Tan Zhi looked very excited. Aze calmly analyzed the last sentence she had just said. She spent 5 years collecting information on the tragedy of the fifth middle school? Didn't she join the film crew for a high salary? Who is she? She is able to deduce the truth of events from small things. Since the last time he saw her on the rooftop, he deduced the cause of Deng Xin's death by jumping off the building, and he faintly realized that the woman in front of him was not as simple as it seemed on the surface. "The sound analyst is just a swayer, what is your identity?!"

Tan Zhi saw that the matter could no longer be hidden, so he had to take out his documents and hand them to Aze. "The Xing Investigation Serious Crime Team ------ Dai Tan Zhi."

Aze handed her back the papers, staring into her eyes.

After a long time, he spoke: "I gave you the sound file, you open the fourth gear." ”

Tan Zhi quickly switched out the sound file in the computer.

A small voice came from the player......

(Please...... Come and save me...... The teacher is here! My classmates were all killed...... Please come and save me...... Feed? Feed? Can you hear what I'm saying? Feed?! ）

(Lost handkerchief......

Throwing away the handkerchief......

Gently place on the back of the little one......

Don't tell her......

Hurry up and catch her......

Hurry up and catch her...... ）

This is a recording of Qin Qin when she asked the police for help at the moment of the incident. This is the only Qinqin word used by the police. I can't accept that the police blame Jiang Yuanmei for the whole thing. Qin Qin faced the situation alone and didn't know how frightened she was. I really want to crack this case. Ms. Tam Chi...... In fact, I was also a police officer five years ago, and I also took over the tragedy of the Fifth Middle School. It was only halfway through the investigation of the incident, and the members of the group were injured and self-harmed one after another. In the end, the superior issued a document to transfer the case to another team for handling. I also resigned because of this...... At that time, the situation of the crew was the same as that of the current film crew, even the wounds were in the same place. We also met a girl at that place at almost 12 o'clock that year. Aze's expression was very painful, and those dusty memories of the past were like a wound that was about to scar and be torn open again.

Tan Zhi didn't expect Aze to reveal his previous identity. Back then, she did hear that the police officers investigating the No. 5 Middle School were evil, and the whole city was in turmoil.

Aze then spoke again: "I didn't expect that the case I took over back then would happen to me again. I have to wonder if there really are undead in the world. If it weren't for that, why would I step into the women's fifth middle school again, get the "Lyrics Commentary" again, and meet that girl again......"

"You know that girl?"

"Well, I know, she lives in Room 1204, No. 43, Dongpu Street, South of the City. She committed suicide by jumping off a building five years ago, and according to the investigation, she was three months pregnant at the time. ”

"Is this related to the tragedy of the fifth middle school?"

“…… I don't know. At that time, we only found out that she was Qin Qin's classmate in junior high school, and Qin Qin was also transferred to No. 5 middle school because of her. ”

"So, what's her name?"

Fan ...... Sweet...... Sweet. ”

"This case is full of mysteries about sound, which is why I applied to Mr. Dai for help from the sound research institute. The mystery of the sound, the student ------ Shanshan, who disappeared at the end, also had auditory hallucinations of "Flowers Bloom". In order not to be affected by the curse, she used the method of reciting the lyrics of Auditory Hallucinations Jin upside down. Maybe we can also do an experiment with song retrograde in a music classroom. ”

“…… Song retrograde? ”

"Perhaps...... It's too dangerous to do that. Aze saw that Tan Zhi's face was difficult, so he immediately changed his words.

"No, that's not what I meant. I'm just wondering why I hadn't thought of this method before. ”

"I looked up the song "Flowers Bloom" in "Lyrics Commentary". It turns out that there is an explanation that the song has the power to open the door to the afterlife and guide the dead to the ghost town. ”

Tan Zhi's eyes flashed with light, as if he realized something: "Could it be ...... Ruan Qinqin also entered the world of lyrics like Shanshan? Because I understand the hidden meaning of the etude and the case and the causal relationship too much, I ......"

In fact, she, like Qin Qin, has been investigating those sound files since she took over the case of the women's No. 5 middle school. She didn't feel out of it at all. Every time she heard those sound files, the space would immediately change to the scene at that time, and she could even clearly feel the terrifying aura surrounding the victim. The reason why Qin Qin has auditory hallucinations and hallucinations may be because she wants to forget the painful memories of the past.

Tam Chi deeply understands the pain of being troubled by sound spirits, because her hearing is different from others, and she can hear sounds that cannot be heard by human ears. In the past, she was bullied by her classmates and rejected by the school, and even her relatives looked at her with special eyes; Think about it, who wants to get along with a psychic person?

The case of the women's No. 5 middle school is not as simple as it seems, whether it is for Qin Qin, for the dead students, or for Jiang Yuanmei, who absconded in France. She actually took over this case, and she must find out the truth.

