On the Gui Chu Continent, in the Cangbei Secret Realm, five-year-old Ye Tingnan risks her life to bring back a simple-minded Ghost King from Mount Xuanfeng. Later, she falls into a five-year sleep after taking too many Return-Origin Pills, sleeping away a quarter of the twenty years of yang lifespan allotted to her across nine lives!
To save her own skin, she has no choice but to grit her teeth and leave Cangbei with San Pang'er, her childhood companion, and her young uncle, following the skinny, scraggly old Taoist Ziyang. From then on, they embark on a perilous journey to reshape the laws of heaven and earth and create a Fifth Realm!
