Reincarnated By The Weakest Primordial Being(but with OP growth twist)

AK was never meant to be the protagonist. In the original story of this world—written by RED, the greatest light novel author—AK was just another hunter doomed to die. But when RED is mysteriously summoned into his own novel as the Strongest Primordial Being, he makes a decision that changes everything: He chooses AK as the new hero, rewriting fate itself. Now, armed with his future memories, a dangerous OP growth system, and RED’s hidden guidance, AK must survive deadly dungeons, battle gods,demon king, angel's, and rise above the chaos of a collapsing world. But the story has already changed—and even RED doesn’t know how it will end.
