I believe I forgot to add this in the latest chapter~ well, to make it easier for someone that don't know about Indonesia's geography and islands location I will briefly describe you about Ridwan's route of rescue~

A case of theft: this story is not rightfully on Amazon; if you spot it, report the violation.
Let's say that Indonesia is vast, and divided by sea, so it took him trouble to jump here and there as fast as he could, and by no means that he's able to save everyone in ever place.
Well, to make it Brief he only play on the right side of the map... the place where Papua's in is the right one, then he move faster to the nearby Island and then the last place he goes to is Bali which is just beside Surabaya... well, what can I say? a human can't take care of every problem by himself after all...
That's all! well, I can just show you the map and buh-bye but yeah... a little explanation might help you since I believe not many of you do know where Indonesia is on the map... lol
