Night Patrol

Others transmigrate and become nobles or ministers; Shen Yan transmigrates and directly gets a death row package in the imperial prison, with only three days left until his whole family is cut in half at the waist. In his past life, he was a forensic doctor in a major crimes unit, proficient in trace examination and criminal reasoning. His soul transmigrated into the son of a disgraced official in the Great Jing Dynasty, caught up in an ironclad case of a mysterious fire that wiped out a family. The three judicial departments have concluded, the Night Patrol Bureau has filed the case, and powerful figures have conspired to frame them. Everyone believes the Shen family are traitors to the nation and doomed. But Shen Yan knows well: there is no perfect crime in this world, only traces that have not been discovered. In the imperial prison, he uses his forensic knowledge to solve the case from afar, shatters the ironclad case in court, clears the Shen family's name, and is exceptionally admitted into the Night Patrol Bureau, which governs all mysterious cases under heaven, becoming a low-level patrol officer. In the three hundred years of Great Jing, undercurrents surge. Demons walk at night, sorcerers cause trouble, and the transcendent forces of Confucianism, Daoism, and Buddhism hide behind the imperial court. Behind each folk mysterious case lies a millennium-spanning chess game of gods and demons. While others cultivate and fight with magic, he relies on autopsies, traces, and logic to solve one unsolvable murder after another; Powerful figures want to use him as a pawn, and transcendent beings want to sacrifice the human world. Shen Yan holds the laws of the human world in his hands. In the long dark night, he investigates mysterious cases, battles powerful ministers, defeats demons and evil spirits, and overturns the ancient chess game. With a mortal body, he can still govern the long night; as a mere patrol officer, he dares to decide right and wrong for the world! — Description from novelcodex.orgFull novel: Night Patrol — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
