There was a flashback in the narrative sequence. Reversal was to describe the sequence of events in reverse, and then describe the outcome of the events according to the sequence of events. The advantage of flashback was that it allowed people to understand the process of events more deeply, increasing the attraction and tension of the story. By suppressing the story first and then raising it, the readers would have a deep impression of the characters and events in the story, which would make it easier for the readers to accept and understand. However, flashback narration could also confuse the structure of the story and affect its legibility and comprehension. Therefore, when writing a novel, one needed to carefully use flashback narration to master the narrative rhythm and order so that it did not destroy the overall structure and logic of the story.
