Hold his Fort
The human traitors were dealt with, their corpses , and the SoulStar Fragments within had been extracted and stored safely inside Michael.
The energy influx he obtained from killing them increased his War Rune's refinement degree, resulting in ripples of origin energy passing through his body. Superior Constitution altered his physique to naturally absorb the energy in the surroundings and annex it at once. Therefore, the energy absorbed by the Dome of Extraction was annexed instantaneously, ready for Michael to use.
It was only a matter of time before Michael advanced to Tier-3, but that wouldn't happen before the Flag War ended. Michael doubted that he could absorb so much Origin energy in such a short amount of time.
