One Swing Man [An OP MC Isekai LitRPG]

When you're the strongest, you run life on easy mode.

Greg was an ordinary office worker with a penchant for daydreaming when he was sucked into the bowels of Hell. Forced to slaughter to survive, with nothing but a club, he steadily advanced while getting stronger. After killing the current King of Hell, he is transported to the fantasy world of Dalador. A world of Classes, Mana, and Guilds. A fantasy world of dragons and mages,

First thing Greg does? Kiss the green ground, and jump for joy. He'll finally be able to relax.

Of course, fate has other plans.
