During the Yuanfeng period of the Northern Song Dynasty (1078-1085), Wang Anshi's reform had been going on for more than ten years, and the struggle between the old and new parties became more and more intense. The story revolves around a long-lost authentic painting of the "Thousand Miles of Rivers and Mountains" - it is said that this picture hides the secret of a huge fortune left behind by the previous dynasty. Forces from all sides: the old and new party members in the court, the mysterious organization "Photo Studio" in the arena, and the covetous Liao spies are all vying for this painting.
