Primitives are stunned

Chapter 216 Copper Smelting Furnace

"The first point is that although the evil god is powerful, it is not omnipotent. If calculated from its energy fluctuations, it may need to accumulate enough energy for three months before it can use the moon as a force on a full moon night Clear up a wave of brain domain knowledge for us.

Therefore, as long as we resist this wave of attacks every three months, it is enough.

The second point is that the reason why it needs to accumulate enough energy for three months is not to target us according to my analysis, but to break open the monument protecting us in the village.

Just like those savages, without the protection of the stele, they will forget everything in a short time and rely only on biological instinct to survive.

The third point, and the most important point, I analyze, once the village is upgraded to a third-level tribe, then our village will not only have no limit on the number of people.And I think that the protection of the stele will definitely increase greatly. I am afraid that the evil god will not be able to erase our memory at will at that time. "

After listening to Gu Mu's analysis, everyone couldn't help but feel chills all over their bodies.They never imagined that above them, there was such a powerful existence that radiated infinite malice towards human beings.

Fortunately, there is an ancestor god who blesses mankind with the help of the stele.Otherwise, everyone couldn't help but shudder when they thought about those savages who were like wild beasts with only survival instinct left.

Only Wang Hu had a bewildered expression on his face, as if he was listening to a scripture from heaven.

In fact, Wang Hu is not very stupid, but after the exchange day, he found that there is no place for him to think about in the village. As long as he follows Wang Hao and listens to Wang Hao's words firmly, then There is absolutely nothing wrong with that.

As the saying goes, your brain will rust if you don't use it.Wang Hu is like this. He works his muscles all day long, but his brain is getting weaker and weaker.

If Gu Mu's words spread widely, it might cause panic. Therefore, Wang Hao issued a gag order that everyone present must not spread this matter to the outside world.

According to Gu Mu, the use of energy in the brain area is very exhausting. He fought a battle with the evil god in the brain area last night and needed a long period of recuperation to recover.

Therefore, during this period of time, he has no way to take care of the affairs in the village.

Reluctantly, the trip to the Black Forest to find asphalt was postponed again by Wang Hao.

But it just so happens that the construction of the copper smelting furnace has come to a critical time recently.

In the eyes of outsiders, brick firing should be the most precious technology in Wangcun.It is a magical ability to turn the useless soil that can be seen everywhere into stones that can be used to build houses and repair ditches.

It's just that Wang Cun doesn't seem to know how precious this miraculous ability is.

Anyone from outside the village can find an excuse to visit the brick kilns when they are not busy.

The defense on the side of the brick kiln is even looser than the defense on the side of the textile house. It can even be said that there is no defense at all.

In contrast, the copper smelting furnace on the other side of the village, which is completely useless in the eyes of the people in the wilderness, can be called heavily guarded.

If it is said that the brick kiln burns clay into stones, then the copper smelting furnace belongs to the burning of stones into soil.

The Great Wilderness lacks everything except mud.After these outsiders heard about the secret of the copper smelting furnace, they couldn't figure out why Wangcun spent so much effort building such a useless thing.

The entire copper furnace is like an upright oval shell.It's just that the top quarter of the shell was flattened by someone.

The copper furnace is huge, more than four meters in diameter.But if you know that its furnace wall is a full meter thick, you will know that its interior is not very big.

The copper furnace with a large belly and slightly pointed ends is like a watermelon on the earth. The entire copper furnace is divided into three layers.

The outermost layer is about one foot thick soil, mainly for heat insulation.

The middle layer is a brick layer made of clay and lime. Such a thick brick layer, even if it is a rhinoceros, cannot knock it down, mainly for the sake of strength.

The innermost layer is clay about a foot thick.The compacted clay is not only extremely hard, but the most important thing is that its melting point is at [-] degrees.

The melting point of copper is 83 degrees, and the temperature of an open flame in nature is only [-] to [-] degrees. However, in a sealed copper furnace, if you use charcoal fire and blow it with a blower, the temperature can even reach [-] degrees.

Such a temperature can not only melt copper ore, but even ordinary soil may liquefy it.Only a thick layer of clay can block this high temperature.

In fact, as long as the thickness of the copper smelting furnace is one foot thick, it can block the high temperature. However, Wang Hao is born with a sense of fear of such sealed high-temperature objects.Just like when he was a child, he was always worried that the pressure cooker in his home would explode, so he tripled the thickness of the copper stove.

Four round holes are left on the four sides of the copper furnace.

