The Elbaf part of One Piece gives us one surprise. Fans have expected this part since Arc Little Garden of Arabasta Saga.
One of the surprises is information about the cruel twin brother of Shanks, Figarland Shamrock. Chapter 1137 One Piece not only confirms his identity, but also revealed that Shamrock is the commander of the holy monk.
Moreover, the ARC Elbaf also goes into the legend of the god Nika. The Elbaf land has an ancient text called Harley, containing important events in history. Because it is written in an ancient language, only Robin can read.
Chapter 1138 also revealed an important hint of world history through a huge mural. However, it also revealed a subtle suggestion about Luffy's true dream, the dream he could only realize after becoming a pirate king. The manga revealed Luffy's real dream for the first time in Wano Country Saga, and now we have gone closer to finding it.

Luffy's dream in One Piece may be related to world history
One Piece Chapter 1000 has a Ace scene revealing Luffy's dream with Yamato. Although when he was young, he and Sabo laughed at Luffy, but Ace believed that Luffy could make that dream a reality. After reading Oden's diary, Yamato knew Roger's true dream, just like Luffy's dream.
In chapter 1060, Luffy revealed his dream to the entire crew after the battle in Wano ended, even though at that time, it was still not clearly detailed with the reader. They were all shocked and amazed when their captain revealed that it was the dream he could only achieve by becoming a pirate king.
Even when Roger revealed it to Oden and his crew, everyone did not believe it. The dream sounds so impossible that people are always shocked after listening to it. However, that's what Luffy wants to do since childhood. In chapter 1138, Franky was surprised at the mural, where people from every race fight together with a common entity.

Ripley said that the history they were familiar with always talked about wars between races, but never a cultural exchange. She even believes that the mural is nothing more than the child's dream, consistent with the possible ambition of Luffy in the past. Luffy's dream in One Piece may be involved in bringing people together and letting them live in harmony. With the way the story is happening, it is likely that the great war will begin after Luffy becomes a pirate king.
During his journey, Luffy made friends with all kinds of people and races, including Samurai, giant, tiny Tontatta, fisherman, Skymiea and many other races. They all will quickly run to him when needed. Perhaps Luffy wants a world without discrimination and bloodshed. The world was ruined after the world government was established more than 800 years ago. If all races are united, everything will return to before everything gets worse.
