Maomao falls off a cliff with a hiking group and ends up in the sea survival novel "Survival in Raging Seas: Drifting in Desperate Drifts" that she just read. She floated in the Pacific Ocean with only an orange rubber boat and a few supplies. As an ordinary office worker with no experience, she relied on the fragmentary knowledge in the book to find reefs, fresh water, and catch seafood. She tried her best to survive in the desperate situation of the blue sea amidst storms and unknown crises.
