At the westernmost point, there was a gigantic harbor where a deep-sea vessel blared its sharp whistle, setting off towards the deep-sea area to fish.
In this world, marine biological creatures could survive in illuminated zones, and massive amounts of algae also bred there. Marine creatures often grew incredibly large, commonly seeing a type of giant octopus named "Antima," each weighing several hundred tons.
These marine creatures provided Giant Stone City with precious food and fish oil. However, capturing these giant octopuses involved significant risk, whether it was from the turbulent sea itself or the marine animals. Previously, before the advent of giant steel wheels, Humans couldn't capture such enormous creatures.
There were also some slave traders at the docks nearby, selling slaves from unknown origins. Shackled men and women expressionlessly disembarked from ships as if they had accepted their fate.
