"I-i did it~" Kyle panted, beads of sweat streaming down his body as he stared at the sword in front. There was a mixed expression plastered on his face, as his hands were trembling greatly the hammer still clutched in his hand. 


"Well done boy.. I had my doubts, but looks like you ain't all bark and no bite afterall." Darwin smiled inspecting the sword. When Kyle had watched Darwin, he concluded it to be easy as he hadn't know how swords were made, so he thought it wouldn't be difficult. 


Picking the steel he placed it on the table, heating it in the burning furnace. Carrying it out after a while, and placing it on the anvil used by Darwin. 


'The flames would be my only challenge.' Kyle thought, wiping some beads of sweat off from his forehead. He still didn't know how Darwin was immune to this burning flames, but he'd guessed the latter might be used to such environments, since he guessed he was a weaponsmith.
