One sword stirs the winds of the age; one blade appears, and the world is shaken. In a coffin, he quietly watches the moon pass through a thousand autumns; in his dreams, he crosses the nine heavens. Chaos never ends, and blood bathes the immortals. Through tens of thousands of years of madness, countless divine weapons descend into the mortal realm, and the ancestral catalogue of weapons appears from the sky, turning the world upside down.
