No such person [criminal investigation]

Jinning City, on the side of the road outside the West Railway Station.

The young man who was noted by the little girl as "Teacher Jing Wangyun" stood at the intersection, checking something with his mobile phone, while waiting for an online car-hailing car.

He was dressed in black, with a peaked cap, in-ear headphones, and a simple gray backpack. He looked a bit cold with a deadpan expression on his face.

A man has been standing behind him for a while. He has passed by him many times, but he doesn't look up when he sees him. He is probably obsessed with Weibo or small videos, and he can't see himself at all.

Looking to the left and right, there happened to be a group of more than a dozen people walking this way, and the leader was holding a small red flag, which seemed to be a tourist group visiting Jinning.

While they were passing the young man, this man sneaked into the team, pretending to inadvertently squeeze the young man, then brushed past him, and took the wallet in his pocket.

But in the next moment, his hands were grabbed by a strong force, and there was a sharp pain in his shoulders and leg sockets one after another, and he immediately knelt on the ground.

In a panic, he looked back, and saw the young man looking down at him coldly.

——Could it be that he had discovered him a long time ago? !

This thief is a big and three thick man, with a lot of strength, and his tendons are by no means vain.He himself didn't expect that he would be easily subdued like this by a man who looked so weak.

At this moment, Jing Wangyun's expression was cold and his eyes were dark. It was hard to imagine that he was the same person who gently touched the little girl's head a few days ago and said to her, "Be obedient and listen to the new teacher."

Soon, the online car-hailing service arrived.Jing Wangyun simply took the wallet away from the thief, pushed him away without saying a word, then got into the car and drove away.

He went to Seventh Junior High School.

Walking along the road full of phoenix trees on both sides, turning into an alley and walking a few steps, he found that the snack bar he used to frequent was still there.

It's not time for dinner, there are not many guests.

After Jing Wangyun walked in and sat down, the proprietress quickly came over to greet him.

With some exclamation in her tone, she said, "Hey, isn't this Wangyun? You haven't seen this... for more than ten years, right?"

Jing Wangyun smiled. "There are so many guests, it's hard for you to remember me."

"I remember, why don't I remember. I said before that Wang Yunchang is so good-looking, I can't guarantee that he will become a big star in the future. At that time, I will say that this big star has been eating at my place since he was a child!" The proprietress was quite Excitedly chatted with him for a while, and asked him, "Do you still want the third one?"

"Yes. A serving of stewed beef mixed with noodles, a bowl of beef bone soup, and a piece of sticky pancakes made by yourself."

At the same time, the Binhu community on the outskirts of the city is tens of kilometers away.

In the off-road vehicle, Qi Zang ate with his head down in the driver's seat, and Xu Ci peeled apples in the passenger seat.

Holding a small knife, Xu Ci quickly turned the apple with one hand, and cut the knife with precision and ruthlessness with the other. Not only was the apple skin unbroken, it was also as thin as a cicada's wing.His demeanor was focused yet a little cold.Much like when he was dissecting a chicken with a kitchen knife.

In less than a minute, Xu Ci finished peeling the apple.

Qi Zang, who raised his eyes to see this scene, felt his heart warm.

"I'm so moved that I don't know what to do" before he said the sentence "bring me the food and peel the fruit with my own hands", when Qi Zang saw Xu Ci take a bite of the apple.

Qi Zang: "..."

Xu Ci noticed something and looked back at him. "Huh? Have something to say to me?"

Qi Zang shook his head. "No. Thank you for bringing me the meal."

"You're welcome. It's still too hard for you to handle the case." Xu Ci said lightly.

At this time, Qi Zang's cell phone rang, and it was his mother calling.

"Mom? What's wrong?"

"Don't you keep talking about that classmate named Xu Ci? You often lose your mind when you mention him."

Qi Zang was taken aback for a moment, then coughed lightly, glanced sideways at Xu Ci's expression, and said, "Cough, what's wrong?"

Then I heard my mother say: "I took your aunt to the high-speed rail station today, and saw a person who looked a bit like him."

Putting it aside, Qi Zang will immediately ask for details.

