There was silence in the living room of Nanahara's house for a long time, and Nanahara Takeshi and Kiyomi Ruri were both immersed in their respective thoughts for a while, and in the end, Kiyomi Ruri spoke first. She took a small bite of the meatball, forcibly lifted her spirits, and asked Nanahara Takeshi, "Then how is this incident connected to Grandma Bikawa's 'Prophetic Dream'?" ”

She sympathizes with Atsushi Kameda, in just twenty minutes, it seems that she has watched a life movie, and she can feel the sadness of an ordinary adult who is so desperate that she cries bitterly, but she is just an ordinary first-year college girl, and her head is still stupid, even if she sympathizes, she can't do anything, she can only clean up her mood and continue to explore the truth.

Nanahara Takeshi also came back to his senses and sighed while eating: "That was purely an accident, Atsushi Kameda is indeed unlucky." ”

"Why do you say that?"

"He intends to leave a sum of money for his wife and children, and at the same time take revenge on Aiura Jimitsu who ruined his life, and he has already begun to prepare." Nanahara Takeshi said slowly, "He went to Aiura to have a fight, and the two sides had a physical altercation, so he got Aiura's hair and stole his glasses, and by the way, he secretly recorded the sound with a portable device such as a small tape recorder, and was going to use it to synthesize the live sound when Aiura 'killed' him, but he was unlucky, and the tape was stolen just after synthesizing." ”

"Stolen?" Ruri Kiyomi recalled the scene, "His cheap little apartment was stolen? ”

Nanahara Takeshi nodded and said: "It's a fledgling little thief, who picked the lock of his small apartment, probably trying to find some property, but I didn't expect Kameda to be poorer than him, so he could only take away the dual-card recorder, portable tape recorder and all the tapes that were still worth a little money." These devices were originally used by Kameda to synthesize the sound of the 'homicide' scene, the first half was secretly recorded when Kameda was arguing with Aiura, and the second half of the begging for mercy and miserable sound were matched by Kameda himself in the later period, so the little girl in the neighborhood could hear him arguing with Aiura, and that was the effect of his audition, so the door lock of the apartment was new, and he had to change the door lock when it was broken, so as not to accidentally attract the police. ”

Kiyomi Ruri suddenly realized, and also remembered these details, and asked, "And then?" ”

Nanahara Takeshi said: "Kameda has no choice, the plan must be executed, so he can only buy a small tape recorder for the second time, go to Aiura again, and have a physical conflict with him to complete the secret recording, and then re-synthesize the audio tape in the cheap apartment, but this time he really doesn't have the money to buy a dual-card tape recorder that can record on dual tapes, so he can only make up a reason to move the very bulky old-fashioned dual-card tape recorder at home, which is the one that was placed in his bookcase before, After using it, he gave it directly to the little girl in the neighborhood who helped him for free in the last stage of his life. ”

After a pause, he added, "Actually, he should have destroyed that dual-card recorder directly, but ...... Probably he is a good person, I really want to thank the little girl next door, the small tape recorder he also uses to fake the sound of the murder scene, everything else is some rags, so I can only pick up the bulky dual-card tape recorder that seems to be able to help the little girl next door as a thank you gift. ”

I see......

Kiyomi Ruri thought for a moment, and felt that all the reasoning that Nanahara Takeshi said could be linked to real things, and there seemed to be nothing that could be leveraged, and after Nanahara Takeshi said this, she could make up Kameda Atsushi's crime plan, and felt a pity in her heart, if Nanahara Takeshi thought about it later, maybe she could also reason.

It's a pity, it's so simple.

She didn't speak for a while, Nanahara Takeshi glanced at her and continued: "He has been in a hurry, and he quickly completed the second recording and debugging, and was about to be 'killed' by Aiura, but it was still a little late, and at this time, the tapes and tape recorders that were stolen for the first time had already been sold by thieves at the flea market and exchanged for money, and it just so happened that the tapes were bought home by Mrs. Fu Meijiang. ”

When Kiyomi Ruri heard this, she suddenly opened her mouth wide: "You mean ......"

