Wuxia novels used to be very popular, but after the rise of online novels, wuxia novels gradually declined. There were several reasons for this: 1. Compared to online novels, wuxia novels have a relatively smaller audience. Although online novels were very popular, the readers of martial arts novels were relatively more fixed. They were mainly older readers, and these readers had a clearer preference for online novels. 2. The story and worldview of Wuxia novels were more complicated and required higher literary attainments and imagination. Compared to the relaxed and entertaining style of online novels, martial arts novels tested the reader's reading ability and comprehension ability. The writing of Wuxia novels was more difficult and required more time and energy. Many authors of martial arts novels needed to study history, philosophy, martial arts, and many other fields to write deep and charming works. On the other hand, authors of web novels were more focused on improving the storyline and writing style. The development of online novels made readers more satisfied with the convenience and variety of reading. Online novels could improve reading efficiency and convenience through the platform's automatic typography and automatic recommendations, while martial arts novels required more manual operations. In summary, the main reasons for the decline of martial arts novels were the changes in the audience, the increase in the difficulty of reading, the increase in the difficulty of writing, and the changes in the development of the Internet. Although martial arts novels were not as popular as before, many authors were still working hard to create them, and the readership was also increasing. In the future, martial arts novels might rise again.
