Tae Yi-hyun, known as the Lightning Emperor, was humanity's strongest hunter—a living legend. One day, without warning, he left it all behind to chase an entirely different dream: becoming a web novel author. But there was a problem. Having spent his entire life as an overpowered monster, his writing lacked one crucial thing—realism. Editors criticized his work, pointing out that his stories felt too disconnected from reality. Determined to fix this, Yi-hyun took drastic action. He disguised himself as an F-rank hunter and infiltrated a struggling C-rank guild, Gahwa Mansaseong. At first, it was just for research—gathering material for his novel. But before he knew it... "Wait... I actually like this guild?" As he observes the brutal struggles of low-ranked hunters, Yi-hyun begins to grow—not just as a writer, but as a human being. Once hailed as a god, can this former legend find success as a mere writer? (Source: Kakao Entertainment Corp., translated)
