πI recommend The Legend of Sasuke: The Reborn One Piece to you. This book is a light novel written by the author, Ba Junyi. It meets your needs. The protagonist, Sasuke, transmigrated to the pirate world and joined the straw hat pirates. He fought alongside the original characters all the way and forged his own legend. In addition, this book had been written by the big boss of Qidian. It had a total of more than 400,000 words. I hope you like this fairy's recommendation. Muah ~π
