Mastery

Illusion, as the name suggested, were fake phenomenons created by spirit energy.

Compared to psychological illusions, projection illusions were much simpler and were also the most common type of illusion.

Even cultivators who did not cultivate illusions usually knew one or two simple projected illusions.

According to the book, one needed to possess a deep spirit energy to cultivate an illusion technique. Otherwise, it was very likely that the spirit energy would be exhausted before the illusion could be condensed.

Although projected illusions were not as lethal as psychological illusions in battle, there were still some exceptions.

For example, in the case where one's opponent's spirit sense was extremely powerful, psychological illusions might very well lose their effect.

On the contrary, projected illusions could deceive the opponent and even disturb their spirit sense. Even if one couldn't win, he or she could still retreat unscathed.
