Zhu Yunxi, who bowed to his subordinates, stayed Pei Benzhi in Lanyang County for several days.

In the past few days, the two talked a lot and talked happily.

In Zhu Yunxi's understanding, Pei Benzhi can take on a big responsibility.

From the disaster in the six provinces to the current situation in Henan Province, they have changed the direction of the entire imperial court for many years.

Obviously, such an iron-necked county magistrate who has not moved for eight years has not forgotten the direction of the wind up and down the government and the opposition because of the crushing of the official rank.

is humble and does not dare to forget the country, Pei Benzhi is a capable minister who seeks his own government in his position, but does not let his family and country go to the world.

"If you live in a temple, you will worry about its people, and if you are far away from the rivers and lakes, you will worry about its king."

"Pei Benzhi, Your Highness is not mistaken."

At the head of Lanyang City, Pan Deshan accompanied Zhu Yunxi, and looked into the distance with him, on the official road that had been cleared out one after another in the past few days, and Pei Ben, the county commander of Chenliu County, had gone away.

The imperial grandson rewarded the frame and gave it to Pei Benzhi.

This incident happened not long ago today, and its meaning is already known to everyone in Sima Zhao's heart.

Pan Deshan has been working on his own experiments in the past few days in Lanyang County, and he felt that he might have to take over the entire Yellow River affairs in the future, and he was supportive of Pei Benzhi from the beginning when he wanted to reuse Pei Benzhi.

At this time, it does not prevent Pei Benzhi from saying a good word or two.

What's more, these are words that echo His Highness's wishes.

Zhu Yunxi stomped on the city wall with one hand, and put the other behind his back, looking at Pei Benyi's pedestrians who were gradually moving away on the official road, and pretended to look at Pan Deshan.

His eyes were a little more thoughtful, as if he wanted to see through Pan Deshan's whole person.

This made Pan Deshan silently bow his head.

Zhu Yunxi said quietly: "How Pei Benzhi should be used, it still needs to be clarified by the imperial court."

Pan Deshan, who lowered his head, opened his mouth to explain.

Zhu Yunxi's voice came into his ears again: "I heard that your experiment is almost ready?"

Pan Deshan immediately nodded and said, "Back to Your Highness, everything is already ready, just wait for Your Highness and the accompanying officials to come over and take a look."

Zhu Yunxi smiled: "Fame and fame, merit is in the future, on this occasion, let's go together."

Pan Deshan bowed down to give way, and he had a little more expectation in his heart.

Not much.

A place with a high slope outside Lanyang County has been emptied by the county government officials and officers and soldiers. In addition to the busy Lifu at the scene, there were a group of officials who remained in Lanyang County, waiting for the imperial grandson to summon them at any time to inquire about the administration.

At this time, everyone turned their attention to the two waterways above and below the slope, which were obviously artificially shaped, and everyone whispered, pointing from time to time to point at the waterways built with loess and laid with sediment downstream of the slope.

The officials who accompanied Zhu Yunxi on his western tour and provided relief to the disaster in the six prefectures this time were not only one or two people from each ministry, but a large number of officials from each ministry, department, and yamen accompanied him.

At the moment next to this sloping waterway.

In particular, several other officials of the Ministry of Industry were sought after in the past, and they were surrounded by a group of accompanying colleagues to ask about various matters.

"Brother Guan, you are also from the Ministry of Industry, do you think Pan Langzhong's method of controlling the river with water and sand is really useful?"

….

An official accompanying the Ministry of Household Affairs looked worriedly and asked about the principal of the Ministry of Works.

From time to time, the people of the household looked at the two waterways, one of which had several cross-sectional waterways.

According to Pan Deshan's previous explanation to them, those obstacles are the dams to be built on the Yellow River in the future to restrain the river water, store the river water, and then raise the speed of the water. In addition, with the shrinkage of the Yellow River channel on the lower plain of Sanmenxia, the silt and sediment of the riverbed are constantly scoured, which plays the role of digging deep into the riverbed and leveling the flood.

[The problem of slow update of new chapters has finally been solved in the ability to change the source, here download huann.change the source, and view the latest chapters of this book on multiple sites at the same time. 】

The rationale seems to be plausible.

However, when the people in the household department saw that the one represented the blockage of the dam, they did not want to see that piles of real money and silver had to be spent from the household department before they could become dams on the Yellow River.

