Chen Mo, a medical student in the 21st century, accidentally traveled to the Yongle period and became an assistant at the Yizhuang of Shuntian Prefecture. Armed with the knowledge of modern forensic medicine, he used scalpels as pen and corpse spots as ink to pursue the truth in the fog of the Ming Dynasty: accurately infer the time of death from the shape of corpse spots, identify the source of poisons by using the composition of stomach contents, and expose the disguised scene using skin scrapings between fingernails. Faced with the county magistrate's doubts and the government officials' rejection, he used a silver needle to test the poison to show the authenticity of the seal, judged the authenticity from the perspective of scars, and unearthed hidden evidence from the silent corpses. When modern medicine encounters ancient mysteries, let's see how he uses his microscope-like insight to tear apart the veil of conspiracy between the yellowed pages of "The Collection of Wrongs" and write a forensic legend.