Not now.After all, people are by his side.

Qi Zang said, "Did you read it wrong?"

The mother's voice was very puzzled: "No way? I have had dinner with him a few times, and I also met him in your dormitory. He is so beautiful, I remember it clearly! Although it is true that it is just a glimpse... But it feels very similar .Hey, why are you reacting so calmly?"

"I found out about him, and he's abroad. You must have read it wrong. I'm handling the case here, hang up first."

After chatting with his mother a few more words, Qi Zang hung up the phone.

Xu Ci, who was next to him, was eating an apple while looking at the random murder scene photos sent to him by Qi Zang with a calm demeanor. "Compared to the wound, the blood flow is actually very little. Except for the fatal wound of the knife, the rest of the knife should be repaired after death, right?"

"Yes. People are dead, and they cut so many knives, it seems to be revenge." Qi Zang said, "Where is the specific fatal injury, we will have to wait for Gong Nianci's autopsy to determine."

"Yeah." Xu Ci asked again, "How are you chatting with that Yuan Eryang? Does he know about the utility room next to the bedroom?"

Qi Zang said: "Yuan Eryang didn't know about it at all. He said that this house was bought by Xia Rong herself. It was bought before marriage and handed over after marriage. She hired someone to do the decoration, and he didn't participate in it. They are all married, so she naturally doesn't have to live in it. He thinks this place is remote, the surrounding facilities are not perfect, and the rooms are small, so he doesn't like to live there."

At first Li Zhengzheng didn't ask anything from Yuan Eryang, he just thought it was a very loving couple.Qi Zang's eyes were so vicious, and he asked something from Yuan Eryang in a few words. It turned out that their husband and wife were not as happy as the outside world thought.

According to Yuan Eryang, they have a good relationship, Xia Rong treats him very well and relies on him very much.Their conflicts mainly come from the family——

Their family didn't think much of Yuan Eryang. Although she played the piano, she seemed to be better than those actors, but after all, she had to show her face.In Yuan Eryang's mother's opinion, how can there be so many people who really know how to appreciate the piano?Those who are willing to buy tickets to watch her play the piano are all men who go for her face.To put it bluntly, she was selling her hue.

In addition, Yuan Eryang's mother also thought that an artist like Xia Rong was too noble, and she never knew how to socialize with other wives in the circle, and participated in activities such as cake making and flower arrangement, which made many wives complain in their stomachs, saying that Yuan Eryang had taken A daughter-in-law with a lofty heart looks down on their housewives.

Under such circumstances, it is no longer easy for Xia Rong to continue on the road of playing the piano. It is self-evident what kind of eyes and words will run into her when practicing piano at home.

Every time Xia Rong had conflicts with her mother, she would go back to this house in the suburbs to live alone, and then Yuan Eryang would go over and coax her.

Yuan Eryang always thought she had a bad eye, and said that she must have been fooled by the developer's words that this is a key construction area of ​​the Jinning City Government. The surrounding area is desolate and there are no other communities. As for supporting facilities, it doesn't matter if there are no nearby hospitals and schools. Yes, there is no large supermarket yet, only a small community store. If you want to buy vegetables, there is only a small private store to buy, and the meat in it is not too fresh.

Xia Rong likes to live here, saying that it is quiet here.

Desolate, few people, low occupancy rate, she likes it.

The first few years of marriage were the days when Xia Rong had the most conflicts with Yuan's mother, and she often ran to this side, only to be coaxed home by Yuan Eryang.Later, she came less frequently.Especially after giving birth, she didn't come to live with her for almost a whole year.

Until this time, in order to prepare for her comeback performance, she came back here to practice piano day and night half a year ago. Apart from wanting to have a perfect performance when she returns to the performance stage, it is probably also to relieve some depressed emotions.

Yuan Eryang also said that the relationship between the two was really very good. When his mother disagreed with him marrying Xia Rong, he even knelt down to his mother.

The two sounded like a story about Cinderella and the Prince.