Tan Zhi finished debugging the sound measuring instrument and picked up the music draft of "Flowers Are Blooming".

No one knows what will happen if the lyrics are sung upside down in this music classroom.

"The flowers are blooming...... The flowers are blooming ......"

……

After singing the lyrics upside down, Tan Zhi found that the data map displayed by the instrument had changed significantly, and she felt that the breath around her was slowly changing...... She really wanted to know, in this music classroom, what did the survivor Ruan Qinqin see here?! The reason why the police put the missing Jiang Yuanmei into the scope of suspicion is that there is really a basis or do they want to hastily solve the case? Why? Could it be that there is a big secret hidden behind this case?!

Tan Zhi said that he would go to the music classroom alone to do a voice test, and Aze also wanted to go to the dormitory where Qin Qin lived again, maybe he could find new clues.

In fact, he doesn't believe that there are supernatural things in the world, but since he took over the case of the fifth middle school of women, strange things have happened one after another. At that time, because the colleagues in charge of investigating the case had accidents one after another, the superiors had to hand over the case to another team. Now the camera crew is in the same situation.

Is there really such a coincidence?

Standing by the window, Aze felt a little dizzy. Strange to say, there is no wind in this dormitory, but he always feels that there is a wind behind him that blows him cool like cold air. It was as if the coldness had penetrated through the skin and directly into the bones.

"Hee ......"

What was that?

Did he hear it wrong?

"Don't ...... Yes! ”

When Aze walked out of the dormitory where Qin Qin lived, the previous voice also disappeared. If he hadn't stayed awake, he would have thought that what he had heard earlier was just a hallucination. But...... Where did those voices come from?

I once remembered that Tan Zhi said that where the eyes can't see, sound will also be transmitted through the echo effect.

…… Could it be that the voice heard earlier was left by the deceased before he died?

Aze suddenly thought of Tomita in the music classroom, and shouted in his heart that it was not good!

He was really careless, how could he let her stay alone in such a dangerous place!!

Aze's footsteps echoed through the long hallway.

"Boom...... Cha....... Click......"

(Click....... Cha...... Click...... ）

Why are there two echoes?

He jerked his head and seemed to see a dark shadow flash by quickly.

Aze swallowed his saliva and moved towards the black shadow in small steps: "Who! Who is there!!". He hurriedly took out a flashlight and shone it over. I saw the white curtain-like cloth fluttering in the wind.

It turned out to be just a false alarm. Aze quickened his pace and ran downstairs, suddenly remembering that there could be no curtains in the hallway.

That...... What did he just see?!

The school building, which was already in ruins, was even more dark and terrifying under the darkness of the night. It stood in front of the trees in pitch black. The playground overgrown with weeds makes a sparse sound from time to time under the night wind. The music room was lit up with white light, and from a distance it looked like the eyes of the devil, looking coldly at the people who were suffering from headaches for the case.

"What a hell of a place!" Aze couldn't help but curse. Strode towards the music room.

Before I arrived, I heard a melodious piano sound coming from the classroom. Aze couldn't help but chuckle, Tan Zhi was still in the mood to play the piano, but he was worried about her safety. He wanted to hide his intention at the moment. So he dismantled and walked back.

Just as Aze turned around, a black figure flashed behind him again.

No! It's not a flash. To be precise, it should be floating.

He knew that the shadow was the same thing he had seen in the dormitory building earlier, and that it had followed him. He didn't even notice that it was following him all the time!!

"Miss Tan Zhi!" Aze didn't understand why his first reaction was to call out her name.

The shadow paused and continued on its way. Finally, it stopped at the door of a classroom with fluorescent lights on.

Aze looked up and saw an iron plaque nailed to the wall at the door, which read------------ Music Classroom.

Aze pushed the door open and entered.

It's strange that there wasn't even a single person inside.

(Hee~~~)

That burst of laughter came again. The source of the sound is behind him. Along with that burst of laughter, there was also that cold wind that was cold to the bone!

Aze was sure that the dark shadow was standing behind him at the moment. For the first time in my life, I felt fear!

Suddenly, a hand was placed on his shoulder. He reflexively turned his head......

"Miss Tan Zhi...... Are you okay. Aze finally breathed a sigh of relief.

Suddenly, a bright light flashed in front of Aze, and he saw that Tan Zhi's beautiful face had become so gloomy, and he couldn't even tell whether the woman in front of him was Tan Zhi or another woman he had never met.

"Miss Tan Zhi!"

No matter how Aze called, Tan Zhi held the knife and desperately pounced on him as if he was being manipulated. Aze realized that if this continued, no one knew what would happen.

