June 16 at 11:36 p.m., Saturday ** City

Tonight was not a good day, coinciding with the rainy season, and from the evening onwards the whole city has been intermittently drizzling, after the rain gradually intensified, and the raindrops fell into a line, enveloping the city in a curtain of water. There was a heavy humidity in the air, and when the wind blew, it made people feel very cold. The weather station says that the temperature at night may drop to about 18 to 20 degrees, which is called "cold water yellow plum".

Tang Jing sat alone in front of the computer desk in the bedroom, her eyes staring intently at the screen, her expression was focused, her two hands were tapping on the keyboard quickly, and she also moved the mouse from time to time, so busy that she didn't even bother to take a sip of the hot cocoa placed next to the case. The half-peeled apple and fruit knife were placed on the plate, the skin of the apple was already yellowed, and today was the weekend, and her parents were out to party with friends, leaving her alone at home to surf the Internet.

Tang Jing came into contact with the Internet two years ago, when she had just finished the high school entrance examination, and it was her free time. Her friend taught her how to surf the Internet, and she was almost immediately captivated by the novelty, giving herself the screen name "Blues Nimbus". The illusory world of Wushu's head is so beautiful, Tang Jing feels unrestrained and unusually free there, and there are endless topics to talk about with netizens who have never met, and there is endless fun.

Since then, surfing the Internet has become an indispensable part of Tang Jing's life, especially after the family purchased a computer, her desire to surf the Internet has been out of control, almost to the point of forgetting to sleep and eat and staying at home.

Today, she sat in front of the computer as soon as she woke up in the morning, spent the whole day online, and after making a bowl of instant noodles in the evening, she returned to her bedroom, and sat until half past eleven.

At this time, the rain outside the house was getting heavier and heavier, and it was constantly knocking on the window pane, making a dull "knock" sound. Tang Jing felt very annoyed, and it was pitch black outside, which was also a little terrifying. So she took advantage of the time to chat with her friends on QQ, bent her aching fingers, turned up the sound of the stereo, and chose a few faster songs in WINAMP. The sound of the music soon overshadowed the raindrops, and the atmosphere in the whole bedroom suddenly became lighter.

Tang Jing exhaled with satisfaction, rubbed her somewhat reddened eyes, picked up the cup and took a sip of hot cocoa, and immediately returned her attention to the Internet. Her fingers tapped lightly on the keyboard. In the past two years on the Internet, Tang Jing's fingering practice has been perfect, and now she can chat with more than 20 people at the same time without confusion.

I don't know when Tang Jing felt that something was wrong. Her friends on QQ began to complain that her reply was too slow or that she couldn't receive her words at all, and she replied quickly after receiving the message.

"QQ is hungry again."

Tang Jing frowned slightly.

QQ is the most popular chat software in China, and when the QQ server responsible for handling information transfer is too busy, the information sent by individual users will occasionally be lost. Today is the weekend, and the number of people on the line is astronomical, so small accidents like this happen from time to time. Tang Jing used to call this kind of accident "QQ is hungry" and "QQ is eating".

But this is the first time she has seen such a continuous eating and talking like today. This conversation can't go on at all, and soon the friends on the list stopped chatting, the avatars stopped jumping, and the whole QQ became silent, only to see a row of offline avatars motionless, and each avatar turned gray.

Tang Jing pursed her lips, thinking that this server is really annoying, a rare weekend, and she is talking about it. But she had no choice but to hang QQ, listening to music while boredly browsing the forums she often attended.

After about five minutes, the music suddenly stopped, and there was a sharp electronic whistling sound from the speakers, and the room fell silent for a moment.

Her first reaction was that the computer had crashed, but before she could start it up, there was a "beep" sound from the speaker that had just fallen silent. This is a QQ-specific sound that means "someone sent you a message". Tang Jing is very familiar with this,

So without thinking, she pressed the hotkey CTRL +Z to extract the information, and then she snapped, because she had never seen this avatar in her friends list. The avatar was blurry, faintly red in the lead ash, and blank where the name and QQ number should have been displayed.

Let's hit the road

Looking at the information box on the screen, Tang Jing felt a chill on her back for no reason, and at the same time, a cold rose from the tail vertebrae, crawling up her back to the top of her head, and a layer of cold sweat began to appear on her forehead.

"It's just an illusion, it's an illusion."

Tang Jing struggled to convince herself while reaching for the keyboard.

(200-06-17 00:00:07)

Who are you?

