Water World and Dark Hell

Water World.

A plane filled with water.

Oceans occupied 98% of its surface, with only a scattering of small islands serving as land.

Because the sea covered the vast majority of it, it was called the "Water World."

And because of its abundance of water, the plane was suffused with Water Power, making it highly suitable for cultivating water-element Cultivation Methods.

The intelligent race ruling this plane was also a kind of "Merfolk Race," with gills on either side of their ears and legs that had degenerated into fish fins.

However, this twenty-year-old man named Gang Sanwa was not a member of the Merfolk Race, but a human who lived on one of the land islands.

Gang Sanwa held a relatively high status within his clan. He was the tribal chief's son, and because he was the third-born, everyone called him Sanwa.

Yet even as the chief's noble son, Gang Sanwa had never received any special treatment. Instead, he was often half-starved, poorly clothed, and unable to eat his fill.

It was not that the clan's output was insufficient. The island's resources were fairly abundant, and with their half-hunting, half-farming way of life and Bronze Age level of technology, feeding the entire clan was more than possible.

Not to mention the endless fish in the sea surrounding the island.

But...

The fish in the sea were forbidden to be caught.

Not a single one was allowed to be caught.

On the contrary, every year they had to prepare vast amounts of food as sacrifices for the "God Race" in the sea, using over half the clan's food output to keep the gods satisfied.

A tribe with insufficient food and widespread malnutrition naturally could not develop.

Whenever the weather turned bad and a severe famine struck, it became a harsh trial
