Generally speaking, writing 10,000 words per chapter was quite common. This depended on the length and theme of the novel, as well as the author's writing style and speed. For some short stories, 10,000 words might be enough. For some novels, such as " Battle Through the Heavens " or " Ghost Blows Out the Light," a chapter might require at least 20,000 words. The length and theme of the writing would also lead to a difference in the amount of 10,000 words written in a chapter. But in any case, he should maintain a reasonable writing rhythm to ensure the quality and legibility of the novel.
