The more time passed the less comfortable Nial felt about the situation inside the two-element dungeon.
Because of that, he quickly retreated to the last intersection, where he took one of the other tunnels and entered it.
Moving without any hesitation, he briskly walked ahead making the three students feel astonished as they hadn't expected him to recover so quickly from the shocking things he had heard.
Their bodies seemed to have frozen on the spot after what they had just witnessed.
However, considering that Nial didn't see what they had seen, the description of the scene might not have been as harrowing as the scene itself allowing him to be relatively unaffected.
With that in mind, it was logical that Nial recovered faster than them.
Yet, it was their ignorance that made them gloss over the possibility that Nial was aware how dangerous the situation was, and that it was exactly because of this fact that he moved so fast.
