Sunday, April 29, morning, Poseidon Island, tourist hotel front desk.

Maori asked the front desk to check in, but the waiter said that there was no Maori reservation, which made Maori very annoyed and couldn't get off the desk.

Lan and Yuanzi stepped forward, one stopped Maori, who was about to get angry, and the other calmly negotiated with the waiter and asked if there was an existing house.

As a result, the hotel was full because of the consecutive holidays.

However, the waiter agreed to contact the Tourism Division and find a way to arrange a room for everyone, and asked everyone to go to the waiting area to rest first.

Maori said unwillingly: "Damn, I obviously have a reservation, but the person said that he had already made a reservation." ”

Dr. Asa smiled, "Okay, okay, it's not a big deal, wait." ”

Lan smiled: "If not, just camp on the beach." ”

"Yes. Ayumi raised her hand.

Mitsuhiko objected, "Well, will the tide rise, camping on the beach, will you drift into the sea as soon as you fall asleep?"

Lan was so embarrassed that she squeezed out her little bean eyes, she really didn't think about it.

Yuan Tai said, "That's not a drifting story." ”

Conan laughed, "It's Robinson." ”

Gray Yuan said, "But they are on a desert island. ”

Yuan Zi smiled evilly, "Ah, this is actually a good way to skip class." ”

Dr. Asasa protested, "Hey, don't teach the kids. ”

"Then why don't you use it?" said Yuan Tai disdainfully.

"I don't skip class. Yuan Zi smiled.

Mitsuhiko said seriously: "No, but we heard that Sister Yuanzi's grades seem to be very bad." ”

"Huh?" the garden was embarrassed.

Ayumi said, "It seems that I can't go to a first-class university on my own." Then he asked, "Really, Conan?"

Gray Yuan is funny, and Conan is dumbfounded, which is tantamount to betraying the mastermind.

"Damn imp. The garden wanted to knock Conan, but he didn't knock, so he hugged Lan and cried, "Lan, how the hell did you discipline your little ghost." ”

Lan laughed and said, "I'm sorry to hold my fist, I accidentally heard Conan when I was on the phone." Then he motioned to Conan to apologize.

Conan had no choice but to apologize obediently, glaring at Gray Yuan by the way, smiling with a gloating face.

At this time, three strong men passed by, their skin tanned.

Conan changed the subject, "Who do you guess they are?"

The garden smiled evilly: "The sunbathing of the sea water is too much, and it has to fight with Hattori." ”

The three people who had already gone far seemed to hear it, and looked back to look this way, but they didn't seem to hear it, and just walked away.

Gray Yuan said, "It should be a treasure hunter, who came for the treasure on the island." ”

Genta asked, "Is there really a treasure?"

Mitsuhiko said: "If you get your hands on the treasure that sleeps in the sea, you will become a rich man." ”

"Don't dream, will there be treasure waiting for you?" said Maori, angrily, "someone has already picked it up." ”

Ayumi asked, "But, how did you know that they were treasure hunters, because they were dark-skinned?"

Conan replied, "If you look closely, although those people are very tanned, they are not so dark except for the palms and heads, which means that they are often wearing wetsuits, and the color of their hair has faded from the sea." ”

Mitsuhiko questioned, "But if that's the case, maybe they're just people who like diving, right?"

Conan said, "But ......"

Gray Yuan preemptively said, "You don't want to say that because of the treasure posters on the island, do you? So strong men like them should be treasure hunters, not diving enthusiasts? Or are all diving enthusiasts treasure hunters? Are you reasoning?"

"Uh......" Conan was speechless.

Yuanzi smiled: "Ha, this dragged four-eyed imp has also met an opponent." ”

"Garden. Lan said, "Conan is still young. ”

Dr. Asa winked at Conan, well, Conan is indeed still young.

Conan raised his triangular eyes, "Grayplain, then you say, why do you think they are treasure hunters?"

"Feeling. Gray said bluntly.

"Huh?" Conan fell directly, and after a long time like him, he was actually a detective's intuition, but he didn't dare to say it.

Yuanzi and the others laughed, and Lan laughed while helping Conan up, but Conan was even more embarrassed.

Gray Yuan chuckled, in fact, she saw what they said, read her lips, and this could not be said.

At this time, a slightly fat middle-aged man with glasses hurriedly ran into the hotel, ran over, and then didn't wait for the mouth to speak, and first came to the ground.

Sonoko said with a smile: "I feel like I see the main hall." ”

"Don't laugh at people. Lan couldn't help but laugh.

