He is Pei Jin, the commander of the Jinyi Guards of the Ming Dynasty, the "Living Yama" tacitly approved by the emperor. It is common for the powerful to bow their heads at the point of the sword and massacre their entire family in one night. His methods are cruel and his heart is as cold as iron. He only believes in the "truth" forced out by the files in his hands and the instruments of torture, without knowing what it is.
A "female corpse" fished out of the moat turned his world upside down. Xie Chenbi, the orphan girl of the Xie family who was "snapped" by him seven years ago, used the same brand on her collarbone as his childhood enemy and a crude jade cicada stained with blood to tear open the bloody past. The jade cicada was the evidence that his mother swallowed in despair before she died; and the brand pointed to the "ghost market" where children were trafficked and caused countless human tragedies.
An even crueler truth followed: the Liu, Chen, Zhang, Xie and other official families he was so proud of to "purge" and bloodbathed with his own hands were not treacherous ministers, but the culprits who participated in the trafficking and pushed him and countless children into hell! They are just the minions and scapegoats of the real "evil ghosts" such as the eunuchs in the palace and the founding fathers. He, the emperor's sharpest knife, spends his life killing people, but he is clearing the door for the real enemy!
The mother's weeping figure and Xie Chenbi's cold accusation burned away Pei Jin's past beliefs. Extreme hatred and destructive madness swallowed him up. He turned his blade, and in the name of "secret order", he brazenly launched a bloody purge that shocked the empire. The Shadow Guards rode like hell asuras, attacking Dongchang at night and trampling on the Duke's mansion. The powerful eunuch and the century-old nobleman were dragged into prison wailing under the sword and crossbow.
When the morning light pierced the haze of the imperial capital, the gate of Fusi in Beizhen opened, leaving only blood rising to the sky. Pei Jin's mysterious robe was soaked in blood, and he walked towards the abyss of the prison on the long steps paved with the blood of the powerful and his own. This hell on earth he built with his own hands eventually swallowed up the real evil ghost and imprisoned himself forever. The door of the bloody prison slammed shut behind him, leaving only a winding dark red blood mark, telling the story of this fatal battle. The blade of authority will eventually slay evil spirits and bury the person holding the blade.