Not to mention the lower reaches of the Yellow River, the layers of embankments that stretch for thousands of miles to restrain the riverbed.

These are all things that can only be seen when real money is sprinkled out.

The head of the Ministry of Industry hesitated for a moment, then finally nodded and shook his head, "I have been discussing the method of binding water and washing sand in Pan Lang these days. It stands to reason that as long as the water is fast enough, it can sweep up the silt and sediment under the riverbed in the lower reaches of the Yellow River."

The accompanying officials surrounding the Ministry of Industry, after hearing the sound, stopped discussing one after another, and their eyes all turned to the side of the director.

The head of the Ministry of Industry did not let his colleagues wait for a long time, and said with some uncertainty: "It's just that how can the Yellow River be restrained by manpower, and every moment is different. What worries us most at the moment is whether this method can be applied to the Yellow River.

Or, at present, repairing the layers of dams on the Yellow River and repairing the embankments downstream can ensure peace for a while. But once a flood that has not been seen in a hundred years comes, can it resist it?

After all, even Pan Langzhong knows that the Yellow River is human-like, moody, and affected by the weather, and no one has been able to figure out what the temperament of the Yellow River is. If we are all about today, can we keep the work of the coming day?"

As the director Guan said the thoughts of the remaining officials accompanying the Ministry of Works, the scene could not help but sigh and agree.

If the Yellow River can be done in one day and can be done for all eternity, then the Yellow River will not need to be vigorously tossed by the imperial court every year.

"In that case, let Pan Deshan try a few more times, and compare the water poured on this waterway once at a time to see how much it can bear?"

Just when everyone is talking about it.

Zhu Yunxi's voice came silently from behind everyone.

Everyone's hearts were slightly shocked, and they hurriedly turned around, only to see that the emperor's grandson had already led Pan Deshan in the Ministry of Industry and the Ministry of Works, and he had already appeared here.

"Your Highness, your courtiers."

This feeling of being caught in the school while the old gentleman was not there to talk to his classmates, but he didn't want to be caught by the gentleman from the back of the school, really made everyone feel panicked.

Zhu Yunxi waved his hand casually: "When it comes to social affairs, there will naturally be different opinions, and loneliness can tolerate controversy. However, if the verification is correct, it means that it will be a good way to deal with all difficulties. Whether it's a white cat or a black cat, as long as it can catch a mouse, it's a good cat! What a way!"

….

The accompanying officials breathed a sigh of relief in their hearts and bowed down in unison and clasped their fists.

"Your Highness is wise, and your ministers obey orders."

Zhu Yunxi looked sideways at Pan Deshan beside him: "You can do it, Lone is watching here."

Pan Deshan's heart was filled with many feelings.

In the end, they all turned into a calm answer: "The minister will never disappoint His Highness!"

After saying that, Pan Deshan waved his robe and turned around, crossed the crowd, and reached the top of the waterway that had been laid down long ago.

At the early source, there was a large vat full of water prepared by Pan Deshan.

Pan Deshan held his head high and raised his hands high: "This official is fortunate to be appreciated by His Royal Highness, and he offers the method of washing water and sand. Today, I have to wait and see from your colleagues, and if there are any shortcomings, I hope you will take the time to give advice."

said that he wanted someone to give advice, but Pan Deshan's face was full of confidence.

In the expectation of everyone, Pan Deshan waved his hand, and immediately several officers and soldiers carried the smallest water tank to the upstream source of the waterway.

Pan Deshan said loudly: "This is a comparison of the Yellow River's weekday water volume test, you can see."

With a shout from Pan Deshan, the officers and men had already tilted the water tank upstream of the waterway, which did not simulate a dam or multiple embankments, and immediately the water column poured out of the tank and poured into the waterway.

The mouth of the water tank is attached to the top of the raised waterway, which is to better reflect the water of the Yellow River

The flow of the current, rather than a vain torrent, lost in reality.

Under the gaze of the crowd, the water flowed down the upper reaches of the waterway little by little.

The sediment on both sides of the waterway was carried down by the current, and then the flow slowed down in vain, and the sediment carried from the upstream was deposited in the downstream waterway little by little.

When the upstream water source is cut off, the downstream water dissipates, and the sediment in the downstream waterway is visibly raised by half a point.

The results of the test are very clear, and the reasons for the continuous elevation of the riverbed in the lower reaches of the Yellow River are clearly simulated.