The middle-aged man got up and introduced himself, "You are the famous detective, Mori Kogoro, right? Welcome to our island, I am the head of the island tourism section Iwanaga." ”

"Ah, it's you, I remember your voice," Maori cried, and then to the crowd, "and he was the one who told me to book a stay." ”

"Yes, it's me. Section Chief Iwanaga said.

Maori said angrily, "Damn, my room." ”

"Well, because of the continuous holiday, in fact, there have been a lot of tourists booking since two months ago, and when you book, there are not many rooms in the hotels and hostels on the island, and it is really difficult to arrange for your group of seventeen people to stay in a hotel or inn. Section Chief Iwanaga smiled, and then sighed, "Although everyone is busy, they are all happy, and they are counting on the tourist season to make money." ”

Maori said angrily: "Don't tear me off. ”

"Yes, yes, I was about to say, I was about to say. Section Chief Iwanaga smiled and said, "After my hard work, I still helped you find a suitable hotel, which will definitely allow everyone to stay, please come along, and I will drive." ”

Maori said, "If you dare to lie to me, I will definitely complain about you." ”

"Yes, yes, please, everybody, please. Section Chief Iwanaga wiped his sweat, "Hey, why are there only nine?"

Lan said, "Oh, they're coming over one after another, and we'll call, so you won't have to bother." ”

"It's okay, what I should do, call me anyway. Section Chief Iwanaga hurriedly took out his business card and handed it over, "I'm sorry, I just wanted to get a business card, but I fell and forgot about it." ”

Yuan Zi said to Lan Sha'er: "It's not good, this hall is the template for this guy when he grows up." ”

"Uh......" Lan couldn't imagine that Hondo Yingyou was middle-aged and would look like this fat, no, fat.

Conan, who overheard their conversation, imagined that a copy of Tang Yingyou would become a middle-aged man, with a round face and a pair of phoenix eyes, a little chilly.

Conan grinned, followed behind the group, and walked out of the hotel with Iwanaga Division, and went to a solar-powered sightseeing car in front of the sightseeing bus he drove on the side of the road.

Wiping his sweat, Section Chief Iwanaga explained, "Well, we have been advocating energy conservation and reducing emissions on the island to maintain a good environment so that tourists can enjoy high-quality air. ”

"Sitting in this car, you can breathe in the romantic atmosphere of the sea and visit the beautiful scenery of the island all the way. ”

Maori sighed: "You don't lose the tourism class, you can really say." ”

Yuan Zi said angrily: "Now the price of refined oil is relatively high, and this island is far away from the mainland, because of the inconvenience of transportation, the price of refined oil is higher, and the funds are not enough, just say it, you have to play the banner of environmental protection." ”

Gray Yuan said: "Forget it, it's quite fresh to sit once in a while." ”

Ayumi smiled, "Well, it's really fun. ”

"It feels like a bumper car," Motota said. ”

Mitsuhiko said: "I just don't know if it's safe or not, can I get on the road." ”

Dr. Asa laughed, "It should be fine here, there are no cars on the island." ”

Section Chief Iwanaga said embarrassedly, "Come, please get in the car and be careful about bumping into each other." ”

At the invitation of Section Chief Iwanaga, everyone got into the car, and except for Dr. Agasa, who was a little uncomfortable sitting because he was too big, everyone else felt fine.

As the sightseeing bus started, Section Chief Iwanaga also opened up the conversation, "Detective Maori, you're here for the treasure too, right?"

"Is there really a treasure?" Lan diverted the subject, lest Maori open his mouth to drink.

"I guess it's true," said Section Chief Iwanaga with a smile, "I found silver cutlery in a palace under the sea more than two weeks ago. ”

"Really?" Motota, Ayumi, and Mitsuhiko suddenly became excited.

Yuan Zi asked, "Is the underwater palace the ruins of the sea that are rumored?"

Section Chief Iwanaga said, "That's right, on the small uninhabited island of Yorikinjima, a kilometer southeast of the island, there is a sunken boulder building on the seabed two hundred meters east of it. ”

"In the 70s, the island hired the otome ocean exploration ship to use the deep-sea diving survey vessel Boundary 600, which was still called the Boundary at the time, to survey the fishing around the island, and at that time, it was discovered that there were ancient ruins there. ”

"At that time, there was a craze in the academic community, but due to technical conditions, there has been no conclusion as to whether it is man-made or naturally formed. ”

"At that time, many people came to hunt for treasures, but the technical conditions were not good at that time, and after many people died, they calmed down. ”

However, scholars and treasure hunters have driven the island's economic development, and there are many diving enthusiasts, and through their casual publicity, Poseidon Island has gradually become a diving destination. ”

