The Strongest Rampage Cheat System

Others are controlled by their Systems, but Fan Lang controls his System. Think leveling up is too slow? Set experience gains to triple! Think your attack power is too low?

And so begins a wild rampage of total domination, a journey with no upper limit and no lower limit...
