Zhu Yunxi, who was a devoted minister, kept Pei Benzhi in Lanyang County for several days.

In the past few days, the two talked a lot and had a great time.

In Zhu Yunxi's understanding, Pei Benzhi is capable of taking on big responsibilities.

From the current disaster in Liufu to the current situation in Henan Province, they have talked about the changes in the direction of the entire imperial court's governance over the years.

Obviously, such an iron-necked county magistrate who has not changed his position for eight years has not forgotten the direction of the government and the opposition because of the pressure of his official rank.

Although he was humble and did not dare to worry about the country, Pei Benzhi was a capable minister who pursued his own affairs in his position but did not let his family, country and world rule.

"If you live high in a temple, you worry about its people; if you live far away from the rivers and lakes, you worry about your ruler."

"Pei Benzhi, Your Highness read it right."

At the top of Lanyang City, Pan Deshan accompanied Zhu Yunxi and looked into the distance with him. On the official roads that had been cleared one after another in the past few days, there were the people of Chenliu County Magistrate Pei Benzhi who had gone away.

The emperor's grandson rewarded Pei Benzhi with a bicycle frame.

This incident happened not long ago today, and its meaning is already known to everyone on the road.

Pan Deshan has been conducting his own water-sweeping experiment in Lanyang County for the past few days. He feels that he may take over the entire Yellow River management in the future. He has been supportive of the emperor's reuse of Pei Benzhi from the beginning.

.

At this time, there is no harm in saying a good word or two for Pei Benzhi.

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

Zhu Yunxi put one hand on the city wall and put the other behind his back, looking at Pei Benzhi's group of people walking away on the official road, pretending to look over his shoulder at Pan Deshan.

His eyes were more thoughtful, as if he wanted to see through Pan Deshan's entire being.

This made Pan Deshan couldn't help but lower his head silently.

Zhu Yunxi said quietly: "How Pei Benzhi should be used still needs to be reported to the court."

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

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

Pan Deshan nodded immediately and said: "Everything is ready to go back to Your Highness. I'm just waiting for Your Highness and the accompanying officials to come over and take a look."

Zhu Yunxi smiled and said: "To become famous and achieve great success will last forever. On this occasion, let's go together."

Pan Deshan bowed and gave way, feeling a little more hopeful in his heart.

Soon.

A place with a high slope outside Lanyang County has been cleared by the county government officials and officers and soldiers. In addition to the busy Lifu, a group of people are still staying in Lanyang County, waiting for the emperor's grandson to summon him at any time to inquire about the administration.

The accompanying officials.

At this time, everyone focused their attention on the two waterways up and down the slope that were obviously artificially shaped. Everyone whispered and pointed at the waterway built with loess and covered with sand downstream of the slope.

.

This time, the accompanying officials who followed Zhu Yunxi on his western tour and provided relief to the six prefectures were not just one or two people from each ministry, but a large number of officials from each ministry and yamen.

Now beside this sloping waterway.

In particular, several other officials from the Ministry of Industry were sought after like never before, and were surrounded by a group of accompanying colleagues asking about various matters.

"Brother Guan, you are also from the Ministry of Industry. Do you think Pan Langzhong's river control method of flushing water with sand is really effective?"

An accompanying official from the Ministry of Revenue asked the director of the Ministry of Works, whose surname was Guan, with worried eyes.

From time to time, the people in the household looked towards one of the two waterways, which was blocked by several crossings.

According to Pan Deshan's previous explanation to them, those barriers are the dams that will be built on the Yellow River in the future to restrict the river water, store the river water, and then increase the speed of the water flow. In conjunction with the Yellow River on the downstream plain of Sanmenxia,

The shrinkage of the river channel continuously washes away the silt and accumulates sand in the river bed, which plays the role of digging the river bed deeply and suppressing floods.

The logic seems feasible.

However, when the people in any household department present saw the blocks that represented the dam, they didn't expect to see piles of real money and silver that had to be spent out of the household department before they could turn into large blocks on the Yellow River.

Dam.

Not to mention the lower reaches of the Yellow River, the layers of levees that stretch for thousands of miles to restrict the river water.

These are all things that can only be seen if real money is spent.

The person in charge of the Ministry of Industry hesitated for a moment, then finally nodded and shook his head and said: "I have been discussing Pan Langzhong's method of confining water to wash away sand in the past few days. It stands to reason that as long as the water flow is fast enough, the Yellow River can be rolled up.

Silt and sand accumulation under the riverbed downstream."

The accompanying officials surrounding the Ministry of Industry stopped their discussions after hearing this, and turned their attention to the person in charge.

