Can Ace hear the voice of all things?
No, or Not Revealed Yet Actually!
&quot;Voice Of All Things&quot; is even rare than Conqueror Haki. I don't think Ace have that. Especially since it's no way connected biologically.
Even though Oden and Momo both have that, but the prediction momo being a Ancient Weapon completely change this topic.
Or, the question would stand, How Luffy Did Got That?
