Director of the Security Bureau: "Classmate Li, the country needs you." Li Chang: "Sorry, I don't know how to catch monsters." The world's richest man: "Mr. Li, please help me." Li Chang: "Sorry, I'm not interested in catching ghosts." Top hacker: "Li Chang, the world needs you." Li Chang silently unplugged the power: "Aliens are invading, you should call the National Security Agency." This novel and its characters are purely fictitious.
