As a fan of online literature, I don't have any subjective opinions. However, from the reactions of some readers, there were a few reasons why novels with paladins as the main characters might not be very popular: The religious element may make some readers uncomfortable: the paladin is a character with faith and justice as the theme, and the religious element may be seen as too serious and heavy in some readers 'hearts. Therefore, if the main character of the novel was a paladin, it might make some readers feel uncomfortable if it contained too many religious elements. Battle scenes can be too bloody: Paladins are usually portrayed as powerful warriors who need to fight fiercely to protect faith and justice. However, these battle scenes may make readers feel that blood and cruelty may not suit the taste of all readers. 3. The story may not be attractive enough: If the protagonist is a Paladin, the novel may not attract enough readers if it lacks an attractive plot and storyline. In comparison, other types of novels such as fantasy and science fiction might be more popular. Of course, this was only the reaction and opinion of some readers and might not apply to everyone. Different readers have different preferences and tastes, so it is very important to choose a novel that suits you.
