The next chapter of One Piece, chapter 907, is set to arrive June 11 and it will reportedly offer some insights into the secrets of Mary Geoise, the Reverie location.

The plot is steadily moving along the Reverie arc and fans who have already caught up with chapter 906 will know that many characters have already met at Mary Geoise - Rebecca, Vivi, Leo and Shirhoshi bonded over their shared connection to Luffy in the last chapter.

But there were some other mysterious elements to chapter 906 that need some further explaining, like the unidentified person holding a new wanted poster of Luffy and looking at a strawhat that looked like Luffy's.

And fans got a glimpse of Doflamingo inside the prison under the castle where he is being held in solitary confinement. Doflamingo actually revealed that assassins are on their way to Mary Geoise.

OtakuKart reports that the assassins are coming to murder Doflamingo because they think he knows the secrets of the National Treasure of Mary Geoise and want to make sure that whatever he knows doesn't get out.

The Anime Scrolls speculates that the National Treasure may be the ancient weapon Uranus.   According to the Anime Scrolls, these are the editor's notes, although they are apparently not that accurate: 

"Reverie and so on heading to the Wano State !!"
"The world is in chaos .. !?"
"The strongest hero of the new world bursts into the Wano State!!"

OtakuKart thinks that the National Treasure may also be an ancient treasure that will shake the world or that it could be the corpse of some legend.

Newsweek said, meanwhile, that it didn't think Reverie would start in earnest in chapter 907.

One Piece chapter 907 will be out in Issue number 28 of Weekly Shonen Jump arriving 11 June 2018. We're hoping that we get some answers to all of these questions then.
