The apocalypse descends, the infected become madmen, and order collapses overnight. Qing Shui leads companions to survive with difficulty between the zombie tide and human hearts; some get lost, some sacrifice, but there are always those who choose not to abandon, not to give up. A bowl of instant noodles shared, a wisp of smoke raised for companions, a sentence that the country will not abandon any single person, let the desperate long night reveal a faint light. This is a story about ordinary people guarding each other and facing death to live under the apocalypse.
