It was the height of summer, and the mud-like water of the Yellow River was slowly flowing through the river. This Yellow River course is not the river course after the Yellow River seized Huai, but the old road of the Song Dynasty.

In fact, the so-called Song Dynasty road has been abandoned for many years, although the river embankment that had not been repaired for hundreds of years has long since collapsed, and the former river channel is also scattered with large and small ponds, many of which have been reclaimed into fertile land. But after more than three years of repairing, the Yellow River, which had been abandoned for hundreds of years, was re-dug and restored to its original course a few years ago with a loud bang on the embankment and a deafening explosion.

The river flows slowly along the renovated river to Bohai Bay.

With this remediation, the Yellow River will remain stable for at least 400 years, if not longer, and in the future, when the cost of cement falls, a more solid dam will replace the rammed earth dam.

On the south bank of the Yellow River, Zhu Jishi, dressed in light-colored clothes, was walking by the river, followed by more than a dozen people who looked like civil and military officials. Behind is a large group of Imperial Forest Army. The fields on both sides of the Yellow River are lined with trees of all sizes and weeds half a man deep, and occasionally flocks of birds can be seen flying among the grass and trees. The land within 5 miles on both sides of the Yellow River is barren, and there is a river dam five miles away, which is the second river dam, although its height and width are far less than the first river dam, but it avoids the possibility of regaining the Huai again after the dam bursts to the greatest extent.

It is precisely because of this that the fields that used to be rich are now extremely desolate, with only a few trees, birds, and wild things. But it's all worth it.

This is the first time that Zhu Mingzhong has come to the Yellow River after the Yellow River returned to its original path, and now this river finally no longer harms the Central Plains.

The reason why I came to Beizhili was to meet the family of a soldier who died in battle.

"This money is my son's life!"

Again, the old man's desperate cry sounded in Zhu Mingzhong's ears,

A few days ago, a report caused a sensation in Daming, who would have thought that the heartbroken words of a fallen soldier's father would cause such a big sensation.

"This money is my son's life!"

No matter how simple and straightforward the words are, they touched everyone's hearts, made people feel his heartache, and also felt the sacrifice of the soldiers, so that those who enjoyed the peaceful and prosperous times saw the price of the prosperous times!

This is the price of peace and prosperity!

In order to maintain this prosperous era, there are always too many soldiers who are paying and sacrificing in obscurity, and it is their sacrifices that have achieved all this and achieved this peaceful and prosperous era.

Although the war of Shaanxi has now come to an end, although Xinjiang and other places in later generations have not yet been recovered, and even Qinghai and Tibet are only expressions of surrender, not yet the territory of the Ming Dynasty. However, the troops gathered in Shaanxi have begun to adjust, and the nearly 50,000 troops of the Western Expedition originally gathered between Lanzhou and Guazhou have begun to retreat one after another, retreating to Xi'an.

They will be repairing in Xi'an, and even many soldiers will be discharged on the spot, and they will receive their own meritorious land there, and then become soldiers in the countryside and fight for the country...... At least in this era, Shaanxi is the border.

As for the vast majority of the local people in Shaanxi, they will move out of Shaanxi in the next few years.

This is not only to "make room" for the soldiers, but also to control the Yellow River. After all, for thousands of years, Shaanxi's land reclamation has exceeded the limits of land reclamation, and farmland needs to be returned to the land – as long as the land there is blocked, nature will help the vegetation there recover.

As for Xinjiang, Qinghai and Tibet, all the Ming army had to do was to wait patiently, wait for the time to come, and then they could recover these territories and completely incorporate them into the Ming provinces.

Now on the river dam, the grief-stricken father always comes to mind. How many fathers have lost their sons in this war?

There are only a few thousand!

Compared to any other war in history, the sacrifices of this war are extremely limited, and the cost of war is negligible.

"Hey, at least, let the world know about the sacrifice of soldiers!"

With a long sigh, Zhu Mingzhong threw too many emotions out of his heart, as an emperor, he should not be swayed by such emotions, even if it is sympathy, but ...... The sacrifice is worth it, and for the country, their sacrifice is worth it.

Walking from the dam of the Yellow River to the river, a mile, it took a while to get to the place, standing by the river, Zhu Mingzhong glanced at the river, and then said.

"A bowl or a teacup."

Afterwards, Zhu Mingzhong did not fake anyone's hands, but stood by the river by himself, bent down to take a glass of water.

