A top modern history student transmigrates into the body of Fusu, only to face a forged edict ordering his death, concocted by Zhao Gao and Li Si from the start. With his life hanging by a thread, he exposes their plot before everyone using modern political savvy and his knowledge of history. By precisely reading Meng Tian's mindset, he successfully persuades the general, who commands 300,000 elite troops on the northern frontier, to switch sides, taking control of the border army without bloodshed. He then marches south under the banner of "purging the emperor's enemies." On the way, he applies modern management principles to tighten military discipline and streamline supply lines, winning over the commanderies and counties along his route through sheer force of superiority and building momentum for the whole realm to rally behind him.
