In her past life, she died for him to seal away the demons, her soul scattered into nothing.
In this life, she is an orphan he took in, with the unbroken "Spirit-Suppressing Pact" from a century ago branded into her soul, and half his soul and a blood jade pendant hanging over her chest.
Liu Hongfeng, the last inheritor of Tianshu Peak, sealed half his soul in the jade and kept watch alone for a hundred years, waiting for a soul that might never return.
Xu Xiaowei has no idea why she was reborn. She only knows that her aloof master would give his life to protect her, and that the evil spirits of this world see her as a "key."
As the "Netherworld Path" reappears, the seal weakens, and the ancient pact awakens...
The master and his disciple set out from Beiman Mountain, encountering reanimated corpses, haunted towns, demonic Taoists, the misty rains of Jiangnan, and secrets buried for a century,
all to discover why she died back then, and whether this "Red Pact" binding them is a shackle or a homecoming.
