Su Wanli, the eldest daughter of the Prime Minister's residence, was drowned in a lotus pond by her younger half-sister Lin Ruorou. Reborn one day, she binds with a Destiny Defying System. She sees at a glance the Prince Regent Xiao Jinyuan's fated death: only three months of life remaining. Xiao Jinyuan, cursed with both the God-Slaying Gu and the Heart-Eroding Curse, has hidden in the shadows for twenty years building a secret network, only to be firmly held onto by her on the brink of life and death. From inner residence struggles in the Prime Minister's Manor to political maneuvering in the imperial court, from the mysterious western market to the cold northern waters, she seeks medicine and breaks curses with courage and insight, while he protects her with all his power. Brothers turn against each other, curse secrets come to light, the shadow network is rooted out—she tears apart her doomed fate, and he survives his death deadline. At last their destiny is fulfilled, and they spend a lifetime of peace together.
