Fantasy and sci-fi were two different types of literature. The main difference lay in their cultural background and settings. Fantasy novels usually take place in a fictional fantasy world with mysterious forces, strange creatures, elements of myths and legends, etc. In fantasy novels, the protagonist usually gained strength through cultivation, combat, and other methods to constantly explore the secrets of this world. Fantasy novels often emphasized personal growth and experiences, and often included emotional elements such as love and friendship. Science fiction was usually based on science to explore the future, technology, and the fate of mankind. In science fiction novels, the protagonist would usually use technology to solve various problems and explore the potential and possibilities of human beings. Science fiction novels often emphasized the advancement of science and technology and the prediction of the future. Aliens and other elements often appeared. Although fantasy and science fiction both involved fictional worldviews and technological settings, their creative methods and topics were very different.
