A wisp of obsession in the Guixu Realm awakens memories of the past. Amid shattered fragments of time and space, Mu Xi glimpses the promise she made to Buddha in exchange for her beloved's chance at survival: to enter the Saha world in every life and endure the eight tribulations of birth, old age, sickness, death, separation from loved ones, meeting those one hates, and being unable to obtain what one desires.
This cycle of reincarnation spanning ten thousand years is both salvation and a prison.
When they first meet, she is a moon fox without awakened intelligence, and he is a monk cultivating in an ancient temple. Guided by Buddhist teachings, they accompany each other through one lifetime. After the monk passes away, she dies for love. When they meet again, he has become the Snow God. By then, both have forgotten their past lives, and the Snow God, born without a heart, is incapable of love. The bodhi heart within Mu Xi is the only key that can awaken the threads of affection in him.
In the lives that follow, she is sometimes an immortal maiden guarding her solitude, sometimes someone longed for in the Underworld. In every life, she meets that familiar figure again, only to pass him by under the destiny of being unable to obtain what she desires. The one she has been obsessed with for ten thousand years changes from a monk cultivating the Way into the heartless Snow God. Through their cycles of reincarnation, it is the bodhi heart within her that allows him to develop affection and the seven emotions and six desires.
The causes and effects of their past and present lives keep turning on their heads, and the love and obsessions buried deep within them gradually come to light. In the end, the Snow God learns to love through the bodhi heart, while Mu Xi finds her true self and gains understanding. In the Saha world, she sees through love and hate, saving both herself and others.
As their shattered memories are pieced together, every bond proves to be a clue, and every reunion conceals a cause and effect. At last, she and her beloved see through the truth of suffering in the Saha world. They find their true selves and save one another, breaking the shackles of reincarnation with love and wisdom and achieving a double salvation, for themselves and all living beings.
In the Saha world, all must endure suffering, and all beings are caught in love.
Core Theme: With the Saha world, a place where one must endure imperfection, as its backdrop, the protagonists' entanglements and tribulations across many lifetimes explore the meaning of love and salvation. Whether it is a god saving mortals or a human saving a god through deep devotion, both ultimately complete their spiritual cultivation amid imperfection and pain, finding a glimmer of warmth within themselves in their darkest hour and attaining the ultimate understanding of life and love.
