Generally speaking, a published novel could not simply be published together with an existing novel. This is because the plot, characters, worldviews, and other elements in the novel are all independent. They may conflict or not be suitable for presentation in a new publication. If you want to combine the published novel with the current novel, you need to re-edit and integrate them so that they can coexist harmoniously. This can take a lot of time and effort and requires permission from the editor and the editor. Of course, there were also some editors or editors who were willing to try to combine published novels with current novels, but this usually required sufficient attention and investment. Therefore, if you are considering combining a published novel with an existing novel, you should first consult a professional editor and a bookstore to understand the relevant procedures and requirements.
