An undeleted version of a novel usually refers to a version of a novel that has been edited and modified before it is published. It may contain some deleted or modified content. This type of edition is often called a 'revised edition',' modified edition', or 'uncensored edition', because it indicates that the novel has been edited and modified before it was published. Unlike movies and television, novels were usually not published in an unedited version because editing and deleting content could lead to a decline in the quality of the novel and affect the reader's experience. On the contrary, novels were usually published in multiple versions, each of which contained different editing and modification content to meet the needs of different readers. Some novels would be edited and revised after release to further improve the language and plot.
