Born in a land devoid of spiritual energy, a young man inherits an undying flame and the Sword Intent of Annihilation at the heart of an ancient battlefield. From then on, he takes up his sword and embarks on the path to immortality. Starting out in a sect, he fights countless battles and crosses mountains and rivers, rising to prominence in a glorious age when the Five Emperors coexist. He even passes on the Way of Slaying Heaven to the innate spirits born of his homeland. But all things decline after reaching their peak. Extraterritorial enemies who refine the heavens and myriad worlds invade with ruthless force to devour this supreme plane. In the final battle, to protect the world behind him, he burns up his very essence and unleashes a sword strike that incinerates the Dao, dying among the stars. The enemies retreat, the golden age collapses, and the cosmos enters a long age of spiritual decline. All that remains is a lonely grave in a forbidden land, and the sword-bearers who spend the rest of their lives guarding it, passing down this mission through generations. In a silent era, they remember this undying epic, which began in obscurity and ended in sacrifice.
