Conan and his primary school classmates went to the library to borrow books that day. It is said that the librarian is missing. As a result, I accidentally turned to some books, and the administrator immediately stopped them from turning to them. They were overloaded when they got off the elevator. At first, they thought it was because the little fat man was too fat. Later, they went to see those books and found that they were hollow and contained drugs. They were found, but at last, they passed the librarian. Conan speculated that there was a body on the top of the elevator, and it was because the curator found out that the librarian used the library to smuggle drugs.
=v= I hope I can help you!
