A large amount of tin ore was transported to the Karazhan tribe. These tin ore containing a lot of impurities need to be smelted.

Because the melting point of tin is extremely extreme, a little melting can separate the tin water from the rock.

Right now, the development of Stormwind City is all stuck in the bronze. Without the right tools, it is impossible to open up wasteland and dense forests quickly.

The construction of 　　 kilns and thatched huts have never stopped. The savages are very diligent and built 9 huge kilns in just a few hours. The flames at the bottom of the kilns are burning.

The trees, shrubs, and weeds outside the dense forest are being quickly consumed. It is painful to work in the sun because the sun is scorching hot.

Standing under the scorching sun for a few hours, they could peel their necks in the sun, and some carpenters began to make the pergola, using a relatively sturdy tree as the foundation, and embedded one end of the tree deeply in the soil.

The tree trunk is more than 3 meters out of the soil, and then the beams are **** with vines, and then a large number of twigs and weeds are covered on it.

Pergola can not only enjoy the cool, but also shelter from the rain, because the texture of the kiln is mud, which will be washed away by rain for a long time.

In this way, 200 people have been busy working until the afternoon, and all the red copper and tin ore on the tribal clearing are completely decomposed.

The method of decomposition is still smelting. You only need to put the whole piece of red copper ore into a huge refractory container, and then ignite it to start firing. The temperature reaches more than 700 degrees, and the stone and other high-temperature impurities are perfectly separated from the red copper.

At this time, pour the red copper water into the clay pot, wait until the red copper has cooled and solidified, and then smash the clay pot.

Tin ore is also smelted in this way, but the amount of tin is far less than that of red copper.

a total of more than 2,000 catties of tin ore, and finally only more than 300 catties of tin alloys containing impurities, these metals may contain aluminum or lead.

But these don’t matter, as long as there is tin and red copper, and the two are in a certain ratio, you can make bronzes with barely toughness and hardness.

Of course, this is what Zhao Yunxiang thought, because he does not have lead, and there is no guarantee that the toughness will be at the same time as the hardness reaches the standard.

"Lord, do you want to start now?" Several smelters came over and they were in charge of metal smelting.

"Well, let's start smelting. First, make a batch of bronze axes and picks. Of course, you have to make some saws." Zhao Yunxiang said, "The top priority is that we must first organize the site."

The axe can cut down small trees, the saw can cut off the big trees, and the pickaxe can clean all the deep-rooted plants.

There are about 100 adult males in the tribe, and they can evenly distribute bronzes such as axes, while the remaining women and children help weeding weeds...

In the night!

Zhao Yunxiang squatted in front of the fire, the flames swaying in the cool breeze set off his angular, heroic face, and of course, the huge dinosaur behind him.

He is making his own weapons, from the initial smelting, casting, sharpening, and now carburizing.

The fact that the bronzes are not forged is basically smelted, just because he does not have lead, and the bronzes combined with tin and red copper alone, I believe they will break within a few hammers.

carburizing process makes the metal harder, leaving a carburized layer 1 cm thick on the skin. This carburized layer is very smooth and can remove a lot of burrs.

Of course, there is quenching after carburizing, and the hardness after quenching will greatly increase.

"I don't know if the carburizing of bronzes has any effect..."

Zhao Yunxiang fiddled with the fire with branches, two daggers and two daggers were covered under a large amount of charcoal.

Zhao Yunxiang is an assassin, probably due to professional reasons, that makes him like this short blade very much, mainly because the bronze machete is not very easy to use.

"I still miss the machete from before!"

The carburizing is over. Carburizing still has a great effect on bronzes. After carburizing, the short edge becomes very smooth and the burrs are reduced a lot.

looks like modern swords, mostly using carburizing process, this process makes the sword sharper.

"Finally done." Zhao Yunxiang looked at the sharp blade in his hand, the bronze dagger and dagger had a blue pattern, which was a trace left after quenching.

"Boss, what you made is so beautiful!" Xiaoqiang came over with a pickaxe, because of limited materials, he could only allocate this.

In fact, Xiaoqiang prefers big knives and the like, which is very powerful.

"It's okay, but I don't know how strong the toughness is." Zhao Yunxiang has tested it, and the vines of the wrist are basically cut with a single cut, and the cut is flat.

"Do you want to go out for a test?" Xiaoqiang thought for a while and said, "The jungle at night is terrible. Although there are no dinosaurs, there are still many terrible predators, and those big bugs will also come out."

The so-called big bugs refer to giant Malu, Bron poisonous scorpions and the like, because these things are too big and terrifying.

As for the overlord of this world, the dinosaur...

They are reptiles, they usually sleep at night, because there is no sun and no temperature at night, and their cold blood will cause slow movement.

"I won't go out for the time being, I might as well lie in a hammock and eat some fruit." Zhao Yunxiang made a hammock by himself, and the hammock was far away from the jungle and near the fire.

A place with fire will attract many moths, but there are few mosquitoes here. At the same time, because it is open and not far from the sea, the sea breeze makes it difficult for mosquitoes to fly smoothly in the air.

There are three kinds of fruits on the hunt now. One is grown on vines and tastes similar to apples and pears, the other is grape-like fruit This kind of fruit is very sour, and the other is light in taste. , Similar to cucumber, but looks like a cantaloupe fruit.

At present, these three kinds of fruits are non-toxic, and wild people have tested the edibility experiment by using Zhao Yunxiang's friendship.

Of course, I also tested a few poisonous ones. One kind of fruit is very delicious. It is the size of an apple. It tastes very crunchy and has plenty of juice, just like a watermelon. It's a pity that this kind of fruit is very toxic.

There was an old man who was recruited. He didn't talk about diarrhea, but it was very itchy. The old man probably scratched it.

Although it is night, there are still many savages working. They happily open up the wasteland, pushing trees 40 meters high, all thanks to the bronze saw and big axe made by Zhao Yunxiang.

Similarly, those wild men with pickaxes dug out the roots of the big trees. These big trees are very deep. The wild people excitement digging 7 meters deep are useless. They still use a saw to cut the roots of the tree. Get out the huge pier.

Of course, huge piers are also useful, and the savages discussed making a table.

That's right!

is exactly the idea that Zhao Yunxiang promoted the carpenter savage, and he just cut off a few roots of the tree roots and made a table with a diameter of 8 meters. .

"According to this momentum, it won't be long before the entire jungle will be cleaned up." Zhao Yunxiang thought for a while and said, "While we get a large area of ​​land, we can also harvest a lot of wood and plant fruits or seeds. Of course... It disturbed the hidden animals in the forest."

"Uh..." Xiaoqiang felt that Zhao Yunxiang was right, and didn't know how to answer him for a while, so he simply said a phrase he often said, "Big guy is awesome!"
