Su Wan, the youngest editor in the Heavenly Fate Book Department, has been writing destinies for mortals for three hundred years, and there has never been any trouble. Until she opened the life book of her younger sister Su Wei - the little girl who had called her "Sister" for ten years in the mortal world was about to face an irreversible ending. But there is a rule in the Book of Fate: Editors are not allowed to interfere with the fate of people who are related to them. Violators will have their immortal status cut off and their path to immortality cut off. On one side is the cold sky, on the other is the call of blood relatives. Su Wan picked up the pen and wrote words that went against the destiny for the first time. She wants to use her own fairyland to exchange for the eternal peace of her sister. This is a story about family love, resistance and redemption - fate may be unfair, but love can rewrite everything.
