Karte World.
In the southern territory of the Giant Demon Empire, about a thousand kilometers from Copper Hammer City.
Here lay the mid-sized coastal Giant Demon City, Phantom Sea City.
Here, vast numbers of human slaves labored in the fields throughout the region.
They cultivated all the grains, medicinal plants, and other crops the Giant Demons required.
Similarly, in the large Airship manufacturing workshops and the shipbuilding ports, the number of human slaves was staggering.
In this world, the Giant Demons were akin to the Celestial Dragon People.
All the heavy, exhausting, and low-skill labor was almost exclusively handled by human slaves.
The main city of Phantom City itself covered about fifty square kilometers, but the territory it ruled exceeded thirty thousand square kilometers.
The Giant Demon population here was approximately three hundred thousand.
But the number of human slaves exceeded one million.
