The heavy snow covered the fields, as if sealing off everything. The whole world seemed extremely quiet.

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

However, compared to previous years when people slept all day, the people of the Qingque tribe seem to be 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, when winter came and they would not have enough food, lose salt, feel weak and sleep all the time.

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

When they were not sleeping, Han Cheng, the Son of God, found new jobs for them.

In addition to making gloves, socks and hats, another activity is making tools for digging.

A simply flattened wooden stick is not convenient to use for digging. First, it is not sharp enough. Second, it is too worn. In addition, the part used for digging is too thin and easily breaks. Third, the stick is not wide enough, so the amount of soil dug each time is limited.

The Qingque tribe now needs soil to make pottery, build walls, and grow rapeseed, so improving the soil-turning tools has become a very necessary thing.

Han Cheng didn't have any better 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 picked out the hard and large ones from these bones, chose a suitable place, and grinded the edges on the stone to make them as sharp as possible. Then he combined them with the wooden sticks used to dig the soil and tied them together. In this way, a bone shovel was made.

It's easy to say things with your mouth, just a touch of the upper and lower lips and they come out, but when you actually do it, it becomes difficult.

Because there are many things that need to be overcome.

Not to mention anything else, just the task of combining the bones and the sticks is enough to give you a headache.

There were no nails at that time, and it was not like the shovels made in later generations, where you just had to insert the wooden handle into the hole on the shovel.

It is not an easy task to use the bones as shovel handles, connect them together with a wooden stick and tie them tightly.

After much thought, Han Cheng could only resort to the stupid method, which was to drill a hole in the bone used as a shovel head.

The bone used to make the bone shovel is roughly rectangular, and the side that is sharpened is the width of the rectangle, so the wooden handle needs to be fixed from the side opposite it. (I am not good at expressing myself in words. It is a very simple thing, but I just can't remember how to describe it. You can imagine that the iron shovel is the same as it, but the fixing method is more complicated.)

Four holes need to be drilled, two by two corresponding to each other.

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

It is obviously not possible to use rope grass to tie the bone shovel. Although rope grass is tough, it is not wear-resistant and can be easily damaged.

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

When tying, 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 them around the wooden handle, and then pass the leather rope back to the front through the holes on both sides of the wooden handle. In this way, the wooden handle is wrapped with two leather ropes at once.

Pull it tight and 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 leather rope, it can be basically guaranteed that the rope will not break when it is used to dig the soil.

There is a reason why the pair of bone holes below are drilled in the upper middle position. This can prevent the bottom of the wooden handle on the back of the bone shovel from hitting the ground when digging, thereby enhancing the usability of the bone shovel.

Of course, in addition to these tips, there is another aspect that cannot be ignored in order to tie the bone and the wooden handle tightly. That is, use a stone knife to carve a half-circle groove that is not too deep on the wooden handle where the rope needs to be tied. This will hold the leather rope and reduce the possibility of loosening.

Also, some changes need to 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 to make it as smooth as possible, which can ensure that there is a large fit between the wood and the bone.

Firstly, it can make the two more secure, and secondly, when digging, due to the increase in the force-bearing area on the back of the bone, it can withstand greater force compared to a round wooden stick. In other words, it is less likely that the bone and the wooden handle will break due to excessive force.

This is the experience and creation that Han Cheng summarized after many experiments, combining modern iron shovels, wooden shovels used for "winnowing" and ancient people's bone plows.

(Winnowing means that after the wheat is crushed with a stone roller in the threshing floor, the wheat stalks are removed and the remaining wheat is gathered together. The wheat mixed with bran is scooped up with a wooden shovel and thrown into the air. The wind will blow away the bran and other things, and the clean wheat and some wheat ears that have not been blown away will remain on the ground.

Of course, this method also applies to soybeans, rapeseed, etc.

When I was young, I still used this method to process wheat. When I was older, I had electric or mechanical winnowing machines, and later I had combine harvesters...)

In the absence of metal tools, it is not easy to make a bone shovel. Not to mention other things, just drilling holes in the bones with sharp stones is extremely difficult and requires tremendous effort.

This is also the reason why Han Cheng did not mention the matter of making bone shovels before, and waited until the snow fell in winter when everyone had free time to start making them.

Although sharpening an axe does not delay chopping wood, if it takes too long to sharpen the axe, it will definitely delay chopping wood for a certain period of time.

Especially since Han Cheng had been thinking about building the wall before the heavy snow fell.

Wu was still as studious and cherished knowledge as ever. When the people in Han Chengjiao's tribe were doing these things, he watched from the side. After he understood them, he began to record them in the inner cave as he did in the past.

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

The witch treasures these things very much and does not allow them to be placed anywhere other than the inner cave.

This is the result of Han Cheng improving the writing materials for Wu, replacing the thick stone slabs with fired pottery plates. Otherwise, there would probably not be much space to step on in the inner cave.

The witch was somewhat reluctant at first to record such valuable knowledge on the pottery tablet, but after using it twice, he was so useful that he immediately abandoned the habit of recording knowledge on stone tablets that was passed down from the previous witch.
