Genshin Impact: The God Who Rules the Seas

[Multiple Original Content] [Demon God War] [Female Lead: First Water Goddess: Ergolia] (The Demon God War storyline continues into Volume 2; Volume 3 is slice-of-life content)

Su Nan, who died suddenly in bed after taking a nap, transmigrated into an elemental fish during the Eternal Continent era of Genshin Impact. During this time, he witnessed the continent being torn apart, the sea turning into mountains, and irreparable cracks appearing in the sky...

In order to survive, he chose to become powerful, powerful enough to rule all the seas!

"I, Aulias, declare to this world, that I... rule over all the seas!"

…………

The novel's plot begins 4000 years before the main storyline, a period before all the disasters and regrets occurred... even the Demon God War hadn't truly begun, so there's a lot of room for manipulation and original content.
