Cultivation was a fictional world. In novels and anime, it was often depicted as a story of obtaining extraordinary abilities through cultivation. However, there was no scientific evidence to prove or deny the existence of the cultivation world. The cultivation process in cultivation novels usually involved internal energy, external energy, pills, formations, and many other aspects. These concepts did not exist in real life. For example, it was often mentioned in novels that cultivators needed to cultivate internal strength. What exactly was internal strength? Is there a specific method or theory to practice internal energy? There was still no definite answer to these questions. Magical creatures and magic often appeared in the cultivation world, but they did not exist in reality. For example, it is often mentioned in novels that cultivators can communicate with animals and plants to obtain their help, but do animals and plants really have this ability? Was there a specific animal or plant that could be considered a representative of the cultivation world? These questions needed further discussion. To sum up, cultivation is a fictional worldview that is very popular in novels but does not exist in reality.
