In order to ensure the strength of the embankment, these Huaxia contractors carried out the construction of the embankment in layers according to the requirements of the Ministry of State-owned Assets Supervision and Administration Commission.

The first layer of earth and rock was filled slightly above the water level, and then the coming-and-coming carts and people kept crushing the freshly paved embankment.

After all the embankments are formed, the second layer of soil and rock is filled again, and the thickness of the second layer of soil and rock is only increased by about 30 centimeters, which can ensure that the inside of the embankment is not prone to cavities and loose soil.

With the support of abundant human resources and far more advanced excavation and transportation tools than the world, an earth-rock embankment three meters above the water level was built when the artificial river connecting the Gangneung moat and the Yangtze River channel was fully connected.

The middle dam divides the entire enclosed basin into two areas, forming two separate large ponds.

Those micro-tillage machines sent by Huaxia Kingdom also entered the field, but fortunately, Li Yan was on the scene when he went down to the pond, otherwise these micro-tillers might have been directly sent back to the real world for overhaul.

Because the mud in these swamps for many years didn't know how thick it was, even the crawler-type micro-tiller was almost stuck in it and couldn't move, and finally Li Yan used the shared space to transfer the micro-tiller trapped in the silt.

It seems that the idea of directly transforming these mizusawa into paddy fields is too simple.

After the problem was fed back to the Ministry of State-owned Assets Supervision and Administration Commission, after discussion, it was decided to clean up some of the silt in these waters.

However, there was a fierce debate about how to clean up the silt, and it was decided to send the silt from the ponds to the higher ground in the surrounding areas for farming.

In this world, due to the lack of advanced irrigation machinery in Huaxia, the quality of the fields is mainly based on whether the water is convenient.

Therefore, those small hills on higher ground will hardly be developed by indigenous people, because the developed fields will hardly have a good harvest in the case of lack of water, and if God does not help, it is normal for the grain to be unharvested.

However, this made it convenient for Wei Minsheng, and according to his arrangement, all the slightly higher places around Shuize were reclaimed.

The weeds on these hills are quickly cleared, and the fresh weeds are mixed with starter culture and sent directly to the digester to produce biogas, while the dry weeds are slightly crushed and gasified, and the straw gas produced is used by an explosive engine to generate electricity to power nearby construction sites.

When the aborigines saw that these Chinese people had arranged for them to reclaim these small hills, some honest people couldn't help but shake their heads, these fields that are not suitable for cultivation are reclaimed, and the harvest of one or two years may not be enough to cover their expenses for cultivating the fields.

But these Huaxia kingdoms were unmoved by their kind reminders, and still built these small hills with small slopes into a circle of terraces in their own way.

From the sky, it looks like the contour lines on those engineering maps, drawing all the hills around Mizusawa.

Just when the aborigines were about to see these Chinese jokes, they found that some other Chinese people had brought some strange things in the kind of cars with three wheels.

Those pipes of almost the same size and thickness are made of no material at all, they are as soft as silk threads, but they are impermeable, and the most amazing thing is that there is no seam on the whole tube.

I saw that those Chinese people had erected a shelf by the water, and a pipe as thick as an arm was attached to the tricycle on the shelf.

There was another long pipe behind the tricycle, the end of which was submerged in the moat, and a tail with the thickness of a black finger connected in the direction of the "Thor drum".

Just when everyone didn't know what they were doing, a Chinese Chinese pressed a few times on the tricycle, and a water dragon three feet long suddenly erupted from the water pipe on the shelf.

Under the manipulation of the Huaxia people next to him, the water dragon fiercely plunged into the mud in the water, and then flooded with streams of sewage around it.

The sewage slowly converged to the low-lying areas in the water, and the Chinese people also manipulated the water dragon to slowly wash those low-lying areas.

A pipe was dropped on another identical tricycle next to it, and it was submerged in the sewage from these low-lying areas, and soon it was impossible to see a cage on top of the mouth.

The water pipe on the other side of the tricycle goes directly to the "terraces" on the highest part of the hills.

Under the operation of another Chinese national, the sewage was pumped directly into the hill by the sewage pump on the tricycle.

And the Chinese people who contracted the construction of these hill terraces nervously observed the flow of this sewage.

Because the area of paddy fields they end up creating is tied to the remuneration they deserve, any embankment that is washed away is a serious loss.

Therefore, they had to carefully inspect these embankments when irrigating the terraces, and arrange for manpower to repair the leaks in time.

At the same time, they also had to find a suitable place to excavate the outfall after the terraces were irrigated, firstly, to prevent the overflow embankment from breaking the embankment, and secondly, to allow the sewage to flow smoothly to the next terraced fields, so as to ensure that the terraced fields above the entire hill became paddy fields.

There were more than 20 such tricycles, and it didn't take long for them to rush out of one pond after another, and in some close proximity, multiple ponds even merged together to form a larger pond.

Due to the presence of these large ponds, the water dragons around the embankment have less and less effect on the silt washing, and even the aborigines who watched the bustle next to them can see that the power of these water dragons is not as strong as before.
