The Kandrian Empire's initial plan in regard to the Serevian Dungeon was simple;
Expand aggressively and fast.
Prevent the closest competitors from expanding.
The former was, of course, to capitalize and colonize as much land and as many resources as possible. The latter was to ensure that none of the Kandrian Empire's closest competitors could colonize land and drain it of resources.
It wasn't good enough to seize land already seized by the competitors of the Kandrian Empire. If the Kandrian Empire seized lands from other nations, those lands will likely have already been completely drained of their fruit. The fruit extraction process was rather easy and quick, after all. Even if the Kandrian Empire invaded and conquered territory only a few days after they had been initially colonized, it was entirely possible that all the fruits will have been entirely plundered by the colonizing group that the Kandrian Empire conquered the land from.
