Pirate: I Got the Silence Fruit

"Mr. Yi Fan, you have traveled to the world of pirates. Have you eaten Devil Fruit?" "Well, I ate it, the Fruit of Silence." "You joined the navy and must have learned amazing physical skills, right?" "Yeah, I learned it, iron block." "The fruits are not good, and the physical skills are weak. What about the Haki?" "Well, I'm awake and seeing things." "... Then, how did you get to where you are today?"