The person in charge of the Ministry of Industry did not keep his colleagues waiting for a long time, and said with some uncertainty: "It's just that the Yellow River has never been controlled by human power. It is different every moment. What I am most worried about right now is whether this method can be used.

Applied to the Yellow River.

Or maybe, repairing the dams on the Yellow River and repairing the river embankments downstream can maintain peace for a while. But once a flood that has not been seen in a century comes, will it be able to withstand it?

After all, even Pan Langzhong knows that Huang He is like a human being, moody and affected by the weather. No one can figure out what Huang He’s temper is so far. If he does everything today, can he guarantee success in the future?"

As the chief officer spoke out the thoughts of the remaining officials accompanying the Ministry of Industry, there was a burst of sighs and recognition at the scene.

If the Yellow River could accomplish the task of all eternity with just one day's work, then the Yellow River would not need to be vigorously tormented by the imperial court every year.

"In this case, let Pan Deshan try a few more times. The water poured on this waterway can be tested again and again to see how much it can withstand?"

Just when everyone was having a heated discussion.

Zhu Yunxi's voice came quietly from behind everyone.

Everyone was slightly shocked, and quickly turned around, only to see that the emperor's grandson had appeared here at some time, leading Pan Deshan, a doctor from the Ministry of Industry's Dushui Qingli Division.

"I see you, Your Highness."

This feeling of whispering to classmates while the old teacher is away in class, but not wanting to be caught by the teacher appearing from behind the class, really makes everyone feel panicked.

Zhu Yunxi waved his hand casually: "On matters related to the country, there will naturally be different opinions, and I can tolerate disputes. However, if it is verified to be correct, it means that it will be a good solution in a difficult situation. No matter what

White cat or black cat, as long as it can catch mice, it is a good cat! What a good idea!"

All the accompanying officials breathed a sigh of relief, and they all bowed and clasped their fists.

"Your Highness is wise, and I will obey your orders."

Zhu Yunxi looked sideways at Pan Deshan beside him: "Just go ahead and do it, I will just watch from here."

Pan Deshan had many thoughts in his heart.

In the end, they all gave a calm reply: "I will never disappoint His Highness!"

After saying that, Pan Deshan waved his robe and turned around, crossing the crowd and reaching the top of the waterway that had been built and erected long ago.

At the source, there was a large tank filled with water prepared by Pan Deshan.

Pan Deshan held his head high and raised his hands high: "I am fortunate to be appreciated by His Highness and present the method of beaming water to wash away the sand. Today, I have colleagues to watch and review. If there are any shortcomings, I hope you will take the time to point out."

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

Amid everyone's anticipation, Pan Deshan waved his hand, and several officers and soldiers immediately carried the smallest water tank to the source of the upper reaches of the waterway.

Pan Deshan said loudly: "This is a test based on the daily water volume of the Yellow River. Please take a look."

Following Pan Deshan's loud shout, the officers and soldiers tilted the water tank upstream of the waterway without simulated dams and multiple embankments. Immediately, the water column poured out of the tank and poured into the waterway.

The opening of the water tank is close to the top of the raised water channel. This is to better imitate the flow speed of the Yellow River, rather than rushing down in vain and losing reality.

Under the watchful eyes of everyone, the water flowed down bit by bit from the upper reaches of the waterway.

It flowed very fast all the way to a position comparable to the Sanmen Gorge of the Yellow River. The sediment on both sides of the waterway was continuously carried down by the water flow. Then the flow slowed down in vain, and the sediment carried from the upstream was deposited bit by bit in the downstream waterway.

When the water source is cut off upstream, the water flow downstream disperses, and the sediment in the downstream waterway has risen by half a minute visibly to the naked eye.

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

But Pan Deshan didn't stop and said loudly: "Everyone, what's next is a flood that happens once in fifty years, once in a hundred years, and once in a thousand years, and washes away the Yellow River channel that I want to build."

This is the highlight!

After Pan Deshan spoke, everyone held their breath almost subconsciously and looked at the waterway that was obviously narrower than the previous one and had a series of dams.

A flood that occurs only once in fifty years pours down.

The dam blocks and resists the 'flood peak', and even downstream of the 'Sanmenxia' position, the 'flood peak' weakens, but the flow speed is within a controllable range. The continuously surging water rolls up layers of sediment, and continues to wash away, until the water flow stops.

Next.

The waterways are intact!

As much as three to four percent of the sediment was washed away!

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

"This is a once-in-a-hundred-year flood, please take a look."

Pan Deshan's voice became louder and louder.

The accompanying officials present were already moving involuntarily, wanting to get closer to the experimental waterway and get a better view.
