Single father Wu Yan and his five-year-old daughter Wu Xiaoman live in an old bungalow on the outskirts of the city. They make a living by doing odd jobs and live in poverty. After an accidental electric shock, he activated the "Skill Chaos System", which randomly refreshes a life skill at midnight every day for only 24 hours. These skills may seem "crooked" - children's nutritional meal preparation, pet first aid, space storage, crisis prediction, public opinion tracing, etc. - But they can always help him solve problems in life at critical moments: improving his daughter's nutrition, protecting his daughter's mental health, countering the frame-up of malicious competitors, and in the contest with the insidious neighbor Zhou Chengming, step by step to protect his family and expand his "Yanjia home service" business.
