Not Even Celestial Kings Can Open It?

In Li An's opinion, even if a Celestial Alchemist did not completely forsake cultivating for alchemy, it would still greatly affect his or her advancement in cultivation. An expression of disbelief could be seen on his face as he asked, "Master Duan, y-you're also a Great Overarching Golden Celestial?"

As a Nine Palaces Celestial Duke, Li An had discovered earlier that his Divine Consciousness could not probe Duan Ling Tian's soul. Therefore, he was unable to determine Duan Ling Tian's cultivation base. He did not think much about it since there were many cultivation methods that could prevent others from investigating the cultivators with their Divine Consciousness.

Duan Ling Tian chuckled and feigned a hint of contempt in his tone as he spoke, "Great Overarching Heaven Golden Celestial?" Then, he deliberately extended his Divine Consciousness and revealed his soul aura that was concealed by the Profound Divine Metal.
