Four Hundred Years of Rusting Iron, Forging a Fierce Edge Again

I am a piece of iron. A piece of rusty iron that has rotted in the darkness for four hundred years. I was once a green man, carrying the ambition of a hero and blooming with the edge of a fierce general. I drank the blood of Guandu, burned the fire of Chibi, heard the wails of millions of dead souls, and witnessed the long sigh of the Three Kingdoms when the troubled times came to an end and the world returned to Jin. The city of Chengdu was broken, and it collapsed on a rainy night. I broke into pieces and fell into the earth, but my remaining soul remained, watching the changes of dynasties and the rise and fall of the world, and stayed dormant for four hundred years. Once it was unearthed, it was already the golden age of Zhenguan in the Tang Dynasty. Burning me in the furnace fire, forging me with a thousand hammers, the world thought they were forging a magic weapon, but little did they know, they just awakened a sleeping beast. The violence of the old days and the refined steel of the new dynasty are entwined in my bones and blood. Since then, a fierce blade spanning four hundred years has appeared in the prosperous Tang Dynasty. In the next thousand years, the Xuanjia Army marched to Mobei, carried the Wei Army to fight against the powerful, defended the country with sharp blades, and suppressed troubled times with iron blood. The sharpest divisions of the past dynasties all use me as the vanguard; all the flames of war and smoke from thousands of miles away are consumed by my blade. The world regards me as a divine soldier who can conquer the country. From beginning to end, I was just a monster that had lived for a thousand years, was used to seeing life and death, and had never killed enough. Whenever foreign invaders invade the territory, I will unsheath them; Whenever trouble comes, I will be the king. Although the fire in the furnace is extinguished, my fierce flames will never be extinguished.
