Yin-Fire, Comprehended!
Just 3 months before the Secret Realm will expel all of the participants due to the time limit, Mira finally felt something happening during her meditation. She couldn't help but reveal a slight smile as she's had about enough of trying to comprehend Yin Fire.
Her body soon started to feel weird and she started to feel a change in her soul as well. She felt all of her comprehension in the Fire Element start to increase at a surprising rate and at the same time, it started to mutate.
Her Physique seemed to understand that Mira had someone comprehended the Fire Element, but her Physique won't allow her to utilize this kind of fire and it started to mutate in what Mira perceived Yin Fire to be.
This is why it took Mira so long just to reach the entry-level barrier of comprehension. It's because not only did she need to comprehend the Fire Element, but she needed to understand what Yin Fire is or at the very least what she perceived it to be.
