Zhao Yu, a graduate student in the Department of Modern History, accidentally traveled to the period of the Five Hus and Sixteen Kingdoms and possessed the body of "Shi Min" (the prototype of Ran Min), a general under the Jie Zhao regime in the north. At this time, although Shi Min was the adopted son of the Jie Zhao clan, he was highly suspicious because of his Han identity and was at a critical turning point in his life. Relying on his prediction of the direction of history, Zhao Yu is determined to avoid the tragic ending of the prototype character, protect the Han people in troubled times, reshape the northern pattern, and at the same time show the various social conditions of this period.
