The Strongest Physical Exorcist

In a world overrun by demons, someone who can't cultivate exorcism arts has only one option: keep improving their physical strength.

And so, an overwhelmingly powerful physical exorcist was born.

Wondering why the protagonist is so strong? Just do ten thousand weighted push-ups, ten thousand weighted squats, and ten thousand hanging leg raises every day. (Don't try it, unless you want rhabdomyolysis.)
