@Salah WG you were correct in theorizing that the arc will end/almost end in 1123 but the new villain is not being shown
It's over if Narrator said it this Chapter, but if not, then there is still a Tiny Chance for Next Chapter.
Man With Burn Scar have No Witnesses & his Power is Sea Related, so He isn't gonna face SHs on an Island
As long as SHs didn't reach Elbaf yet, then this Man can Attack them at any moment
Also it could be a Hint or maybe Unrelated
But Usopp calling Elbaf "Dream Land" reminds me of this:
Usopp called Skypiea "Dream Inside a Dream"
It was when They were getting sucked inside a Whirlpool, which ended up taking them to Skypiea.
And it makes perfect sense cuz Usopp didn't just say that Skypiea is a Dream, He said it's inside another Dream, meaning Luffy was already in a Dream Adventure, and if you go back to Chapter 2, Luffy indeed started his Journey by entering a Whirlpool
It's really interesting how the Guy who ate Nika DF, as soon as He set foot on the Sea, a Whirlpool appeared out of nowhere to swallow him, and Luffy never managed to Awaken his DF despite all the crazy things He went through, but when did He awaken it? When He finally got swallowed by another Whirlpool before entering Wano
Oda talked in SBS before about Rotational Energy & how it's Energy of Everything (Probably ties to Lineage Factor & DFs & Haki ... etc)
Even Luffy's Village is called "Windmill" Village which is all about creating Rotational Energy (And Haki being stored in a Wind Rope further hints at the connection) ... etc
So i'm pretty certain that Whirlpools have Huge Importance, and if Man with Burn Scar is the one who summoned it in Chapter 2, then He should face Luffy before Elbaf
