Empty lines refer to fictional characters, places, things, and other non-existent meanings that appear in novels. They are usually used to construct plots and create characters. Space-time travel was a common technique in writing novels to allow readers to better understand the plot and characters to increase the reading experience. There are a few points to note when using blank lines: The blank line should appear alone and should not be used with other words. The length of the blank lines should be appropriate, not too long or too short. The positions of the three empty rows should be reasonable, not too dense or too sparse. The use of four blank lines should be in line with the overall style and atmosphere of the novel. By paying attention to the above points, you can reasonably use blank lines to increase the legibility and interest of the novel.