Outside the round hole, there are four newly fired pottery pipes extending obliquely downward.

At the end of the half-meter-long pottery pipe, a wooden bellows was connected with animal skins.

The entire bellows is about one meter long, and it is a boxy wooden bellows similar to a pump.

There is a T-shaped handle at the end of the bellows, pull it out, and the air will enter the bellows through the reserved hole.

And once you press it down, that air is forced into the front end.

Although this kind of ancient bellows is laborious to use, for the people in the wilderness, what they need most is a handful of strength.

Enough charcoal is put into the bottom of the copper furnace, and under the action of the blower, the temperature in the furnace can exceed [-] degrees.

The crushed copper ore accumulated on the charcoal will turn into copper water at such a high temperature, and then sink to the bottom of the furnace.

Normally, the melting point of the slag left over from copper smelting is higher than that of copper.Fortunately, Wang Hao knew that lime could be used as a combustion aid for slag.

The density of copper is very high, whether it is the waste slag after the melting of copper ore, or the ash left after burning charcoal, it is not as heavy as it.

Therefore, the melted copper water always sinks to the bottom of the copper furnace.

The remaining slag will float on the copper water.Just like water and oil put together, they can be divided into two distinct layers after precipitation.

Right below the copper furnace, there is a copper outlet reserved.The copper outlet can be controlled by a valve.

In order to facilitate the clansmen to use clay pots to receive copper, a large pit of one meter cubic was dug out under the copper outlet.

When the copper furnace was built, Wang Hao calculated the manpower needed for copper smelting.

From top to bottom, a person is needed to feed the copper furnace from the feeding port reserved at the top and take care of the waste gas hole.

Two to four are required to control the blower.

Need a valve to control the copper outlet.

We also need a clay pot for copper water and a slag handler.

Calculated in this way, just to smelt a furnace of copper, a full six to eight people are needed.

Among them, the only ones who can be replaced by wildlings are the one who blows the wind and the one who adds food.

And the labor extended from copper smelting.

For the time being, Wangcun doesn't need to worry about transporting the copper ore. Liucun wants to fill his stomach, so he will naturally deliver the copper ore on time every month.

But burning charcoal needs to be done by Wangcun people themselves.And if you want to burn charcoal, you need a lot of firewood, which in turn requires manpower.

Of course, if the giants are allowed to log, one can be used by ten people, but the giants still have more important things to do, and that is to crush the copper mines.

It is impossible to melt the entire piece of copper mine with Wangcun's current local methods.Therefore, the copper ore must be ground into powder.

A two-meter-long earth pit was dug out, and the most solid bluestone slabs in the wilderness were placed under the earth pit.The surroundings of the pit were built with bricks.

A pile of copper ore was pushed into the soil. At this time, the giant could use his hammer to strike in the pit.

The copper mine, which was not very strong, was smashed to pieces by the giant.

And those splashed gravels will still fall into the pit after hitting the pit wall made of masonry.

It is not difficult to smelt copper.If you want to learn, any tribe can learn it.

However, its impact on the future of the wilderness is extremely huge.

Not to mention anything else, if metal arrowheads are added to the arrow shafts, more than ten strong bows are fully capable of shooting second-level creatures.

The production process is simple, and if iron nails that can be mass-produced come out, before the brick houses can be built, they can lead people to build some breathable, bright, and moisture-proof wooden houses.In this way, dried fish will not be spoiled by moisture every day because it is stored in the hut.The carpenter's skills have not yet been mastered, and now it is impossible to build a wooden house that can be tightly clamped without a single nail.

The shovels produced by the system will no longer be in short supply in the village. The sowing season is coming soon. There are more than ten kinds of plants identified by the system that are edible and can be used as dishes. Now they can be planted, but because There was not enough reclaimed land, so Wang Hao had to postpone their planting plan and leave those few lands for wheat.

Therefore, because of these various reasons, the whole process of copper smelting must be controlled by one's own tribe.Although savages who don't know anything, can't speak, and can only rely on some simple commands and imitations to work can complete most of the work, after calculation, Wang Hao found that it takes at least five years for the core part to practice a furnace of copper. members of one's own clan to participate.And that's not counting the soldiers on guard around them.

To refine a furnace of copper, in addition to more than a dozen savages who can do coolies, five clansmen who can rest assured are also needed.

For such a stove, Wang Hao needs to build at least three.

Of course, these three furnaces are not all copper furnaces.

You must know that copper is not hard, and the hardness of copper produced by this method is not even comparable to that of stone.
