Ten years ago, the Shen family, who was in charge of the world's tax accounts, was framed as a collaborator with the enemy. Everyone in the family was convicted. Only the youngest son Shen Jinghong survived.
Ten years later, he changed his name to Ji An, was admitted to the Ministry of Household Affairs, and became the lowest level clerk.
He doesn't know martial arts and has no backing. His only strength is that no one in the world knows things better than him.
The scholar who forged letters, the jailer who took bribes to destroy evidence, the colleague who handed over the knife, the criminal officer who finalized the case, the uncle who planned the plot... Everyone who framed his family back then left their handwriting in the pile of old papers.
He doesn't kill people, he keeps accounts. Use the court's own rules and procedures to legally send the enemies to death one by one.
The other party thought until his death that he was killed by the system.
——Accounts must be settled and people must live upright.
