The snow in Kunlun is burning, the nine heavens are cold, and the River of Forgetfulness is crossing the distance. The sight of Zhiyuan, the ten-tailed celestial fox, and A Zhuo, a mortal girl, revealed a fateful entanglement spanning three lives. In the first life, she lost his soul to protect him, and he was frozen in Kunlun for thousands of years and drank hatred; in the second life, she awakened him from Nirvana and turned into a useless immortal soul. The immortals and demons colluded, and the trials shocked the soul, making love and hate difficult to distinguish; in the third life, the two of them faded away from their identities as immortals and demons, and lived in seclusion in Wuzhen to spend time together. However, they were involved in catastrophe again because of a solitary crystal that condensed the power of the balance of the three realms. The gentle years of Jiangnan Embroidery Workshop are no match for the madness of the covetousness of the three clans; the obsession and madness of the second female Lin Yue (Ling Yue's reincarnation) has added bloody cracks to this relationship. When the solitary crystal is doomed and the common people are in danger, Lingxi can only use his soul as a guide for the broken crystal to die as a martyr, exchanging three lives of love for the peace of the three realms. Zhiyuan's obsessive persistence, Cang Jue's silence, and Lin Yue's atonement have all become the most heart-wrenching footnotes in this fateful tragedy.
