Wang Yang wrapped the wet animal skin and took it to the bonfire with the template. He slowly opened the animal skin in front of the onlookers.

What caught my eye were the dark yellow bronze ware embedded in the template, which attracted everyone's surprise.

They all know that those stones that are just green, how come they come in and out, not only have their shapes changed, but their colors changed?

Suddenly, they surrounded Wang Yang curiously and asked in a verbal manner.

Wang Yang had also refined a piece of copper green before, but that piece was too small, not to mention the size. He refined a small layer of copper, and everyone didn't care at all, and thought the green stone was burned out.

They have seen every step of this time, so they are extremely shocked.

I haven't heard that they can change the shape and color. You should know that they burn white clay, and what they burn is white porcelain, and the coffee is clay, and the dark red bricks are similar.

Perhaps there was a slight change in color, but the shape was absolutely not changed.

Faced with such a strong curiosity that he was about to swallow himself, Wang Yang had to patiently explain to them that this was similar to the principle of tin. As he burned, he burned it into liquid, and then it became cold and fixed.

Everyone was still very confused. It was true that tin was like this, but the color of tin had not changed.

Wang Yang smiled and pointed to the dark charcoal, saying that before the charcoal was burned, wasn’t it also white wood?

Only then did everyone understand and no longer investigate this issue.

Wang Yang gently wiped his sweat. It was impossible to explain the chemical knowledge clearly, but he was still secretly proud. His nonsense skills reached another level.

Soon, everyone was attracted by the bronze ware of different shapes. They went forward to touch it, and found that it was not very hot. They poured it out and looked at it in the fire.

I saw those bronze ware flashing brightly, which looked very beautiful.

But I just thought it looked good and had no use, so I threw it aside and ignored it.

Wang Yang also took the initiative to check these bronze ware. He picked up a dagger, which was like a thin cake...dagger.

Ahem, let’s call it a dagger, because in Wang Yang’s vision, he really planned to make it a dagger.

But who knew that there was too much green stone copper juice on the dagger template, and the template overflowed. As a result, a good dagger turned into a big copper cake... I can't eat it yet!

He took other bronzes and found that they were more or less imperfect, either overflowing or not enough.

Wang Yang had some expectations about this, but he was not too surprised.

He could not calculate the exact copper content of these patinas for the time being, nor did he know the volume of a patina, nor did he know the capacity of the template.

All of these require precise and rigorous calculations.

Wang Yang knew the calculation formula. He had no measurement tools, and whether it was a length measurement tool or other measurement tools, they were completely missing.

If you want to convert perfectly, there are two ways to make the copper juice in each template.

The first is to open a small hole at the critical point of the template to let the excess copper juice flow out, just like the design of a bathroom. There is a small hole to drain water so that the water will not fill the bathroom.

This is very technically demanding, but it is very good.

Another is to create units of measurement, which will lay the normative nature of many tools in the future and is a far-sighted approach.

However, there are many aspects that need to be considered, and it is basically impossible to promote it when the hieroglyphics are incomplete.

No matter which one is actually a very stupid and troublesome way. Although it has its own clever principles, it is really not suitable for making it without anything.

Wang Yang also put these two methods behind his back and ignored them.

He has a better and simpler way, which can be done as simple as a child of three years old.

He said before that everything is difficult at the beginning because at the beginning, there were no other tools to use, but now that there are bronzes, tools can be made, making time very simple.

The tools he made had come out, a pair of two meters long pliers.

What can long pliers be used for? Generally speaking, they can be used to stir in the fire and can remove the sweet potatoes in the fire.

But using it here is naturally a different scene.

He planned to do it, and no matter how much he explained it, it would not be as practical as possible.

But before he started, he saw Xiaohong frowning and found him and told him that she wanted to go to the forest.

Wang Yangxin was not here, so he casually said, "If you want to go, don't play for too long, go back to the prairie as soon as possible."

Uh... Xiaohong was stunned for a moment, and then said angrily that she was not going to play there.

Wang Yang is happy, what else are you planning to do besides playing?

Xiaohong expressed her ideas in pictures.

In fact, one of the reasons I came back this time was that I planned to find Wang Yang, but Wang Yang came back and there was no need to find him.

Another reason is that because there are too many animals raised on the grassland, they attract a lot of wild animals. They often attack the animals, but fortunately they basically failed.

But those wild beasts didn't want to let go of such a large piece of sweet fat meat, and refused to leave, and were always wandering nearby and attacking from time to time.

The attacks were repeatedly shot back by the people with spear arrows, and they did not make them too arrogant.

