"Hidden Sacred Beasts At The Headquarters" 

With the ten rare races who followed the Godfather joining the battle, the group quickly left the underground dungeon, and even managed to 'climb' the building to the meeting room where Ainsley and the others were detained. 

The world union made one whole floor to contain these transmigrators, so the security could be targeted into the whole floor. 

When Axelle and the others were rushing to breach the security guards of this floor, with so many other guards and prisoners chasing them from behind, the Godfather finally contacted Ainsley about their successful escape. 

[Lil lass, we are about to enter the floor where the transmigrators are detained. Quickly find a way to create chaos and attract attention so that we can escape.] 

Of course, escaping might not be as easy as what the Godfather said because even if there were windows in all meeting rooms, those windows might be fake windows or traps.
