Shen Zhiyi was exploited by her husband, General Gu Chengyuan, and single-handedly bore the burdens of the General's Manor after marriage. Reincarnated back to the past, she presents beehive coal to the Emperor in exchange for an imperial divorce decree, then allies with Prince Qin to oppose both Gu Chengyuan and Prince Jing—systematically dismantling the General's Manor's power, publicly exposing and humiliating the concubine Liu Ruyan, securing her divorce, and ultimately prompting Prince Qin to petition the Emperor for her hand in marriage.
