Ling Xuan, the number one Immortal Venerable in the cultivation world, is aloof and otherworldly. His cultivation and looks both rank among the highest in the Three Realms, making him the unattainable ideal admired by countless cultivators. One day, at his master's behest, he takes in a gifted direct disciple, Shen Qingci. His little disciple is obedient, adorable, and innocent, and those clear, deer-like eyes make Ling Xuan's immortal heart soften for a rare moment.
However, Ling Xuan gradually realizes that something is off about this “good disciple.” He sneaks off at night to drink Ling Xuan's prized immortal wine, and once drunk, turns into a fluffy nine-tailed fox who clings to his leg and won't let go. He pretends his chest hurts so he can snuggle close and ask his “Master to blow on it.” He even gazes up at him with innocent eyes and asks things like, “Master, what is dual cultivation?”
Ling Xuan thinks the child is simply too young to know better. Little does he realize that this fox spirit, who's lived for over a thousand years, is carefully carrying out a plan to “make the aloof Master his own.” From stunning everyone at the sect's junior tournament to risking his life to protect Ling Xuan during an expedition into a secret realm, Shen Qingci uses his “obedient” facade and formidable strength to elegantly face-slap everyone who looks down on him, while slowly chipping away at the ice around Ling Xuan's heart.
It isn't until a conspiracy spanning the Three Realms pushes Ling Xuan to the brink that Shen Qingci reveals his true form as a nine-tailed fox, striking fear into all around him with the might of a Demon King. Only then does Ling Xuan realize that the supposedly obedient little bunny he raised is actually a cunning, scheming big bad wolf (fox) who wants nothing more than to carry him off to its den. And Ling Xuan is already more than willing to go.
