"My other soul… piece?" Patriarch Empty Dream's voice seemed confused, "Forgive me child… but my memories are not complete, and I just regain consciousness after I sense soul contract on you. Can… you tell me… more?" 

Ace's eyes squinted when he heard this. 'He might be telling the truth, or demons would not let this happen. Besides, if I want to take advantage of this old ghost, this is the chance.'
