Wowo, a young nine-tailed fox from Qingqiu, takes the jade pendant her mother left behind to the Demon Abyss to find her father. The Demon Lord is at a loss as the soft, adorable little girl keeps calling him Daddy. Wowo thinks the Demon Realm is her father's bandit stronghold and the Demon Lord is its mighty bandit chief. She can eat ten bowls of rice in one sitting without getting a belly, and even drag the heavy greatsword from the storehouse. Everyone in the Demon Realm is exasperated and amused by her. Her father, a man with a sharp tongue but a soft heart, is gradually melted by her warmth, and from then on he has a sweet little darling who fills his heart with joy.
