**Chu Ma (出马) Spirit Mediumship**: This is a folk tradition, especially alive in Northeast China, where a human becomes the "mount" or vehicle for a powerful spirit—often a fox, weasel, snake, or other animal immortal. The process is violent and involuntary; the chosen person typically suffers a life-threatening illness or madness that only resolves when they "mount the horse" and accept the spirit. Bai Lingmiao's confession that she became a *chu ma* disciple *without* Li Huowang's knowledge is a huge character reveal—she has taken on a body-changing, reality-bending burden to save him, and it makes her far more than the "helpless girl" she appeared to be.