There was no answer

The cup next to the case suddenly trembled, and the cocoa in the cup shook in circles, and the outside of the house was still stormy. Suddenly, the optical drive popped out automatically with a "boom", and a low "beep" sound came out of the speaker, and the other party finally replied, Tang Jing hurriedly turned her head to look, and in the next moment, her pupils shrank rapidly......

June 17 at 8:15 a.m., Sunday S City

The water on the side of the road reflected the white clouds drifting in the sky, and the rainy season that had lasted all night yesterday finally stopped. The air is fresh and pleasant after the rain, and the whole city of S looks particularly quiet under the early morning sun.

Xiao Nuo walked on the street with a pale blue umbrella on his shoulder, humming Stefanie Sun's "Moonlight" in his mouth, and from time to time deliberately stepped into the stagnant water and stomped his feet hard, splashing pieces of water. Whenever she puts on her rain boots, she always likes to walk like this. It's a habit she's been cultivating since elementary school, and it's still the case until she's a freshman year of college.

Pedestrians looked at her inexplicably, but she herself was happy to do it.

Today she is going to work as a tutor in her aunt's house. Her cousin Tang Jing is a sophomore in high school this year and will face the college entrance examination next year, so her cousin, who was admitted to the city's foreign language college with high scores, is naturally duty-bound. So every Sunday, Xiaonuo would go to Tang Jing's house and give her two hours of English and math tutoring.

Xiao Nuo and Tang Jing have played since childhood, the two are like sisters, they have nothing to say, and Tang Jing's mother likes Xiao Nuo very much, so this tutor is also very easy to do, and there is no pressure. It's not so much family tutoring as two girls getting together to study.

Today is the third tutoring, so Xiaonuo got up early, and left the house after eating early. She didn't prepare for classes, and for her, teaching English at the high school level was easier than skipping classes in college. It happened that the rain had just stopped in the early morning, and the air was refreshing, so she simply didn't even ride a bicycle, put on rain boots and walked all the way to Tang Jing's house.

Walking downstairs to Tang Jing's house, Xiao Nuo stopped, she felt that the atmosphere was a little strange, as if something had happened. She looked left and right, didn't notice anything strange, shrugged, and pressed the button on the elevator.

The dilapidated old elevator is a cultural relic unearthed in which year BC, and it is very noisy, swaying leisurely while moving, and the cable makes a "squeak" sound, which makes people feel no sense of security at all.

Xiaonuo stood in the elevator and suddenly shivered for no reason.

Tang Jing's family lives in 702 on the seventh floor, and the old elevator walked for nearly a minute before it arrived. As soon as the iron door opened, Xiao Nuo quickly jumped out of the elevator and stuck out his tongue.

When she came to the door of Tang Jing's house, she was about to reach out and knock on the door, when she suddenly found that the door was hidden. Xiao Nuo shook the door open, put his head in while taking off his rain boots, and said:

"Auntie? Uncle? Tang Jing? ”

No one answered, only a cry was heard coming from inside the house. Xiao Nuo heard that it was her aunt's voice, and she was shocked, so she quickly took off her boots and ran into the living room in three steps and two steps.

In the living room, Xiao Nuo first saw his pale-faced uncle standing on the edge of the windowsill, holding the phone in one hand and twisting the burning cigarette butt in the other; The aunt knelt beside the sofa, holding her head with her hands and crying, her shoulders trembling violently. Lying motionless on the sofa was none other than Tang Jing!

“…… This...... This...... What's going on? ”

Xiao Nuo was shocked and couldn't speak, and froze in place, even forgetting to put the umbrella in the umbrella tube.

"Xiao Jing...... Something happened to her. ”

My uncle turned his face from the windowsill, his voice low and hoarse, and the face of a man in his thirties suddenly became much older.

With a "bang", the umbrella in Xiaonuo's hand fell on the floor, his face changed greatly, and he hurried to the sofa. I saw Tang Jing lying motionless on the sofa, her eyes closed, her expression distorted, her face pale and terrifying, she seemed to have suffered great fear before she died, and she couldn't feel the breath of life in her whole body at all.

"Tang Jing!!"

Xiao Nuo held her right hand, and found that it was cold and stiff, without the usual soft touch. When she looked closer, she found a long, narrow and deep wound on her right wrist, with neat edges, as if it had been cut by a sharp blade; A streak of blood snaked down from the wound.

"Yesterday, I went out with your aunt to socialize, because it was very late, so I called home to tell him, but no one answered, we thought Xiao Jing had already gone to bed. We only got home this morning 10 minutes ago. As soon as we got home, we saw Xiao Jing lying in front of the computer desk, holding a knife in her left hand, and her right wrist was cut open, bleeding a lot............"

