After collecting in previous years, the women would start making winter clothes for all the tribesmen.
They would take out the animal skins, dry them in the sun, and then simply cut them into the desired shape with a stone knife.
The so-called clothes are just large pieces of animal skin wrapped around the body, and animal skins and hay are also used as quilts when sleeping.
But this year it's completely different.
Since Xu Chen invented spinning and weaving, women almost no longer go out to collect. Apart from arranging for the tribesmen to eat, drink and have sex, everyone is busy spinning and weaving from morning to night. They are busy until late at night every day. Some people even
He slept even later than Xu Chen.
And in their busy schedule of working overtime and forgetting food and sleep, there are more and more sackcloths.
With cloth in hand, a few ingenious women began to make clothes for the tribesmen.
The men wear big shorts and T-shirts, and the women wear mid-length skirts with folded plackets and short sleeves.
Although they are all a bunch of crappy tailors and their clothes are sewed crookedly and unbearably, the cloth is light, breathable and easy to put on and take off. Therefore, all the primitive people who put on the new clothes suddenly screamed with excitement, like a group of monkeys.
The hozens were dancing wildly in front of the cave.
In order to cooperate with the women in sewing clothes, Xu Chen had to spend several days with two men making bone needles.
It is easy to polish the bone needles, but it is extremely difficult to drill the nostrils.
After drilling through several bone needles one after another, Xu Chen decided to invent an unprecedented complex tool - the wooden bow drill.
The wooden bow drill is one of the most commonly used tools by rural carpenters. The principle is very simple. It uses the balance wheel to drive the wooden pole to rotate left and right, so that the rope like a bowstring is wrapped around the wooden pole, thereby forming enough torsion. When the kinetic energy of the balance wheel
After everything is transferred to the rope, press the bow arm down, and the rope will drive the balance wheel to rotate in the opposite direction. In this way, the drill bit can continue to work without stopping.
Of course, the principle is indeed simple, but given that there are no tools except stone knives and stone axes, it took Xu Chen two days to complete the wooden bow drill.
Just making the bow arms took a day.
Because there needs to be a hole in the middle of the bow arm for the drill rod.
But under the current conditions, it was extremely difficult to punch a hole in the middle of the wood, so he came to his senses after working for a long time. He cut a depression into the middle of each of the two wooden sticks, polished it with a stone until it was roughly rounded and smooth, and then put the two halves together.
, and then tie them together with hemp rope to make a bow arm with a hole in the middle.
With the bow arm, it is much simpler. The method of making the drill rod is similar to that of the arrow. You only need to find a suitable sharp animal tooth and clamp it on the drill rod head, and tightly tie it with hemp rope. As for the balance wheel that drives the bow arm to swing,
Just choose a suitable stone and tie it to the drill pipe with hemp rope.
Looking at the unprecedented complex tool that Xu Chen spent two days inventing.
The two tool men who followed to help polish the bone needles were astonished.
Especially when Xu Chen demonstrated drilling, the two of them were almost completely stunned.
Although this wooden bow drill has a simple and rough structure, it is a typical tool of the primitive era.
But after it actually turned, it was no different from the wooden bow drills of later generations. As the bow arm pressed down, the balance wheel and the hemp rope continued to rotate back and forth, and the sharp teeth soon drilled a small hole in the test bone piece.
.
It worked, but Xu Chen regretted that the drill bit was just a tooth. Because it had no cutting edge, it relied on sharp tooth tips to grind it, which caused the bone to crack due to the impact force.
Teeth are the hardest organ of all animals. Tooth enamel is not only harder than bone, but even harder than ordinary steel.
Men often brag that they are as strong as steel, but in fact they are too conservative. Their teeth are the hardest.
But it’s hard to use, it has to be easy to use.
Just like the wooden bow drill currently invented, the effect is unsatisfactory, just like a man bragging, it looks good but is not easy to use.
Xu Chen's wooden drill kept buzzing,
After drilling several more pieces of bone, I finally got a piece of bone with a suitable hole size, which I gave to the man to polish carefully.
The invention of any reasonable tool will improve work efficiency.
The same is true for the wooden bow drill. Although the effect seemed poor to Xu Chen, it looked like an artifact to the two primitive people.
In just one meal, Xu Chen drilled three bone fragments in one breath. Of course, more were drilled to waste. He finally smashed the selected suitable bone fragments, and at least 70% of them were broken.
However, although teeth are hard, they will still be scrapped quickly under such high intensity of wear.
So Xu Chen had to continue looking for sharp animal teeth to use as drill bits.
Suitable animal teeth are not easy to find, because only beasts like wolves have sharp canine teeth. In the past, tribes rarely hunted adult wild wolves. In fact, there were very few wolf teeth, and most of the wolf teeth were taken by a group of men.
Made combat decorations.
Therefore, Xu Chen had to do the next best thing and ask the man who made the stone axe to help make a few stone drill bits.
But the stone is obviously not as strong as the wolf's teeth, and it will be scrapped faster when the bone fragments are drilled.
