One summer day, the detective group went out and took Qianjun's car to surf the beach. In fact, if Kogoro wanted to fish, he took Xiaolan with him. After arriving at the beach, Xiaolan took five children with her hoverboat and shouted excitedly and rushed into the sea. Qianjun went to the sea to dive alone, and Maori stayed on the shore to fish. Qianjun could see clearly under the water, and Xiaolan and others rowed hard, sailing far away against the waves. The main force of the boating was naturally Xiaolan and Yuanta, and everyone was wearing life jackets.

While the children were having fun with Xiaolan, a speedboat suddenly drove across the opposite side and quickly hit the hovercraft. Everyone screamed. The person who drove the speedboat was an arrogant man with dark skin with sunglasses. Beside him was a beautiful woman wearing a lilac swimsuit, and squatted down and screamed. So the hovercraft capsized like this, and Xiaolan and the detective group fell into the water together. The man drove the speedboat back, looked at the people floating up from underwater, took off their sunglasses, and laughed, "Sorry, sorry, are you okay? I was watching the side just now and didn't pay attention to you."

So, everyone boarded the man's speedboat, tied the hovercraft to the speedboat, and drove away from here at high speed. The children got on the speedboat for the first time and screamed excitedly. Arimi said, "It feels so comfortable!" Yuanta also shouted, "This summer vacation is great!" Mitsuhiko said, "It's really worth it for us to take a vacation at the beach this time!" Funo also said, "Fortunately we forced our brother to get on the car, hehe..." Everyone laughed, Conan was funny, these guys.

The surfing man is named Hirohiko Haruhiko, the eldest young master of Hirohiko Haruhiko. Hirohiko Haruhiko is still a bit famous in the upper class, and of course it is impossible to compare with the Suzuki family. The blue sea water, light shines, extending infinitely into the distance. Xiaolan said, "Did we cause trouble for you? It's so embarrassing to sit on you." Huiyan said that it's interesting to have more people. The beauty in the swimsuit is Hirohiko's girlfriend, named Koinin. Xiaolan praised, "You are so enviable! It's great to dive here with the person you like."

Huiyan said that the two had a very different status, so no one could decide what the result would be in the future. Xiaonin's face looked ugly, "I really..." Huiyan sneered, "Just tell the truth, Xiaonin!" Conan was a little strange, "What the hell is this man talking to his girlfriend." Xiaonin was a little sad. Conan suddenly asked Xiaolan, "Where did Uncle Maori go fishing?" Xiaolan shook her head and said she didn't know.

Suddenly, a figure jumped out of the water and squatted gently at the tail of the speedboat. Everyone was shocked. It turned out that Qianjun found that everyone got on the speedboat, so he jumped up when the speedboat was driving. Qianjun laughed, "Uncle Maori said he wanted to go to the largest pond nearby to fish." Xiaolan also remembered, "Early this morning, my father looked for various tools everywhere." Everyone looked up and found that there were many people fishing by the sea, obviously there were no Kogoro, "It should have gone to the pond by the sea."

Huohiko Haruhiko asked who this weird person was. Qianjun didn't know Huiyan, but President Haruhi had seen him. After introducing each other, Huiyan realized Qianjun's identity and his dissatisfaction with him rashly boarding the boat turned into nothing. Xiaoren shouted, "So you are the young master of the Yokono Group." When he heard this, Qianjun got goose bumps all over his body, "Miss Xiaoren, please don't call me that? You can just call me Qianshui." Xiaoren felt that Qianjun had no airs and was very refreshing, so he took the initiative to chat. When a beautiful woman took the initiative to talk, Qianjun was naturally very excited. A cold light flashed across Kurahiko Haruhiko's eyes.

In the Ikeku, Kogoro fished alone, "Here, here, it's a great harvest!" As he spoke, Maori caught another big fish, which was already the sixth. Kogoro didn't notice at all. There was a sign hanging on the fence outside, which said "No entry". On the other hand, everyone returned to the shore and went to change their swimsuits. Qianjun said he wanted to take everyone to swim. After Xiaolan changed into a black X-sensory swimsuit, he ran to find Xiaonin. Xiaonin was not there, but Huiyan said that Xiaonin had a quarrel and didn't know when she left, "She often looked like this, don't take it to heart." Conan said in his mind, "It's obvious that the person who made her tantrum was you, and this person is really strange."

