Time passes. In the blink of an eye, it was time for the end of school. Even during the holidays, the senior high school students have to study in class until seven o'clock. As a student, there will be a few people who stay to clean the class every day, and today, it happened to be Chen Mo's group.

"Chen Mo, haven't you had enough trouble in the afternoon?" Gu Yuxuan asked while sweeping the floor.

"Eh, it always feels wrong. I wanted to try to prove something, but ...... ”

"What exactly are you trying to prove?"

"You won't believe it."

"Then you should talk about it, you always sell off the guanzi to hang people's appetites."

Chen Mo said with a solemn expression: "There seems to be one less person in our class, but everyone, including you and me, doesn't remember the existence of this person. ”

"You...... No problem. Gu Yuxuan looked at the expression of a fool.

"Forget it, it's useless to tell you."

Gu Yuxuan shrugged his shoulders and grimaced, "I'm done, then I'll go." ”

Chen Mo turned his back to Gu Yuxuan and waved his hand. Gu Yuxuan returned to his seat and picked up his backpack. Walking to the door of the classroom, he looked back at Chen Mo. The cold white light hit his body, and his side face looked a little lonely and lonely at this moment.

"Or I'll wait for you." Gu Yuxuan stopped at the door.

"It's okay, you go, I have other things." Chen Mo replied calmly.

Gu Yuxuan shook his head and walked out of the classroom.

Night falls.

Chen Mo packed his schoolbag, picked up his schoolbag and prepared to leave the classroom. He looked out the window, there was only a row of street lamps on the dark path, which glowed slightly white, and there were a few students walking on the road leading to the school gate.

"Maybe, it's really me thinking too much." Chen Mo walked to the first row of the classroom and turned off the lights. As he turned the lights out, the classroom went dark. I couldn't see the moon today, and the clouds blocked the moonlight, so much so that I couldn't see my fingers in the classroom even after the lights were turned off.

"Buzz~Buzz~Buzz~" Chen Mo was just about to go out when he suddenly heard a sound coming from the dark classroom. This sound appears very abruptly, and if you listen closely, it is a bit like the vibration of a mobile phone.

"Whose phone was left in class?" Chen Mo didn't turn on the lights immediately, but looked for where there was the light of the mobile phone. It didn't matter, his heart shook when he saw the location of the light.

"This, isn't it, isn't it my seat!!" Chen Mo was very surprised, but he was still very calm on the surface, without the slightest fluster.

"No one came to my place in the afternoon, I cleaned up my desk before school, it couldn't have been my phone. I've been in class all the time while I'm cleaning, so it stands to reason that no one will touch my seat, let alone leave a phone on my seat. What's going on here!! ”

In a short period of time, Chen Mo reasoned all the possible situations in his mind, but none of them could reasonably explain the current situation.

"Is this a prank, no, no one should be so bored that they don't come home at night." Chen Mo turned on the lights in the classroom, and the classroom was lit up again. At this time, both the corridor and the classroom were very quiet, only the vibration of the mobile phone was buzzing. Chen Mo stretched out his head to look at the corridor, the corridor light had been turned off, and it was pitch black. After making sure that there was no one else, he walked to his seat.

The vibration of the phone kept ringing. Although Chen Mo has done so many things, it only took more than thirty seconds before and after. The seat near the window was his own, and next to it was an empty seat filled with his own books. Suddenly, the phone's vibration stopped. Silence returned to the classroom.

In a trance, he saw himself reflected in the window. Wearing a white school uniform with a backpack behind his back, he has a decadent expression and his trademark dead fish eyes......

"Don't say it, it's pretty handsome......"

For a moment, Chen Mo began to be self-indulgent, which was the first disease he would make every time he looked in the mirror. But in the next second, his dead fish eyes were round, and he saw it in the window, and saw another human face!! Because it was too far away, and I could only see the scene behind me through the glass in the window, I didn't really see it, but it was obvious that it was a woman's face!! The face is right outside the back door of the classroom!!

The hairs were raised, cold sweat seeped out of the palms of the hands, and the air seemed to freeze at this time. At this moment, Chen Mo remembered the scenes in the thriller he had watched. The female ghost stares at the protagonist and forces the protagonist into a dead end step by step......

"There was no one in the hallway! Who the hell is this person! Wrong!!! The back door was at least two meters high, and this face swayed against the secondary window of the door, facing the classroom, as if staring at me, so she was really ......?"

Even though Chen Mo is an atheist, he can't help but feel a little shaken in his own opinion after seeing the scene of the thriller in reality. Chen Mo had no way to give himself a reasonable explanation at this time, and used science to explain everything that was happening in front of him.

Chen Mo couldn't continue to think about it, because at this moment, the vibrating sound of the phone suddenly rang again. Chen Mo was frightened by this sudden vibration, and his eyes subconsciously moved away from the scene in the window and looked at the table in front of him. He shuddered and looked at the window again.

"Face! It's gone!!! Chen Mo looked back, but there was nothing on the secondary window of the back door.

"Calm down, calm down."

Chen Mo forced himself to calm down in his heart. "That thing must not be human, or rather not normal. Now she's gone, either she's still waiting outside the door, or she's gone. If she doesn't have ill will towards me, then she shouldn't worry too much, and if she has ill will towards me, she shouldn't be able to enter the classroom, after all, she doesn't have to pretend to be a ghost if she can come in. As long as I'm still in the classroom, it should be safe for the time being. Before you know exactly what is out there, take the phone in your desk to call the police, and then find a way to escape. Chen Mo silently analyzed how he should deal with such a situation in his heart. At this point, his eyes were fixed on the front door, to prevent anything from entering. His hands weren't idle, either, reaching for the vibrating phone under the desk behind him.

The position of the mobile phone was not very deep, and Chen Mo touched it as soon as he stretched out his hand. He held his phone in front of him and glanced at the caller ID quickly.

"Strange number, the number is very short, it should be a landline. The number is short! Wait a minute! Chen Mo picked up his mobile phone and quickly glanced at the caller ID again. 4444444！ What is this number!! Seven 4 !! Chen Mo's brain buzzed again. There are so many strange things that happened today, and he has never encountered so many unbelievable things in his 18 years of life.

"Seven 4s, this number is wrong, what the hell is going on!" He hesitated for a moment, feeling more and more that this matter was not simple, but he still reluctantly pressed the answer button.

"Hey." Chen Mo said.

In the mobile phone, there is not the slightest sound, and the silence is terrible.

"Hey, who are you looking for?" Chen Mo said again.

Time, as if standing still in this moment. Chen Mo, who was quiet, could hear his heartbeat. The feeling of suffocation pressed every nerve in Chen Mo, overwhelming him.

"Behind you." Two words suddenly came from the microphone.

Suddenly, the light flickered at this moment.

The moment Chen Mo heard these two words, his right hand holding the mobile phone froze in his ear, and slowly turned his head.
