Xuan Jin, a flower fairy born with the Sacred Green Lotus Spirit Bone, was poisoned and framed by her elder sister, Yu Ling, in her previous life. Accused of murdering her mother and falling into demonic ways, she was imprisoned in the deepest abyss of the Eastern Sea for five hundred years. After discovering the truth on the brink of death, she was reborn through a blood curse, returning to the night before the Ascension Ceremony. Seeing through Yu Ling's successive poison plots, she exposes one conspiracy after another at the ceremony, including poisoned incense, cursed talismans, and a demonic mirror used to frame her. Driven into a corner, Yu Ling allies herself with the demon clan and unleashes a demonic army upon the world. Xuan Jin joins forces with her fiancé, Dongyang Dijun, to fight the invaders, eliminate Yu Ling, and quell the demonic disaster. Only then does Xuan Jin discover that her rebirth was made possible by Dongyang Dijun sacrificing his cultivation. In the end, they marry, protect their loved ones, and find their happy ending.
