"No one was tampering with the dead, but because this study created an atmosphere of extreme oppression for Tatsumura." Okata looked at Megumi and said slowly.

Kudo Shinichi frowned slightly: "The atmosphere of extreme oppression?" His eyes swept around the study and found no things that could be connected.

Okabaya walked to the front of the desk: "The entire study is closed, just like what you reasoned, it is a secret room, and a execution ground where many factors can be gathered together. We see that the deceased's desk is displayed with books and office supplies he usually uses. But if you look closely, these stacked books are neatly arranged in front of the deceased. Shinichi's reasoning mentioned that it was used by Mrs. Tatsumura to cover up the pain of the deceased's expression once she woke up. The basis for the reasoning is that these books were taken down from a certain position on the bookshelf at the same time. I'm right?"

Kudo Shin nodded. In the process of reasoning, he mentioned that in order to cover up the deceased, Mrs. Damura used these stacks of books directly taken off the books shelf to block everyone's vision, and could not see the deceased's expression from the opposite angle.

"The experiment I mentioned just now is very novel and incredible, but there are two points mentioned here. One is that the human heart is extremely fragile, so it will be very sensitive to the pressure applied to anything. The other is that when the pressure is applied, once there is periodicity, it will increase the resistance of this sense of oppression to the function of the schizophrenia."

"So let's think back to what we caught in addition to these when we first entered this study?"

Ogata looked at Hattori Heiji with a serious expression, and Kudo Shinichi who was in the middle of thinking. Meguro and other police officers later arrived at the scene of the crime, so they were more waiting for the answers he said.

Kudo Shinichi suddenly looked shocked, his eyes looked at Okata, and his glitter flashed: "Are you referring to the melody played by the speaker?"

"Melody?" Hattori Heiji also came to his senses, his heart was thrilled, and he looked at the high-end speaker placed in a window next to the bookshelf in shock.

Okata confirmed Kudo Shinichi's guess and said, "Yes, the first impression we stayed when we first entered the study was not the decoration layout in this room, nor the deceased was relying on the office chair and the high-power amplifier, even through a wooden door, which could be heard clearly."

"But the audio is on, just like the books listed on the desk, to cover up the deceased when the poison needle pierces his body, right?" Hattori Heiji said in confusion.

"Mrs. Tamura's motivation to turn on the audio and amplify the volume loudly, creating such mixed sound scenes is indeed a cover-up for her murder plan. However, in this process, there are changes that deviate from the trajectory."

Okara walked towards the audio and continued, "Madam Tatsumura, do you know what type of music the deceased usually like?"

Upon hearing this, Mrs. Damura was stunned and thought hard: "He listened to opera more often."

"As you said, the dead likes opera more, so in the disc boxes next to the speaker, most of the classic operas I see are passed down from all over the world. So you made a mistake, just like casually pulling out a row of books from the bookshelf to cover it up, you picked a disc that the dead would never listen to and put on aside."

After Ogata finished speaking, Mrs. Tamura explained: "When I arranged these things, my mind was very confused. Although I was as careful as possible, I still found many clues by you."

Meguchi looked at Okata: "But is there any direct reason for the death of the deceased and what kind of discs are on the audio?"

Ogata stretched out his hand, took off his gloves, and gently pressed the switch of the speaker: "Sound is generated by the vibration of an object. It propagates in the form of waves and can be moved by any substance. When the sound wave vibrates the listening bones of the inner ear, these vibrations are converted into tiny electronic brain waves, which are the audio we finally capture. Music is the sound that has been processed, so different effects will be produced in different types. For example, light music, melodious and soft melody, listening in a quiet environment will make you feel comfortable body and mind, relaxed, and constantly release pressure."

"But on the contrary, percussion music with strong rhythms or heavy bass with a gradual melody are close to low-frequency noise! ​​Low-frequency noise does not cause functional damage to the human body, but may also cause organic damage and a sense of pressure on the heart. Therefore, some people in bars or KTVs, when the audio has heavy bass fluctuations and progresses with the melody, the chest becomes obviously stuffy and short breathing. This is because the audio continues to pressure the heart. If these pressures reach the critical point, it is the same as the principle that coin presses the chest and causes death, which will cause the normal person's scheming function to collapse instantly."

Heiji Hattori heard this for the first time and tried to write it down with his head because this is knowledge that he would not talk about in the textbook.

In his eyes, Okata's image continued to magnify.

His original disdain, and his admiration and respect now, made him feel that a forensic doctor can do this, completely subverting his cognition.

After Ogata pressed the audio switch, he used the back function to quickly rewind the disc placed inside for about twenty-five minutes, which is the melody he heard during the period after the autopsy.

"The discs played by Mrs. Tamura are not operas, but special melodies mixed between symphony music."