"Ahh Qin Qin!! Aze yelled behind Tan Zhi in a hurry. Strange to say, Tan Zhi, who was originally fierce and distorted, was stunned for a second after hearing Qin Qin's name. He took this opportunity to rush forward and snatch the knife from Tan Zhi's hand and slam her to the floor.

"Hmm...... It hurts......" Tan Zhi got up from the ground and rubbed his aching buttocks. What the hell happened to her? She remembers doing a sound experiment before...... Then he noticed that the sound wave on the instrument had changed, and he was about to inform Aze when the old piano in the corner of the music room started playing itself. She felt an aura coming at her, and she tried to run out, but the door couldn't be opened. Next...... It was now that I saw Aze panting and looking at her with a solemn face.

She reached out and rubbed her aching temples, "I...... What exactly was done? Just...... What the hell is going on? ”

Seeing Tan Zhi's troubled appearance, Aze couldn't bear it. So he walked over to her, but unexpectedly saw Tan Zhi's eyes wide with fear, and he suddenly realized that the thing should have appeared somewhere behind him again!

I used to hear old people talk about it when I was a child. If you bump into something that's not clean, keep your composure first, as long as you can't see their presence, they'll disappear naturally.

Five years ago, Aze also used this method to pick up a life and come back.

"Anyway, you're fine, I've checked the lyrics annotation for "Flowers Are Blooming". In the lyrics, the lotus flower refers to the alleviation of the pain in the heart, and if it is sung in reverse, there will be a manifestation that is contrary to the meaning of the lyrics. There is nothing in this place, let's go home early. ”

Tan Zhi was now somewhat subdued by Aze's composure. You must know that at this moment, there are more than a dozen girls standing behind him covered in blood and wearing student uniforms! It's certain that they only appeared when they heard the song "Flowers Are Blooming".

Tan Zhi saw Aze looking at her and told her to leave quickly. She was smart and immediately understood, and followed Aze's footsteps as she spoke. "I was testing the song in the music room when I heard singing from somewhere else. When I came back to my senses, I switched back to being bullied as a child. ”

The two walked out of the teaching building flatly, and their feet seemed to have run for more than ten miles, and they couldn't lift their strength at all.

Strange to say, the undead who were originally following Aze have disappeared.

Is it really because you pretend not to see the undead that they disappear? Or are the undead staying in that music classroom? Why be there? Could it be that there are important clues there that can solve the mystery of the whole case?!

"When I was first in the dorm, the songs you sang in the music room sounded like they were singing in my ears. It seems that there are many mysteries about this school. If the late-night singing has anything to do with the case five years ago, the center of the whole incident is the music classroom. Aze said what he thought, "Perhaps...... There will be danger, but I still need your help. Those so-called speech spirits should only be for people with normal hearing, right? ”

After Aze said it, Tan Zhi remembered that she chose the job of a translator because she turned her ear barrier into a weapon, and she didn't have to be afraid of those words at all!

When the two were silent, they heard Mr. Dai's voice coming from behind: "Are you both here?!" ”

Tan Zhi's attitude towards Mr. Dai is still the same, as if there is some hatred. It was Aze who opened his mouth to break the silence: "Mr. Dai?!" Didn't you stay in the hospital? How to ......"

"Qin Hui didn't have anything out of the ordinary. To be on the safe side, I arranged for someone to stay and take care of her. The other team members are also on holiday and waiting for the notice. How? You two don't want to rest yet? Mr. Dai noticed that there was a difference between Aze and Tomita, but he couldn't say what the difference was.

"Mr. Dai, won't this be a problem?" Yao Ze asked with some concern.

Tan Zhi has been working with him for some time. It was the first time she had seen Aze with such a solemn expression, could it be that he still cared about Qin Hui? But it seems that there is something else going on.

Aze was worried about Qin Hui's safety, because Ruan Qinqin's psychiatric nursing home was very close to the hospital where she lived. When he saw Mr. Dai come back to No. 5 Middle School alone, his heart shook inexplicably.

After all, Mr. Dai will not let his subordinates go.

"Aze, for the sake of the fact that you have been busy with me for so many days, I will invite you to dinner. Let's go. After Tan Zhi finished speaking, he turned around and walked in the direction of the park.

Aze glanced at Mr. Dai. He knew that Tan Zhi always seemed to have a lot of opinions about Mr. Dai, so it was not good to ask Mr. Dai to go with him at this time. He just nodded politely, "Then let's go to dinner." After speaking, he quickly followed Tan Zhi out of that strange place.

After Aze got into the car, Tan Zhi stepped on the accelerator and drove in the direction of the hospital. Tan Zhi is a very calm woman, but now it seems that she is in a bad condition.

The car stopped at the entrance of the hospital.

A cordon has been drawn at the entrance of the hospital, several people in police uniforms are maintaining order, and men in white robes are squatting on the ground to collect blood samples. On the other side, a man in a police uniform was recording statements from several nurses.

