I'd want to take out that beauty person as soon as humanely possible. Obviously after figuring out if the skill will go away after death. Don't need her messing up any other countries. Or going after the niece or something.
But since this manhwa keeps shouting how patriotic it is, I doubt he cares about other countries. This patriotism would make more sense if the battlenet stayed mostly within earth, then after he thought he figured out his end, expand to space. Just seems really weird when the whole earth is in danger and it looks like most of the countries need to pass to do well but he's still here focused on being territorial...
