Hukou Waterfall, both sides have become a large construction site at this time.

Countless laborers are working here in full swing at this time.

Since inspecting the geographical environment here that day, Yang Yinuan knows that although the geographical environment here is good.

But if you want to build a dam here that is cut off at the waist, it is almost impossible with the engineering power of this era.

The height difference of 500 meters is really suitable for the construction of a large hydropower station.

But the problem is that this has to be a blue star with modern construction technology.

And on this planet, if you want to build a modern hydropower station, it is simply a fantasy.

After that day, Yang Yinuan also inspected the water situation in the upstream and downstream of the dammed lake.

Upstream, there is an Iron Mountain Range with an average altitude of three to four thousand meters.

Because it is located in the north, the climate is relatively cold, and there is frequent snowfall in winter, so those mountains are covered with snow all year round.

However, in the middle and upper parts of the mountain, there are still some geothermal resources.

As a result, it snowed on the mountain, but the snow on the mountain could not be saved.

Basically, there is snow only on the top of the mountain, and the snow melts soon after that.

Then follow the valley and go down the trend, while following the terrain trend.

Several rivers in the mountains converge on this platform, forming this dammed lake.

And because there are many rivers that converge, the water potential is also relatively turbulent.

If you want to stop the flow upstream and build a dam, it is simply impossible.

But if the upstream is not cut off, it is also impossible to build a dam here in the hukou.

Unless there is a large number of modern construction machinery.

Since the traditional method of building dams to generate electricity does not work, the small turbine generators brought by Yang Yinuan can just play a role.

He and Grande selected a few rivers with a large difference in terrain, and designed several trenches along the terrain on the sides of the rivers.

Finally, at the corners of the trenches, this small turbine generator is arranged.

This technology, which has only just been developed on Bluestar in recent years.

Ideal for some small cities to use electricity.

It doesn't need to be done in a big way, and it can be done with very little work.

Of course, even if it's a small amount of work, it's for the modern world.

If it is on the Falken planet, then at least several construction teams of hundreds of people will be required to work at the same time.

Of course, that was before, but this time Yang Yinuan came over, but he brought an excavator.

After all, every boy has a dream of Lan Xiang when he is a child, and Yang Yinuan was also very interested in this kind of large construction machinery when he was a child.

It's a pity that later, I didn't have the opportunity to read Lan Xiang.

However, he had a classmate in college, and there were several such construction machines at home at that time.

During the holidays, when he went to play with the same school, he also played around for a while.

It's not very good at fiddling, but at least it can be driven.

As soon as the excavator appeared, it stunned the local people at the scene.

In this world, can there be such a giant?

Although Yang Yinuan is not very good at fiddling, this thing is simply a big toy for Grande, who is proficient in construction machinery.

People can even play with armored vehicles, let alone such a small excavator like yours?

I drove the excavator and dug out the trench by the small river.

This efficiency was dumbfounded by the large group of native captives present.

The composition of the captives captured this time is very complicated.

Most of them are high-powered private armies, who themselves grew up in the North.

So for letting these people return to their hearts, Yang Yinuan doesn't worry about it at all.

In his opinion, it was only a matter of time.

But the other part, such as the iron canned soldiers in Qingshan City, and the wolf cavalry in Nuanzhou.

This made him less worried.

The tin cans in Qingshan City seem to be soaked out of medicine jars.

All of them are tall and strong, full of brute strength, and their tempers are also very irritable and unruly.

After capturing more than a thousand of these captives, these guys are going to fight every once in a while.

In the past half a month of hard work, dozens of people have died just from fighting.

Not only do they fight with others, but they also fight with their own people, anyway, it's like a cannon battle, it's really just a point.

As for the wolf cavalry in Nuanzhou, it is the complete opposite of these guys, although these guys look scary.

But his brain is very wooden, as if he can't ride a wolf to fight outdoors, and he doesn't look very good at anything else.

The captives gathered together, and during this time, there was some fun to watch.

The casualties were much higher than the last group of prisoners, and these three groups have always been unconvinced.

Of course, in front of the whips and bayonets of the defenders, they were obedient.

Because Grande is not used to them, in their own territory, they may be the uncle, the elite.

But in the city of a thousand mountains, they are captives.

If there is anyone who does not understand their status, they still want to challenge the rules of Thousand Mountains City.

It was very simple, the light one was fried meat with wattle strips, and the heavy one was directly pulled out and hung on the gallows.

So although there are a lot of unruly people in these guys, after more than half a month, those who have tempers have basically been worn out.

Recently, Grande has begun to break up the three groups of captives and reorganize them from a new group for labor reform.

Although there is still friction between these three groups, they get along much better than a few days ago.

And today, when these people saw Grande and Yang Yinuan, driving such a rumbling machine, rushing left and right on the ground.

In less than half an hour, when a trench 100 meters long, five meters wide, and two meters deep was dug in the ground, the captives were all stunned.

Especially those wolf cavalry who don't seem to have good brains, there are several guys at this time, kneeling directly on the ground.

At the two excavators, no matter how much they bowed, they muttered words like 'miracles'.

And Yang Yinuan, who was driving an excavator in the distance, and Grande, when they saw such a picture at this time, they laughed and said nothing.

After a period of such a labor camp, these captives may soon be converted to them!

This is the process that you want.

It is to let you constantly carry out some spiritual and mental transformation while working.

It's just that he didn't have a suitable "political commissar" at hand before, and he couldn't guide these people ideologically.

But now Yang Yinuan seems to have found a new way, and the people of this world are very admiring divine power.

When they are confronted with something incomprehensible, they always blame it on miracles.

And this gave him a good 'brainwashing program'......

As long as they continue to show their divine power in front of these guys, then they will naturally have cowardly thoughts.

Once they're scared, their hard shell is gone...
