Heavy snow covered the wilderness, seeming to have sealed everything, and the whole world seemed extremely quiet.
People who have been busy for a year can finally take advantage of this rare opportunity to take a good rest.
However, compared to previous years when they slept all day long, the people of the Qingque tribe seemed a little busy this year.
Because they now eat salt every day and have enough food, the people of the Qingque tribe will no longer be like before. In winter, when they don't have enough to eat and the salt goes away, they feel tired and fall asleep all the time.
Now, after the first seven or eight days, their sleep time has gradually become less and less.
While they were not sleeping, Han Cheng, the son of God, found new jobs for them.
In addition to making gloves, socks, and hats, another item is making tools for digging.
It is inconvenient to simply use a flattened wooden stick for digging. Firstly, it is not sharp enough. Secondly, it is worn too much. Moreover, it is easy to break because the part used for digging is too thin. Thirdly, the wooden stick is not wide enough.
The amount of soil that can be excavated is limited.
The Qingque Tribe now needs soil to make pottery, build walls, and turn the soil to grow rapeseed. Therefore, it is very necessary to improve soil-turning tools.
Han Cheng didn't have any other ideas. Under such conditions, he could only draw on the wisdom of the ancients and make a bone shovel.
After years of hunting, the tribe collected a lot of bones. Han Cheng found out the hard and big ones from these bones, chose a suitable place, and thinned the edges on the stones to make them as sharp as possible.
, and then combined with the wooden sticks used to dig soil, and tied them together, thus, a bone shovel was created.
It's easy to say something with your mouth. It comes out as soon as the upper lip and lower lip touch. But when you actually do it, it is difficult.
Because there are many things that need to be overcome.
Not to mention the rest, just combining the bones with the sticks is enough to give people a headache.
There were no nails at this time, and they were not like the shovels made in later generations. Just push the wooden handle into the hole left on the shovel.
It is not an easy task to use the bones as a shovel handle to connect them together with wooden sticks and bind them firmly.
After thinking about it, Han Cheng could only adopt a stupid method, which was to drill holes in the bone that was used as a bone shovel head.
The bone used to make a bone shovel is roughly rectangular. The sharpened side is the width of the rectangle, and the wooden handle needs to be fixed from the side facing it. (I can’t express myself well, it’s a very simple matter.
I just can’t think of how to describe it. You can imagine a shovel, it’s just like it, but the fixing method is troublesome.)
Four holes need to be drilled, corresponding to each other.
The first pair of drills are drilled in the middle of the bone shovel head, and the second pair of drills are drilled in the upper part of the bone shovel, about two centimeters from the edge.
It is obviously impossible to use rope to tie up the bone shovel. Although the rope is tough, it is not wear-resistant and can be easily damaged.
Han Chenggong asked people to cut many one centimeter wide strips from small pieces or damaged leather and use them as ropes.
When binding, first place the wooden handle in the middle of the two pairs of bone holes, then pass the two ends of the leather rope through the front of the bone, cross the wooden handle, and then thread the leather rope through the holes on both sides of the wooden handle.
Go back to the front, and the wooden handle will be wrapped twice by the leather rope at once.
Tighten it hard, and then repeat the previous action. Repeat this five times. The wooden handle will be wrapped with the leather rope at least nine times. With these nine turns of the leather rope, when the time comes to dig the soil, the rope can basically be guaranteed.
Will not break.
There is a reason why the lower pair of bone holes are drilled in the upper middle position. This can prevent the bottom end of the wooden handle on the back of the bone shovel from hitting the ground when digging soil, thereby enhancing the usability of the bone shovel.
Of course, if you want to tie the bones and the wooden handle firmly, in addition to these tips, there is another aspect that cannot be ignored, that is, where the rope needs to be tied on the wooden handle, use a stone knife to carve a half-circle of grooves that are not too deep.
Come out. This way you can catch the leather cord and reduce the possibility of loosening.
Moreover, some changes must be made in advance on the side of the bottom of the wooden handle that fits the bone.
That is to use a stone knife to chop and grind this side as smooth as possible. This can ensure that the wood and the bone have a large joint surface.
Firstly, it can make the two stronger, and secondly, when digging soil, because the stress-bearing area on the back of the bone increases, it can withstand greater force than a round wooden stick, that is,
It is not easy for the joint between the bone piece and the wooden handle to break due to excessive force.
This is the experience that Han Cheng summed up and what he created after conducting many experiments in succession, combining modern iron shovels, wooden shovels used for 'raising the field', and the bones of the ancients.
(Winding means that after the wheat is crushed with stone rollers in the threshing field, the wheat straw is removed, the remaining wheat is gathered together, and the wheat mixed with wheat bran is scooped up with a wooden shovel and raised in the air.
The wind will blow away the wheat chaff and other things, leaving clean wheat and some ears that have not been driven away on the ground.
Of course, this method is also applicable to soybeans, rapeseed, etc.
When I was young, I still used this method to process wheat. When I was older, there were "winding machines" that used electricity or machines, and later there were combine harvesters...)
In the absence of metal tools, it is not easy to make bone shovels. Not to mention other things, just drilling holes in bones with sharp stones is very difficult and requires a lot of effort.
This is also the reason why Han Cheng didn't mention making bone shovels before, but waited until it snowed in winter and everyone was free to start making them.
Although it is said that sharpening an ax will not hinder the ability to chop wood, but if it takes too long to sharpen the ax, it will definitely delay chopping wood within a certain period of time.
Especially when Han Cheng has been thinking about building the wall before the heavy snow falls.
Wu was still as studious and cherished knowledge as ever. When the people in Han Chengjiao tribe were doing this, he watched on the sidelines. After understanding it, he started recording in the inner cave of the cave just like before.
Nowadays, the space inside the inner cave has become much smaller. This is because the wizard has recorded too many things.
Witches are very precious about these things and are not allowed to put them outside the inner cave.
This is the result of Han Cheng improving the writing materials for Wu and replacing the heavy stone slabs with fired pottery slabs. Otherwise, there might not be much place to set foot in the inner cave now.
Wu was a little reluctant to record this precious knowledge on the pottery board at first, but after using it twice, the ease of use of the pottery board immediately made him put aside the knowledge on the stone board that he had inherited from the previous witch.
The habit of recording knowledge.
(Ho ho ho! I am strongly recommended in the category! Comrades, please give me more recommendation votes. The last book stopped at the classification, this one will make me go further. - Extremely happy and looking forward to it
