Lu Chengze, on the surface, appears to be a decathlon genius who is proficient in eight languages, can defuse bombs with his bare hands, and can cook a Manchu-Han banquet, but in fact he is a living idiot who can't even cook instant noodles and will get lost when he goes out. With the magical golden finger of "Mom's Remote Control", he wandered around the city and became a private detective. However, when he took over a seemingly simple disappearance case, he was accidentally involved in an elaborate conspiracy. The mastermind behind the case turned out to be a mama's boy villain who was extremely dependent on his mother and had no independent opinions. As the investigation deepened, Lu Chengze discovered that his most trusted assistants and even clients were inextricably linked to the villain. Trust gradually collapsed, and Lu Chengze had to get rid of his absolute dependence on "mom's orders" in the process of solving the case full of laughter, and truly grew into an independent detective.
