Knock knock.

The knock on the door continued.

Xu Yi didn't dare to go out, so he had the courage to shout: "Who?" ”

No one responded.

The knock on the door rang again.

Knock knock.

Heavy and depressing, continuous.

Xu Yi was a little panicked and pushed his roommate next to him.

The roommate was pushed awake and said angrily: "What are you doing?" ”

Xu Yi leaned into his roommate's ear and whispered, "Someone is knocking on the door."

The roommate pricked up his ears and didn't make any sound.

The roommate frowned and said unhappily: "Why is there any knock on the door, sleep, and there is still class tomorrow?" ”

The roommate grabbed the quilt, covered his face, and fell into a deep sleep.

Xu Yi listened attentively, and the knock on the door sounded again.

Knock knock

Two times at a time, three times at a time.

Heavy and oppressive, like a hammer striking his heart.

Xu Yi didn't dare to listen anymore, so he simply covered his ears and got into the bed.

Nothing was said all night.

The radio on the playground sounded.

"Good luck comes, we come with good luck, and good luck prospers through the ...... of the four seas."

The roommates got dressed and got up one after another.

A roommate patted Xu Yi's quilt and urged: "Get up quickly, otherwise you will be late."

Xu Yi pushed off the quilt covering his head, opened his hazy eyes, rubbed his swollen eyes, and sat up.

The roommate looked at Xu Yi's swollen eyes and exclaimed, "Why are your eyes swollen like a peach."

Xu Yi yawned and said weakly: "Didn't sleep well last night?" ”

The roommate nodded and said, "I was woken up by you last night."

The roommate urged again: "Hurry up, I'm going to do morning exercises."

Xu Yi was surprised: "What do you do morning exercises?" ”

The roommate said: "Today Monday, I want to raise the national flag and do morning exercises."

Xu Yi hurriedly got up, got dressed, washed up, and then went downstairs with his roommate.

It's spring.

The morning weather was slightly cold, and a waning moon hung in the sky.

After raising the national flag.

Accompanied by the sound of radio gymnastics.

The students lined up in a neat line followed the rhythm of the radio and began to dance and do radio gymnastics.

After gymnastics.

The students lined up in a neat queue and stepped into the classroom in an orderly manner to read in the morning.

Xu Yi spread out the book, and the knock on the door kept echoing in his mind.

Knock knock

Two times at a time, three times at a time.

Suddenly, the energy-saving lamp overhead flickered.

The students' recitations came to an abrupt end.

Everyone looked up at the flickering energy-saving lamps overhead.

The teacher picked up the thermos cup and took a sip of water.

Bang.

The classroom door slammed shut, and the noise was very loud.

Both the students and the teachers were taken aback.

The lights in the entire school building went out.

Half past six in the morning.

The sky is white, and the vision is gradually clear.

However, the classroom was dark, and it was impossible to read the words on the books.

There's a power outage.

The classroom was in an uproar, and the students screamed with joy.

The teacher slapped the table and scolded: "Be quiet, give me silence."

The classroom immediately fell silent.

The teacher said, "Don't talk, you'll be calling soon."

The students were silenced.

Knock knock.

There was a knock on the door.

Two times at a time, three times at a time.

It was like a hammer striking on Xu Yi's heart.

Xu Yi's eyes widened and he said in surprise: "It's this kind of voice."

All the students turned their heads and looked at Xu Yi in unison.

Xu Yi smiled awkwardly and explained, "It's okay, it's okay."

The teacher stepped down from the podium and opened the classroom door.

There was nothing outside the door, the teacher looked out, and there was no one in the hallway.

The teacher in the next classroom also poked his head out.

The eyes are facing each other.

The teacher asked, "Teacher Chen, did you hear any sounds?" ”

Teacher Chen replied, "I heard a knock on the door."

The teacher nodded and said, "I heard it too, but I just opened the door and there was nothing."

