Who would have thought that with the post "Will Qin die after Fusu succeeds to the throne?", Fusu would be the person involved in the next second! The beginning was hell: before the wind and cold healed, he was faced with a death crisis. He relied on a lighter to survive; armed with modern agricultural knowledge and equipment blueprints, he used lime moisture-proof bags to reduce the loss of grain and grass, and used an improved trebuchet to defeat the Huns' harassment, and gradually gained a foothold in the military camp. Later, Zhao Gaolisi's Sand Dune conspiracy was exposed, the first emperor was rescued, and he was established as the prince. He also quelled the rebels and pacified the people, vowing to rewrite the short-lived fate of the Qin Dynasty. But will Xiang Yu, who fled to Jiangnan, and Liu Bang, who fled to Bashu, really give up?
