I am not a human being, just a wild ghost, floating in the world just to see what the world is like. When I floated to a small mountain, I stayed there for five years, only because I accidentally broke into the small mountain god who used to live here at the entrance of the mountain. However, the small mountain god had ascended, and I was left in the cave. I was left in a small space here. I let the small space recognize me as its master and at the same time, I looked at the empty space and nothing inside.
