Jason in the Apocalypse [LitRPG, System Apocalypse, Progression]

On a Tuesday morning, the sky turned purple and the world changed. The System arrived, monsters followed, and humanity got seventy-one hours to figure out the rules before Phase Two began. Jason, a brush-clearer from nowhere in particular, found himself staring at blue boxes in the middle of a pine forest with a jammed chainsaw and his brother's boot-stretching feet to blame for his mood. In a world that rewards power, Jason doesn't hit the hardest. He just always knows exactly where to hit.
