Two choices.

"Lady Faustina, please leave, I wish to talk to my disciple, alone." 

"Huh? Why? What happened? Didn't he just break through? Then why does he look so devastated?" 

Faustina questioned with a confused look on her face. 

Since Nux knew that Aeliana had sealed the area, in order to focus on his breakthrough, he stopped using *Essence* to hide his presence, so right now, even without Faustina's help, Aeliana could see everything and because of this, the moment she saw the change in Nux's expression, she knew something had gone wrong and decided to talk to him. 

"I will answer your questions later since even I am unsure right now. For now, you will have to excuse me." 

Saying those words, Aeliana appeared next to Nux and with a flick of her finger, she disappeared and entered a completely different world together with Nux.
