The South Vietnam Dynasty is in turmoil. The third prince Liu Yebai is a dandy and a wise man in the eyes of the world, but secretly he keeps a low profile and secretly investigates the truth about the tragedy of his mother's family. The prince is losing power day by day, undercurrents are surging in the court, and Su Zhilan, the daughter of a powerful minister, is also pushed onto the stage of political intrigue. The two became allies by chance. They were both chess players and pawns, and they worked together step by step in the confrontation between fate and emotion, justice and selfishness. The story progresses in four volumes, from undercurrents of minor conflicts and palace embarrassments to party disputes in court and room, and through the grand conspiracy of ups and downs of life and death. In the end, Liu Yebai cleared the fog, unified the world's power, and grew up from the cocoon to become a butterfly. He not only looked at the world with a smile, but also realized the feelings of benevolence and filial piety as a son of man. On the basis of a balanced interspersion of witty dialogues and humorous scenes, the story is fast-paced and suspenseful, closely following the core theme of palace intrigue.
