"What the hell? What did you do in the past few weeks? Did you not come home because you were robbing those countries?" Maya was stupefied. On the one hand, the countries were empty after the apocalypse, so robbing them wouldn't be an issue. On the other hand, there were so many strong monsters, including World Class Monsters. So, going there was not necessarily the best idea.
So, she didn't know how Theo could do all of that in the span of a few weeks. Even if he managed to kill all the monsters in his way, he had done the work of a thousand people by himself.
She didn't know that Theo had an army of monsters, led by a World Class Monster, to ransack all that was left in those countries.
Still, no matter how he did it, there was one thing that remained. With all these materials Theo got from many countries, he could be said to be the richest man in the world. And it wouldn't be hard for him to get the buyer for those materials.
