Chan Chan's life as a fox is anything but ordinary.

Her friends take only 300 years to master the art of transformation into human form—she requires 500.
Her companions enjoy the pleasures of human luxuries, with some even becoming imperial consorts—she's stuck stealing chickens just to get by.
While her friends feast on their stolen bounty, Chan Chan has the misfortune of encountering the Headmaster of Mount Shu.

Back then, he was just a humble Daoist. Now, he's an immortal celestial being.

To make matters worse, this immortal master decides to take Chan Chan—a mischievous little fox—as his disciple, dragging her along on a journey to slay demons and exorcise spirits. But here's the twist: Chan Chan herself is a demon.

Armed with newfound exorcist skills and caught in a paradoxical life, Chan Chan must navigate her role as a monster in a world where she's supposed to hunt her own kind. And her celestial master? His serene immortal demeanor hides more secrets than she could ever imagine.

In a tale of magical mischief, adventure, and humor, the question remains: can a fox demon truly embrace the life of a demon-slaying disciple? Or will her nature ultimately catch up with her?
