Pirate, the Fourth Emperor of the Sea Before Red Hair

[Pirates + no system + slowly becoming stronger + original pirate story line. On the day of Roger's execution, the ambitions of all pirates were ignited. Lake: "Father, the Pirate King Roger is dead. He made such bold words before he died. He is truly worthy of being called the Pirate King." "I also want to be like the Pirate King." After hearing this, his father Raeder dragged his weak body up from his chair and began to talk to himself. "Captain Rocks, the Roger who defeated our pirate group is dead. The man who has been called the Pirate King by the world for the past two years is finally dead." Then the father took out a small box and handed it to "Rake". "Son, this was snatched from the hands of the World Government when my father fled. It may be able to help you." Lake opened the box "It's a devil fruit." "Bird Fruit·Phantom Beast Species—Suzaku Form." After his father's death, Rick began his career as a pirate, competing with the four emperors with red hair, white beard, Big Mom, and Kaido on the sea. More than ten years later, he also accepted an apprentice named Ace. [The original story line will be slightly changed in the later stage, saving Fire Fist Ace and killing Momonosuke.
