In the wilderness for thousands of years, cities with a population of three and a half million have been as rare as a few people, and as for large cities with a population of one million, they have hardly appeared and are unlikely to appear.

Being oppressed and cleared by the Divine Domain is one of the main reasons.

But that's not the root cause!

Because of the limited resources for survival in the wilderness, the single way to obtain food, and the extreme scarcity of water sources, it is difficult to create a large settlement that can meet the needs of tens of millions of people.

Every settlement has limited resources to survive.

The upper limit of survival resources determines the upper limit of the population.

When the population exceeds the maximum that the region can accommodate, the competition for survival becomes more brutal and miserable, and it is not surprising that this situation is killing people and drinking blood. The loser either dies or leaves, and it is precisely because of the natural mechanism of the elimination of the last position that the scale is always firmly limited.

Yunying's current approach is the opposite.

He broke the scattered form of the wilderness, and he planned to build a large wilderness main city, unify the language and currency, and establish a national civilization and army.

In the future, the population of the main city will be at least one million or more, and may even reach several million.

However, the scale of the resources of the oasis can only support more than 100,000 people, and if the population grows to one million, I am afraid that it will face a very severe challenge, let alone a few million? That is simply impossible! Within a few years, it will be squeezed dry and turned into a desert.

Now the sense of crisis is very strong.

Because at the current rate of population growth, water may only support two weeks' consumption, and food can only last for a month at most, if a good response plan cannot be devoured, the establishment of the main city of the Southern Wilderness will have to be suspended.

The other side of the flower put forward the idea of opening up sources and reducing expenditure.

On the one hand, the population growth rate should be controlled, and on the other hand, the water and food supply channels should be increased.

As for the means of implementation, it is natural to limit the size of the new population per day, so that the population growth can be controlled and managed, and at the same time to explore the oases and nearby groundwater resources in large quantities, open water transport routes in the wilderness, collect water from the surrounding areas, and collect and transport them back with tankers.

This is indeed a rational way to deal with it.

However, it can only be relieved for a while, and cannot solve the problem fundamentally.

Moreover, how could the countless wilderness people turn them away on their way to the main city? The wilderness environment was so treacherous that people would die every day of delay, which was too great a blow to the enthusiasm of the latecomers.

The method of transporting water by water trucks is also not very reliable!

NSFOCUS does not have many water tankers, and if one is damaged, there is one less.

The tanker truck drove into the wilderness, and it was definitely walking fat, and all the bandits and sweepers would be interested in it, because the tank was filled with either oil or water, whatever it was, it was enough to arouse the greedy nature of the bandits.

As for digging wells in search of groundwater?

Yun Ying still felt a little unreliable.

The deterioration of the entire wilderness environment did not occur overnight, but slowly transformed over a period of more than a thousand years, and now, except for a few miraculous places like the oasis, it is difficult to easily find water sources in the yellow leaves.

There is another way,

If it really doesn't work.

Then it's up to Yunying to take action personally!

Cloud Eagle uses the ability of spatial transportation to carry water from the Otherworld.

This is a solution, but it can only be an emergency, not for a long time, after all, the symptoms are not cured, Yun Ying, as the supreme leader of the Green Alliance, how can he be a porter all day long? Not to mention that even if Yun Ying is very strong, the strength of one person cannot serve millions of people at the same time after all.

It doesn't work either.

That won't work either.

The main city of the Southern Wilderness is full of difficulties.

Yunying ended the meeting early and walked the Oasis City trail, just wanting to think quietly alone.

At this time, the cry of the little monster bird suddenly reached the ears: "Squeak, squeak!"

How did that little guy end up here?

Yun Ying didn't carry the little monster bird with him recently, and the little monster bird either hunted by himself in the other world, or was handed over to Shui Lan and other children to assist in cultivation. Don't look at this little monster bird is not a high-level divine beast, he has followed Yunying for all these years. Now he has grown into a strong guy.

Enough to deal with an ordinary high-level demon hunter alone.

With the help of the Yunying Spirit, a master like Beichen Xi is not his opponent.

The essence of the little monster bird is a special weapon, and the weapon itself is certainly strong and weak, but more important is the person who uses the weapon.

When Cloud Eagle walked over.

The little monster bird follows a girl.

The girl looked to be in her teens, dressed in the special leather armor of a demon hunter's apprentice and with an exorcist stick stuck in her waist, carrying a large bucket into a wasteland, an open space in the middle of an oasis that had never been exploited.

What is this little girl doing here?

After Shui Lan walked into the wasteland, he put the bucket on the ground, and immediately took out a glove and put it on, judging from the material of this glove and the pattern on it, this glove should be a magic weapon, and Shui Lan started it immediately after putting on the magic weapon.

The water molecules in the surrounding air all gather in the palm of your hand, forming a small trickle, which flows like a faucet into the bucket you brought.

