Fox Ancestor, Winter!

Feng suddenly fell onto his knees while clutching his head and screaming in pain as if he was resisting something. 

But the truth was it was all just an act of Ace, and he was actually fine as he saw the pinkish streak entering his soul space, and before it could do anything, the Eternal Thief Fate Compass suddenly spun. 

"Hmph, wanted to enslave Sir Ace, not in my watch!" Moira's infuriated voice rang. 

The pink streak seemed to become extremely jittery and wanted to rush back, but Ace's true soul has become like an arcane prison as the Eternal Thief Fate Compass shone in dark sheen, and it was all done by Moira.

Ace was astonished when he saw how easily this compass could resist this soul brand. He didn't even need a system to block this kind of soul attack anymore. 

Furthermore, his true soul was now the Eternal Thief Fate Compass's territory, how could it let something inferior blemish it?