But Pan Deshan kept talking, and said loudly: "Ladies and gentlemen, the next thing is the great flood that will occur once in 50 years, once in 100 years, and once in 1,000 years, and wash away the Yellow River channel that this official wants to build."

That's the main thing!

As Pan Deshan spoke, everyone almost subconsciously held their breath and looked at the waterway that was obviously narrower than the previous one and had one dam after another.

The flood that occurs once in 50 years is pouring down.

The dam blocks and resists the 'flood peak, and even 'Sanmenxia, located downstream,' the flood peak, weakened, but the flow rate is in a controllable range, and the continuous agitation of the water flow rolls up layers of sediment, and the continuous erosion until the water stops.

The waterways are intact!

The sediment washes out as much as three or four of them!

At the end of the first test, the officers and men quickly sucked up the water stored behind the upstream dam and re-laid the sediment in the downstream waterway.

"This is a once-in-a-century flood, so look."

Pan Deshan's voice became louder and louder.

The accompanying officials present were already involuntarily moving their feet, wanting to be closer to the waterway of the test and look more clear.

More water, faster flow, more momentum.

The accompanying officials formed a group, constantly moving from upstream to downstream.

….

The embankment is unobstructed, the river channel is stable, and the water flow below Sanmenxia is strictly controlled below the height of the embankment, and the sediment rolls like slurry, constantly being washed away by the water flowing down from the upstream one by one.

In the end, the waterway was intact, and more than half of the sediment downstream had been washed away.

Someone was already gasping.

Although the so-called test in front of us is somewhat different from the real Yellow River, the reason is the same.

Pan Deshan did not give these people more respite.

For the third and final time, the simulation of a once-in-a-millennium flood has been vented down from the upper reaches of the waterway.

The waterways began to tremble with the naked eye.

The dam also frothes, but it is still firm in the raging current.

Downstream, the whole riverbed seemed to be rolled up, and the river was covered with sediment, and at last it overflowed the embankment built by Pande's good management of the river, and in some places it finally burst after being washed away by the first two floods.

Soon, however, the lattice behind the embankment blocked the water gushing out of the embankment. The remote embankment in the distance protected the last rushing momentum of the water.

Several officers and soldiers, pretending to follow Pan Deshan's instructions, began to play with mud behind the location of the embankment breach, and repaired a moon embankment to block the breach.

When the officers and soldiers were playing in muddy water, the water finally flowed clean.

"The sediment in the river has been almost washed away!"

"Calculate the width of the breach, how wide it will be above the Yellow River."

"This law...... This method ......"

"Can it really be done?"

"Figured it out! It's done!"

"When a great flood occurs once in a thousand years, the width of the breach is one hundred and fifty zhang."

"This method works!"

This is not the real Yellow River, this is not the Yellow River embankment that is visible not far away.

Countless accompanying officials kept muttering in their hearts, but the waterways built in front of them compared to the Yellow River were clearly placed in front of them

。

The reasoning is the same.

The basis of Pande's method of governing the river has also been repeated again and again.

Even the officials accompanying the Ministry of Works, who were hesitant at first, began to doubt whether their hesitation was correct.

Pan Deshan, who was standing on the slope, was also excited at this time.

There is no problem with his own method of governing the river, it is real and feasible. What really excited him was the shock and surprise expressed by these accompanying colleagues from the DPRK and China, as well as the admiring glances cast at him from time to time, which made Pan Deshan begin to believe again and again that his method of governing the river would be used on both sides of the Yellow River for thousands of miles.

Zhu Yunxi witnessed all the experiments and observed the changes in the attitudes of these accompanying officials.

In a brief silence after shock and surprise.

Zhu Yunxi said softly: "Everyone, Pan De's method of governing the river is applied to you today, do you still have doubts?"

After a continuation of silence, the accompanying officials spoke.

"Pan Gong is a great talent, the great river of the country, this is peaceful, the prosperous era continues, the ministers are His Royal Highness, for Your Majesty, and for Daming!"

In a congratulatory voice, Tian Mai came unexpectedly.

….

In Zhu Yunxi's afterglow, Tian Mai walked lightly and came to his side, which surprised him slightly.

Tian Mai whispered, "Your Highness, His Royal Highness King Zhou has come down and said that if I want to see Your Highness." Zhou Wang ...... I only brought a team of palace guards, and there were no people around."

