Zhou Yuan, a casual cultivator, was betrayed by his best friend, deprived of his Dantian by his master, and thrown into the Cave of Ten Thousand Demons. He gnawed away at the demon core in demon bones and resentment for three hundred years, and became a half-demon body in the realm of Nirvana. When he returned, he carried the resentment of three thousand demon kings and smashed the Tianyan Immortal Gate to pieces with one palm. However, before Ling Daoxuan died, he sneered, "You are just a chess piece that breaks the game." Jiang Xuewei sensed that there were cracks in the ancient seal hidden under the ruins of the Immortal Sect. When Zhou Yuan discovers that his rebirth is actually a conspiracy to warm up the catastrophe, he must join forces with Chi Ya, and under the guidance of Liu Wushuang's relics and the white-browed crane, step into the real battlefield of immortals and demons - where erased myths are buried and the key to subverting the Three Realms is hidden.
