Dragons and Demons was a popular wuxia novel in which players could improve their abilities by leveling up, fighting monsters, and forging equipment. Among them, playing books was a common way to improve a player's character's ability. In Demigods and Dragons, players could purchase skill books through the game store or stall. These skill books could be added to the player's character to improve the character's skills and abilities. Different skill books could add different skills. Some skills could increase a character's attack, defense, hit, and other attributes. Some skills could increase a character's defense, dodge, and other attributes. However, the drop rate of the skill book was relatively low, and different classes and different levels of characters could obtain different skill books. Therefore, players needed to do a lot of activities and missions in the game to obtain enough skill books to improve their abilities. In Demigods and Dragons, one needed to pay attention to the use of skill books. Different skill books required different skill combinations to obtain the greatest effect. At the same time, players also had to consider the overall development of their characters. Not only did they have to consider the improvement of skills, but they also had to consider the matching of equipment and the enhancement of attributes.
