In 2026, lazy office worker Yu Xiaxia time-traveled to 1980, becoming an 18-year-old orphan whose grandmother had just passed away. Her only companion was Debao, an offline, standalone pitfall of an AI that didn't understand the rules of the 1980s. Every bad idea it came up with caused her to crash and make a fool of herself. From working odd jobs in the city to failing three business startups, relying on modern common sense and grassroots exploration, she eventually opened a shop and a processing factory, dodging pits all the way to make a comeback as a free and wealthy young woman in a small eighties town.
