I've Somehow Gotten Stronger When I Improved My Farm-Related Skills.

Al Wayne loves farming — and we don’t mean the video game sim. He wants to be a literal farmer, but in the process of improving his agriculture skills, he somehow winds up maxing out his overall character stats! He’s superpowered in the most unexpected of ways with abilities even the strongest of heroes would envy. Alas, all he wants is an idyllic farmer's life, but with demons and monsters invading the realm, Al may have to take up the mantle of hero just to keep his dreams from withering away!
