Yale Harrison was the personal soldier of Owen Bertram and was much more capable than Eric Reed. He had been very cautious throughout the journey, setting ambushes multiple times in case they were followed, and almost exposed the Magpie.
Later on, the Magpie dared not stay too close. Fortunately, Little Ghost's older brother, Dave, helped track them by hiding in the shadows of the forest.
This unexpectedly helped Dave realize the divine power of "Shadow Leap", which allowed him to jump directly from one shadow to another. However, his current jumping range was limited and could not exceed 60 feet.
But this slowed down Yale Harrison's pace, and it wasn't until this morning that they arrived at the "Lion Cave" in the deep mountains, as mentioned by Owen Bertram.
