After being reborn as a man, the woman improved her family's fortunes through education.

After passing through several prefectures, the river patrol team temporarily stopped in Shu County.

Here stands the Du'an Weir, which was built before the Common Era.

Du'an Weir is located on the Minjiang River, only a little over a hundred miles from Shu County.

The Du'an Weir irrigates the fields, a great project that benefits the people and is also the progenitor of world water conservancy culture.

Even in later generations, this place remained a very important water conservancy project and a water conservancy hub.

It consists of three main parts: the Fish Mouth Diversion Dam, the Feisha Weir Spillway, and the Baopingkou Inlet, as well as auxiliary parts such as the Baizhang Dam and the Renzi Dam.

The Du'an Weir effectively solved problems such as automatic diversion of river water, automatic sand removal, and control of water inflow, eliminating most of the flood hazards.

This place was also the most important part of the Ministry of Works' inspection, and Minister Wu decided to set up camp here and stay for a while longer.

After thoroughly inspecting the Du'an Weir, the inspection was basically more than halfway complete.

The "Du'an Weir" is also called the "Golden Embankment". It is described as "a bamboo cage made of split bamboo, three feet in diameter, filled with stones, and piled up to block the water". It is called "Jianwei".

“Every year, the Dujiangyan Irrigation System was improved, and a stone snake was used to divert water from the river to irrigate the fields of several counties.”

Every year, the Ministry of Works sends officials to inspect and manage the area, addressing any problems as early as possible.

Du'an Weir makes full use of the local geographical conditions of high northwest and low southeast, and takes advantage of the special topography, water veins and water flow at the river outlet to guide the water without dams and irrigate by gravity.

It makes dikes, water diversion, flood discharge, sediment removal, and flow control interdependent and form a system, ensuring the full realization of the comprehensive benefits of flood control, irrigation, water transport, and social water use.

Upon arriving at Du'an Weir, Mr. Sun gave Jiang Wenqing a systematic explanation of the area's construction history and key management techniques.

Jiang Wenqing didn't pay much attention at first, but after learning that this place had been the site of more than a dozen dynasties, he became more serious about it.

Seeing that he had achieved his goal of popularizing science, Mr. Sun stopped talking. There was too much to learn about water conservancy, and his own father wouldn't be able to absorb it all if he talked too much.

It's nothing more than something to hear and forget; there's no need for it. I won't actually be transferred to the Ministry of Works. Knowing what I just said is enough.

Moreover, there is already a member of the Jiang family in the Ministry of Works, holding the position of Vice Minister. It is unlikely that another county magistrate would be transferred into the Ministry of Works.

Although Jiang Wenqing had heard a lot about the Du'an Weir from Mr. Sun, compared with the accompanying officials who came from the Ministry of Works, he really only had a superficial understanding.

On the second day after arriving at Du'an Weir, Minister Wu led several subordinates from the Ministry of Works to inspect the weir.

It wasn't that he deliberately didn't bring the fourth prince; rather, the fourth prince had been inquiring about the upcoming itinerary ever since they arrived in Du'an Yan.

The following itinerary wasn't some confidential or important matter of the imperial court; it was just that they didn't want local officials to get the news in advance and put on a grand show to welcome them.

But since the fourth prince, who was acting as an assistant official, had asked, Minister Wu had no reason not to answer.

However, after learning about the upcoming itinerary, the Fourth Prince made a request that infuriated Minister Wu.

The Fourth Prince, Zhao Hongsheng, is leaving the team!

Although this inspection didn't expect this nobleman to do anything or contribute anything, he should at least stay in the ranks obediently!

It was supposed to be an easy victory, a simple trip that would have earned you a commendation before the Emperor, but you had to create trouble for yourself.

This is not just a problem that makes things difficult for Minister Wu; to put it more seriously, it is dereliction of duty or even disobeying an imperial edict!

Minister Wu was very tired, but he also had a sense of "as expected" because his mind had never been at peace throughout the journey.

The further he traveled, the more intense this feeling of unease became. Today, Minister Wu was like an old man who had finally waited for the other shoe to drop.

My heart doesn't need to be constantly on edge anymore, because it's completely dead.

Minister Wu suppressed his anger. He had tried to persuade him and reason with him. Did he expect a minister like himself to kneel down and beg?

Don't even mention the Fourth Prince; even if he were to stand before the Crown Prince one day, a high-ranking official must still possess the pride and integrity of a high-ranking official.

Want to make them bow down? Sure, either you're in the right, or you're the true ruler of the world.

Otherwise, treating court officials like fools and servants is absolutely intolerable!

Even if they are household slaves, they are still the household slaves of the Great Zhou Emperor, not the household slaves of any particular prince or grandson!

As a court official favored by the emperor, Minister Wu had both the confidence and the ability to do so.

With an emperor who trusts him implicitly and without any entanglement of imperial power, a loyal minister, a pure royalist, can absolutely have this kind of confidence.

"My lord, Minister Wu has led his men to Du'an Weir. Are you really not going to go and take a look?"

Xiao Dezi was a little intimidated by Minister Wu's imposing manner. If a minister were to impeach him, his master would be in serious trouble.

Oh no, I'm starting to regret giving my master this advice. This mission might be in serious trouble.

Xiao Dezi was filled with anxiety, but the Fourth Prince Zhao Hongsheng remained calm: "Don't worry, I know what I'm doing."

Two girls dressed as women served Zhao Hongsheng, one on each side, one pouring tea and the other peeling grapes.

Hmm, eating fruit and hot tea together, I'm really not afraid of getting an upset stomach.

Xiao Dezi thought to himself, but of course he didn't dare to voice any more opinions. He could only follow his master's lead step by step.

If we're leaving the group, should we go by water or land?

There is no shortage of boats here, but there is no way there are any official boats of this size available.

A ship of this size cannot be arbitrarily deployed even by a prince without a special order.

After all, this is an official ship that can carry hundreds of soldiers and can be armed into a warship at any time.

If the fleet was really mobilized at will, and the ships traveled along the river into the canal and then along the canal into Tongzhou and the capital, what difference would that be from treason?

Even a eunuch like Xiao Dezi understands this principle, so his master surely does too. Therefore, the only option left is to settle for a small boat or travel by land.

It is easy to go from frugality to extravagance, but difficult to go from extravagance to frugality. Would the master be willing to do that?

Others might not know, but for Zhao Hongsheng, who practically had the top deck all to himself, this ship was exceptionally spacious and comfortable.

Zhao Hongsheng knew he couldn't move other official ships, but he could move the one he was standing on.

After all, this ship's itinerary and purpose have already been recorded, and it will not take on any other missions before returning to the capital to report.

During river patrols, this boat was used exclusively by the Ministry of Works' patrol teams.

"When Minister Wu returns from his inspection of the Du'an Weir, have him come to see me."

Zhao Hongsheng took a sip of hot tea, ate a peeled grape, and said calmly.

"Yes, this servant will go to the dock and wait. As soon as Lord Wu returns, this servant will bring him to see you, Master!"