Nanahara Takeshi smiled, "Yes, that tape is in your room right now. ”

Kiyomi Ruri didn't hesitate, got up and rushed to his house, and it didn't take three minutes to come back with the box of second-hand sundries, and Nanahara Takeshi had already taken a small and delicate dual-card internal recorder from the study and put it on the small square table.

Kiyomi Ruri rummaged through the glove box and asked anxiously, "Which plate is it, do you want to listen to it all?" ”

Nanahara Takeshi pushed her to the side and began to rummage through herself, "No, we actually met, it was in the card slot next door to Yoshida's ballad, and he was afraid of making a mistake on the AB side, so he would definitely make a mark...... Oh, I've found it, it's this plate. ”

He took out the tape and continued while putting it into the tape recorder, "Atsushi Kameda used to have a tape recorder, and he would definitely listen to the song and buy some tapes, this is what he bought before, and then he was going to frame Aiura, so he took these tapes from home, washed them off and re-recorded them, but the content he needed to record was only two or three minutes, so the ten minutes that were washed out were enough, and even the other side was still the original song." ”

As he spoke, he installed the tape and pressed the play button, and the tape recorder made a low "rustle" sound, followed by a reprimand from a strange man, presumably the voice of Osamu Aiura. The content of the next two or three minutes is basically the same as the "prophetic dream" of Mrs. Fu Meijiang, the two men go from arguing to fighting and then to scuffling, but there are slight differences with the testimony of the fishermen, and there are many words that do not match.

After the tape was put on Atsushi Kameda and let out a terrible scream, the tape recorder returned to the sound of "rustling", which rang for seven or eight minutes, and then Takuro Yoshida's song sounded again, and Takeshi Nanahara, who casually turned off the tape recorder and said softly: "That's why, the old lady Fumie heard the tape before Atsushi Kameda died, so she had a strange prophetic dream." Now that this tape is in our hands, we don't have to worry about her going wrong again. ”

Kiyomi Ruri let out a long sigh of relief, it turns out that this is the case, she has long felt that there is a problem, it is obviously the world of science, how can there be any superpowers, everything can make sense now...... It's not close.

She immediately asked: "Grandma Bichuan had three nightmares, each time with an interval of one day, and each time it became clearer and clearer, could it be that she took the initiative to listen to this tape three times?" It doesn't make sense, she didn't notice a problem, right? ”

Nanahara Takeshi smiled a little helplessly: "Yes, she listened to it three times, but she really didn't find out."

Kiyomi Ruri couldn't understand it: "How is this possible? ”

Nanahara Takeshi pointed to the tape in the small dual-card tape recorder and explained: "The working principle of music tape and video tape is basically the same, but the difference between the two is that the video tape is one-way, and the entire tape is coherently recorded with audio and video information for the video recorder to read, while the music tape is bidirectional, divided into two sides, AB, and the audio information recorded on each side only accounts for half of the width of the tape." ”

Kiyomi Ruri didn't understand it too much, music tapes were common, but she didn't understand how this thing worked, and asked hesitantly, "So, what's wrong with this?" ”

Nanahara Takeshi pointed to the dual-card tape recorder and smiled: "So if its reading tool is an ordinary tape recorder, you put the tape in, it will be driven by the only drive tooth to start walking the magnetic stripe, let the head start to read the information, and when the A side turns to the end, its play button will pop up, let you turn the tape over, so that it can read the B side again."

