Modern forensic doctor Cheng Wan died on the job while chasing the murderer. When she opened her eyes again, she became Wen Xiaoman, the legitimate daughter of the Dingbei Palace who had been living among the people for thirteen years. The adoptive father returned half of the jade pendant before his death, and the carriages and horses of the royal palace in Beijing were finally found. Acknowledging the ancestor and returning to the clan is just the beginning: the step-concubine set up a trap, the fake daughter pretended to recognize her, the palace banquet was poisonous and the wine was poisoned, and the mother's family's unsolved case all pointed to the old case of the biological mother "falling off a cliff and dying" thirteen years ago. Her skills in autopsy and case-solving gradually became famous in the capital, and she uncovered step by step the truth that her biological mother was still alive and imprisoned in the nunnery for thirteen years. Betrothal, wedding, abolition, war, palace coup, new dynasty - she was a wild girl who returned from the palace, to a "strategist" in the northern army, and then to the queen of Fengyi World. She didn't ask for much in this life: for the dead to speak, for the wronged to be redressed, for her mother to return home, and for her loved ones to ascend to the throne of God safely. And her biggest trump card is never anyone, but herself.
