章 328: Secret room

"And that settles the exits," Mia said as she released a heavy sigh. 

Going around the entire underground took us an entire day, or however many hours the day and night cycle of the underground lighting was set to. 

Yet, unless there were exits that were so cleverly hidden that even someone like me, both with keen senses and the knowledge about the topography of the city we were scouting, couldn't find them...

Then, this underground city could be taken as secured. 

"What are we going to do now?" I asked, turning my eyes towards the girl. 

It was clear she was tired with just a glance. Yet, we weren't in a position where we could go to rest just because we were tired. 

'We are not there yet, but that's the kind of life we should be aiming for,' I thought, keenly observing the changes happening on Mia's face.
