A thick blue beam of light burst out from the temple, and the ocean began to boil. Blue light from all directions surged from the sea, converging into a massive mermaid phantom wearing a gorgeous crown. Its face was indiscernible, and with every movement, it could manipulate the essence of the seawater in the ocean.
This deity definitely possessed the powerful Ocean Divine Position, otherwise it couldn't possibly contend with a demigod just through an incarnation.
Although a high-level demigod was indeed stronger than a normal demigod, it was still unlikely that one could fight a normal demigod solely with an incarnation. Only such high-level demigods who owned a powerful divine position could achieve this in the short term, relying on the temple and home ground advantage.
