"Speaking of Immortal Gold..." Zhou Tong pondered for a moment, then took out his Nine-colored Vajra Ring.
This had originally been a protective artifact Zhou Tong had refined, and it had played an enormous role on his path to enlightenment. But after he advanced to become an Immortal King, it could no longer keep pace with his growth.
Over the past tens of thousands of years, Zhou Tong had upgraded the Three Divine Swords representing the three great sword arts, refining them into Immortal King artifacts. Yet he had never upgraded the Vajra Ring, because he had not found a path for its advancement.
The Three Divine Swords had a simple path of advancement: the three great sword arts. All three were Immortal King-level techniques, so following that path naturally allowed them to become Immortal King artifacts with ease. But the Vajra Ring was different.
The Vajra Ring had become an Immortal Artifact because Zhou Tong had activated the Immortal Gold Profound Meaning of the nine kinds of Immortal Gold comprising it. Once those Immortal Gold Profound Meanings had been linked together, the artifact had immediately transformed into an Immortal Artifact.
But what came after that?
Zhou Tong did not know how to turn this weapon into an Immortal King artifact.
The Immortal Gold Profound Meaning had already reached its limit. Zhou Tong could forcibly imprint the symbols and Dao patterns of other Great Daos onto it, allowing the artifact to transform into an Immortal King artifact.
But doing so would completely discard everything the Vajra Ring had possessed before. It would not be much different from refining an Immortal King artifact from scratch.
"Actually, my Vajra Ring once served as part of my attempts to comprehend the Immortal Gold Profound Meaning and the Divine Emperor Scripture." Zhou Tong recalled
