Nine thousand years ago, the Emperor of Immortal Martial Arts led a million divine generals into the ancient chaos, but none returned, leaving only a thread of true fire in the world. Nine thousand years later, Ye Chen, a discarded disciple of his sect, was expelled from the sect and had nowhere to go. By a stroke of luck, he obtained the true fire and began his journey on the path of Immortal Martial Arts. This is a world where gods, demons, immortals, and buddhas coexist, a chaotic era of myriad realms. Ye Chen's heaven-defying quest begins here.
