10,000 Meters Under the Sea

"It's really dark here," Hancock said while leaning on Xin who was fishing in the darkness of the underwater ocean.

The only light that they use is the light ball that Xin creates when they dive in the Undersea Waterfall.

"Is this your first time coming in this part of the ocean?" Xin aks.

"Yes, the Kuja Pirate did not experience underwater adventure because our ship can't take it, and also the Traveling Snake can't take the pressure here," Hancock said.

"Well the pressure here is not a joke, it can easily crush iron just from pressure," Xin said.

"So what are you doing Xin," Otohime asks while looking at Xin who is currently fishing using a gigantic rod.

"Of course I want to try to catch a fish, I want to try to taste them if possible," Xin said while pointing to the gigantic fish that is bigger than an Island swimming outside.

"You can't eat them, some of them are poisonous, while the others are not edible because of their tough meat," Otohime said.

"What about those crabs?"

"You mean the Giant King Crab? Well, I think they are pretty delicious, but you still need to have the strength to crack their 3 feet thick shell,"

"I will take that for you Xin,"

"No Hancock, I said you will login to be crush into a pulp if you try to go outside,"

"Do you want me to tie it and drag it here?"

"Queen Otohime, that's not a problem, the problem is the water is too cold for you to swim," Xin said while pointing at the ship that was already covered with ice.

"Well you are right," Otohiem suddenly remembered that she is also wearing a thick jacket right now.

"Just let me fish silently here," Xin said," So how far is the Fishman Island here?"

"Fish-man Island is an underwater island that dwells 10,000 meters below sea level in a giant hole that goes under the Red Line at the bottom of a deep trench."

"The island resides in a giant double-layered bubble floating above the seafloor, seemingly filled with about half water and reef and half air."

"Ryugu Palace rests in a smaller bubble on top of the main island's bubble. It is illuminated by the Sunlight Tree Eve. It serves as an underwater gateway to the New World for those who do not wish to cross over the Red Line above."

"With our speed we will arrive there for about 2 to 3 hours," Otohime said.

"Ok let's wait then," Xin and Hancock then continued fishing. They caught a bunch of seafood on the way.

Like Giant Crab, Giant Oyster with Giant Pink pearl inside, Giant Muscle, some edible fish, and some glowing fish.

Xin keeps looking around to check if they can see the gigantic Kraken in the original story but after passing on the Underground Vulcano, he did not even see any Kraken.

...….

After hours of travel, they reach the deepest part of the Red Line, in the depth of 10,000 meters there is actually light coming up from the root of the mangroves in Sabaody Archipelago.

"So this is the legendary Fishman Island," Hancock amazed seeing the gigantic bubble encasing an Island inside.

Fish-Man Island is the home of the fish-men and merfolk. It serves as an underwater gateway to the New World for those who do not wish to cross over the Red Line above.

Though it is literally directly under the main seat of power of the World Government, Fish-Man Island was under the protection of Whitebeard Pirate.

The island is encased in a giant bubble, allowing human visitors to breathe. For World Nobles, it is also one of the few places in the world where their ability to summon a Marine Admiral as they please is not so easy to accomplish.

"So where's the entrance?" Xin asks looking for the entrance, in the origin story, Straw Hat Pirate forces their way inside of this gigantic bubble to enter.

But their plan totally failed, they forgot the bubble coating of the Fishman Island is a double layer, if you come in the first layer the ship will fall in the air-filled stretch.

Of course, the next layer is a sea under the sea that has strong water currents that almost drown the whole straw hat pirates.

Of course, Xin's ship is different, this ship is a self-sustaining ship that can fly, dive and float everywhere from Sky, Sea, and even Land.

"Let's enter to the entrance up in the top of this bubble," Otohiem point the big gate up in the Fishman Island

Xin then common the ship to swim to the front entrance where a bunch of Merfolks were waiting for them.

"Halt, who are you? State your name," A soldier shouted.

"Don't move Xin, let me talk to them, they are Ammo Knights of the Fishman Island," Otohiem said.

The Ammo Knights serve as the royal guards for the Neptune Family on Fish-Man Island.

They wear large striped spiral shells as helmets and shoulder pads with their eyes covered by a black mask of some kind. The helmets have a spike sticking out in the front, similar to that of a unicorn. They carry tridents with them.

"Halt, it's me Queen Otohime," Otohime shouted coming outside of the SHip.

"Fast! Report to the King, Queen Otohime is back!<" The Ammo Knight shouts at his comrade.

Queen Otohime walk on the Ammo Knight and smack him on the face and said," Don't shout, at least, try to do it silently with elegant, we have visitors,"

"I understand Queen Otohime," The Ammo Knight Politely said, he looked pleased even though Otohiem smacked him.

"T-That's pretty unique," Hancock said, seeing how Otohiem treats the soldiers of her kingdom, but surprisingly, the Fishman looked pleased after getting a smack on the face.

"Escort us back to Ryugu Palace, I want to go back personally, my children sure miss me now," Otohime said.

"Yes Queen Otohime," The Ammo Knight said," open the gate, let The Queen escort enter,"

Two gigantic sea kings swim in the air using air bubbles in their body escorting Xin's ship straight to the Royal Palace.

"Let's go straight to my children's room, I will introduce you to my children," Otohime said.

"Sure," Xin said, he can't wait to see the Poseidon, the current heir of the 3 ancient weapons.
