After coming to Longteng, Xin Lin had learned that Xuan Spirit Beasts, even the birds among them, just like humans, all possessed very strong Cultivation talents.
Ordinary Xuan Spirit Beasts and Birds also had their ranks divided into different grades.
From First-level to Level 5, those were the common low- to mid-tier Xuan Spirit Beasts.
But once they reached Sixth-level and above, it became a whole different story.
It was like a Martial Artist breaking through to the Blood Realm, or a Spiritual Practitioner breaking through to Spirit Saint. The Qin Mountain Xuan Bird was the king of Qin Mountain, but Qin Mountain was just a small place. Although it was the Bird King there, it wasn't a Bird King in the true sense.
Only recently, after being treated by Xin Lin, did it finally break through the Sixth-level bottleneck, reaching the peak of Sixth-level, and it might even break through to Level 7.
