Captive novels referred to setting up a fictional world or character in a novel so that the author could freely express his creativity in it. This form often appeared in fantasy, science fiction, martial arts, and other types of novels. The purpose of the novel was to provide a broader creative space for the author so that they could explore more plots and character settings to improve the quality and influence of the novel. There were many ways to achieve this. For example, the author could set up a fictional school, city, organization, etc. in the novel and then construct the details of the world according to his own storyline and character settings. It could also allow the characters in the novel to have different backgrounds and personalities to enrich the storyline and character creation. Fiction-rearing could allow readers to better understand and appreciate the novel, and at the same time, it could also provide more inspiration and motivation for the author.
