The blacksmith explains that if he hadn't been seeking revenge, he would have become a blacksmith and made a lot of money. He explains that he's only been eating a tiny amount of food, which is fine, since he doesn't have much else to spend his money on. He also says that he studied math and metallurgy when he was still on the earth, but that there aren't many applications for those fields in the sky city, where there are so many warriors. The blacksmith says that the fighting skills he learned in the dwarf village will be useless in a place like this, where weapons are so important. He says that weapons can tell you a lot about someone's status, and that's why they're so important in the martial arts era of this time. He's also worried about the quality of the sword, since it's made of iron and smelted in such a way that it would take him a long time to make it. He wants to know why he bothered to buy the iron blocks and the stove when he could just buy a better one. He asks the blacksmith to help him start the fire, and the blacksmith promises to make him a better sword later. He tells the blacksmith that he needs to get his skills back, so he can forge more swords. He promises to give the blacksmith a good sword later, and then he'll make him one of the best swords ever.
