A magic trick
Not gonna lie, but I think the goddess was just as impressed as the people that stood around me. Her reason though, is different compared to those around me. Hers was genuine surprise at my pronunciation skills, while the ones around me were looks of amazement.
Both looked like magic tricks, nevertheless. I was able to speak an unknown and weird language fluently, which of course, was possible because I was basically communicating with her. By communicating with her, my language compatibility skill was able to activate. Yes, it was that simple, and that overpowered…
Also, the reason why my presentation was also like a magic trick to the people around me. Well… After I had uttered those Chaotic words of the goddess, the Chaos energy went straight towards the device, and the device became fully functional right after.
