Dragon Sorcerer in One Piece

What would you do when you end up in a world full of adventure and great stories? What would you do when you obtain a power of 12 talismans from Jackie Chan Adventures? It's a new adventure for our main character David and he will witness stories he knew and interact with. Note: I grew up watching Jackie Chan Adventure and One Piece. This is fanfiction and the cover picture isn't mine but it looks awesome so I post it. Please support the original work of One Piece and Jackie Chan Adventure. Give me tips and advice on how to improve stories and world-building. Thank you
