Time passed.
One day...
One and half a day.
Evelynn abruptly shot open her eyes and heaved a mouthful of poisonous breath that slowly mixed with the heaven and earth energy before disappearing. Her fair skin had a few places where it was slightly reddish as if possessing a burn injury...
Indeed, Evelynn became injured a few times as the Fiery Miasma Searing Poison retaliated against her when she tried to hasten the refining process. She didn't make a mistake but was too late in stopping the abrupt change in retaliation pattern.
It instinctively released its searing poison multiple times on being refined faster, but before it could affect her meridians or veins, she skillfully directed then towards her flesh, towards the outer skin, making the backlash negligible.
