Strange Cases in the Late Qing Dynasty 2

In the autumn of the ninth year of Tongzhi, a secret letter written in blood was found on the waist of a floating corpse at Jinmen Pier. As soon as the imperial envoy got off the sedan, his throat was blocked by a dart thrown in the dark. The tail of the dart was engraved with a small word "Cao". I was ordered to conduct a secret investigation, but found that the thirty-eight corpses pointed to a terrifying Cao Gang legend. The helmsman sneered: "The word "official" is not as happy as us 'walking the path of heaven'." The night I visited the Dragon King Temple, I heard the coughing of the old gang leader who should have been dead for many years.
