“Even with a trash job Alchemist, I can still go full OP—because this is the game world I mastered in my previous life!” Yuren is the eldest son of a prestigious family, expected by everyone to become the strongest. But instead of choosing powerful jobs like Sword Saint , he deliberately picks the notoriously weak Alchemist. In truth, Yuren’s previous life was that of a modern guy who played this very world as a game and completely mastered it. He’s bored of becoming strong in the normal way. This time, he wants to enjoy a self-imposed challenge run: starting at low level with a weak job and still dominating. His choice infuriates his father so much that Yuren is kicked out of the house, and thus begins his journey—a travel adventure built around his “perverted” playstyle, using game knowledge and the “worst” job to break the world and overpower everything from level 1.
