In the modern city, Lin Changping, a funny and passionate useless takeaway station manager, activates the "Crit Return System" because his delivery station is about to close down and is suppressed by his peers. After completing tasks such as "solving other people's troubles" and "adhering to principles", he can get double rewards (money, connections, skills, etc.), And when in danger, he triggers the "crisis critical strike" rebound damage. He started with small things such as solving the bullying of delivery workers and helping customers find pets. He used double returns to accumulate resources, gradually expanded the delivery station, defeated chain rivals, and invested across fields to become an industry giant. In the process, he met Su Ruoxi, a tour guide with a peerless appearance. From mutual dislike to fighting side by side, he finally reached the peak of his career and a happy family, becoming a winner in life who "protects the people he cares about with critical strikes".
