The heroine is originally a "salted fish" who just wants to live a stable life in the harem. With her "Buddhist" posture and superb disguise skills, she strives to become the least existential person in the harem. However, her unique survival rules unexpectedly attracted the sinister emperor who was tired of the hypocritical fights in the harem. The emperor saw through her exquisite mind and intelligence and tenacity under her "indifferent" appearance, and became deeply interested in her. From then on, one just wanted to lie down and the other wanted to be pampered alone. Under the overt and covert protection and "connivance" of the emperor, the heroine was forced to be involved in a series of palace conspiracies. She doesn't take the initiative to harm others, but she can always deftly resolve crises and make those who harm her suffer the consequences. In the process of jointly dealing with internal and external troubles time and time again, the two hearts gradually got closer. The heroine was eventually promoted from a low-level talent who just wanted to save her life to the throne of the queen by the sinister emperor, composing a sweet love song of the palace "You are responsible for the power and scheming of the world, and I am responsible for the beautiful salted fish". The highlight lies in the anti-routine "lay down and win" palace fight, as well as the sweet interaction between the male and female protagonists who see things through without telling them, and pull to the extreme.
