In other words, the world is completely different from what it used to be?!

Without the sea regulating the climate and the huge clouds of water vapor, it is impossible to transport water to other places through the action of the wind to form rainfall.

No wonder, no matter how windy and cold it is, there has never been a drop of rain.

All rivers have been turned into groundwater, and all irrigation can only be done by opening up underground rivers.

This shows how rare it is to see a waterhole that is still exposed to the ground in the Qunfang Valley.

Of course, it may also be because the terrain is already very low, and there is something where the underground river is weak, so it is revealed.

Xiao Z followed this major clue newly obtained by Qin Gu and deduced more information.

Xiao Z: "According to my analysis, the pattern of this small world is 28 points of land and sea, that is, only 20% of the surface of the planet is land. The rapid development of human civilization soon took over, and exploited the 20 percent of the resources on the land to the limit, so that the natural environment could no longer function normally, and could not produce enough energy to maintain its equilibrium. So the planet made an adjustment at the last limit......"

Qin Gu responded with a hint of self-deprecation and sadness: "So...... Since 20 percent of the land is no longer enough for human beings, 80 percent of the remaining area has also become land?!"

However, according to Xiao Z's analysis, perhaps in that energy depletion and earth-shaking change, it is not necessarily that the ocean on the original planet has become land.

Instead, under some force, it fused with other similar small fragments of space, thus turning all the places that were originally covered by water into land.

In other words, the entire planet is now surrounded by a layer of crust, and there are still large areas of water, underground rivers, and so on beneath the crust.

This explains why, even in such a dry wasteland, water can be obtained more than 100 meters underground.

Qin Gu thought of a question: since there is a lot of water under this layer of the earth's crust, then ...... Can we use a huge project to chisel open this layer of crust on the surface and restore the original pattern of water and land again?

Xiao Z responded: This ...... As far as I can deduce now, this... Maybe it can be done in a small area, but if it is a large area of land and water transformation...... I'm afraid it will be another apocalyptic catastrophe on this planet.

Qin Gu was a little puzzled: why would it be another apocalyptic catastrophe to divert groundwater to the surface?

Xiao Z: According to my data analysis, 80% of the newly born land on this planet is floating on the water. Well, it's like a huge ship floating on the water, and if you disrupt the pressure balance somewhere, it can cause the entire plate to collapse.

Qin Gu understood what Xiao Z meant, and was shocked.

Could it be that the only way out for them now is to survive among the living races?!

Little Z: Of course, whether a planet is stable or not determines whether it has enough energy to maintain balance.

Whatever the resource, overexploitation will upset the original balance, and once the load limit of the planet is exceeded, then she will make a self-adjustment and repair.

In fact, for the planet itself, this kind of self-adjustment and repair is like us humans turning over while sleeping, but for the life parasitic on this planet, it is a catastrophe.

Qin Gu thought for a moment and said, "What you mean is that as long as this planet produces more energy, it will be able to maintain balance and even restore its former glory." ”

Little Z: That's pretty much what it means.

After some communication with Xiao Z, Qin Gu had a feeling of empowerment.

The veil of the task that I had been thinking had been obscured in front of me was lifted all at once.

She had been struggling with how to conquer this task, and now she knew that it was not limited to one person, one village, but ...... Do your best to bring the planet back to life again.

As for how to implement it...... vegetation to make the planet back covered with vegetation.

The plant's strong root system absorbs water from the soil and even creates some kind of connection with the underground water source under the life force.

The water evaporates into the air, and when it reaches a certain level, rain is formed by the action of wind and clouds. Transporting water vapor from one place to another.

Of course, she couldn't make this barren and harsh planet full of greenery on her own, only people, human settlements.

Whether it's the current Wind Fort or the former Wulizhuang, there is significantly more vegetation in their surrounding area than in other places.

This is because human beings are aware of the importance of planting, and after meeting the needs of survival, they deliberately expand the scope of green plants.

Qingu probably understands why humans can stand out from the crowd of creatures that seem to be more powerful than humans: because in addition to the super destructive power shared by all living beings under self-reproduction and expansion, human beings also have even more powerful than destructive power-building ability.

That's right, even if the cunning hyena pack, the tough tiger and lion pack, and even the earth-armored lizards that occupy the right time and place and are very powerful in their own right, they only show their destructive ability like the three-light policy, and the rest is still a wilderness, still a long stretch of yellow sand.

Therefore, in the end, only humans can save this mess.

The current mission is to help the human settlement, just as it did to help the former Wulizhuang.

After having a clear direction, Qin Gu felt that his whole person was full of energy.

............

Three days later, the friends of Qunfang Valley finished trading in Wind Castle and prepared to go back with a large number of supplies.

Qin Gu said that she would not go back for the time being, and wanted to stay in Wind Castle to see more. Qunfang Valley has survived the catastrophe, and all that remains is to work hard to manage your life.

In fact, everyone doesn't understand much about the decision of Qingu, after all, the conditions in Qunfang Valley are so good now, there is no strong wind and sand, there is water, and the climate is better than outside.

But she had to stay outside...... That's it, everyone persuaded her when she was in the valley before, but she insisted on coming out.

Now that Qin Gu insisted again, they had nothing to persuade them, they only said that no matter what she decided, they would support her.

Ask her if she has anything she needs, and if she has anything, she immediately contact the people in her hometown.

The next step is to establish a fixed trading point in the Wind Castle, sell the "local products" of the Wind Castle to the Wind Castle, and it is also convenient to buy the things that Qunfang Valley needs at any time.

If you have anything in the future, please feel free to contact the person in charge of Wind Castle.
