I'm doing infrastructure in ancient times

If you want to make a powerful bow and arrow, you must find at least five things: stems, horns, tendons, glue, silk, and it is best to add lacquer.

The so-called stem refers to wood. The frame of a bow is made of wood, but not all stems can be used to build a bow. It must meet the conditions of hardness and elasticity, so that it will not be hard because of excessive force. To be broken, it must be elastic to be plastic. These two characteristics are very important and cannot be dispensed with.

Cheng Yang kept breaking the branches along the way, just to feel their texture. Although they are just some dead branches that fell on the ground, they can give people a different feeling.

It is not difficult to find suitable wood, and Cheng Yang soon found a more ideal target.

He thought it would be a good choice to use Zhe wood to make bows.

Zhe wood is hard and elastic, and it is a rare and good material. Most importantly, Cheng Yang found many such trees in the dense forest.

After finishing the main material, Cheng Yang felt at ease, and began to pick up the dead branches on the ground honestly and violently. After a while, their baskets were full.

"Cheng Yang, what are you doing with the horns?"

Meng asked curiously.

As soon as they returned to the tribe, they quickly put down the basket on their backs and poured out all the dead branches inside.

Seeing that the basket was cleared and emptied, Meng was satisfied, ready to carry his own small basket on his back, and then go to pick up some firewood.

But as soon as he picked up the basket, he was dragged away by Cheng Yang. Along the way, he was thinking about what Cheng Yang was going to take him this time, and he was very much looking forward to it.

As Cheng Yang's loyal fan, he firmly supports any of Cheng Yang's actions, and believes that they must be very meaningful things. Facts have also proved that Meng's idea is not wrong. It has brought miracles and made everyone's life more and more comfortable.

But watching Cheng Yang pick up these goat horns, he was suddenly stunned. He couldn't figure out what these goat horns could be used for.

Is it for eating?Meng's expression was a bit tangled, these goat horns didn't look like something delicious, Meng's heart was very tangled, and finally he decided to trust Chengyang.

He cheered himself up in his heart, and decided that even if Cheng Yang asked him to eat the goat horns raw, he would not refuse!

Mentally prepared, Meng generously looked at Cheng Yang, as if he was ready to sacrifice himself.

However, after waiting for a long time, Cheng Yang did not hand him the goat's horn, but fiddled with it by himself.

Seeing Meng staring at him, Cheng Yang picked out one of the horns in his arms and handed it over.

"Hey, you come and do it together..."

There are many types of bows and arrows, among which Cheng Yang is more familiar with the ox horn bow, its range and lethality are quite powerful.

If you want to make an ox horn bow, you must have ox horns. As far as Cheng Yang knows, no one in the tribe has ever seen a ox before, so he won't be able to find ox horns anytime soon.

Cheng Yang felt a little regretful, but it didn't matter. Although they didn't have horns, they didn't lack horns.

Goat horns are probably worse than cow horns, but they still work.

What he has to do now is to thin the horns as much as possible and grind them to a uniform thickness, so that when pasting the handle, it can be tightly seamed with the bow. The horns will be attached to the inside of the bow arm, Therefore, it is necessary to thin the horns as much as possible, thereby reducing the weight of the bow, so as to increase the rebound speed of the horns.

There are so many goats in the Shuofeng tribe, so naturally there is no shortage of horns. Cheng Yang collected a batch, and now he was about to make a bow, so he took out all the horns he had put away.

He took a quick look at the horns in his hand that hadn't changed much after grinding them for a long time, and looked at the small pile piled up beside Cheng Yang. He didn't know whether he should be thankful that this thing was not for eating, or sad that he had to grind it so much. horns.

"Cheng Yang, why don't you let the clansmen grind the horns together?"

There are a lot of people in the tribe, everyone should work hard together, and they should be able to grind the horns quickly, right?

Cheng Yang also knew this truth, but now the clansmen in the tribe were preparing firewood for the winter, he knew that this was no joke, if there was not enough firewood, some clansmen would freeze to death in winter.

The tent they usually live in does not block the wind at all. Now that winter has not yet entered, Cheng Yang can already feel the cold in the night. Not to mention the clansmen, even he himself is not confident that he can guarantee himself in the freezing winter. Don't suffer.

If he caught a cold and didn't even have to see a doctor, he probably would have given up his life.

So in Cheng Yang's view, although making a bow is very important, there is also an urgent need to prepare a charcoal fire for the winter.

He planned to make a test product by himself first, just like the last time he fired the kiln, and only when the success rate was guaranteed, he would mobilize the manpower of the tribe on a large scale, otherwise the production of the tribe would be delayed.

What he does can only add bricks and tiles to the tribe, and basic work is the foundation of the tribe, and the big can't be lost because of small things.

Looking at the drooping little face, and looking at the pile of horns full of resentment, Cheng Yang knew that he thought grinding the horns was too boring.

He thought that the work would not be tiring, so he dragged Meng over to help, but he didn't expect that children are very active, and such a tedious task requires patience.

Cheng Yang thought for a while, looked at Cheng Yang, stretched out his palm, and said, "Why don't you give it to me, I'll grind it myself..."

He just wanted to be a test subject now, just grinding two goat horns, and it didn't take too much time. Before, he was just too excited to hold so many goat horns out.

Hearing that as long as you grind two goat horns, Meng won't feel tired immediately, so he refused, "No, I'll help you grind this horn."

This time, Cheng Yang called him to help alone, and when this was done, he would go back to brag about it in front of his friends.

When Cheng Yang made pottery before, he also called them to help. At that time, people from the tribe always came to ask them for information. Although Meng was a child, he also felt that Beier had face.

Thinking that only he would know how Cheng Yang made new things, he suddenly started to laugh in his heart, and suddenly felt not tired at all, wishing that Cheng Yang could make it right away.

Cheng Yang saw that his expression did not seem to be fake, so he did not refuse.

The two of them handled it together, and quickly finished grinding the two horns. They looked at Cheng Yang with bright eyes, waiting to see his next move.

On the contrary, Cheng Yang started to have a difficult time. He didn't know whether his next step should be to prepare the bow tendons first, or the bow glue first.

No matter which one is done first, it is a relatively big move, and it is impossible to hide those tribe members in the tribe.

Alas, Cheng Yang sighed, he just wanted to do research in a low-key way first, why is it so difficult?

Seeing Cheng Yang pack up his things and get up, he stared fiercely. Seeing that Cheng Yang was about to leave, he quickly chased after him.

"Chengyang, why are you going?"

Didn't you agree to create new things, why did you leave?
