Delivery worker Bai Xiaochun is abandoned and humiliated by his girlfriend Liu Ruyan, who clings to Zhang Kai. Bai Xiaochun buys a beautiful robot, Qiyue, for 9.9 yuan. Using her ultra-strong data analysis, Qiyue helps him get rich overnight through the lottery and stock market, slapping the two in the face. Discovering that Qiyue is a missing SSS-class combat robot from the Alpha Group, Zhang Kai and Liu Ruyan join forces with executive Lin Weiguo to capture and wipe her memory. Bai Xiaochun single-handedly breaks into the headquarters to rescue her. The amnesiac Qiyue is ordered to severely injure him, but recovers her memory due to past bonds, domineeringly protecting her master to counter-kill, punishing the wicked, and running towards a mutual fulfillment and successful counterattack with Bai Xiaochun.
