Great Qin: Another Person from the Future Has Fallen into My Realm

[The First Emperor is the protagonist, with a relay of transmigrators, some victorious and some defeated] In most stories about transmigrating to the Qin Dynasty, the protagonist is the transmigrator. This one is different. The protagonist is Qin Shi Huang. Each time the Imperial Seal of China lights up, a visitor from a later era falls into the Qin Dynasty. Some know medicine, some understand warfare, some have seen how a dynasty rots to its core, and some have just lived through the night their country fell. They don’t know who will arrive next, and there’s no way a few words can make the entire court bow to their will. The ancients aren’t fools, and the First Emperor is no fool either. Change an old policy, and you’ll have to face everyone who benefits from it. Save one group of commoners, and people elsewhere may have to pay the price first. A visitor can win or lose, and leave their mark, but they cannot remain in this era forever. Their role is to warn the Qin Dynasty about the pitfalls that future generations have already encountered. As for how this realm should change, that decision belongs to Ying Zheng alone. The Imperial Seal is glowing again. Who will fall through this time?
