Brother Octopus

The Netherworld Ship followed behind the leading crab, breaking the waves to move forward.

There were mountain ranges under the sea. After crossing those mountains and meandering rocks, they finally saw a beautiful, undersea city. 

It was a real city. Although the buildings weren't really massive, they looked very luxurious. Those structures were glowing radiantly as if they were made of crystal.

The glass buildings looked elegant and stylish, and the towers and pavilions were so dazzling.

Rumble! Rumble! 

As the leading crab landed, a patrol troop of oceanic species' experts swam out. 

The leader of the troop looked like an octopus. That expert had round eyes and a round mouth with some close-knit teeth.

Holding a fine, sharp lance made of some mineral crystal, the octopus leader shouted, "Crab Three! Who followed you here?! You dare bring outsiders to our Gold Shrimp Tribe's territory!"
