As a fan of online novels, I can't comment on whether Lu Han's Grave Robber's Chronicles is inferior to the other novels. However, I can provide some possible reasons: 1. Plot: Grave Robber's Chronicles is a grave robbing novel. The plot is more complicated and requires the reader to have a certain imagination and reading ability. Therefore, a longer novel might require more time and effort from the readers to understand and appreciate it. 2. Writing quality: Grave Robber's Chronicles 'writing quality is high, but it also requires a certain amount of time and effort to read and understand. As an actor, Lu Han might not have had enough time to write and revise like other authors. 3. Audience: The audience of Grave Robber's Chronicles was mainly young readers, and Lu Han was also a young actor and singer. Therefore, he might not have a wider audience like other authors, nor did he have enough resources and energy to promote and publicize. It should be emphasized that any novel has its value and charm, no matter who wrote it. The most important thing for the readers was to be able to find a novel that they liked and enjoy the story and plot.
