"Wizard Merlin, be careful not to get too close to the monument. We call this stone tablet the Illusion Monument. If you get too close, you'll be affected by the illusion. Titus had a specific direction of understanding Mind Power. He believed that for Mind Power Masters to understand the Essence, they must first familiarize themselves with Hallucinating spells, cultivating them to their peak!"
After hearing Eldo's explanation, Merlin felt a surge of excitement deep within him. His previous first step in perfecting the system of Mind Power was aligned with Titus' reasoning.
Namely, to first focus on illusory before material. One must cultivate Hallucinating spell to its peak before one could begin to turn illusions into reality! It was just that Merlin had merely taken the first step whereas Titus had already gone on further ahead.
