Invincible System Start From One Piece

The Princess40m ship already sail for more than 5 hours, leaving far Alabasta, following the Log Pose.

After lunch, Koby back to working out. While Nami when to her Workroom behind the Wheelhouse, with Robin leisurely relax after a morning workout and lunch reading book at the Outdoor Lounge on top of the Wheelhouse which was the Flybridge.

While Adam is laying on his back on the Sunbed at the front side of the Flybridge. Adam was thinking how to make his own huge island ship.

" The best way is to use a Devil Fruit, like "Golden Lion" Shiki. He use his Float Float Fruit to float an island and built his own fortress. Thats the only best way."

" But, I want to build the shape of the island my self, and can also sail on the sea.. "

" The island-ship height should at least 1000m above the surface of the sea to prevent the huge waves, with the hull around 300-500 below the surface. The hull is the most important thing, it need to be welded very well so that it can carry the huge island, and float on the sea.

Adam look at the Devil Fruit section from the One Piece World Store.

" Island Island Fruit, is a Paremcia-type Devil Fruit that allows the user to create an island at will. The size depends on the user strength, while the layout depends on the user imagination."

Looking at the introduction of the Island Island Fruit, Adam blood is boiling. Thankfully, the Devil Fruit was available and can be bought. If an evil people eat it, he can easily fly above a city or an country, and directly drop an island he create. Adam can already see how powerfull the Devil Fruit was.

But, what Adam wants was a sailing island, or it can be also called a island-ship. The trouble was how to make the hull, the island will be very huge, so the hull of the ship will be very huge too.

While the propulsion system Adam can make himself. In Adam previous world, Adam was called Iron Man because of his genius brain. But they dont know that actually Adam were more smarter than Tony Stark. Anti-gravity, nuclear fussion, is nothing in Adam eyes. The material to build those Adam can buy in the Earth Store..

" Adam !! "

Adam stop his thought on the island-ship, when he heared Nami shout from the Wheelhouse.

" What is it? " Adam come to Nami quickly, Robin who was reading on top of the Wheelhouse at the Outdoor Lounge also come.

" This.. look. I think the Log Pose is broken, it is pointing up.. " Nami said pointing to the Log Pose attached on the table of near the Wheel.

Adam and Robin look at the Log Pose pointed by Nami.

" No Nami... Its really our next journey.. The Sky Island.. " Adam said shocking Nami and Robin.

" Sky Island? Is there really an island in the sky ??? " Nami ask shockedly.

" Interesting.. " Robin licked her lips.

" Umm. There is.. With my Observation Haki, i can already see it. Its above us.. " Adam said looking up, then he look at Nami and Robin with a smirk.

" Theres gold... and a Poneglyph.. " Adam said making them shocked more.

" LETS GO THERE!!! " Nami said quickly excitedly

" Poneglyph.. How do we get up there ?? " Robin ask suddenly.

" We will sail using a Knock Up Stream... But i dont know when it will happened next, it happaned 5 times in a month. Theres someone who knows when will the next rissing current is at Jaya Island, we go there first.. " Adam said.

" Knock Up Stream? Jaya Island ? " Nami ask confusedly.

" I dont know much, but i know someone who knew about the Knock Up Stream. He stays at Jaya Island its around 40km from here.. We can get there in 1 hour.. " Adam said pointing in distance then he went to the wheel and change the direction.

" My Observation Haki still cant find that far in distance.. " Nami said..

" Umm.. Me too.. " Robin said .

Yes, Robin yesterday already awake her Observation Haki. With her past experience running from the Marines and World Government, Robin easily awakens.

" With 50 times cultivation speed, you dont need to worry." Adam said giving them a grin.

Nami and Robin nodded.

" Oh look.. Come lets go outside.. " Adam said looking up at the sky not far and pull Nami and Robin hand outside.

Adam held the hilt of the Enma in his left waist, then he pulled out the blade leaving the saya which was stucked in the dark green sash wrapped around his waist.

With a swing of his hand, a green "Flying Slash Attack" quickly fly toward a certain cloud above.

Soon, the cloud disappear, and a huge black thing fall from the sky toward the sea below far from the left side of Adam"s yacht.

" A GALLEON !! " Nami shout shockedly.

" A HUGE GALLEON ! " Robin said added .

Boom !!

The galleon fall to the sea, making the debris fall everywhere.

" Ill go.. " Adam said while taking off his clothes and the two sword, leaving only wearing his dark green u.n.d.e.r.w.e.a.r.

Nami did not care, but Robin looking at Adam"s almost n.a.k.e.d figure felt embarassed.

Soon Adam came back with a map from the ship wrecks.

" Here.. Look at it.. " Adam said giving the map and taking the towel from Nami.
