Because of certain things, Su Zhou voluntarily entered the palace and became a concubine to the emperor who was in his fifties.
Of course, this is only on the surface. The old emperor only has one princess at his knees. The vassal kings in various places openly obeyed the old emperor's advice and secretly recruited troops and won over the important ministers in the court. There was a possibility of rebellion at any time.
The old emperor took advantage of the vassal kings from various places to come to Beijing to congratulate him and detained the heirs of the vassal kings from various places. He chose the euphemistic name to select those who could inherit the throne from among the clan's nephews. However, most of the heirs of each vassal king died in Beijing. Although the vassal kings did not take advantage of this incident to get angry, the old emperor was worried that they were just trying to make him relax his vigilance.
Therefore, Su Zhou was forced to assassinate these vassal kings and regain the power of the vassal kings in his hands. By the way, he also investigated who killed the prince heir in Beijing.
It's probably the story of the male concubine killer x the feudal prince's heir