Qianjun shook his head secretly, "I don't know how to cherish such a beautiful girlfriend." Everyone returned to the rest place, Maori came back excitedly from outside, "Great harvest, great harvest!" Everyone watched Maori's box together, the children praised it for their greatness, and Xiaolan also said that his father's fishing level has improved greatly. Qianjun was puzzled, "Uncle, where is this fishing place?" Ayumi also said, "I want to fish too." Kogoro said, "This is not possible." Fumi asked, "Why?" Maori smiled, "Because that was a place that a fisherman secretly told me, this is the secret between us."

Kogoro moved the fish box away, Yuanta didn't like it, "It's not fun at all." Then Yuanta suggested playing beach volleyball, and Mitsuhiko agreed. Ayumi and Fumio called Conan to go there together. Conan was watching the fish caught by the uncle, which contained stone snappers inside. Kogoro glared at him, "So what?" Conan laughed, "It's nothing." Qianjun asked in a low voice, Conan said, "Since it's not the seaside, how could he catch sea fish? I think it was probably fished in a fishing ground." Qianjun shook his head, "Of course not, I guess he caught it in a pond where the seawater invaded nearby. Think about it, the uncle is so stingy, how could he be willing to spend money to go to the fishing ground?" Conan was stunned, "That's right, he would rather use the money to buy wine..."

As he said this, Kogoro opened a can of beer and laughed, "I, Kogoro Mori, this talent is not just about being a famous detective." Conan laughed, "I'm full of stubbornness!" Haruhiko Hirohiko was shocked, "Mori Kogoro?" Maori wondered who this dark-skinned man with brown hair was. Qianjun smiled and introduced him to both parties. Kugoro Haruhiko was a little panicked and his eyes flashed. Then Conan was forced to go to the beach to play volleyball by Fumino. Qianjun asked Xiaolan to dive together. Xiaolan was really beautiful today and traveled with the beauty. Qianjun thought it was also a kind of enjoyment.

On the beach, Yuanta tried too hard and hit the ball out of bounds again, so he had to run over to pick it up. Yuanta found a drifting bottle on the beach, and there was a piece of paper in the bottle, so he brought it back. Conan found a knife to cut the bottle open, and Mitsuhiko said, "Is it a treasure map?" Yuanta looked forward to it, "Is it a treasure map?" Arimi smiled, "This is like the plot of a movie and a novel." Conan took out the note, opened it and called Fumio, "It's SOS, this is a letter of help." Conan also found the following signature, "Xiao Nin".

The detective team was shocked, Arimi was a little scared, "How could Sister Xiaonin ask for help?" Yuanta said, "It was still drifting over by the sea!" Haruhiko heard everyone's voices, walked over from the side, and smiled, "I thought she had gone back. It turned out that this woman was still here." Conan asked him why he said that, Haruhi said that Xiaonin often played such pranks, "It was to make me worry, this woman was really troublesome." Kogoro lay not far away and half drunk and half awake, "Trouble? It was about to be full of tide. I think I'll go again."

Xiaolan and Qianjun came back from swimming, changed their clothes and walked over. Qianjun received a call from Jingyang and were busy accepting inquiries. Xiaolan shouted to the detective group, "The seaside is too dangerous, you can't go to the beach." The children agreed. Turned back, but began to discuss privately. Azumidao, "If it's really a sister Xiaonin asks for help, it's bad." Yuanta suggested, "Since that's the case, let's go and take a look." Mitsuhiko frowned, "But where to investigate? If she is on an uninhabited island, then..." Conan shook his head, "No, it's impossible in time. This piece of paper has not been dried by the sun." Wen Nai said, "That means, Sister Xiaonin must be not far from here."

Conan then suggested that Qianjun help find it, but the detective team directly rejected the proposal and planned to rely on their own strength to solve it. Conan had no choice but to remind Xiaolan not to let Haruhiko leave his sight. Xiaolan was puzzled, "Why is this?" The children bowed together, "Please ask for this matter!" Then they ran away together, Xiaolan shouted, "Wait a minute, where are you going?" Kogoro suddenly became energetic, "I'll go challenge it again." Haruhiko came over, "I'll go with you, Mr. Maori, I've known it for a long time, that pond is right? I can't play with this nearby area anymore." As he spoke, Huiyan pulled Kogoro and left.

