The surroundings were dark, limiting our vision. However, it's not like we can't see anything at all. The path itself was still visible, and we can still see obstacles lying around.
The problem, however, was that the further we headed, the stronger the scrying eyes of the detection skill got. It was at the point where we'd get found out the instant we let down our guards!
[Master, we're almost there.]
Ember's words quickly returned my focus.
As she said, we were approaching the end of the "tunnel" we were in. It was heading straight at an angle, heading further down, but we didn't see any traps along the way, at least.
By estimate, we were just about 450 meters deep underground. It wasn't too deep, but not too shallow either.
"Everyone, be doubly careful. The enemies should be close by."
