After thousands of years of reincarnation, a ray of sword soul reincarnated into another world and turned into a useless prince. When the memory of the modern warrior king awakened, and his talent for magic and martial arts awakened, he used his sword as a pen to compose a heaven-defying war song in another world. From a small border country to all the worlds, slaying gods and demons, stepping on the sky, and finally becoming an emperor, dancing with swords and singing, all the worlds bow their heads!
