"Sea creatures always avoid us. So what, they don't bother us, and we don't bother them. It's beneficial," said the king's captain, standing by the ship's side.

Sea creatures were legends that some people believed in and others didn't. According to rumors, they were not much different from people on land, except for their bodies. Each sea creature had a similar structure to humans, but they also had their own unique features, depending on the type of marine animal they were related to, such as oysters, jellyfish, fish, eels, deep-sea creatures, crabs, and others. Each creature had its own unique body.

Shadow Milk himself believed in the existence of the sea people, but he had never met them in person. According to legend, there had been a long-standing feud between the sea people and the land people, as the land people had driven the sea people into the depths of the ocean, forcing them to hide there, as the sea people had great power that could create storms and churn the oceans. However, it seemed that this time he had found his fortune.
