Lin Chen, a modern forensic doctor, is transformed into a cowardly policeman at the bottom of the Dayong Dynasty. His parents are dead and everyone can be bullied. At the beginning, there was a murder case in a grain dealer's secret room. Everyone concluded that it was "an adopted son who murdered his father." Seeing that the case was about to be unjust - he overturned the verdict in public, overturned the autopsy conclusion in three sentences, and identified the real culprit based on a trace of medicine on the fingertips of the deceased.
From then on, Yunxi County exploded.
Does the county magistrate believe in ghosts and gods? He exposed on the spot that the "ghost house asking for life" was actually a murder by Shimei. Are all arrests based on torture? He used blood, dust, and shoe prints to spell out the complete scene. Everyone said, "This was done by ghosts." He opened the body's mouth and nose and said word by word, "This was poisoned."
A poisoning led to a series of murders, and a twenty-year-old case came to light, and a "Qingtian Grand Master" named Shen Wenyuan was among them. The protagonist was transferred from the mountain to the state capital. He knew it was the Hongmen Banquet, but he stepped into it alone - because he knew that the truth was not in the confession, not in the official authority, but in the ironclad evidence.
