Marz World, a world with a highly developed civilization.
The civilization living within it already possesses the ability to transform the world through its own technology.
Bridges spanning the sky and earth connect every city in this world.
Towering steel skyscrapers are everywhere, and giant energy pipelines run through every corner of the world.
Blue skies, white clouds, green mountains, and lush grass...
These natural landscapes, almost neglected in the Mountain and Sea Realm, here become spectacles that only a few high-ranking officials can enjoy.
Upon gazing ahead, the polluted and radioactive elemental black clouds dominate the sky.
Still, these do not affect the civilization living in this world.
Because the race that constitutes the main body of this civilization originally lived underground, the Burrowing Insects.
