Mountain village youth Zhou Yuan, inheriting his grandfather's legacy, exchanges his life's blood for the chance to deduce destiny. He accidentally meets An Ruoxi, a fairy of the Spirit Sect who is afflicted with a bizarre poison, and after forming a bond with her, steps into the Myriad Phases Spirit Sect. Possessing a second-grade lightning spirit root, he is looked down upon by the sect, but Zhou Yuan continuously grows stronger through life-blood divination and miraculous treasures. While dodging schemes, he investigates the mastermind behind poisoning the fairy, maneuvering among various figures, rising in counterattack amidst the perilous Spirit Sect, and tenaciously pursuing his own celestial and romantic destiny.
