Baili Huang followed Situ Kong to the vicinity of the valley outside the city, where was the place to dig a pool.

"Young marshal, some people have come here to explore the water source before, saying that this is a dry hill and there is no spring!"

Situ Kong glanced at the villain sitting on Dazhu's shoulder, and only felt that she didn't look like a child at all.

Nonsense! They have lived for three hundred years, and they are certainly not children!

"They don't know how to look for springs, we have the bottom of the valley here, but there is groundwater, how can there be no springs?"

Baili Huang rolled his eyes, and the underground river just ran through the city and the Desperate Mountain Range.

"Groundwater? Is there really water flowing underground? ”

For the first time, Situ Kong had heard of the idea that there was a river underground.

Baili Huang's divine sense spread out and looked at the groundwater near the city.

Groundwater is formed when rain and snow seep into the ground.

Groundwater flows or accumulates in the ground along crevices and ravines.

Flowing groundwater forms underground rivers.

The continent has been dry for several years, and the water level of underground rivers has dropped dramatically.

Fortunately, the underground river here is not the kind of karst landform that is claimed.

The underground rivers of this continent are the kind of rivers that seem to flow on the surface of the stratum, and they are transferred underground.

So digging a big lake on this hill will not collapse.

Underground rivers can't flow high under any circumstances, and they still rely on water spirit beads.

Now that the continent is short of water, it is only possible to obtain water from underground rivers in this way.

Anyway, the formation of the spring also depends on the underground river, and putting a water spirit bead is just a guide.

"Young marshal, so let's leave the underground here in the city, and there is still a lot of water?"

After Baili Huang's narration, Situ Kong felt that he was simply an eye-opener.

"That's right! I don't know about the rest of the city, but I still know about this departure from the city? ”

Baili Huang took out a compass and walked up the bottom of the valley.

At this time, in the place selected by Bailihuang, everyone was already digging a pit.

The people digging the pit were the group of refugees outside the city, plus the people led by Situ Kong were digging.

The size of the lake has been determined, and the bottom of this valley is very flat, just right for digging a large lake.

When the time comes, two water wheels will be erected by the lake, and the water will be transported to the reservoir in the surrounding land, which will definitely be enough for watering.

There are no rivers here, so water wheels can only be pumped by manpower.

The pumped water flows down the bamboo channel into the cistern.

Situ Kong looked at Baili Huang holding a compass, she was like an encyclopedia.

"Young Marshal, what else are you looking for?"

Dazhu followed behind Baili Huang and followed closely.

"Oh! I'll see if there can be a spring upstream, so that there will be a flow of water, and the upstream water will flow directly into the lake, and our waterwheel will save effort! ”

This valley outside the city, judging by this location, should be in the middle of the Desperate Mountain Range.

I am not afraid that there is a lot of water in the valley, and the more water flows along the valley to meet the water flow under the cliff of the cottage.

Bailihuang went all the way to the end of the valley, where there was a concave mountain.

Looking at the opposite side of the concave mountain, it happens to be a small convex mountain.

"Hahaha! Got it! ”

Baili Huang ran to the bottom of the concave mountain, and sure enough, the land in this place was a lot wet.

And there is moisture on the mountain.

Situ Kong saw the happy Baili Phoenix, and felt that she was like a child at this time.
