Rui used Seismic Mapping to search for the largest source of seismic radiation and began heading towards it as fast he could. After some time, he ran into a herd of deer numbering hundreds, which was quite large. And he tailed them at a distance, careful not to alert them of his presence, which was easy enough when one considered that they were resting.
Now he just had to pray that this herd would be targeted so that he could get a close look at it for once.
As time passed by, his hoped grew more and more dull. He waited, but nothing happened. His patience wore off and he felt tired from simply waiting and doing nothing.
In a way, he had come to develop respect and admiration for predators. Predators often had to endure agonizingly long waits before a realistic possibility of a successful hunt occurred. That respect extended to hunters as well. These Martial Artists that regularly took hunter-class missions were definitely not to be trifled with.
