I Own One Piece, and I Can Avoid It at the Beginning

In the year 1518 of the Haiyuan calendar, the East China Sea where the new king Shichibukai's "Rein" is located was rated as "the most livable sea area in the world". The source of everything begins when Ren wakes up on the beach of the Music Island 'Irelia'. That day, he discovered that the 'Pirate King' Gol D. Roger lived inside his body! "Why do I have this strange thing in my body? Lao Deng, can't you disappear?!" ———— "Hey, Lao Deng, teach me to become stronger." "Oh? Have you finally figured out how to help me start a new era?" "How is it possible? I will personally end your 'Age of Discovery'!" ———— On the eve of the war. Facing the "Fire Fist" Ace who was about to be executed, the pirate king who always laughed boldly expressed his request to Ren. "Ren... This is my last wish, please... Save Ace for me." "Please, Ren!" Looking at Roger's eyes that he had never seen before, belonging to a father, Renn clicked his tongue and tightened his grip on the handle of the knife wrapped with black and red lightning: "Got it." "How could I refuse a father's request?" ... "Hey, Whitebeard, why are you inside me?" Why are there more and more weird things inside me? —— Also known as "Pirate, the legendary Lao Den lives inside me". "Pirates: My roommate is Roger?"
