The young girl Su Qingyuan has been cultivating in the Qingyun Sect since childhood, and has been despised by her peers due to her defective spiritual roots. No one knows that she has forged a millennial spiritual pact with a spirit cat named Bainuo, and their destinies are closely intertwined. Inside the valley altar sealed for many years, the old seal quietly loosened, and the sect's past hidden for many years gradually surfaced. The master of the Qingyun Sect, worried about the resurgence of old secrets, stepped in to block the ritual. Su Qingyuan and the spirit cat joined hands, step by step uncovering the hidden past of the sect, adhering to righteousness in their hearts, and embarking on their own path of immortal cultivation.
