Hiding a Logistics Center in The Apocalypse - Chapter 40

I don’t like the manhwa that apocalypse happened on earth but on focus only on korea. You understand what i mean , as if there is no other country left than korea. Whatever monsters or whatever gate open only on korea. Look here apocalypse happened and we still know the situation of other countries. Other authors should learn from this.at least do have some sense . Even if apocalypse happened in real, standing only korea except others is only happen when the sun rises form west.
