Chapters
Law realizes Corazon can talk, and the Donquixote Pirate takes him out to sea to find a cure for his Amber Lead poisoning. Corazon plots with the Marines to steal the Ope Ope no Mi before the Donquixote Pirates in order to cure Law's illness. Law eats the Ope Ope no Mi and his illness is cured, but he and Corazon are discovered by Vergo who alerts Doflamingo of their treachery. Doflamingo responds by trapping Minion Island in a Birdcage. Doflamingo hunts down Corazon and kills him, but Corazon manages to have Law escape before he dies. The battle for Dressrosa continues as Law vows to avenge Corazon by killing Doflamingo, injuring the Shichibukai.
