"Dayin Dynasty", the Yin Dynasty has unified the world for a hundred years after the seven kingdoms fought for hegemony. Now the court is decaying, the clans are divided, and foreign invasion is ready. This is a world where "chess" is used as a metaphor for "power". The nine-level Zhongzheng system divides people into nine grades, and family status determines destiny.
The eldest son of the "Lanling Shen family", one of the four original wealthy families, when he was ten years old, his father was involved in a rebellion, and the entire Shen family was executed. He was demoted to slavery because he was young and escaped death, and lived in the market incognito. On the surface, he appears to be a sickly and gentle scholar, but in reality he harbors a deep hatred. He uses the world as a chess game and vows to overthrow the decadent dynasty.
