In her past life, as the Crown Princess, Su Tang suppressed the transmigrator Shen Lingxi, resulting in the tragic end where the entire Su family was slaughtered and she and her enemy perished together. Reborn, she hides her brilliance and feigns obedience, vowing to protect her loved ones and exact revenge. Knowing secrets, the deep-palace Empress Xiao Dai is also a transmigrator, relying on hunting down peers and seizing destiny to consolidate her power. The reborn Shen Lingxi fancies herself a game player, treating everyone like NPCs and acting with unbridled arrogance to court death. Step by step, Su Tang plays a calculated game, leveraging Xiao Dai to eliminate her arch-enemy, secretly subverting the system to dismantle the Empress's power, and turning the tables to manipulate the ambitious Crown Prince Wei Yan. Cutting off her tragic destiny, she stands firm with the backing of the Su family's military power.
