Lin Xiudou is a fat nerd who supports himself and a fat dog by writing pornographic novels. Because of a curse that will lead to death at the age of 25, he was forced by his mother to go on a blind date. Because he failed to make a blind date, he was kicked out by his mother to reflect on himself. He had no choice but to escape to his best friend's house. His superstitious best friend dragged him to the mountain to burn incense to meet the master and open the door to a new world. From then on, he started to live as an evil master on the side, and he never returned on the way to fight monsters.
Because of his unruly and unruly image of being bitten by a dog, insiders gave him the nickname "The No. 1 Sloppy Man Who Suppresses Evil".
