Rosie Harris, the cub of the ancient beast Taotie, escaped to the human world. Caught dining and dashing, she was adopted by Commander Mason Harris. Using her ability to devour misfortune, Rosie repeatedly saved the Harris family, earning deep affection from Mason and his three sons. Dora Harris, a transmigrated character dissatisfied with the altered plot, allied with Mason's sworn enemy Peter North to scheme against Rosie, but all attempts failed. Eventually, Rosie found Mason's long-lost third son, awakened his comatose wife Thea Innes, repelled Heaven’s recall, and lived happily with the Harris family as an ordinary person.
