Xiong Wu's sudden courtesy was definitely up to no good. Su Ze quickly said: "What are you going to do?"

Xiong Wu pretended to be helpless and said: "Ms. Su, is Xiong so miserable in your heart?"

Xiong Wu looked like a scoundrel, but he pretended to be polite when speaking. Su Ze had goosebumps all over his body.

He pulled the reins and said: "If you want to go, just follow. If you have any bad intentions, I will throw you into Jianxi!"

The two gunmen following Su Ze showed murderous smiles.

Xiong Wu immediately said: "Mr. Su, I am sincerely devoted to Mingyue!"

Su Ze was too lazy to pay attention to him, and headed upstream of Jianxi River with his shotgun.

Xiong Wu just laughed and quickly followed Su Ze's horse, not far behind.

The flow direction of Jianxi is not complicated. It is a tributary of the Minjiang River flowing from west to east into the sea.

Although it is called a creek, the water surface of Jianxi is still very wide, but the water becomes turbid as you go upstream.

When he reached the boundary marker of Changning Guard, Su Ze pointed upstream and said:

"Is the government-run mine ahead?"

Xiong Wu didn't know when he followed up, and continued what Su Ze said: "In front of this is the government-run lime mine. The black smoke seen by the young husband is the blast furnace erected for calcining lime."

Sure enough, Su Ze saw a few smoke pillars in front of him. In this era, lime was already a building material widely used by the government and the private sector.

For example, Yu Qian, a famous minister in the mid-Ming Dynasty, once left a lime chant. The line "The fire burns as if it is idle" refers to the process of calcining limestone into quicklime.

Su Ze had an idea and asked: "Is the lime from this government-run mine for sale?"

Xiong Wu looked at Su Ze doubtfully and said: "Sell it, of course. The tribute and taxes from this official pit are all converted into silver and sent to the capital, so naturally it will be sold to outsiders."

Su Ze also felt that he had asked a stupid question. Lime is easily affected by moisture and would certainly not be transported long distances to the capital.

The silver that the officials dug into the warehouse must be converted into currency and handed over to the emperor's private treasury.

"Besides lime, are there any iron ore slag for sale?"

Xiong Wu replied: "Yes, there is a government-run iron smelting plant in Nanping County. There is a Dajian furnace for iron making. Every day there is a large amount of slag that no one wants."

"What about the plaster?"

"Gypsum? The pharmacies in the city should sell it, right?"

Su Ze was slightly disappointed, but it was not necessary to make that plaster.

If "that thing" could be found, Su Ze would be more confident in concentrating water, flushing sand, and building a stream.

Climbing a hilltop, Su Ze looked at Jianxi River. There was a U-shaped river turning area in front of him, and Su Ze was going to dig through it to build a reservoir.

In the future, some water conservancy and irrigation facilities can be built next to the reservoir, and dozens of acres of high-quality paddy fields can be reclaimed for Changningwei.

The outlet of the reservoir should narrow the river channel so that the water flow in the reservoir can flow faster and wash out the downstream river channel.

Su Ze was writing and drawing on the copied hydrographic map. This hydrographic map was completely different from the one in the ancestral hall. It was full of dense numbers.

What Su Ze held in his hand was not a writing brush, but an ink-soaked pen made of reed sticks.

This kind of pen is the favorite one for accountants and clerks. They have been dealing with writing for a long time. This kind of pen was created for long-term convenience of writing.

As a modern person, Su Ze naturally prefers this kind of ink-stained reed pen.

[Site survey, water conservancy skills experience +5, Lv2, 1/200]

Upgraded.

These days of surveying, mapping, planning and design, Su Ze's [water conservancy] skills have gained a lot of experience.

After reaching the second level, Su Ze picked up the hydrograph again, and this time he had new inspiration.

Su Ze modified a few more designs before rolling up the hydrographic map with satisfaction.

Xiong Wu stood behind Su Ze, feeling even more surprised than the people in Chang Ning Wei.

Water conservancy is not a subject accessible to ordinary people, although Xiong Wu could not understand what Su Ze drew on the hydrograph.

But he could tell that what Su Ze wrote was definitely something very powerful.

Xiong Wu already knew that the formation that defeated him was rehearsed by Su Ze. He was good at both civil and military skills. He even knew about weaving, salt production and water conservancy. What kind of monster was this?

Su Ze finally finalized the plan, and the next step was to prepare tools and materials, and start work when he came back from the county.

On the way back to Changning Guard, Xiong Wu approached Su Ze and whispered:

"Xiangong Su, Fujian is about to be in chaos. This is not a good time to repair the river."

Su Ze said calmly: "The deer king is still outside the sea and will not invade Fujian until the rainy season."

"I'm not talking about the sea, but the land."

Seeing Xiong Wu pointing to the north, Su Ze immediately understood what he meant. He reminded Su Ze to be wary of the rebellion of Jiangxi Luo Jiao!

Su Ze did not show any worried expression, but sneered and said:

"I have never told ordinary people in Changning Wei about Jiangxi Luo Jiao, let alone you. How did you know about it?"

I saw Xiong Wu put his hands together and opened them, made a handprint and said: "The red sun is over, Bai Yang will be lucky!"
