The difference between the old and new versions of the novel usually lay in the content, including the plot, character setting, background story, and so on. Some authors might make changes or add or delete to their novels to reflect their creative ideas or to meet the needs of readers. In addition, the new and old versions of the novel may also have differences in writing style, language style, and details. Some authors might tweak the words, sentences, and expressions of their novels to suit the tastes of modern readers. When buying a novel, it is recommended to compare different versions of the novel to understand their differences in order to better enjoy reading. At the same time, you can also consider buying adapted novels such as movies, TV series, or games to better understand the storyline and character settings.
