A modern young man wakes up to find that his soul has transmigrated into Lin Cheng, a constable in Jing County of Great Chu.
The original Lin Cheng had openly defied the county magistrate and landed in prison, leaving him with a complete mess and a motivational System waiting to be activated.
It's a hellish start: locked in an iron cell, while outside the notorious Black Fiend terrorizes the countryside. A string of bloody murders has shaken the whole county. The officials are helpless, and the people live in constant fear.
Wan'er, his childhood companion and child bride, scrimps and saves as she makes connections everywhere, working tirelessly for him outside the prison.
To activate the System, he must first get out of prison!
Lin Cheng abandons the original's stubborn naivete and stakes everything on the Black Fiend case to carve out a way to survive.
Modern criminal-investigation methods go up against a cunning and deranged killer. Lin Cheng painstakingly pieces together the clues, searching for evidence in the smallest details.
From then on, he rises step by step, from a privately hired constable to the chief of the Six Fan Gate.
At first, he only wanted a steady job and to keep the one by his side safe and happy year after year.
But the power to investigate has quietly fallen into his hands. Injustice is rampant, and corrupt officials run wild.
Lin Cheng stands with his blade in hand.
"Since I'm a judicial constable, then I shall discern good from evil, redress wrongful convictions, purge the officials, and wield the authority to execute first and report later!"
