On Saturday, July 20, Onoguchi Station, Shibukawa City, Gunma Prefecture.

This is the nearest railway station to Gomura Hashima, Yoshima County. You can reach Boshima in about 30 minutes walk. Conan and others got off the bus and asked the staff at the station and learned that there was a lemon-scented child in the afternoon. He asked how to get to Boshima...

On the way to Box Island.

After wiping his sweat, Yuanta couldn't help complaining: "What the hell is this guy Mitsuhiko doing? Why did he come here?"

Azumi said, "That's to say, let's find it easier."

Haibara said: "It's very strange. The classmate Engaya who has always been cautious and will not act without permission will actually run into the mountains alone without us."

Dr. Agasa smiled and said, "Maybe he is for some special reason."

Yuan Tai asked: "A special reason?"

Dr. Agasa fantasized: "It's like he met a girl on the road, and fell in love with her at first sight, and came to this place in a daze."

Ayumi blinked, "Love at first sight?"

Dr. Agasa asked back: "Don't people often say that the taste of first love is sour, sweet and bitter? Isn't it the same as the lemon smell on Mitsuhiko's body?"

Conan said angrily: "You can really tell me, Mitsuhiko's actions are obviously premeditated."

Haibara asked, "Oh, so you know?"

"That's right." Conan smiled, "When it comes to this matter, Dr. Agasa is blamed.

"Me?" Dr. Agasa didn't understand, "What does this have to do with me?"

"Because of some of your words," Conan laughed, "Miyohiko decided to act alone and give everyone a surprise."

Haibara said angrily: "Can you make it clear?"

"If you make it clear, there will be no surprises." Conan smiled, "I can give you three tips, one is the famous Box Island product, the second is the bamboo leaf rice ball, and the third is sunscreen."

"What are these?" Yuan Tai was confused...

Not long after, Conan and the other two walked to the Borashima area. Conan turned on the tracking function on his glasses and found Mitsuhiko's detective badge signal, but the signal was not very good, and he did not answer the call.

Dr. Agasa said: "Maybe it's because of the influence of trees and the signal is not good."

Conan said, "Then let's go."

Azumi said: "The sun is going to set, we must find Mitsuhiko quickly."...

Conan and the other two walked along the road and soon entered the mountains. Then they found some vehicles at the end of the road, one of which was a police car and the rest, which were vehicles used by the police guards.

Yuan Tai asked, "Is this an incident?"

Conan said: "It should be the police leading the police to search for someone or something. Judging from the police force used, it is not a serious incident."

Dr. Agasa asked, "Do you want them to help?"

Haibara said: "Let's talk about it when you meet it."...

More than ten minutes later, Conan and others met the search team member and were handed over to the leader, who turned out to be the Yamamura police officer.

The Yamamura police officer asked happily: "Why are you? Is Detective Maori here too?"

"Uncle Maori is not here," Conan asked, "Police Officer, what are you doing here?"

Yuan Tai asked, "Is there something happened?"

The Yamamura police officer said, "Oh, we received a call from the police. Someone in Hamamna Mountain is fighting with a knife."

Azumi asked, “Just like ancient people?”

The Yamamura police officer smiled and said, "Yes, our police found a half-cut knife in Hamame Mountain. After investigation, the broken sword was cut off by another knife. Our police found the sword-selling workshop based on the imprints on the broken knife, and confirmed that someone bought two knives of the same craft a week ago."

Yuan Tai said with interest: "Wow, there's really someone fighting."

Conan asked, “Is it confirmed a duel?”

The Yamamura police officer asked, "Of course, if it weren't for the duel, how could a person buy two knives?"

Haibara said: "Maybe it was a murder trap set on purpose."

The Yamamura police officer said, "That's why we came here."

"But, officer, why are you here?" asked Dr. Agasa, "It doesn't seem like this is Haruna Mountain?"

