Heaven’s Gate

"Altitude sickness occurs when a person travels to a high altitude without gradually acclimatizing. It is most prevalent at 8,000 feet or higher and results from a shortage of oxygen."

"Altitude sickness? But we three are fine?" Zoro said.

"You guys are fine because of your overall body capability is on abnormal level, but them are a different matters,"

"Altitude sickness results from a rapid change in air pressure and air oxygen levels at higher elevations. You may have symptoms if you travel to a high elevation without giving your body time to adjust to less oxygen. Even if you're physically fit, you can still experience altitude sickness"

Xin command to enclose the whole ship with a barrier to prevent the symptoms from becoming worse, he then changes the air inside into normal flow.

After that, the others start to feel relief, some are still feeling dizzy and have shortness of breath.

Chopper, who recovers fast, starts checking everyone's condition. Except for Usopp and Vivi who have severe symptoms, everyone is fine.

Xin helplessly looked at Nami and said," If you train diligently, you will not experience this, you can easily change the flow of air if you want."

"Well….. It's boring to meditate everyday… so…"

"O your lazing around? Did Nojiko do the same as you?"

"No, Nojiko and Bellemere are diligent in their own training. I'm the only one who…. Well... you know." Nami embarrassingly said while cutely sticking out her tongue.

"You're good, you need to punish, I want you to control the wind around the ship until everyone gets used to the high-altitude atmosphere.

"Okay." Nami hurriedly nodded.

Xin removes the barrier then lets Nami control everything, he then walks on the side of the ship while looking around.

"So where are we going next Xin?" Zoro asks.

"Don't know, this is my first-time coming here so I don't know where we are going next. Let's wait for others to recover first before moving away from here."

"Okay."

"By the way, it's pretty clean here, the whole palace is really white."

"But still, out ship actually on the top of the cloud,"

"We are sailing on clouds."

"Of course we can sail on top of it, they're just a cloud." Luffy idiotic said.

"No! It's impossible," All of them.

Nami, who finished adjusting the air around, walked beside Xin and looked around," So this is the Sea of the Sky."

"But Nami-chan, the Log Pose is still pointing up." Vivi said.

"Maybe this is only the middle part of Sky Island?"

"So we need to go higher? Can we go back? I feel that we will die if we go higher," Usopp, who just recovered, said.

"Don't worry, Nami is adjusting the air right now so you guys will not experience Altitude sickness anymore."

While everyone is thinking the next step, Xin. Usopp, Luffy, and Chopper on the other hand are sitting on the end of the ship.

"Do you think we can swim to the sea of clouds?" Usopp idiotic ask.

"Of course, this is a sea right?" Luffy said.

"Don't know."

"Don't try it, we are above the clouds, if you ever try to swim downwards, you will fall below to the blue sea and die for sure." Xin said.

"How did you know?"

"You guys don't remember? We enter the cloud and we did not encounter any solid object when we arrive here, that means the there's no ocean floor on this sea,"

"What about fish? Sea monster?" Luffy asks.

"There is." Xin points to the cloud and sees a gigantic shadow swimming around them right now.

"Kyaaa!! Monster!"

"Meat!"

Before they even stop Luffy, he already pulls a gigantic strange-looking fish with a sharp row of teeth.

"Waaaa!!"

"Nothing to be scared about." Zoro and Sanji then made their moves, they started to beat all the monsters around them until nothing left.

A few minutes later, the ship is now full of strange-looking fish, while Nami is beating Luffy because of his idiotic idea.

"This is a weird-looking animal, I wonder if they are still considered a fish?"

"That octopus was like a balloon."

"This one is still moving even though it's already dead."

"What's this? A flat snake?"

"It's a flatfish because it's flat."

"So this is a flatfish."

"Better to call it ocean than cloud,"

"This may be Sky Fish from Olman Cricket's book right?"

"Okay that's enough, lets go that way, i feel that we can find the right path if we go that way." Nami said.

"What's that? It looks like a waterfall to me."

"Yeah, and that cloud looks weird right?"

An hour of sailing made them arrive at the Heaven's Gate, the entrance of the Sky Island.

"They have an entrance too? That's weird."

"Yeah,"

"Look, there's a person, let's ask her."
