On the way to deliver the 9999th takeout order, Lin Xiaofan's battery car was hit by a "Xianyuan Express", and he started a double life. During the day, he was a fast delivery boy, using the 'Lingbo Weibu' to evade the traffic police, and using the 'Air Fetch' to deliver milk tea, with a 100% five-star rating. At night, he was involved in the 'Aura KPI Assessment' and 'Zongmen 996 Fortune Report' in the world of immortality, and had to use the merit earned from delivering food to exchange for cultivation resources. He soon discovered that the world of immortality was facing a crisis of spiritual energy exhaustion, and the flourishing "fireworks energy" and "Internet will power" in the world were actually new energy sources. When the traditional cultivating sect tried to block the human world to monopolize resources, Lin Xiaofan united with fellow cultivators who were hiding in the market - the sword fairy who drove Didi, the fu cultivator who did housekeeping, and the demon cultivator who engaged in live broadcasting - to form the "Service Alliance of All Realms", using the professional qualities of delivery workers (on time, politeness, problem solving) to launch a dimensionality reduction attack on the ancient world of immortality. The story uses a relaxed and humorous tone to tell how the protagonist uses an electric car to measure the three realms and uses an incubator to deliver warmth, and finally breaks prejudices and establishes a "new civilization of immortality" that connects the two realms of immortality and mortals and promotes common development. The climax occurred in his ultimate mission to prevent the giants of the world of immortality from launching the "Jedi Tiantong Formation" to isolate the world. He must deliver a "family portrait milk tea" to the center of the formation within 30 minutes. This delivery will determine the future of the two worlds.
