Exorcise Ghosts from Fat House

My name is Guo Laosan, I am 21 years old and I am a ghost exorcist. Because I come from a family of ghost exorcists, I have learned some knowledge related to ghosts and monsters from my father while going to school since I was a child. Now I am a college graduate. I have found a job as a programmer in a place far away from home. I rent a 20-square-meter house. I send half of my salary home every month, and the remaining half is spent on food, drink, and fun. I always thought that the ghost exorcism industry had become an antique, but I didn't expect that since I came to the big city, weird things have happened one after another.
