Navigation: Burning Black and Turning into Hellfire Is Not Too Much.

Blackening is ten times stronger and whitening is three times weaker. Because you chose to join the Blackbeard Pirates, your Burnt Fruit turned black into the Hellfire Fruit, gaining the ability to seal and devour! Because you chose to compete with Luffy for the Pirate King, your Overlord's Haki turned black and became the evil Overlord's Ghost Aura! Because you killed the white-bearded father with your own hands, your knowledge color became domineering and darkened, and you gained the ability to hear the voices of all things, foresee the future, and kill with knowledge! Because you defeated Grandpa Navy Hero Garp, your armed domineering power turned black and you returned to your original nature and transformed into colorless armed domineering power! … The final battle. When Luffy recalled the death of Ace and the bond between brothers, he once again stood up tenaciously and prepared to face a powerful enemy. Finally, the villain slowly took off his mask: "Luffy, did you think of me just now?" … Ace: "Being black is ten times stronger. Since becoming black, my waist is no longer sore, my legs are no longer painful, and I sleep better!" This novel and its characters are purely fictitious.