Teacher Chen was puzzled: "I didn't see anything when I opened the door, it's really strange."

The two teachers smiled at each other and walked into the classroom.

Suddenly.

Bang.

The classroom door slammed shut.

Both the students and the teachers were taken aback.

Some students whispered, "Did we encounter a ghost?"

The table mates retorted: "Shut your crow's mouth, don't talk nonsense".

Knock knock.

There was a knock on the door.

Two times at a time, three times at a time.

It's like a needle in the heart of all students and teachers.

The teacher couldn't help but take a step back.

The teacher picked up the thermos cup on the table, took a sip of water, and suppressed the panic.

Knock knock.

There was a constant knock on the door.

The teacher poured a few mouthfuls of water, took out his mobile phone from his pocket, and dialed the head teacher: "Teacher Wang, something strange happened in your class, the classroom door is always closed for no reason, and there is always a knock on the door."

The teacher took out his mobile phone and pointed it at the classroom door.

Knock knock.

Two times at a time, three times at a time.

It is transmitted into the mobile phone very frequently.

Mr. Wang was a little scared and said, "There was a knock on the door of my house, and the door of the office was closed for no reason."

The teacher was surprised: "What should I do then?" ”

Teacher Wang said: "You reassure the students first, the principal has called the police, the police will come soon, don't worry."

The teacher nodded and said, "Okay, you can rest assured on the student's side."

The phone hangs up.

The teacher listens to the knock on the door.

Knock knock

Two times at a time, three times at a time.

A creepy feeling suddenly surged in the bottom of my heart.

The teacher picked up the thermos cup, poured a few sips of water again, and said calmly: "Don't be afraid, sit down, the principal has called the police, and the police will come soon."

The students were calmed down, and the teacher sat down on the podium.

Knock knock.

The knock on the door kept ringing.

The teacher didn't dare to open the door again, so he simply couldn't see it out of sight and was not upset, picked up the headphones, stuffed them into his ears, listened to the song, and read the novel.

He opened the reading app and clicked on the suspense novels he often reads: I was raised by ghosts.

When he caught up with the latest chapter, he was surprised to find that the plot in the novel was strikingly similar to the scene today.

The teacher swallowed and stared intently at the page of his phone.

When you get to the last chapter, the page is blank, indicating that the author is still working on it.

The teacher was surprised in his heart: "This author is divine, and the content described is exactly the same as the current scene."

The teacher looked at the rattling classroom door with a hint of fear in her eyes.

The police station that received the alarm immediately dispatched two police cars and drove quickly towards the alarm location.

Two police vehicles drove into the campus.

Heavily armed police officers stepped down.

The school was empty, and not a single student or teacher was in sight.

A policeman asked, "Team Liu, are we in the wrong place, why is there no one here?" ”

Team Liu called the police station and asked, "Little Sun, is there a mistake in the location of the police, we arrived at the school and didn't find a single person."

Xiao Sun said: "Captain Liu, please wait a moment, I will immediately look up the phone records and ask what the situation of the person who called the police is?" ”

Team Liu said: "Okay, you hurry up."

Xiao Sun said: "Don't worry, Team Liu."

Ten minutes later.

Xiao Sun called: "Captain Liu, have you arrived at the No. 1 Middle School in County A?" ”

Team Liu said: "The No. 1 Middle School in County A, that's right."

Xiao Sun said: "That's strange, the police said that they were in the No. 1 Middle School of County A."

Team Liu asked, "Tell me, what happened to them?" ”

Xiao Sun said: "All their teachers and students are trapped in the classroom, the whole school has a power outage, and there is always a knock on the door in the classroom, open the door, go out to see, and there is nothing, and then they have no choice, so they choose to call the police."

Captain Liu said: "That's all? ”

Xiao Sun said: "That's all."

Captain Liu said, "I know."

The phone hangs up.

Captain Liu looked around, looked at the empty campus, already had a plan in his heart, and muttered, "They should be hitting ghosts."
