Ilyon town is not actually the closest place to the initial border between the devil territory and the Doria Empire. There is another place the devils have already passed through to reach Ilyon. the fortress town of Falanis. This town, which fell under devil control after being attacked several times during the initial phase of the invasion, has become their new buffer zone before orthodox cultivators can reach the devil territory.
Before the invasion, people could clearly see the devil territory from this town, as the sky above the devil territory was blood-red and ominous, even from a distance. However, since the devils took control of this place, the red sky has started to move, and now part of it hovers directly above the town. The ominous atmosphere has also grown so intense that mortals without any cultivation risk being driven insane just by staying there.