"This is indeed not Hatsune Mountain, but it is connected to Hatsune Mountain." said the Yamamura police officer. "Our police found some blood at the scene of the Broken Knife. Because it rained last night, it believed that there were much more blood. It was suspected that one of the duels was seriously injured, but the surrounding hospitals did not receive such a patient. So we think the injured are still in the mountains. Unfortunately, the smell of blood was washed away by the mountain rain. Otherwise, the police dog could be used. Now we can only search for a large range of things."

Haibara said: "Maybe it has been buried and can't be found."

"Uh..." The Yamamura police officer couldn't answer, so he changed the topic, "What are you here to do again?"

Dr. Agasa said: "We are here to find Mitsuhiko. You have seen this child before, so now I'll ask the police officer to help me find it."

"He's right..." Before Conan finished speaking, he found that the tracking map on his glasses was gone, and he was stunned.

Haibara asked, "What's wrong?"

"It's out of power." Conan smiled bitterly, "I haven't used it for a long time, and I forgot to charge it when I came."

"What's out of power?" asked the Yama Village police officer.

"It is the tracking glasses I invented," said Dr. Agasa proudly, "it can track the signals of these detective badges." He said and pointed it to the Yamamura police officer.

"You invented it?" Yamamura police officer took Conan's detective badge and looked at it. "I remember when I was a child, I sold something similar. I also bought a detective Qibao."

Ayumi said, "What Dr. Agasa gives us is different from those things." Then she contacted Conan's detective badge with her detective badge.

"You can still talk to the phone." The Yamamura police officer said in surprise.

"And this." Yuan Tai turned on the watch-shaped flashlight on his wrist.

"I invented this too," said Dr. Agasa proudly.

"Is that true?" Yamamura police officer turned on the bright flashlight he carried on and compared it. "It was completely for children to play with."

"Uh..." Dr. Agasa was speechless.

The Yamamura police officer asked, "Hey, since this badge can be used to talk to you, have you contacted him?"

Yuanta said, "Yes, but I don't know why he didn't reply."

The Yama Village police officer touched his chin and said, "Ah, could it be that he had encountered something and was killed and silenced."

"Ah?" Azumi was startled.

Dr. Agasa shouted dissatisfiedly: "Hey, don't scare the children."

"I'm just talking about a possibility." The Yamamura police officer said angrily, "Who asked you to bring him here."

Dr. Agasa shouted, "It's not me who brought him."

Haibara said to Yamamura police officer: "The problem now is that a child has entered your search area. If something happens..."

"Uh..." The Yamamura police officer said nothing.

"Okay, hurry up and find someone." Conan said, "The mountains and forests are no longer visible now."

Dr. Agasa said: "That's right, you have to find Mitsuhiko quickly."

Haibara said to Conan: "You can tell me now, why is Mitsuhiko here?"

"Yes," said Yuanta, "Conan, please tell me quickly."

Conan said: "Mirakami came here because Dr. Agasa said, "Suma's poem about the scenery in summer."

"Summer scenery poem?" Yuan Tai asked, "What's here?"

"Ah, I get it." The Yamamura police officer smiled, "It must be a firefly."

Dr. Agasa said: "I remember that the water quality here in Box Island is very good, and the growth of fireflies requires clean water."

Yuan Tai asked, "Then is the bamboo leaf rice ball used to wrap fireflies?"

Conan said: "That's right."

Azumi asked, "Where is the sunscreen? Can it be used in this forest?"

"I understand," Haibara said, "the sunscreen is mixed with insect-proof ingredients."

Conan laughed and said, "That's right."

Dr. Agasa asked, “So you can find Mitsuhiko where fireflies are infested?”

Conan said: "I can't be sure of this, but I can look along the waterside."

Haibara said to Yamamura police officer: "Hey, why don't you notify the search team using the radio to find the child first."

"Oh, oh." The Yamamura police officer did as he did.

Yuanta said: "Let's start too, we must find Mitsuhiko."

"That's right." Ayumi responded...

On the other side, in the mountains.

Mitsuhiko looked around the dark area and had no idea where to go. However, although she was a little scared, the detective badge on her chest kept making calls, indicating that Conan and the others had found this place. Conan had tracking glasses and could definitely find them.

Ayumi and Haibara must have come too. At that time, they will be very happy to give them the things in their hands.
