Yunyao, a girl with the gift of animal language, rescued a seriously injured nine-tailed fox in the secret realm of Kunlun, but was accidentally involved in the prophecy of "The Worship of All Beasts". It is rumored that the one who can command the beasts can control the power of the ancient beast god, and both the immortal sect and the demon clan want to fight for it. The nine-tailed fox's true identity is Yeli, the prince of the demon clan. He conceals his identity and travels with Yunyao. The two gradually fall in love while evading pursuit, but they discover that behind the prophecy there is someone who wants to use the power of the beast god to overturn the balance of immortals and demons.
