Rebirth novels and time-travel novels were two common types of web novels. They had some similarities, such as the story of time-travel and characters traveling to the past or future. However, the essential difference between rebirth novels and transmigration novels was: The protagonist of a rebirth story usually went back to the past or the future to start his life again. The protagonist of a rebirth story usually did not experience death but was reborn into this world at an unexpected moment. The plot of a rebirth story often revolved around how the protagonist used the opportunity of rebirth to change his fate and the course of history. The protagonist of a time-travel story usually traveled to a certain point in time in the past or future at an unexpected moment to become a personal experience of a certain character or event. The protagonists of time-travel novels usually had some special ability or background. They changed the course of history and the image of the characters through time-travel. The storyline of time-travel novels often revolved around how the protagonist used his special abilities and background to change history and character images. Rebirth novels and time-travel novels were quite different in terms of storyline and character setting, but both involved time-travel and characters traveling to the past or future.
