Villagers wearing human skin need to rely on "fairy meat" to maintain their human form, and they have to change their skin every eighteen years to stay alive. Xiaofeng's father said that her mother was killed by hunters because she refused to use spiritual objects, but she clearly remembered her mother's crazy instructions before jumping off the cliff, "Don't change your skin, don't touch the fairy meat." When she was seventeen years old, the village chief asked her to lead three hunters into the holy mountain, saying that she would use the hunters' yang energy to nourish spiritual creatures. Xiaofeng thought it was a plot by the tribe, but when he was leading the way, he saw the hunter pointing his gun at him - they had already figured out the secret of skin-changing, and the muzzle of the gun glowed coldly in the fog.
