At the end of the Warring States Period, my soul pierced a piece of bronze and was forged into a sword by the enemy. I awakened the "weapon memory" system, which can copy all forging techniques I have come into contact with. Three days later, at the enemy's celebration banquet, I was hung by the general around his waist to show off the spoils of war, while I silently carved the gunpowder formula to the blacksmith of my homeland. They were chatting and laughing, and I was talking secretly.
