I Raise My Dad by Picking Up Scrap

Li Jiujiu was a rich third-generation heir who coasted through life, until one day she traveled back more than twenty years and became a little fool who slept in a junkyard and survived by collecting scrap. Li Jiujiu: "I wasn't worried at all. My dad was rich, so I wouldn't go hungry." According to her dad, the Li family had once been the richest family in Lancheng. As the only child, he had grown up surrounded by wealth, a freewheeling man as breezy as the wind. After going hungry for days, Li Jiujiu finally found Li Yan, only to discover that the boy who had tried to snatch scrap from her a couple of days ago was her legendary breezy-as-the-wind dad. Li Jiujiu: "...Dad, how did you turn out like this?" It was bad enough that he'd lied about being rich, but he had even fought her over bottles. "Don't think calling me Dad means this bottle is yours!" Li Yan clutched the plastic bottle in his hand, eyeing her warily. Li Jiujiu: "..." Then Li Jiujiu took a month to accept the truth: her dad wasn't a rich second-generation heir at all. He came from generations of poverty. "Don't be scared, Dad. I'll collect scrap and support you!" Li Jiujiu patted her little chest and promised solemnly. Li Yan: "..." The little fool might be daft, but she was pretty loyal. Theme: Return to the past, work hard at life, and study diligently.
