There exists a distinct demarcation between the Natural Federation and the Curse Demon Empire.
Along this line, the army from the Natural Federation has turned almost every world into a fortress world.
The war fortresses of the Tree Spirit Clan and the Mechanical Clan resemble monsters perched on the plains, with vast rivers flowing between the fortresses, each filled with sea beasts nurtured by the Tide Spirits.
On the other side of the line lies the world of the Curse Demon Empire.
The Curse Demon Empire has long been the aggressor, so their world lacks fortresses. There's only the slave army with bloodthirsty teeth and ceaseless slave factories.
Richard crossed this line, but he didn't directly contact the Curse Demons. Instead, in an extremely concealed manner, he silently observed the world of the Curse Demons.
