Yuan Ming was naturally unaware of the little tricks within the Artifact Spirit's mind and continued to operate the secret technique, swiftly refining the runes at the four corners of the Shura Blood Devouring Map.
Though these four runes couldn't form a rune formation, their effects were interconnected, used to control the changing size of the Shura Blood Devouring Map and the function of spatial displacement.
He continued to channel his mana, spreading it deep into the Shura Blood Devouring Map, and soon encountered more runes, this time eight of them.
Yuan Ming followed the same method, continuing to refine with the secret technique, and quickly refined these eight runes as well.
These eight runes formed a rune formation that was used to control the Artifact Spirit, the Blood-colored Skull, the red-clothed woman, and others.
