Repair Record of Useless Human Equipment

A blacksmith who had lost his right hand picked up a piece of scrap metal from the ruins and built himself a machine hand. There lives an ancient fire phoenix in the iron. After being sealed for too long, he forgot who he was and had a bad temper. He often called him "mortal" and reluctantly agreed to help the blacksmith control the fire to pay the rent. At first life was manageable. Later, the monk came and said that this hand was black iron and wanted to take it away. The blacksmith didn't give it. The monk started to grab it, but the blacksmith blew up his right hand and ran away with the fire phoenix. Now he wants to use a bunch of leftover materials and black ore to rebuild a hand - better and tougher than before. Even Fire Phoenix can't see through the limits of this hand. He also had to search for minerals in the mountains, skin snakes, grind snake bones, and, under the eyes of more and more monks, beat an iron hand into something that even the monks could not understand. No big goals. I just broke a hand and wanted to get it back. It's just that there's someone living in her right hand, and he doesn't want her to be imprisoned again. "Mortal, are you going to explode again?" "It won't explode. We'll weld it together." "What did you weld?" "You'll know then."
