A modern young man accidentally traveled through time and became Xie Yun, the powerless seventh prince of Yu. He has been cautious in the palace since he was a child, but he still cannot escape the dispute over the heir apparent. The ambitious third prince secretly set up a dead end. Luo Zhi framed him for treason and was thrown into a prison and sentenced to death. On the verge of death, Xie Yun successfully activates the Heroes Summoning System, which can summon all the civil servants, generals, and extraordinary talents of China. He won the emperor's mercy by virtue of his extraordinary acting skills and was exempted from death penalty. As an eighth-grade captain, he led 500 old and weak soldiers to be exiled to Yinchuan to guard the border. Taking root in the western frontier, Xie Yun recruited talents, trained elite soldiers, pacified the people, and developed the economy. He repeatedly defeated the barbarians in the grasslands and quickly established a foothold at the border. There is a turbulent undercurrent in the court, and there are many doubts about the old case. The third prince, who is afraid of his rise, takes the risk to kill the king and usurp power. Xie Yun, armed with powerful soldiers and unparalleled advisers, angrily raised his troops and marched south to the side of the Qing Dynasty. He suppressed the disputes in troubled times, destroyed the decadent empire, and finally established a unified dynasty and ascended to the throne of the emperor.