Xiaolan stamped her feet, "Dad, we should be ready to go back... I'm so angry. Why are you all so willful!" Qianjun was busy explaining what happened to the beach today. Jingyang and the others were naturally unhappy, thinking that he must be taking the opportunity to peek at the beauty again. An old man wearing a straw hat came to the distance, packing up the beach garbage, complaining, "Young people recently..." Conan waved hello. The old man was very angry when he saw the detective team, and stepped forward to take Conan's bottle, "What are you doing in a sea bath? You have dived again, which has dirty our sea!"

Conan and others had to interrupt the chattering old man and asked him where the bottle floated over? The old man still told the general direction of the detective team. The children set off, Yuanta was carrying an air cushion alone, with shell picking tools hanging on his waist. Mitsuhiko asked, "Yuanta, why are you bringing that? We are not going to the beach to play while the tide is low!" Yuanta was angry, "I want you to care, I am the leader. I finally came to the beach without bringing some clams, clams, and Jiukong, how can I go back?" Azumi laughed at Yuanta for knowing how to eat, and Funno helped him out, "If you catch it, eat it!" Conan really regretted it, "I think all you think of is just playing!"

Everyone walked forward, and Arimi almost fell into the rocky stream. Fortunately, Yuanta and Mitsuhiko caught her. Mitsuhiko reminded her that the tide was about to rise, so be careful. At this time, the children found Xiaonin in the rock cave in front of them, and she was lying motionless. Conan hurriedly urged everyone to inflate the hovercraft as soon as possible, and the tide was about to rise. Then everyone sat up and rowed inside. When they came to the front, everyone woke up Xiaonin. Seeing that Xiaonin was fine and still alive, everyone breathed a sigh of relief. Conan hurriedly asked what was going on.

It turned out that Huohiko Haruhiko deliberately tricked Xiaonin to play diving games. Huihiko said that when the tide was full, a cave would disappear into the sea. They came here. Xiaonin drank the drinks handed over by Huihiko, and suddenly wanted to sleep. He climbed on the ground and couldn't move. Huohiko Haruhiko took the diving equipment and drove the speedboat and left. Xiaonin took advantage of the last moment of awakening and sent a distress signal with the drink bottle. Conan judged that sleeping pills were added to the drink. Haruhiko Haruhiko wanted to create an accident and let Xiaonin die. When Xiaonin drowning, he must have absenteeism. He deliberately knocked over everyone's hovercraft and quarreled with Xiaonin. All of this was his plan.

Xiaoren was sad, "Why?" Conan laughed, "This is the police's job, let's leave quickly and call the police!" Wennai found that the tide had risen, so everyone hurriedly got on the boat and rowed out, but a big wave came over, pushed the boat back into the stone, and the hovercraft was scrapped. Everyone had to get off the boat in a hurry, and the detective team was really scared. Conan complained secretly, "Now the waves are so big, it's impossible to swim over. And there is a Xiaoren who is not very conscious around him."

Arimi was anxious, "What should I do?" Funo also cried a little, "Who will save us?" Yuan Tai shouted, "I don't want to die yet." Conan asked everyone to calm down and not panic at first. Then he immediately took out the detective badge from his life jacket pocket and shouted for help from Qianjun. Qianjun hung up the phone and found that the person was gone, so he enjoyed the high tide view alone from the high shore. Conan's call for help came from the watch. Qianjun was shocked after hearing this, "Are you mistaken? Why don't you call me? I like heroes to save beauty the most!" Conan was so angry, "Is it that stupid, when are you still thinking about beauty, come and save people quickly!"

Qianjun also knew that the situation was serious, "I'll go there right away. However, the situation is not good, you go to the high ground first..." Conan ended the call and told everyone not to worry. Qianjun would come over immediately. Arimi cried angrily, "It's easy to say!" Mitsuhiko also said, "If the sea water fills the place..." Yuan Tai shouted, "We will definitely be drowned." Funo also said, "When the monster brother comes over, we can only collect the body for us." Conan knew that everyone was right, Qianjun would not appear immediately, and even if he comes over, how can everyone leave?

Arimi discovered fireflies flying deep into the cave. Conan was also surprised that fireflies were very picky about the direction of water flow. This cave, which would be filled twice a day by sea water. "How could it be? Could it be..." There is only one reason. There is an exit in the cave, where the fireflies came in. Conan thought that now, he could only escape inside. Arimi hurriedly reminded him that if people could not pass the exit inside, everyone would be in a jar. Yuanta looked at his body, "Conan, we are not fireflies!"

