Lin Xiaofan, the god of war who once frightened the dark world around the world, buried his medal in the soil after completing his last mission, and used a false identity to become an ordinary delivery boy in Jiangcheng. He is obsessed with five-star reviews, order-grabbing skills and warm interactions with customers. He believes that delivering a hot Malatang on time is more fulfilling than saving the world. However, the tree wants to be still but the wind does not stop. First, he encountered a bank robbery while delivering food. He had to use "superhuman speed" to quietly solve the robbers but claimed that he was "just running fast"; then, an order for milk tea to be delivered to an abandoned factory allowed him to break into the secret base of the former organization "Tianqiong" in Jiangcheng. The new commander is Qin Wushuang, his former junior, who is planning to use dangerous technology to "reconstruct" the social order. Lin Xiaofan wanted to continue pretending to be stupid, but when he saw that familiar neighbors, friendly merchants, and even his colleague Aqiang who always competed for orders with him might be involved in danger, he realized: some responsibilities cannot be delivered. He must solve the global crisis in the most unobtrusive way - while delivering takeaways. The story unfolds in a relaxed and humorous daily life: he uses tactical thinking to optimize food delivery routes, uses interrogation skills to deal with malicious negative reviewers, and uses investigative skills to help the old lady find her cat. At the same time, Qin Wushuang's plan gradually escalated, from local experiment to global threat. Lin Xiaofan had to join forces with the webmaster Chen Jianguo, the milk tea girl Su Xiaoxiao, and even the weird old Li Tou who always ordered takeout during the meal delivery break to form an "irregular defense alliance" based at the takeout station.
