Introduction: When the Six Kingdoms were first destroyed and the world was unified, two foreboding canopies appeared in the sky, comparing the two life trajectories of Fusu and the two endings of Daqin. Left curtain: Fusu Yu commits suicide by observing Confucian etiquette, an uprising sweeps the world, and the Qin Dynasty is destroyed; right curtain: Fusu understands the true meaning of unification, ascends the throne as Emperor Taizong of Qin, conquers the Huns in the north, and achieves peace at home. Ying Zheng in Xianyang Palace quickly calmed down and issued multiple decrees to maintain stability and control. Wang Jian and Li Simengtian worked together to assist the government. Zhang Liang, who was far away in old Korea, had a glimpse of the future of a strong and powerful Qin, and the anti-Qin plan reached a deadlock.
