Modern historian Li Ming accidentally traveled back in time to the fifth year of Jian'an while studying historical materials about Soochow, and became Sun Quan who had just inherited Jiangdong's foundation. Facing the turbulent situation after Sun Ce's assassination, he used modern political wisdom and historical insight to implement reforms with the assistance of Zhou Yu, Lu Xun and other famous ministers: he formed a naval army to resist Cao Cao's southward march, and joined forces with Liu Bei to win the Battle of Chibi; he designed a surprise attack on Jingzhou in white clothes across the river, and defeated the Shu army in the Battle of Yiling; after proclaiming the emperor, he implemented the farming system, salt and iron official camps, and opened up trade routes between Yizhou and Liaodong. However, behind the peak of power were the fratricidal battles between the two palaces, the shock to the government and the public caused by Lu Yi's anti-corruption campaign, and the diplomatic crisis caused by Gongsun Yuan's misjudgment in his later years. While rewriting history, Li Ming also had to face the price of the power struggle - the choice between loyalty and betrayal, family affection and interests. When he died of illness in Jianye at the age of seventy-one, he left behind not only a solid Jiangdong foundation, but also a "legend of the time traveler's governance" that has been debated by later historians.
