For months, William kept moving from one lower realm to another, sparking a huge rebuilding process, making sure everything went smoothly as he planned.
At some point, he would stop and return to his world to check upon his friends, girls, and guild masters in training. They were all absorbed in training and looked almost like reclusive masters he had seen in his previous lifetime.
The Blue Purgators' way was simple; using the special environment he provided, they taught all the masters one unified and basic training manual. It wasn't that great or remarkable, yet it had a single advantage.
Training on this manual would ensure raising one's spirit power by one grade. It wasn't enough to get someone from one grade to another, but it was with no equal when the spirit master needed to raise his spirit power in one grade.
