Isekai ni Houchi Game Riron wo Mochikondara Sekai Saikyou ni Nareru Setsu

Isekai × Idle Game = The Strongest!? Idle games—a system designed for the busy modern world that lets you grow stronger quickly with minimal effort, often while you’re away from the game entirely. After an ordinary middle-aged man is reincarnated into a fantasy world, a sudden thought strikes him: “If I apply idle game mechanics in another world… wouldn’t I become the strongest?” But can the logic of idle games—passive growth, automation, exponential scaling, and offline progression—really work in a living, breathing fantasy world!? To reach absolute power with minimal active effort, he sets out to establish an idle-game system in this new world!
