Cai Ting is an outstanding sniper. While on a mission, he is caught in a terrifying thunderstorm, and a bolt of lightning strikes his head. Just when he thinks his soul is about to vanish, he discovers that he has transmigrated to the final years of the Sui dynasty!
Seeing Emperor Yang of Sui endlessly conscript farmers to dig deep trenches, build the Western Garden, construct the eastern capital, excavate canals, build the Great Wall, repair palaces, chop trees for ships, and cut mountain roads, Cai Ting unhesitatingly chooses to join the Wagang Army.
