There was also the fact that she was safe within the water, and so far, there had been nothing Loki could do to her. So she chose to keep fighting.
She made up her mind to only escape when her life was in danger. Unfortunately for her, when the moment of danger came, it was too late for her to escape.
A few seconds later, the Mind Bombs in her mind were detonated, and her mind was shattered. Her eyes immediately rolled into her head, and she fainted.
This caused the large cylinder of water to collapse and spread into the surrounding area. There was so much water that the whole place was flooded.
Loki looked at her corpse, unsure what to do with it. This was because Fenrir was no longer interested in her power core. Apparently, it had eaten its fill.
This brought a smile to his face as he said to himself, 'This is truly a fruitful Heavenly Battlefield. I have earned so much. Now all I have to do is wait to cash my final reward.'
