"It's a good question, I've thought about it before, you say that if you seep into the soil, it will be dirty and wet, and the rain will be better, but if it's domestic sewage, it will be terrible. Lu lightly felt that this problem was very serious.

"Actually, it's not just this problem, I've thought about what we have laid on the ground, is it just bare land? When it rains, the city is muddy, it's not annoying, I really want to pave all the bluestone, think about the bluestone slab bluestone road bluestone square, how good......"

"Young Chief, you just said that we are not qualified to make that tall. The wind silently interrupted Lu's unrealistic reverie.

“...... yes. "Manpower is a problem, and there aren't so many bluestones for her to toss here.

Lu wilted slightly.

It would be nice to have cement.

Cement floor cement house, how neat, bright, and atmospheric? The problem of the ditch is still a fart, a touch of cement, see where the water can seep into.

It's a pity that she wasn't so atmospheric enough to DIY cement before.

She looked at the scene of the bare-chested strong men beating the adobe not far away, and sighed, she only had adobe, adobe, adobe......

Speaking of adobe......

"By the way, have you re-studied what proportion of adobe is the strongest?" Lu asked gently.

The wind was stunned, but fortunately, he was already a little accustomed to the thinking of his young chief, and he said: "There is a result, pure black clay accounts for 10% and 20% of the kind of adobe, it is said that it is easy to crack without clay, and if there is too much clay, it is particularly sticky and slippery when it is stained with water, which is not good." ”

Lu nodded lightly: "Then add clay in a ratio of 10%, in fact, the soil quality here is not bad, and the ordinary soil also has a certain degree of cohesion. ”

The wind made a note of it, and then continued to remind: "Young chief, the ditch ......"

Lu pinched his chin lightly: "Otherwise, I'll see if I can burn bricks?" Even if the quality is not up to par and can't be used to build a house, it shouldn't matter if it's used to pave the ground...... Well, it may be easier to crush, but if it is broken, it is better to change it than to be muddy and slippery on a sunny day, dusty on a sunny day, and slippery on a rainy day. ”

That's how attached you are to the ground.

Feng silently swallowed the words in his mouth, and saw Lu lightly rushing to the adobe field with an excited look.

Halfway through, he turned back and said in a hurry, "Arrange for someone to cut down the trees, I forgot that it takes a lot of wood to build a house." ”

"But we haven't started building a house yet. ”

"Then you have to cut down the tree first, the wood has to be dried before it can be used, we used to be non-standardized. ”

Fortunately, the bark of countless dead trees was peeled before, which was equivalent to promoting their drying in advance.

"Pick a thick and straight one to cut first, and then put the branches and other things on the side, if you can't be busy, I'll let them take it back." ”

It takes a lot of firewood to burn bricks.

Lu said softly and left in a hurry.

Although she grew up in the countryside when she was a child, if you want to ask Lu Qingqing how the bricks are burned, Lu Qingqing doesn't know anything at all, and even asks her what kinds of bricks there are, she will only answer green bricks, red bricks, cement bricks, oh, it can also be divided into solid bricks and hollow bricks.

She vaguely only knew that bricks were fired from clay, but she didn't know exactly what the ingredients were, but when she grew up, she watched some wild survival shows, and then found out...... Hehe, it's just a piece of mud to knead it, dry it, and then pile it on the ground, cover it with firewood, okay, burn.

It's not particular about it.

But it can really burn things that look like bricks, not bricks, pottery, and non-pottery.

Lu lightly felt that others could, and he should be able to do it himself.

She ran into the mud, and the strong men were called by the wind to cut down the trees, and she was slowly pondering by herself.

A pit had been dug out of the field, and the earth had been dug out to make adobe, so there were not only a lot of smooth and shapely adobe, mud masses that were stirring with water, mud piles that had not yet been treated, and mud profiles that were clearly visible after being excavated. and pure black clay that was carried by a load after a load.

No way, the cart hasn't been built yet.

Lu gently rubbed a piece of pure black clay, and rubbed it with his fingers, and the clay was rubbed like a dough sheet, delicate and sticky, moist and oily, just like plasticine.

Lu Qing couldn't help but feel a pity, the plasticity is so strong, how good it would be if it could be made into pottery, it would be a pity to use it to build a house.

The thought flashed, and she couldn't help but feel a stir in her heart, can this be made into pottery?

Lu thought lightly and dug up a large ball of pure black clay, and took the most common yellow soil, and took different colors and textures of soil from the soil profile, including brick-red fine crushed soil, sand-like soil obtained by crushing gray-white loose rocks, and dark black soil that looked very fertile.

She ran to the firewood pile to find a thick round wooden stake, casually split out a few flat wooden plates, separated the different soils, there are large particles either picked out, or smashed with a wooden stick, and then add water, and mud, knead the mud, among which the brick-red soil looks finely broken, the viscosity is actually very good, and the gray-white soil is almost the same, kneaded into a ball, Lu lightly had to give up it.

In addition to smashing and falling, Lu gently returned the mallet and thrashed it, making the mud ball softer and more even.

"Young chief, what are you doing, playing with mud?"

Chong and another person came over carrying the freshly cut tree, and Chong screamed when he saw Lu lightly pounding a few lumps of soil.

Lu didn't raise his head lightly: "I'm studying these guys." ”

He put down the tree and waved at the other person: "You go first." Then he ran to Lu Qingqing's side, "Then you have to call me, I have experience." ”

Lu Qing finally raised his head: "When did you have this kind of experience?"

"The house that I have been staring at for days is not in vain, and the adobe that has been beaten here for so many days, others have learned from me. ”

Lu looked at him lightly with an excited look on his face and said with a smile: "Are you quite proud?"

"Alas, I didn't do this kind of thing before, I like to fight and kill, what's so fun about mud, but I don't think like that now, there's so much fun in this mud. ”

Lu lightly looked at the black line, and continued to pound his hand: "What fun can it be?"

"Anyway, I think it's very interesting, what are you going to do, young chief, tell me I'm coming, you see your tender little hands, how bad it is to get this." ”

Lu thought lightly: "Okay, I want to make bricks, that is, the mud becomes hard after being burned in the fire, which can be used to build houses and spread on the ground, and I also want to make pottery, pottery, you know, there is only one black jar in our tribe that is still regarded as a treasure by you." ”
