I Was a Widower in the Northern Song Dynasty

Lu Zhao, a modern surgeon, opened his eyes and became a 19-year-old lowly slave apprentice during the Xining period of the Northern Song Dynasty. He was a lowly person, young, and anyone in the yamen would dare to step on him. On the first day of work: A prison guard died in the county jail, and his superiors forced him to sign a "death from illness" certificate. He could see at a glance: the person was tortured to death. The signature of the petition can be verified as a guarantee - if the case is over, the person to blame will be the signature. If he didn't sign, he would be put on death row and beheaded after seven days. No one listens to his grievances, and there is only one last thing left in the hands of the death row prisoner: a retrial with a different officer, and the original trial officer recuses himself. Only the death row prisoner himself can call for a review process. In front of a room full of officials, he reversed the case for himself from a tampered examination document. They thought he was young and could be bullied, but in fact he was older than all the nobles in the house. Later, when even different examinations no longer worked, he decided to build a machine to make it difficult for lies - a set of inspection procedures that would make it impossible to falsify the testimonials and make it impossible for unjust cases to hide.
