Of the 9 Divine Metacs that he gained from hunting and killing divine beings, he left out the Obscuring Mist Metac, the Will Erosion Metac, the Thousand Cuts Metac, and the Bone Armor Metac. These four belong to the Deceiver Pathway, the Mind Hunter Pathway, the Killing Pathway, and the Death Pathway.
The five remaining Divine Metacs were the ones he chose to upgrade. The Wolf Emperor Metac, the Wood Tyrant Metac, and the Crane Master Metac were part of this group.
After he converted these five into rank 8 Divine Positions, he put them into a circular formation. Fenrir was at the center of this circle. So the five of them were to be sacrificed to uplift Fenrir.
In order to achieve this, he summoned the expertise he gained from fusing with the Domination Supreme Metac. This caused his mind to churn with thoughts upon thoughts of actions.
