The Qingqiu Fairy Mountain recorded in the "Book of Mountains and Seas" is hidden deep in the sea of clouds. The beautiful jade flows in the south of the mountain, the green eagles in the north are emerald, the gurgling water nourishes the red cockroaches with human faces, the sound of divine birds irrigating and singing awakens the world, and the nine-tailed fox has practiced here for thousands of years.
However, a sudden change caused by ancient resentment shattered the Qingqiu barrier, and monsters escaped into the world. The auspicious name of the Nine-tailed Fox Clan was stained, and ferocious monsters spawned by the power of chaos occupied the mountains and forests, disturbing the peace between the human and fox worlds. Ling Xi, a young fox cultivator, has the mission of guarding Qingqiu, and embarks on the road to catch monsters with a magic weapon made by Guan Guan Feather. She must not only fight against the out-of-control demon spirits of her own race, and solve the millennium misunderstanding that "nine tails are a disaster", but also join forces with Xuan Chen, a righteous Taoist priest in the world, to trace the source of resentment.
Along the way, they met the innocent souls weeping blood, the good demons guarding one side, and they also saw the greed in the human heart that is stronger than the demons. In the battle of wits by the Yingshui River, the ancient magic circle in the secret realm of Qingqiu, and the mystery of demon disasters in the human town, the two gradually uncovered the dusty truth of Qingqiu's transformation from an auspicious holy land to the "Land of Demon Ancestors". They also discovered that behind this turmoil, there was a shocking conspiracy about the symbiosis of humans and foxes. When Lingxi's nine-tailed power awakens, Xuanchen faces the choice of a human-monster. Can they use courage and wisdom to resolve the grudges between the two worlds and allow Qingqiu to return to the mist-shrouded peaceful fairyland?
This is an adventure intertwined with myths and legends and chivalry. It not only has the strangeness and agility of the rare and exotic animals in "The Classic of Mountains and Seas", but also the passion and warmth of the confrontation between good and evil, and the choice of friendship.