"Look at the ...... of the water"

Holding the glass, Zhu Mingzhong looked back at Zhu Daxian, Qian Lei and several officials from the Ministry of Industry and the Ministry of Household behind him, and then said,

"What is this water image?"

"Back to Your Majesty, the water is like mud."

"Your Majesty, since ancient times, it has been said that the Yellow River water is a bowl of water, half a bowl of mud,"

"And where did this mud come from?"

Looking at Zhu Daxian and Qian Lei, Zhu Mingzhong asked rhetorically. Faced with these two questions, the two of them suddenly became dumb.

"Back to Your Majesty, most of the sediment of the Yellow River comes from Shaanxi, the land in northern Shaanxi is barren, and the erosion of rainwater causes soil erosion to mix into the river, and finally flows into the Yellow River,"

Standing up and taking the initiative to explain was Zhu Zhangpei, a foreigner from the Ministry of Works, who should have died in the "Wailing Temple Case" a few years ago. However, because of the success of Zheng Chenggong's Northern Expedition, the "Crying Temple Case" in history disappeared into history.

However, this does not mean that there is no "Wailing Temple Case", in fact, when the imperial examination was abolished in the third year of Xingqian, there was also a "Crying Temple Case".

"Crying Temple" is a long-standing custom in Suzhou. The local economy is developed, the humanities are gathered, from the family of Yin Shi, the scholars have become an important social supervision force, when the government has illegal things and improper behavior, the scholars gather in the Temple of Literature every time, make "Juan Tang Wen", cry to the ancestor Confucius Sage, and then convene the people to declare to the higher government, in the Ming Dynasty, the "crying temple" declaration of many people can often make the government dare not underestimate and adopt. But in the new dynasty, the old imperial calendar hit the south wall. When the imperial court decreed the abolition of the imperial examination, Suzhou also had hundreds of Xiucai "crying temples", but it was different from another "crying temple case" in the 18th year of Shunzhi, which led to the killing of 121 people, including 18 people and Xiucai. More than 190 talented people were dismissed from their fame and exiled overseas on the grounds of "gathering crowds to make trouble".

For this, people may be surprised by the "harshness" of the Xingqian Dynasty, but compared with the tyranny of the Manchu Qing Dynasty, they have been relieved, after all, at the beginning, including Zhu Zhangpei, who had already come out, thought that those people would at least take the lead will be beheaded.

However, it was also from that time that the imperial court clearly told the people of the world that they could publish articles in the newspaper to express their opinions, and they could also submit petitions through formal channels, but it was absolutely impossible to threaten the government by means of "crying temple" declaration. Even if it is justified, it is necessary to investigate the illegal act before dealing with other things.

The old imperial calendar can't work in the new dynasty!

This point is naturally very clear to Zhu Zhangpei, who has returned to the Ming court as early as Nanjing, and this is also the reason why he re-studied practical learning at the age of half a hundred, at least this "soil erosion" is a new knowledge. However, for this knowledge, it is obvious that Qian Lei and Zhu Daxian are laymen.

"Zhu Zhangpei, you go on......"

"Obey."

After getting His Majesty's permission, Zhu Zhangpei continued.

"Your Majesty, this "soil erosion" is a new science, but although it is a new science, it is also a new science...... In the pre-Qin period, it was called "peaceful control of water and soil...... The ancient sages had this idea that forests can maintain water and soil for a long time. ...... "Knowing the forest, the prince is appropriate." Geedo"; "Forbidden Forest. Jeongyoshi"; "Ganlin. No Linli; There is no blame for it. "Viewing the ban on deforestation as a sign of "auspiciousness" and the wanton destruction of forests as a "vicious" act. It can be seen that the ancient ancestors have long recognized that forest vegetation has the functions of regulating microclimate, maintaining water and soil, preventing soil erosion, and improving the ecological environment......"

Zhu Zhangpei's answer made Zhu Mingzhong nod his head thoughtfully. Although he is a traverser, Zhu Mingzhong is not the kind of all-rounder who knows everything and can do everything. In science, of course, there is knowledge that is hundreds of years ahead of the times, but in some academics, he can only give some enlightenment, and as for the subsequent development, it still needs to rely on the development of the people of this era themselves. Just like "soil erosion", you come up with an idea by yourself, and then naturally there are wise people of this era to prove it, study it, and finally come up with a solution to the problem.

