In novels, bloodline was often used to describe the lineage and inheritance of a family or race. Bloodline levels were usually exaggerated and fictional settings used to enhance the plot and character settings of novels. In some novels, the power and potential of bloodlines could be divided into different levels, such as ability, talent, or the length of time the family had passed down. There were also some novels that might divide bloodlines into different types, such as orthodox bloodlines, evil bloodlines, mutated bloodlines, etc., to create different characters and plots. Bloodline levels were usually set according to the needs of the novel and the author's imagination. There was no need to pay too much attention to it.
