Female protagonist: Shen Qinghuan, a graduate student in the Department of Modern History and a master of palace fighting games, accidentally traveled through time and became the concubine of the prime minister of the Feng Dynasty, and was forced to enter the palace for the draft. She is weak on the outside but strong on the inside, proficient in historical maneuvers, and is good at "pretending to be a pig and eating a tiger". Her ultimate goal is to live in the harem and become a salted fish, but she is forced to upgrade along the way.
Male protagonist: Xiao Jingheng, a young emperor of the Feng Dynasty, who appears to be romantic but is actually very serious. He has the ambition to be a wise king but is hampered by the Queen Mother and powerful ministers. When he first met the heroine, he regarded her as a chess piece. Later, he was gradually attracted by her unique intelligence and independent character, and fell into conflicting emotions.
World view: The Feng Dynasty is an imaginary dynasty. The harem system is strict but there are historical loopholes that can be exploited. The old and new forces in the court are fighting, and neighboring countries are watching.
