I thought One Piece was immortal ... Why did Ace die?

First: No one says that the One Piece is immortal, and an old man has died on the empty island.

Second: Xiaofeng didn't admit her death either.

Third: Personally, I don't think Ace will die. The reason is:

The sentence title 1 is the death of portes D. Ace, not the death of Ace.

The red dog wore the badge of one piece with white beard, and everyone knew that the era of white beard was coming to an end.

If you die, it seems that there is no need for two captains to save the peace behind you, just to buy time for Ace and Luffy to talk?

To sum up, ace should not die, but he will change his name. It could be Gerd ace. go on

I can't bear to have a white beard! ! ! ! ! !