"This Shaanxi is thousands of miles away from this time, and there is so much sediment in this river, how can it be brought from Shaanxi, this statement is really ridiculous!"

Qian Lei said in disbelief.

"The land use form and vegetation cover in the middle reaches of the Yellow River are still one of the important factors leading to the siltation and even overflow diversion of the lower reaches of the Yellow River, and they should not be ignored by denying their direct triggering effect."

Facing Ge Fu's rebuttal, Zhu Zhangpei replied unceremoniously.

"Besides, this is not speculation, but it is proven by the research of Qinghe Academy!"

"Oh? Shaanxi has just been recovered, how does the academy prove it? ”

Zhu Mingzhong didn't say anything about their argument, after all, he knew that what Zhu Zhangpei said was the truth, after all, scientific research in later generations had proved all this. However, he was also a little curious about how the academy proved all this.

"Back to Qian Gefu, I wonder if Gefu has any impression of the drought since the third year of Chongzhen?"

Chongzhen has been in drought for three years!

How could it not be impressed!

But anyone who has experienced that era, how can they not have the impression that Chongzhen is in drought. This is the longest-lasting, most extensive, and most severe drought in China in the past 500 years, with thousands of miles of red land, rivers cut off, wells and springs dried up, grass in the wild, grass dried up, starvation everywhere, and cannibalism.

The reason why they can remember everything is not because of the cannibalism caused by the lack of rain in Shaanxi for several years, nor because of the starvation there everywhere, but because of Li Zicheng, because of the Western bandits, because of the "Jiashen Heavenly Change", because of the millions of rogues from Shaanxi.

It was those millions of rogues who made the emperor lose his life, and even the Han people's rivers and mountains were almost lost to the Manchus, allowing the Manchus to take advantage of them. Even, even their family members and friends died directly or indirectly because of the Western bandits, if there were no Western bandits, how could the Manchus have been able to enter the customs? How could their family and friends die under the butcher's knife of the Manchus?

Many times, people are always able to remember tragic things. Even now that I think about it, they are also sentimental, which is a pain in the face of many people, but now that people ask this directly, that look naturally becomes unnatural.

Seeing Qian Lei's cold face and nodded, Zhu Zhangpei continued.

"It may be that everyone only saw the drought at that time, but they did not see that the water of the Yellow River was much clearer that year, and according to the geographical records of the Caoyun Yamen and the government offices along the river, the sediment in the river has decreased sharply. The climate of Shaanxi and other places is due to the fact that Shaanxi has been dry for several years, with little rain and snow, and according to historical records, if the sediment in the river increases, a few months ago, heavy rain must have fallen in various parts of Shaanxi......"

Then Zhu Zhangpei continued to explain what is "soil and water conservation", what is "the ability of vegetation to conserve soil", and other scientific terms are new to Qian Lei and others, and even for the vast majority of people in this era, they are also fresh, after all, this is an emerging discipline. In the end, Zhu Zhangpei even picked up the water and made an experiment, a basin of water was poured on the soil without vegetation, and the water rushed to the soil into the river, and if there was vegetation, the water was sucked into the ground.

The two completely different results really made Qian Lei and Zhu Daxian stunned, and after a long time, Zhu Daxian said.

"Oh, the minister seems to remember, in Qinghe Academy, there seems to be a laboratory, which is dedicated to this experiment, it seems to be ......"

Looking at His Majesty, Zhu Daxian complimented.

"That laboratory was funded by His Majesty, so we have figured out where the sediment in the Yellow River comes from, and in the future, we only need to plant trees in Shaanxi, wouldn't it be possible to maintain the water and soil, and the water of the Yellow River will become clear?"

The Yellow River is clear, and the saints are out!

Suddenly, Zhu Daxian seemed to understand why His Majesty would set up this laboratory, and why His Majesty was so stubborn about the immigration from Shaanxi.

At the end of the day, this is a good and no harm to Your Majesty! That's why Your Majesty has persevered until now. No concessions were made.

"Planting trees? Clear water? ”

Shaking his head, Zhu Mingzhong looked at the Yellow River, was silent for a moment, and then said.

"In the pre-Qin period, the north of the Wei River was full of primeval forests and grasslands, and now it is all arable land, the local soil erosion is serious, and the land is very barren. Don't you see what's going on there? ”
