Since Mira was on a time limit, she decided to speed through the rest of the demons.
Her vitality might seem endless, but it certainly wasn't. With each lightning strike getting stronger and stronger and the rate at which they fell getting faster, it wouldn't be long before her body couldn't heal her injuries anymore. She'd also run out of Qi to block most of the damage before these lightning strikes stopped.
Luckily, she didn't need to waste any more energy than she already was by killing the demons, as the lightning that constantly surged around her was more than enough to turn them into dust. All she had to do was absorb their soul and move on to the next one.

After killing her way through 75% of the demons, another change occurred in the Gates of Heaven.
