures and special products from the Northland to Liu Ying, trying to use Liu Ying's relationship to make Liu Bang not care about his previous mistakes.

Liu Ying was very satisfied with his act of going on the road, but that was all.

Let you drink the golden cup together, and the white blade will not spare you.

Even if Zang Tu didn't make any mistakes, the place he occupied would involve Liu Ying's future plans, so he shouldn't think about the position of King Yan.

If he is more knowledgeable, he may be able to be a rich and honored prince, and his descendants will enjoy the glory and wealth. If he is not knowledgeable...

Then Liu Ying will allow the self-correction of the historical line.

After killing Xiang Yu, the first prince to be killed was Zang Tu...

Liu Ying turned to look at Han Xin who was standing beside her: "So, can Xiang Yu be destroyed?"

Han Xin chuckled: "Peng Yue is still missing."

Liu Ying collapsed immediately, spreading her hands: "There's nothing I can do about it, but after the Yanzhao army joins up, let's pass by Peng Yue's house for an armed parade! At that time, send two more strategists, and we should be able to persuade Peng Yue .”

Hearing Liu Ying say the word "two strategists", Han Xin's face suddenly darkened.

The so-called two strategists naturally refer to Kuai Che and Wu She who have completed labor reform...

Since the last visit to the Yeyi Gold Mine, Liu Ying met the two of them in private, and they naturally would not let go of this thick leg that was offered to them, so they became Liu Ying's guests.

Han Xin's face was dark because Kuai Che didn't look sideways when he saw him later, as if he didn't see his old master at all...

This is a steal!

But he is not the worst one. After all, Xiang Yu is still looking forward to Wu She's ability to persuade Han Xin to join the Western Chu camp...

Liu Ying watched the ferry for a while, and felt a little bored, so she found a place with slow water flow and began to put in super-large ground cages.

Now that you have come to the Yellow River, you must eat the Yellow River fish!
In later generations, due to overfishing, there are almost no big fish in the Yellow River. A slightly larger Yellow River carp or catfish can easily sell for hundreds of thousands of dollars.

But now, because of the vast land and sparse population, wild animals are everywhere, the ecology of the big river is excellent, and big fish weighing ten catties can be found everywhere.

After a while, the ground cage was put down, and Liu Ying moved a small horse and sat under the tree to wait.

Suddenly, a boundary marker half covered by soil caught his attention.

He dragged the little maza into it and took a closer look. The writing on the boundary marker had basically disappeared, leaving only a few scattered words, indicating that this was once the dividing line between Qi and Zhao.

Liu Ying looked at the terrain where he was now, and found that it was a dilapidated embankment.

The reason why it is said to be broken is because the new embankment is located two miles south of this place.

Although it is not as high as the old embankment, it is strong enough for Shengzai to repair.

Well, the new dam was built by Qin Guo.

In ancient times, the Yellow River took the Huaihe River into the sea, forming a piece of the Subei Plain, but in 2000 BC, it suddenly diverted to North China and flowed into the sea from the later Qilihai Park.

As a result, famous historical events arose.

Dayu controlled the floods.

But before Dayu's water control, the river course had not yet formed, and the mother river frequently diverted its course, turning the entire middle and lower reaches of the Yellow River into a yellow flood zone.

Due to limited productivity, Dayu's method of water control is to block rather than dredge.

That is to use the Taihang Mountains and some dams to create a yellow flood zone controlled by humans.

Anyway, the Central Plains is high in the west and low in the east, so even if the river floods, it will slowly flow eastward into the sea.

Sacrifice a small piece in exchange for the overall benefit.

The land is vast and sparsely populated, that's how willful it is.

But with the passage of time, the population of the Central Plains is slowly increasing, especially after the Spring and Autumn and Warring States periods, when everyone entered the Iron Age as a whole.

Therefore, Qi Jin, Zheng Lu and other countries, in order to protect their land from flooding, chose to raise the embankment on their side.

After a round of engineering competition, the embankment was built higher and higher, and the river bed was raised accordingly.

In [-] BC, that is, the fifth year of King Ding of Zhou, the Yellow River broke through at Suxukou, and the river course went south as a whole, taking the Zhang River into the sea.

So, everyone opened up.

Repairing the dike of the Chicken Feather River, or saving money to develop armaments, destroying the benefits of the neighboring small countries...

But at this time, the amount of sediment in the Yellow River is not large. For example, it is written in "The Book of Songs·Wei Feng·Fatan": "If you cut down the sandalwood, you will dry up the river."The river is clear and rippling.

