Kapitel 1833: The Deliberately-Caused Sea Hazard!

When Lin Yuan was learning about mermaids and major sea demons, he read through many secret tomes.

According to the historical records, there were only three kinds of lifeforms in the world of human-shaped lifeforms with fishtails.

One of them was deep-sea mermaids. Lin Yuan already knew that they came from the water world and had accidentally arrived in the main world and managed to breed.

The second group was the sea demons that came from the Lantis Mystic Realm, and the Azure Federation regarded them as strategic-class resources.

The deep-sea mermaids were already considered legends. Yet, the third group of lifeforms was even rarer than deep-sea mermaids.

This type of lifeform was not born with human form. Rather, they had to continuously absorb vitality from humans in order to transform themselves into human form.