Sighing, Yuan Eryang said: "We were really in love at the beginning. It's just that there are always conflicts in life, which consume some feelings... But the child has also become the bond between us, and I cherish her as a wife very much. I don't know why she would..."

·

When Qi Zang said this, he added. "Yuan Eryang said that Xia Rong's decoration is also the kind of shopkeeper who throws her hands away. She asked on Weibo if there was any reliable decoration company recommended. One of her loyal fans recommended one, and she used it, and there was no one after that. Watch for yourself.

"I will start with this fan in the future, and investigate him and the people in the decoration company. I am not sure whether Xia Rong knows about the utility room, but in short, it is possible to install a single-sided glass in the room and know how to hide the partition." The existence of space...the person who decorated it is very suspected. From this perspective, this case should not be difficult."

Hearing this, Xu Ci scrolled through the phone's photo album and found the photos of the bedroom.

He enlarged the part of the dressing table and looked carefully at the mirror. When he was concentrating, he didn't realize that he tilted his head slightly, as if he could see what was hidden behind the mirror through a photo.

Qi Zang was somewhat amused by his actions, and asked, "What did you think of?"

Xu Ci put down his phone and looked at Qi Zang: "Have they done this in the master bedroom here?"

Hearing this, Qi Zang was almost taken aback.

Every time such words were mentioned, Xu Ci reacted calmly, after all, he didn't even change his face when he told Shu Yan that he had slept with Qi Zang.

Qi Zang felt a little uncomfortable, rubbed his nose and said: "It seems that you have been with me. I asked him, and he said that he had done so many times. But he seldom stayed here overnight. Just go."

The reason why the two paid attention to this issue was nothing more than thinking about the motive of the murderer.

Combining the situation at the scene and the corpse, there is a possibility that the murderer usually hides in a secret space and peeps at Rong Xia in the master bedroom.

If you only get psychological satisfaction through peeping, you can only attribute this person to being wretched, disgusting, and bad in character, which is contemptible.

But this person has obviously lived in the secret space for a long time, seems to be dormant here, only staring at Xia Rong, which makes this person seem a little sick, probably has some kind of almost paranoid love for Xia Rong .

Originally, he only stared at Xia Rong for a long time, and regarded her as a fairy who only dared to "peep" and was not to be approached and played with. This is possible.

When Xia Rong's husband came one day, he saw them having sex with each other through a one-way mirror, and the more he thought about it, the angrier he became, thinking that she had been defiled, so it was very possible that he went to rape and kill her of.

In this case, it's passion killing.

But if Yuan Eryang and Xia Rong have had sex in the master bedroom many times, the murderer's murderous intentions will not be based on this.

Hearing Qi Zang's answer, Xu Ci frowned and asked him, "Didn't Yuan Eryang come here last night?"

Qi Zang shook his head: "No, not only last night, he didn't come for the last two days. According to Yuan Eryang, Xia Rong would go home three or four days a week before, after all, she had to accompany her children. But now the performance time is coming soon, she The intensity of the practice has been strengthened, and I usually don’t let anyone disturb me.”

"That's a bit strange..." Xu Ci said, "If you rule out this motive, you can only think about Xia Rong discovering the compartment and finding the murderer, who panicked and killed her. But..."

Qi Zang took his words: "But judging from the preliminary survey results, the traces at the crime scene do not support this."

According to Xu Ci's point of view, Xia Rong's first reaction should be to escape from the house immediately and call the police, which is in line with common sense.

However, after preliminary investigation, the murder weapon was a kitchen knife, which was usually placed in the kitchen.The door and the kitchen of Rong Xia's house are located in two directions.

If the murderer wants to kill her, he should immediately catch up and stop her from opening the door to escape. It is possible to accidentally smother her to death during this period.But without any tying up of her, the possibility of taking her back to the living room and going to the kitchen to kill her with the kitchen knife is relatively small.

After all, Rong Xia is a living person, she can run.Furthermore, if so, at what stage did the violation occur?No matter how you think about it, it's a little unreasonable.

