Years later, the weather gradually warmed up.

The frozen river is also gradually thawing.

The tribesmen found that after the thaw of the river, there was a gap of more than three meters between the ice and the water layer.

That is, in this winter, the water level of the big river dropped by more than three meters.

At this time of year, it was a rainy time.

And the tribesmen are picking sweet fruits in such weather and waiting for the summer flood.

After the summer fishing season has passed, water is diverted to cultivate.

But this year, not only has there not been a single rain, but even the big river is about to dry up.

As for the inside of the field, it has long been cracked into pieces.

For this situation, the clansmen are somewhat unmastered.

Even if such land can be cultivated, this year's harvest will be at least halved compared to previous years.

Moreover, if the drought continues into the summer and there is no rain, it is normal for crops to be harvested.

Facing the panicked voices of the clansmen, Wang Hao told them not to worry, they should continue to cultivate this year, and let him solve the problem of water sources.

Although the flow of water in the big river has been reduced by more than half, it has only made the river water lower than the canal, and it is impossible to irrigate the fields.

Two thousand waterwheels were stationed almost twenty-four hours a day at all convenient places along the great rivers in China.

The roar of the pumps is almost incessant along the river.

The little animals that came to the river to drink were frightened far away.

The two thousand waterwheels, 1,000 of them, were used to irrigate the farmland of the tribe.

Five hundred vehicles are used for construction and industrial water, and another 500 vehicles are used by Wang Hao for emergency and watering some raw material forests.

In addition to these 2,000 water trucks, Wang Hao also prepared ten well-drilling teams.

It's just that although the drilling machine is simple to use, there are too many aspects that need to be taken care of if you want to drill a deep well.

Not to mention anything else, how to prevent the collapse of deep wells requires a long time of training for the personnel of these well drilling teams.

Therefore, these well-drilling teams will not be useful in a short period of time.

Although there is still water flowing in the big river, Wang Hao knows that it will not be long before the river will definitely stop flowing.

Therefore, he planned to wait until the flow of the river was reduced to a certain extent, and then he would cut off the flow in the middle of the river, and at that time, all the upstream river water would gather in the place where the flow was cut off, forming a small lake, so that at least Huaxia could hold on for a while without using the reserve water.

Because the natural environment of the Great Wilderness is all controlled by man.

Therefore, for thousands of years, the Great Wilderness has always been smooth.

Therefore, the vast majority of the plants of the Great Wilderness do not have the habit of digging deep into the soil.

Anyway, the surface of the ground has a lot of nutrients and water for them to grow, so why bother to dig deep into the soil.

And now, when the drought comes, the plants that grow in the wild without water sources are out of luck.

The beginning of spring should have been the growth of all things, purple and red, and as far as the eye could see, it was green.

But now, the weeds are withered and yellow, and they are all the dead grass left over from last year.

Occasionally, a weed or two just popped up and was quickly eaten by hungry rabbits and deer.

One side of the water and soil to support the other side.

On the earth, because plants grow slowly, even if there are animals in the wild, the number of animals is scarce compared to the wilderness.

But in the Great Wilderness, all the plants can be expressed in terms of madness.

Therefore, it is completely possible to feed a large number of herbivores, so there are so many creatures in the Great Wilderness.

But now, a major drought has slowed the growth rate of plants to about the same level as on Earth.

The huge herd could not find enough food to eat, and they were hungry and bone-to-skin.

Now, as long as it's green, they want to take a bite.

It stands to reason that it has only been less than a year since it rained, even if plants such as weeds have been seriously impressed.

But the impact of big trees is always much lower.

But in fact, the situation of the big tree is not good.

Although their roots are relatively deep, for the time being, they can still hold on.

However, there was not a single snow last winter, and the eggs that had been hiding in the dirt for the winter survived in large numbers.

By the beginning of spring, they hatch into adults, causing serious damage to trees in the wild.

In a large forest like the Black Forest, where there are enough birds and small creatures to regulate, the pest does not appear too severe.

But in some small forest forests, often overnight, more than eighty percent of the leaves will be eaten.

The magnitude of the disaster is worse than the locust plague on the earth.

Fortunately, the oak trees, diesel trees and other plants planted by Wang Hao were prevented in advance and sprayed with pesticides.

And the insects of the Great Wilderness have basically zero resistance to artificial agents, so they have not been affected, but in other places, it is already miserable.

These disasters were seen by Wang Hao, but for ordinary clansmen, they did not have much impact.

Let the grass wither and the yellow trees will wither and yellow, and if there is an insect plague or something, just sprinkle some medicine on the place where you live.

As for the problem of water sources, the patriarch said that he would solve it, and what else was he worried about.

The only change for them in this drought is that they have changed from going to small rivers and streams to getting water from waterwheels.

Compared with the hassle of drilling deep wells, it is much easier to train an electrician who is simply used to install the wiring.

Two hundred electricians, after ten days of training, are already proficient in wires.

These electricians connect the lines to the transformer voltages, and then pull the wires to the various population centers.

They rely on the theoretical knowledge they have learned to practice, and then summarize the experience in practice, and pass on this experience to the apprentices who follow them.

After their apprentices have learned, they will be discharged, and at that time, these apprentices who have just graduated from the apprenticeship, no one will take a few apprentices to practice.

Although there are now more than 400,000 people in China, there are only 200 electricians.

But Wang Hao believes that in a few months, this number will increase dozens of times.

As the saying goes, it's hard to get started.

When several villages around Hwaseong, with the help of these electricians, installed several headlights in the village, bringing electric light to their nights.

With Hwaseong as the center, the light spread rapidly to all directions.

When the weather becomes hot and China enters the middle of summer, at least half of the villages in the whole of China can be lit up at night.

Although the lamps are not enough to be popularized to every household, Wang Hao believes that when every Chinese clansman can use the lamps normally, it will not be too far away.
