Three hundred warp threads may not seem like much, but calculating the length of the sum and the length of the weft, how much bark you want to pick up and how long you can rub the thread, Lu Qingqing feels that her idea of weaving cloth is not too practical.

The cost and labor cost are too high.

But compared to animal skins, hunting is risky, animal skins are too difficult to transform and not breathable, although the cloth she made, although it is still thick and rough, but it can be made into clothes to wear.

Lu lightly struggled in his head for a moment, then put all these thoughts away, and looked firmly at the simple weaving tool on the ground, no matter what, this piece of cloth was woven first.

This is a very grand project, Lu Qing is not in a hurry, rubbed the line again, suddenly remembered something, and got up and walked upside down.

Lu lightly wanted to make a stone mill.

Those soybeans are there, although the first thing Lu Qingqing wants to make when she sees soybeans is soy sauce, but she will not forget the white and tender tofu.

If you want to eat tofu, you must grind it on a stone mill.

In her previous life, Lu Qing had a small hand-mill at home, which she had disassembled and rinsed countless times, and she knew its structure well.

Then the stone mill is generally made of granite, which is a kind of granite, with greater hardness, not easy to crack, good compressive resistance, and temperature resistance and wear resistance.

However, in the process of "torturing" stones everywhere these days, Lu Qingqing found that the most common stones here are gray-yellow and cyan stones, which are the kind of stones used by the clansmen to make weapons, followed by slate, mudstone, sandstone, etc., and granite is relatively rare.

Don't ask her why she knows so much about rocks, she has studied in junior high school natural science, and she doesn't understand more, but slate has an obvious plate-like structure, along which the texture can be peeled into thin slices by hand, and the color is varied.

As for the gray-yellow translucent blue stone, Lu lightly suspected that it was bluestone, that is, the bluestone of the bluestone slab, and the one commonly found in the stone stele, which belonged to a kind of limestone, a relatively common stone.

The kitchenware used these days is made of bluestone, but if it is used to make stone grinding, Lu Qingqing still tends to granite, bluestone is not dense enough, one is lighter than granite, and the other is not hard.

Incidentally, Lu Qingqing's favorite ones are granite and marble, the former is the king of rocks and high-grade building materials, and the latter can be polished smooth and smooth, and then spread on the ground and roll around.

It's a pity that the former is rare here, and the latter has never been seen at all.

Lu gently regretted in his heart, and found it for a long time, and finally found a large stone that was suspected to be white granite under the cover of a soil layer, this stone only showed a face, and the whole body was embedded in the soil, Lu gently planed it out for a long time, the volume was huge, half a person high, and there were black and white spots distributed on the surface.

Lu gently swirled around it, and scratched his upper paws again, the hardness was greater than those previous stones, and he was satisfied that this was a piece of white granite.

Lu was about to start when he heard a "roar".

She was startled, and listened intently, it was the sound of roaring, he and the knife went to find the way, and now returned?

Lu Qingqing immediately put down the big stone in his hand and hurried back.

The knife and the roar were dusty, the knife seemed to marvel at the five adobe houses, and the roar described their process of finding their way with emotion.

Needless to say, it is difficult, sometimes I get lost, sometimes I have been detouring, and I have fallen and rolled down countless times because the road is difficult to walk.

Luckily, they found a way.

"The knife has drawn a picture, let him tell him. "It's okay to roar and tell stories, but when it comes to seriousness, I will abdicate and make way for Xian.

The knife took out the map, which was the kind of skin that Lu lightly drew a topographic map, and Lu lightly gave the wind and the knife a big one, and taught them how to draw the map, and then drew the route back to her.

The diagram drawn by the knife is really a bit indescribable, a lump of unknown objects will replace this plateau, and a few twisting lines are the main road up and down the plateau, except for himself, probably no one can understand it.

However, with the knife's narration, Lu Qing understood a little.

The plateau where they were, except for the almost completely vertical cliff they came up from, the rest of the place is generally quite gentle, but the mountain is complex, full of grass and rocks, and there are not cliffs, faults, potholes, Dao and Roar walked through it himself, and walked out of a relatively easy road, although this road is crooked, but it also shows Lu gently the route to choose from in the future.

Lu looked at it for a long time, thought for a moment, and said, "You guys have a day off first, and then take me for another trip tomorrow." ”

"Young Chief, I can take you there now. ”

"You've been tired for days. ”

"I'm not tired, I used to grope and walk with Roar, and it took a few days, and now let me go again, and I know how to go, and it's very fast. ”

Lu thought about it lightly and agreed.

Lu gently took Ershi, her guards went with her, and Dacheng also came.

It took more than half an hour to walk on this vast plateau to reach the descent road.

There was no road at all on this downhill road, it was messy, and the snow had not completely melted, but fortunately the knife wittily made a mark, and walked all the way around for more than two hours, which was very slippery and hard.

Lu gently stood below and looked around, it was still between the mountains, a bit like a canyon, but walking out along the winding natural path, you could walk to the great plain outside.

She looked up at the mountain in front of her, and from below, she would only think that it was an ordinary hill, but at an altitude of more than 100 meters, no one thought that there was an incomparably open space on it.

Lu gently picked up a pen sharpened from charcoal, and on the sketch of the knife, intercepted several of the routes and connected them to form a road that was shortened by at least two-thirds.

Then he led a few people to climb up along the drawn route, and made very conspicuous marks along the way.

This time it was even harder, some places required to use both hands and feet, and some places were big pits, and if you were not careful, you would fall into them.

Lu gently climbed to the top, patted the mud on his hands, and said: "Roughly follow this route to build the road, get rid of the grass, trees and stones, first open a road, and use mud and stones to pad the uneven places, and then pave the whole road with bluestone slabs to create a step-by-step process." ”

She paused and said, "Building roads is not a trivial matter, and when the weather warms up, we will work together to repair them." "The main thing is to find a few people who can lead this work, Lu Qing knows that she is two pounds, and she is generally okay, but if it is implemented, she will not be enough.

She walked around again and asked the big city: "The mountain road has been decided, where do you say it is best to build a tribe?"

Ayutthaya said: "I don't think it has to be very close to the mountain road, there is a large area of land around here, just look at the water source." ”
