Along the way, Merlin kept asking about training drills in a roundabout matter. However, Mia and Kevin were not very clear about the higher-class of this world.
They only knew that the strongest beings in this world were Sanctuary Contenders. They had never seen a Sanctuary Contender before, so they naturally could not tell the difference.
Merlin contemplated carefully. How far would he reach by relying on the training drill? If it was just to Great Legend, then it would not be very remarkable. Merlin was no longer a mere first or second-level Spell Caster. His worldview had widened a lot since then. He had even seen Ultimate Arcane Wizards.
The Spell Caster system, Mind Power system, and this training drill system all had different emphases and advantages. Relatively speaking, the Spell Caster system was the most perfect, and the Mind Power system had the most potential.
