The reason why online novels became online games was that online novels usually used fictional worlds and characters as the theme, while online games were multiplayer online games based on these fictional worlds and characters through computer programs. There is a close relationship between online novels and online games because many plots and characters in online novels can be adapted into characters and game mechanisms in online games to attract more readers and players. For example, in the online novel 'Battle Through the Skies' the protagonist Xiao Yan could be adapted into a game character in an online game. His battle skills and growth process could be displayed in the game. Similarly, Hu Bayi from the online novel Ghost Blows Out the Light could also be adapted into a character in an online game. His adventure experience and combat skills could be reflected in the game. The interaction between online novels and online games made the story plots and characters of online novels more rich and interesting, and also brought more entertainment and experience to readers and players.
