Previously, when Lin Fei used his Qi-Observing Divine Eye, this grand formation appeared as nothing more than a cloud of spiritual energy swirling in the mountains. Now that his vision had upgraded to the Spirit-Observing Divine Eye, he could clearly see the array in its entirety.
It was a translucent green dome of light covering a radius of several kilometers. The barrier shimmered with spiritual radiance, glowing in the dark of night like a massive lantern set deep within the mountains.
Lin Fei watched as Huo Yan reached the edge of the formation and sniffed the barrier. Clearly, the little Spirit Fox could see it, which left Lin Fei astounded. He knew that creatures with intelligence existed—they were known as Spirit Beasts, and above them were Monster Beasts—but from the information Qingqing had imparted to him, he knew they were rare, found only in unique locations like the Cultivation Trial Ground. He was certain that Huo Yan was one of these rare Spirit Beasts.
