The copper hammer opened the animal skin pocket, took out a handful of strange things from it, and threw it into the furnace, which looked clearly like mushrooms everywhere in the crypt, Xi Wenming couldn't help but ask curiously: "Teacher, are you hungry? I still have some dried meat here to satisfy my stomach!"

The copper hammer flushed, and said in a low voice: "These mushrooms are not used to eat, but to reduce the melting point of the ore, the internal temperature of the furnace can reach thousands of degrees, and the melting point of the ore is about this temperature, adding these black line mushrooms, the ore is easier to turn into liquid, this is the secret of our clan's copper smelting, you just know it yourself, don't spread it!"

Only then did Ji Wenming understand that these black line mushrooms were not used to eat, but used to smelt ore, and sure enough, with the addition of black line mushrooms, the surface of the ore in the furnace gradually melted and turned into half a pot of liquid.

Ji Wenming opened his mouth and asked, "Master, what is this furnace made of?

The copper hammer smiled: "But it is not magic gold, but an ancient Taishi mud, it is said that the Taishi mud existed when the universe was first formed, which contains the initial Taishi runes of heaven and earth, so it is called 'Taishi'." The furnaces of our hill dwarfs are all made of that kind of primordial mud, and then mixed, shaped, and incinerated to finally fire into the shape of a furnace, which is harder than any magic gold, and more resistant to high temperatures, and will not melt at all. ”

Casting is really full of knowledge, just the materials and tools have opened the eyes of Ji Wenming, he has never had so much insight in the desolate world.

Speaking of which, the Xiahou clan is a branch of the water god Gonggong clan, because the Gonggong clan broke through the Buzhou Mountain, causing the Tianhe River to flood and flood, so it was executed, and the Gonggong clan was also divided, among which Kun Bo brought some people to leave the territory of the Gonggong clan, came to Chongshan, and settled here.

Subsequently, the emperor was instructed to control the water for many years, and the Xiahou clan developed more and more large, forming the current scale, but because of the Gonggong clan, the clansmen are very familiar with the water control, and they are like mountains across the mountains for the use of fire and smelting.

There is a Gonggong remnant soul seal in the sea of Jiwen's destiny, and it is also because he is a descendant of the Gonggong clan. Because the war between Gonggong and Zhurong affected the world, therefore, the descendants of Gonggong were unwilling to admit that they had such an ancestor, and they lived in seclusion under pseudonyms, and now there are only three clans that can be found, and Xiahou is one of them.

Ji Wen was determined to learn casting and enchantment, but also because he had been restrained by the Zhurong clan, the Xia Hou clan could not make great progress, and now that he had the opportunity, of course, he had to learn a new skill to help the clan make up for its shortcomings.

Under the guidance of the copper hammer, he pushed the bellows hard, making the furnace fire burn more vigorously, and the golden magic flame burned into a purple and blue color, and the ore melted at a speed visible to the naked eye.

After about two hours, the ore in the furnace had completely melted into liquid, and the copper hammer reached out to manipulate the block at the bottom of the furnace, revealing a hole the size of a bowl, and the crimson liquid flowed out and poured into the mold next to it.

This furnace liquid just filled the mold, and there was still most of the solution at the bottom of the furnace, but the copper hammer was discarded, and said to Ji Wenming: "The remaining part of the furnace is all the slag left by the decomposition of the ore, and the liquid on the surface is the magic gold liquid, which must be diverted and preserved, otherwise it will affect the quality of the earth demon copper crystal." ”

With that, he once again operated a mechanism to dump all the remaining slag from the furnace into the Earthfire, allowing them to be carried into the Earth's lungs by the underground dissolution.

Ji Wenming couldn't help but ask: "Master, this process needs to go through four processes: ore filling, melting, diversion, and solidification, and it doesn't seem to be complicated! Why can't we smelt twenty Earth Demon Copper Crystals in three days?"

The copper hammer sighed: "Do you think this is the end? The ore liquid we smelt will slowly cool down and turn into a primary coarse earth demon copper crystal, which also contains other magic gold impurities, and after it is cooled and set, it will have to be forged by us with a sledgehammer and under high temperature conditions to become a real earth demon copper crystal, and in general, it will take at least three hours to forge a piece of earth demon copper crystal! How can three days be enough?"

Ji Wenming roughly calculated, three days are about thirty-six hours, even if it is sleepless, it is indeed not enough time to cast twenty pieces of Earth Demon Bronze Crystal, and he couldn't help but bared his teeth and said, "Then can we modify the smelting process and speed up the smelting step?"

Copper Hammer said with a wry smile: "Good boy, it's a good thing that you are willing to use your brains, but the ancestors have been smelting and processing magic gold for many years, and this round of casting and refining has gone through many streamlining before it was finally finalized, but it is not as simple as improving it." ”

Ji Wenming frowned, and thought for a while: "But teacher, I really have some ideas, see if you can achieve it!"

The copper hammer was originally intended to teach a skill, but at this moment he didn't feel that it was a waste of time, but patiently said: "Okay, you can tell me your thoughts!"

Ji Wenming nodded and said: "I have three ideas, the first is to improve the furnace, the teacher's furnace is too small, it can only load thousands of catties of ore at a time, if you can make the furnace bigger, and load tens of thousands of catties of ore at a time, then you can complete the smelting task of twenty pieces of Earth Demon Copper Crystal in two times!"

The copper hammer said: "You want to expand the furnace tenfold, this idea was also conceived by the ancestors, but it takes more power to operate the furnace, and the size of the furnace is already the limit that I can control, and if it is larger, not to mention the difficulty of melting the ore, even if you want to melt the liquid to produce copper, you need to recalculate the design, and three days is not enough time." ”

Ji Wenming nodded and said, "I still have an idea, that is, to increase the temperature of the furnace, so that the ore will melt quickly, saving our time for casting!"

The copper hammer nodded and said: "You have said the key points in both methods, half of the work of the way of casting is in the manipulation of the demon flame, but the earth fire used in the casting of our hill dwarf demons is already one of the few high-temperature magic flames suitable for casting in the world, and it is not easy to increase the temperature!"

Copper Hammer's opinion on Ji Wenming has changed quite a bit at this moment, but I didn't expect this kid to really have ideas, he has only accompanied himself to cast the magic gold ingot once, and he has already mastered the key to the problem, but since it is a key link, it will be more difficult to improve, because the casting masters throughout the ages have all paid attention to these key links, and if they want to improve slightly, they may be able to do it, and it is easy to say it, but it is too difficult to do.

Copper Hammer didn't know that Ji Wenming already had ideas and ideas to solve the problem in his heart when he proposed these two key links.

Ji Wenming didn't directly expose the mystery at this moment, because he wasn't sure that his method was really feasible, so he said: "Teacher, in fact, I still have a bold idea! Since these spars are all extracted from the rocks and soil, I think, is there also an ore component in the earthfire lava magic flame that we use for casting and heating? It has been melted into a mineral liquid, and if it can be directly extracted and processed, wouldn't it be more troublesome?"
