Conan: I Am Not a Snake Spirit

"After I saw the message in the afternoon, I replied to the other party with a virtual phone number generated by the Internet." Kaito Kuroba rummaged through the communication records on his mobile phone. "About an hour ago, the other party dialed that number. Transferred to me, I communicated with the other party, and the other party also used a virtual number and a voice changer..."

With that said, Kuroba Kaito clicked on a call recording saved in his phone.

"Kaitou Kidd? I'm the one who left you a message before, asking you to steal the sunflowers..."

The voice in the recording was changed by a voice changer and turned into a sharp tone, which reminded Chi Feichi of the 'little yellow voice' in his previous life.

Kuroba Kaito also changed his voice during the call, using a dull male voice, which is easily reminiscent of a burly man. "Then let me get straight to the point. You have already mentioned the content of the commission in your message. and reward, but I still want to know, how much gem-related information can you provide me? You know, it may be more difficult to steal Van Gogh's famous paintings than to steal rare gems. If the benefits and risks are not proportional, I am I won’t take any chances!”

Soon, the other person answered in a minion voice, "I can provide you with information about multiple gems that are on display in the museum, including the famous Eraniel gem..."

After that, the other party reported the reputation of some well-known gems and briefly talked about the characteristics of some security defense systems used by the museum to prove that he had a lot of museum information.

"When do you want me to take action?" Kuroba Kaito asked in a dull male voice.

"Of course, the faster, the better!" the person on the other side immediately replied.

"I will seriously consider it," Kuroba Kaito asked again, "How should I contact you in the future?"

"If you can steal those two paintings, I will naturally contact you again. Then you can use the paintings to exchange information with me. This will be safer for you and me... Kidd, I think this is a It’s a deal worth trying. Once you’ve considered it, you can start taking action at any time. I’m waiting for your good news!”

The other party didn't give Kuroba Kaito another chance to speak, and cut off the communication after speaking.

Seeing the end of the recording, Kuroba Kaito took back his phone and said thoughtfully, "Judging from the voice, the other party should be an adult woman, or a man who usually speaks with a tight throat and likes to imitate women's speech."

"The other party used a voice changer during the call, and the pitch was adjusted very high." Koshimizu Nanatsuki was a little curious, "Can you tell whether the other party is a man or a woman?"

"Of course," Kuroba Kaito showed a confident smile on his face, "Generally speaking, the vocal cords of adult men are longer and thicker, while the vocal cords of adult women are shorter and thinner, just like the thick strings and chords in a piano. The sound produced by thin strings and thick strings is low and deep, while the sound produced by thin strings will be higher and thinner. Therefore, the pitch of most adult male voices is much lower than that of adult women. Most people use it to distinguish male and female voices. The method is to listen to the pitch of the sound and the thickness of the sound. However, it is not just the strings that can affect the sound of the instrument, but also the resonance cavity. The same goes for human vocalizations..."

"When an adult woman speaks, her voice will have obvious resonance in the nasal cavity." Chi Feichi took over and briefly explained the difference between the 'resonance cavity'. "When an adult male speaks, the resonance from the throat to the chest area will be greater than It’s more obvious in women.”

Kuroba Kaito continued to explain with a smile, "When we are disguising, if we want our voice to change between male and female, in addition to compressing the vocal cords and controlling the pitch change of our voice, we must also change the voice at the same time When it comes to the resonance position, when you produce a male voice, the resonance position of the sound is concentrated in the chest cavity, and when you produce a female voice, the resonance position of the sound is concentrated in the nasal cavity, so that the sound produced will be more realistic and natural. "

??????????.??????

"The voice changer can only be used to adjust the pitch, but cannot help people change the resonance cavity when speaking," Chi Feichi said. "In the recording played by Kaito just now, the other party had the characteristic of using nasal resonance when speaking, so Kaito Only then will they think that the other person is an adult female. In addition, if an adult male often makes himself produce a high and thin voice that is close to that of a woman, he may also learn to use nasal resonance, so it cannot be ruled out that the other person is a male who uses female vocalizations. "

"Also, when I communicated with the other party, the other party spoke fluent Japanese the whole time," Kuroba Kaito said, stroking his chin. "During the period, some pronunciation habits of Japanese girls also appeared. I think the other party should be in Living in Japan…”

"But when the other party said the English names of gemstones like 'Elaniel', the pronunciation was very American," Chi Feichi added, "It didn't look like Japanese pronunciation habits, nor did it sound like English, French, German, or Japanese pronunciation. I like the pronunciation habits of these countries, so the other person must have lived in the United States for a period of time.”

Nanatsuki Koshizui thought about it and concluded seriously, "In other words, that person is probably someone close to Mr. Jirokichi, or someone who is currently monitoring and investigating Mr. Jirokichi. He has lived in both the United States and Japan. For a while, it was an adult woman or a man who was good at imitating women’s speech..."

Chi Feichi looked at Terai Huangnosuke and said, "When I meet Mr. Jirokichi tomorrow, I will pay attention to whether there is anyone suspicious around Mr. Jirokichi."

"I'll go investigate too," Kuroba Kaito thought, "We'll split up tomorrow. You go to meet the Suzuki uncle as planned. I'll disguise myself and sneak into his place in advance, so we can take care of each other... "

Terai Huangnosuke thought about this rare joint operation, and he perked up, "What about me? Do you need me to do something?"

"Fei Chi can contact Suzuki Consultant without infiltrating. I may need disguise and support, so grandpa will continue to be my assistant tomorrow!" Kuroba Kaito said cheerfully.

"Then I will be Mr. Chi's temporary assistant tomorrow," Koshimizu Nanatsuki added with a smile, "If we don't find any suspicious characters around Mr. Jirokichi, I can also ask Sonoko about the situation..."

The four people quickly determined their actions for tomorrow.

Chi Feichi told Kuroba Kaito the hotel where Suzuki Jirokichi stayed and everything he learned about it. After that, he and Koshimizu Nanatsuki returned to the bedroom. After washing, they found a 'Maleficent' pill from the medicine box. Take with water.

Koshimizu Nanatsuki climbed onto the bed and reached out to help Chi Feichi pull the quilt away, "Mr. Chi, isn't the sin of jealousy more uncomfortable? In the previous sin of anger experience period, you didn't take so many medicines... "

Chi Feichi lay down on the bed, "It's just because there are a lot of things to do this time and I don't want my jealousy to affect my normal rest, so I rely on medicine to fall asleep."

"Will taking this drug continuously for a period of time have any adverse effects on the body?" Koshizu Nanatsuki asked with concern, lying down next to Chi Feichi.

Chi Feichi took Yuesui Nanatsuki into his arms and pulled the quilt over him, "Don't worry, this drug will cause far less burden on the body than other sleeping pills on the market."

"That's good," Koshimizu Nanatsuki found a comfortable position in Chi Feichi's arms, "After entering the sin of jealousy experience period, we arrived from Japan to the United States. Then, the time when the sin of jealousy disappears will be based on Japanese time. Will it be calculated in accordance with American time?”

"I can't tell for sure," Chi Feichi felt sleepy and closed his eyes, "I'll find out the day after tomorrow."
