Gu An watched the battle unfold while he waited for his cultivation level to become completely stable.
During this process, the battle between the man in silver armor and the mysterious Great Demon in his eyes gradually slowed down.
The Dao rules of the Celestial Extreme Nine Heavens were indeed rich, providing great benefits for Gu An, and his aptitude in the Way of Cause and Effect also greatly improved.
At that moment, he even considered relocating the Daoist Field of the Beginningless to the Celestial Extreme Nine Heavens.
Of course, he merely thought about it; while the Celestial Extreme Nine Heavens were appealing, they were even more dangerous.
So far, he hadn't seen any beings in the Celestial Extreme Nine Heavens with a cultivation realm lower than that of an Innate Golden Immortal.
