Shadowless Reincarnation

At three o'clock in the morning, I bumped into a man without a shadow in the corridor. He asked me if I saw his shadow. I lowered my head and found that my shadow was being eaten by the black mist. On the thirteenth day of the seventh month, the shadow debt is the life, the corridor is the cage, and the shadow is the sacrifice. I thought that running away would be the only way out, but I didn't know that the faceless driver was already reflected in the taxi's rearview mirror. When the shadow disappears, people become deceitful. And in this shadowless reincarnation, there is never a way out. Either become the new building guard, or be entangled in the black mist forever, repeating the same death in the endless midnight.
