From Impel Down to the Multiverse

After a while.

A huge airship appeared on the side of the tree top.

Wang Gao took Mamen, Asmode, and a group of ghost shadow soldiers who were responsible for driving the airship, and took the airship to high altitude.

Clouds and mists are lingering, and the visibility around is less than 100 meters.

Until the airship breakthrough a certain limit, everyone felt a dazzling rays of light, and then they saw an endless blue sky, and below the airship was a white sea of ​​fog.

This is the White Sea at an altitude of 7000 meters.

To be precise, this is the condensation cloud formed after water vapor encounters the high-altitude cold air, not the real White Sea.

Because of the formation of the White Sea, there must be a prerequisite, that is, a special keratin particle erupted from the underground volcano will form the "sea cloud" in the White Sea after combining with the material in the cloud. "Island Cloud".

Wang Gao has separated that special particle-N hydrogen, or neutron hydrogen, through the deep roots of the Wuhai tree.

It can combine with water molecules to form a special cloud with super buoyancy.

The sea of ​​clouds formed by the sea of ​​fog trees above the Devil’s Triangle Sea Territory does not actually contain N hydrogen. Therefore, the sea of ​​clouds here is just an ordinary sea of ​​clouds. Ordinary ships cannot float on it and can only use airships. Come up.

This airship was also built by Wang Gao using hydrogen N particles. It can use the super buoyancy of hydrogen N particles to achieve ascent and descent and flying in suspension.

Lucifer has collected the molecular structures of sea clouds and island clouds from other Skypiea through the shadow world.

When the airship rises to an altitude of 10,000 meters, it is empty here, and there is no Skypiea formed by island clouds.

In fact, the formation of White Sea and White White Sea requires the help of volcanic eruptions, preferably active volcanoes that erupt frequently.

Otherwise, Skypiea would not be so scarce.

Wang Gao instructed: "Asmod, let the black mist emit water vapor with all its strength."

"Yes, Father God." Asmod is nodded.

In a short while.

Mist Sea Tree—The black mist crazy absorbs the surrounding sea water, and then produces a large amount of water vapor, but the air vent on the top of the tree has changed its shape, from the previous honeycomb shape to a single big hole.

It's just that the large pores are closed at this time. As time goes by, the water vapor in the body of the Wuhai tree is increasing, and the pressure is also increasing.

Finally, the steam pressure breaks through the big hole to withstand the limit, and it bursts out in an instant and hits high altitude.

After the precise calculation of the eruption pressure, the water vapor successfully reached an altitude of 10,000 meters, and then spread to all directions.

The airship immediately launched a large number of rockets. These rockets exploded in the steam mass and released a large amount of hydrogen.

After the successful fusion of water vapor and N hydrogen, an island cloud material is formed.

Three days later, a piece of Skypiea with an average thickness of 300 meters and an area of ​​300 square kilometers formed at an altitude of 10,000 meters in the Sea Territory of the Devil’s Triangle.

Wang Gao named this place "Yun Jing".

On the other side.

The Red Line continent between South Blue and West Blue, in the Antarctic Circle, which is frozen all year round, looks like a calm and tranquil area.

Actually, Lucifer opened the shadow channel on the Red Line continent under the ice sheet, while Mammon used the ability of the spar base to extract the rock crystal material of the Red Line continent on a large scale. Come out, and then stuff it into the shadow channel.

Lucifer carried the stuffed crystal material to the cloud boundary.

When the crystalline matter carried reached 50% of the load-bearing capacity of the cloud realm, the two men stopped drawing the crystalline matter.

Mamen returned to the cloud realm, looked at the mountain of crystal matter, took out a design drawing prepared in advance, pressed one hand on the design drawing, and the other on the crystal mountain. Immediately start the ability.

Countless crystalline substances began to change, forming the buildings on the design drawings in the cloud environment.

First of all, it is the Sky City in the center of Yunjing, which is a city like concentric circles.

Then there are four airport cities, namely Donggang, Xigang, Nangang, and Beigang.

In the future, these ports will serve as the home ports of the National Revolutionary Air Force Battleship team, air transport ships, and air merchant ships.

Then form the buildings, roads, sewers, etc. inside the city, and then the road network and railway network connecting the five cities.

Finally, it is the key part of Ladder City.

In the concentric building layout of the ladder layer, the buildings are concentrated in the outer circle, and the inner city in the center is not actually used for living.

Mamen constructed four cables here. The whole body is composed of carbon nanotubes. The four cables extend downward from the inner city and then connect to the Wuhai tree.

However, it is not connected to the top of the tree, but to the tree waist about 2000 meters high, where there are four specially modified platforms and a circular channel.

The tree waist platform is connected to the area near the sea surface, the internal base and the like through the elevator shaft.

Mamen is busy transforming the ladder.

Wang Gao arranged the remaining large vacant land in the cloud environment, such as the vacant land around Beigang, which was used as an industrial area.

The vacant land around Donggang is planned as a farm.

The surrounding area of ​​Nangang serves as forests and lakes.

The air force training ground is set up around Westport.

At the same time, Lucifer also began to secretly take in some refugees in various war-torn areas, and through the shadow channel, they were placed on the food island and the cloud environment, and a small part was allocated to the black reef islands.

After Wang Gao completed the construction of Yunjing, he took Asmodeus and took an airship to Skypiea-Birka, which is 836 kilometers away.

The speed of the airship is not fast, but the airship that uses N hydrogen as buoyancy is not the same as the conventional hydrogen airship. The same volume of hydrogen and N hydrogen are at the same temperature and pressure. There is a 12.4 times difference in buoyancy.

Therefore, the load capacity of the N hydrogen airship is very large. The airship that Wang Gao rides has a maximum load of about 8,500 tons.

In the airship, all kinds of living facilities are readily available, and there is also a small laboratory in it.

Flying at an altitude of 10,000 meters, looking at the clouds and blue sky below, there is a natural tranquility in the whole person.

Suddenly, Wang Gao's gaze condensed, as if penetrating through the stratus clouds, he saw a small island on the sea surface of the Grand Line.

A Marine Battleship is docking on the side of the island.

The giant Marine officer, looking at the white-haired woman in front of him, waved his hand expressionlessly: "Shoot away."

The white-haired woman was very painful, and she suffered the death of her companion. Sadness, the frustration of being unable to continue studying Poneglyph, and worries about the hometown.

Several Seaman put handcuffs on the hands of the white-haired woman and put them on the Battleship.

High in the sky, Wang Gao, who used Kenbunshoku to see this scene, did not mean to save the other party. The main reason was that he saw the inside of Battleship and there were several CP organizations.

It's not that they are afraid of these people, but two of the CP members. In Lucifer's intelligence data, they are the people who own Kenbunshoku Haki.

It is still quite difficult to quietly rescue people in front of people who are proficient in Kenbunshoku Haki.

Wang Gao does not want to overstimulate the World Government for the time being. Poneglyph is precisely the opposite scale of the other party. It is estimated that the destruction of Ohara has entered the countdown.

That Marine Battleship, I don’t know at this time, I accidentally escaped, and is sailing in the direction of Judicial Island.

Wang Gao’s airship also continued to head towards Skypiea Birka.

On the other side, undercurrents are also surging in Impel Down.

With the three old men of Columbus, one died and the other retired from injury, the cursed fruit of Della was also seconded by the CP organization on January 7, 1500.

Although Magellan and Shiliew of the Rain and the others strengthened their own training after the last Bearman Boomer incident, their strength did not increase explosively.

At this time, Hancock is the mainstay of Impel Down.
