In her previous life, Bai Qing was pregnant and imprisoned in the cold courtyard of Prince Jing's palace. The concubine brought poisoned wine with her own hands, and her mother-in-law looked on coldly. When she opened her eyes, she returned to the third day of her wedding, when the tragedy began. In this life, she put away her infatuation and did not fight for favor or beauty. She just wanted to save her life step by step and stay away from this man-eating palace. Unexpectedly, Xiao Jue, the king of Zhaosu who was armed with heavy troops and decisive in killing, suddenly returned to Beijing. He saw through the dirty calculations in Prince Jing's palace at a glance, and directly connected her to his Prince Su's palace in the name of "the nephew's daughter-in-law is weak and needs to be recuperated." From then on, Bai Qing had the strongest backer. The concubine comes to establish rules? The emperor's uncle's words made her ashamed. Is your mother-in-law making things difficult for you and your family? The emperor's uncle stood in front of him: "It's not your turn to teach this king's people." The scumbag ex-husband comes back to ask for reconciliation? The emperor's uncle directly ordered his legs to be broken and thrown out. From the fights in the palace to the disputes over imperial power, Xiao Jue blocked all open and hidden arrows for her, protected her from death in her previous life, and doted on her to the core. And Bai Qing gradually discovered that behind the tragic death in her previous life, there was a shocking conspiracy involving the royal family, which was far deeper than she imagined.
