On a rainy night, red tide broke out and zombies besieged the city. Shen Zhou, a 27-year-old food delivery rider, was trapped in the east of the city. His mobile phone was disconnected and there was no way out. When he was on the verge of death, he was bound to the only System Zero in all mankind - sign-in critical strikes, hidden shops, and hidden professions. He took possession of all the things that others could not ask for. Relying on the takeaway map he had made in three years, he grabbed food, rescued people, and killed half of the city, building a city out of shacks along the way.
