As a fan of online literature, I can't judge whether a book is good or not because everyone's preferences and tastes are different. However, based on my knowledge of online novels and the feedback from readers, the Dragon series is a very popular novel series. Many readers like every one of them. It was also a subjective question as to which one was better because everyone had different opinions on the plot, characters, and theme of the novel. Some people might prefer the first Dragon Clan to the second Dragon Clan II, and some people might prefer the second Dragon Clan II: Dark Dragon Clan to the third Dragon Clan III: Eternal Dragon Sky. Finally, I want to emphasize that no matter which book you choose, you should choose it according to your own interests and preferences, not be influenced by the opinions of others.
