In the mist beside the Forgotten River, a soul resonance that transcends life, death and prejudice quietly grows. When the fingertips of the ghost girl, as pure as the morning sun, pass over the water of Wangchuan River, what is reflected in the ripples is not only the memory of thousands of years of reincarnation, but also the fateful encounter with the man carrying the secret of Ginkgo Villa. Their story is a life piece about understanding, tolerance and awakening. In the intertwining of conspiracy and redemption, the brightest light of human nature shines out.
The ghost girl born in the Wangchuan River is surrounded by an ethereal aura that is not stained by dust. She uses Meng Po Tang as a guide and witnesses the joys and sorrows of countless souls, but she always maintains the clear eyes of a child. Until that moonlit night, Cheng Muyang of Ginkgo Villa came like a banished immortal. His sword blade split open the monks from the aristocratic family who surrounded and suppressed the ghost girl, and also split her lonely world isolated from the world. When Cheng Muyang put the blood-stained robe on her thin shoulders, the words "I will take you home" were like the spring breeze turning into snow, melting her thousand-year-old defense. The two supported each other on the way to escape. When the ghost girl used the water of the Wangchuan River to heal his wounds, what flashed in his eyes was not fear but pity: "The purest soul in this world should not be judged by the so-called righteous way."
As the truth emerges, the secret of the ghost girl's red blood involves the darkest conspiracy in the world of immortality. On the surface, the eight aristocratic families pretend to be doing justice for heaven, but in fact they covet her bloodline to refine immortality elixirs. Cheng Muyang, as a child of an aristocratic family, chose to stand on the balance of justice and love, and used the "Pure World Sword Art" guarded by Ginkgo Villa for generations to fight against the family's corruption.
