Just before finishing the battle against the group of nearly a dozen Frozen Yetis, while facing the last of the six yetis that he was fighting, Xie Feng managed to somehow sense a slight change in the temperature of the place; precisely speaking, there was a change in the gusts of wind blowing across the length and breadth of these lands of ice and snow. Although this change was so minuscule that it could easily have been overlooked during the fervor of battle coupled with the mental pressure of having seen nothing but white snow for half a day, Xie Feng managed to perceive it with total clarity as if it were rays of light in the middle of the night.
