Yu Xiyan, a genius of metaphysics in the 21st century, accidentally transformed into a fake daughter of an ancient prince, with a compass in her left hand and a scalpel in her right hand, and became a supernumerary work in Dali Temple. I wanted to find out the truth about the death of the deceased and retire, but I found that I could see the last scene of the deceased through the wound on the corpse - the drowned bride in a red wedding dress crying from the corner of her eyes, the prime minister's legitimate son with his severed finger stuck in the chest, the bones dug out from the dry well in the cold palace were actually wearing the golden hairpin of the queen mother... When the autopsy results frequently pointed to the secrets of the palace, Yu Xiyan was involved in a bigger conspiracy. The seemingly glamorous Imperial Master Xie Wujiu always "encounters" her by chance when she is investigating cases, but little does she know that this man can hear her crazy complaints. The most terrible thing is that when the two people touched the body at the same time, the deceased actually spoke!
