The snow covered the fields, as if everything had been sealed, and the whole world seemed extremely quiet.

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

However, compared to sleeping all day in previous years, the people of the Qingque tribe are a little busy this year.

Because they now eat salt every day and have enough food, the people of the Qingque tribe will never be like before, and they will not even be able to eat enough salt in winter, so that their bodies will be bored and they will always sleep.

Now, after the first seven or eight days, they have gradually slept less.

When they weren't sleeping, Han Cheng, as the son of God, found them a new job.

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

It is not convenient to simply flatten the wooden stick for digging the soil, one is not sharp enough, the other is that it is too worn, and because the part used to dig the soil is too thin and easy to break, the third is that the wooden stick is not wide enough, and the soil excavated each time is limited.

The Qingque tribe now needs to use soil to burn pottery, build a fence with soil, and grow rape also needs to turn over the soil, so it has become a very necessary thing to improve the soil turning tools.

Han Cheng didn't have any other good way, and under such conditions, he could only learn from the wisdom of the ancients and make bone shovels.

After years of hunting, there are many bones in the tribe, Han Chengcheng finds those bones that are both hard and big, chooses the right place, grinds the edges on the stone, sharpens them as much as possible, and then combines them with the wooden sticks used to dig the soil before, and bundles them together, so that a bone shovel is also created.

Things are very simple to say with your mouth, and when you touch the upper and lower skins of your mouth, it comes out, but when you actually do it, it is difficult.

Because there are many things that need to be overcome.

If nothing else, just combining the bones with the sticks is enough to give a headache.

At this time, there were no nails, and it was not like the shovel made by later generations, and the wooden handle was simply threaded through the hole left on the shovel.

It is not easy to attach the bone to the bone as a shovel handle with a wooden stick and tie it strongly.

After thinking about it, Han Cheng could only use a stupid method, that is, to drill holes in the bones used as bone shovel heads.

The bone used to make the shovel is roughly rectangular, and the sharpened side is rectangular wide, and the wooden handle needs to be fixed from the side facing it. (The language ability is not good, the very simple thing is that I can't remember how to describe it, you can imagine the shovel, just like it, but the fixed method is troublesome.) ）

Four holes need to be drilled, two by two.

The first pair is drilled in the middle of the shovel head, and the second pair is drilled in the upper part of the shovel, about two centimeters from the edge.

It is obviously not possible to tie the bone shovel and then use the rope grass, although the rope grass is tough, but it is not wear-resistant, and it is easy to break.

Han Chengcheng had people cut out small pieces of leather or damaged leather into many one-centimeter-wide strips and use them as ropes.

When binding, first put the wooden handle in the middle of the two pairs of bone holes, and then pass the two ends of the leather rope from the front of the bone respectively, cross around the wooden handle, and then wear the leather rope back to the front from the holes on both sides of the wooden handle, so that the wooden handle is wrapped around the leather rope twice at once.

Pull hard, and then repeat the previous action, so repeat five times, the wooden handle will be wrapped around the leather rope at least nine times, with these nine circles of leather rope, when the time is used to dig the soil, the rope can basically ensure that the rope 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 pushing up to the ground when digging, enhancing the usability of the bone shovel.

Of course, in addition to these tips, there is another aspect that should not be overlooked, that is, where the rope needs to be tied to the wooden handle, use a stone knife to carve out half a groove that is not too deep in advance. This will allow the rope to be caught and reduce the possibility of loosening.

In addition, the side of the bottom of the wooden handle that fits the bone has to be changed in advance.

That is, use a stone knife to chop and grind this side as much as possible, which can ensure that the wood and bone have a large fit.

First, it can make the two firmer, and secondly, when digging the soil, because the force area on the back of the bone increases, it can withstand greater force than the round wooden stick, that is, it is not easy to make an exception due to excessive force.

This is the experience and things created by Han Cheng after many experiments in a row, after combining the modern shovel and the wooden shovel used for 'Yangchang' and the bones of the ancients.

(Yangchang means that after the wheat is crushed with stones in the threshing field, the wheat stalks are taken away, the remaining wheat is gathered together, and the wheat mixed with the wheat bran is lifted in the air with a wooden shovel, and the wind will blow away the wheat bran and other things, and the clean wheat and some ears of wheat that have not been opened are left on the ground.)

Of course, this method also applies to soybeans and oilseed rape.

When I was younger, I still used this method to process wheat, and when I was older, I had a 'lifting machine' with electricity or a machine, and then there was a combine harvester...... ）

In the absence of metal tools, it is not easy to make a bone shovel, and the rest of the work is very difficult and requires great effort just to drill holes in the bones with sharp stones.

This is also the reason why Han Cheng didn't mention making bone shovels before, and waited until after the snow in winter, when everyone was idle before starting to make it.

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

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

Wu is still as studious and cherished knowledge as ever, and when the people in the Han tribe did this, he watched from the sidelines, and after understanding it, as before, the inner cave of the cave began to record.

The space inside the cave has become much smaller now, and this is because the witch has recorded too many things.

For these things, the witch baby is very good, and it is not allowed to put it outside the inner hole.

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 may not be much place to put his feet in the inner cave now.

Wu was a little reluctant at first to record this valuable knowledge on the pottery tablet, but after using it twice, the ease of use of the pottery plate immediately made him abandon the habit of recording knowledge on the stone tablet inherited from the previous Wu.

(Roar, roar!) The category is strongly pushed! Comrades, let's throw a few more recommendation votes at me, the last book will stop at classification, this one will let me go further. - Extremely happy and expectant. ）
