One Piece - Chapter 1115

Oda, you great, magnificent bastard, you did it again.
You made your world even crazier and more interesting that before.

PD: I see Black and his crew are going fully psychotic now…

If my deduction is true, according to the drawings seen by enel on moon. Many powerful aliens once invaded moon and fight its inhabitants, the lunarians. The lunarians defeated and fell into earth, redline which is now mariejoa.

Somehow or another, the alien manage to descend into earth and form alliance with 20 kingdoms to defeat the great kingdom. They do so by drowning many cities, flood them with water such that it slowly drown many cities around the great kingdom. How did they do it? Most likely they are already in possesion of uranus. They also annihilate most lunarians. Lunarians eventually leave mariejoa(still not holy ground) and make encampment at the south of redline

With many seas become ocean called north, south, west and east blue, the great kingdom territory is divided. Many captured by 20 kingdoms. This time is when joyboy make his move. He travel seas with his crew and promise to collect ancient weapon all over the world. He first go to pluton in wano. And then poseidon. He didnt manage to get them all though, since somehow according to description in fishman island, he let the giant ship noah drown into sea, i think at this point, he is in contract with the world government(since fishman island location is so close to mariejoa, joyboy cant do much or else WG will destroy it). he and his crew wage war and joyboy ultimately defeated

Before defeated, joyboy manage to hide all ancient weapon just so WG cant retrieve them. The first one pluton hidden in wano where extremely powerful samurai reside. He do so by creating the waterfall and submerging 80% of island with nika power. The pluton goes all the way to the bottom of waterfall.

The second one, poseidon is never heard of by WG. Even until now WG is clueless since they never find “physical” object called poseidon.

Jesus f*ck when i said Oda cooked, HE COOKED