After saying that, Ogata stood aside and stopped talking, allowing everyone to listen to the rhythm of the discs coming out through the audio amplifier.

Hattori Heiji, Kudo Shinichi, Meguro and Mouri Kogoro, they all pricked up their ears and listened seriously.

Because according to Okara, the real cause of Damura's death is related to this rhythm.

At first, the rhythm of the music was like a trickle of water, gentle and delicate. Everyone would feel their nerves slowly ease through simple auditory processing, especially for girls like Xiaolan, who sounded like a pleasure.

Sounds can create pictures, and they seem to foresee many beautiful dreams.

The wooden windows in the entire study are closed, so the sound effects are very realistic and gathered together, especially near the desk.

But when the music started for about half a minute, the melody suddenly turned and became a little sad, a little melancholy and sad. It sounded like people were brought into the mood. From the comfortable nature, they came to the confusing and painful alley. They could not find the end or the exit.

Hattori Heiji's face changed. Is this melody?

People like Meguri and Kogoro Mouri who don’t understand music also think this song is a bit weird and indescribable.

When the notes and tones were significantly promoted, as if the waves were waving, the first time the audio rose, the whole music became tragic and tragic. There was a feeling of making the hair stand up all over the body and the mood fell.

Okara has practiced piano, so no one knows better than him what the magic of this song is.

Kudo Shinichi's face changed. As the rhythm rose, his expression was painful, and his body even reacted, getting closer and closer torture.

Koran, Kaneki Sakiko, and Mrs. Tatsumura, would never feel that this was a pleasure again.

They felt that every time this song changed, their chests would be stuffy, and their whole heart was suspended in the air, immersed in endless sorrow, mourning and despair.

Ogata turned off the sound, the entire study room instantly quieted, all the melodies came to an abrupt end, the nerves were originally tense, and the worried people were relieved.

Silence for a moment.

Megu asked first, "Brother Okaga, what is this hell of music?" He had never heard of it. There was such a strange rhythm in this world that would make the body feel so uncomfortable.

If it weren't for this case, perhaps everyone present would never understand the horror shaping nature of music.

"Forbidden Song." Okara opened his mouth and replied slowly.

"Forbidden Song?" Memu was stunned.

It is easy to understand the meaning of these two words, but what extent is it prohibited?

Hattori Heiji's eyes flashed under the brim of the hat on the side, and he asked, "Which of this is the three forbidden songs?"

He had never learned music, but when he heard this unpleasant rhythm, he could easily think of three banned songs that he mentioned in a book introduction that were prohibited from circulation among countries.

"Black Sunday!"

This is also the second time Okao heard this song in a sense. The first time he was curious and collected in black markets during his study in the United States. After listening to it once, he felt that the style of the song was heavy and depressing and was placed in the collection.

From the times to the 21st century, audio files that can be found on the Internet have been deleted and modified and rhythmized. Therefore, Yu Fang made it a precious collection.

Most people didn't hear it and showed surprise.

"The name of this song is Black Sunday, and it is one of the three most powerful songs in the world."

Okabaya paused and explained in detail: "It was born in France in 1932, but unfortunately it was destroyed in 1945. The reason is that this song, called "The Devil's Invitation", caused more than 100 listeners to commit suicide after listening! The suicide note left by the suicide note said that suicide was because they could not bear the melody of sadness."

"There are countless guitarists, pianists and other artists here who have played this song and then sealed their hands. Its melody is a huge sorrow that humans cannot bear. It can cause your heart to die. That melody is like a dead person singing and a dead soul playing."

Exaggerated, but realistic.

Memu said in horror: "Then is the truth about killing Tatsumura?"

Only when you feel it when you are in the scene can you realize that the credibility of music killing has risen sharply.

Ogata did not comment, but came to the desk in the study and sat in the chair on which the dead body was leaning on: "If this song is explained from a scientific perspective, it is the same as the coin experiment I mentioned before, because every cycle after the down-tuning cycle will suddenly increase the audio, so that the person who hears it feels the pressure of the heart."

"This phenomenon of raising audio has reached 13 times, but to make the living person have a cardiac arrest and achieve the purpose of killing people, other factors in the study need to cooperate."

Okata sat from the perspective of the dead, observing everyone and everything in the study.

Megu didn't mind sitting. He was so hung up that he said in confusion: "What is it?"

"The deceased's sitting posture was the same as I am now, supporting his side face with his arms." Okata imitated the sitting posture that the deceased Tamura Moto maintained when they walked into the study.

"If you think about it, the deceased's palm is completely attached to one side of the ear, and the elbow serves as a support point to balance the head that comes over."

Everyone saw Okara slowly adjusting, supporting the ears above the face with one hand.

"Xiaolan, help turn on the speaker."

Okabata said softly. (To be continued. Please search for Astronomy, novels are better, updated and faster!)
