A sudden global natural disaster reduced cities to ruins. When six civilians with different personalities encountered monsters and chaos, they accidentally formed a group and struggled for survival. The doomsday environment is full of danger and absurdity. The team members use funny complaints and bizarre strategies to experience material snatching, monster siege, and open and secret fights among survivors. Arguments that break out in a crisis lead to disintegration, but also to tender healing and self-salvation; and everyone is growing and changing, constantly breaking boundaries with optimism and courage. In the end, the six people faced the ultimate crisis of the apocalypse and found new hope in despair. The plot of the whole book is ups and downs and compact, not only losing the tense atmosphere of the apocalypse, but also full of humor and human touch.
