Secret Wolves were experts when it came to hiding their tracks. They could escape into the shadows anytime, and even the most skilled hunters couldn't find their tracks, even with a wolf incarnation ability.
Lin Yun had captured the aura of the Secret Wolf with his Magic Array among the countless mana fluctuations. But this aura had already completely disappeared. In other words, the Secret Wolf might have already sensed that it was being tracked and snuck among the Frost Wolves.
This was definitely a headache...
There were thousands upon thousands of Frost Wolves here. Finding a Secret Wolf among them was impossible, even Lin Yun wasn't that formidable.
But he was truly reluctant to give up.
Secret Wolves were very rare.
