I am a Primitive Man

Of course Han Cheng is not happy. His purpose is to find a way to start a fire quickly. Using these two stones to make a fire is slower than drilling wood. Then even if he proves that a fire can be made with a stone, How significant is it?

　　 On the next day, Han Cheng stopped looking for stones, but tried to make fire folds.

　　 If there is no bamboo tube, use the bone stick instead, and if there is no yellow paper, use the tinder for ignition. After a long time of tinkering, I finally created a big change in appearance.

　　 Han Cheng put it on the side of the burning fire and lit one end, then blew out the flame and let it burn as a dark fire, but the dark fire was extinguished before long.

　　 Han Cheng used a thinner stick to stoke out the tinder filled in the bone rod. After thinking about it, he thought that he might have stuffed the tinder too much, so the tinder burned out before long.

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

　　 After stuffing one end of the bone stick tightly, he moved to the fire again and set it alight.

Sure enough, the tinder was not extinguished this time, but it burned very quickly. Han Cheng estimated that in less than half an hour, this section was about 15 centimeters long and burned completely... …

　　 Han Cheng then adjusted the tightness of the tinder, and later found that the tinder used to ignite the fire was not enough to meet the demand, so he started experimenting with other materials.

　　 It is said that Edison fully experimented with more than a thousand materials in order to invent the electric light, and finally succeeded. Now Han has become a maker of fire folds, and he tried dozens of materials, but the result was still unsuccessful.

　　So far, he has created the fire folds to preserve the fire and not extinguish, and the longest one has not survived a morning...

However, this kind of fire fold can also be used. In the past, people like Shang or Heiwa who wanted to start a fire in a quarry or earthen kiln could only use it from the fire in the cave*. Put some hot coals in the clay pot or take one or two burning woods and walk away quickly, for fear that the flames will go out after too long a delay.

　　 When I have some bad luck, I need to run two or three times to burn the firewood there.

　　 Now that they have this long-lasting fire fold, when they light a fire outside, they calm down a lot.

　　 When the people of the Qingque tribe deeply admired the wisdom of the **** son, the **** son Han frowned slightly and looked dissatisfied.

This kind of fire book is still too far from what he imagined. He needs to be the kind that can continue to burn all night without going out. Only in this way can he safely and boldly make the cave that keeps burning day and night. Off...

　　 A little Huozhezi, this time really stumped Han Cheng, he stayed in the cave, dreaming of a solution...

　　 Fu Jiang, who had been in the hole for too long, bit the small leather skirt around Han Cheng's waist with his teeth, and pulled his **** forcefully.

　　 It wants to drag its already stupid master out to play outside.

　　 but inadvertently used too much force and tore off Han Cheng's short skirt around his waist.

　　While Han Cheng was gone, Fu Jiang, who was holding his leather skirt in his mouth, also took a few steps back.

　　 "Oh oh!"

　　 Of course, this is not what Fu Jiang called this guy who is more and more like Erha, otherwise, wouldn't it be a fine?

He walked in limply from the outside, came to a place near the inner hole to pick up a hand drill, ready to punch a hole, seeing the **** child sitting there concentrating and not daring to bother, taking the hand pressure drill lightly Walk out carefully with your feet.

　　 After two steps, Fu Jiang made the noise.

　　'S lame leg was not so good when the script came. When Fu Jiang who suddenly came to his feet tripped like this, one fell to the ground because he couldn't control it.

　　Fu flashed this guy quickly, without being hit by the limp, but fell firmly with the limp.

　　 This ouch came from a lame mouth.

　　 fell to the ground limp, not caring about his injuries, but hurriedly picking up the hand-pressed drill on the side of the fall.

　　 The ground of the cave is a stone bottom, and the thin stone drill bit just hit the stone and broke in the middle.

　　 This makes lame feel very pity.

　　Because this handle drill is the most convenient one to use.

　　 He was a little annoyed for a while, and wanted to hit the lucky general. He turned his head and saw the funny appearance of this guy wearing a divine leather skirt, and couldn't help laughing.

　　 Han Cheng naturally had no way to meditate at this time. He was busy coming over to help him up, and he had already stood up by himself, holding the hand drill with the broken bit in his hand, looking like a great pity.

　　 Seeing that he was lame, Han Cheng turned his head and glared at the silly dog ​​Fu Jiang.

　　Fu Jiang also felt that he had made trouble, his tail drooped, and he looked a little timidly and took the leather skirt from his mouth to Han Cheng's hand and rubbed it against Han Cheng's hand.

Han Cheng slapped it twice on the head and took the leather skirt to the waist. This guy rolled his eyes and looked at Han Cheng quietly. Taking the opportunity, he quickly turned around, spread his four legs, and went out of the cave. Run, for fear that you will get a foot on your **** if you run slowly.

　　 Han Cheng was amused and scolded. He looked at the broken stone drill bit in his lame hand. It was a pity. After all, it is not too easy to polish a drill bit.

　　 was about to instruct Lame to use another hand to press the drill, this will wait and then repair, a light suddenly flashed through his mind.

　　 surrounded the leather skirt in twos and then said: "Give me this, you use something else."

　　 Before he finished speaking, the broken hand drill in his lame hand was transferred to Han Cheng.

　　 God child came up with a good idea again?

Looking at the **** child who left happily, thinking like this in his heart, he took another drill bit to the hand-pressed drill of the same size just now. The dust on his body couldn't care about it, so he hurried to catch the **** child, wanting See what different miracles the **** child can do with the pressure drill he already knows.

　　 After Han Cheng found the Qingque tribe’s fire that was occasionally extinguished, the two pieces of wood used for emergency rescue were used to drill logs to make fire. He found that he was too big, so he went outside the tribe to search for branches.

　　The hard wood should not be used for drilling wood to make fire, because it is not easy to have soft, hot, sparked sawdust from the top.

These fast-growing trees, such as poplar and paulownia, are good for drilling wood to make fire~www.wuxiahere.com~ Han Cheng found a soft branch about two centimeters in diameter and two meters long. Take it back to the courtyard.

　　 One two sections from the middle, mark a point on the thicker section near the top, so that the one who is standing aside is lame, and drills a hole with the hand drill in his hand.

　　The pit does not need to be too deep, just drill the wood halfway up.

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

Polish one end slightly to make it smoother, and then use a stone knife to carve out a wooden groove for holding the rope on the other end, and then wind the wooden rod made according to the specifications of the drill pipe with two loops of rope. Mounted on the hand drill.

　　 At this time, the lame has also drilled the hole.

Han Cheng took a look, and he carved two grooves on the left and right sides of the wooden pit with a thin piece of stone that could be called a stone knife in his hand. This is lighter than the tribe’s original tools for drilling wood and making fire. It's done.

　　 Han Cheng found a bunch of tinder, which was made from a kind of leaf.

　　 Put this kind of dried leaves in your hand and knead it, and there will be a lot of tiny "silks" coming out, which is good to start a fire.

　　 But this tree is not the kind of eucommia tree seen in later generations. The leaves of the eucommia tree Han Cheng played with him when he was a child, and he can recognize the big difference between the two.

　　 So this kind of tree that Han Cheng has never seen before, has a gorgeous name-tinder tree.

(This afternoon I went to the best recommendation I have ever received. The collection is 100% in an hour. It’s too exciting. The old street is fainted in the toilet... The book friends have seen it and then throw my two recommendation tickets. Well, I’m happy, I’ll add fuel to the fire, even if I faint in the toilet all night, I’m willing to do everything-in order to ask for a ticket, I will do everything in my mind)
