The modern aloof royal sister Shen Qingtang traveled through time and became the deposed Queen of the Cold Palace in the Great Yan Dynasty. The original queen was thrown into the Cold Palace due to a frame-up of her family's "collaboration with the enemy". Relying on the calmness and decisiveness of a modern corporate CEO and the cleverness of an ancient lady, she first defuses the provocation of the hypocritical concubine, and then exposes the Green Tea Concubine's conspiracy, gradually finding out the truth about the family feud. In the process, she unexpectedly encountered the emperor Chu Zhaoyun, who was suave on the surface but calm and mysterious in reality. From testing each other to going both ways, she eventually became the favored queen of the group, promoted the reform of the harem, ended the grudges of three generations, and achieved great success.
