There were a few points to note when writing an outline for a long time-travel novel: 1.

This information helps to construct a world with depth and background, making it easier for readers to immerse themselves in the story. 2. Decide on the main plot and conflicts: In the outline, you need to clearly list the main plot and conflicts, such as which era the protagonist traveled to, which characters and events he met, and how these events affected the protagonist's fate and growth. 3. Decide on character development and clues: In the outline, you need to set a clear goal and clues for each character. For example, what is the protagonist's goal? What people and events will he encounter? How will these people and events affect the protagonist's fate? And how will the protagonist develop and grow in each event? 4.
