The fifty creatures in front of them were all at the Demi-god level. Although Erin didn't think anyone in the group would have trouble dealing with all fifty on their own, to come out of such a thing unscathed would be troublesome, even for her with the fire-shooting powers.
Perhaps she would have to actually push herself and treat the battle as a real challenge if she didn't want to get hurt.
This was why Erin was quite impressed with what she was seeing right now. The strange red aura was blocking all the incoming attacks, and they didn't seem to be weakening it one bit. Struggling to understand how this was possible, Erin decided to close her eyes to use other senses.
When doing so, she could sense it clearly now. With the help of her ability, she could tell that the power wasn't coming from Agent Four himself. Instead, it was coming from what he was wearing.