But Mrs. Fu Meijiang uses an old-fashioned dual-card recorder, which was used by music enthusiasts in the past, you can put in a music tape and a blank tape at the same time for internal recording, you can only copy the tape information, not affected by the surrounding environmental sound, and if you just play music, it will wait for the tape of the first card slot to finish, and automatically play the tape of the second card slot, so this will happen. ”

Nanahara Takeshi filled the tape recorder with two tapes as he spoke, and pressed the fast-forward button to play, the A side of the first disc was broadcast, and the A side of the second disc continued to be broadcast, but at this time there was the sound of Aiura reprimanding Kameda, here Nanahara Takeshi released the fast-forward button, and let Kiyomi Ruri listen, but after two or three minutes, this synthetic recording disappeared, and there was another "rustle" sound, and then Nanahara Takeshi slightly fast-forwarded and then sounded a soft and soothing singing, and the last two A sides were played, and the tape recorder play button automatically bounced.

But Nanahara Takeshi didn't turn the tape over, pressed the play button again, and the second drive gear of the dual-card tape recorder rotated, so that the magnetic stripe of the tape began to go backwards again, and the music tape didn't need to be turned over to start playing the B side directly, he continued to fast forward, and after two consecutive B sides were played, the play button of the tape recorder automatically bounced up again.

He explained while operating: "This kind of dual-card tape recorder is different from ordinary tape recorders, it has two drive gears in each card slot, one is responsible for forward rotation, one is responsible for reversing, no need to turn over to record and play the complete tape, it was a very advanced technology back then, it is a family blockbuster, so Mrs. Fu Meijiang doesn't have to do anything, she just needs to press the play button every day before going to bed, you can have nightmares." ”

Kiyomi Ruri finally understood, but still opened her mouth wide in disbelief: "It's that simple? ”

Nanahara Takeya smiled helplessly: "Yes, it's that simple." Mrs. Fumie probably has a bad habit of listening to some music and reading magazines before going to bed, and she fell asleep on the first night listening to the A side of the first tape, and when the second A side was played, she heard the dispute and fight between Aiura and Kameda in a daze, but because she wanted to sleep, she was afraid of noisy granddaughters, so she kept turning on the tape recorder quietly, and it didn't wake her up completely, but it just gave her some vague memories, and she fell back into a deep sleep after just two or three minutes, and Kameda Atsushi was Jiguang Aiura in the afternoon of the next day. Kill', so her dream became a prophetic dream.

I had this strange dream, and the old lady got up in the morning and entered a state of self-doubt and fear, and went to the shrine that day, but even if she went to the shrine, her nerves were still nervous, and she was over seventy years old, and she would get tired quickly, and at night according to the old habit she pressed the play button and went to sleep, and the next night because she listened to the B side, nothing happened.

On the third day, she relaxed a little, but self-doubt and fear were still a little bit, not completely relieved, and she didn't want to listen to the song that day, eighty percent of them had been thinking wildly, only before resting at night, and pressed the play button casually according to the old habit, and didn't think about changing the tape, she just wanted to relax and sleep well, and she was sure that she had just had a strange dream by accident before, but that night she heard the dispute and fight between Kameda and Aiura in the A side in her sleep, and had a nightmare again.

This time she was completely panicked, and told her granddaughter Mariko Bikawa, and the two of them ran to the shrine together, and at night she was restless, and she was in no mood to change the tape at all, so she pressed it casually and wanted to listen to the song and sleep well, and so on, it was okay to listen to side B on the fourth day, and had nightmares when she listened to side A on the fifth day.

At this time, even Mariko Bikawa was a little panicked, and hurriedly went to Miss Nakano to verify, and came to us that night, and never went back to live, so Mrs. Fumie didn't have to do nightmares if she wanted to, but she was actually safe. ”

Kiyomi Ruri was stunned, no wonder the old lady had a nightmare on time every other night, it was very weird, like a supernatural phenomenon, it turned out that she just bought a dual-card tape recorder that was too advanced, it could be broadcast continuously, and it could also be turned over automatically by dual drive, and it had been listening to it in a loop on the AB side, which made it a pit for herself.

Damn, if I had found out a little earlier than this guy that Kameda-san was committing suicide and that his small apartment had been stolen, and I knew how the old-fashioned dual-card tape recorder and music tape worked, I could have guessed ...... No, I can reason about it.

It's a pity, why is it so little bit worse every time!
