Chapter 818 of popular manga series "One Piece" won't be released until March 7 but story details have already emerged after scans for the upcoming chapter were leaked online.

Chapter 818 titled "Inside the Whale" will reveal more information regarding the red poneglyph. The red poneglyph was discovered in chapter 817 when Luffy and the Straw Hat pirates rescued ninja Raizo.

According to the chapter synopsis posted on the One Piece Forum, Robin translates the red Poneglyph. Inuarashi then explains more about the red Poneglyph. He explains that the red Poneglyph is one of four Road Poneglyphs. Each poneglyph leads to a map of an island surrounding Raftel. Once all four Poneglyphs are connected, Raftel's true location will be discovered.

This revelation excites Luffy and the Straw Hats because it will finally give them the first clue to the location of One Piece. However, their plan will have to wait until they are able to rescue Sanji.

Unfortunately, their excitement is cut short when they are told that they will need to find all four Ponegylphs. Thankfully, they do not have to steal the other poneglyphs. Instead, they will only have to copy the message. In the chapter, only three of the Poneglyphs have been identified. The two other Poneglyphs are in the possession of Kaido and Big Mom, respectively. Unfortunately, the location of the fourth poneglyph has yet to be discovered.

Inuarashi and Nekomamushi also offer additional details into the history of the Poneglyphs. It was created by the Kozuki Family who were stonemasons 800 years ago. The ability to read and decipher the Poneglyphs were passed down from each generation. Unfortunately, Momonosuke was not able to learn how to read the Poneglyphs because his father, Kozuki Oden, was executed by Kaido and the Shogun of Wano before he had the chance to pass down the knowledge to his son.

To learn more about how the story unfolds, fans of "One Piece" will have to wait until the release of Chapter 819.
