Shen Zhaoning had died once. In her previous life, her half-sister and her fiancé, the Crown Prince, joined forces to throw her down a dry well, where she starved to death. When she opened her eyes again, she had returned to three years earlier. This time, she decided she wouldn't be a good person. She sought out her greatest enemy from her previous life, Helan Yan, the Regent of an enemy kingdom who killed without blinking, intending to exploit his secret and make him her weapon. What she didn't know was that, in his previous life, the last word Helan Yan uttered before he died was her name. In this life, before she could even try to turn him against his own side, he had already delivered himself to her.
