Returning to Third Medicine Valley, Gu An's face blossomed into a smile.
In just one night, he had transformed from the ninth layer of the Divine Thought True Immortal Realm to the ninth layer of the Free Immortal Realm, a groundbreaking change of strength.
Had it not already been daylight, he would have wanted to continue breaking through.
The breakthrough in cultivation level consumed nearly fifty million years of his life span barrier, leaving Gu An with over sixty-seven million years of life remaining.
He felt there was still hope for a successful breakthrough.
After reaching the Free Immortal Realm, his perception of the Great Heavenly Spirit Land became clearer. He could confirm that both the Immortal Dynasty and Holy Court were harboring Free Immortals. Once the Free Immortals go to war, it could very well involve the entire world. If he could transcend the Free Immortal Realm, Gu An would feel even more at ease.