Unfortunately, the killing of spear arrows is extremely limited. At present, a large number of spear arrows are not made of sharp stones, because the polishing and processing skills are too high and it is difficult to satisfy.

Therefore, most spear arrows are sharpened wooden tips, which are completely caused by the firing power of the spear thrower itself.

Many wild beasts rely on their thick and hard fur, and they will not be shot too deeply if they are shot. They are not in danger of life, so they will pluck their courage to make a lot of impact.

It is impossible for everyone to come forward and attack, otherwise the other beasts around would find a breakthrough to rush over.

Killing a few animals is a trivial matter, but I am afraid of disturbing the animals and running around, which is really fatal.

So I had no choice but to turn a blind eye to those beasts and let them rag on them.

It can be said that the one who can keep animals and people safe is the most dependent on spear arrows, but spear arrows are thin and long, and are particularly prone to breaking and consumption increases sharply.

She was worried that before the beasts retreated, she would be in chaos because of insufficient spears and arrows, so she came back this time and planned to take a large number of spears and arrows over.

Unfortunately, qualified spear arrows are not that easy to make. A spear that is too thick can not shoot far away, and a spear that is too thin cannot kill. A good spear arrow is even harder to create than a wooden spear.

Since the tribe entered the farming industry, the spear has entered a stage of stagnation in development.

This does not mean that the spear arrow cannot be produced, but that the current development speed of the tribe far exceeds the production speed of spear arrows.

When in the canyon, it is almost enough to produce five spear arrows a day, and the number of damage is about three. Because the population is small, there are fewer hunting activities.

Correspondingly, less damage is required.

Later, when the population grew, there were more hunting behaviors, so there were naturally more damage. However, when agriculture was just developed, everyone's main work was still on the production of spears and arrows.

If I have more damage, I will produce more!

In this way, nothing went wrong.

When the focus was completely on agriculture, everyone was reclaiming wheat fields and orchards, and later developed clay and other industries. Everyone rushed to do this and that, and the production of spears and arrows basically returned to the old path of enough.

Actually, this is nothing. It has been a year since I returned to this old path, so I have never had any problems.

So the spear arrows are used less and less, and in the end they are only used for defense. However, the nearby wild beasts have long become spirits. They know that the human group is very powerful and they hide when they meet. Except for a few young men, they also come up to seek death. Everyone almost forgot what the spear arrows are used for.

As a result, the spear and arrow became less and less important.

Not only that, weapons, including wooden spears, are becoming less and less important, because everyone's focus no longer requires killing and hunting.

Don't have to play a life-and-death game with beasts, who can't afford to produce weapons?

Until now, only enough weapons in the tribe can be used. What is this concept?

That is to say, everyone has a spear, a sharp stone knife, and then it is gone! It is really gone!

It’s not that everyone doesn’t produce, but that production is very, very troublesome! Zhang San, who was working hard to produce except for the time when burning carbon.

But now the population of the tribe has increased several times, and processing conditions have not improved. Even if he does not eat, drink or sleep, he cannot produce it.

It can be imagined that after a while, the population will break through again and it will be impossible for everyone to have a wooden spear, and this number will grow bigger and bigger with time.

After listening to Xiaohong's description, Wang Yang wiped his face. He had never thought about this.

If it can continue to develop peacefully, the spear will naturally fall into an optional situation.

Unfortunately, the recent crazy development of animal husbandry has exposed new problems.

This era is not a world where there is no world where you can’t see half an animal when you visit a barren mountain. It is a world where giant beasts are like clouds and wild beasts are everywhere!

Three steps one small beast, five steps one monster, that’s not something to blow!

"It seems like a mistake!" Wang Yang touched his chin, his eyes flashed slightly, and he followed Xiaohong to the warehouse, counted the spear arrows, and found that there were less than a hundred spear arrows left!

He asked Xiaohong how many spear arrows it took to shoot a wild beast.

Xiaohong drew a picture and each beast had to shoot at least four or five spear arrows.

"It's too wasteful, too wasteful!" Wang Yang told her that spears and arrows are in short supply recently. News has passed, so try to shoot one arrow for each wild beast.

The purpose is not to kill wild animals, but to scare them away with some color.

Xiaohong nodded, immediately found someone, loaded a spear and arrow, and then issued a new defense plan, and asked someone to shoot the "horse" and rush there.

Wang Yang found Xiaohong again and asked her to go over, but it might be helpful to send a message to her.

Xiaohong nodded and asked him what he was.
