A top student of Jiang University who graduated from the Forensic Qin Ming Advanced Training Class, once traveled through time, he became Shen Shuyan, an orphan from the Hou Mansion whose family was exterminated. The beginning was hell mode: 300 members of her family died tragically, leaving her alone. She was also accused of having an affair with a thief and was about to be executed. Official conclusion: Bandits robbed and killed in passion. But in Shen Shuyan's eyes, every blood stain on the scene and every wound on the corpse were silently shouting: There is another murderer! In order to find out the truth, she put away her ladylike behavior, rolled up her sleeves and walked into the morgue. Uncle Wu Zuo was fighting: "Ms. Shen, Miss Shen, this place is unlucky and women shouldn't come here!" Shen Shuyan said expressionlessly: "Craniotomy, examination of the residue in the stomach, and the last meal the deceased ate before death are the key to solving the case." The minister of Dali Temple was shocked: "What? Using pig skin and ink, you can recover the murderer's fingerprints?" She used the knowledge of modern forensic science as a knife and the simple conditions of ancient times as an edge to cut through the layers of fog and let the bones speak. One after another strange cases were solved under her hands, and Shen Shuyan's name resounded throughout the capital. But all the clues vaguely point to the powerful, cold and ice-cold prince of the current dynasty - Xiao Ce'an. Everyone said that His Royal Highness was the talisman of her family and her biggest enemy. But it happened to be this biggest enemy who saved her in danger time and time again and blocked all the open and secret arrows for her. Until that night, he blocked her under the palace wall, with overwhelming regret and love in his scarlet eyes. His voice was hoarse and he asked word by word: "A Yan, do you know why I saved you alone on the night when the family was destroyed?"
