Conan's Kingsman

"Then everyone, come with me, I will take you to the hotel... Oops." Mr. Iwanaga finally wiped the sweat and dust off his face, and when he was about to take people to the car, he accidentally bumped into someone from the building.

One of the three strong men who came down.

"Who are those guys?" Uncle Maori couldn't help but asked when he saw the three strong men looking very troublesome. "I think they are treasure hunters, right?" Conan said with a smile, and now it was him again.

It's time to perform. "Treasure hunter? What is that?" Yuantai asked with a confused face. "Treasure hunters are those people who travel around the world looking for treasures." Hoshino Kaede explained with a smile.

"But how do you know?" Haiyuan Ai asked. "You see, although those people are very tanned, the parts from their wrists up are not that dark, right? And their hair has also been damaged due to long-term

If it becomes discolored after being soaked in water, that is proof of long-term diving." Conan explained.

"But what if they just like diving?" Mitsuhiko retorted. "That's common sense, but as long as you see that poster, I think anyone will think that they are treasure hunters, right?" Hoshino Kaede interjected.

, pointing to the poster on the side. "Yes, they are also looking forward to it, hoping to get the legendary treasure sleeping in the sea."

"It sounds so nice, but they are just local dogs looking for food." Hoshino Kaede lowered his head and whispered in Haihara Ai's ear. "Oh? It seems that someone has dealt with this group again?"

Yuan Ai smiled slightly. To her, Hoshino Kaede was like a treasure that could never see the end. Every time he mentioned something new, it seemed as if there were no secrets in front of this guy who had traveled the world and licked blood.

.

"That's not true, I just heard about these guys." Hoshino Kaede said, "After all, this is just a bunch of stupid thieves who are making small fuss. Most treasure hunters are idiots and have no skills. A more advanced person would be more capable.

It’s very big, but it’s not like you’d be reduced to stealing this so-called undersea palace.”

"Which one is more advanced?" After getting in the car, Conan also came over and asked. He was quite interested in this kind of thing. "Oh, I heard about it too. Do you know about the Battle of Thermopylae? Column

Oneidas led 800 Spartan warriors to angrily attack Xerxes' 100,000 troops. It is said that a guy dug out the spear that Leonidas used. I heard that it was not rusty yet.

"

"This guy is awesome!" Conan exclaimed. "Ahem, it's a sister. I heard she's a girl. It seems that after she dug it out, she sold it to any consortium and became rich overnight." Hoshino Kaede said,

"So, any hunter who can take a fancy to the treasures of this so-called underwater palace is either a big shot who wants to make a last buck and retire, or a fool who is half-empty and tinkling bells."

"Eh? Why do you say that?" Haihara Ai asked curiously. "Because this is the Okinawa Islands. Before modern times, it could be said to be a very poor place. Where did the people in this place get the money to build palaces? And they

The population does not support them in building such a huge building complex. When Egypt built the pyramids and China built the Great Wall, hundreds of thousands of laborers were used to build it for many years. No ruler would build a house that he would never use in his lifetime, right?

"

"Of course, I heard that Queen Himihu of Yamatai Kingdom seems to have some mysterious power. She may have built it." Hoshino Kaede didn't say too hard. After all, there are too many unsolved mysteries in the world, even the human pyramids.

We haven’t figured it out yet, and no one can say for sure whether this underwater palace was built artificially or formed naturally. But there is definitely nothing valuable here.

"Hey, hey, aren't Himiko and Yamatai a fairy tale?" Conan complained. "Who said that? That's something recorded in the Three Kingdoms. You Japanese haven't even read the Three Kingdoms? I remember that the culture of the Three Kingdoms is not

Very good in Japan

Is it popular?" Hoshino Kaede gave him a strange look. "Well, this is true. The Wei Zhi part of the Three Kingdoms is indeed recorded." Haihara Ai nodded. She had been studying Chinese culture for a long time.

It can be said that he is half a master of China.

"By the way, why would treasure hunters come to this island?" Uncle Maori, who was sitting in the passenger seat, asked while admiring the scenery. "Well, it's because the treasure was discovered two weeks ago." Mr. Iwanaga said lightly. "

So the silver tableware found in the Undersea Palace is real?" Xiaolan said in surprise. "That seems to be the case."

"What is the underwater palace?" asked Uncle Maori. "Look, isn't there an uninhabited island over there?" Mr. Iwanaga pointed to the island not far away and said. "That's Norichijima Island. From

There, two hundred meters to the east on the seabed, sleeps a building made of huge rocks. There have been rumors about ancient ruins near Shenhai Island since ten years ago. Although many scholars have investigated it, what exactly is it?

Whether it was man-made or natural has not yet been determined."

"I heard that the part of Norichijima Island that was exposed to the sea was larger in the past, but it sank to the bottom of the sea three hundred years ago due to an earthquake, and it became what it is now." As the boss of the local tourism section, Mr. Iwanaga has a natural understanding of the origin of local attractions.

He knows it very well and can explain it very clearly casually. "You said it sank to the bottom of the sea because of the earthquake? Did the surface slide occur?"

"Yes, I heard that there seems to be a methane hydrate layer on the seabed nearby. The vibration of the earthquake caused the methane hydrate to decompose at once, causing the surface to slide," Mr. Iwanaga explained.

When Conan heard this, he sat back in enlightenment, looking like he was deep in thought. "Hey, Conan, let me ask you, what is a false hydrate layer?" Yuantai asked. Beside him, Sonoko and

Ayumi looked at Conan with confusion. "Oh, that's called a methane hydrate layer. In a low-temperature and high-pressure environment, water molecules will mix with methane to form a so-called water dragon structure. Some people also call this phenomenon

Combustible ice."

But even after explaining it this way, the three of them still looked confused. "Well, let me put it another way." Conan thought for a while, "You must have built a house with playing cards, right? It's probably like that with water molecules.

After leaving the castle, each room in the castle is filled with methane gas. After being stimulated by the vibration, the gas will escape and the castle will collapse."

"Look at the great detective explaining a solid gas so profoundly, Xiaolan doesn't doubt that there is something wrong." Hoshino Kaede smiled softly. "Ahem." Haiyuan Ai rolled his eyes and coughed twice to remind him of the pretense.

The over-exerted detective.
