Ten Kingdoms of Swords and Pens

A modern legal history researcher traveled through the troubled times of the Five Dynasties and became the orphan of a judge who was falsely accused of "collaborating with the enemy" and his family was wiped out. In this martial arts era where "literate people are scarcer than iron armor", he has no system or magical skills, only the ability to solve cases, draw up orders, check accounts, and communicate information. Starting from saving himself with a legal order in the court, step by step from a clerk to being in charge of a government, he uses documents and strategies to "judge" a new order in this troubled world.
