Lucio looked at Kai, who was hammering away on a piece of metal that was glowing bright red and turned towards the bulky man who looked at Kai grumpily.
He stood there silently as he watched Kai work, trying to learn something from his actions.
He understood the basics of weapon making and the fact that it involved taking a piece of metal and heating it up to a required temperature to be able to change its shape by hammering it constantly until the temperature of the metal fell.
After which the cycle of heating and hammering repeated until the desired shape was formed, after which it would be quenched in either water or oil.
Kai took out a small blade from the quenching barrel that could easily be called a top-notch dagger if he fixed a handle to it. He showed it to the muscular man who snorted before packing his things and leave the shop as he bumped Lucio's shoulder angrily.
Lucio ignored the man and looked at Kai, "What just happened?"
