Ke Yan People In the World of Ke Xue

A medium-sized bus was parked outside the hotel.

After putting luggage in the trunk.

Iwanaga Chenger drove everyone along the coast in a car, and on the way to the homestay, he introduced:

"...About 270 years ago, during the Edo period, it is said that the underwater palace was still above the sea level at that time, and it was not built by aliens. The evidence is that the scimitar named in the underwater palace was discovered some time ago, and Pistols. Judging from the abbreviations 'M' and 'A' on these two weapons, their owners should be the two female pirates led by Captain Jack Rickman, who were active in 1730, Ann Bonnie and Mary Leigh Reid."

"Oh, I seem to have read a similar story when I was a child..."

Mouri Kogoro wondered, "But I remember that the two of them weren't arrested?"

"That's right, the two of them were imprisoned in the Bahamas prison. Ann, who escaped first, moved the venue to the Pacific Ocean, waiting for the rumors of Mary's escape in front of the pirates..."

Iwanaga Chenger said:

"Later this matter was confirmed, and there was also news that the treasure was hidden on this Divine Sea Island."

"So, the silver tableware found in the underwater palace is real?" Maurilan asked.

"Maybe so..."

Yan Yongcheng did not give a definite answer, "After all, everyone has said this, there should be no mistake."

"What about the underwater palace?"

Mouri Kogoro wondered, "Since it was still at the sea level 270 years ago, is it sinking now?"

"Yeah, you can now look to the left, in the direction of 10 o'clock. Isn't there an uninhabited island over there?"

Iwanaga Chenger continued to introduce:

"It's called Laiqin Island. From it's starting point, continue to the seabed about 200 meters east. A building made of boulders sank, about 10 years ago..."

He briefly recalled:

"At that time, it was rumored that there were diving enthusiasts who discovered historical sites there. Although many scholars have come to investigate, there is still no accurate conclusion on whether the building was formed by man or nature."

No conclusion?

Ye Geng gave a light "ha":

"Eighty percent of the time, it is because of the benefits. After all, it is rare to have a hot topic that can be used as an anchor for the development of tourism. Otherwise, I should really doubt whether those scholars and experts who can't even distinguish artificial buildings are liars. Or tomb robbers in disguise."

"Uh……"

Yan Yongcheng's follow-up words were directly choked back, and the corners of his mouth twitched to tell the truth:

"I think so too, but as the head of the tourism class, I always have to tell the stories to tourists in a bizarre way to facilitate publicity. Otherwise, it will be a big blow to our tourism industry..."

"So, that underwater palace was a ground building from the very beginning?"

Kogoro Mori looked through the glass to the uninhabited island with dense trees.

At this moment, a watch boat crossed their car from one side of the coastline, and they could vaguely see the top of the sightseeing boat. Three or five men and women were constantly taking pictures of the surrounding scenery with their cameras.

"There's no mystery at all..." A certain tool person pouted.

"Cough cough..."

It's obviously the first time Ian Yongcheng has met such a serious guest, and he doesn't dare to use the legendary story with a bit of fantasy to promote it, and continue to introduce the big:

"The part of Laiqin Island that was exposed to the sea in the past was much larger than it is now. It only became what it is now because of an earthquake 300 years ago..."

"Did the earth slide down due to the earthquake?" Conan was curious.

"Uh, yes."

Iwa Yongcheng was startled for a while... It's this child again, he knows a lot.

He paused calmly and explained:

"I heard from experts that there seems to be a so-called methane hydrate layer on the seafloor nearby. Because of the shaking caused by the earthquake, the methane hydrate layer was completely decomposed, so the surface slipped."

"What is a 'fake irrigation hydrate layer'?" Yuan Taiyi asked with a question mark in his head.

Obviously, the female pirate at the beginning, the mysterious underwater building is quite attractive, why after the first brother opened his mouth, all the conversations of several people became incomprehensible content.

Looking around in the car, I found that apart from Dr. Agasa, Haibara Ai, and Conan, the others, including Maurilan and Suzuki Sonoko, also had blank faces.

