I'm just a person who likes reading novels, so I can't provide any information about the specific works. However, generally speaking, the quality of a work's reputation was affected by a combination of factors, including the storyline, character creation, picture quality, music and sound effects, and so on. Perhaps there were many reasons for Yuan Long's work's decline in reputation, such as problems with the storyline, insufficient character creation, poor image quality, poor music and sound effects, and so on. Only by knowing the specific situation could he give a more accurate answer.
