As a fan of online literature, I can't judge which version of The Return of the Condor Heroes respects the original work the most. However, according to what I know, many web novelists will try their best to respect their original works and make certain adjustments and innovation based on them. In some cases, the degree of adaptation may vary depending on the author's background, literary style, reader group, and other factors. However, in general, the editor would try to retain the spirit and core content of the original work as much as possible and make appropriate adjustments and expansion on this basis. Therefore, if one wanted to choose a version that respected the original work the most, it was best to choose a new version that had been carefully adapted and processed, such as some well-known online novels such as The Legend of the Condor Heroes and The Eight Dragons. During the adaptation process, these works paid great attention to the spirit and core of the original work and restored the plot and characters of the novel as much as possible.
