My technique worked against races' souls, and that Exomachines gave me the impression they got no soul at all. Or perhaps they got one that was like the AI humans invented, something that couldn't be accessed using the normal methods dealing with souls.
These two were bad news for me. Not to mention that wasn't the real trouble here.
Sara told me that she felt as if these Exomachines were trying to prevent us from getting out, entrapping us inside. But she was wrong!
I got why the enemy wanted to desperately kill her in such a way. The crux of this all lay in the deep holes which were lined up by the Exomachines.
The Exomanchines weren't trying to entrap us, but they were defending any assault at these holes.
And these holes weren't that weird or alien to me. I already saw and met the ones who created these before. In the early stages of the apocalypse, and just while I was trying to get out of Manhattan, I met these fierce and scary creatures.
