She is a top killer codenamed "Nightingale", with blood-stained hands and a heart as cold as iron. After a betrayal, she opened her eyes and became the most humble concubine of the Duke's Mansion in Fengqi Town - Lu Zhao.
In this world where women are superior to men, the former murder weapon is trapped in a sick and weak body, and is bullied with blind eyes. Chronic poison corrodes this body, and the open and secret arrows in the house are more deadly than the poison.
When her eldest sister pushed her into a desperate situation again, the dormant "Nightingale" woke up.
A silver needle can save people, but a hidden blade can also kill people.
One hand hangs a pot to help the world and shocks the world, and the other hand turns the clouds and rain and disturbs the court. The seventh prince Xiao Jing's foresight behind his gentle mask, and the fiery and sincere pursuit of the tiger son Qin Fang have all become her pawns in this whirlpool of power.
However, when she moved the capital in the name of "Master of the Holy Hand", when she stirred up the imperial power situation with her cold eyes, the aloof empress cast a scrutinizing gaze...
All she wants is freedom from the prison.
But if the world insists on her bowing her head, she doesn't mind - let the world change its rules!
