I, the Mutant, Was Devoured into an Eight-Star Demon King

I was electrocuted and I was reincarnated as the only [genetic mutant] in another world. The game starts with a puddle of water and a dragon beside it. Devouring the genes of all things, evolving into endless forms. Build a demon kingdom, collect all tribes, establish laws, and kill the demon king. When demon kings from all directions are hunting my country, I reveal my trump card: "There is more than one dragon in my gene pool." This world will eventually crawl under my genetic sequence.
