Speculations Finally, One Piece is

[Flodor]

One Continent...
That's why Roger laught.

The 'Treasure' is to make the World again before flooding as One Continent where its no more hard to travel. No more Log Pose to go further.

I guess OP world is kind of donut with a big ocean in the middle aka 'All Blue'.
'Them' put Red Line in the Middle > flood > current Map with One Line of earth and multiple islands and N S E W Blue

Since the beginning its not Pirate as Pirates of Caribbean, its Pirate as Neo.
No Gold , no cross on a Map, just vengeance for Joyboy that was annihilated like the previous World before Void Century.

Would surprise me if that fagggot made some shit up like this

So what do you think it will be ?
The path all along.
The mechaheart.
A treasure.
?

Bro thought he cooked something

Some sort of trigger that will destroy the Red Line and join all the seas together that makes it "All Blue".

Let see in 10 years if i was right.

But everything matches, Luffy destroying Redline premonition.
Shanks being a CD but is not agree like Joyboy was with the 20 Kingdoms.

 

[Fuyuppe]

One Piece was some'THING' left behind by the previous Joy Boy.

The one piece treasure is the mechaheart

Minamoto is the Buggy of worstgen: even when he tries to troll, he fails upwards into success.

I hate this theory

it makes no sense

The seas are already joined via fishman island and reverse mountain. There could even be other passageways under the red line for all we know.

Even there was no red line that still wouldn’t create the all blue. Because fish would still live in different locations due to differing ecosystems.

The real world has no red line, yet there is no all blue irl because different species of fish evolve for different ecosystems. This is why the all blue is thought of as an impossible dream.

The only way an all blue could exist is if it was man made. I’m guessing all blue is the sea around Laugh Tale. The ancient kingdom created it so they could eat whatever fish they wanted.

If Redline is artificial then they made it with canals like Suez one to allow navigation.

We agree that AllBlue has existed (articial ocean or not).

Even if All Blue, you could find all fishes only on a minor portion of it.
Its' more All Blue == One Blue

 

[Herrera95]

No. It is a real treasure. And is not only at Laugh Tale. Since we've learned Pluton was at Wano there is a high possibility that it may be Uranus there.

 

[Peroroncino]

no shit
