Ethan Reed, a poverty-stricken worker who can barely afford rent, accidentally binds a legal Cashback Rebate System in his shabby rental unit: all daily consumption gets double returns, and public welfare expenditures get triple rebates. Grateful for the system, he pays off the debts of Lila Lee, whom he has had a crush on for many years. Supported by the system, he repeatedly breaks others' prejudices and calmly fights back against the harassment from wealthy brats. He then grows step by step, purchasing luxury cars and real estate, acquiring wineries to revitalize industries, and recruiting industry elites to build a team. Facing malicious suppression and unfair competition from business rivals, Ethan adheres to compliance principles, confronts capital monopolies head-on, and dismantles his opponents' plots. He finally achieves a successful comeback.
