The experiment is over, but it can only be regarded as half the success, because it only verifies that the seeds can mature with auxin ripening, but whether they can grow naturally still needs time to verify, and the time it takes for the crop to grow in the outside world can also be measured.

At the end of the experiment, Li Yi's matter at hand was over.

Rao's life was calm again, but because the Reaper Mercenary Group and the Qingli Mercenary Group had established residences successively, the population pressure on the base had plummeted, and now the valley outside the city was not as overcrowded as it was when Li Yi first came.

Except for a few slightly larger groups and organizations that still have troops, other small groups and small retail investors have already moved into the city, as for why, of course, their leaders can't let go of the power in their hands. After all, after entering the city, you have to accept the jurisdiction.

And if something like the beast tide happens again, they also have to take responsibility, but outside the city, it's different, that is, they do it with their hearts, and if they don't do it, they will condemn it at most.

At present, there are four safe places in Rao City, but relatively speaking, only the base is here to refuse. And Wei Changfeng also developed, first of all, the vacated land, which he asked people to reclaim, seemed to be ready to plant crops.

However, these must be far from enough to satisfy the people of the entire base, so he also asked people to open up mountains and expand the soil, and it seems that he is preparing to build terraces, but ah, even if all three mountains are reclaimed, it will not be enough for the people of the base to eat.

Of course, the people at the base did not stop searching Rao City for a day, even if it has been so long, the things in Rao City have still not been scavenged, this is not the central area, like the central area, it is an area that no one has reached.

As for the expiration date or something, it doesn't matter if it's hungry.

……

On this day, Li Yi came to the base.

I handed over a bag of rosemary seeds to Cold Frost, and now the rudiments of the dwelling place have almost been formed, although there are not many houses, but everyone will not be squeezed into the cold, and as the construction continues, everyone will always live in the house.

Therefore, since the prototype has been formed, it is time to plant rosemary, once a rosemary is planted 50 meters below the rocky hill, then the rocky hill can be said to be an absolutely safe place.

Leng Hanshuang also knew what this bag of seeds meant, so he held it in his hand very carefully - it was about the safety of the entire team.

"Li Yi, there are still a few very critical things that you need to solve." Cold Frost went on to talk about the problems he had recently discovered.

"What's the matter?" Li Yi generally doesn't live in Chaoshigang, so the matter here is still handled by the leader of the second middle school class, although Li Yi is the leader, but it is more spiritual, and it is only about some major things, or things that they can't handle, they will seek solutions from Li Yi.

"The first is the problem of water sources, we are located in a high place, and we are on a rocky hill, before I asked people to prepare to dig a well, but I found that the ground is full of big stones, and it is very difficult to hit!" Cold Frost said.

There are boulders that really make it more difficult to dig wells, and the rocky hills are higher than the altitude, thirty or forty meters from the ground, which has to be drilled into the ground, and there is no water to see without 50 meters.

"Where did we get the water before?" Li Yi asked.

"In the beginning, we used the mineral water we brought, and at that time we started looking around for a water source, and then we found one!" Say it coldly.

At this time, Liu Tao interconnected, because it was him and Wang Yang who liked to go out: "The water source we found is a village about 20 kilometers away from us, and every household in the village has a well, where does our water come from!" Our brothers can bring back two buckets of water each time, but it's a lot of trouble! ”

"But there is a river that flows through that village, but the water is very unclean, and the people in that village seem to use that river as a garbage dump, and they throw all kinds of garbage there, and the water smells very bad." Wang Yang answered again and continued:

"We also searched the upper reaches of the river, looking for more than ten kilometers, although the water quality has improved somewhat, but it still does not meet the clean standard, and that direction is getting farther and farther away from us."

Li Yi nodded, somewhat understanding. At the moment, although the water problem is not a big problem, because it can still transport water from a village 20 kilometers away, it is very troublesome and not much.

However, Li Yi didn't think this was a problem, because he had devourers! The Devourer can completely solve this problem, didn't Cold Frost say that he wanted to dig a well in the rocky hill before? It may be difficult for a human to dig a well up to 50 meters deep, but the Devourer can.

It's just that it's so deep, how to get the water up is a problem, and if the well made by the Devourer is not strong, it is also a question whether it will collapse.

"Frost, take me to see the place where the well was dug before!" Li Yi was ready to give it a try.

Soon everyone came to a place, Li Yi didn't pay attention to it before, it turned out that this place was on the edge of the "canteen", the so-called canteen, which is a place for cooking and eating in a living place built by cold frost, a hut, plus a very large shed, this well is on the edge of the hut.

Li Yi took a look at the well that had not been dug halfway, it was about ten meters deep, but the diameter of the well was 4 meters, this was definitely a big well, and Leng Hanshuang was originally going to use this well to feed everyone in the place where he lived, but unfortunately it was blocked by a boulder.

Li Yi is ready to give the Devourer a try!

Taking out the Devourer from the system backpack, this is the first time Li Yi has taken it out, of course, Li Yi has a total of 4 Devourers.

A clump of aquatic plants suddenly appeared in Li Yi's hand, Li Yi looked at this clump of aquatic weeds, and couldn't figure out how it would be called a devourer, did it have a mouth?

However, it turned out that this clump of aquatic plants was the Devourer, because after taking it out, Li Yi could feel its existence in his mind, as if it was still waiting for his own orders.

"Go, expand the diameter of this well to five meters!" Li Yi pointed with his other hand and commanded.

Then I saw the devourer in Li Yi's hand flashing away, and the speed was so fast that people couldn't catch it, and then everyone saw that the water weeds were adsorbed on the wall along the well, and then everyone saw that the wall was sinking down at a pitiful "slow" speed with the naked eye.

As the minutes passed, no one walked away, and even more and more people came to watch, and then saw that the walls that had been "gnawed" by the devourers were smooth and shiny, not sand at all, but like glass!

Soon, the five meters that Li Yi asked for were done by the Devourer, and this time, it was almost half an hour. At this speed, you can reach a depth of 50 meters in almost two!

However, Li Yi was very puzzled, could the walls that had been devoured by the Devourers seep water?

As if hearing Li Yi's doubts, the devourer immediately "gnawed" in one place again, and then this piece turned out to be different from other places, this piece was like gauze.

"Okay, that's it!" Li Yi was very satisfied with the function of the Devourer, and immediately took out another Devourer and asked them to immediately start building a 60-meter-deep well, and it was the kind that could seep water.

As for whether they can reach 60 meters, Li Yi can definitely exceed 50 meters as long as they do what they can.

Of course, if there was no water like this, Li Yi would only have to take out two more Devourers......
