What was out of place was that the killing cultivator that she fought with had a Life Ability called Madness. This Life Ability coats his weapons and fist with a black layer of energy that causes the target to lose their minds upon contact with the black layer of energy.
Each time she crossed swords with that enemy, her mind was afflicted by the Madness Life Ability. Eventually, her judgment became clouded, and she couldn't think straight anymore.
Things became a blur from that moment onwards. She still can't remember exactly where she went or what she did during the twenty hours of Madness. But when she regained her senses, she found herself in a city full of fragmented body parts.
Apparently, she had massacred the entire city during her blackout. She hadn't spared anyone. Both the babies in their cradles and the elderly with their crutches were cut into chunks of meat by her sword.