Conan explained that Qianjun once said that Kogoro's fish were caught from the pond cave, and the stone snapper caught by Uncle Maori was much larger than the freshwater fish, and his body was not scarred. It can be seen that the outlet was not that small. Those fish swam into the cave from the direction of the sea before dawn. After the water was full, the fish passed. Uncle caught stone snapper at another outlet. The pond cave must be very large, so you can catch sea fish without the sea. Qianjun also told Conan something that usually, a person's head can squeeze through the gaps and the body can also squeeze through, as long as the gaps are not completely tortuous.

The detective team praised Conan for having a good time. If he stayed here, he would definitely be drowned. Everyone believed that Conan was right, so they decided to give it a try. Walking in the cave, Azumi screamed, and everyone asked hurriedly, it turned out that it was just the water dripping on Azumi. Everyone breathed a sigh of relief, Mitsuhiko said, "What did I think it was?" Yuanta also said, "Don't scare people, okay?" Azumi was a little shy, "I'm sorry!" Everyone continued to move forward and soon got lost.

Yuan was too anxious and rushed forward, but hit the stone wall. Conan suggested that everyone follow the fireflies and lead to the entrance as long as there are fireflies. The detective group looked for fireflies separately. Xiaonin gradually recovered and everyone went out together. Yuanta, Mitsuhiko, Fumi, and Xiaonin reported that they did not find it. Fortunately, Arimi successfully found the fireflies, and Conan ordered to set off. Before leaving, Conan notified Qianjun with the badge, and Qianjun complained, "It's really, I've already arrived outside the cave and prepared a speedboat." Conan smiled bitterly, "It's too late to look back now. Go to the pond where the uncle fishes to pick us up!" Qianjun had no choice but to dive away, board the speedboat and sail to the shore.

The detective team continued to move forward, and reached a fork in the road, facing the choice of two choices. This time there were no fireflies, and the detective team was in trouble. This time, Conan used the method of throwing stones to ask for directions, using the echo to determine whether there was a path. If the echo was loud, it would be a dead end. Gradually, it would mean that there was a path ahead. The water flow gradually entered, and the detective team was struggling to move forward. In a wide place, he heard the sound of birds flying. Conan believed that the birds came in to find food and were now flying towards the entrance.

Conan led everyone to run quickly, and the situation was very urgent. Asuka left, but the detective team failed to catch up. Everyone was a little depressed. Kogoro and Haruhiko were frightened by the group of birds that suddenly flew out in the cave. When the uncle saw Haruhi was looking at the watch, Haruhi said that it was about to be full of tide. On the shore, Xiaolan packed her luggage in anger and complained about these willful guys. Suddenly, she remembered Conan's advice and asked herself to watch Haruhiko, "It's not good, I forgot!" The old man came over and told Xiaolan to take away everything. Xiaolan hurriedly asked him where the largest cave was?

At this time, the detective group in the cave was dead, and Conan was helpless, and the detective group screamed in shock. At this time, the tide was surging. The whistling sea water rushed everyone deep into the depths. In an instant, the children's screams and shouts were heard, and Koin was washed away by the torrent. Soon, everyone's flashlight also fell off, and it was pitch black all around. Arimi and Fumio screamed in screams. Unconsciously, everyone was washed up by the water flowing above the arch of the cave, and the sea water began to flow towards another exit. However, everyone could not tell the difference between the upper and lower and left. Conan saw the light, and the exit was right in front of him.

Kogoro and Haruhi also saw the surging and erupting sea water. Many sea fish fell on the shore. Kogoro shouted happily. However, the water suddenly stopped. Kogoro was surprised, but Haruhi Hirohiko quietly pulled out the pistol behind him. It turned out that Mrs. Yuan was fat and her life jacket blocked the narrow part of the cave. The detective team was facing a desperate situation again. In desperation, Conan took off the shell-picking tool on Yuanta's body and cut the life jacket. Yuanta was washed out by the huge water pressure, and everyone came out of the water. Kogoro crawled near the entrance of the cave and listened to the strange sound inside. Yuanta soon had an intimate contact with Maori, and the two of them screamed and fell into the cave together.