This kind of Buddhist behavior did not cause too many natural disasters.

That's why the later state of Wei moved the capital to Daliang, which is located on the side of the big river, and built a divide to connect the north and south water systems.

It's a pity that blessings come with misfortunes. During Wang Ben's attack on Wei, he directly dug a gap and flooded the beams. Wei Guo prospered with water and died with water.

Then the world was unified, and there were the old and new embankments that Liu Ying saw at this moment.

At the end of the Spring and Autumn Period, as the temperature and rainfall decreased year by year, the amount of sediment carried by the big river increased year by year. Just as it is said in "Zuo Zhuan Eight Years of Xianggong", when the river is clear, life expectancy is geometric.

That is to say, human life is very short, and it is impossible to wait for the Yellow River to become clear.

This is actually impossible. Unless the loose soil layer on the Loess Plateau can be rammed as a whole, the soil erosion cannot be cured.

The so-called conversion of farmland to forests and grasslands is just to delay soil erosion as much as possible, so as not to accelerate the deterioration.

And the selected vegetation is also particular. After all, the rainfall is so large. If the vegetation needs more water than the rainfall, it will not only fail to fix sand, but will accelerate soil erosion.

Well, sand control is actually a very complicated matter. Just like what the ancients said, there is a danger of muddy water, and there is also a risk of clear water.

The details, written in a paper, can at least pile up a room.

To put it simply, it is like hiding under a tree when it is drizzling. When the rainwater carried by the leaves reaches a certain limit, a gust of wind blows over, which is enough to drench people into a drenched chicken.

Therefore, the best way to control the Yellow River is to build large-scale infrastructure such as Xiaolangdi Reservoir.

But Liu Ying spread her hands, expressing that there was nothing she could do about it.

What he can do is to turn the rammed earth embankment built by Qin into a cement concrete embankment, and then heighten and widen it so that the mother river can flow freely in the spacious channel.

This is a way of imitating future generations.

When the flood season comes, the water level of the Yellow River rises, but because of the constraints of the river course and the old dams, it will not cause harm for a while.

Then, when the water level rose again, the river overflowed the channel, but at this time, because there was a second embankment far away from the river channel and the first embankment, the water would not overflow.

The most important thing is that when the flood rushed out of the river, because of the second dam, it was equivalent to widening the river in disguise.

As a result, the water level naturally drops.

In this way, the flood disaster is reduced to the lightest.

Liu Ying looked at the slightly yellowing river water, and remembered a piece of news that later generations had seen.

The amount of sediment transported by the Yellow River has been far lower than that of the Yangtze River!

In other words, with the rise of the average temperature and the investment of a large amount of funds, the Yellow River will not turn yellow, and the Yangtze River will start to turn yellow...

Therefore, Emperor Wu of the Han Dynasty whose soul passed through Ming Jiajing said well, the sage came out, and Huang Heqing.

Thinking about it, there will be such a phenomenon because the saint has already appeared.

Liu Ying shook her head, putting some thoughts behind her.

On the ground, he continued to draw on the ground according to the world water conservancy map he had seen in Guanzhong before.

Nowadays, the big river has abundant water and is in the golden age of shipping.

Therefore, for the development of the Jiangnan area, we can achieve twice the result with half the effort.

According to The Wealth of Nations, the cost of water transport from London to Edinburgh is 1/40 of that of land transport.

With the gap, the artificial canal that runs through the Yellow River and the Huaihe River, the abundant coal in the central part can easily enter the Huaihe River and the Huaihe River and the water transportation network in the south of the Yangtze River through the Yellow River.

Coal is an abundant and cheap fuel.

And almost all modern industries, such as metallurgy, construction, textile and other industries, have a great demand for coal.

When constraints no longer exist, productivity will be greatly liberated.

And this kind of productivity will in turn force the development of the mining industry.

The steam engine, this cost-effective but expensive drainage tool, has its place.

Then, here comes the age of steam!
Well, in fact, the early steam engines did not need to use rubber as a sealing tool, and hemp silk soaked in grease was sufficient.

Any machinery has losses, as long as the loss of steam is below a certain level, it is completely acceptable.

When Liu Ying was writing and drawing, a three or four-year-old girl staggered to his side, with a crying expression on her face: "Brother, do you know where my home is?"

This is a good question, don't ask it again next time... Liu Ying raised her head, her face full of doubts: "Your name?"

The little girl raised her face, and shyness flashed in her round eyes: "Zang'er..."

ps: Sunday, a little later, you know everything...
