Chapter 70 Shovels and Plates

Heavy snow covered the field, as if everything was 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 take a good rest.

However, compared to sleeping all day long in previous years, the people of the Qingque Tribe seem a bit busy this year.

Because they now eat salt every day and have sufficient food, the people of the Qingque tribe will no longer be like before. In the winter, they can't even eat enough and the salt will pass away, making them tired and sleeping 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 a new job for them.

In addition to making gloves, socks, and hats, there is another item that is used to make digging tools.

It is inconvenient to use a flat wooden stick for digging. First, it is not sharp enough; The excavated soil is limited.

The Qingque tribe now needs soil for burning pottery, soil for building walls, and soil for growing rapeseed. Therefore, it is very necessary to improve the soil-digging tools.

Han Cheng didn't have any good ways to tell. Under such conditions, he could only learn from the wisdom of the ancients and make bone shovels.

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 ground the edges on the stone to make them as sharp as possible. , and then combine them with the wooden sticks used to dig the soil, and tie them together, so that a bone shovel is formed.

It's easy to say things with the mouth, and it will come out when you touch the upper and lower lips, but it's difficult when you actually do it.

Because there are many things that need to be overcome.

Not to mention the rest, just combining the bone with the stick is enough to cause headaches.

At this time, there were no nails, and it was not like the shovels made by later generations. Just put the wooden handle into the hole left on the shovel.

It is really not an easy task to use the heel of the bone as a shovel handle to connect it with a wooden stick and bind it firmly.

After thinking about it, Han Cheng could only adopt a stupid method, which was to drill holes in the bones used as shovel heads.

The bone used to make the shovel is roughly rectangular, and the side that is sharpened is the width of the rectangle, and the wooden handle needs to be fixed from the side opposite to it. (Language skills are not good, it’s a very simple thing, but I just can’t remember how to describe it. You can imagine a shovel, just like it, but the fixed method is troublesome.)

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

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

Binding the bone shovel with rope grass is obviously useless. Although the rope grass is tough, it is not wear-resistant and is easy to break.

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

When binding, put 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 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 wrapped twice by the leather rope at once.

Tighten it tightly, and then repeat the previous action. After repeating this five times, the wooden handle will be wrapped by the leather rope at least nine times. With these nine turns of leather rope, when it is time to dig the soil, the rope can basically be guaranteed Will not break.

There is also a reason for drilling the lower pair of bone holes in the upper middle, so as to avoid the bottom of the wooden handle on the back of the bone shovel from pushing against the ground when digging the soil, which enhances the usability of the bone shovel.

Of course, if you want to tie the bone and the wooden handle firmly, in addition to these small skills, there is another aspect that cannot be ignored, that is, use a stone knife to carve a half-circle groove that is not too deep at the place where the rope needs to be tied on the wooden handle. come out.This catches the leather cord and reduces the chance of it coming loose.

And on the side of the bottom of the wooden handle that fits the bone, some changes have to be made in advance.

That is to use a stone knife to chop and grind this side as smooth as possible, which can ensure a large bonding surface between the wood and the bone.

On the one hand, it can make the two stronger, and on the other hand, when digging, because the force-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 to make an exception at the joint between the bone piece and the wooden handle due to excessive force.

This is the experience that Han Cheng summed up and what he created after many consecutive experiments, combining the modern iron shovel, the wooden shovel used for 'lifting the field', and the ancient bones.

(Yangchang means that after the wheat is crushed with stone rollers in the threshing floor, the wheat stalks are removed, the remaining wheat is gathered together, and the mixed wheat bran is lifted up in the air with a wooden shovel. The wind will blow away the chaff and other things, and the clean wheat and some ears of wheat that have not been driven away will remain on the ground.

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

When I was young, I still used this method to process wheat. When I was older, there was an electric or machine-driven 'field lifter', and then there was a combine harvester...)

Now that there is a lack of metal tools, the manufacture of bone shovels is not easy. Not to mention other things, just drilling holes with sharp stones on the bones is very difficult and requires great effort.

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

Although sharpening the ax does not miss the skill of chopping firewood, but if it takes too long to sharpen the axe, within a certain period of time, the chopping of firewood will definitely be delayed.

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

Wu was still eager to learn and cherish knowledge as always. He watched from the sidelines when the people in the Hanjiao tribe were doing these things. After understanding, he began to record in the inner hole of the cave just like before.

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

For these things, baby witches are very good, and it is not allowed to put them in places other than the inner cave.

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

For the precious knowledge recorded on the terracotta board, Wu was a little reluctant at first, but after using it twice, the ease of use of the terracotta board immediately made him abandon the slate board inherited from the previous Wu. Habit of recording knowledge.

(Ho ho ho ho! The category is pushed! Comrades, give me a few more recommendation tickets. The last book stopped at the category. This book will let me go further. ——Extremely happy and looking forward to it Mo Shoubai.)

Chapter 71 The Fearful Primitive

The courtyard wall still needs to be heightened.

Han Cheng originally expected the wall to be [-] meters high, but later, due to the rush of the construction period, he lowered the courtyard wall from [-] meters to [-] meters.

The two-meter-high wall can block most of the beasts, but it is a bit difficult to block people. Now that it is snowing again, the wall looks a little lower.

Han Cheng originally had the idea of ​​raising the fence after the Spring Festival began.

The original plan was to increase the height to the originally expected [-] meters. Now because of the addition of a possible hostile tribe, he feels that the [-] meters wall is still too low. When the time comes, the wall may be raised to [-] meters or even more. higher.

After the wall is increased, the construction of the house needs to be put on the agenda.

Nowadays, with the increase of utensils in the tribe, the space in the cave is becoming more and more crowded.

And because many people live together, the air is inevitably not fresh.

Of course, another important reason is that at night, the original singing voice is too loud, and sometimes it keeps coming and going, which makes Han Cheng often not sleep well.

In the past, it was better when everyone was busy. The heavy labor left the brothers and the others with little energy to do what they love to do.

In the past, because of food and salt problems in the winter, everyone was helpless about this matter, and only in the spring did they become restless on a large scale.

But it’s different now. Sufficient food and salt, as well as a leisurely life, let them have too much energy to vent, and they can come anytime, anywhere, so that now at night, many original ditties intertwined, humming Non-stop, particularly affecting sleep.

Especially Hei Wa and Zhuang, firstly they are young and powerful, secondly, they are newlyweds, and thirdly, Zhuang has a thick throat, and his loud singing can wake people up from their sleep.

If it weren't for Han Cheng's fear of delaying the tribe's population development plan and worrying that Hei Wa would never be happy again, Han Cheng would have gone over and kicked them both!

It is precisely because of this that Han Cheng is eager to put the construction of the house on the agenda.