When the uncle said this, he couldn't stop talking, and the aunt's cry became louder again.

"So, then call an ambulance?!"

"We just called 110 and they arrived right away...... But it's too late......"

Xiao Nuo's tears burst out of her eyes, she slowly put down Tang Jing's hand, and turned her head to look at the bedroom. It was supposed to be time for the two of them to sit there talking, laughing, and studying, but one of them had disappeared forever without the slightest warning.

The bedroom door was wide open, and Arnold stood up, wiped her tears, and walked inside. She didn't know what she wanted to do, she probably just wanted to take another look at her life and feel her breath.

As soon as he entered the house, Arnold smelled a faint smell of blood. She took a deep breath and walked over to the computer desk.

The computer screen is pitch black, the desktop and most of the keyboard below are dyed red, and there are blood-red fingerprints clearly on several keys, and the same blood stains are also on the mouse, which is shocking; As can be seen from the direction of the blood stains, the blood flows from the wrist into the keyboard, then flows down the gap between the keyboards to the desktop, and then drip to the floor, forming a large pool of blood under the chair. A fruit knife was placed next to it, and there was blood on the blade. It was evident that Tang Jing slit his wrists—or were cut by someone else—and then lay down on the keyboard, and finally died in such a position.

Suddenly, Xiaonuo heard a low whining sound, she looked left and right, and found that it was the noise made by the fan in the case, and the indicator light of the case was still on. Xiao Nuo's heart moved, carefully stretched out his hand to the mouse, and gently pushed it, but the blood stains had already coagulated and would not touch his hands. With the movement of the mouse, the 29-inch monitor lit up with a "snap", and the WINDOWS interface appeared on the screen, and the wallpaper was a group photo of the four handsome guys F4 with bright smiles.

Tang Jing's computer system has a waiting time of 10 minutes, which means that if there is no operation within 10 minutes, the machine will automatically start and turn off the monitor to save resources. But the whole system is still working, and the screen can be restored with just a single mouse movement. Tang Jing's parents didn't understand computers, and when they saw that the screen was black, they thought it had been turned off, and they couldn't think about anything else when their daughter died suddenly, so the system has been running in an energy-saving state until now.

Suddenly, Xiao Nuo thought that there were still blood-colored fingerprints left on the keyboard and mouse, which showed that during the period of time when Tang Jing had blood flowing into the keyboard after cutting her wrists, she or others had operated the computer with a blood-soaked keyboard and mouse, so the blood-red fingerprints were left.

"What is it for to be operating a computer when you are about to die?"

Xiao Nuo felt that whether this fingerprint was Tang Jing's or not, this move must have extraordinary significance.

Yesterday, she also discussed with Tang Jing on the phone about traveling to Huangshan during the summer vacation, and she didn't see any signs of suicide at all, so she didn't believe that Tang Jing committed suicide at all.

So she looked up at the screen, if no one had touched the computer since Tang Jing's death, then the system should now maintain the traces of the user's last operation.

The icons of the two small computers in the lower right corner of the screen are lit up, indicating that they are still online; Internet ants continue to download MP3s; The windows of the three Internet Explorers are minimized in the following task bar, and the content is the Sina homepage, the banyan tree literature station and a mobile phone ringtone station; The QQ dialog hangs in the middle of the screen, showing the last message from someone else in QQ. The avatar was blurry, faintly red in lead ash, and blank where the name should have been:

（200-06-17 00：01：20）

Let's hit the road

When Xiao Nuo saw this information, a chill rose in his heart, and he couldn't help but shiver when he thought of the blood-stained keyboard beside him.

This is sent by someone on QQ, and it is the last message, so he or she must have had a conversation with Tang Jing before. Arnold cautiously pushed the mouse and moved the arrow to the "Chat History" option, wanting to check the previous records.

She was about to click when she heard a chaotic stream of footsteps and shouts outside the house, and the 110s had arrived. Xiaonuo usually likes to read mystery novels and comics, and knows that the murder scene should be kept in the state it was in when the crime occurred, so she quickly let go of the mouse and walked out of the house.

The officers came to the bedroom and began to carry out the survey work in an orderly manner; A police officer questioned his uncle with a notebook and a pen in his hand, a forensic doctor conducted a preliminary examination of Tang Jing's body, and Xiaonuo kept comforting her by her aunt's side, and for a time the room was crowded with people. When the neighbors heard the news, they were all looking in the window or in the door, whispering in this direction.
