Yang Songnian was an office worker in the 21st century. By chance, he traveled back in time to ancient times. In ancient times, his father was a general of the dynasty. He found that the world was unfair everywhere. He went against the will of Qiu Wei and entered Dali Temple to change the world. However, he offended the emperor and ministers and was deprived of his rights. He followed his father to send troops to resist foreign attacks. At this time, the emperor died without establishing a prince. The six princes all had ambitions and wanted to seize the throne, leading to chaos in the world. His father Yang Yong was also killed by the second prince who had just succeeded. Yang Songnian led the remaining soldiers to flee to the south. After several years of development, he finally returned to Kyoto and established a new dynasty.
