Chapter 912: Nux…?

"That… haah… was amazing…"

Nux spoke with a tired look on his face.

"…"

Melia, however, didn't reply. Nux frowned, he raised his head to look at her and noticed that she had passed out.

Nux smiled as he shook his head. Then just as he was about to place his head on Melia's breasts and sleep as well, he noticed a Big Magic Circle forming under Melia.

Nux's expression changed.

He was familiar with this Circle. There was no way he could forget it.

That strange energy around it, those mysterious patterns which were completely different than the patterns they used to cast spells, and the most unique property of this Magic Circle of not using the surrounding Mana but its own energy to work.

Honestly, this Magic Circle was so unfathomable that it made Nux curious about his System's Origin. Just how could it do things that were considered impossible?
