Just an hour after Kuroba Kuito sneaked into the house, Ye Genyi thought and researched from the outside and took care of guarding an hour.

Dr. A Li also drove the beetle car, carrying the five-member team of young detectives to camp in this desolate forest.

Six people work together.

The three little people went to pick up firewood for the fire, Conan and the doctor set up a tent, and Ai Huihara was in charge of chopping vegetables.

The tent was soon set up.

Conan sat on the floor mat with his mobile phone in his arms and kept pressing the melody of "Seven Children", his face full of depression.

It can be said that this is the only clue that he can claim to have gained from the incident in the Domoto Concert Hall.

What about other than that?

The case was solved, the bomb was dismantled, Fu and Jiang committed suicide, and I... and Qiu Ting Lianzi floated on the boat for an afternoon. If there happened to be a telephone near the reservoir, the two would float from there for a while longer. You might catch a cold the next day.

depressed……

so depressing...

Conan felt like he was going crazy.

"Xinichi, what's the matter with you?" Dr. A Li noticed his abnormality: "Is it because you are not feeling well?"

"No," Conan sighed silently, "It's the thing I asked you before I left, how is it, it should be... I think too much?"

"that matter?"

Dr. A Li was stunned for a moment, and suddenly said with a slap on the forehead: "Oh! You said the melody of 'Seven Children', right? I have heard it, of course I have heard it."

"what?!"

Conan's body tensed up sharply, his pupils contracted sharply, and he said sharply, "Really! Is it Gengyi or Huiyuan!"

"Ah?" Dr. Li was at a loss. "What does this have to do with Geng Yi and Xiao Ai?"

"Eh???"

Conan was stunned, "Doctor, are we talking about the same thing?"

"Shinichi, what happened to you?"

Dr. Li was even more strange, "Didn't you ask me if I have heard the melody of the song 'Seven Children'..."

As he spoke, he sang with his throat, which was only slightly stronger than a certain tone-deaf detective, and finally said:

"That's right? I used to sing it on the way home from school... What's the matter? Is it a holiday homework assigned by the music teacher?"

"I'm not asking you before, I'm asking you... Forget it," Conan Banyueyan handed over the phone and confessed directly, "Remember the 0858 I mentioned to you after I came back from Okinawa last time? Use your phone Does the sound of these numbers sound like the melody of that song?"

Dr. A Li took the phone, tried to press it again, and said with a soft "Huh":

"Huh? It's really similar..."

"Yeah, I asked Miss Qiu Ting, who has an absolute sense of voice, for advice, which finally made me sure of one thing."

Conan's face was serious, "The last time I saw the picture after I was kidnapped by Belmod, the expression on her face when she sent an email was not lonely and nostalgic... It was because the sound of the button on the phone gave me this illusion."

"Then... shouldn't it, their eldest's email address is 'Seven Kids'?"

Hearing this, Dr. Li finally couldn't control his emotions, and he was shocked and a little suspicious: "He, hehe... Xinyi, could it be that you are thinking too much? How could such a criminal organization put children's songs on it? The melody is set to the email address..."

"Maybe they use the melody to memorize the email address. This way, no traces are left on the phone. Even if it is accidentally lost or stolen, the number will not be discovered..."

Conan analyzed, "And using well-known tunes, in addition to being convenient for memory, will not cause others' suspicion."

"Wait a minute, Xinyi! Then you just asked me what Gengyi and Xiaoai mean?"

Dr. Li stared blankly, "You shouldn't be..."

"Oh no!"

Conan shamelessly said:

"Don't mention that guy Huiyuan for the time being. Didn't that woman named Belmod once contacted you under the pseudonym 'Wei Meisi' and had a brother! Although he is a little bit better than me, But for things that I'm not interested in, I don't care at all, I'm worried that he's not vigilant enough to fall into the trap of the organization..."

Hai Yuanai, who had long been attracted by the surprise of the two people in the tent, overheard this and couldn't help but nodded...

Sure enough, compared to Gengichi, this guy Kudo really makes people feel very insecure...

"So that's how it is," Dr. A Li breathed a sigh of relief, and pressed the phone a few times, trying to piece together the melody of "Seven Children", but he quickly failed:

"The 'Crow' at the beginning is similar to the button sound of 0858, but Shinichi, how did you press the 'Why Sing' at the back? Why can't I press it?"

"That's because ordinary people can only feel strange in most cases, but they can't clearly distinguish the subtle rises and falls on the scale. Give me your phone..."

Conan took the phone and gave a more detailed explanation:

"For example, 1, 2, and 3 of the phone key sound are close to 'Fa', 4, 5, and 6 are close to 'So', 7, 8, and 9 are close to 'Ra', and ※, 0, and # are close to 'Si'. , the ratio of the number scale in the mobile phone to the music is 3:1. Take the scale of 'Fa' as an example. If you press it in the order of 3, 2, and 1, the pitch will become lower and lower, so the first The number is not 0, it should be #, according to this logic..."

He extracted the sound in his mind and entered the string of numbers on his mobile phone, which he has been repeatedly deleting for the past two days:

"#969#6261... Even if this is not the email address of the bosses behind the black men, it must be a far bigger role than Belmod. I now even doubt the email numbers used by every cadre in their organization. The prefixes are similar to this one!"

"Difficult, do you mean..."

Dr. A Li was shocked, "Shinichi, have you been in contact with them already?"

"How is that possible? It must be my own identity that will be exposed first by doing this," Conan sighed, seeming to be somewhat resentful: "It just so happens that there are no cases that require me to act in the past two days, so I was wondering if I should ask Takagi. The police officer will contact the communication company to find out the owners of this group of numbers, and then proceed to the next step of investigation..."

"It will be fatal~lightnovelpub.net~ Hui Yuanai came out of the shadows, did not hide her eavesdropping behavior, and said:

"Let's not judge whether it is feasible for you to use a set of numbers to investigate the organization. Even if this road can really go through, do you believe that as long as the behavior of Officer Takagi is detected by the organization, he will be in a certain period of time. Suddenly disappearing from the world, and then being locked in a secret room where no light can be seen, subjected to torture and torture you can't even imagine..."

Haibara Ai took a deep breath and swept over Dr. Agasa with a burning gaze, and then landed on a certain Death God primary school student, and continued:

"If he can survive without talking, you may not be implicated in a short period of time, but police officer Takagi's parents and his lover will be poisoned one after another. If he does, it can make people smaller in APTX-4869. Before the effect was revealed, do you think the organization would think it was you, a child, who was investigating, or the famous Maori detective behind you?"

She paused and took a deep breath, not knowing what mood she was in, and said:

"Blindly rushing forward doesn't mean how fearless you are. On the contrary, it will make you smash your head and blood in a fog. Let's figure out the direction first..."
