Theos' Plan number two: Conquer a kingdom! He wanted his army any way he could.
'For now, let's go slowly, I need to get an Independent Zone, without having to rely on a duke or something' he thought.
Theos turned his attention to the two half-elves, Elsa and Elena. The two had taken an interest in him, though they hadn't called him, he could speculate from the information in the novel that they are rather shy about it, at least they wouldn't call him as soon as they got his number, but would wait a week to call him.
And why did Theos turn his attention to them? Simple, they were half-elves, they could take him to the realm of the Elves to take a Zone there.
That's what Theos had been thinking about for some time, but now that he thought about it more carefully... 'Let's better go somewhere else alone'.
