After most of the Untamed Awakened fused with another Soultrait Symbol or upgraded their existing Soultraits, they left for the training ground to get used to the changes.
Nobody knew how many days they had to prepare for the next battles and everyone wanted to be as prepared as possible.
Michael liked that about his subordinates. They worked hard to grow stronger. If their training regimen was lackluster, or they ended up idling around, Michael would regret providing Soultrait Symbols and Upgrades to strengthen them. Fortunately, that was not the case.
The only downside was that he used more than half of the 126,000ish SoulStar Fragments he procured until now.
He didn't have enough SoulStar Fragments to upgrade Soul Grimoire to 6-Star, but that was okay. He had 90ish Lords, their Awakened, and Reinforcement to kill. There was no way that he wouldn't have enough SoulStar Fragments to upgrade some of his Soultraits once the Regional War was over.
