Rein and Hana hurried as much as they could but still bringing such a large army to a very distant place was very time consuming. So they would need at least two weeks to gather the army in the golden city even if they hurried as much as they could.
As for Sophia she had been scouting the Nest of All Chaos from a distance. She knew that, inside a danger zone, the will of that danger zone was able to observe anything perfectly. So no matter what Sophia did, she would not be able to hide herself from the will of All Chaos. That was why she was not getting close to the borders of the danger zones at all and keeping an eye on it from a distance.
But even doing this was dangerous. As the insects of this danger zone were able to come out of the borders, these insects regularly patrolled the area outside the border. So Sophia needed to hide her presence in this area too.
