The exploration team split even more, but now their steps were being closely watched by Rain. They also received orders from the headquarters to change their direction in case Rain felt their traces getting faint. Fortunately, their steps left enough traces for Rain to keep track of them… he had some skills in the earth mage's path that broke the limit, so that helped to the point that Rain could tell their location one hundred kilometers away.

At the same time, the wind was picking up. There was a chance that those things were connected, and Rain reported this as well.
