Huang Silang, who lives in a remote mountain village, has a pure nature and a sharp mind, but due to his livelihood, he always does some sneaky and deceptive activities. But one night, Huang Silang accidentally discovered that someone had hanged himself in front of the ruined temple where he lived, and an identity document was found from the person's body, showing that the deceased was a government servant. Huang Silang felt that this person looked very similar to himself. In order to get rid of the shackles of fate, Huang Silang exchanged clothes with the other person and replaced the identity of the deceased government servant.
But he didn't know that the yamen officer was carrying a case. He had no choice but to commit suicide here because he knew a secret he shouldn't know. Huang Silang had no idea about the province and the past of the yamen servant. After pretending to be the yamen servant, he accidentally solved many cases.
Huang Silang gradually discovered the truth behind the death of the government servant. In order to avoid the fate of being killed, Huang Silang uncovered the truth behind the whole thing step by step and investigated the entire case to the end.
