After the Library Closes

[The new book "Operation Double Detective Team" is now online] This book is a fan work of the "Extracurricular Detective Team" series I apologize for some places and characters that I didn't fully understand in the original book. I also want to thank my friends in the Kezhen online communication community for their valuable opinions~ Some original OCs will be added. Most of the characters are from the original books. Some personal settings of characters from the books may also be used. Please forgive me~
