Eating a rank 8 material was an arduous task for a rank 7 existence. Noah had to bathe the monkey's arm inside the dark world while his technique enhanced his destruction to absorb its nutrients slowly.
His tissues cheered whenever that energy flowed inside their cells and enhanced their power. The arm forced his body to advance significantly, but that growth didn't match Noah's expectations.
His body didn't reach the halfway mark of the upper tier even after Noah ate the whole arm. The improvement was substantial, but he could barely sense it.
'My body requires many rank 8 materials to reach the eighth rank,' Noah concluded after inspecting his condition.
That conclusion left Noah disappointed, but part of him knew that such harsh requirements would be a good thing in the end. The harder his path toward the superior ranks was, the stronger his centers of power would become once he advanced.
