Zhang Jingtao thought back to this, although these memories flashed quickly, he was still so nervous that cold sweat came out.

Just as death was about to come, fortunately, small animals were very sensitive to charcoal poison, and one sheep fainted first, and the rest of the sheep screamed.

Ah He and Fu Xi suddenly woke up, and they clearly felt that they had difficulty breathing, and hurriedly went to open the fence and woke up all the children.

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

And the vitality can make the fire burn more vigorously.

Moreover, this was discovered due to charcoal poisoning of a sheep, so if the sheep is alive, it means that there is vitality, so this vitality was later written as oxygen.

But in fact, oxygen is a fake word that does not have any other meaning except to express vitality, and it will make people unclear about the origin of sheep qi.

Living qi is called sheep qi.

For this reason, the water in which a woman conceives a child has always been called amniotic fluid, that is, water that has vitality.

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

Many people don't understand how the word fresh comes from, so foodies think that it is fish and sheep stewed together that is fresh, however, in fact, the taste is not more delicious than simple stewed fish or stewed sheep.

But after knowing that the sheep represents vitality, you will know that freshness, in fact, is just a 'live fish'.

Dead gas, on the other hand, is called charcoal gas, which fully expresses the characteristics of fire-using civilization that incomplete combustion will produce dead gas.

It was only after this important experience that Ah's people truly understood fire.

Of course, knowing is not the same as being in control.

When the people of the Silk Clan came back, they all had sad faces.

After all, they have all felt the benefits of fire, but the danger of fire seems to be impossible to completely prevent.

"Maybe we can open more holes." Ahh said.

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

They went to see the small hole that was used as a ventilator for the fire.

At this glance, the two of them were pleasantly surprised, because the little hole was so hot, if they didn't get close to the wall behind the fire, it would be fine, if they were close, they would immediately think of baking cookies.

So is it possible to move the fire into this hole and bake the main hole next door as a biscuit?

Of course.

After this method was created, the Silk people were happy, and the fire was isolated, which was so safe that it couldn't be safer.

Everyone took Erha and started digging a hole again, this time to open a ventilation hole for the new fire hole, and open a fire hole.

Such a fire is not afraid of dead air at all, and the hole of this hole can be basically closed according to the method that incomplete burning charcoal can prolong the burning time, so that the fire burns very slowly and saves materials.

This material-saving approach comes from the use of carbon.

And, Ah He opened a hole between the fire cave and the fire hole.

In this way, when the weather is good, you can take some of the fire stored in the storage hole and place it in the fire hole, so that the fire will not be affected when it rains.

Sure enough, with the help of the mountain wall, the heating of the main cave is not a problem at all, this is almost the use of the fireplace, but the conditions of the ape-man are better than that of foreigners, and the fireplace can be completed with four holes, so this usage is very safe.

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

And foreigners who are not civilized, but in modern times, they will only use very dangerous fireplaces, which will be so, a scroll in the Privy Council called "The Age of Hellfire" is slightly recorded.

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

But it is conceivable that the method of separating people from fire for heating more than 200 million years ago is really super advanced.

have surpassed modern foreigners.

For this reason, the cave of the Silk people became extremely comfortable, and even the kitchen was separated.

Since then, there is no doubt that the use of fire, weaving, captive beasts, and some compound pronunciations of the nouns have also made this group unique.

This ape clan became very famous.

Even, this is not actually an ape, because Ah Ah invented the art of weaving, has the ability to completely get out of the cave, and the use of fire has taught her to eat cooked food, therefore, she can already be regarded as a civilized human.

In addition, although weaving was invented by Ah He, her clan was never called Chu, let alone the mythical Huaxu clan.

But it was Ah He who learned to weave because of silk, so after the master mother found out, she called herself a silk clan.

And the luck of the charcoal poisoning incident did not make Zhang Jingtao feel at ease for even 1 second.

In my memory, although the Silk tribe really gained a foothold at the tribal assembly and no longer had to worry about migration, however, in the summer of the following year, continuous heavy rains caused flash floods.

Due to the mountainous terrain where the Silk Clan was located, as Zhang Jingtao had worried before, and inappropriately, the torrent swept from above the cave group.

The terrible mudslide was irresistible.

In the entire silk clan, only Ah He and Fu Xi were spared because they thought of using zongzi leaves to make a hat in a two-layer bamboo net to avoid the rain, and made a hat by a small river far away, and tried the role of a big bamboo hat with a big bamboo hat, far away from the cave.

The bamboo hat slipped from the hands of the two, with tears and rain.

In the wilderness, human beings are so vulnerable.

As a result, after the accident of the Silk Clan, they were called the Wolf Clan by the ape clan in Chudi.

It was said that the Silk Clan and the wolf of the Howling Sky got too close and were punished by heaven.

Regardless of the Ruwu Silk Clan, the cold is the greatest punishment for them.

After that, it was the straw bag clan that took in the two people of the silk clan, after all, the previous exploits of the silk clan were placed there, and most of the ape clan were still willing to take in the two, and the former master mother of the straw bag clan was also, and she loved the two very much, until the boundary of the straw bag clan, there was also a mudslide, which was engulfing the housemother who went out.

After the death of the housewife, the new housewife was very disgusted with the two, thinking that it was the Silk people who brought them natural disasters.

Zhang Jingtao thought of this, frowned, and was about to say something, when a very fat middle-aged woman on the opposite side said with a gesture: "There are no more people here, your tribe was swallowed up by the torrent, and that field will have no output, and the cave will be gone, I think, this is the retribution for your clan and the beast being too close." ”

Sure enough, it was the punishment of the day.

Zhang Jingtao's expression froze, it seems that when natural resources can't support more people, those weak tribes who have become weak for various reasons can only move north, after all, each tribe has its own family, and after too long, there is already an artificial distinction between far and near.

In the flood wilderness, if there is a conflict between the tribes, there will naturally be a fierce war.
