On Sunday, August 17, at around 3:00 pm, a fishing holiday home on Izu Beach. "Ke*le*yan*love*shot*fast*fast()"

Kasuhiko Kasuhiko put down the four members of the detective group, and then Ran and Yuanzi drove away. As soon as Ran and Yuanzi and others walked to the holiday house, they found that Maori was coming happily with the fishing gear.

"It's just right, come and see, this is my harvest." Maori opened the big box containing the fish, one meter long, half a meter wide, and thirty centimeters thick, revealing a box of fish full of them, with more than a dozen, and a layer of ice underneath.

"Wow!" Lan, Yuanzi and others shouted in dismay.

Maori asked proudly: "How is it, am I very powerful?"

This seems to be a stone carving fish? Conan is very confused. Since he didn’t go to the beach, how could he catch deep-sea fish?

Yuanzi said: "It's so amazing. How many fish are there in just over an hour?"

Yuan Tai shouted: "Uncle, uncle, can you take us to fish?"

"No, no, I promise to keep it confidential." Maori smiled, "Anyway, you're ready to eat." As he said that, he put the fish box together, then put the fish box into the car, and left with beer and another fish box.

"Really, forget it, let's play volleyball again," said Yuanta. "I tied yesterday, and I must decide the winner today."

"I won't go." Yuanzi said.

"So too, you guys go by yourself," Lan said, "Don't run too far, don't take off your body jacket."...

After playing at the beach for half an hour, the four of them suddenly found a drift bottle floating over. Conan used his folding knife to cut the drift bottle open.

When the four of them saw the letters inside the drifting bottle, they were immediately shocked. The cover of the bottle was engraved with the words "sos, ninja" on it. It was the letter of help from the Matsuki Ninja. It seemed to be carved from the nails.

Mitsuhiko asked, "Does this ninja mean the ninja sister just now?"

Azumi asked, "Why would Sister Nin write this?"

Yuanta said: "It's still floating from the sea."

"I don't know if Brother Haruhi is back, let's go back and ask." Mitsuhiko said.

The four of the detective team returned to the fishing holiday house and found that there was no one inside. They asked the boss. It turned out that Haruhiko had returned the small yacht and diving equipment more than ten minutes ago. Then they chatted with Ran and Yuanzi for a while before leaving with them.

"What should I do?" Azumi said, "If it was really what Sister Ninjae wrote, it would be bad."

Yuanta said: "Okay, now is the time for our youth detective team to go out."

"But where to investigate?" Mitsuhiko said, "If Sister Ninjae is on which desert island, it would be too far away."

"There are only a dozen minutes in between. She can't go too far in such a short time." Conan said, "Just just now, I saw an old man cleaning up the garbage by the sea. He must know the direction of the current nearby, so that he can know which direction the bottle came from."

"Then let's go quickly." Azumi said.

"Wait, bring the rubber boat with you," Conan said.

"I'll do it." Yuan Tai said...

A moment later, the four of the detective team found the old man who cleaned up the garbage. Under his guidance, the four of the detective team walked east along the beach.

Not long after, the four members of the detective team found that Moritsuki Nin was lying motionless on the rocks in a cave by the sea, but due to the high tide, there was no way past.

Yuanta immediately cheered up the rubber boat, and then carried Mitsuhiko, Ayumi and Conan over with the rubber boat.

The detective team woke up the Hokutsuki Ninja, "It's so great."

"It's you." Wangyueren said powerlessly.

"What happened?" Conan Fu Wangyue Nin sat up.

Azumi asked, "Why are you here, Sister Nin?"

"Huiyan said he wanted to take me to a place I hadn't been to dive. He said it would disappear into the cave in the sea when it was full of tide." said Makoto Ninja. "Later, after I drank the drink he brought, I suddenly wanted to sleep and then fell asleep."

"He must have added sleeping pills to the drink," Conan said. "He wants to kill you and lay out the ground as an accident, and when you are drowned here, he will have a proof of his absence."

"Prove that absenteeism?" asked Matsuki Nin.

Conan said: "He is now with Sister Lan."

"So that's it," asked Makoto Ninja, "but why did he kill me?"

"We have to ask him to know this question," Conan said. "Let's leave here quickly and call the police."

"Not good," Ayumi shouted, "the water is in."

"Let's go quickly." Conan said anxiously.

The four members of the detective group and the Moonyu Nin hurriedly got on the rubber boat. Yuanta tried hard to drive the boat out of the hole, but as soon as he got outside the hole, he was washed back by the tide. The rubber boat hit the stone wall and broke suddenly. The four members of the detective group and the Moonyu Nin hurriedly jumped off the rubber boat.

Ayumi asked, "Conan, how do we go back?"

