Kapitel 453: Chapter 148 - Perserios territory - part 2 - Dark clouds on the horizon (part 5)

"Is changing the oxygen levels an efficient way to spend mana?"

Zoemi asked curiously as he and Miriette walked down yet another flight of stairs, searching for their way out.

"It is, actually. I am not erasing or creating anything new, just pushing aside or bringing back what is already there. That said... how in the world are we not outside yet...?"

The helmet-wearing girl answered confidently, before groaning and waving her hand in an unspecified direction.

Basically, the other day they were shown through one of the outposts and assured that every single one has been built in the same exact way.

"This here should be the exit, right?"

*knock* *knock*

The girl asked tapping her knuckles against a solid rock wall at yet another dead end.

"It really should..."

Zoemi nodded and touched the wall with a concerned expression.
