Empress Dowager Turns 18, Reforms Disobedient Princes

After Empress Dowager Xie Nngxue dies suddenly, her soul travels back fifty years to an 18-year-old county magistrate's daughter with the same name, where she enters the palace as a maid. Discovering the Great Liang dynasty is in decline, she finds her son the retired emperor has been poisoned with sleep-inducing venom, her grandson the emperor is controlled by Empress Noble Consort Li Sihan using a twin-life venom, and her great-grandson Prince San is arrogant and domineering. Using her medical skills and strategy, Xie Nngxue cures the poisons, exposes the noble consort's conspiracy, defeats Grand Tutor Li's rebellion, reorganizes the government, educates the princes, and ultimately restores the Great Liang to its former glory.
