Chapter four hundred and eighty fifth island survival (seven)
Drilling wood to make fire first originated in China, which uses the principle of frictional heat to make fire.`
When drilling wood, place flammable materials such as hay and sawdust around the hole in the wood. A large amount of heat will be generated during friction. When the heat accumulates to a certain extent, light smoke will come out. At this time, gently touch the place where the smoke originates.
Blow into the air to introduce combustion-supporting oxygen, and flammable materials such as hay and sawdust can create a fire.
Zhu Pingan understood all these principles, but when he actually practiced making fire, Zhu Pingan realized that it was really difficult to drill wood to make fire.
Zhu Pingan rubbed the wooden stick with both hands, working very hard, but the eyes of the little maid with steamed buns on the side were sore. Zhu Pingan couldn't take out the fire, but it hurt from grinding his hands.
But it's not ineffective, at least the wood feels hot.
Seeing how easy it was to drill wood, Baozi's little maid also came up to join in the fun, but she was not as good as Zhu Ping'an. She was gasping for breath, the frequency of rubbing was much lower, and naturally she couldn't make a fire.
Li Shu also tried it, but failed.
"Uncle, what should I do?" The little maid Baozi raised her head, bit her lip, and looked at Zhu Pingan pitifully and asked.
Zhu Pingan thought for a moment. The crux of the reason why the three of them could not get out the fire by drilling the wood was that the frequency of rubbing the sticks was too low. The heat generated could not reach the ignition point of hay and wood, so they could not get out the fire.
.`
After finding the crux of the problem, Zhu Pingan thought about how to increase the frequency of rubbing the wooden stick. Then Zhu Pingan thought of the bow string. Make a simple bow, twist the bow string on the wooden stick, and then quickly pull the bow.
The stick spun high.
"There is a way." After coming up with a way, Zhu Ping'an raised the corners of his lips slightly.
Looking at the curvature of the corners of Zhu Pingan's lips, Li Shu's brows and eyes were filled with a charming charm, and his watery eyes were about to drip. No matter what the problem was, he could not be troubled.
The little maid Baozi was a little suspicious. She didn't doubt Zhu Ping'an, but she doubted this Lao Shizi's method of drilling wood to make fire, drilling wood to make fire? It sounded a bit unreliable no matter what.
Under the gaze of the two girls, Zhu Ping'an went to the stream and folded another branch. Then he tore off a piece of fine cloth from his clothes and tied it to the branch to make a simple bowstring.
I brought a small piece of grooved stone from the stream and brought it over. I wound the bowstring around the stick, pressed the grooved stone on the stick, and placed the stick in the small hole in the wood below. Then we started.
Pull the bow.
The bow body drives the bow string, and then wraps it around the wooden stick and rotates it dozens of times faster than Zhu Pingan can rub it with his hands.
Uh-huh
The sound of friction is endless.`
Simply pulling and pulling repeatedly is very boring, but drilling wood to make fire means to be able to endure this boredom. Moreover, success is often like this. Only by enduring loneliness and boredom can we succeed.
The little maid Baozi held her chin while watching Zhu Ping'an drilling the wood, and she began to nod off and doze off.
He drilled and drilled for an unknown amount of time before Zhu Pingan saw a wisp of light smoke gradually rising from the drill hole. It was almost invisible, but it was real smoke.
"There's smoke." Li Shu narrowed her eyes.
"Ah, it's really smoking, it's smoking." The little maid Baozi heard her lady say "smoking" in a daze, and then she raised her head. Then she saw the wood under Zhu Ping'an's hand starting to smoke.
, then he got excited and jumped for joy.
After the smoke came out, Zhu Pingan struck while the iron was hot and continued to draw the bowstring.
Li Shu came over at this moment, squatted down, puffed up her small mouth, and blew slowly.
When Li Shu started blowing, Zhu Ping'an wanted to stop Li Shu, lest this young lady, who had no fingers in the air, would blow out the sparks she had managed to get out. You must know that blowing fire is a technical job.
If you blow too hard, the fire will go out. If you blow too small, it won't work. You have to blow it just right. Zhu Ping'an also mastered it after playing with his mother Chen for a long time.
However, before Zhu Ping'an could stop him, Li Shu had already blown it.
Moreover, Li Shu's performance was beyond Zhu Pingan's expectation. If Li Shu was not the eldest lady of a wealthy family, Zhu Pingan would have thought that Li Shu was a pretty cook with several years of cooking experience.
This blowing is really just right. I don’t think Zhu Pingan could even blow it by himself to achieve this effect.
This girl is really a monster. She has such wisdom even when she blows fire for the first time. When Zhu Pingan drilled the wood, he secretly sighed in his heart, this girl is really blessed.
With the help of Li Shu, Zhu Pingan's drilling of wood to make a fire went much more smoothly. More and more green smoke was coming out. The thick green smoke was like a god coming out. Soon a handful of flames rose up. Zhu Pingan slowly
Slowly taking out the wooden stick, Li Shu blew it gently, and the fire started to burn.
The fire was moved under the stone stove in time, and hay was put on it to ignite the fire. The fire gradually grew bigger, and slightly damp hay was put in, followed by the collected firewood.
The fire is very lively, and the fire under the stove is very strong.
Out of curiosity or some sense of fun, Li Shu broke off a section of a branch to use as long chopsticks, washed them in the clear stream, and started cooking fish soup.
Pretend to be presentable
Forget it, Zhu Ping'an smiled nonchalantly and let Li Shu do it. Anyway, fish soup is still fish soup no matter how bad it tastes. After being hungry for so long, he will not be picky. This will satisfy the eldest lady's play.
Be interested.
If it tastes really bad later, just fill your stomach and drink less.
After Zhu Ping'an made up his mind, he went to the stream to see if there were any other things that could fill his stomach, such as wild fruits or something. This kind of water source environment should be rich in products.
Zhu Pingan was not disappointed. After searching for a while, Zhu Pingan found a cluster of red wild strawberries in a bush. They were smaller than modern strawberries and about the size of a quail egg. This kind of wild strawberry was what Zhu Pingan used to know.
My father and brother picked it in the mountains and it tasted quite delicious.
Oh, by the way, it is the famous "raspberry" written by Mr. Lu Xun, but people in Xiahe Village are used to calling it "Mencius", which is actually the abbreviation of Shumeng. Meng means long. Shumeng, as the name suggests, grows on trees.
fruit.
Zhu Pingan picked the ripe ones from the bunch of wild strawberries and left the unripe ones on the plant. He picked more than thirty of them. After picking them, Zhu Pingan washed them in the stream and carried them in his clothes.
Return to the original stream.
When Zhu Ping'an returned, Li Shu had already prepared fresh fish soup. Before he walked there, he smelled an alluring aroma of fish soup.
It smells so good?
Probably because he was starving, Zhu Ping'an laughed to himself. Li Shu, a young lady who never touched Yang Chun Shui, had a whim. How could it be that the fish soup tasted so good when she made it for the first time?
