Chen Yan, an ordinary and capable office worker, lives alone with his five-year-old daughter, Xiao Nuomi, after his divorce. One day, a program called "Skill Intrusion System" was suddenly implanted into his mobile phone, randomly inserting a new skill every day - from cooking proficiency, child psychology to fighting skills, first aid knowledge, and even repairing home appliances. At first, Chen Yan just wanted to use these skills to take good care of his daughter, but he didn't expect that the skills he used were getting more and more outrageous. Neighbor Wang Xudong is a paranoid who is enthusiastic on the surface and twisted on the inside. He starts to do evil in secret because he is jealous of Chen Yan's daughter's love and the recognition of his neighbors. With his capable handling style and constant intrusion skills, Chen Yan healed his daughter's separation anxiety while uncovering Wang Xudong's dark past. In the daily life and technical adventures of being a dad, he learned how to be a real father.
