In the carriage, Merlin observed the two Spell Models within his Awareness.
The Magic Power accumulated by the Spell Model of the Fireball was already very deep and rich. Merlin made a rough estimation that he could unleash approximately twenty-five normal Fireballs.
Such a Magic Power was already immensely rich and thick. Old man Etha's Spell Manual had mentioned that a typical Spell Caster would only have just enough Magic Power to unleash thirty spells, after accumulating it for a long time. By now, though, Merlin had only been constructing his Spell Models for two or three months, but he was already coming close to achieving an accumulation that a typical Spell Caster would need several years to attain.
