No one knows that she is engaged in a life-and-death battle with the evil spirits lurking in the shadows of the city every night. She is not a hero, she is just trying to survive. Until an accident, the mysterious blood in her body suddenly awakened, and the ancient phoenix true fire burned her past and ignited her future. She was involved in a conspiracy that spanned a thousand years, and ancient sects, mysterious families, and demons dormant in modern society all appeared one after another. In order to find the mystery of her life experience and to protect the only warmth around her, Lin Weiyang had to abandon her innocence and prove her truth by killing. On this thorny road of cultivation, she will use the blood of her enemies to compose her own Phoenix Song of Eternal Night.
