Supernatural Recovery: I Am the Only Ghost

The underworld ghost Ye Ming finally got the chance to retire after working hard for more than a thousand years. He was reincarnated into a blue star in the end of the Dharma era. After working, he entered university and became a physical education teacher. There are no ghosts and ghosts here, and I thought I could enjoy my retirement life comfortably. However, who knew that the supernatural would revive, and all kinds of evil ghosts and ghosts were everywhere, so Ye Ming had no choice but to return to his old career and become a ghost servant again. It's just that unlike before, there is only one ghost named Ye Ming in this world.
