A few minutes passed since the beginning of the fight, yet nothing in particular happened. Mira and Robin kept dashing around the battlefield, dodging as many attacks as possible.
Mira, of course, wouldn't be Mira though if she didn't retaliate and even when she's pushed to such a state, she still managed to kill off a few beasts. Unfortunately, even though she was able to take a few of them out, she was only able to kill a few of the beasts who dared to attack her head-on.
If not for her sending all of her Qi and Ice Dao comprehension into her wings, she would've been able to take out a few more, but doing so would be a huge waste of time and energy. Once her new wings are finished, she'll be able to go on a complete ramage rather than only being able to aim for the weaker ones while being careful of attacks from behind and above.
The only problem she might have is dealing with some of the stronger Rank 6 beasts who have yet to appear in front of her.
