Shadow on the Moon

Anyone who could construct a stable Spell Model could become a Wizard — that was the Wizards' ultimate secret! Having been given a new life as the son of an aristocrat and armed with a super quantum computer from his past life, Spell Models game as easily as breathing to Merlin. With this overwhelmingly huge advantage, would Merlin become the greatest Grand Wizard of all time?

"The Mind Heart can still be compressed?"

Merlin was stunned. Currently, his Mind Heart was almost at its limits and could no longer be compressed. If Merlin was able to further compress the Mind Heart, then his Mind Power would undergo a substantive enhancement. Perhaps his Seventh-level Mind Heart would be able to rival an average Ninth-level Spell Caster's Mind Power.

"That's right. Occult Mind Spells have a very high requirement for Mind Power. This is similar to the requirements of Spell Models for Spell Casters. The stronger the Mind Power, the more powerful the Occult Mind Spell that is released! Therefore, compressing the Mind Heart to accumulate more Mind Power is one of the persistent goals for Mind Power Masters. As for me, I've invented an excellent Occult Mind Spell that can compress the Mind Heart to extreme limits!"
