Xie Jin, the legitimate son of the Sect Master of the Xuantian Sword Sect, was born with an innate Daoist bone. At just three years old, his Daoist bone was stolen, and he was abandoned in the Hundred Thousand Demon Mountains to fend for himself. After awakening the Myriad Demons Emperor Bloodline, he became the young lord of the demon race, commanding eighty-one Demon Kings and the Golden-Eyed Demon Emperor. When his biological parents finally found him, the entire sect favored their adopted son, Xie Yunchuan, while constantly ostracizing and humiliating Xie Jin. Concealing his true strength, Xie Jin secretly investigates and gradually exposes the conspiracy behind the theft of his Daoist bone. To the shock of the entire sect, he summons the myriad demons and embarks on his path of revenge.
