I am a lonely, uh, ghost, a happy ghost.
I have been dead for seven hundred and thirty-eight years. During these seven hundred and thirty-eight years, my greatest happiness was to sit in a beautiful man's house and collect some oil on the way. Of course, they couldn't see me, but who told me that when I touch someone's face, my body will go directly through it! Until one day, something mixed with loess, sand, and unknown black objects can blow me up into the air. Time travel is good, but why can't I stay in each world for more than three months? No!
