I am a Primitive Man

　　 The heavy snow covered the field, seeming to seal everything up, and the whole world seemed extremely quiet.

　　 Those who have been busy for a year can finally take advantage of this rare opportunity to take a good rest.

　　 But compared to the whole day's sleep in previous years, the people of the Qingque tribe this year are a bit busy.

　　 Because they eat salt every day and have enough food, the people of the Qingque tribe will never do what they used to do. Once in the winter, they don’t have enough to eat and the salt goes away, making their bodies boring and sleeping.

　　 Now they, after the first seven or eight days, their sleep time has gradually decreased.

　　While they were not sleeping, Han Cheng, who was the son of God, found them new ways to work.

　　 In addition to making gloves, socks, and hats, there is also a tool for making soil.

It is inconvenient to simply grind the wooden sticks for digging. One is that they are not sharp enough, the other is that they are worn too much, and because the parts used for digging are too thin, they are easy to break, and the third is that the sticks are not wide enough. The soil excavated in one time is limited.

　　 Qingque tribe now needs soil to burn pottery, soil to build walls, and soil to grow rapeseed, so it is necessary to improve soil turning tools.

　　Han Cheng didn't have any other good solutions. Under such conditions, he could only learn from the wisdom of the ancients and make bones.

Years and months of hunting, there are a lot of bones in the tribe. From these bones, Han Cheng found out those that are hard and big, choose a suitable place, thin the edges on the stone, and sharpen it as much as possible. , And then combine them with the wooden sticks used to dig soil, and tie them together. In this way, a bone shovel is created.

　　 It’s easy to say things with the mouth. When you touch the upper lip and the lower lip, it will come out, but when it is really done, it is difficult.

　　 Because there are many things that need to be overcome.

　　 Not to mention the rest, just combining bones with wooden sticks is enough to cause headaches.

　　 There are no nails at this time, nor is it like the iron shovel made by later generations. Just put the wooden handle into the hole left on the shovel.

　　 It is not an easy task to use a wooden stick to connect the bones as a shank and bind them firmly.

　　After thinking about it, Han Cheng could only resort to a dumb method, which was to drill holes in the bones used as bony heads.

　　 The bone that makes the bone shovel is roughly rectangular, and the sharpened side is the width of the rectangle. The wooden handle needs to be fixed from the side facing it. (The language ability is not good. It is very simple. I just can't think of how to describe it. You can imagine the iron shovel, just like it. It's just a troublesome fixed method.)

　　 holes need to be drilled four, corresponding to each other.

　　The first pair of drills are located on the upper middle of the bone shovel head, and the second pair of drills are located on the upper part of the bone shovel, about two centimeters from the edge.

　　 Bundling the bones and then using rope grass is obviously impossible. Although the rope grass is tough, it is not wearable and easy to break.

　　Han Jiechi allows people to cut small pieces or damaged leather into many one-centimeter-wide strips and use them as ropes.

When binding, put the wooden handle in the middle of the two pairs of bone holes, and then pass the two ends of the leather rope through the front of the bone, cross the wooden handle, and then pass the leather rope through the holes on both sides of the wooden handle. Come back to the front, so that the wooden handle is entangled twice by the leather rope.

Pull tight and repeat the previous action. Repeat this five times. The wooden handle will be wrapped around the leather rope at least nine times. With these nine turns of leather rope, when the time is used for digging, the rope can basically be guaranteed. Will not break.

　　There is also a reason to drill the lower pair of bone holes in the upper middle position, so as to avoid the bottom end of the wooden handle on the back of the bone shovel from hitting the ground when digging, which enhances the usability of the bone shovel.

Of course, in order to fasten the bones and wooden handles, in addition to these small skills, there is another aspect that should not be ignored, that is, where the rope needs to be tied on the wooden handle, use a stone knife to carve a half-circle not too deep groove in advance come out. In this way, the leather rope can be jammed, reducing the possibility of loosening.

　　 And on the side where the bottom of the wooden handle fits with the bone, some changes must be made in advance.

　　 That is to use a stone knife and a cutting belt to smooth this side as much as possible, which can ensure that the wood and the bone have a large surface.

First, it can make the two stronger. Second, when digging the soil, because of the increased force area on the back of the bone, it can withstand greater force than a round wooden stick, that is It is not easy to happen because of excessive force, where the bone fragment and the wooden handle are attached to an exception.

　　 This is the experience that Han Cheng has combined with modern iron shovel, ‘Yangchang’ shovel and ancient people’s bones, after repeated experiments, and what he has created.

(Yangchang means that after the wheat is crushed with stone rollers in the wheat threshing field, the wheat stalks are removed, the remaining wheat is gathered together, and the wheat mixed with bran is shoveled and raised in the air. The wind will blow away the wheat bran and other things, leaving clean wheat and some unswept wheat ears on the ground.

　　Of course, this method is also applicable to soybeans and rapeseed.

　　I used this method to process wheat when I was young~www.wuxiahere.com~When I was older, there was a ‘raising machine’ with electricity or a machine, and later there was a combine harvester...)

　　 In the absence of metal tools, the manufacture of bone shovel is not easy. Not to mention the rest, just drilling the bones with sharp stones is very difficult and requires a lot of effort.

　　 This is the reason why Han Cheng didn't mention making bone shovel before, but waited until it snowed in winter and everyone was free to start making it.

　　 Although it is said that sharpening an axe does not accidentally chop wood, if it takes too long to sharpen an axe, it will definitely delay cutting wood within a certain period of time.

　　 Especially when Han Cheng has been thinking about building the wall before the heavy snow falls.

　　 Witch is still eager to learn and cherish knowledge as always. When the people in the Korean Trading Tribe did these things, he watched them from the side. After understanding, just as before, the cave's inner cave began to record.

　　 Now the space inside the inner cave has become much narrower, this is because the witch has recorded too many things.

　　 For these things, Wu Baobao is very, not allowed to put them outside the inner cave.

　　 This is the result of Han Cheng improving Wu's writing materials and replacing heavy stone slabs with fired pottery plates. Otherwise, there might not be much place to step down in the inner cave now.

Wu was reluctant to record the precious knowledge on the pottery board at first, but after using it twice, the pottery board was so easy to use that he immediately let him put aside the slab that he had inherited from the previous witch. The habit of recording knowledge.

(Hohohoho! The classification is forced! Comrades drop a few more recommendation tickets at me. The last book stops at the classification. This one will let me go further.-Very happy and looking forward to it The Mo Shou Bai.)
