At the beginning, his wife came to him, and he became rich by selling kidney treasures.

In the afternoon, under the instigation of Ren Hao, officials of all ranks in Qiantang County came together to arrange the people to dredge the flood in an orderly manner.

With the food and silver brought by Ren Hao, the people who originally could not even fill their stomachs were finally able to eat two meals a day.

Under Ren Hao's regulations, all the strong and capable people were pulled out to work, and half of them went upstream to build a dam to block part of the water flow.

There were blueprints of the dam made by Ren Hao and the craftsmen. Based on his experience in his previous life, Ren Hao made a layered decreasing dam.

The principle is very simple. It is to accumulate dams multiple times in the same river channel to slow down the speed of water flow. Although the total amount of water remains unchanged, the speed is reduced by more than one third.

For example, in the previous life there was a place called Shiyan, which got its name from this.

Even if you haven't eaten pork, you have seen pigs run. Just a general understanding of it has allowed Ren Hao to stand at the forefront of this world.

The other half of the strong ones are responsible for clearing the canals downstream.

Because of the flood, the river channel downstream was blocked. For a time, the water here was difficult to drain in a short period of time. Moreover, as more and more dead branches and other debris washed away by the flood accumulated, an unbreakable natural dam would slowly be formed. By then, it would be much more dangerous to clean it up.

Therefore, Ren Hao’s first request to these people was to dredge the river as soon as possible.

After dredging the river, it is necessary to dig canals, build stone channels for water diversion and repair the river.

This is a huge project.

Ren Hao’s requirement is that the project must be completed within half a month.

In this way, we can block the upper part and drain the lower part, and we can truly clear the flood. Moreover, with a dam upstream, even if there is a flood in the future, we can control the water flow through sluices, and truly control the water.

These were some experiences that Ren Hao had occasionally seen in his previous life. He had no idea how to build or cast them, but as a leader, he only needed to control the direction, and someone else would naturally do the rest.

The strong men had been arranged, and the remaining middle-aged women were not idle either. Ren Hao asked Hongyao to take them to make a large number of tents, net bags and other items using the purchased cloth.

These things can be used to provide tools for people traveling upstream and downstream.

Some older women were assigned to cook, and the children were assigned to collect firewood.

Only some very young babies and children, and some really old people, can stay in the camp, and their only responsibility is to eat and stay alive.

Ren Hao himself was not idle either. He either went upstream to direct the construction of the dam, or used his spare time to make some tools.

After a few days, the most successful product Ren Hao made was a right-angled baffle.

When this baffle is placed in a rapid water flow, it will cling firmly to the riverbed due to the interaction of forces, and the upper part can block the violent water flow.

With this tool, the construction of the dam became much easier.

Everyone couldn't help but marvel at it.

Even Li Tang was in awe and praised Ren Hao as a god who had descended to earth.

Time passed slowly.

Half a month passed by in a flash.

On the last day of half a month, when Ren Hao was gathering merchants from all over the country who had gradually arrived, Li Tang came in with an excited look on his face.

"Sir! Happy event! A great happy event!"

"The dam has been completed and the flood has gradually receded!" Li Tang's voice rang out.

Ren Hao was shocked and quickly led his men to a high place.

Looking down, the flood has receded by more than half.

Black soil has been exposed in many places, and houses have been destroyed by floods.

Looking at the mess below, Ren Hao was excited.

"Okay! Well done!"

The biggest challenge in this disaster relief is water control. As long as the water is controlled, the remaining buildings will be easy.

Arriving at the temporary forum, Ren Hao glanced at the thousands of merchants from all over the place and said, "Everyone, the time has come."

"Next, it's your turn to take the stage."

Ren Hao's voice sounded slowly, causing the businessmen below to nod and bow in agreement.

The scenes of killings that Ren Hao had started in various places still left many people with a shadow in their hearts, for fear that they would be displeased by this living devil and then be killed.

"Here I have a plan map and a plan book."

"There are hundreds of different projects from residential houses, shopping malls, streets, government offices, schools, etc. I hope everyone will actively participate and sign up."

"Qiantang County is currently in a state of disrepair. After everyone has paid, although the right to use the land is not yours, you have the right to benefit from it. The people here live in the houses you funded and built, so they have to pay you the corresponding fees."

"In a few years, your costs will be recovered and you will make more money."

"With this official's guarantee, you will not lose money, and places like shopping malls will make more money."

"After paying fees to you for more than fifty years, private houses will belong to the residents, and public places such as shopping malls will belong to the court."

"As for the specific projects and details, please check them out for yourself."

“If anyone feels bad about it, they can quit.”

Ren Hao finished these words calmly.

The group of merchants below hurriedly smiled and said, "Your Excellency is right. We must follow your steps and do everything just like you."

A smile suddenly appeared on Ren Hao's face.

Everyone was complaining in their hearts, quit? I'm afraid that as soon as they leave, they will be sent to see the King of Hell by you, a dog official!

No one will believe your words!

However, these merchants have no soldiers and no power. Even if they have power, they are not enough in front of Ren Hao, the imperial envoy who has the power to do whatever he wants.

In other words, death is in vain.

People under the eaves have to bow their heads!

Following Ren Hao's arrangement and coordination, the merchants put in their best efforts and after receiving the projects, they immediately paid money to find the common people to do the work.

These men who had just lost their homes responded when they saw there was work to do and money to be made.

So there is no shortage of manpower.

In addition to the craftsmen brought from all over the place, small construction teams emerged like mushrooms after a rain, led by the craftsmen and assisted by the common people.

The next day, the flood gradually receded to the original river channel, and all parts of Qiantang County were exposed.

However, after being soaked in floods for two months, the original land appeared very muddy, and there was water accumulation in some places.

In order to make things easier for everyone, Ren Hao created a tool for walking on mud called "mud horse" that he had seen in Douyin in his previous life.

This simple tool is easy to make, and Ren Hao made it without much effort. He then asked the carpenters to produce it as quickly as possible and handed it over to the more than 1,000 construction teams below for use.
