Three years ago, I broke a bronze mirror in an ancient temple, but I didn't know that this smash released the evil energy of the entire mirror world. From that day on, a dark door suddenly appeared in my rental house. The door handle was tied with a dark red knot, and a trace of black mist seeped from the crack in the door. I thought I was hallucinating because I was too tired from overtime, until that invisible hand suddenly pulled me into the door.
