Shen Yuan, a top modern forensic pathologist and criminal profiler, unexpectedly transmigrates to an ancient dynasty where the legal system is still in its infancy and investigative technology is extremely backward. He is forced to take over the capital’s most ill-fated, universally shunned position: keeper of the public mortuary and coroner. He only wants to use his expertise to do his job and quietly study the mysteries of the human body in this era. But with investigative techniques so advanced they leave the locals in the dust, he cracks one bizarre case after another, clears the names of the wrongfully accused, and makes the dead “speak.” From a despised “corpse collector” to a “living King of Hell” feared by officials and commoners alike, he quietly rewrites this era’s laws and notions of justice.
