From Impel Down to the Multiverse

On the three-dimensional map, except for the Reverse Mountain Canal and the Mariejois Ring Railway.

There are only a few unusual ways to travel between the Four Seas and the Grand Line, including:

The snail boat of Derma 66 can directly climb the Red Line continent; Amazon Lily’s Sea Beast pulls the boat; takes the Skypiea’s western sky route; similar to Flying Pirates’s Ability User method; free-hand rock climbing through the Red Line continent (refer to Fishman Tiger); swims through the Calm Belt (refer to Rayleigh);

The other is the seabed route, mainly Fishman Island and Umit, the sea king.

Fishman Arlong took the remnants of the Sun Pirates regiment to East Blue, and the chapter Fishman Hachi, who had escaped from the Marine battleship halfway, returned to Fishman Island from East Blue. Both of these circumstances indicate that Fishman Island knows something. Seabed's hidden routes.

As for the sea king Umit, it is called the "deep ocean current" because of his transportation fleet, which can use the deep ocean current of the seabed to travel to and from the various Sea Territory.

"Organizing the current mode of transportation, if air transportation is adopted, our current largest-class transportation airship can carry 12,000 tons at a time." Samer said with a piece of data.

New Shiki shook the head: "Small-scale transportation is okay. If we want to form a fixed route, our current manpower is somewhat insufficient, and there are some risks of exposure."

Yes. This Wang Gao is clear.

The air transportation route seems to be hidden, but it is only for small-scale transportation. Once large-scale transportation, it is necessary to consider the consequences of being discovered.

However, Wang Gao did not give up because of choking: “Strengthen anti-reconnaissance methods to keep the airship transportation team in a camouflage state throughout the entire process. Even if it is exposed in the future, it doesn’t matter. I didn’t want to keep it secret.”

This is also his at first. When building the Cloud Realm, why didn't he use the name of the People's Revolutionary Federation, instead of using the Sky Cloud Federation as the vest.

The reason is that in the future, if it is exposed, it will not immediately cause a fierce counterattack by the World Government.

As for whether the Tianyun Federation will be exposed, the answer is definitely yes.

After all, there are not a few Ability Users who have the ability to fly.

For example, the daily suicide Kai Sensei, the "good terrifying" Borsalino, the blind swordsman Issho, the swinging Doflamingo, the big bear who often travels around the world, and the dragon that appears and disappear unpredictably.

These people are all likely to hang around on Skypiea, and the ones who will definitely go to Skypiea are Kay Sensei and Big Bear.

And the person who is most likely to find the Sky Cloud Federation is Issho, because his Kenbunshoku Haki can capture meteorites in outer space with the blessing of many fruits.

Skypiea of ​​tens of thousands meters is naturally nothing difficult.

Therefore, Wang Gao had predicted all this a long time ago. The existence of the vest of the Tianyun Federation is to hide the National Revolutionary League.

There is also the existence of Flying Pirates. On the relevant channels of Skypiea, Flying Pirates and the Sky Cloud Federation are hostile forces.

This situation is mainly to confuse the outside world and reduce some attention.

If people know that the Sky Cloud Federation and Flying Pirates wear a pair of pants, let alone the Great Pirates of New World, even the World Government will have trouble sleeping and eating.

Samael pointed to the Kingdom of Koos in the middle of West Blue: "Now we occupy two of the western sky routes, including the cloud border-the western sky, and Kunlun Xu-the western sky, which is the top of the western sky. A powerful Skypiea, we have not yet completed the establishment of diplomatic relations."

"It doesn't matter, take your time." Wang Gao is not surprised.

The Kingdom of Koos is the giant kingdom of West Blue. In the middle of Koos Island, there is a huge Adam’s Treasure Tree.

This is also the tradition of Giant Race. They planted an Adam’s Treasure Tree every time they visited a new settlement area.

Currently, the four Adam’s Treasure Trees in the world were all planted by Giant Race in the past. However, the Humberion Kingdom and the Tasis Kingdom have been destroyed, and now only the Elbaf and Elbaf of New World are left. The Kingdom of Koos in West Blue.

The two destroyed giant kingdoms, among which the Adam’s Treasure Tree, was occupied by the ordinary people kingdom.

This is also the main producing area of ​​Adam wood on the sea today. Those Adam woods sold for auction are all branches of Adam’s treasure tree.

Of course, for the GFCF, Adam wood is of little value. After all, there are better materials inside, and large-scale artificial Adam wood can also be made through genetic cloning.

Things that are now listed as strategic resources by the People's Revolutionary Federation, only Devil Fruit, N series neutron substances, and strange biological genes are truly valuable resources.

The sky above the Adam’s Treasure Tree on Koos Island is the top of the western sky and the starting point of Skypiea’s western sky route.

Skypiea at the top of the western sky is called Extreme Bliss Island. They rely on the crown of the Adam’s Treasure Tree and have a good relationship with the Kingdom of Koos. They have a very prosperous economy.

Its population is even larger than Angel Island, with a population of more than 30,000. There are even many giants on it who are employed by Extreme Bliss Island.

After the Tianyun Federation secretly inspected here before, it temporarily gave up the idea of ​​contacting Extreme Bliss Island and switched to controlling Skypiea on other routes.

The western sky route was not formed by the existence of Skypiea, but by the high-altitude stratospheric circulation.

For each Skypiea that does not have a global positioning system and a powerful aircraft, it can only rely on this primordial natural airflow to form a route.

This is also why, over the other three Adam’s Treasure Trees, there is no high-altitude route similar to the western sky route, because there is no perennial circulation nearby.

On the seven routes of the West-Tian Airlines, four outs and three ins in autumn and winter, and four ins and three outs in spring and summer.

That is to say, if you take the western sky route and choose the right season of the year, the sailing will double the results for half the effort; if you don’t choose the right season, the sailing will half the results for twice the effort.

Samael went on to explain: "We built three transit sky fortresses in an area about 532 kilometers away from Extreme Bliss Island, bypassing Extreme Bliss Island, allowing the cloud route and Kunlun virtual route. Connected together."

Wang Gao remembered one thing: "By the way, I heard that the meteorologists in Visalia have all joined the Meteorological Institute of the Tianyun Federation some time ago."

"Yes, I personally invited it." Sameer laughed and explained.

Wang Gao is not interested in understanding how Sameer invites each other, he just thought of another thing: "Samaer, you ask them to study the wind direction in the stratosphere."

"Stratospheric wind direction?" Sameer puzzled.

Wang Gao explained: “The altitude from 10,000 meters to ～50,000 meters is called the stratosphere. Now all Skypiea’s are at the bottom of the stratosphere, but in the middle and upper stratosphere, the wind direction and The bottom is not the same."

"so that's how it is!" Sameer suddenly satori.

If the high, middle and low wind directions of the stratosphere are not the same, then in the previous headwind situation, you can adjust the flight height to achieve full downwind sailing.

Wang Gao pointed to the three-dimensional map, the intersection of the bottom layers of the stratosphere, there are a total of 6 nodes, except for Extreme Bliss Island and Windsor Island, the remaining 4 nodes are all without Skypiea. of.

"You have to occupy these four nodes as soon as possible to achieve full control over all parts of Skypiea."

"Understand."

I finished talking about Skypiea. For the high-altitude route, everyone talked about the deep ocean current route hidden in the seabed. This part of the route is also very important.