Mitsuhiko said: "Now that the waves are so big, it's impossible to swim out."

"It's amazing," Yuan Tai shouted with his head in his arms, "Who will save me? I don't want to die yet."

Conan said: "Everyone calm down and don't panic."

Azumi shouted, "How could it be as easy as you said?"

Mitsuhiko said in a crying voice: "If you wait for a while, the tide will be filled with sea water."

Yuan Tai shouted: "Then everyone will drown."

Conan was also very anxious, but there was no way for a while. He accidentally discovered that several fireflies were flying in the sky.

Yuan Tai also discovered it, "How come the fireflies are here?"

Wangyue Nin asked, "It's really strange, how could the fireflies be in a cave that is flooded with tides?"

Reminding the Maori fish, Conan said: "By the way, there must be another exit in this cave. Now we can only find that exit and go out from there."

Mitsuhiko asked, "But what if that exit cannot be passed by?"

"No," Conan said, "Although the stone carving fish that my uncle caught was very large, there were no scars on the fish, so the exit was definitely not small. When the tide was full, the sea water poured into the cave and then flowed to the other side. On the other side, I guess it was a pond or something, so I could catch deep-sea fish."

"Yu?" Yuan Tai compared his body, "Is it really OK?"

"It must be possible. Didn't uncle catch a lot of fish? If the hole entrance is small, I can't pass so many fish at once." Conan said.

"I believe Conan won't say it wrong," Ayumi said.

Yuantai said, "Okay, let's go."

The five people followed the fireflies for a short time and found that the fireflies were flying out of the top of the cave. They were stunned for a moment. Then Conan had to use the method of throwing stones to ask for directions, and listened to the echo to distinguish the truth and reality. Not long afterwards, the five people met a group of seabirds, so they followed, but were thrown away by the seabirds soon after.

While sighing at the hugeness and complexity of the cave, Conan had to continue to throw stones and ask for directions. However, perhaps the sea water had already poured into the cave, and the voice could no longer be distinguished.

When the five were in a dilemma, a large swath of sea water poured in and swept them away. As a result, they were lucky and washed directly by the sea water to the exit. The exit was not small, and it seemed that they could get them out. However, it seemed that Yuan Tai was the first to be washed to the exit and then stuck in the exit, causing the others who were holding their breath and waiting to go out to be anxious.

After Conan swam over, he found that it was Yuanta's body jacket problem, so he cut Yuanta's body jacket with a folding knife that had cut the drift bottle and let it go.

Now, Yuan Tai was washed out by the sea and hit Maori who was waiting for the fish to come out at the exit.

"Oh! No! Help." Maori screamed and was knocked into the pool...

Time goes by a little.

Ran and Yuanko met Haruhiko who came back to return the boat while talking about Maori fishing at the fishing holiday house.

"I probably know this, I know why Mr. Maori can catch so many fish," Haruhiko smiled, "If I don't mind, I'll take you to see it."

"Okay, where is it? Take us there quickly." Yuanzi said.

"Then I'll trouble you." Lan said.

Afterwards, Kasuhiko Kasuhiko took Ran and Yuanzi to find Maori. Next to a mountainside pond with the "No entry" sign, Maori didn't fish at all, but was drinking beer and looking at a cave.

"Dad, what are you doing?" Lan asked.

Maori shuddered, looked back and asked, "Why are you here?"

Haruhiko said, "I am Haruhiko. I'm very happy to see you, Detective Maori."

"Hello." Maori said.

"Of course I'm seeing you how you fish, uncle." Yuanzi smiled, "The result..."

"This, this..." Maori was speechless.

"It's better for me," said Haruhihiko, "this wall cave leads to a cave by the sea. When the tide is high, the sea water will pour into the cave and come out from here."

"In other words, the fish will also come over," Yuanzi smiled, "so that's how those fish came."

When Maori was embarrassed, the phone rang, "I'll answer the phone."

The call came to Yamazaki, "Uncle, do you know where Ran and Yuanzi are?"

Maori thought about it and said the address.

Not long after, Yamazaki and Midako came over, and the four of Maori were shocked when they saw the big fish holding that Midako was about two meters long, with a maximum diameter of about one meter, and a triangular fin.

Meidaizi stretched the fish mouth to Yuanzi and Lan, "How is it? You're still alive."

Seeing the hideous teeth in front of him open, revealing a big mouth that seemed to be able to bite off his head in one bite, Yuanzi and Lan screamed and avoided.

"Is this the fish you caught?" Maori asked in surprise.

"Uh," asked Medeko, "Brother, is this a fishing event?"

Yamazaki smiled and said, "For sure, the ones you caught when you caught when you caught the sea are of course the ones you caught."
