Once the novel was finished, the author could stop updating it. But writing a novel wasn't just about writing. It also required editing, deleting, and polishing. This work may require a lot of time and energy from the author, but if it is not completed, the author will not be able to show the reader what they want to express. In addition, the completion of the novel did not mean that all the plots and characters had been fully conceived and designed. Sometimes, the author might come up with some plot or character in the process of writing. These plots or characters might also have an impact on the structure and theme of the novel. Therefore, even if the author completed the main body of the novel, he still needed to make changes and supplements to ensure the logic and cohesiveness of the novel as a whole.