A quarter of an hour or so.

Finally filled a bucket with water.

She poured all the water in the bucket in the middle of the clearing, let it flow into the barren sand, and began to collect the water, filling the bucket again, and repeating the action over and over again.

The little monster bird sensed the appearance of the cloud eagle.

It immediately flapped its wings and squeaked.

"Ah, old ...... Teacher, why are you here?"

The little girl found that Yun Ying had been secretly watching her not far away, as if her little secret had been discovered, and she immediately became a little at a loss.

Yun Ying was wearing black clothes, which set off an increasingly mysterious atmosphere, he walked slowly with his hands behind his back, when he looked at the wasteland that was wet with water, and then looked at the tired and panting little girl in front of him, only to see that there were constantly small beads of sweat, along the gradual chin, clattering and falling to the ground.

"What are you doing here?"

The little girl scratched her head embarrassedly: "I'm trying to save this land." ”

When Yun Ying heard this, he couldn't help but show surprise: "What?

The little girl nodded very seriously and said, "The lecturer of the Oasis Academy said that the land will be barren because of the lack of water, and if the land can be kept water, the desert will be re-greened and revived sooner or later...... So I borrowed this artifact to do expendable training and try to awaken the Oasis Wasteland. ”

Actually, for Aqua Blue.

This in itself is an expendable exercise.

The so-called consumption exercise is the process of recovering from the continuous exhaustion of mental power.

Yun Ying didn't pay much attention to Shui Lan's words at first, even if this method was really effective, how could it be possible to revive the entire desert? The water loss and evaporation of the earth are too great, and it would be naïve to think that the water created is like reviving the land.

But hear the last.

A flash of light flashed in Yun Ying's mind.

Shui Lan's words seemed to inspire him somewhat.

That's right, why didn't he think of this method just now?

The oasis is short of food and water, and the first thing Yun Ying thinks of is a scientific solution, so he will consult the other side of the flower, but the problem is that Yun Ying himself is not such a scientific person, or a person who cannot be explained by human science, why doesn't he solve it through another way?

There are Demon Hunters in the Green Alliance.

NSFOCUS can also materialize spirits to form spirit beads.

There are some things that are difficult to do with ordinary science, and if you skillfully use demon hunters and gods and demons technology, then you may be able to turn decay into magic.

For example, how difficult is it to collect water in the wilderness using scientific methods?

If Yun Ying can invent and create a magic weapon that can generate water, just like this glove in Shui Lan's hand, everyone with spiritual power can make water, and the magic weapon can turn any substance into water, will NSFOCUS still be so short of water?

As long as NSFOCUS continues to train demon hunters, it will never run out of water!

In addition, the use of demon hunters is also reflected in all aspects, magic weapons are tools created by gods and demons, although human beings do not know what its principle is, but theoretically human technology can not do or difficult to do, all can be achieved through these tools that turn decay into magic.

"Teacher, what's wrong with you?"

Shui Lan looked at the teacher with a surprised face.

Yun Ying gently stretched out a hand, I am afraid that the woman will also be jealous when she sees the teacher's hand, just like the warm white jade carved out, so that people can not see the slightest trace of pores.

Almost at the same time.

The aqua blue can be clearly felt.

The surrounding air, as well as all the substance, was enveloped by a force.

The loess quickly swelled up and became moist and fertile, and all the air molecules were radically changed, and in a matter of seconds countless water molecules gathered together, and finally a light rain fell, making the whole wasteland damp and full of the smell of earth.

Is this the power of a teacher?

Actually, there is nothing in this scene itself!

Shui Lan believes that many powerful demon hunters can do it as long as they hold the corresponding artifact.

But the teacher didn't use the artifact at all!

Although the teacher had been able to create or change matter with spirit more than a year earlier, it seems that his ability has become stronger than it was then.

Cloud Eagle withdrew his hand.

The surroundings are completely new!

Although the mutant bacteria have a strong ability to reproduce, under the same conditions, the growth rate and efficiency from the sandy soil are certainly not as good as such modified fertile soil, if the cloud eagle can green a wider range of deserts, then the area of the oasis will expand in a short time.

Oases are expanding, resources are increasing, and only a permanent increase in population ceilings is the real cure...... But then again, while you're right, it's not that simple.

First of all, this kind of ability to break away from the artifact and create matter out of thin air, or change matter, I am afraid that Yun Ying alone has it after the whole world, and the power of one person is very limited after all, and it is reluctant to change a small piece of wasteland, if he is allowed to change the entire desert, it is impossible.

Secondly, even after the completion of the transformation.

And in what way should it be maintained?

After all, the environment has deteriorated so much in this era that even if the land can be greened, if it is not protected, sooner or later it will be re-engulfed by the wilderness.

Yun Ying kept generating new ideas in his heart.
