Unbelievable!
In their world, the Void Realm can actually be attached to the 'Demon Crystal', and everyone has the opportunity to observe and study it!
Currently, we do not know how they have achieved this, nor whether they can, conversely, use this technology to observe our world. But there is no doubt that these Gray Men have already far surpassed us in material prosperity!
Moreover, the "Divine Envoy" selected by Prince Colin mentioned concepts like "company" and "bank loans", which we had not previously observed. In their world, a "company" is different from our world's mere business unit; it is a social organization that transcends guilds and noble fiefs, possessing absolute power over individuals.
