Qin Ge, a 21st-century engineering genius, is transported into the body of a dying, impoverished scholar outside Xianyang after a bronze compass in his lab behaves strangely. As he teeters on the brink of death, the Great Qin Revival System binds itself to him and awakens. It can scan historical figures' potential, unlock blueprints for modern technologies such as the curved-plow and papermaking, and even use a Beauty Almanac to mark his bonds with the renowned women of the age.
When he first meets the young Ying Zheng, newly returned from Zhao as a hostage, Qin Ge uses the System to foresee danger and help him escape a bandit ambush. His forward-thinking strategy of strengthening both agriculture and military might astounds Ying Zheng. The two share drinks at a tavern, swear brotherhood despite having different surnames, and pledge to rule the realm together. From then on, Qin Ge uses the System to make his way into the heart of power, beginning with the promotion of improved farming tools and the invention of Qin paper, which shocks the court.
He oversees the construction of cement roads and a new Zhengguo Canal, bringing thousands of miles of fertile farmland to the Guanzhong region. He forms the Black Armor special forces and develops an early form of gunpowder, helping Ying Zheng suppress rebellions and conquer the six kingdoms. He also joins forces with celebrated women from across the realm: Tian Linger, a farmer's daughter, manages agriculture; Shadow Butterfly, an assassin, serves as his guard; Princess Mi Li of Chu offers up the south of the Yangtze; and Suwen, an heir to the title of Medical Sage, saves soldiers and civilians. Each woman lends her strength as they build a golden age for Great Qin.
From impoverished scholar to Lord Wu'an, from swearing brotherhood in the streets to standing beside the First Emperor at court, Qin Ge uses modern wisdom to rewrite history. He makes the Qin dynasty rich in grain, strong in arms, and prosperous in trade, breaking the fate of a dynasty destined to fall after only two emperors. When the beauties of the six kingdoms gather in Xianyang and the System's ultimate mission begins, the brotherhood between Qin Ge and Ying Zheng, along with the legend of the women surrounding them, will write an epic on this ancient land far grander than anything recorded in the history books.
