The air in the Sky Secret Realm was heavier than Lin Xuan had imagined, carrying a primordial ancient aura.
No wonder, this Sky Secret Realm is a secret realm passed down since ancient times, and can be said to be extremely mysterious.
Despite many years, the major powers of the Heavenly Martial Continent sent elite disciples in, yet they have only explored a fraction, barely uncovering the overall picture.
In other words, more than eighty percent of this Sky Secret Realm remains untouched.
After analyzing these matters, Lin Xuan's expression turned sour.
However, he didn't give up; while he could forego other Heavenly Materials and Earthly Treasures, he must find the Heavenly Nether Bird.
"Don't worry, Little Xuanzi, based on my judgment, the Heavenly Nether Bird is definitely in this secret realm!"
