One Piece: Arrival on Sky Island at the beginning

“Sea levels are rising!?”

Olvia's words confused both Dorag and Shanks.

Although the two of them are both top-notch in terms of strength and strategy, if you want to talk about science with them, you may be a little bit over the top.

Seeing this, Olvia also thought about it and said it differently.

"Let's put it this way, if nothing is done, it will only take less than 1000 years for all the land and islands in this sea, except the Red Earth Continent, to be submerged by the sea!"

Now both of them finally understood.

"Is this a bit too exaggerated?"

Dorag asked with some confusion. Although 1000 years is a long time, it only counts more than a dozen generations. Now Olvia's words are not talking about 1000 years later, except for red clay. Apart from the mainland, other worlds will be destroyed?

As if she knew what Dorag was thinking, Olvia said with a smile.

"Don't worry! Although the sea level is constantly rising, the world will not be destroyed in 1000 years, not even in years."

These contradictory words made both Dorag and Shanks feel a little strange.

"why?"

Olvia didn't say much nonsense.

"It's simple, because that's on the premise of doing nothing. Based on our exploration of historical texts and ancient ruins, we found that this world has a unique system that can prevent this kind of thing from happening."

After finishing speaking, Olvia looked at Shanks and asked a question.

"Mr. Shanks, have you followed Captain Roger to Lough Drew?"

Shanks shook his head and said in memory.

"Unfortunately, due to some special reasons, I chose to disembark halfway."

"That's a pity. If that's the case, let me ask another question."

Olvia said, looking at Dorag and Shanks and asked another strange question.

"Both of you must have been to Upside Down Mountain and Fish-Man Island! You must be deeply impressed by the strange ocean currents there!"

Drago and Shanks nodded naturally.

At this time, I heard Olvia continue to ask.

"Then, have you ever thought about why there are such strange ocean currents that can cause the sea to go against the laws of nature, rising from low sea level to such a high place like an upside-down mountain, and rising like a fish-man island? What about sending the coated ship to the bottom of the sea and passing through Fish-Man Island to enter the new world?"

The two of them really couldn't answer this question.

Dolag also said unceremoniously.

"If you can, please tell me the answer!"

"Of course, but this is just our speculation."

With everyone watching, Olvia slowly revealed O'Hara's final findings after so many years of archaeology.

"Actually, the answer is very simple. We speculate that at the end of the new world, somewhere under the sea, there is a huge cave..."

"Huge cave!"

This was something neither of them expected.

"correct!"

Olvia seemed worried that she couldn't explain clearly, so she used her hands to sign.

"This cave is very big, incredibly big. The sea water from the sea pours into it through turbulence, triggering the huge ocean currents that create the entire Grand Route. Generally speaking, the sea water from all over the world pours into the Grand Route through the Upside Down Mountain, and then flows through it. The passage beneath the Holy Land of Mary Gioia, into the New World, and finally into this huge cave.”

"But this cave will eventually be filled up one day!"

Shanks asked confused.

"Unfortunately, no..."

"Hey!!! Is this cave actually that big?"

Olivia shook her head.

"It's not that this cave is very big, but there are other reasons. You can simply understand that this is a cave that will never be full. The reason is also very simple. Because this cave is deep underground, it is already very full. The magma is close to the center of the earth, which causes the bottom to be extremely hot. When cold seawater is injected into it, the alternation of cold and heat will produce a large amount of hot air. As more seawater is injected, this air will also The more it will, until it reaches the limit, an explosion will occur, and the huge pressure will expel all the air and water inside the cave..."

Almost subconsciously, Shanks and Drago thought of something, and said with bright eyes.

"Dr. Olvia, are you talking about the strange rising currents in the sea?"

Olivia smiled and nodded.

"That's right, that's it. The rising sea current will erupt the seawater and steam in the cave to tens of thousands of meters or even higher into the sky. During the explosion process, the high pressure of the explosion will condense into a unique island cloud. Among them, The heaviest seawater will turn into rain and fall back onto the sea, while the island clouds will remain at an altitude of 10,000 meters. This is the reason why sky islands in our world exist, and the lightest air will be ejected to an altitude of 10,000 meters. This is why there is air in the outer space of our world, including where the moon is."

This was an answer that definitely surprised Dolag and Shanks, and they could say that they had gained a lot of knowledge.

This makes them seem to completely understand some of the rules of how this world works.

Olvia continued.

"After cooling, seawater will continue to pour into it, so that we can use the perfect cycle of the power of the planet under our feet to solve the problem of rising seawater. The existence of the windless zone is also for this reason. It is composed of the four seas and the great A shipping route is just an intermediate ocean current sandwiched between two completely different ocean currents."

Dolag took a long breath of air and said.

"In that case, doesn't it mean that there is no need to worry about the problem of world destruction caused by rising sea levels?"

Olivia shook her head solemnly after hearing this.

"No, in fact, we have to worry instead."

"Eh!!!"

Shanks and Drago were confused again.

Then, the two heard Olvia say terrible words.

"Because through our scientific investigation, our world has experienced two sea level surges..."

"twice!!!"

"Yes, these two sea level surges almost destroyed our world each time."

At this point, Olvia's topic finally came to the final answer.

"However, fortunately, during these two world crises, we met heroes who saved the world."

"During the First World Crisis, the hero we met was a legendary warrior called Nika..."

"And the second time, the name of this hero should be familiar to you. He is the man called Joey Boy..."

"And the reason why we have to worry is because the thing that almost destroyed the world twice was the terrifying power known as the national treasure of Holy Land Mariejoia..."
