I Was Touched by Wong Tai Sin

My name is Chu He, and I am an ordinary office worker. Until that day, I was "touched" by a weasel in the parking lot. Not only did it poop on the front of my car, it also ran into my brain and refused to leave! From then on, my world was completely turned upside down. "Boy, do you want to learn? I'll teach you! First get a roast chicken as tuition!" Under the pressure of this poisonous old monster, I was forced to start a second career of catching ghosts and subduing demons in the city. But I always feel something is wrong. This old guy... Seems to be hiding something scary?
