In the last years of Emperor Jing of the Daqi Dynasty, the prosperous age was in decline. The emperor indulged in elixirs, and the power of the court fell apart. The prince Renrou, the second prince were domineering, and the third prince was dormant. Under the three-legged pattern of fighting for the heir, a chess game involving blood feud and righteousness quietly unfolded.
He was originally the son of Xiao Ce, the Marquis of Zhenbei who guarded northern Xinjiang. Three years ago, Xiao Ce was accused of "collaborating with the enemy and treason" because he refused the second prince Zhao Lin's order to mobilize troops privately. The entire family of the Marquis of Zhenbei was executed. Xiao Jue was studying at Imperial College in Beijing at the time, but was sent out of the city by his father's former subordinates. Later, he changed his name to "Wei Jue" and first sneaked into the capital as a down-and-out merchant. While running a grain store to accumulate financial resources, he secretly contacted his old subordinates and collected evidence. He has learned the art of war and strategy from his father since he was a child, and is proficient in understanding people's hearts and deducing situations. He has also learned the skills of disguise and deciphering secret messages. Due to the family blood feud, he appears to be gentle and affectionate, but in fact he is thoughtful and forbearing. He wants to overturn the family's case but does not want to become a pawn of power.
With meticulous political layout as its bones and complex human struggle as its soul, it composes a heroic tragic song about loyalty, hatred, ambition and responsibility in the turbulent times of dynasty changes.
