In order for Li Mu to refine the array artifact of the 'Thunder Prison Grand Array', Venerable Lei Hong granted all his requests, allowing him to examine two other array artifacts - the Tier Six Thunder Suppression Stele and Tier Six Thunder Element Array Disc, to study their artifact patterns and artifact arrays.
Li Mu took over the two Tier Six array artifacts, which had already been successfully "refined" into Tier Six Spiritual Treasures. Upon examining them with his divine thought, he was immediately overwhelmed by their powerful thunder essence patterns and the complex Thunder Dao Law array.
Unlike the Five Elements Dao Principles, with their distinct cases of mutual generation and inhibition, the artifact patterns and arrays related to thunder were filled with a frenzied, destructive, and domineering aura, with lines of purple lightning that contained terrifying thunder intent.