So he had to consider changing the material of the needle.
Bones are used as needles because they are hard and not easy to break. If you don't consider using them for a long time, wood should also be suitable.
So he found some materials left over from making bows, split them into small pieces of wood with a stone ax, and then drilled the holes. It was much faster this way, and the wear of the stone drill bit was also very small. He polished it into wooden needles and tried it, and it worked.
.
In this way, he successfully solved the problem of insufficient needles in the tribe.
With enough needles, women can sew clothes much faster. In their spare time, they also find many animal skins worn in previous winters, re-cut them and sew them into new clothes.
In his spare time, Xu Chen also taught them how to sew winter clothes into long-leg pants and long sleeves.
In addition, some remaining linen and animal skin scraps can be sewn into bellybands, bras and panties.
However, when he saw a woman who was inspired by him to sew a pair of animal skin shorts and put them on a child, he felt his eyes begin to flash, and he vaguely saw a group of male and female savages wearing animal skins, dancing in the bright light.
Under the bright sunshine, run wildly in the primeval forest.
…
The original days were busy and leisurely.
As the moon dims again and enters the next cycle, the autumn colors become more intense.
According to the time calculation, it should have entered the eighth month of the lunar calendar, which is around tenth month of the solar calendar.
In the mountains and fields, a large number of broad-leaved trees are beginning to turn yellow. Although their leaves have not yet fallen, the temperature is getting cooler day by day.
If you don't wear clothes in the morning and evening, it will be irresistible.
Especially when sleeping at night, you already need to cover yourself with hay and dirty animal skins.
Fortunately, thanks to the hard work of a group of women day and night, more and more cloth was available, and the tribesmen gradually began to wear linen clothes. Some who had not yet waited for cloth wore newly remade animal skin clothes.
Xu Chen spent a few days and took Gu Heju to dig out the water pit for daily drinking water and wash. Then he built a square well with pottery bricks, lime clay and mud. At the same time, he dug several mud pits where the water flows below.
After digging, drain the water, and then use clay bricks to build several sinks for washing vegetables and washing.
After such renovation, the cave looks more neat and beautiful.
The emergence of these pools has also greatly improved the water hygiene situation.
Because there were enough clay bricks fired this time, Xu Chen built a low brick platform around the fire pit as a bench, which made it convenient for eating and warming up.
The plant thorns on the riverbanks and hilly areas below the mountain have begun to wither and turn yellow.
The women's collecting activities have completely stopped.
A stone wall has now been built around the kiln, with a height of about one and a half meters. It is not too high, but it is enough to stop ordinary wild animals.
In the valley, since the group of wild wolves were wiped out, and after the continuous hunting and expulsion by Feng and others, except for some wild boars, foxes, pigs, badgers, jackals and other animals, there are no large beasts that seriously threaten the safety of the tribe.
, so this fence is enough to ensure the safety of kiln workers.
Of course, for greater safety, doors are still necessary.
Therefore, after the wall of the kiln was repaired, Xu Chen took two men who made tools down the mountain to prepare to repair the gate of the kiln.
The gate faces the river beach to facilitate the transportation of stones and water.
More than a month has passed since the construction of the kiln factory began. People come and go every day, and a road has been trampled in the direction leading to the river beach.
In addition, most of the men have been busy in the kiln factory recently, and the thick smoke caused by the kiln firing every day has made the foot of the mountain completely different from the desolate primitive scene a month ago. The atmosphere is very lively, and it does not look like a group of primitive people at all.
The scenes of people's lives are instead like a certain mountainous countryside that I was once familiar with.
Especially after a group of savages recently put on linen clothes.
The gate of the kiln factory is almost three meters wide.
According to the current conditions, it is quite difficult to make two doors of this size.
Because stone knives and stone axes cannot cut down trees that are too large.
However, there is no need to use thick trees for the entire gate. The main thing is that the two rotating door shafts must be strong.
The three of them wandered around the forest near the kiln for half an hour, and then selected two small trees as thick as thighs.
The task of felling the tree was naturally handed over to the two tool men. Xu Chen took Gu Heju and started building the doorposts with clay bricks.
The original stone wall was very rough, with a trapezoidal structure that was wide at the bottom and narrow at the top. In order to erect the gate, the door wall had to be built straight and flat, so that the gate could be fixed.
It was only two trees as thick as thighs. Two men spent a whole day on the mountain gnawing at them before cutting them down. Several stone axes were chopped into pieces.
After the tree fell, Xu Chen took a rope to measure it and then continued to cut it.
The two of them gnawed and chopped for most of the day, and finally got two two-meter-long tree trunks.
A group of people from the kiln went up the mountain to help lift the two logs down, trim them according to Xu Chen's requirements, then peel and dry them.
In the past two days, Xu Chen and Gu Heju also built the door walls with ceramic bricks on both sides of the door. In addition, they found two flat stones, with the middle slightly dented, and placed them on both sides of the door pillars as door shafts.
stone.
After the preparation work is basically completed, the only thing left is to make the door.
