Chen Du is a night-shift delivery boy in Linjiang City. He relies on an old electric car and subsidies from the platform to make ends meet. During a heavy rainstorm at midnight, he received an order that could not be canceled or transferred, and the address was constantly being changed. The delivery address pointed to the "Midnight Takeout Office" that had long since closed. From that night on, there is an additional midnight line in the ordinary rider APP: an empty hospital bed, an accident intersection, an old building kitchen, an abandoned school rooftop, a neighborhood of the dead, and the main station on the edge of the city. The orders are sometimes given to the dead, sometimes to the living, and sometimes to the obsession that refuses to leave; the temperature of the food, the countdown, the door number, and the delivery notes may all be clues. At first, Chen Du just wanted to keep his negative review rate and longevity, but gradually he discovered that his amnesia, the disappearance of his mother, and the demolition of old alleys ten years ago were related to the first order. The first 50 chapters use unit dramas to promote warm suspense, each order solves an unfinished regret, and at the same time accumulates the main storyline of the firm's rules, life debts, the main office, and the life experiences of colleagues Bai Qing and Chen Du. In Chapter 50, the old rule stage collapsed and Chen Du rebuilt a new office. However, a larger order wall appeared on the other side of the city, and the story entered the next stage of a long-term serialization.
