Large quantities of tin ore are transported to the Karazan tribe, and these tin ores containing large amounts of impurities need to be smelted.

Because the melting point of tin is polar, a little melting can separate the tin from the rock.

Now, Stormwind's development is all stuck in the bronze, and without the right tools, it is impossible to quickly open up the dense forest.

The construction of kilns and thatched huts never stopped, and the wild man was very diligent, and in just a few hours he built 9 huge kilns, and the flames at the bottom of the kilns were burning.

The trees, shrubs, and weeds on the periphery of the jungle are being consumed rapidly, and working in the sun is painful because of the scorching sun.

After standing in the scorching sun for a few hours, some carpenters began to make pergolas, using sturdy trees as foundations and embedding one end deep in the earth.

The trunk of the tree is more than 3 meters above the soil, and the beams are tied with vines, and a large number of thin branches and weeds are covered with it.

The pergola can not only enjoy the shade, but also provide shelter from the rain, because the texture of the kiln is earth, which will be washed away by rain for a long time.

In this way, 200 people worked until the afternoon, and all the copper and tin ore in the tribal clearing was completely decomposed.

The method of decomposition is still smelting, only the whole piece of red copper ore is put into a huge refractory container, and then ignited 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, you can pour the red copper water into the jar made of clay, wait until the red copper cools and solidifies, and then break the clay jar.

Tin ore is also smelted in this way, but the amount of this tin is nowhere near as high as that of red copper.

More than 2,000 catties of tin ore were finally smelted into more than 300 catties of tin alloys containing impurities, which may contain aluminum or lead.

But these don't matter, as long as there is tin and red copper, according to a certain ratio, you can make a bronze with barely enough toughness and hardness.

Of course, this is what Zhao Yunxiang thinks, because he has no lead, and there is no guarantee of what the toughness will be while the hardness meets the standard.

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

"Well, let's start smelting, make a batch of bronze axes and pickaxes, and of course some saws. Zhao Yunxiang said, "It is imperative that we first sort out the territory." ”

An axe can cut down a small tree, a saw can cut off a large tree, and a pickaxe can remove all the plants that are deeply rooted.

There are about 100 adult males in the tribe, and they can divide the bronze objects such as axes equally, and the rest of the women and children help pull weeds and so on......

Night!

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

He is crafting his own weapons, from the first smelting, casting, sharpening, and now carburizing.

There is no such thing as forging bronzes, they are basically smelted, just because he has no lead, and it is believed that the bronze objects combined with tin and red copper will be broken after a few hammers.

The carburizing process makes the metal harder, leaving a 1 cm thick layer of carburizing on the skin, which is very smooth and removes a large number of burrs.

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

"I don't know if the carburizing of bronzes has any effect......"62

Zhao Yunxiang stirred the fire with a branch, and under the large amount of charcoal was covering two short swords and two daggers.

Zhao Yunxiang was an assassin, probably because of his profession, which made him like this short blade very much, mainly because the bronze machete was not very easy to use.

"I still miss the machete before!"

At the end of carburizing, carburizing still has a great effect on bronzes, and the short blades after carburizing become very smooth, and the burrs have become much less.

Like modern swords, most of them use the carburizing process, which makes the sword sharper.

"It's finally done. Zhao Yunxiang looked at the sharp blade in his hand, the bronze short sword and dagger had a blue pattern on it, which was the trace left after quenching.

"Big guy, this one you made is so beautiful!" Xiao Qiang walked over with a pickaxe, because the materials were limited, he could only be assigned to this.

In fact, Xiaoqiang prefers big knives and the like, which is very effective to slash and kill.

"It's okay, I just don't know how strong the toughness is. "Zhao Yunxiang has tested, and the vines with the thickness of the wrist are basically cut off with a knife, and the incision is smooth.

"Do you want to go out and test?" Xiaoqiang thought for a while and said, "The jungle at night is terrifying, although there are no dinosaurs, but ...... There are still a lot of terrible predators, and those big bugs will come out too. ”

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

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

They are reptiles and generally sleep at night because there is no sun at night, there is no temperature, and their cold blood can cause sluggishness.

"I won't go out for the time being, so I might as well lie in the hammock and nibble on a fruit to eat. Zhao Yunxiang made a hammock himself, far away from the jungle and close to the fire.

Where there is fire, it attracts many moths, but there are few mosquitoes, and because it is located in an open area, it is not far from the sea, and it is difficult for mosquitoes to fly smoothly in the air when the sea breeze blows.

Now there are three kinds of fruits, one is a fruit that grows on the vine and tastes like apples and pears, one is a fruit that resembles grapes, which is very sour, and the other is a fruit that has a light taste and is similar to a cucumber but looks like a cantaloupe.

At present, these three fruits are non-toxic, and the savages have tested them using Zhao Yunxiang's edible experiments.

Of course, a few poisonous ones have also been tested, and there is a kind of fruit that is particularly delicious, the size of an apple, very crisp to eat, and rich in juice, just like watermelon, but unfortunately the toxicity of this fruit is very fucking.

There was an old man who was tricked, not to mention diarrhea, and it was very itchy, and the old man was probably scratched.

Although it was night, there were still many wild people working, and they were tireless in opening the wasteland, pushing trees more than 40 meters high, thanks to the bronze saws and big axes made by Zhao Yunxiang.

In the same way, the wild men with pickaxes dug out the roots of the big trees, and these big trees were so deep that the wild people excitedly dug 7 meters deep to no avail, or deliberately sawed off the roots with a saw to get the huge pier out.

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

That's right!

It was the carpenter savage who Zhao Yunxiang promoted came up with the idea, and he just cut off a few root systems of the tree roots and made a table with a diameter of 8 meters.

"At this rate, it won't be long before the entire jungle is mined. Zhao Yunxiang thought for a while and said, "While getting a large piece of land, we can also harvest a lot of wood and plant fruits or seeds, of course...... It will also disturb the animals hidden in the forest. ”

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