The next day, Ah invited his people to collect bamboo.

The two of them went to observe the large pit soaked in flax.

Take a closer look at the big pit.

Sure enough, there is a salinity phenomenon in the pit, because although the pit is a low place for the main cave, it is on a small hillside, and against the mountain wall, there is a protruding mountain stone on the mountain wall, such as the eaves block this big pit, for this reason, every time only a heavy rainstorm can make the pit full of water, if the rain is a little smaller, it will not come here, and the heavy rain, almost a summer specialty, therefore, gradually, this has become a small salt pond.

"No wonder there are no mosquitoes here." Ahh said.

"Well, the twine is clean and strong, and maybe it's because it's soaked in salt water, so we can try to process the fur."

Ah praised it, and brought a piece of rabbit skin for testing.

Rabbit skin is relatively tender, and when dealing with rabbit skin, you always have to get rid of the fat on it.

Fu Xi took the rabbit skin and washed the grease on it by a waterhole.

For this kind of cleaning, there is a cleaning agent that can be used, that is, honey locust.

However, in the process of liking to apply plant juice, apes easily discovered the degreasing effect of honey locusts.

It is also clear that this kind of washing can kill the insects in the fur so that the fur will not be damaged.

It's just that under the fact that the tools are not too handy, such processing will still leave a lot of fat under the leather.

Ah Xi was very dissatisfied, but Fu Xi thought that this was already excellent.

The two of them scraped a lot of white salt frost on the side of the salt pond to use it as salt, and then put the fur into the salt pool to soak.

It's just that when I tried to use those salt creams, the alkaline smell made the little girl vomit non-stop.

Undoubtedly, it was saline, not salt.

"It seems to taste a bit like honey locust." Ahh said.

Fu Xi tasted it, and indeed, both had an alkaline taste.

"I should be able to wash grease and skin, too." Fu Xi said.

"Mm-hmm, maybe the skin in that pool can be as clean as flax." Ah Ha was happy and found another interesting new material.

Sure enough, a few days later, after making some bamboo tools, when the two of them went to look at the skin, the skin had become very clean and tough, and the fat had been melted clean by the saline water.

Ah took out the skin to dry,

After drying, the skin was very hard, but this only surprised and delighted the two of them.

The sturdy leather is exactly what the two wanted.

Fu Xi used a round stone to roll and press it, so that the skin became a little softer again.

So, in a few months, the silk clan updated their equipment again, all of them were replaced with powerful bamboo shields, and were equipped with sharp bamboo javelins, bamboo spears, bamboo daggers, stone knives, as well as leather scabbards and leather clothes.

But this time, the Silk people will no longer easily tell the ape-men how to make these equipment.

They want to learn, so they can experiment and figure it out on their own, and there are some things that they may be able to figure out.

As for the use of fire, the Silk Clan is the only ape race in the world that uses fire, and those apes don't want to use fire.

Fire, for them, is very dangerous, they will only be afraid of the fire.

If it's farther south, there won't be a fire, because it's hot, and there's no need for it.

Even, the ancient people further south, who can only be said to be savages, did not have the conditions to produce ape-man, let alone fire.

Because the tropics and even subtropics are not cold enough, wild people do not need to hide in caves.

This is evidenced by the fact that savages were able to walk upright, that they lived together in the wilderness, and that they used their upright form to guard against the invasion of wild beasts, and that was why they evolved into an upright form over countless billions of years.

Yes, it is evolution, not evolution, in fact, everything only evolves, it is never evolution.

This is like monkeys, they don't live in caves, they would rather gather in trees, because if it weren't for the cold, the cave would have always been only the choice of the strong, for the weak, it was just a dead end, and all the weak people evolved the ability to escape, so the monkeys climbed trees and became very dexterous, but that was obviously not evolution, they were not stronger than apes.

The theory of evolution has always been a devilish evil way, and the existence of this demon is not only to deny the longevity of human civilization, but also the basis of bacterial evolution.

It can also be seen that the wild people who do not even have caves are not equipped to use fires.

The use of fire is inevitably produced in temperate regions.

Only temperate rainforest areas have all the conditions for fire.

Even, fire is still very dangerous to the Silk people.

Although the Insi people discovered that the charcoal buried in the ashes could burn slowly for a long time, the danger of charcoal poison was not so easy to discover.

For this reason, after using the fire for several months, this problem has not been found.

Then the properties of fire are not fully mastered.

After that, the Silk people were even busier, they kept small beasts in captivity, picked seeds to grind biscuits, dried brine, made salt, cured meat, and made bamboo supplies, and prospered.

However, the terrifying situation of the mountain was still deeply imprinted in Zhang Jingtao's mind.

And with the busyness of the silk clan, summer goes to autumn, the weather is already very cold, and it is about to be winter.

As a result, the silk tribe ushered in the last tribal gathering before the winter.

And for this kind of gathering, most of the clansmen will go to it.

There will be this, it is the need to survive, in fact, it is to show that your clan is strong, so that others will not fight your own ideas.

At the same time, it is also to prevent what will happen to the tribal assembly, for this reason, the old people of the tribe are going to go, once something happens, they will try their best to protect the young people, sacrifice themselves, very tragic, but for the descendants of the clan to survive, it can only be so.

It's just that there will be some old people who are too old to walk in each clan to stay, but such old people often can't resist the cold in winter and are frozen to death, or in the past ape-man wars, they are killed, and few of them live to be unable to walk.

In addition, only ten strong men were guarded from the nearby high places to guard against wild beasts.

Ah put a few sheep that had just been cut by her wool into the main cave to prevent them from freezing, and she and Fu Xi hugged their wool and slept comfortably in the fire hole, and the entrance of the cave was barricaded with some fences, and spear grass was tied to the fences.

And doing so, although it blocks a lot of cold, also reduces the entry of living energy.

This is the first time that people live in a fire cave after the cold weather, and Ah He also followed the method of using fire summarized in the past few months, put the black charcoal that was poured out and dried before it was burned into the fire, and after burning, put it in the ash on the side, such charcoal can be burned for a long time after being buried in the ashes, so as not to extinguish the fire after one night.

Then she went to sleep.

The fire is getting darker and darker.

Charcoal poison was like the breath of death, slowly infecting the entire cavern.

But there are all the silk children in the cave.