Then, following the high-speed water flow, Conan, Funno, Mitsuhiko, and Arimi rushed out one after another, and finally Xiaonin in a swimsuit. Everyone floated up from the water, gasped, and almost suffocated to death just now, and finally saved. Seeing Xiaonin also float up, Haruhi's face changed drastically. Kogoro also came up, "What's wrong with you? Why did you come here? Where did you rush over?" The children crawled up, and the facts proved that Conan's reasoning was correct.

At this time, Haruhiko Kidna kidnapped Azumi with a pistol, "I had long thought that this might happen, and I was really impressed." The children screamed, and Kogoro was furious, "What do you want to do?" Haruhi raised his pistol, and Conan hurriedly said, "If you fire, the careful planning accident will be in vain!" Haruhi sneered, "Little kid, do you think I dare not shoot? I have enough bullets to deal with you. I am a legal person holding guns." Haruhi pressed the gun on Azumi's head, and Azumi screamed in horror. Kogoro and Konori both asked him to stop, and Konori was angry, "The person you really want to kill is me, it has nothing to do with that child."

Haruhi was angry, "It's all your fault for this matter. It's okay if you disappear from the world." Xiaonin asked why he wanted to kill himself? It turned out that Haruhiko's father introduced a rich daughter to a rich family and had been engaged successfully. "I don't want to leave home. I'll be poor with you for the rest of my life. I would rather be my eldest young master for the rest of my life." Xiaonin was angry, "You're too much!" Conan was also angry, why didn't Qianjun arrive yet? If this continues, everyone will be dead. Haruhi snorted, "You all know the truth, there is no need to use you anymore. I'll let you go to the sea to feed the fish!"

As soon as he finished speaking, the uncle and Xiaolan arrived. The old man angrily threw out a garbage bottle and smashed it at Kasuhi. Kasumi could dodge. Qianjun, who was hidden behind the big stone, jumped out. The Qixi Sword flashed, and Kasumi's pistol turned into two pieces. Azumi was also taken away by Qianjun. Then Xiaolan rushed over and attacked and kicked, "I will never forgive the enemy of women!" Kasumi fell gorgeously in the pond hole, and the detective team rushed up and captured Kasumi who was unconscious. "Young detective team, great success!" It turned out that Conan and the others had arrived shortly after they fell into the water, but Kasumi grabbed Azumi in advance. Qianjun was afraid of the mouse and did not dare to act rashly. However, he was prepared for the worst and aimed the gun in his hand at Kasumi's head. If Koran and the others came one step later, their lives would be Kasumi, and not Yoshida Azumi.

Sato and Takagi had already received Qianjun's call and rushed to the scene. It happened to be the finishing work, which made Sato very depressed. Takagi was very happy. After coaxing Kasugaki Hirohiko, he stuffed it into a police car and easily got a piece of credit. Sato ordered Takagi to record the children, and she was responsible for the recording of Koin, Koran, Qianjun and Kogoro Mori, and cleaned the recording of the uncle. Takagi agreed with a wry smile that he had to face the exaggerated language of the detective team again. By the time the transcript was finished, it was already dark. Sato and Takagi left the police car, and Koinin's eyes were all lonely.

Maori was very miserable, and was caught by the cleaned man and criticized him. The uncle confiscated the fishing gear of the Maori detective and taught Kogoro a lesson for an hour, because the lake would rise when the tide was full, and fishing in the pond was very dangerous. Conan was funny, "Who asked him to go to the pond to fish!" Qianjun also said, "It's worth being scolded!" Xiaolan and the detective team laughed at the ugly appearance of crawling on the ground and begging for mercy. Xiaonin, who was originally sad, also smiled.

At the end, Haruhiko Hirohiko attempted to murder his girlfriend Konomi, kidnapped Akimi, intending to kill everyone in the detective group. Kogoro Mouri was sentenced to 15 years in prison by the court. The Junior Detective Group cracked the murder of the High Tide Cave, and the Metropolitan Police Department gave him a C-level reward. After all, no one died. Conan asked Qianjun, "Why didn't you shoot? This is not like you..." Qianjun sighed, "It's not someone who said that you should not easily deprive anyone of your life. Besides, if the Memu police department finds that I shot the prisoner again, I will definitely confiscate my gun certificate and all the gun bullets. Speaking of which, if that old man is a little late, you should know the tragic ending of Haruhiko." Conan smiled and remembered Okita who was shot dead by Qianjun. Haruhiko Hirohiko was really lucky.
