The plot and emotional lines of web novels were important elements. Different readers might have different preferences for them. However, generally speaking, the plot line of a web novel was more important. The plot line refers to the main plot and main conflict of the novel. It is the core of the novel and determines the theme and structure of the novel. A good plot line could attract the reader's attention and make the novel more attractive and readable. The emotional line referred to the emotional entanglements and relationships between the characters in the novel. It could make the novel more vivid and touching, but it was not necessarily more important than the plot line. In some novels, the emotional line might become an auxiliary to the plot line or just exist as the background of the story. However, whether it was the plot line or the emotional line, web novels should pay attention to quality. They should not blindly pursue quantity and ignore the quality of literature. In the process of writing, the author should pay attention to the logic, cohesiveness and rationality of the story, try to avoid the plot like a running account, and at the same time pay attention to the character description and emotional expression so that the readers can deeply feel the meaning and meaning of the novel.
