Qu Zhan, King of Yan in Youzhou, died mysteriously, leaving behind two sons with very different personalities. The eldest son, Qu Yiwu, was brave, warlike, and ambitious; the second son, Qu Yizhang, was weak and quiet, and was always despised by everyone. When everyone thought that the throne of King Yan would be successfully succeeded by Qu Yiwu, the seemingly incompetent Qu Yizhang was secretly setting up a chess game. He used retreat as advance and went to the frontier to accumulate strength. In this troubled world, what he wants is not only to survive, but also to find out the cause of his father's death, regain everything that belongs to him, and finally win the world in this decadent card game of the late Han Dynasty.
