Takeaway rider Chen Mo discovered that there are "blind spots" in the city that don't exist on the map - there are buildings, people, and lights, but the navigation is blank. He started delivering food to the blind area. Those residents were quiet and never showed up, but they could order, pay, and give good reviews. The delivery fee is very high and the positive rating is 100%. He thought he had found a way to make money, until one day he discovered that the community where he lived also began to become... Quiet.