"At that time, the domestic economy was getting better and better, and Poseidon Island was developed little by little, and it slowly became a resort, and in the mid-to-late eighties, the island could be said to be overcrowded during the tourist season. ”

Maori said: "Don't talk about your tourism history, just talk about treasures." ”

Section Chief Iwanaga smiled, "Don't worry. ”

"In the 80s, the marine survey ship Kirishima came and let the deep-sea diving survey ship Boundary 2000 go down to explore. ”

"It is said that the area was still on the sea 300 years ago, and it is also confirmed that the ruins are a mountain peak, not a man-made structure, but there are traces of artificial excavation. ”

"At that time, some sailors' objects were found in it, and it was proved that they were modern objects, objects from the mid-to-late 17th and early 18th centuries, and the sailors had carved out the mountain just to create a shelter from the wind and rain. ”

This result is equivalent to a basin of cold water, which directly extinguishes the enthusiasm of most scholars. ”

However, for the treasure hunters, this result only made them more enthusiastic, because it was arguably the golden age of piracy, and they suspected that it was a secret base for pirates. ”

"There were a lot of treasure hunters who went to investigate, and dived into the sea to get to that cave, but there seemed to be some mechanism in there, and those who went in either came back or never came back. ”

Maori said angrily: "Isn't this nonsense, those who don't die will definitely come back." ”

"Don't interrupt," asked the garden, "what happened?"

Section Chief Iwanaga smiled, "Later, the Yokosuka Marine Survey Ship came with the deep-sea diving survey ship Boundary 6500 to conduct further surveys and draw more detailed charts.

"In the past, Raijin Island was much larger than it is now, and it is said that it was possible to walk to the main island during low tide periods. ”

"It is speculated that the earthquake that occurred off the main island of Ogasawara in January 1826 caused a change in the methane hydrate layer on the seabed, causing the entire island to sink to the bottom of the sea, and it is believed that the earthquake caused a huge wave of more than 6 meters high in Futami Port on Chichijima. ”

Dr. Asa smacked his lips and said, "It was a terrible earthquake, but luckily it was an uninhabited island at the time. ”

Mitsuhiko asked, "What is the methane hydrate layer?"

Conan replied: "In a low-temperature and high-pressure environment, water molecules combine with methane to form the so-called water cage structure, which can also be called combustible ice. ”

Gray Yuan is speechless, what grade are you?

Yuan Tai was puzzled, "Combustible ice?"

Ayumi didn't understand, "Water cage structure?"

Conan continued: "Figuratively, everybody has a castle covered with playing cards, right? Water molecules are hollow castles like that, each cell is filled with methane, and when the temperature rises or the pressure drops, the castle collapses and releases methane gas. ”

"I see. Motota, Ayumi, and Mitsuhiko said as if they didn't understand.

"So the island, which was originally on methane, will lose its support and cause the surface to slide down," said Yuanzi. ”

Section Chief Iwanaga smiled: "Wow, this kid is really amazing, and he explains it better than me." ”

Conan was braked, and a cold sweat broke out.

Gray Plains is funny, big fool, look at how you lie.

Conan turned his head to face Maori and Lan, "That and that, I introduced it on TV last time." ”

"Well, let's just say you don't forget it. Maori said angrily, and then pondered, "Hey, next time, I just took you to the competition, maybe I can win the prize." ”

"Daddy," Lan was dissatisfied, "you can think so." ”

Maori said confidently: "What, this kid eats me and lives in me, if you have the ability, you should contribute, who told you to help him save all the foster care money given by his mother." ”

Lan said angrily: "The one who can spend money the most indiscriminately in our family is you, Dad, and what you spend on Conan is only a fraction of what you use indiscriminately." ”

Conan nodded again and again, what he said was so right, all of them were given to others, mahjong parlors, horse farms, small steel ball shops, nightclubs, etc.

Maori was depressed, and he was unwilling to find a reason to retort, "That's because he's still young." ”

Lan said confidently: "It's because of his young age, so he has to save it even more, who knows what the price will be when Conan grows up, how much this money can help Conan reduce the burden of starting a family." ”

"Poof. Dr. Asa couldn't help laughing, laughing in his heart, Conan's family, Lan, you have to cooperate a lot.

Conan is a waterfall Khan, and Lan is thinking too far.

Gray Yuan simply didn't look over, laughing a little guilty, he had to divert his attention and relieve it.

"Alright, okay, let's talk about your housework when we get home, and now let's continue to listen to the story. Yuan Zi smiled. ……
