Shen Qingci, the legitimate daughter of the Prince of Zhenguo, was a childhood sweetheart with Prince Jing Xiao Jue. She happily married into the prince's palace, but she became Bai Yueguang and Su Lianyue's stand-in. In order to support Su Lianyue, Xiao Jue teamed up with the Su family to frame the Shen family, causing everyone in the Shen family to be executed. Shen Qingci managed to escape, but his appearance was damaged and he was seriously injured.
Three years later, Shen Qingci changed his name to Su Ci, a female doctor, and returned from hibernation with her superb medical skills. Her only obsession was revenge. She sneaked into Prince Jing's palace step by step, taking advantage of Xiao Jue's interest and doubts in her, secretly collecting evidence, contacting the old department, and dealing with Xiao Jue and Su Lianyue.
On the way to revenge, Dali Temple minister Xie Yunchen silently protected and helped Xiao Jue, and while getting along with each other, Xiao Jue gradually discovered the many similarities between Su Ci and Shen Qingci. Guilt and suspicion were intertwined, and he began to frantically explore the truth. When the truth was revealed, Xiao Jue was filled with regret and embarked on the road to chase his wife to the crematorium. He did not hesitate to give up his power to atone for his sins, but in the end he could not save Shen Qingci.
In the end, Shen Qingci exposed all his crimes and made his enemies pay the price, and the Shen family was avenged. She put aside her hatred and took care of herself, while Xiao Jue died alone in endless regret, and it was difficult to reconcile the broken mirror.
