Wang Yang wrapped the template in front of the bonfire with the wet animal skin, and slowly opened the animal skin in front of the onlookers.

What caught your eye was the dark yellow bronze ware inlaid in the template, which attracted everyone's exclamation.

They all know how it is that those stones, which are just green, change not only the shape but also the color when they go in and out?

Suddenly, they surrounded Wang Yang curiously and asked nonsense.

Wang Yang had also refined a piece of patina before, but that piece was too small, let alone any scale, and a small layer of copper was refined, and everyone didn't care at all, thinking that the green stone was burned out.

This time, they had seen every step, so they were extremely shocked.

I haven't heard of anything that can change the shape and color, but you must know that they burn white clay, and what comes out is white porcelain, and when they burn coffee, they make clay, and they burn out almost the same dark red bricks.

There may be a slight change in color, but the shape has definitely not changed.

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

Everyone is still very puzzled, the tin is right, but the color of the tin has 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 a little and no longer delve into this issue.

Wang Yang wiped his sweat lightly, the chemical knowledge in it was impossible to explain clearly, but he was still secretly proud. My own nonsense has gone to another level.

Soon, everyone was attracted by the different shapes of bronze objects. They all stepped forward to touch it and found that it was not very hot. And he poured it out, and looked at it by the firelight.

I saw that those bronze objects were shining brightly, and they were very beautiful.

But I just thought it was good-looking, and it didn't make much use, so I threw it aside and ignored it.

Wang Yang also took the initiative to inspect these bronze objects, and he picked up a dagger, which was like a thin flatbread...... Dagger.

Ahem, let's call it a dagger, because in Wang Yang's imagination. It was indeed intended to be made into a dagger.

But who knew that there was too much green stone copper juice on the dagger template, which overflowed the template, and as a result, a good dagger became a large copper cake...... Can't eat it yet!

He took other bronze objects and found them to be more or less imperfect, either overflowing or insufficient.

Wang Yang expected this, but he was not too surprised.

For the time being, he couldn't calculate the exact copper content of these patina, nor did he know the volume of a piece of patina, let alone the capacity of the formwork.

These need to be calculated precisely and rigorously.

Wang Yang knows the calculation formula of the road. Unfortunately, there are no measuring tools, whether it is a length measuring tool or other measuring tools, which are completely missing.

You want to make a perfect conversion. There are two ways to make no more copper in each piece of template.

The first one is to make a small opening at the critical point of the template. Let the excess copper juice flow out, just like the design of the sink. There is a small drain to keep the water from filling the sink.

This skill is very demanding. But it's good.

The other is to create units of measurement, which will establish the norm for many future tools, which is a far-sighted approach.

But there are many aspects that need to be considered, and in the case of imperfect hieroglyphs, it is basically impossible to generalize.

Either way, it's actually a very stupid and cumbersome way, and although it has its own ingenious principles, it is honestly not suitable for making it when you have nothing.

And Wang Yang also put these two methods behind him early and ignored them.

He has a better and simpler way to do it, as simple as a three-year-old.

As he said before, everything is difficult at the beginning because in the beginning, there were no other tools to use, but now that there are bronze tools, it is possible to make tools, which makes time very simple.

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

What can long pliers be used for? Under normal circumstances, it can be used to stir in the fire, and the sweet potato in the fire can be taken out.

But here, of course, it's a different story.

He's going to get going, and no matter how much he explains, he can't really use it.

But before he could start, he saw Xiaohong find him with a frown and tell him that she wanted to go to the forest.

Wang Yangxin was not here, and said casually: "Go if you want, don't play too long, and return to the prairie early." ”

Belch...... Xiaohong was stunned for a moment, and then said angrily that she didn't go there to play.

Wang Yangle, what else are you going to do besides playing?

Xiaohong expressed her thoughts in pictures.

In fact, one of the reasons for coming back this time was that he was going to look for Wang Yang, but when Wang Yang came back, he didn't need to look for it.

Another reason is that there are too many animals on the grassland, which attracts a very, very large number of wild beasts, and they often sneak up on the fauna, but fortunately, they basically do not succeed.

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

Again and again, they were repelled by everyone relying on spears and arrows, and they were not too arrogant.

