The snow covered the field, as if everything was sealed, 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 the sleeping day in previous years, the people of the Qingque Tribe seem a little busy this year.

Because people in Qingque tribe eat salt every day and have sufficient food, they will no longer be like before. When winter comes, they will not even be full and have salt flowing away, making them lose energy and they will always sleep.

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

When they were not 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 making digging.

It is not convenient to simply grind a flat wooden stick for digging. First, it is not sharp enough, second, it is worn too hard, and because the part used to dig the soil is too thin and easy to break. Third, the stick is not wide enough, and the soil excavated is limited each time.

The Qingque Tribe now requires soil to burn pottery, soil to build walls, and soil to grow rapeseed also requires soil to be turned over, so improving the soil turning tools has become a very necessary thing.

Han Cheng had no good idea. Under such conditions, he could only learn from the wisdom of the ancients and make bone shavings.

After years of hunting, there are many bones collected in the tribe. Han Cheng found those hard and big ones from these bones, chose the right place, ground the edges thinly on the stone, and try to sharpen them as much as possible. Then, combined with the wooden sticks used to dig the soil, tie them together, so that a squid was created.

Things are simple to say with your mouth. When you touch the upper and lower mouths, it will come out, but when you actually do it, it will be difficult.

Because there are many things that need to be overcome.

Not to mention the rest, just combining bones and wooden sticks is enough to make people feel headache.

At this time, there were no nails, and it was not like the iron shovels created by later generations. Just pass the wooden handle into the holes left on the iron shovels.

It is really not easy to connect the bones and tie them together with a wooden stick as a shank.

After thinking about it, Han Cheng could only use a stupid method, which was to drill holes on the bones used as bone shavings.

The bones that make bone shavings are roughly rectangular. The side that is sharply ground is the width of the rectangle, and the wooden handle needs to be fixed from the side facing it. (There is a very simple thing, but I can't remember how to describe it. You can imagine that iron shavings are just like it, but it's a troublesome way to fix them.)

Four holes need to be drilled, and the two correspond to each other.

The first pair of drills is located upside the middle of the squid head, and the second pair of drills is located on the upper part of the squid, about two centimeters away from the edge.

It is obviously impossible to tie the bone shroud and then use ropes and straws. Although ropes and straws are tough, they are not wear-resistant and can easily be damaged.

Han Cheng made people cut out many long strips one centimeter wide for small pieces or broken leather, and used them as ropes.

When binding, first place the wooden handle between 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 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 by the leather rope at once.

Tighten tightly, and repeat the previous action. Repeat this five times, the wooden handle will be wrapped around at least nine circles by the leather rope. With these nine circles of leather rope, when time is used to dig the soil, the rope will basically be guaranteed not to break.

There is also a reason to drill the pair of bone holes below in the upper middle position, which can prevent the bottom of the wooden handle on the back of the bone shroud from reaching the ground when digging, enhancing the availability of the bone shroud.

Of course, in addition to these tips, there is another aspect that cannot be ignored when binding the bones and the wooden handle. That is, when the rope needs to be tied on the wooden handle, use a stone knife to carve half a circle of not too deep grooves. This way, the leather rope can be stuck and the possibility of looseness can be reduced.

Moreover, 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 to cut and sharpen this side as smooth as possible, which can ensure that the wood has a large fitting surface with the bones.

First, it can make the two more firmer. Second, when digging soil, because the area under the back of the bone increases, it can withstand greater force than a round wooden stick, which means it is not easy to make an exception when the bone piece and the wooden handle are fitted with too much force.

This is the experience and what he created after many experiments, Han Cheng combined modern iron shovels, wooden shovels used in "yangchang" and bone hoes from ancient people.

(The yangchang means that the wheat is crushed with stones in the threshing farm, and then removes the wheat straw, gathers the remaining wheat together, and shovels the mixed wheat bran with wooden shovels and raises it in the air. The wind will blow away the wheat bran and other things, leaving the clean wheat and some unblocked wheat ears on the ground.

Of course, this method is also suitable for soybeans and rapeseed.

When I was young, I used this method to process wheat. When I was older, I had electricity or a ‘sung machine’ with machines, and then there was a combine harvester…)

Nowadays, the lack of metal tools is not easy to manufacture. Not to mention the rest, just drilling holes with sharp stones on the bones is very difficult and requires a lot of effort.

This is why Han Cheng didn't mention making bone shovels before, and waited until it snowed in winter, and everyone was idle before starting to make them.

Although grinding an axe does not delay cutting wood, if it takes too long to grind an axe, it will definitely delay cutting wood within a certain period of time.

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

Wu was still as eager to learn and cherish knowledge as ever. When the people in the Han Chengjie tribe did these things, he watched them from the side. After understanding them, he began to record the inner hole of the cave as before.

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

For these things, Wu Bao is very good and is not allowed to be placed outside the inner hole.

This is the result of Han Cheng improving the writing materials for Wu and replacing the thick stone slabs with fired ceramic plates. Otherwise, there would probably be not much place to put in the inner hole now.

Wu was a little reluctant at first to record these valuable knowledge on the ceramic plate, but after using it twice, the usefulness of the ceramic plate immediately made him abandon the habit of recording knowledge on the stone slabs inherited from the previous witch.

(Ho huh huh! I have been forced to recommend it in the category! Comrades, please send me a few more recommendation votes. The previous book stopped at the category. This book will let me go further. - Mo Shoubai, who is extremely happy and looking forward to it.)
