Under the great peace of the Zhou Dynasty, undercurrents surged and strange cases occurred frequently.
A modern forensic doctor travels back in time to become detective Lin Ci, living in an ancient era where etiquette is strict and technology is lacking. He uses a pair of keen eyes to examine autopsies and identify injuries, and uses scientific reasoning to solve strange and confusing situations.
Every corpse tells the truth; every scar points to the real murderer.
He does not seek power or be confused by rumors. He uses corpses as evidence and the law as a sword to uncover the conspiracies and crimes covered up layer by layer.
This is the perseverance of a police officer and the belief of a forensic doctor - the truth never decays.
