That was when he encountered the “Unlimited System.” This mysterious system didn’t merely make Ethan wealthy—it granted him unimaginable riches and set him on a path that was both exhilarating and perilous. The catch? Each mission the system assigns doesn’t just test his wit and resolve; it also unlocks incredible powers, elevating him to new heights of strength and influence. But this isn’t just a tale of lavish spending and indulgence—though those moments certainly add flavor!
