Su Che, a modern law student, transformed into a low-level official in the Qin Dynasty. The original owner offended the powerful because of impartiality in enforcing the law. In order to survive in the Qin Dynasty with strict laws, he could only rely on his half-knowledge of Qin's laws and walk on the edge of a knife. Until one day, he discovered that the files he was dealing with were surprisingly similar to the "Lost Qin Law" discovered by later archaeological discoveries.
