The Grey Hill covered about tens of thousands of square kilometers. Therefore, it was not easy to find a person on it, even for a wild patron from the school of patron, not to mention that the target was a powerful animal controller.
Given the survival ability and concealment ability in the wild, animal controllers were much better than pioneers. Because animal controllers were especially about getting along with wild beasts, they were good at concealing themselves in the wild. As an old saying went, "Animal controllers could live wherever wild beasts lived. However, wild beasts might not survive where animal controllers could live."
After circling around Grey Hill for 3 days, Crell gained nothing.
For Zhang Tie, those 3 days were his happiest period that he could even laugh out when in dream.
