Of course, Han Cheng was not happy, his purpose was to find a way to raise a fire quickly, using these two stones to make a fire was slower than drilling wood to make a fire, so even if he proved that he could use stones to make a fire, what was the point?

The next day, Han Cheng no longer looked for stones, but tried to make fire folds.

If there is no bamboo tube, it will be replaced by a bone stick, and if there is no yellow paper, it will be replaced by the velvet when the fire is ignited.

Han Cheng brought it to the burning fire and lit it, then blew out the flame, letting it burn in a dark flame, but it didn't take long for the dark flame to be extinguished.

Han Cheng used a thinner stick to poke out the velvet filled inside the bone stick, and thought about it for a while, thinking that maybe he had stuffed the velvet too porcelain, so the velvet burned and was extinguished not long after.

When it is filled again, it is not as dense as the top.

Tuck one end of the stick tightly and go to the fire again to light it.

Sure enough, this time the fire velvet was not extinguished, but it burned very quickly, Han Cheng estimated that in less than half an hour, this section of about fifteen centimeters of fire folds was all burned......

Han Cheng then adjusted the tightness of the velvet, and after finding that the velvet used to ignite the fire was not enough to meet the demand, he began to try other materials.

It is said that Edison experimented with more than 1,000 materials in order to invent the electric light, and finally succeeded, and now Han has become a fire breaker, and he has tried dozens of materials, but the result is still unsuccessful.

So far, the fire fold he has made has not been extinguished, and the longest one has not survived a morning......

However, such a fire fold can also be used, in the past, if the dead or Heiwa and others wanted to start a fire in the quarry or clay kiln, the only way they could do it was to fill some coals in a clay pot from the big fire in the cave or take one or two burning firewood and walk away quickly, for fear that these flames would be extinguished if they were delayed for too long.

Some times when you're unlucky, you need to make two or three trips to get the firewood on fire.

Now that they have this fire that can burn for a long time, when they light the fire outside, they are much calmer.

When the people of the Qingque tribe were deeply impressed by the wisdom of the Divine Son, Han Shenzi frowned slightly and looked dissatisfied.

This kind of fire is still too far from what he imagined, he needs to be the kind that can at least continue to burn all night without extinguishing, only in this way can he rest assured and boldly extinguish the pair of fires that keep burning day and night......

A small fire break, this time it really stumped Han Cheng, he stayed in the cave**, thinking of a solution......

Fu Jiang, who had been in the cave for too long, bit the small leather skirt around Han Cheng's waist with his teeth, pouting his ass and pulling hard.

It wanted to drag its stupid owner out and play outside.

But he didn't pay attention to the force and pulled off the short skirt around Han Cheng's waist.

At the same time that Han Cheng walked away, Fu Jiang, who was holding a leather skirt in his mouth, also took several steps back.

"Ahh

Of course, this is not called by Fu Jiang, a guy who is becoming more and more like Erha, otherwise wouldn't he have become a sperm?

The limp limped in from the outside, came to the place near the inner hole to take the hand pressure drill, ready to make a hole, saw Miko sitting there and pondered and did not dare to disturb, took the hand pressure drill and walked out lightly and carefully.

As a result, he didn't take two steps, and Fu Jiang made this move.

The lame legs and feet were not very good, and they were tripped by the blessing general who suddenly came to their feet, and they fell to the ground if they couldn't control it.

Fu flashed this guy fast, and he was not hit by the lame, but the lame fell firmly.

This oop came from the mouth of a lame.

limped and fell to the ground, not caring about his injury, but hurriedly picking up the hand pressure drill on the side that was falling.

The floor of the cave is a stone bottom, and the somewhat thin stone drill bit just hits the stone and breaks in the middle.

This made the limp feel unusually sorry.

Because this hand pressure drill is the most convenient to use.

He was a little annoyed for a while, and wanted to hit the lucky general, but when he turned his head and saw this guy wearing a short skirt of Miko's skin, he couldn't help laughing.

Han Cheng naturally had no way to ponder at this time, he was busy coming over to help the lame up, but the lame had already stood up by himself, holding the broken drill bit in his hand, looking very pity.

Han Cheng saw that the lame was fine, so he turned his head and glared angrily at Fu Jiang's stupid dog.

Fu Jiang also felt that he was in trouble, his tail drooped down, and he looked a little timid and took the leather skirt in his mouth to Han Cheng's hand and rubbed it on Han Cheng's hand.

Han Cheng slapped it twice on the head, took the leather skirt and went to the waist, this guy rolled his eyes and quietly looked at Han Cheng twice, seized the opportunity, quickly turned around, spread his four legs, and ran out of the cave, for fear that if he ran slowly, he would be kicked on his buttocks.

Han Cheng was amused, laughed and scolded, looked at the broken stone drill bit in the lame, and felt a pity, after all, it was not too easy to polish a drill bit.

Just as he was about to instruct the limp to use another hand to press the drill first, and this one would be repaired later, when a light suddenly crossed his mind.

Surrounded the leather skirt three or two, and said, "Give me this, you use something else." ”

Before he finished speaking, the broken hand pressure drill in the lame's hand had already been transferred to Han Cheng's hand.

Miko has come up with a good idea again?

Limply looking at Shenzi who was rushing away, thinking so in his heart, he took another drill bit and gave Fang Cai's hand-pressed drill of about the same size, and he didn't care about patting the dust on his body, so he hurriedly went to catch Shenzi, wanting to see what different miracles Shenzi could make with the pressure drill he was already familiar with.

Han Cheng found that after the fire of the Qingque tribe was occasionally extinguished, he used two pieces of wood for drilling wood for fire, and saw that it was too big, so he went outside the tribe to look for branches again.

You can't use that kind of hard wood for fire, because it is not easy for soft, drilled wood chips to fall off from it.

Poplars, paulownia trees and other fast-growing trees are good for drilling wood for fire.

Han Cheng found a fluffy branch about two centimeters in diameter, two meters long, and took it back to the courtyard.

From the middle of the section, two sections, in the thicker section near the top, mark a point, so that the lame standing on the sidelines can drill a pit with the hand pressure drill in his hand.

The pit doesn't need to be too deep, just drill the wood halfway through.

While limp drilling, Han Cheng was also quickly handling another piece of wooden stick.

One end is slightly polished and smooth, and then a wooden groove is carved out with a stone knife on the other head to clamp the rope, and then the wooden rod made according to the specifications of the drill pipe is wound around two ropes and mounted on a hand-pressed drill.

At this time, the lame also drilled the pit.

Han Cheng took it and looked at it, and used the thin stone chips in his hand, which could be called stone knives, to carve two grooves on the left and right sides of the wooden pit, so that the tools for drilling wood for fire that were much lighter than the original ones of the tribe were also made.

Han Cheng found a ball of velvet for ignition, which was made from a kind of leaf.

When you rub this dried leaf in your hand, a lot of tiny 'silks' will come out, and it is very good to use it to start a fire.

However, this tree is not the kind of eucommia tree seen in later generations, the leaves of the eucommia tree Han Cheng did not play with it less when he was a child, and he can recognize the big difference between the two.

So this kind of tree, which Han Cheng had never seen before, had a gorgeous name - the edelweiss tree.

(This afternoon on the most awesome recommendation ever, the collection of an hour of a hundred rises, too exciting, the old street music fainted in the toilet...... Book friends have read it and then throw me two recommendation tickets, happy and happy, adding fuel to the fire, even if I am dizzy in the toilet for a night, I am also willing to do everything to ask for tickets)
