The moonlight tonight was extremely beautiful, and Sisi was lying on the bed in the dormitory alone, tossing and turning and unable to sleep.

A strange itch began to slowly spread to Sisi's whole body, and after a while, this itching invaded her entire body unscrupulously, Sisi couldn't help but scratch it non-stop, and she didn't even notice that there were blood marks on her body.

It's just that such crazy scratching can't alleviate the pain of Sisi's itching in the slightest, but makes her feel more and more unbearable.

So, Sisi, who couldn't bear it anymore, got out of bed and prepared to go to the toilet to take a shower.

The cold water hit Sisi's body, but the itching on her body was still unrelieved, and a small utility knife in the corner of the toilet suddenly emitted a bright light, and a melodious and ethereal singing voice came......

Sisi, who was in the shower, suddenly laughed as if she was relieved: "Here, I knew it would come!" ”

……

A strong smell of blood woke Xiao Yao from her sleep, and Xiao Yao held her breath and listened quietly.

There was an even sound of breathing in the dormitory, a faint yellow light came out of the closed door of the toilet, and an extremely strong smell of blood drilled straight into Xiao Yao's nose.

Xiao Yao reluctantly got out of bed and walked towards the toilet, just a light push, and the door of the toilet opened, however......

"Ahh A scream pierced the quiet night.

……

A rapid siren pierced the silent night sky of S City, and the sirens sounded from far to near, hurrying towards A.

The five girls in the 404 dormitory in Building 2 sat in the dormitory hall with pale faces, their hands shaking uncontrollably with their hands holding the warm boiled water.

In order not to cause panic, the police car turned off the sirens when it drove into the school gate and quietly parked outside the two dormitory buildings.

A middle-aged police officer in a black police uniform walked up to the five girls.

"Which of you called the police, what's wrong?"

His voice was calm and steady, as if it could suppress anyone's restlessness.

"It's me." Xiao Yao raised her head, "It's Sisi, something happened to her." ”

Before she finished speaking, Xiao Yao seemed to have thought of some terrifying picture, and her face suddenly turned pale.

"What's wrong?"

"She, she's dead......" After saying this, Xiao Yao sobbed helplessly.

"Dead? How did he die? ”

"I don't know, I don't know how I died."

"Take us to the scene of the crime."

The police officer and his assistant followed the five girls in the dormitory and walked slowly towards dormitory 404.

As soon as I arrived at the entrance on the 4th floor, there was a faint smell of blood in the air, and the closer you got to 404, the stronger the smell of blood became.

As soon as they arrived at the door of the dormitory, the five girls did not want to take another step into the dormitory, but pointed to the open toilet door and signaled that the body was in the toilet.

The police officer was a little dissatisfied with the attitude of the girls, and frowned slightly, but he still did not hesitate to walk to the toilet with the assistant next to him.

I saw that the victim was lying in the bathtub at this time, but this seemingly peaceful picture was particularly bloody due to the tragic scene.

The victim's skin was covered with intricate scars shaped like cherry blossoms of various sizes, and she was now soaking in a bathtub of blood due to more blood loss.

Her face was contorted to an unimaginable degree of extreme fear, her white pupils were bloodshot, but the strangest thing was the suspicious curvature of the corners of her mouth, which seemed to be a relieved smile.

The middle-aged police officer looked at the tragic scene in front of him, a thick haze stretched on his tightly knit brow, he lowered his head and whispered a few words to the assistant beside him, and then blocked the scene with the assistance of the assistant.

Half an hour later, the middle-aged police officer added some warm water to the remaining five girls in dormitory 404, and then took out a notebook and began to take notes for them.

"May I ask who of you was the first to discover the dead?"

"It's me." Xiao Yao replied.

"When and under what circumstances were the deceased found?"

"Around 2:00, I woke up with the smell of blood, and then I went to the toilet and saw Sisi who had been killed."

"Has the deceased behaved in any recent ways?"

"Like...... No. ”

The middle-aged police officer asked a few more questions, then left a business card, and took his assistant back to the police station.

The school received the information as soon as the accident occurred, but the school asked the 404 girls to keep it confidential for the reason that they could not affect the learning of others, and they must not disclose the news of Sisi's accident.

404 The remaining five girls left the principal's office, and because of the double blow of sleepiness and nervousness and fear that they couldn't help staying up all night, they fell asleep in their beds.

Xiao Yao's mind was extremely clear, she looked at the empty bed under her, but her thoughts returned to the last question asked by Officer Huang: What unusual behavior did the deceased have recently.

If, then......

Xiao Yao's thoughts went back to a week ago, when she was in class that day, she received a small note written by Sisi, asking her to eat well and go to the back garden of the school, and she had something important to ask Xiao Yao to help with.

Because she was worried that something would happen, Xiao Yao went to the appointment without eating dinner that day, but at that time, Sisi just took out a thick black notebook, and did everything possible to explain that Xiao Yao must not open it until a week later.

Xiao Yao wanted to ask something, but Sisi didn't say anything, just smiled mysteriously, and then gradually walked to the back garden in the afternoon sun.

At that time, the breeze brought a slight whisper: "Xiaoyao, now only you can help me." ”

The soft voice was fleeting, and at that time, Xiao Haruka even suspected that she was having auditory hallucinations, and at the same time, she was in a hurry to go back to the dormitory to prepare for the English Level 4 exam, so she forgot about it.

Today, Sisi suddenly had an accident, and this incident returned to Xiaoyao's death memory.

Wait a minute! Notebook? Notebook!!!

Xiao Yao got up from the bed and began to find the notebook as she rummaged through the cabinets.

……

A melodious mobile phone ringtone came from Xiao Yao's handbag, a string of unfamiliar numbers flashed on the mobile phone screen, Xiao Yao hesitantly pressed the call button, "Hey! Who are you looking for? ”

"Hello, are you Qin Xiaoyao's classmate?"

"Yes, I am, you are?"

"Hello senior sister, I'm Shen Yan."

"Shen Yan? Could it be the legendary star senior Shen Yan in the senior year of forensic medicine? Hearing the name Shen Yan, Xiao Yao's pupils trembled slightly.

Xiao Yao thinks that she is not a girl who only thinks about falling in love during college, and she will not deliberately inquire about any alumni in the school, but the name Shen Yan is the most popular name among all the girls in University A.