And if Xia Rong had rushed to the door at that time, the possibility of the murderer going to the kitchen to get a knife and chasing after him was relatively small.Firstly, Xia Rong would not run so slowly; secondly, the reason for the murderer to do so is really not sufficient; finally, there are no traces of fighting at the door, the entrance, etc., temporarily excluding the case that the blood has been cleaned up. No trace of blood.

If the murderer is the person who has been spying on Xia Rong in the secret space.

What his motives are, is still unknown.

After thinking for a moment, Xu Ci raised his phone and returned to the picture of the crime scene. He zoomed in on what he saw, but he still couldn't see it clearly.He asked Qi Zang: "What is this?"

Qi Zang said: "A sheet of music."

"Music score? If she was going to the piano with the score to practice, why did she play the music? Besides... the performance is about to happen. At this time, she will not practice new pieces, but will only practice the pieces to be performed repeatedly. But these She should already know the tune by heart, do you still need the score?"

Xu Ci frowned and said, "It's not unusual for this score to appear here."

"Let the music score first let the fingerprints be extracted, and the physical evidence be photographed. I'll show you when it's done in a while." Qi Zang said.

"Yeah. By the way, show me the music Yuan Eryang heard, and the related audio. Well... you can just give me the deceased's computer."

At this point, Xu Ci seemed to think of something, his voice stopped abruptly, and then he turned his head to look at him, and asked belatedly, "Why am I always helping you solve cases?"

Qi Zang looked at him sincerely: "Mr. Xu sacrificed his weekends to help us. On behalf of the third criminal investigation team, I would like to express my sincere thanks to you."

Xu Ci: "..."

Suddenly, three sounds of "clang, clang, clang" came from the glass on the side of the driver's seat.

Qi Zang rolled down the car window and saw Li Zhengzheng.

"Boss, we copied the surveillance video outside this room. Would you like to take a look?"

After Li Zhengzheng finished speaking, he was stunned when he saw the "girl" in the passenger seat. "Who is this……"

Qi Zang coughed lightly. "Hey, he's my girlfriend, your sister-in-law, who came to deliver food to me. His name is..."

Considering that Xu Ci's appearance today is very different from that day, Qi Zang temporarily made up a name: "It's called Zhang Xiaoyu."

Xu Ci: "...?"

——"Cloud" will become "rain" and fall?What kind of brain circuit is Qi Zang?

In another situation, Li Zhengzheng is obviously the kind of person who has no EQ and no vision, and asked in front of "Zhang Xiaoyu": "Isn't your girlfriend a tough rich woman? Are you cheating or changing so quickly?" Are you married? Haven’t you never been in a relationship before, please pass on your good fortune to me. You have bloomed a thousand-year-old iron tree recently.”

Qi Zang: "..."

Xu Ci: "..."

Li Zhengzheng came to his senses immediately, and smiled "hehe" at Xu Ci. "Sister-in-law, I'm joking, don't take it to heart!"

Xu Ci: "..."

Afterwards, Xu Ci got out of the car, leaned against the car door and slowly ate an apple.Qi Zang also finished his meal, and followed Li Zhengzheng back to the fourth floor to watch the surveillance.

The surveillance camera was hung at the door of the room, but there was no one in the room.

After reading the SD card, the monitoring showed that no one had entered or left Room 403 of Xia Rong's residence until Yuan Eryang entered the door this morning.

The murderer could only leave through the window.The fourth floor is not too high, so it is completely feasible to do so.

Qi Zang quickly went to the balcony to look down.The floor height here is not high, and the air-conditioning racks are arranged neatly and relatively densely, so it is entirely possible to climb to the ground along here.

Qi Zang quickly called for trace inspection. "Help carefully check and extract the footprints and fingerprints on the balcony and the air-conditioning rack."

It is also possible for the murderer to use a rope for safety.Through a special tethering method, it is possible to tie the rope to the current floor first, wait for someone to go down to the air-conditioning rack on the next floor, and then untie the rope on the previous floor and tie it to this floor again, and so on.

So Qi Zang added: "Check the wear marks on the railing to see if there are any new ones. In addition, collect footprints from the ground directly facing the balcony to see if you can deduce which direction the murderer fled to!"

