Shen Zhaoning dressed up as a young nobleman in the harem and wanted to live alone and wait to die. Unexpectedly, Emperor Zhao Che always had a complicated look on his face every time he looked at her - only later did she find out that she looked a lot like the emperor's Bai Yueguang Cui Lianyue. Facing the eager Concubine Xiao and Concubine Shu, who hides a knife in her smile, Shen Zhaoning decided to use his top talent: acting. Acting delicate and frail to gain sympathy, acting virtuous to win allies, and even acting affectionate enough to make the emperor think she loved him to death. Her acting skills rose all the way to the rank of royal concubine, and she also gave birth to a smart son. Seeing that life is happy, Bai Yueguang suddenly returns to the palace. The emperor said, "You can never compare to her." She was thrown into the cold palace, and her son was made to kneel down for three days and had a high fever. Under the cold palace wall, Shen Zhaoning held her dying son in her arms, finally tearing off all pretense. She began to make a careful plan: using rumors to kill Concubine Xiao, using housekeeping power to make Concubine Shu suffer the consequences, and even educating her son to transform from a cold palace prince to a favorite for the throne. And when the emperor finally discovered her true nature and wanted to get back together, Shen Zhaoning took out a divorce letter: "Your Majesty, this is the edict to abolish the queen that you wrote in your own hand. I changed a few words."
