Stay away from Conan

Chapter 45 The Invisible Weapon

When Gao Yuan understood the methods of the secret room, he knew that Suzuki Sonoko was not simply missing this time, but was more likely to have been kidnapped! If it was just a disappearance, even if the police were notified in such a short period of time, they might not be taken seriously, but if it was a kidnapping, the nature would be different.

Therefore, after Gao Yuan wanted to understand this, he immediately secretly sent a text message to Officer Megure and asked him to quietly bring the person over - judging from the current situation, the other party should not have enough time to take the person out of the school, but the person was I still have no clue where to hide it.

However, looking at the two girls from Didan High School, Gao Yuan was a little curious. If this method was used, it could be implemented at any time. Why did he choose to do it today? And today is still the weekend, how can the other party be sure that Yuanzi will come to school today?

Suddenly, Gao Yuan thought of his previous encounter with Yuanzi at the school gate - Yuanzi heard that there would be handsome guys in this kendo competition, so he came to the school specially to watch! And it just so happened that after Sonoko arrived, Kudo Shinichi went back.

kindness? yes! Kudo Shinichi is back!

The biggest difference today is that Kudo Shinichi went back first! As it was a premeditated kidnapping, and the target was a friend of a famous detective, then as the planner of the operation, he definitely didn’t want a famous detective to be present!

But Suzuki Sonoko was kidnapped, and this matter will eventually be known to Kudo Shinichi. So Kudo Shinichi's temporary absence can only help the initial action at most - is this important?

In other words, do you dare not implement this plan while Kudo Shinichi is around? Afraid of being seen through? As long as it is seen through, the plan will fail? If this is the case, then now that I understand the trick of the secret room, should I think of the whole thing a little simpler?

Before, I thought that there might be some accomplices who helped to take Suzuki Sonoko out of the old school building, but it would be too late to send her out of the school. So I called the police over, but I didn't dare to let the police investigate blatantly, because I was worried that Suzuki Sonoko was still in their hands, and if they acted rashly, she might pose a threat to Suzuki Sonoko.

But if we think more simply - could it be that people haven't been taken out of the old school building at all?

Judging from current observations, in this old school building where only the art club has activities today, one entrance and exit has obviously not been opened for a long time, and the other is facing the playground. Even with helpers, it is difficult to take people out, so there are Maybe people are actually still in this old school building! If that's the case, are accomplices really needed?

"Have you inspected all the old school buildings?"

Gao Yuan asked the two girls.

"I've basically searched everything I can, but I can't find Sonoko-san."

Nakagawa Moeme said.

Hearing this, Gao Yuan pretended to be thoughtful, and then said: "Well...that's it. At present, the possibility of Suzuki-san going to other places cannot be ruled out. Nakagawa-san, why don't you go and look elsewhere. Ninagawa-san, please take me to the old school building again."

"OK."

Ninagawa Ayako responded.

"Why don't Caizi go and look elsewhere. I'm familiar with this old school building, so I'll take a closer look."

Nakagawa Moeme said.

"That's okay too."

After receiving the answers from the two of them, Gao Yuan immediately turned around and walked towards the old school building, with his back to the two of them and a smile on his lips!

At this time, the Fujimaru family, Hattori Heiji and Kudo Shinichi had already arranged the facilities in the house and were ready to reenact the case.

"It's begun! Watch out, everyone!"

Hattori Heiji said, putting the baseball cap he was wearing backwards back to the front, then came to the mixing console and started playing music.

The large stereo in the living room was playing loud music, the same music that everyone heard outside the house at the time of the crime.

But after a while, nothing happened.

"What's going on, Heiji? I just heard the music, I didn't hear any strange sounds, and nothing happened!"

Yuan Shan and Ye came up and asked.

"What's going on! This should be the method!"

Seeing that the expected result did not appear, Hattori Heiji was also a little surprised. He put his hands on the mixing table, looked at the various buttons on the mixing table, and said in confusion.

On the side, Kudo Shinichi couldn't help but think about such a result. Then, the two of them thought of something at the same time, raised their heads, and looked at each other.

"That's it!"

Suddenly enlightened, Hattori sighed.

Then Hattori and Kudo walked in different directions. Kudo came to the mixing desk, while Hattori walked behind the wall with artistic photos.

Behind the wall, on the shelves filled with various audio equipment, Hattori found a stereo that was not connected to the power supply, and said happily: "It is indeed like this!"

On the other side, Kudo turned off the music in front of the mixing console.

"Why turn the music down?"

Xiaolan asked with some confusion.

"Well, everyone, let's see it now!"

"The only truth!"

Hattori and Kudo said in harmony, making the two of them look at each other and smile.

Kudo controlled the buttons on the mixer and turned up the volume of a certain frequency band, but everyone heard nothing. But soon, something unexpected happened!

In place of the broken art photo frame, the hostess's art photo frame of the same size that had been repaired suddenly began to vibrate.

"Hey! Another super power!"

Seeing such a scene, Xiaolan couldn't help but think of the live TV broadcast she participated in not long ago.

"Fool! How is that possible!"

Kudo said, "It's about to begin!"

Then the volume of the frequency band was adjusted to the maximum, and then the glass of the art photo frame actually shattered! All the glass shards were scattered on the sofa. This scene shocked both Xiaolan and Heye!

"Why! You obviously didn't do anything!"

Xiaolan asked doubtfully.

"Natural frequency. This is how you make glass break!"

Kudo explained, but some people present obviously didn't understand.

After hearing this statement, Officer Miwako Sato understood the key.

"Natural frequency? Is it resonance!"

"That's right. Everything has its own frequency that is prone to vibrating. The music played in this room has been added with a frequency that will only make the picture frame vibrate."

"In order to make it emit a specific frequency, the speaker that still exists behind the photo frame was modified."

Kudo's follower explained the principle of the incident one after another, but Kazuha still didn't understand: "But I didn't hear anything!"

"Idiot. Ordinary people can't hear sounds above 20,000 Hz!"

Hattori explained.

"The glass on the picture frame is like a swing in the park. The harder you exert it, the harder it shakes."

"Similarly, with the frequency of the characteristic, the vibration of the glass will become more and more severe. When it cannot bear it anymore, the glass will break! The criminal used this invisible weapon to kill Miss Hinodeko."

"And this invisible weapon is resonance!"

Kudo and Hattori spoke one sentence at a time, while Fujimaru Kazuo on the side quickly explained: "Wait! I have never used this frequency! And so far, this piece of music has never shattered the glass!"

After hearing this, Hattori couldn't help but smile, "Of course! The person who knew that you would use this song to cover up your affair made a CD with a specific frequency added to it! That's right, Toui-ryu!"

"That's right! The culprit is you!"

Saying that, Kudo and Hattori pointed at the prisoner at the same time—Fujimaru Yoshino!