As soon as the words fell, Qi Zang himself rushed down the first floor with Li Zhengzheng.The place is desolate, and there is much wasteland around it, and the dust on the ground is heavy.Therefore, it can be clearly seen that there are indeed relatively dense footprints in the place facing the balcony of 403, and it can be vaguely seen that the footprints seem to be heading north, but the specifics need to be further judged by professional means of trace inspection.

Following the technical investigation, he went to the property for monitoring, and Qi Zang asked the security guards some more matters, and then walked towards his off-road vehicle with the sheet music in his gloves.

When Qi Zang went, it happened that Shan Kang was chatting with Xu Ci there.

Probably because Shankang couldn't find Qi Zang, he wanted to go to his car to have a look, but he saw Xu Ci leaning against the side of the car.

The two of them didn't know what they were talking about, but the atmosphere looked pretty good.The breeze caressed Xu Ci's long hair, and he smiled faintly, with gentle brows and eyes.Shan Kang also smiled, his face was still red.

Qi Zang frowned immediately.Coincidentally, after such a short time, two men walked up to Xu Ci one after another, and they both took out their mobile phones, probably wanting to add Xu Ci's WeChat.

Qi Zang's mentality is that fortunately there are not many residents in this community, otherwise I don't know how many people want to pry into his corner.

With a light cough, Qi Zang walked over with a serious face.

When Shan Kang saw him, he hurriedly said hello.

Qi Zang raised his eyebrows coldly. "What are you doing?"

"Come down and get some water. Go to work right away!" Shan Kang said.

"Oh." Qi Zang raised the music score in his hand, "Your sister-in-law's name is Zhang Xiaoyu, she knows the piano, I'll ask him to see if he can see the way."

Shan Kang seemed very surprised when he heard this, he glanced back and forth between Qi Zang and Xu Ci's faces, and hurried away blushing.

Qi Zang shook his head at his back, then looked at Xu Ci. "Think of you as a beautiful and ruthless young lady. If he knew that it was your fault that he lost Zhu Xiu last time, he wouldn't know how he felt. After that incident, he regretted and felt guilty for a long time."

Xu Ci was expressionless: "Oh. I will find an opportunity to apologize to him in the future."

Qi Zang couldn't put on a serious face anymore.Xu Ci didn't seem to have said anything, but he was immediately amused, then he raised his head to the car and took Xu Ci back into the car.

Taking out a pair of gloves for Xu Ci to put on, Qi Zang handed him the music book.

The book was stained with a lot of blood, and the music score in some places is not clear.

Xu Ci turned over page by page, and finally stopped at the page with the most blood.

This page has the most blood, which means that when the murder happened, the book was spread out on this page.

Xu Ci handed it to Qi Zang. "When you arrived at the scene, was this page the book?"

Qi Zang shook his head, and then looked at the content of this page, but couldn't understand it. "What's the doorway here?"

"The trend of things is more and more in line with my speculation just now. The appearance of this music score is very unusual. This is a very basic music score book, which can be regarded as an introduction for those who play the piano. Xia Rong is not very famous, but she is qualified. Holding a solo recital should be regarded as a great master in the piano world. What does she do with the most basic music book?"

Xu Ci pointed Qi Zang to the content on the page. "Look, the page with the most blood is twelve equal temperaments, which is the most basic knowledge of music theory."

Qi Zang asked: "What is the law of twelve equals?"

"To put it simply... the ancient Chinese temperament system was formulated through the three-point profit and loss method, which can set the five musical scales of Gongshangjiao Zhengyu. The West uses the five-degree mutual generation law. These two methods have corresponding defects, such as inconvenient transposition. I don’t know much about the specific application…”

Xu Ci explained, "But after all, there was the twelve equal law, which averaged an octave into twelve equal divisions according to the ratio of the wavelength of the sound wave. In fact, it was calculated by mathematical methods. By the way—— "

Xu Ci put down the music score, picked up his mobile phone and showed it to Qi Zang. "I just checked Xia Rong's Weibo for a while, and found out that she has a very fanatical fan. The decoration company was also recommended by him."
