The main difference between the online version of Dragon Clan 3 and the physical version was due to copyright issues. There were differences in copyright between the online version and the physical book, which led to the difference in content. The content of the physical book version was edited and proofread by the publishing house. Usually, it would be arranged and modified according to the original story plot and structure. On the other hand, the author was responsible for editing and proofreading the online version. He could modify and adjust the storyline and characters according to his own ideas, and he could add and delete content more freely. Due to copyright issues, there might be some differences in content between the online version and the physical version. For example, some scenes, characters, and dialogue in the physical book might not be able to be used in the online version because of copyright issues. In addition, there might be some differences in printing and cover between the online version and the physical version. It was normal for the content of the online version to be different from the physical version. Due to copyright restrictions, authors could only create according to their own ideas and might not be able to completely restore the original plot and structure.
