The problem of farming books in the game referred to the fact that players could obtain various books such as martial arts manuals, divine artifacts, etc. by completing missions and challenges in the game. These books could be purchased from NPCs or obtained through Dungeon drops or synthesis. The process of farming books required the player to have some skills and strategies because farming books required a certain combination of luck and skills. Players needed to understand that different books required different skills and equipment to support them. They also needed to understand the functions and substitutes of different books. Players also had to choose the right dungeon and challenge to obtain the required books. Different dungeons and challenges dropped different books, and some books could only be dropped in specific situations. In short, reading books was an important part of the game. Players could improve their martial arts and strength by obtaining various books, but they needed to be careful and lucky.
