When Melina and I returned to the Bao's mansion, the lady wondered why we were back so quickly, as she expected us to take a bit longer.
Of course, she couldn't see that we were holding two invisible people with us, but their potions only had a few minutes left before the effect ran out, so we asked her to come with us.
The Bao's mansion didn't have a dungeon since they didn't think it was necessary, which was nice of them, but having one at that moment would have been quite helpful.
To keep the kidnapped nobles away from the eyes of the servants, we went to our room, where we had the trapdoor to the underground room with the magic quartz, and used earth magic to make it a bit wider.
When we dropped the invisible nobles on the ground, Lady Bao asked what it was, but we just told her to wait a few seconds as the potion's effect was just about to end.
