In 1271, Emperor Huan Li of the Yuan Dynasty met an old man while hunting. The old man told him that your dynasty will eventually fall. Not far from the streets of Chang'an, a young man was sitting alone on the street with a square-shaped painted halberd on his back. At this time, two more young men came, and in the end no one survived. This begins the fictional story. This story is the first work by Dawn author. Also due to my lack of experience, please bear with me.
