Lin Mo time-traveled back to 1975, where his father was biased, his stepmother was harsh, and his younger brother plotted against him at every turn. Fortunately, he awakened the One-Yuan Flash Sale System, which could exchange for massive supplies every week. Unable to bear the exploitation at home, he resolutely split the family, sold his job to go to the countryside, and completely cut ties with his family of origin.
