A Comic Artist’s Survival Guide

A Comic Artist’s Survival Guide summary:

Snow, a failing comic artist whose comic is about to be discontinued, reincarnates into his own comic by chance. In his comic, the Pante Continent is on the verge of ruin due to the expansion of the Demon King's army, resulting in Snow being in danger as well. Just as his life was about to end, Snow receives an opportunity to survive, with the condition that he takes over the author's role and rewrites the entire comic's storyline. If he fails to " create" a more interesting story, then Snow and the comic world would be destroyed
