Flain, after some thought, devised a plan. He would work on creating a spell, and when he could no longer endure it, he would train for an hour before returning to spellcrafting. This cycle would repeat. For now, this was manageable, as he could only last a few minutes in the dimension where spells were created. However, once he could endure more than an hour, he would adjust his schedule to one hour of spell creation and one hour of training in a continuous loop.
The reason Flain didn't want to go hunt monsters was that he preferred a safer way to farm EXP. He had no reason to rush—after all, he was immortal. Yet, his thirst for vengeance still burned within him and would never cease. Those he wanted dead were already dying, slowly but surely.
For Itai, his task was to generate money. Flain came up with the idea of making Itai an adventurer who would hunt monsters alongside his second-stage undead, concealed in armor so that no one would recognize them.
