Su Wanwan, who was born into a family of officials but saw through everything when her family was destroyed in a party dispute, was sent to the palace as a substitute for the daughter of the late General Bai Yueguang. Her only goal of survival is to "disappear", eat and wait for death, and strive to be relegated to the cold palace as soon as possible and enjoy her old age. However, every time she behaves in a bad way, in the eyes of others, it becomes an unfathomable and top-level palace fighting skill. She doesn't compete for favor, and is considered by the sinister emperor to play hard to get, which is unique; she is irritating others just because she is too lazy to socialize, but she always accidentally reveals her plot; she is kind to others because she is afraid of trouble, but she has gathered the most loyal slaves. In this way, a woman who just wanted to be a salty fish accidentally climbed to the pinnacle of power in an environment where the whole harem went crazy, won the emperor's heart, and finally realized the grand life ideal of "paid vacation, life-long ruin".
