Forensic doctor Su Xiaoxiao died on a cliff and woke up as the prime minister's legitimate daughter who was pushed down the lotus pond.
The murderer was her concubine, and the mastermind behind the murder was her fiancé, the prince. As for her mother, she "died of a hemorrhagic collapse" ten years ago - she had her mother's bones examined and found out that it was aconitine poisoning.
She only has a jade pendant, two hands, and forensic skills. Without a microscope, she used a silver needle to test for poison. Without a chromatograph, she used lime water to measure aconitine. With no witnesses, she lets the corpse speak.
The first person to die was the manager of the Liu Family Drug Store, whose throat was sealed with a knife. The second person to die was the grocery store owner who knew about it, but he was also silenced. If she checks one, the other will die. All clues point to the same person - the current prince. But behind the prince, there was a hand that could change everything.
She climbed over the wall to explore at night, and was stabbed in the shoulder. The person who rescued her was the Prince Regent. The cold-faced King of Hell was determined to kill, but he was willing to squat on the wall all night just to hear if she made any movement.
He said: "Ten years ago, I failed to protect your mother. Ten years later, I will never fail again."
But what she didn't know was that he was the one who had been secretly delivering daggers, delivering prescriptions, and blocking knives for her. What she didn't know was that at the end of her investigation, it was not the prince or Mrs. Liu who wanted to be brought down, but the woman sitting behind the curtain twisting the beads.
