The method of transmigration in time-travel novels usually became an important element of the story because different ways of transmigration would lead to different experiences of the characters, resulting in different plots and endings. A common way to travel was through time travel, which was to go back to the past through some special device or method. This method was often used to explore history, change historical events, or shape characters. For example, in " Return to the Ming Dynasty as a Prince," Wang Zhen used a time machine to return to the Ming Dynasty and changed the political situation at that time, becoming a famous official. Another way to travel was through space travel, which was to travel to another world or space through some special device or method. This method was often used to explore other worlds or parallel universes to create new storylines and characters. For example, Wei WuXian in "The Founder of the Demonic Way" entered a different world through transmigration, befriended various characters, and became a legendary figure. The choice of time travel often had an important impact on the plot of the story, so the author usually spent a certain amount of time introducing the time travel method and setting up a background story for the characters who traveled through time.
