Many people believe that in ancient times, the Yellow River was clear, but in fact, in the late Warring States period, the river has been called the "turbid river", the large-scale collapse of the river, and the change of the celestial phenomena has a direct relationship, in the late Emperor Yao to the Shun Emperor period, and then to the era of Dayu, the three generations of alternation in these decades, it is the whole mountain and sea, from the "cold period" to the "warm period" of a time!

That is to say, the backlog of ice and snow from the era of the ancient Three Emperors is melting year by year, and the rivers of the Western Wilderness are flooding wantonly in the no-man's land, and this warm period will fluctuate during the Shang Dynasty, and finally reach its peak in the early years of the Western Zhou Dynasty.

In addition, two hundred years ago, the emperors fought angrily, the old department of the Yellow Emperor rose in the Western Wilderness, and moved to the east bank of the river, and the Yan Emperor also flourished on the Loess Plateau.

In ancient times, although people also knew the principle of "living in harmony with nature", for example, burning mountains would delineate the range, but this was also because everyone needed wood to make homes, so they could not burn mountains at will, so there was basically no such behavior as "planting trees".

There are many trees, growing every year, but the growth rate has begun to fatigue, the activities and survival needs of the human race exceed the self-resilience of natural trees, and when a field is opened, countless trees will be turned into fireworks and dissipated.

In the smoke of ancient cooking, the trees that have survived since ancient times have been burned one by one.

In addition to human activities, the anger of the earth itself and the erosion of the weather are also the reasons for the devastation of this land, which are the traces left by the years.

In the late Pliocene, the ground of the Loess Plateau was uplifted, and the Yellow River and its tributaries Tao River, Zuli River and Hulu River were cut down with the uplift, and the bedrock ground became a large undulating hilly shape.

Gypsum-containing purple-red clay, sandy clay, sandstone and conglomerate are widely present, these things have poor diagenesis, weaker corrosion resistance, and are prone to gravity erosion under the action of groundwater immersion and lubrication, so large landslides appear one after another.

The loess is high and the primary loess is traced back to the Quaternary Ice Age, when the heavens and the earth were frozen, and countless dust accumulations were superimposed here year by year, and the later loess was the secondary loess, which was accumulated through alluvial and flooding.

In addition, the Yellow River is located in the monsoon region, which makes it particularly prone to water rises during heavy rains, accelerating soil erosion and landslides, leading to natural disasters such as mudslides and catastrophic floods.

The Pliocene epoch was 5.3 million years from this time, and the Quaternary period began at 2.6 million years BC.

The mountains of the western sky, the ice and snow have not yet melted, but the river has been unbearable, to wake up and make chaos, Chongbokun has foreseen, if this winter can not suppress the water, then by the next year, the world will rejuvenate, the mountains of the Western Wilderness, thousands of rivers flow together, the river will be completely turned into an angry dragon, the entire Central Plains will be torn apart!

"My method of blocking water, these embankments built will definitely be able to block the flood, the floods of the previous years, have been tried, and the areas with embankments have been successfully diverted, and the water has not been washed to the banks of the river.....

"Where there is a river embankment, where a city is built, the riverside has not collapsed.... After nine years, this continuous river embankment and this vast city cluster will successfully channel the water into the East China Sea. ”

"The Emperor of Heaven has appointed me to be Sikong, and I will be here to watch the river fall asleep again!"

Chongbokun is facing the people of the Chong clan, the people of the Fanghu clan and the Hanging Yu clan, and is making the final mobilization work for them.

This is a challenge, and the Emperor of Heaven has given them the responsibility of controlling the water, and they must take it up, because thousands of tribes have been plagued by this flood for hundreds of years.

Since the time of Zhuolu, there have been clues, heaven and earth have gradually become active in the past two hundred years, the great floods have continued one after another, the great rivers have collapsed one after another, and the people on both sides of the river have suffered deeply, and this suffering must end this time!

After many experiments, as well as the impact of floods in previous years, although the floods were not very large, the embankment has shown a very strong defense, as long as the river is allowed to follow its original trajectory, there will be no problem!

"Father!"

Behind the people of the Chong clan, there were some young people, another year later, another year older, Wen Ming has reached the age of thirteen, and he is about to enter the age of fourteen, and he has grown taller, although he is still a little childish and has not taken off, but he is already an excellent warrior who can take charge of himself.

"Father, it's not enough to just block the water, it still needs to be channeled, it needs to be drained, and even the lake needs to be dammed, this embankment alone may not be able to resist the big water this time!"

"I've seen it, the water level of the big river is much higher than the previous times!

Kun looked at Wen Ming, he came from the front, and many people from the water control tribe made way for him, at this time, Kun stared at Wen Ming, and said seriously: "You are still young, there are some methods of water control, you have not practiced it yourself." ”

"Gonggong once used to fill hundreds of rivers, dig up mud and sand, build a huge dam, and in the end it was still difficult to reach the flood, the mountains collapsed, and the sound was earth-shattering, terrifying to the gods....."

"After you came back from the south, Heshui told me that they all need to be diverted, but I also told you, diversion, Gonggong has also done this kind of thing before, cutting off the water of the big river, leading it out, and turning it into a piece of lake, but in the end, those lakes were also mobilized by the big water, but instead collapsed and re-injected into the big river, causing a greater disaster!"

"You say that the person in the south who controls the water says that it is necessary to adapt measures to local conditions, and that the big rivers collapse from time to time, and I am building river embankments, isn't it because I am adapting measures to local conditions!

After they came back from the south, they were very happy to tell Chongbo about the new method of water control, but after listening to it, Chongbo gave explanations and responses one by one, and told them some things, it turned out that many methods had been "used" by Gonggong.

In the end, it was of no great use, so Kun found the root of the problem, the more he tossed, the more troublesome it was, but he couldn't leave it alone, so he built this huge river embankment project to minimize human intervention, and wanted to properly guide the water.

"That's different!"

Wen Ming persuaded: "Father, what I saw in the south, their way of driving the flow of water, with you, and the co-workers, they do differently, the words are the same, but the behavior is different, your embankment, I have heard Brother Zai say, if you can't manage it correctly, but increase the embankment, if the river becomes a hanging river on the ground, then the change is dangerous!"

"Some things need to be surveyed and calculated, no matter how strong things are, they are also afraid of the great power of heaven and earth, the fire will roar, the mountain will collapse, and the big water dam will turn into an angry dragon, and Zai Ge will call this power potential energy ....."

Wen Ming's voice became quieter and quieter, and Kun walked over and patted him on the head.

"Maybe he's right, but I think you should trust your father more. ”

"But thinking and practicing, I have been in the south, and I have been for a long time, and you may not know [520 www.biquge520.xyz] that I have looked at the great river for a long time longer than the great river. ”

"Wenming, you don't have to worry, I still have a piece of soil, even if the embankment is partially damaged, it can be repaired immediately. ”

There is a small pouch hanging from the body of the cang, and there is a piece of five-colored soil in it.

Wen Ming looked at this five-colored soil in a daze, and Kun also looked at this piece of soil.

This is what the Dihong clan gave him, and he asked for it from the Dihong clan, the last piece of "resting soil" in the world.
