Ning Shuyan, the concubine of Ningyang Hou Mansion, once entered the palace, and she knew that there was no true love in the harem, and she could only use her femininity as a mask and intelligence as a weapon. She is gentle and harmless in front of others, but she is careful at every step behind others. She cleverly breaks the poisonous abortion scheme, resolves the difficulties caused by her beloved concubine, and uses her strength to check and balance the Sixth Palace. Emperor Xiao Yu was initially attracted by her beauty, but was gradually attracted by her double-sided charm. From a whim, he turned into a devoted lover. Faced with birth prejudice, harem siege and family exploitation, she does not seek fame, but only strives for real power and the emperor's heart. In the end, Ning Shuyan used her scheming and tricks to make a comeback, rising from a humble talent to the master of the harem, creating a legend of a palace battle in which she was the only one to be favored step by step.
