I trained all the Luffy pirates into Generals

Roy traveled through the world of One Piece and awakened the strongest protagonist group cultivation system. Raise Luffy and give Naruto Kai’s Eight Gate Dungeon inheritance. During the battle, all eight doors were opened and Akainu was beaten violently. Cultivate Zoro and give him the Demon Slayer Breathing Technique. Compete with Hawkeye for the world’s swordsman. With a hundred times the breath of the sun, he can crush Hawkeye and become the world’s best swordsman. Cultivate ‘Robin’ and give the full-time hunter ‘Bisuki’ the inheritance. Transform into Thousand-Armed King Kong Barbie during battle! … When Luffy went to war with the World Government to save his father ‘Monkey D. Dragon’. The World Government was shocked that every member of the Straw Hat Pirates was actually a general.