The crew of the film crew was also there. When they saw Tan Zhi and Aze, they immediately ran over.

Tan Zhi had a bad premonition.

"Mr. Dai is dead."

As soon as Tan Zhi heard this, his face instantly turned bloodless, and his mouth felt like he had been hit hard. She controlled the tears that were about to flow from her eyes and walked towards the place where the cordon was pulled.

Aze followed uneasily.

The report came out that Mr. Dai fell to his death from the 7th floor of the hospital ward at 12 p.m. In addition to the drug ingredients found in the nails of the deceased, mainly coterine phosphate and ephedrine hydrochloride, these may have been left on the nails because the deceased had used cough spray drugs before his death. No clues could be found at the scene of the crime, and the police concluded that it was a suicide case. Tan Zhi didn't believe in such an answer, because Qin Hui was also missing.

"Miss Tan Zhi, I want to ask a question." Aze didn't understand that Tan Zhi, who had always seemed to be extremely disgusted with Mr. Dai, knew that Mr. Dai was more haggard than anyone else after the accident.

Tan Zhi raised his bloodshot eyes, and his voice was a little weak: "Do you want to ask me what is the relationship between me and Mr. Dai?" He is my father and the only relative I have in this world. ”

"I'm sorry." Aze couldn't think of anything else except for this utterly vulgar line.

"Let's go, it's time to meet up with friends." Tan Zhi got up and walked out.

Aze strode after her. Although Tan Zhi only said her relationship with Mr. Dai in a soft word, as the only relative in the world, she must be very sad in her heart, why wouldn't she show vulnerability like other women? Seeing her like this made him a little uncomfortable.

Tan Zhi looked at the white house through the iron railing, speechless.

Qin Qin, how many secrets are hidden in you? It's time to speak up, right?!

"Miss Tan Zhi, why did Yang suddenly come to the Liao Nursing Home?" Aze didn't understand what Tan Zhi was thinking.

Without waiting for Tan Zhi to answer, the middle-aged white-robed male doctor greeted him last time.

"You're coming to see Qin Qin again?"

"She, is she okay?"

"She disappeared the night after you left, and when it was dawn she sat there quietly for hours without moving. This has never happened before. This kid is really worrying. ”

Tan Zhi looked at the thin figure sitting in front of the window through the glass door. When her eyes touched the doll thrown on the ground, a charming smile appeared on her face, "Doctor, it seems that Qin Qin doesn't like the toy I gave her very much, I think it's better to let me take it back." ”

What else did the doctor want to say, but Tan Zhi had already pushed open the door and picked up the doll. When her hand touched the doll, a smile rose into the corner of her mouth.

After leaving the Liao Nursing Home, Shaanxi Province couldn't wait to ask: "Miss Tan Zhi, what were you laughing at just now?" ”

"I'll talk about it later."

Tan Zhi cut a hole in the doll's head, and then reached out and took out something the size of a button from inside.

That's a miniature recorder.

It was assembled for her by her father, Mr. Dai, before his death. When her mother died, her father didn't see her mother for the last time in order to catch up with the news, so Tan Zhi kept digging into the horns, always thinking that her mother's death was caused by her father's neglect. It wasn't until her father died that she realized that she was like a child. She knows that regret is useless, and the only thing she has to do is find out the truth.

The entire tape from the feat to the end was only Qin Qinyi's cry and the sentence "I'm sorry." "And, of course, the sound of subtle footsteps and the slight sound of coughing.

There's a reason why Tan Zhi wanted to put a voice recorder in this doll in the first place. She did suspect that Qin Qin was the murderer. She has also taken on homicide cases before, and the murderer used bitter tactics to cover up people's eyes. Qin Qin was the only person who survived the tragedy of the Fifth Middle School that year, and Tan Zhi had never been able to figure out this. Although she is now a person of low intelligence, she is still alive. Besides, don't say that people are pretending to be crazy, even if they are pretending to be dead, they can do it, not to mention that she is just pretending to be a patient with degraded intelligence? went to see Qin Qin today, and when Tan Zhi picked up the doll on the ground, he had more of his own reasoning about Qin Qin.

"Aze, didn't you ask me why I laughed today?" Tan Zhi glanced at Aze, and a charming smile rose at the corner of his mouth: "Because I discovered Qin Qin's secret." ”

"Secret? What secrets can Qin Qin have? She was nothing more than an intellectually degraded patient. "Aze has always believed that Qin Qin cannot be the murderer. He has always thought that Qin Qin is the worst one in the whole case. After all, her life now is not as good as that of death.

"Are you really sure she's a patient and not a pretending to be sick? This doll was given to her the last time we visited Qin Qin, and she threw it on the ground, looking like she hated it. ”
