Li Jie stood on the embankment and tried his best to look into the distance, only to see that the long river under his feet was like a yellow dragon, rolling down from west to east, carrying countless mud, sand, soil and stones along the way, and the thick embankment seemed to be trembling slightly under the impact of the river, as if the yellow dragon might come out at any time.

"The water of the Yellow River comes up from the sky, rushes into the sea and never returns!" Zhu Biao couldn't help but whisper at this time, this is the first time he has seen the Yellow River, although the Yangtze River is no worse than the Yellow River, but the Yellow River is the mother river of China after all, and it occupies an important position in the hearts of all the descendants of Yan and Huang.

"Although the Yellow River is magnificent, it has become an above-ground river, and only relies on the river embankment to bind the river water, in case the river embankment bursts one day, it will be a catastrophe for the people on both sides of the river!" Li Jie sighed at this time and said, this is the closest section of the Yellow River to Kaifeng, he and Zhu Biao have inspected Kaifeng City, and the first stop is to run to enjoy the majesty of the Yellow River.

"On the river? This statement is new, but it is also very accurate, according to the official report of the river management, the sediment brought by the Yellow River every year silts up the river, so that the river continues to rise, and even the riverbed is higher than Kaifeng City, they can only continue to strengthen the river embankment, but it is not a way to go on like this! Zhu Biao said with a worried look at the end.

"Strengthening the embankment alone can only treat the symptoms but not the root cause, and if this continues, the Yellow River will burst sooner or later, and then the river will be diverted, and the only way to build the embankment on both sides of the new river channel will be, and then the sediment will accumulate and lift the river, and start the previous cycle again!" Li Jie also said helplessly at this time.

In history, the diversion of the Yellow River is very frequent, and there is even a saying that "two breaks in three years, one diversion in a hundred years", only the relatively large diversion counted by later generations, there are more than 20 times, and the small diversion is countless, and even the estuary has undergone several changes, so it can be said that the history of the Yellow River is a history of flooding.

"Is there a solution to the flooding of the Yellow River?" Zhu Biao naturally asked Li Jie, since Li Jie appeared, Zhu Biao and Lao Zhu have developed a habit, as long as they encounter problems that cannot be solved, they like to ask Li Jie's opinion, and they often have unexpected gains.

"Yes, yes, but it's hard to do!" Li Jie shook his head slightly.

"What's the solution?" Zhu Biao was also shocked when he heard this, and asked.

"The reason why the Yellow River is difficult to control is that there is too much sediment, which causes the riverbed to continue to rise, so if you want to control the Yellow River, you must control the sediment, and most of these sediments are washed down from the middle and upper reaches of the Yellow River, that is, Shaanxi and the northwest. Li Jie said that at the end, he suddenly asked Zhu Biao rhetorically.

"Why?" Zhu Biao asked curiously again.

"In fact, before the Spring and Autumn Period and the Warring States Period, the Yellow River was not as turbid as it is now, because at that time, both sides of the river were full of dense forests and grasses, and the roots of these plants could fix the soil, and the rain did not easily wash the soil into the river, so the Yellow River at that time was called the Great River instead of the Yellow River."

Li Jie paused here and then said: "But later, the population gradually increased, especially from the Qin and Han dynasties, until the Sui and Tang dynasties, the Guanzhong Plain, coupled with the plateau in the northwest, the population continued to expand, and the land began to be reclaimed for arable land, resulting in bare soil, and the rain easily washed the sediment into the river, so that the river water naturally became turbid. ”

"Do you mean that unless the people in the middle and upper reaches of the Yellow River are removed and the land is planted with flowers and trees, the Yellow River can be restored to its original clarity?" Zhu Biao couldn't help but shake his head secretly in the end, this difficulty is simply too great, and it is simply an impossible task.

"In addition to this method, there is another way, which is to build a dam on the Yellow River, cut off the river water, so that the sediment is deposited in front of the dam, and then release the water regularly, and then the downstream water will be clear, and there is no need to worry about flooding." Li Jie replied again.

"Don't mess around, how can the Yellow River be cut off?" Zhu Biao glanced at Li Jie when he heard this, in his opinion, Li Jie was joking at all, unless there was a god to help, how could it be possible to cut off the Yellow River?

