Introducción breve: During the Zhengde period of the Ming Dynasty, Ye Guotao, Dong Yunfei's master, was killed while investigating a murder case in Mount Longhu. As Ye's favourite protege, Dong Yunfei was appointed as a detective constable in Department Six, a detective agency in the Ming Dynasty. Dong Yunfei followed the only piece of evidence at the crime scene, a "token fragment", gradually uncovered the hidden conspiracy about the treasure in an ancient tomb behind the murder, and thus put himself in great danger and had himself haunted by several groups of people. Put his safety aside, Dong Yunfei cooperated with the governor's daughter and Detective Constable Fang and investigated this case further and further. They found that someone was using blood-worm poison to murder people for profit, and eventually revealed the truth by forcing the real culprit to come into the light.
