A literary fantasy novel about Zhang Yaowei, a disciplined cultivator, and Jin Zhan'er, a fox spirit whose forced shared-fate bond becomes the beginning of a journey through ghosts, demons, local gods, underworld law, old hatred, forbidden arts, resurrection, and a final battle against an ancient rage. Blending xianxia atmosphere, supernatural romance, ghost-story mystery, and mythic conflict, the story follows two unlikely companions as they choose mercy over inherited cruelty and seek a freer life beyond the ordinary bargains of the human world.
