A wisp of lingering thought from Guixu reveals memories sealed away for ten thousand years.
Mu Xi, a Heart-Moon Fox, makes a vow to the Buddha to save the man she loves, Mu Nian. She plunges into the sea of suffering in the mortal realm, enduring the Eight Sufferings in life after life.
In her first life, she is a spirit fox, innocent and not yet wise, while he is a monk in quiet cultivation at an ancient temple. They keep each other company in the wilderness, sharing gentle, everyday warmth, but cannot escape separation and death. When the monk passes into nirvana, she follows him in death.
When they meet again, he has become the exalted Snow God, born without a heart and stripped of all memories of the past. Yet Mu Xi's innate Bodhi heart is the only key that can awaken his seven emotions.
Through countless cycles of reincarnation, she has been a lonely immortal maiden and descended into the dusty dreams of the underworld. In every life, she meets him again, yet every time she is doomed to yearn for what she cannot have.
It turns out that all his love and hatred began with her. She has wandered through a thousand years of reincarnation, waiting for him to understand a profound love.
As the causes and consequences of the past are gradually revealed, obsession intertwines with great love. At last, within the great dream of the mortal world, Mu Xi saves him, and herself as well.
Theme: Rooted in the idea that the "Eight Sufferings are part of life" in the mortal world, this story explores how love should not be a one-sided sacrifice that serves only to make the giver feel virtuous. True bonds come from seeing each other and saving each other. Memory is not the same as love, and forgetting does not mean a bond has ended. Obsession can save, and hearts can awaken. Love does not mean erasing yourself: it means holding on to who you are as you reach for someone else. The story also examines the shackles of fate and the power of personal choice. Humans, gods, and demons are all bound by karma, but the awakening of the soul will always remain in one's own hands.
