The twilight is like ink, Youlan was born in troubled times, and is the guardian of the soul of an ancient village. His body is half blood and half soul. He walks around the world during the day and ferries the souls of the dead at night. At that time, the living and ghosts coexisted, the barriers between Yin and Yang were gradually lost, wronged souls demanded their lives, gods fell silent, and the people were panicked. Youlan originally wanted to protect the peace of the village, but on a ghost-moon night, she caught a glimpse of the ghost of her dead mother, and realized that there was a broken destiny behind her life experience: if she wanted to save her mother, she would have to separate the worlds of humans and ghosts forever, cutting off the communication between yin and yang. However, as You Lan sees, the suffering of the dead is no less than that of the living, and the obsession of the living cannot leave behind their past lives. On the edge of reincarnation, she can only use her half-soul body to travel between life and death, searching for the lost destiny talisman and awakening the sleeping gods. Between power, family affection and compassion, how will Youlan choose? The legendary picture of the intersection of yin and yang slowly unfolds, and a strange story about destination and letting go, redemption and betrayal quietly begins.
