Policewoman Lin Zhao died heroically in a mission, and when she opened her eyes again, she became the most inconspicuous sixth lady in the Dingyuan Marquis Mansion in the Great Zhou Dynasty. Her biological mother was humble and her life was like a piece of grass.
In this gorgeous cage, the aunt is hypocritical, the sisters are at odds, and every step is like walking on thin ice. But why was Lin Zhao afraid? She kept her cool and turned modern criminal psychology and criminal investigation methods into invisible sharp blades. She used every trick in Bo Yun's weird back house and worked step by step.
An unexpected "poisoning case" caused her slender figure to fall into the eyes of the powerful regent Xiao Jue. She peeled off the cocoon, restored the truth, and revealed her edge. Xiao Jue took this as a contract, coerced and lured her, and recruited her as his secret spy placed in the courtier's back house.
From then on, Lin Zhao lived a double life: during the day, she was a concubine of the Marquis who hid her clumsiness and foolishness, and kept herself to herself; at night, she was a "brocade-clad spy" who spied on intelligence for the Regent and solved unsolved cases. While she was dismantling the house fighting conspiracy in the pile of makeup, she was also investigating the mysterious case in the court at the center of the power whirlpool.
As she approached the core of power step by step, she discovered that the death of her biological mother, the secrets of the entire family, and even the shocking case of the previous dynasty all pointed to the same truth. And her relationship with the cold-faced prince also changed from using each other to relying on each other to fight side by side...
