Pure copper is actually not suitable for making weapons. In the history of humanity, what was first used on a large scale was bronze.
And bronze is an alloy of copper.
When Austin was in high school in his previous life, reading chemistry, perhaps they detailed the chemical composition of bronze alloys, but after so many years, Austin has forgotten more than half of this knowledge.
Although he forgot most of it, that doesn’t matter. When he read about ancient people slting bronze, he was very curious about how those ancient humans incorporated those reactive tals into copper and how they slted those reactive tals.
At that ti, Austin went to check it knowingly, and it turned out that in ancient tis, when slting bronze, ancient humans often added so associated minerals from which copper was produced to copper ore. Those associated minerals were the necessary components to form bronze alloys. Furthermore, adding those associated minerals resulted in the bronze alloy having a lower lting point than copper, making it easier to refine.
As for what elents those associated minerals consisted of, Austin has mostly forgotten. Likely, those ancient humans did not specifically study the components of those associated minerals; as long as usable bronze tools could be slted, who cared what elents they consisted of?
Since he rembered that slting bronze required associated minerals, Austin naturally began to try and asked the Kobolds present to find other associated minerals in the copper mine.
Since the work of refining copper had started, Austin also found that Kobolds seed to have a remarkable talent for mining and finding ore. Perhaps in the future, when looking for other ores, a Kobold exploration team could be specially established?
With their prospecting talent, the Kobolds quickly found the associated minerals different from copper ore and sent them to the blast furnace.
During this nearly a month’s ti, the Dragon Nest beastn not only developed a specific thod for refining copper but also, according to Austin’s instructions, made a lot of copper material. Since there was copper material, Austin planned to directly put these refined copper into the fire, then add the associated minerals to the earth blast furnace for re-lting.
With the efforts of the beastn, after exerting great Kung Fu for more than half a day, they finally manufactured a pale yellow axe.
"Not green? Could it be a matter of the tal elents of these associated minerals?"
Looking at the newly made axe, Austin’s mind was full of doubts.
Although it wasn’t bronze, from the refining situation, the lting point did indeed drop significantly, so there shouldn’t be any mistake.
"Take it and try it."
Even though it wasn’t the bronze he imagined, Austin still told a beastman to try it out.
So a strong Kobold took the axe to a nearby tree and started chopping it down rapidly. To Austin’s surprise, this axe was sharper than the stone axe and more rigid. In no ti, a whole tree was chopped down, yet the blade of the axe showed no signs of wear.
"Your, your highness... we have succeeded!"
The Goblin Gulu, responsible for refining copper, looked at the axe with fanaticism, so excited that he was almost speechless. More than a month of hard work in this Copper Ore Base had previously resulted in copper that was unusable, leading them to believe they had failed.
But now, from this axe, they all saw the hope of success.
Austin didn’t speak. He took the axe, weighed it in his hand, and lightly flicked its surface with his claw, feeling it was not much different from the iron axes provided by the Dragon Nest tribe.
Although it wasn’t the bronze he imagined, its properties were similar to iron, and in this humid world, copper was better than iron since it didn’t require extra effort to prevent rust.
Actually, around the Dragon Nest tribe, all the tribes used weapons like wooden spears, stone hamrs, and stone axes. Austin had only seen iron weapons a few tis, like the iron axe in the hands of Lizardman Rodney and those seized from the Blood Claw Tribe branch, as well as the rcenaries’ weapons. It could be said that within a hundred miles, almost all iron weapons were in Austin’s Dragon Nest tribe.
All the beastman tribes living in the Kawa Great Forest were basically primitive civilizations of the Stone Age, with no foundation for tal slting.
"First, follow the previous proportions and make ten great swords. Don’t slack off with the remaining work; it’s best to continue experinting with refining these coppers."
Since these alloyed coppers were no worse than ordinary iron, he decided to forge ten great swords first for the Gale Foot experintal group of beastn to use for training. However, Austin rembered that the best copper alloy weapons were still bronze, so he instructed the beastn to continue experinting.
Over ti, the Dragon Nest beastn around Austin were also influenced by so modern thinking from Austin. The cultivation of non-toxic mushrooms in the mushroom houses, the innovative manufacturing in the workshop, the establishnt of the witch doctor treatnt system, and even the formation of iron block combat techniques were largely the results of Austin instilling variable experints, inductive analysis, etc., into the Dragon Nest beastn.
By continuously experinting with changing variables and synthesizing the results to find the optimal thod, Austin’s modern thinking kept expanding within the Dragon Nest tribe. Though these invisible things seed inconspicuous, the establishnt of various systems in the Dragon Nest tribe was based on this kind of thinking.
With this foundation of thought, Austin didn’t need to teach them hand-in-hand; as long as the task of improving copper alloys was assigned, the beastn would naturally experint and improve continuously.
"It’s best if we can produce bronzes. For now, bronze weapons are the most suitable for the tribe’s current situation, and when developed to a certain extent, bronze is no less than so steel."
Holding the axe in his hand, Austin thought silently.
However, what Austin didn’t know was that bronze was initially not green. Newly slted bronze was a golden yellow, and it turned green because after being buried in the ground for thousands of years, it constantly rusted and oxidized, forming a layer of verdigris on its surface. It was thus called bronze.
Therefore, it was essentially impossible for him to slt green copper from the earth blast furnace directly.
Austin spent several days at the Copper Ore Base, and with the collective labor of over a hundred beastn, they finally forged ten great swords, each successfully completed.
Afterwards, while Austin assigned the task of researching better copper alloys to the beastn, he also ordered them to produce so copper alloy armors and manufacture so production tools based on previous techniques.
Having issued his orders, Austin returned to the Dragon Nest tribe with these ten great swords.