Li Jie smiled helplessly, he was clearly telling the truth, the Yellow River was controlled in history, that is, from the construction of the first dam on the Yellow River, that is, the construction of the Sanmenxia Dam, although the Sanmenxia Dam has many disputes, but it did control the flooding of the lower reaches of the Yellow River, benefiting countless people.

Of course, with the current state of technology, it would be fanciful to want to build a dam on the Yellow River, but the times are evolving, and in just a few hundred years, the technology to build a dam will appear, so it doesn't hurt to imagine it now.

"Uncle~, Uncle, look, I hit two rabbits!" At this moment, I suddenly heard someone shouting excitedly in the distance, and then I saw Zhu Youstew galloping on horseback, holding a bow and arrow in one hand and two rabbits with arrows in the other.

Today's inspection of the Yellow River is not only Zhu Biao and Li Jie, Zhu Youstew also personally accompanied him, but after all, he is a child, and he has a big playfulness, just now he came here and found that there are a lot of wild animals nearby, so he ran to hunt, saying that he wanted to hunt a few prey to entertain Li Jie and them.

"Yo~, this rabbit is quite fat, it just so happens that Li Jie has good cooking skills, how about you come to help us make a roast rabbit?" Zhu Biao looked at the rabbit in Zhu Youstew's hand and couldn't help laughing.

"Brother-in-law can cook?" Zhu Youstew was also a little surprised when he heard this.

"I just know a little bit about home cooking." Li Jie smiled and explained to the surprised Zhu Youstew.

"That's great, just now the guards said that they found the footprints of a wild boar nearby, and they have already chased them, I don't know if they can catch them." Zhu Youstew also laughed again when he heard this.

"Why are there so many wild things by the Yellow River?" Li Jie also asked curiously at this time, when he came to the river embankment just now, he saw some animals drinking water by the river, Zhu You stew can easily hit two hares, and there are also wild boar footprints, which shows that there are a large number of wild animals nearby.

"There are indeed a lot of wild things near Kaifeng, I heard the old people in the house say that there were more animals in the past, and there were even tigers, until the population increased, those animals were much less, but the Yellow River is too dangerous, many people are reluctant to live near the river embankment, so that wild things have also gathered by the river." Zhu Youstew replied again.

Li Jie couldn't help but sigh a little when he heard this, although the war brought heavy disasters to human beings, but it gave other animals a greater living space, and there were tigers in places like Kaifeng, which may not be unimaginable in later generations.

"Uncle, the Yellow River is seriously flooded, I don't know if the imperial court has any way to deal with it?" At this time, Zhu Youstew also asked about the flood, which made Li Jie and Zhu Biao also look at each other in surprise, and the evaluation of Zhu Youstew in their hearts also improved again.

"The flooding of the Yellow River is a chronic disease, and the imperial court can only allocate manpower to build river embankments and dredge waterways, and it is too difficult to completely solve it." Zhu Biao replied with a sigh at this time.

"Actually, just now His Highness and I were also talking about the problem of the Yellow River flooding, but there was no good solution." Li Jie also said at this time.

Zhu Youwei also showed a disappointed look when he heard this: "The Yellow River flood not only suffers the people, but Kaifeng City is flooded every year, for example, last summer, because of too much rain, the river water did not cross the embankment, and as a result, the entire Kaifeng City was flooded, and even the water in the palace was more than a foot deep. ”

Hearing Zhu You's stew, Li Jie couldn't help but feel some sympathy, Zhou Wangzhi Kaifeng, maybe in the eyes of others, Kaifeng is a good place, after all, it is known as the ancient capital of the Eight Dynasties, but only the people in Zhou Wangfu know that Kaifeng is all good, but it is always flooded, and the houses in the house must be overhauled every few years, otherwise they can't resist blisters at all.

In addition, Li Jie also knew that at the end of the Ming Dynasty, when Li Zicheng opened the seal, he led the Yellow River to flood Kaifeng again, but the last king of Zhou stepped on the stagnant water to withstand the attack of the righteous army, forcing Li Zicheng to withdraw the army, but the last king of Zhou also became ill, and finally died in the palace of the king of Zhou, which was full of water, and it was regarded as a retirement with the Ming Dynasty.
