Drilling wood for fire first originated in China, using the principle of friction heat generation to make fire.

When drilling wood, put hay and sawdust flammable materials around the wood drilling hole, a lot of heat will be generated when rubbing, and when the heat accumulates to a certain extent, there will be light smoke coming out.

Zhu Ping'an understands all these truths, but when he really practiced making fire, Zhu Ping'an found that it was really difficult to drill wood to make fire.

Zhu Ping'an rubbed the wooden stick with both hands, very hard, but the little girl with the bun on the side looked at the eyes sour, Zhu Ping'an couldn't take out the fire, but it hurt from the grinding of his hands.

But it's not without effect, at least the wood feels hot.

Seeing that drilling wood is so simple, the little girl with buns also came up to join in the fun, but it is not as good as Zhu Ping'an, she is panting again and again, and the frequency of rubbing is much lower, so naturally she can't make a fire.

Li Shu also tried, but also failed.

"Uncle, what should I do?" The little girl raised her head, bit her lip, looked at Zhu Ping'an pitifully and asked.

Zhu Ping'an thought for a moment, the crux of the reason why the three of them failed to take out the fire was that the frequency of rubbing the wooden stick was too low, and the heat generated could not reach the ignition point of the hay and wood, so they failed to take out the fire.

Finding the crux of the problem, Zhu Ping'an thought about how to increase the frequency of rubbing the wooden stick, and then Zhu Ping'an thought of the bowstring. To make a simple bow, twist the bowstring on the stick, and then pull the bow quickly to drive the stick to spin at high speed.

"There's a way." After coming up with a solution, Zhu Ping'an slightly hooked the corners of his lips.

looked at the curvature of the corners of Zhu Ping'an's lips. The corners of Li Shu's eyebrows and eyes are full of moving charm, and a pair of watery eyes are about to drip water, no matter what the problem is, it can't help him.

The little girl with the bun was a little skeptical. She didn't suspect Zhu Ping'an, but suspected that this Lao Shizi drilled wood for fire, drilled wood for fire? It's a bit unreliable to listen to.

In the eyes of the two girls, Zhu Ping'an went to the stream and broke another branch, then tore off a strip of fine cloth from his clothes and tied it to the branch to make a simple bowstring.

From the side of the stream, he saw a small piece of stone with a groove, and brought it with him, and wound the bowstring around the stick. Press the stick with a grooved stone, place the stick in the small hole in the wood underneath, and then start pulling the bow.

The bow body drives the bowstring. Then he ran at high speed with a wooden stick, dozens of times faster than Zhu Ping'an rubbed it by hand.

Hmm

The sound of rubbing is endless.

Simple repetitive pulling is very boring, but drilling wood for fire is to endure this boredom. And. Often success is like this. You have to endure loneliness and boredom to succeed.

The little girl with the bun held her chin and looked at Zhu Ping'an, and began to nod and doze off

I don't know how long it took, Zhu Ping'an saw a wisp of light smoke gradually rising from the borehole, which was almost invisible, but it was really smoking.

"It's smoking." The corners of Li Shu's eyes narrowed.

"Ah, it's really smoking, it's smoking," the little girl with the bun heard her own lady say in a daze. Then he raised his head, and then he saw that the wood under Zhu Ping'an's men began to smoke. Then a spirit burst into action.

After the smoke, Zhu Ping'an struck while the iron was hot and continued to pull the bowstring.

Li Shu walked over at this moment, squatted down, puffed out her mouth, and slowly blew up.

When Li Shu started blowing, Zhu Ping'an still wanted to stop Li Shu, lest this eldest lady with ten fingers not touching the spring water blow out the sparks that she had managed to drill out, you must know that blowing fire is a technical job, blowing the fire in a hurry, blowing small is not useful, it has to be just right, Zhu Ping'an also followed his mother Chen for a long time to master.

However, before Zhu Ping'an could stop it, Li Shu had already blown it.

Moreover, Li Shu's boasting was unexpectedly good for Zhu Ping'an, if it weren't for Li Shu being a wealthy lady of the world, Zhu Ping'an would have thought that Li Shu was a pretty cook with several years of cooking experience.

This blow is really just right, it is estimated that Zhu Ping'an can't blow this effect by himself.

This girl is really a demon, the first time she blows fire, she can have such a wise root, Zhu Ping'an secretly sighed in her heart when she drilled wood, this girl is really blessed.

With the assistance of Li Shu, Zhu Ping'an's drilling wood for fire went a lot smoother, the green smoke came out more and more, the rich green smoke was like a fairy coming out, and soon a handful of flames rose, Zhu Ping'an slowly took out the wooden stick, Li Shu blew gently, and the flames burned.

The fire was transferred to the stone stove in time, and the hay was placed to ignite the fire, and the fire grew larger, and the slightly damp hay was put into it, followed by the firewood that was picked up.

The flames were very angry, and the fire under the stove was very strong.

I don't know if it's curiosity or some kind of play, Li Shu broke a branch as a long chopstick, cleaned it in the clear stream, and began to cook fish soup.

It's all there

Forget it, Zhu Ping'an smiled indifferently, just let Li Shu toss, anyway, no matter how bad the fish soup is, it is still fish soup, and I won't pick my mouth if I have been hungry for so long, so let's satisfy the interest of this eldest lady.

Later, if it is really unpleasant, fill your stomach and drink less.

After Zhu Ping'an made up his mind, he went to the vicinity of the stream to find out if there were anything else that could fill his stomach, such as wild fruits or something.

did not disappoint Zhu Ping'an, Zhu Ping'an looked for a while and found a cluster of red wild strawberries in a bush, which was smaller than modern strawberries, about the size of a quail egg. This kind of wild strawberry, Zhu Ping'an used to pick it in the mountains with his father and brother, and it tasted quite delicious.

Oh, by the way, it is the famous "raspberry" written by Mr. Lu Xun, but the people of Xiahe Village are used to calling it "Mencius", which is actually the abbreviation of Shumeng, Meng, Changye, Shumeng as the name suggests is the fruit that grows on the tree.

Zhu Ping'an picked the ripe ones of the wild strawberries in this cluster, and left the unripe ones on the plants, almost more than 30 of them. After picking it off, Zhu Ping'an washed it in the stream, picked it up with his clothes and returned to the original stream.

When Zhu Ping'an returned, Li Shu had already prepared the fresh fish soup, and before he could get there, he smelled an attractive fresh aroma of fish soup.

How fragrant is it?

It's probably because I'm hungry, Zhu Ping'an smiled self-deprecatingly, Li Shu, the eldest lady who doesn't touch the spring water with her fingers, is on a whim, how can it be so fragrant when making fish soup for the first time. (To be continued.) )
