To be precise, the Ghost King Palace had already been refined by Jiang Li.
Jiang Li's artifact refining technique was known as "Great Thousand Spiritual Transformation," a technique she created herself during her time as the Mystical Lady of the Nine Heavens. It was incredibly powerful, outrageously so.
While other artifact refining techniques focused on how to remove impurities from materials and advance the path of artifact refining, the Mystical Lady of the Nine Heavens had taken a different approach. She directly created the Great Thousand Spiritual Transformation, imbuing anything that could become an "artifact" with spirituality, granting them intelligence.
In layman's terms, when other people were still researching how to make bricks fly with their power, the Mystical Lady of the Nine Heavens could already turn bricks into artificial intelligence.
"You've become a bit too intelligent."
