A special forces soldier transmigrates into the body of a wretched border guard in ancient times. With little food, brutal labor, and his life hanging by a thread, he saves a beauty and marries her. Using modern special operations tactics, he repeatedly defeats powerful enemies and rises through the ranks by earning military honors. He gathers fallen talents and builds an elite new army, recruiting capable people from across the land. He forges a battle-hardened force of his own, seizes control of the border, vies for the Central Plains, sweeps across the realm, and unifies the Nine Provinces!
