Wang Qiang is not interested in the boring textbook knowledge of his student days, and he can't remember much now, most of Wang Qiang's knowledge comes from novels, games, film and television dramas that he is interested in.

How famous is Daye? Jiangnan cornucopia, open-pit copper mine, Chu State jumped from a small country to the largest capital of the Seven Heroes of the Warring States, and Zhang Zhidong, the governor of Huguang in the Qing Dynasty, is still here to make steel in an attempt to reverse the national fortune of the Qing pill!

This is not a game, but Daye's place itself is the earth is hanging, and this is a treasure land! Compared with the discovery of the treasure land, the origin of the big lake in the distance is not important, the geographical environment of the prehistoric era is definitely different, Qinghai Province was still a vast West Sea at the time of the Three Emperors and Five Emperors.

Wang Qiang once again remembered Su Su's serious sentence yesterday that "the greater the difficulty, the greater the gain", and finally understood the significance of his opening in this location: the so-called highest difficulty start is not to throw the player in a desert where there is nothing, and that kind of high difficulty is meaningless. I have the task of killing the virus, and I must have the capital to kill the virus no matter what, it depends on whether I can grasp it.

I have to say that the snow covered by the mountains, plus the layer of moss covered by the ore, is really eye-catching! And when it came to moss stones, Wang Qiang suddenly remembered that the soil cave he started with, and the soil cave of the oxygen tree, didn't there be this kind of moss stone?

If they are also copper mines, then they are directly in the copper mine to start, but they were forced to be confused for two days before they found out, this is a fart super player! Thinking of this, Wang Qiang's heart congestion can no longer be described as regretful!

Calm down! Being a super player is to race against time to use all your time to do the right thing, even if it is the free time when you are hunted down, so the right thing now is undoubtedly to smelt the copper!

But copper smelting...... At this moment, Wang Qiang misses his chemistry teacher in high school very much. High school is the peak period of knowledge in a person's life, learn high school mathematics, physics and chemistry well, and travel through the past and the present are not afraid! If only I had known that I would have crossed over one day...... However, at least I've played games for fun and education, and I'm a grandmaster-level miner, forger, and strengthener in countless games!

In most games, Copper Ore is an entry-level forge, and you can simply throw the ore in the charcoal furnace of the blacksmith shop and burn it, without the need for an iron ore blower. Because the melting point of copper is very low, it can be burned into copper water and flow out at too high a temperature, and then a copper vessel is made with a clay mold. Of course, this copper is not pure copper, it is bronze containing other metal alloys in the ore, bronze has a low melting point, is harder than pure copper, and is more suitable for weapons.

The evolution of human civilization from the Stone Age to the Bronze Age is nothing more than an accidental discovery made by prehistoric humans after eating barbecue on a copper ore rack fire. So it's impossible to be as confident as a prehistoric human who eats barbecue!

I have also worked hard in the college entrance examination, high school chemistry has not all died, the wet copper smelting formula is returned to the teacher, and the fire copper smelting formula - I can't remember, but the principle is very simple, not just burning!

Charcoal! Yes, charcoal! Just like the blacksmith in the game to lay a charcoal stove, charcoal not only burns at a higher temperature than firewood, but more importantly, charcoal itself is also an important reducing agent, and only by burning with charcoal can copper and iron ore be reduced to copper and molten iron. And charcoal is the product of incomplete combustion of wood, burning wet wood is easy to burn charcoal, in short, is to continue to cut down the tree, the firewood pile continues to heighten, compact, smoldering!

So Wang Qiang picked up a green stone and said excitedly: "Ah Duo, we have found Baoshan, let's pick up more of this stone, and then burn it with a fire, and then a treasure called copper can appear!" Copper can be used to make stronger weapons or tools. ”

Ah Duo said with novelty: "Can the stone be burned? Do stronger weapons? Crossbow? ”

"Copper crossbow?" Wang Qiang was quite embarrassed and said: "It's too fine, we don't have enough tools, we can try to make an axe first, a copper axe!" Much more powerful than this stone axe. ”

Ah Duo excitedly swallowed a few bites of meat and said, "I knew that the chief was a god...... Otherwise, how could I know such a miraculous thing, I'll go pick up the stones right away......"

Wang Qiang also couldn't cry or laugh, how embarrassing would it be if his brother failed and didn't burn copper? However, the pine tree has more fire power than pine oil, so it should be burned out, right? The key is whether there is enough time? The enemy is two days away on foot, and even if they set out early in the morning, they will not be able to come until noon or even in the afternoon, right?

If it's afternoon? Wang Qiang's guerrilla idea of attracting monsters has been perfected again: if you come in the afternoon, won't you stay up until dark if you delay it? Wouldn't it be dark and have a good chance of escaping the other party's pursuit? Perfect! I really didn't think about how to get out in detail before, after all, there must be a way before the horse reaches the mountain.

Wang Qiang was excited, and he also finished eating bear meat in two bites, and overcame the soreness of his body to continue to work with the supreme energy of discovering rare divine mines in the usual games.

Soon, a half-human-tall pile of green stones, large and small, was collected. It's just that this appearance doesn't feel very good, right? Modern smelting should have a special ore crusher, right?

Then smash! Smash as much as you can!

So Wang Qiang and Ah Duo hammered each other with ore and ore, and the palms of the smashed hands were painful and their arms were numb, and the effect did not seem to be very good.

Wang Qiang further realized the helplessness of backward productivity, but the more backward he was, the more determined Wang Qiang was to refine copper. As long as the copper water is refined, even if it is condensed into a pile of irregular copper blocks, it can at least be used to smash ore!

But Wang Qiang already had the experience of shaping the crossbow body in Huang Ni yesterday, so it was impossible to be particularly irregular.

So the next step is for Wang Qiang to bury the stone axe in his hand directly into the soil to make a mold, which is the ground mold casting method - it has nothing to do with high school and college level, just be able to play. As long as the copper water melts out and flows into this mold, the copper axe is born, but this is ideal, because Wang Qiang cannot control the flow of copper water in this fire. Then simply print a circle of axe molds around the fire.

In short, the first copper smelting, or the collection of copper blocks, in the future, there is a chance to burn a standardized ceramic furnace, and then use the ceramic furnace to melt the copper blocks to re-standardize casting, and then to burn charcoal to further improve the process. At that time, it will not be such a simple thing as casting a copper axe, and you will directly get a copper crossbow!

When he thought that the future was so beautiful, and he might not be able to survive today, Wang Qiang regretted that he shouldn't have done it in the first place! How sad is this life that can't be reversed? Can you give my brother a chance to regret it? Brother is independent and does not inherit the so-called predecessor's inheritance, he is a loser......

When all the collection preparations were in place, Wang Qiang and Ah Duo threw the broken ore into the fire, and then they kept collecting firewood and burning firewood.
