As soon as Kana stepped foot into the cave, a cold chill suddenly ran up her leg, causing her to shiver. This instantly told her something was very off about this place. She took a step back and thought for a minute before using her spiritual qi to wrap her feet in flames. Only then did she step back into the cave.
Surprisingly she was actually still able to feel some cold pushing through the flames at the bottom of her feet, but not enough to really bother her. Another thing that struck her as odd was that the walls of the cave were very smooth. Not a single crack or crevice to be seen. It was almost as if whatever created this cave cut it with a fine edge.