It is a pity that the lethality of spears and arrows is extremely limited, and a large number of spears and arrows are not made of sharp stones, because the skills of polishing and processing are too high to be satisfied.

Therefore, most of the spears and arrows are sharpened wooden tips, which are completely dependent on the firing power of the spear thrower itself to cause damage.

Many wild beasts rely on the thick and hard fur of their fur, and if they are shot, they will not be hit too deep, and there is no danger to their lives, so they have the courage to attack in large quantities.

It was impossible for everyone to meet the attack, otherwise the other beasts around them would find a breakthrough and rush over.

Killing a few animals is a trivial matter, and it would be really fatal for fear of disturbing the fauna and running around.

So there is nothing to do about those beasts, so they can only turn a blind eye and let them rage.

It can be said that the most relied on to keep animals and groups safe is spears and arrows, but spears and arrows are slender and long, especially easy to break, and consumption rises sharply.

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

It's a pity that qualified spears and arrows are so easy to make, too thick spears can't shoot far, too thin spears don't kill, a good spear and arrows are more difficult to build than wooden spears.

Since the tribe entered the cultivation business, the spear and arrow aspect has entered a stage of stagnation.

This is not to say that spears and arrows cannot be produced, but that the current development rate of the tribe far exceeds the production rate of spears and arrows.

In the canyon, five spears and arrows a day are almost enough, and the number of damaged arrows is about three, because the population is small, and there is less hunting activity.

Correspondingly, there is less damage.

Later, when the population increased, there was more hunting, and naturally there was more damage, but at that time, agriculture had just been developed, so the main work of the people was still in the production of spears and arrows.

The more damage I have, the more I produce!

In this way, nothing went wrong.

When the focus was entirely on agriculture, everyone was cultivating wheat orchards, and later developing industries such as clay, and everyone was swarming to do this and that, and the production of spears and arrows basically returned to the old way of sufficient.

Actually, it's nothing, it's been a year since I returned to this old road, and there have been no problems.

Therefore, spears and arrows are used less and less, and they are only used for defense, but the beasts in the vicinity have already become sophisticated, and the human group of Zhilu Dao is very strong, and they all hide when they meet, except for a few stunned young people who also come up to look for death, everyone has almost forgotten what the spears and arrows are used for.

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

Not only that, but weapons, including wooden spears, are becoming less and less important, as the focus of people's lives is no longer on killing and hunting.

You don't have to play a game of life and death with the beasts, who bothered to produce a thankless weapon?

Until now, there was only enough weapon in the tribe for each person, what is this concept?

That is, everyone has a spear, they have a sharp stone knife, and then it's gone! It's really gone!

It's not that you don't produce, but it's very, very troublesome to produce! Zhang San's guy worked hard to produce except for the time when he burned charcoal.

But now the population of the tribe has increased several times, and the processing conditions have not improved, even if he does not eat, drink or sleep, he will not be able to produce.

It is conceivable that after a period of time, the population will break through again, and it will be impossible for everyone to have a wooden spear in their hands, and this number will increase over time.

After listening to Xiaohong's description, Wang Yang wiped his face, he really hadn't thought about it.

If it can continue to develop peacefully, the spear and arrow will naturally be reduced to a dispensable situation.

It is a pity that the recent frenzied development of animal husbandry has exposed new problems.

This era is not the world where you can't see half an animal when you visit a barren mountain in the future, this is the world where giant beasts are like clouds and wild beasts are crisscrossing!

Three steps and a small beast, five steps and a monster are not blown!

"Looks like a mistake!" Wang Yang touched his chin, his eyes flickered slightly, and followed Xiaohong to the warehouse, counted the spears and arrows, and found that there were less than a hundred spears and arrows left!

He asked Red how many spears and arrows it would take to shoot a beast.

Red drew a picture, and each beast had to shoot at least four or five spears and arrows.

"What a waste, what a waste!" Wang Yang told her that spears and arrows were in short supply recently, and that the news had passed that each beast should shoot one arrow as much as possible.

The goal is not to kill the beasts, but to scare them off with some color.

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

Wang Yang found Xiaohong again and asked her to come over, but she had to help herself pass on a message, which might help.

Little Red nodded and asked him what it was.

Wang Yang began to paint on the ground. (To be continued......)