After informing the emperor of the news, Tian Mai added more and more quietly.

Zhu Yunxi frowned slightly, glanced at the officials in front of him, did not open his mouth to explain, just waved his hand, and glanced at Pan Deshan on the slope, and then left silently with Tian Mai under the gaze of the excited hundred officials.

The accompanying officials, even if they were curious in their hearts, when was there something more important than verifying Pande's method of governing the river that would allow Taisun to leave here.

But professional ethics tell them what to ask and what not to ask.

Since the grandson doesn't care about them, the next thing is a carnival.

In the blink of an eye, Pan Deshan, who was standing on the slope, was overwhelmed by his colleagues who were suddenly more enthusiastic.

And Zhu Yunxi, who was far away, had a solemn expression.

He never went to Kaifeng Mansion to look for his Uncle Zhou, but the other party didn't know why, but he actually came to the door in person.

waited for Zhu Yunxi to enter the county government of Lanyang County.

On the main hall of the county government, I saw Zhu Hu, the king of Zhou, wearing a dark blue regular dress.

Zhu Yunxi's face immediately showed a smile, opened his arms, and walked quickly all the way to Zhu Hu's back, with his arms folded and arched his hands: "It turned out that the fifth uncle is here, and the nephew is not welcome, I hope the fifth uncle will forgive me."

Zhu Huan turned around, looked at Zhu Yunxi, who had done a thorough and impeccable manner, with a smile on his face, stretched out his hand to help him up, and then frowned slightly, and said unhappily: "This is not at home, your western tour this time is a messenger who has been ordered by the emperor, and it should be Uncle Wang who gave you a gift."

As he spoke, Zhu Hu was about to bow.

Zhu Yunxi immediately held this one, and said with an uneasy face, "What is the fifth uncle going to do? This is going to torment my nephew!"

Zhu Hu also took advantage of the situation to stand up straight, but it was the anti-guest who pulled Zhu Yunxi to sit aside.

Then, carrying the teapot that should have been given when he first came earlier, he poured a cup of tea for Zhu Yunxi.

Push the teacup to Zhu Yunxi's hand.

Zhu Hu opened his mouth and said: "I heard that you were ordered to tour the west this time, and also did the work of helping the six mansions, and set up a bureau in Xuzhou Mansion to exterminate thousands of bandits, which can be described as the leader of the clan, and my family is lucky."

Zhu Yunxi raised his eyebrows, held the teacup with both hands, and took a slow sip: "It's just some bold fanatics who have been bewitched and fascinated by the evil god of Yin Society, and it is really difficult to set things right, so they can only be punished with thunder."

"That's how it should be!" Zhu Hu clapped his hands in approval.

Zhu Yunxi's eyes suddenly turned and looked at Zhu Hu: "I don't know what happened when the fifth uncle came to Lanyang to look for his nephew?" However, this time the palace was also affected

？」

Zhu Huan smiled and looked at Zhu Yunxi: "The old man has pity on your Uncle Wang, when he was in the domain, he gave me the old Song Palace, and it has also been repaired over the years, and there is a Kaifeng city wall to resist it, but he has never suffered."

As he spoke, Zhu Hu also took a sip of tea, and quietly raised his eyes to look at Zhu Yunxi by taking the opportunity to raise his glass.

Zhu Yunxi was silent, sipping the tea left by Cao Zhisheng, that is, he made up his mind that as long as the fifth uncle took the initiative to speak, he would never mention it to the right thing.

……

"Fifth uncle, my nephew will bring you tea."

After the water in the teapot was fully replenished three times, Zhu Hu finally couldn't stand the eldest nephew's courtesy, and waved his hand to refuse the eldest nephew's persuasion of tea.

Zhu Huan's eyes explained sincerely: "Eldest nephew, if you drink your fifth uncle again, you won't be able to walk."

Zhu Yunxi smiled slightly: "You are an elder, if your nephew loses the rules of etiquette, when the time comes, when he returns to Yingtian, not only will my father beat me, but even the old man will probably reprimand me."

After finishing speaking, Zhu Yunxi looked at Zhu Hu with a look in his eyes.

Zhu Hu saw that he was talking here, knowing that if he didn't open his mouth today, this kid would not be able to talk to himself if he was killed, and he could only take the initiative to attack now.

Thinking of this, Zhu Hu coughed lightly: "Actually, the fifth uncle is here to offer medicine and prescriptions."
