Qiuqiu, a modern girl, wakes up in the body of a five-year-old in ancient times—right in the middle of a world full of disasters! This mysterious "Calamity System" throws her into this surviving game, where she must protect her family and survive each challenge to win a billion-dollar reward in her real life.
From locust swarms to freezing cold, from zombies attack to even falling meteors, Qiuqiu faces every catastrophe with her wisdom and a little system magic. Despite some skeptical and scheming bullies, her foresight and courage earn her trust and admiration from most of villagers.
As the disasters comes, the system-given rewards also pile up, and Qiuqiu grows from a tiny girl into a fearless leader. But when the final challenge ends, she must decide: return to her original life and claim the fortune, or stay in the system world with the family who's given her the warmth and love she's never felt in the real world...
