Middle-aged man Gu Minghui is treated as a free ATM by his wife and son, handing over his entire monthly salary of 50,000 for household expenses, yet even getting berated by his son for buying a 1,000-yuan tea set. Feeling thoroughly cold-hearted, he suffers a sudden myocardial infarction and falls silent, while his closest kin refuse to even show up to sign for the surgery. In utter despair, Gu Minghui resolves not to repeat past mistakes, coincidentally binding the God-Level Autonomous Cash-Back System, where spending on himself yields ten times cash refunds. Smilingly bidding farewell to the medical staff and facing the warm sun, he strides toward the commercial street to embrace his refreshing life!