Ye Gengyi took the initiative and said:

"Methane hydrate, also known as combustible ice. Its chemical formula is CH4·XH2O. It is a clean energy source. Its main components are methane molecules and water molecules. Its formation is similar to the formation process of submarine oil and natural gas. It is probably buried. A large amount of organic matter deep in the seabed is in an anoxic environment, and anaerobic bacteria decompose the organic matter, and finally form oil and natural gas. Most of the natural gas is encapsulated in water molecules, forming "flammable ice" under the low temperature and pressure of the seabed. ". This is because natural gas has a special property, it and water can crystallize at a temperature of 2 to 5 degrees Celsius. Because the main component is methane, it is often called "methane hydrate" because it will decompose into Water and methane, so it just takes enough external intervention to cause a collapse."

"Combustible ice……"

"C...C what 2O?"

"Anaerobic bacteria?"

"Organic matter..."

"Low temperature pressure formation..."

"I still don't understand at all..."

A group of people continued to look blank.

Haha, I just knew... Conan sweated and said subconsciously:

"Brother Geng said it's too complicated, let me just give an example, everyone has played poker, right?"

Seeing everyone nodding, he continued:

"Suppose we build a triangular castle with playing cards, the water molecules represent the playing cards, and then put methane in the gaps between each playing card, so once the temperature rises or the pressure drops, the structure of the castle will change. It's very unstable, and eventually the whole castle collapses and releases methane gas."

"It turns out that, Conan, you really know a lot, but I always feel that my brother's explanation should be more professional."

Mitsuhiko first sighed with emotion, then turned to look at Ye Gengyi with the expression of a little fanboy, and said:

"In the future, I will definitely be on par with brother Gengyi and learn this knowledge well!"

"Well, come on." Ye Geng nodded.

And then became a cadre of a black organization?

Haibara Ai's thoughts wandered a bit, and she coughed hard, reminding the two people in the car to be careful.

"Uh……"

Conan came back to his senses, realized Mao Lilan's gaze, and hurriedly explained: "This... This is what I learned on TV last time."

"Is it a scientific exploration column?" Ye Geng asked.

"Ah? Yes, it should be..." Conan was sweating profusely.

Could it be that you are going to hit Geng Geng's gun today? !

"Ahem...you don't watch TV much at all, do you?" Ai Haihara couldn't help dissecting it.

She didn't want to fight for Conan. After all, the detective's memory of 'love show' is really only slightly better than that of a goldfish.

In this way, before encountering a truly unstoppable danger, it is better to let the first brother teach him a little lesson from time to time...

It's just that the timing is not right, isn't it?

Mao Lilan is now staring at that stupid detective!

Haiyuan Ai was very worried that if the first brother's bad taste was too strong, he couldn't hold it back for a while~www.readwn.com~, causing the guy to reveal his flaws. In order to make up for the loopholes afterwards, it was impossible to use the antidote of APTX-4869 again. Let Kudo Shinichi appear to resolve the crisis.

And according to past experience, at that time, no matter how exhorted beforehand, as long as the forgetful detective returns to his original appearance, he will definitely get carried away and cause trouble.

In the end, it was either that they were implicated together, or that they had to work hard to help them make up for the loopholes again, so don't be too troublesome!

Here, Ye Geng just said "Oh" calmly, saying:

"Oh... that's right, I don't need to learn this basic chemistry knowledge from TV."

Um? !

Conan directly misunderstood and was shocked... Could it be that Gengyi is testing me? !

Haiyuan Ai was also stunned, and hurriedly raised her head to stare at an organization cadre.

In my heart, is this a legend - as long as I doubt him, I won't be suspected by him?

"but……"

Ye Gengyi's unmoved words turned around and said to the two female high school students:

"Knowledge lies in accumulation, and it's not a bad thing to increase memory. Xiaolan, Sonoko, what's your chemistry score, how come you don't even know what methane hydrate is?"

"Ah this..." The two girls sweated in unison.

What should I do if my teacher suddenly checks my homework when I'm traveling...
