Although Alister didn't plan to be too hasty in dealing with the problem regarding the otherworld, it was inevitable for him to be wary of the otherworld especially when even an overlord-level monster was enslaved by the world with a higher civilization.
In that Technology World with countless cyborgs, Alister even doubted whether some of those cyborgs were the transcendents who were enslaved by Technology World.
After all, there were already cases when some transcendents invaded the Technology World just to obtain information regarding it. However, none of them had successfully returned.
Alister even doubted whether the three Transcendent Saints of the human race dared to intrude into the Technology World. Even an overlord-level monster was enslaved by the Technology World let alone saint-level humans like them.
