The next morning, the captain asks the coroner if the body has been checked. The coroner has not yet checked the body, but the captain says that he has already taken precautions to protect the crime scene. The captain asks if the name of the pawn shop that the captain worked with sounds familiar. The pawn shop is called the "joy" pawn shop, and the captain is shocked to learn that the shop has been in the city for two decades. He asks the captain to investigate the shop immediately. He says that the business of the shop is moderate, but its scale is not conspicuous. He also says that it has only been in existence for 20 years, and that it is like a "sholdage distribution map" of the family after the fall of the former dynasties. He wonders if they may find clues about his mother. The murderer behind the fourth lady's killing brought the captain here to investigate this case, and he will stay with the captain from now on.
