When Zhang Jingtao recalled this, although these memories flashed by quickly, he was still so nervous that he broke into a cold sweat.

Just when death was about to come, fortunately, small animals are very sensitive to charcoal poison. One sheep fainted first, and the other sheep started to scream.

Ah Hui and Fu Xi woke up immediately and clearly felt difficulty breathing. They quickly opened the fence and woke up all the children.

For this reason, the smoke and the weak fire made Ah Hui vaguely understand that incomplete combustion will produce dead air.

And vitality can make the fire burn more vigorously.

Moreover, this was discovered because a sheep was poisoned by charcoal. Therefore, if the sheep is alive, it means that it has vitality. Therefore, this vitality was later written as oxygen.

But in fact, oxygen is a superfluous fake word. It has no other meaning except to express vitality, and it will also make people confused about the origin of sheep energy.

The vital energy is originally called sheep energy.

For this reason, the water in which women give birth to children has always been called amniotic fluid, which is the vital water.

For this reason, this is how the word "fresh" came about.

Many people don't understand where the word "fresh" comes from. Therefore, foodies think that fish and mutton are stewed together to make it fresh. However, in fact, the taste is not more delicious than simply stewed fish or mutton.

.

But after knowing that sheep represents vitality, you will know that "fresh" actually means "live fish".

The dead air is called charcoal gas, which fully expresses the characteristics of fire-using civilization that incomplete combustion will produce dead air.

After having this important experience, Ajie's people truly understood fire.

Of course, understanding does not equal control.

When the Silk tribe members came back, they all looked sad.

After all, they all felt the benefits of fire, but the dangers of fire seemed impossible to completely prevent.

"Maybe we can make more holes." Ah Hui said.

"Let's go next door and have a look." Fu Xi said.

The two of them went to look at the small hole used as a ventilation channel for the fire.

At this glance, the two of them were pleasantly surprised, because the small cave was too hot. It would be fine if they were not close to the cave wall behind the fire. If they were close, they could immediately think of baking cookies.

So is it possible to move the fire into this hole and use the main hole next door as a cookie to heat up?

sure.

After this method was created, the people of the Silk tribe were all happy. Isolation between humans and fire was an extremely safe method.

Everyone took Erha and started digging holes again. This time they wanted to open a ventilation hole for the new fire hole and a new fire hole.

Such a fire is not afraid of dying at all. According to the method that incompletely burned charcoal can extend the burning time, the entrance of the hole is basically closed, so that the fire burns slowly and saves materials.

This method of saving materials comes from the use of charcoal.

Moreover, Ajie opened an opening between Caihuo Cave and Huo Cave.

In this way, when the weather is good, some of the fire stored in the storage hole can be taken and placed in the fire hole, and the fire will not be affected when it rains.

Sure enough, with the help of the mountain wall, heating the main cave is not a problem at all. This is almost the usage of a fireplace. However, the ape-men are in better conditions than foreigners and can use four holes to complete the fireplace. Therefore, this usage is very convenient.

Safety.

Later, the civilized Chinese also turned this usage into a very safe use of fire kang.

However, uncivilized foreigners, in modern times, only use very dangerous fireplaces. This is slightly recorded in a Privy Council volume called "The Age of Hellfire".

It's just that Zhang Jingtao can't remember what the mysterious volume said.

But it is conceivable that the method of separation of human and fire for heating that Ajie came up with more than 200 million years ago is really super advanced.

All surpassed modern foreigners.

For this reason, the Silk people's caves have become extremely comfortable, and even the kitchen has been separated.

After that, there is no doubt that the use of fire, weaving, raising wild animals, and the spread of some compound-sounding nouns also made this tribe unique.

This ape tribe has become very famous.

In fact, this is not actually a tribe of apes. Since Ajie invented the knitting technique, has the ability to completely walk out of the cave, and uses fire to let her know how to eat cooked food, she can already be regarded as a civilized human being.

In addition, although Ajie invented weaving, her clan was never called Chu, let alone the Huaxu clan that only exists in mythology.

However, Ah Hui learned how to weave because of silk, so when the mistress found out about it, she called herself a silk tribe member.

The luck of the carbon poisoning incident did not make Zhang Jingtao feel at ease even for a second.

In my memory, although the Silk tribe truly gained a firm foothold at the tribal conference and no longer had to worry about migration, the following summer, continuous heavy rains caused flash floods.

Due to the improper mountain topography where the Silk Clan were located, just as Zhang Jingtao had worried before, the flash flood swept in from above the caves.

That terrible mudslide was absolutely irresistible.

Among the entire Silk tribe, only Ah Hui and Fu Xi thought of using rice dumpling leaves sandwiched in a two-layer bamboo net to make bamboo hats to protect themselves from the rain. They made bamboo hats by a small river far away, and they laughed and tried to use the big bamboo hats.

He only escaped death by leaving the cave far away.

The bamboo hat slipped from their hands, along with tears and rain.

In the wilderness, humans are so fragile.

Therefore, after something happened to the Silk tribe, they were called the Wolf tribe by the ape tribe in the Chu region.

It is said that the Silk tribe got too close to Xiaotian's wolf and was punished by heaven.

No matter if there is no Silk Clan, cold is the biggest punishment from heaven for them.

After that, it was the Straw Bag Clan who took in these two people from the Silk Clan. After all, where the Silk Clan’s previous achievements were, most of the Apes were still willing to take them in. The former mistress of the Straw Bag Clan also loved them very much.

, until a mudslide also occurred in the territory of the Grass Bag Clan, swallowing up the mistress who was out.

After the death of this mistress, the new mistress was very disgusted with the two of them, thinking that the Silk tribe had brought natural disasters to them. Therefore, there was a quarrel, but she wanted to drive away the two Silk tribesmen.

Zhang Jingtao frowned when he thought of this. Just as he was about to say something, a fat middle-aged woman across from him said with gestures: "We can't support more people here. Your tribe was swallowed up by the flash flood. That wilderness

There will be no output, and the cave will be gone. I think this is the retribution for your family being too close to the beasts."

Sure enough, it was the punishment that day.

Zhang Jingtao's expression condensed. It seems that when natural resources cannot support more people, those weak tribes who have become weak due to various reasons can only move north. After all, each tribe is in charge of its own family, too

After a long time, there was already an artificial distinction between near and far.
