Yan Jiuge, once a renowned doctor in the twenty-first century, transmigrates by accident into the body of the abandoned Princess Consort of Prince Zhao, left to die at his villa in the Xuanyuan Empire. With her modern medical skills and an ancient ring that contains its own space, she kills the cruel servants, sets fire to Prince Zhao’s residence, and beats a drum to plead her case, asking the emperor to grant her a divorce. Xuanyuan Moxuan is a battle-hardened prince of the Xuanyuan Empire, poisoned and gravely ill, the legitimate heir of the Zhou royal family, and the master of Lingxiao Pavilion. When they first meet, Yan Jiuge drops from the sky into his arms. The next time, she is tossed into his carriage. Seeking revenge, Yan Jiuge clings to her Ninth Imperial Uncle for support. But Prince Zhao, the second prince, repeatedly obstructs her escape from her predicament for his own benefit and even tries to sabotage her relationship with her Ninth Imperial Uncle. Yan Jiuge relies on the Ninth Imperial Uncle’s power to take revenge, yet insists on remaining independent, torn between love and her own sense of worth. Meanwhile, if the secret of Xuanyuan Moxuan’s royal Zhou lineage is exposed, he will be hunted by every faction. Newly arrived in the ancient world, Yan Jiuge has little power, and her past marriage to another man leaves her feeling inferior in matters of love. As their relationship develops, Liu Yiyi’s affection causes further complications, and Yan Jiuge mistakenly believes Xuanyuan Moxuan has feelings for her. More urgently, Xuanyuan Moxuan’s poison leaves him near death, and Yan Jiuge must find an antidote before time runs out. As a transmigrator, she also faces countless obstacles in the form of backward customs and institutions. But the two join forces and overcome one crisis after another. As their love deepens, Yan Jiuge finally gets her revenge, Xuanyuan Moxuan is cured, and together they break the old system and build the new world they dreamed of.
