Moreover, there is a beautiful legend about drilling wood for fire.

In ancient times, there were many white stones on Kunlun Mountain, where the white stones accumulated, there was little grass and trees, and the only tree that could grow on the stone was called flint. Fusilier has a characteristic of having only stems, no bark, branches, and no leaves. It looks like a dry tree, and you can look at its branches as leaves. Branches fall every year and regenerate the following year.

But at this time, no one said, "When I see a piece of wood, I will go up and drill it to see if it will catch fire, and ordinary people, including Jiang Liu'er, who is also a primitive man, would not have such intentions."

But one day, a bird came to Kunlun Mountain, and later generations called her Bi Fang, Bi Fang, a bird that has a habit, it has a particularly sharp beak and likes to peck at the wood. Turning wood to make fire is actually pecking wood to make fire, and when the wood is pecked, the tree actually makes a fire.

After the fire, these flint clansmen looked at the fire, so that they could also catch fire. As soon as they were gone, they tried to drill other flints to see if they could catch fire. Later, they used the method of grinding inside, and tried their best to think of it, and finally succeeded, turning wood to make fire.

Of course, after this drilling wood for fire, people were limited to one kind of wood, that is, flint, and used it to make fire. But after the flint made fire, we say that after the flint clan drilled wood to make fire, because of the advent of that catastrophe, when they later moved down from Kunlun Mountain and moved to Sun Moon Mountain, this original wood no longer existed. So drilling wood for fire is just a very distant legend of ours, and people try their best to drill wood to make fire.

For a long time, I knew that it was very hard to drill wood for fire. We have to find ways to pick all kinds of wood and drill it in different ways. What kind of wood do you choose? In the spring, willow is used, jujube and apricot are used in summer, and oak is used in autumn, and different woods are used to ensure the success of drilling wood for fire.

Of course, while drilling wood to make fire, the wise ancestors of China found that there was another way to make fire.

Knock a bucket into a semi-oval, keep it smooth, polish it smooth, the smoother the better, concave inside, facing the sun, that piece is placed with firewood and grass, so that it will shine on it, Jiang Liuer probably guessed, just like the magnifying glass in contemporary times, to make fire when it shines.

When there is a sun, use a firebrush to make fire, and when there is no sun, use a wooden flint to make fire. But it is actually very difficult to make fire from wooden flint.

At the end of the day, a big man who didn't know the name found a flint, and the flint was not made by the flint itself, but something like electricity underneath, and we called it a fire wheel, and as long as there was a spark splashing on it, it immediately caught fire. In modern times, there were fire sickles and flints, but one of the most obvious features was how to store fire.

In the earliest days, just like all people think, in fact, you don't have to store it deliberately, because your race is in the cave, and the fire will never be extinguished, but this is not a long-term solution, they want to migrate, and the process of migration invented clay, the clay is kneaded with mud, and the loess is harmonized, and after the completion of the fire, the fire is directly placed in it, and the surrounding is burned hard to prevent it from cracking.

Later, in order to prevent cracking, it was placed in a dry place, and there were two holes in it, which was similar to our current honeycomb coal stove, just a honeycomb coal stove made of clay. When the wood is halfway burned, put it in it, and then cover it, leaving two eyes, which is actually what we call charcoal now, and use charcoal to preserve the fire. It's the clay of the past.

This method has been used for a long time, until later people came out of the Sun Moon Mountain, and when they came back, there was a simpler way, there was a kind of grass called Artemisia white in the Weihe River Basin, more than one meter long, pull this grass down after it grew into adulthood, two on each side, a total of six grasses, braided together, about two meters long, after drying, put there all year round, they want to live, they want to go somewhere else, when everyone wants to do different things, just take a mugwort, take a mugwort on the road, it will not be extinguished.

When he got to that place, he picked up some firewood, and when he blew it, the fire was lit.

The greatest contribution of the Suiren clan to people can be said to be the first time that human beings have realized that they can create fire by themselves, and the inspiration for creating fire comes from a bird called Bi Fang, which comes from flint.

Therefore, this clan was named after the flint, and later generations called him the flint clan. But this Suiren clan finally merged with another ethnic group on the Kunlun Mountains and merged into a clan, this clan is called the Qiang tribe, Jiang Liuer clearly remembers that this ethnic group still existed until the 21st century.

Later, the Suiren clan disappeared, but the Qiang always existed.

……

But legends are legends after all, and the origin of drilling wood for fire has long been unexaminable, but Jiang Liuer has seen the drama of drilling wood for fire more than once on the wilderness survival broadcast on contemporary TV.

Whether it is Bei Ye's wilderness survival, or a husband and wife who are a husband and wife in the wilderness, or vaguely remembering that an Englishman who didn't even wear pants survived in the wilderness for forty days, or the Australian brother's empty-handed brick-burning house, there are scenes of drilling wood to make fire.

This at least shows that although the techniques left by the ancestors are primitive, they are in some special occasions, such as when they need fire.

Like now.

The rain was still falling outside, and God seemed to be angry with someone, looking angry, pouring out his anger - pouring heavy rain, lightning and thunder.

The light inside the cave is getting dimmer and dimmer, but from time to time, dazzling lightning will streak across the sky, and it can also illuminate the cave where Jiang Liu'er is located in an instant.

Following the dim light, Jiang Liu'er found some branches that had fallen in the cave for some reason, some thick and some thin.

Generally speaking, the fire pole used to drill wood for fire should be made of fast-growing softwood, but now is an extraordinary time, it is raining so heavily outside, and the sky is getting dark, so you can only use a dead horse as a live horse doctor.

Jiang Liuer first chose a piece of wood about a foot long, which was embedded with a fingernail compared to other woods, which felt relatively soft, about three inches wide and one inch thick, as a fire pole.

Drilling the stalk is relatively hard, and it is relatively straight, not particularly thick wooden sticks, and Jiang Liuer can only find a hardwood stick that can barely be used.

Because the drill stalk is too long, only a part of it can be truncated.

With a "click", Jiang Liu'er held the two ends of the drill stalk with both hands, and hit it with his kneecap, and the wooden stick broke in response to the sound and was divided into two pieces of about the same size.
