I Disrupted the Warring States Disputes

Among the seven heroes of the Warring States Period, Qin was the strongest and South Korea was the weakest. A child fell from the sky and appeared in South Korea. The great Qin Dynasty is iron-clad, South Korea is in great danger, and where will this child with some strange memories go? PS: Although South Korea will be destroyed, it is still possible to change the order of destruction. There is no golden finger in this novel, only some future memories, and it is incomplete. The protagonist has no idea about the history of the Spring and Autumn and Warring States periods! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
