The heavy work that Lu gently said is to build a house.

The five people of Wind and Knife were sent away, and the rest of the people began to roll up their sleeves and build houses.

One of the most important raw materials was the pure black clay at the bottom of the rift valley, and Dacheng and Chong made a few stones to block the flow of the water, and quickly dug out a large pile of clay, Lu gently made several huge wooden barrels, leaving two ears, and Ershi and Yitu made two ropes out of vines.

The pure black clay was first fed into the barrel, the rattan rope passed through the barrel's ears, and then the rift pulled the barrel up and down with all its might.

Buckets of clay were poured on the ground and piled up into a small mound.

However, this clay can only be regarded as a condiment, and the main building material is not this, but ordinary soil that covers the mountains and fields under the snow.

After all, all the soil needed to build a house in the future will be used in the rift, and the rift will one day be dug into an abyss.

They peeled through the snow that had not yet melted and found a yellowish-brown soil with fine grains.

Although the soil is still very hard at this time, the main force of building a house, a heavy city and a big city are all powerful masters, Lu Qingqing now has the power of the golden claw, and the remaining Yao and Gen are coolies who have to contribute, and the cooperation of the five people, whether it is digging the soil or adding snow water to stir the mud, it is not so difficult.

Lu gently divided the yellow-brown soil into five equal parts, one part without pure black clay, and the other four parts were added one by one, two, three, and four percent of pure black clay, and then kept stirring with sticks, kneading with hands, and stepping on with feet, making sure that it was mixed evenly, and became a mud pile with suitable humidity.

At the same time, Ershi and Yitu collected a lot of grass stalks, whisker-like roots, etc., and Lu gently added these things to the mound and mixed them well—adding these filling materials to the wall can improve the bending and shear resistance of the wall.

The plateau is not like the rift valley, the plateau is full of trees, still alive but the branches and leaves are gone, completely dead, there is wood everywhere.

Lu gently led everyone to cut down a lot of thick and straight trees, took one of them, made several long strip-shaped molds, and when the mud pile was ready, he put the mud into the mold, filled it full, pressed it firmly with his hands, and then turned the mold over, and brought out a regular and large mud brick.

When Lu Qing was a child, he had seen adobe houses built in the countryside, and those experienced masters did not use molds, but directly started to throw the mud ball on the ground a few times, and they could fall out of a long square mud brick.

Lu Qingqing naturally does not have this technology, so he can only honestly use the mold.

In fact, she is more like burning bricks to build a house, but that is technical, first of all, there are requirements for soil quality, and secondly, a brick kiln must be built first.

It is necessary to test over and over again to master the trick, and Lu Qingqing can't afford to consume this time this time.

Once you have the mud bricks, you move the mud bricks to the side, and wait for the mud bricks to dry.

In the process of waiting, Lu gently cut down the other trees he cut down again, got the required length, and led everyone to build the basic framework of the earthen house.

She considered that in order to improve the safety of the adobe house, the all-adobe house felt a bit overhanging, but if the wooden frame was used to bear the load, it would be more reliable and safe.

They cleared out five open lots, the ground was leveled, each of which was only two by two by two square meters, and four load-bearing columns were inserted at the four corners. With infinite strength, he picked up the trunk of a tree with a diameter of more than 20 centimeters, aimed the sharpened end at the ground, and with a loud shout, he inserted the trunk that was not so sharp into the ground that was still hard and erected, and it was at least twenty or thirty centimeters into the ground, which was very stable.

After placing the load-bearing columns, put the beams above the load-bearing columns.

Lu lightly cut a square groove at the top of the load-bearing column in advance, and the beam connected with it was cut out of a bulge that matched this square groove. However, it's not that Lu Qing doesn't understand this half-understanding, and he can't make a high-grade tenon structure for the time being, so I'm embarrassed to call this square groove an eye, and a bulge called a tenon.

In short, the connection between the beams and the pillars is still compatible, but because it is made by Lu lightly, this structure is not stable, and auxiliary ropes are needed.

Thick vines and thin vines are not things that are everywhere, Lu gently consulted everyone, and finally locked the rope into the inner skin of the tree.

It is to peel off the bark of the dead tree, tear off the layer of wood fiber in the bark, knead it into a rope by hand, and then continue to lengthen it, so that the rope is very strong and flexible, and it is very suitable to fix the beams and columns.

The result is a square timber frame, and the next step is to move on to the roof.

It is uncertain how the precipitation will be, if the rain is abundant, then the roof should be made higher and steeper, and vice versa, it will be gentle, Lu gently built a roof that is not steep or slow, and fixed the beams one by one with inferior mortise and tenon structures and ropes.

It took the afternoon of the first day to haul the mud, find the mud, and dredge, and the second day to make the mud bricks, cut down the trees, and complete the timber frame, so on the third day, when they started work again, the mud bricks were basically dry, and they began to build the earthen wall.

These five houses have no foundation, and there is no need to make a foundation as a test room, but Lu Qing still picked up some fine stones and pounced on a layer below to strengthen the ground, and then selected a relatively regular large stone, and built a height about the height of a calf as the foot of the wall, and the pure black clay between the stones was pasted with water and became more and more sticky.

On top of this layer of stones, the mud bricks began.

As I said just now, the mud bricks have become dry and hard, and there is a clear distinction between the mud bricks and the mud bricks, and Lu Qingqing still uses pure black clay as a binder to bind them. The effect of this pure black clay is naturally far less than that of cement, but it is not a problem to stick these mud bricks.

They built the wall very smoothly, the doors and windows were also left, and the four walls were quickly completed, Lu gently let a fire burn in it, dried the wall, and then everyone went to build a second room.

The four laborers—Lu was small and short, and she began to climb up and down, and after Dacheng and restarted, he began to dislike her and drove her to the side to supervise the work—it took a whole day to finish five houses, and the roof plan was originally to be made tomorrow, but everyone couldn't wait to live in the house they built a day earlier, so they worked overtime hungry one by one.

For the roof, Lu Qing had two ideas.

One is to split the wood into pieces of wood, with a moderate thickness and width, and then spread them piece by piece on the slope of the triangular roof.

But this scheme is problematic.

Because there are no nails, the planks must still be fixed by ropes, so there will definitely be a gap between the planks and the boards, and the rain will still hit and the wind will still blow in.

This is actually the reason why Lu Qing gave up building a wooden house at the beginning, it is difficult to guarantee that it is strong, and it will leak wind and rain.

However, it is okay to paste a layer of mud on the wooden board, but then Lu Qing will worry about the load-bearing problem, after all, they are not very professional projects, and the safety remains to be seen.
