“Chiwu Island and the Conch Pearl” tells the story of Allen Bo and Li Sidi, who take part in in the first Juvenile Detective Competition on behalf of the X Juvenile Detective Agency. They discover clues on the Chiwu Island with several other teams, such as arrows in the messy grass and glycerin dripping down the side of the fish tank. After some deduction, they find that the cook, Uncle Hou, and the team leader, Mr. Du, are all impersonated by Watson's father. The group finally finds the prize of the competition—the conch pearl. In the name of all the teams, the conch pearl is sold for charity and the proceeds are donated to children with leukemia.
