Jon transmigrated to Tremont and nearly died in a human experiment. Fortunately, he awakened a System thanks to the misfortune, one that let him unlock abilities by completing mercenary jobs. After being rescued, he became a mercenary for the Melander Foundation, while also gathering clues to find the evil scientists who had set him up.
But being a mercenary here meant no fame or glory, just working for the capitalists. One false move and they'd devour you, skin and bones. Fortunately, Jon knew the score. Starting from the bottom with nothing? Then he'd build up a reputation, monopolize the arms trade, raise a force, and grow it into something powerful! If his team couldn't win? Then he'd take the field himself. The Federal Army, the Department of Defense, the nations of Terra, the nobility and the powerful... Starting in Tremont, he'd carve a path of destruction across Terra and knock the teeth out of every lofty oppressor!
Years later, when Jon had become a warlord who struck fear across Terra, he sometimes missed the pure days when he took jobs himself.
"Got a hacker job?"
"Can you take it?"
"Sure. Send me the address."
"I've sent you the IP and MAC addresses..."
"I mean the address of the other side's network department."
