"I think so too. Lu said softly, "Just wait for the wind." ”

Before they could hear from the wind, they waited for the clansmen to come.

Standing on the edge of the plateau and looking out, you can see the vast Qingluyuan in the distance, one or two people may still be obscured by obstacles, but if you are a group of people, it is easy to see.

When the team was about to arrive, Lu gently went down the mountain to pick them up.

There were thirty men in the group, twenty of whom were strong young men, five were experienced old men, and five were women.

Lu was very happy and arranged for twenty young people to dig the soil.

Fifteen young men were asked to dig up the adobe material beside the large open space that had been demarcated where tribal dwellings might be built, and the overseers of the fifteen men were the experienced ones who knew what kind of soil to dig up, and how to remove impurities, knead and beat them when they had been dug up. Five other youths went down into the rift valley to dig up pure black clay and hoist it up before carrying it to the clearing.

Five old people, let them study the five adobe houses, make a better house design, this design can't be done for a while, it doesn't matter, when the time comes, everyone brainstorms, the more important task is to make some doors and windows of uniform specifications, although the doors and windows made by Lu Qingqing can be used, but in the end they are too rough and simple and too thin, not strong enough.

The five women followed Ershi and Yitu, and when they had nothing to do, they rubbed the threads—now the men had something to do, and the women themselves had to do the work of cutting and peeling the bark of the trees, and even Haruka and Root were thrown into the pile of fifteen people to continue the heavy work—when there was something to do, they went to help the handle, and then they were in charge of everyone's food.

After two more days of hard work, Wind and Ash and Legs finally returned, and at the same time brought back a sketch.

"It went more smoothly than I thought, and there was originally a river on this plateau. Feng told Lu Qingqing, "On the first day, we didn't find anything, so we hurried away, and on the second day, we found a dent in the ground." ”

The trail was not particularly wide, nor was it particularly deep, the wind trio dug up the snow, and there was ice underneath, the ice was not thick, only an arm's length deep, and the ice was chiseled, and below it were smooth round stones, as well as gray-black silt, and grass that only grew at the bottom of the water, and the three of them felt that this might have been a river.

The three of them were very excited, and they walked along the possible river, the closer to the pillar of heaven, the higher and more complicated the terrain, they were almost climbing the mountain, they lost the trace of the river for a while, fortunately under the Tianzhu Peak, the ice and snow had begun to melt, and they followed the melting snow water to look down, and finally found that part of the snow water flowed into the river, which confirmed that it was indeed a river, and when it was spring and summer, there must be water in it.

They walked back along the river, and when they reached the place where they had first discovered the river, they often had to dig up the snow to determine the next course of the river, and they walked all the way to find it, and finally stopped at the rift.

"So the river ended up in the rift valley?" Lu asked lightly, looking at the sketch.

This sketch of the wind painting is much more intuitive than the one of the knife, only to see the river represented by the black line meandering out from under the Tianzhu Peak, if it encounters a hill in the middle, it will detour, and when it encounters a depression, it will gather, bend and bend and finally flow into the rift valley.

The inflow point was to the east of their place, far from their side, downstream.

On the contrary, it is quite close to the residence that Lu gently demarcated.

As mentioned earlier, this plateau is an acute triangle, with the apex Tianzhu peak located at the northern end, and then the terrain is high in the northwest, and the lower the southeast side, and the rift valley is in a trend from southwest-southwest to east-northeast, obliquely dividing this triangle almost in two.

The reason why I say almost, is because the rift valley gets narrower and narrower as it goes to the back, and finally disappears on the ground, and the open space that Lu Qing chose is in the southeast corner of the entire triangle, where the rift valley has ended, so Lu Qing feels that there can be flowing water left there, and if not, she can also manually dig a canal to lead the water over.

Unexpectedly, the water was cut off by the rift.

The wind-marked cut-off point of the river channel is very close to the end of the rift valley, and the water flowing in it has only two results: one is that the water accumulates in the rift valley and finally floods the rift, and the second is that the water leaks into the bottom of the rift valley and disappears completely.

Lu gently felt that it was the second type, because the rift did not look like it had been flooded.

She stretched out her index finger and scratched the blank space near the tail of the rift: "Is there a decent river or waterway in this area?"

Feng said: "We have searched carefully, no, maybe we didn't find it." ”

Lu shook his head lightly: "There shouldn't be, I have long found that the trees in this place are not as dense as in other places." She smiled, "It should be said that water resources are a little scarcer in the south of the rift valley than in the north of the rift valley - they have been robbed by the rift." You can see that there is so much water vapor in the rift valley, and the plants are so lush and fat, in addition to the geothermal heat under the ground, there are hot springs, which is an abundant water resource. ”

"Then we put the tribe south of the rift?" he said, shaking his head, "It's too inconvenient." ”

Lu said lightly: "Yes, it's just too inconvenient, the rift has intercepted our water, why don't we just find a way to take the water?"

In the next two days, Lu Qingqing has been conducting field investigations, and then combined with everyone's opinions, she finally decided on a completely settled place, she did not choose the large open space that was demarcated before, but chose a relatively high place closer to the rift, and the place where everyone dug was on the east side of it.

Once the location is determined, then the city will be built, and there must be a design drawing first.

A square city, the walls should be very high, at least three meters high, the walls should be very thick, at least three meters thick, so that people can run on them, and there must be battlements, and there are watchtowers on the four corners.

The front, left and right three gates, the front gate also has a city tower, and the T-shaped main road is set aside between the three city gates, and the whole city is then divided into three areas, the rear area is the largest and most important, the chief and his escort residence, the conference hall, the patrol team and other offices and canteens, set up along the street, behind it is the warehouse, the planting test base, and the martial arts field.

The front left area and the front right area are both the residence of the clansmen, that is, the living area, and the patrol duty office is set up separately for them to be on duty at night.

Lu lightly finished the sketch, pondered the problem of the sewer, and thought for a long time that the answer was that there was no solution, at this stage she couldn't get a drainage system at all, or she would dig a ditch at the foot of the city, let everyone splash the domestic water here as much as possible, and then let the sewage in the ditch flow into the moat outside the city.
