After his divorce, exploration team member Shi Jun was driving an expedition pickup truck when he accidentally transmigrated to the grasslands of the Western Regions at the end of the Han dynasty. There he met A Jiao, the daughter of a tribal chieftain. Using his modern knowledge, Shi Jun repeatedly resolved crises facing the grassland tribes, became their leader, and married A Jiao. Shi Jun then drew on his expertise in exploration to lead the tribes to rapid growth, build a powerful army, and defeat the Xiongnu. Later, determined to prevent the land from being strewn with bones and villages from falling silent for a thousand miles, Shi Jun led his army through the passes and entered the fray among the rival powers of the Three Kingdoms. He defeated warlords one after another, ended years of warfare, developed agriculture and hydraulic engineering, and saved the people from suffering.
