Help find Ben, the protagonist of fantasy novels, and let him be reborn as a creator. His ability is decomposition and combination. He created the gods, and later used the twilight of the gods in their battle.

In My Reborn World, the protagonist is betrayed by Poseidon, and his woman (the dragon god: Kana, Audrey: the goddess of life, Tanya: the earth goddess: Elanis: the elf god created by the protagonist) summons him to kill Poseidon with the dusk of the gods. I don't know if it is what you want.
