Lingyu, a nine-tailed fox who was once the most powerful divine beast in a fantasy world, loses all its magical powers for some reason and becomes an adorable little fox loved by everyone. Adopted by an ordinary human girl named Xiaotao, it hopes to lie low and enjoy a carefree life, but keeps getting dragged into hilarious incidents, from competing with a little stray dog for affection to outsmarting adorably foolish villains. Amidst warmhearted and laugh-out-loud everyday adventures, Lingyu gradually discovers the true meaning of an ordinary life—until a crisis arrives and it must finally make a choice.
