Gu Huan, a modern history graduate student, accidentally fell down a well while cleaning Han Dynasty bamboo slips. When she opened her eyes, she had become the orphaned descendant of Gu Yan, a founding general of the Great Jing Dynasty. To cover up his ancestor's treason, the chancellor Wei Yong burned all the founding-era historical records, branded the entire Gu family as traitors, and sentenced them to death. Only Gu Huan survived, living in obscurity in a small village at the foot of Zhongnan Mountain. While gathering herbs in the mountains one day, she stumbled upon a fragmentary Mohist mechanical manuscript left by her ancestor. It not only recorded the full truth about the wrongful case from fifty years earlier, but also contained diagrams for long-lost papermaking techniques and movable-type printing. With Wei Yong's falsified history due to be finalized and placed in the archives in three months, Gu Huan resolved to use her modern knowledge and Mohist skills to recreate the bamboo records that documented the truth and make it public before the deadline. Once Wei Yong learned of her plans, he pursued her relentlessly and shut down every channel of circulation. The imperial family also branded her a spy intent on disrupting the court and issued a warrant for her arrest. With neither money nor influence, this orphaned girl had to oppose a powerful minister who had controlled the court for twenty years, while exposing the enormous lie woven by those in power before history could be altered forever. If she failed, the injustice suffered by more than three hundred members of the Gu family would remain buried forever, and the people of the realm would sink into the mire of Wei rule.
