The two dogs were silent, and the classroom suddenly became dead silent, and the three of them looked at each other and found a chair for each other to sit down. They waited anxiously for twenty-four hours to pass quickly.

After a while, Zhang Xiang's sobs rang out from the corner.

"It's noisy!" Li Ao was distraught, and casually picked up the summer vacation homework on the podium and threw it in Zhang Xiang's face.

"Scared? If you have nothing to do, you can write this summer homework! Li Ao said, throwing the summer vacation homework and ballpoint pen on the podium to Zhang Xiang.

Zhang Xiang, a high school student, cried and opened his summer vacation homework with a ballpoint pen and wrote with relish.

Elementary school students' math summer homework is a piece of cake for Zhang Xiang.

He turned all his attention to his homework, and for a moment he actually forgot about the horrors of the outside world.

The classroom was silent again, except for the rustle of ballpoint pens on paper.

"29 plus 57 equals ...... Equal to 87! Zhang Xiang wrote to Xingtou and shouted excitedly.

Ao Yuanjie couldn't help but roll his eyes, is 29 plus 57 87? It's 76!

Although Ao Yuanjie despised Zhang Xiang in his heart, he didn't say it, he was so scared that his thighs trembled now, where could he take care of other people's miscalculations.

"What a noise!" Li Ao slapped Zhang Xiang's head, "Do you want to attract monsters?" ”

Zhang Xiang raised his head, and an imperceptible trace of hatred appeared in his frightened eyes, which was quickly overwhelmed by fear.

Zhang Xiang lowered his head and continued to immerse himself in learning. In this space of fear and trial, only familiar books and learning can make up for his wounded heart.

Outside the door, the second dog was gnawing on the leash.

The belt is fragrant and new, and there is still a faint smell of meat on the belt, and the belt is made of pure cowhide.

The second dog lay on the ground and gnawed comfortably on the leash. Its teeth had cracked into the belt, which had become tattered after five minutes of biting. As long as the second dog struggles at will, it can break free from the shackles of the leash.

It whined and gnawed along the gap in the belt all the way up, and in less than a moment, the exposed part of the belt outside the door had been gnawed by the two dogs until only a strand remained.

The breeze was blowing, and the cowhide was gnawing. Ergou has forgotten his original purpose of gnawing on the leash.

Ergou raised his head and looked at the belt in the crack of the door. Its stomach wasn't full yet, but it couldn't think of any way to eat the belt in the crack in the door.

The sound of heavy breathing outside the hallway became louder and louder,

Ergou felt that the floor seemed to shake a little, and he lowered his head and put his ear to the floor, listening carefully.

Dada~

The vibration from the floor became clear in Ergou's ears, and it was the sound of leather shoes stepping on the floor.

The sound is a little blurred and is getting closer.

It took three minutes for the second dog to put his ears on the floor and make out that the sound was coming from the east side of the hallway.

As soon as it looked up, it saw a man in a plaid suit walking less than fifty meters away from the east side of the corridor.

The checkered man was extremely ugly, his head drooping to the side, and his calloused left hand was holding a large hammer. In his right hand dragged a person, who was none other than a survivor who had appeared in the classroom earlier - Liu Yuan, who was shouting to kill the monster.

Liu Yuan's life and death are unknown, and the mountain opening knife in his original hand ran to his back, and the blade was more than half in. His head was flattened as if it had been squeezed by a door.

A trail of blood dragged from underneath him, and the fresh blood in the trail was absorbed by the cracks in the floor and melted into the ground.

Oh, it turns out that it's been so close.

"Wow!" The second dog barked and then turned around and ran.

Ergou forgot that he was wearing a leash around his neck.

"Click!" The tongues of the two dogs were strangled.

The belt broke in response, and the second dog fell to the ground, and a dog ate.

A puddle of blood on the ground made Ergou's legs and feet slip, and it just got up and fell on the floor, Ergou's head hit the wall, and it fainted directly.

The second dog entered a coma.

"What sound?"

The barking of the two dogs immediately aroused the alarm of the three people in the classroom.

Li Ao tried to open the front door, but found that he had wrapped the belt around the doorknob of the front door, and with the strength of the second dog, he took the belt out a little, directly causing the belt to jam the crack of the door. Li Ao and Ao Yuanjie couldn't open the front door no matter how hard they tried.

Since the front door can't be opened, the back door can only be opened.

But dozens of desks and chairs at the back of the classroom nearly blocked the back door. If they wanted to open the back door, Li Ao and the three of them had to spend at least ten minutes cleaning up.

"! Open it for Lao Tzu! Li Ao yelled angrily, kicking the front door one after another.

The sound of a knock on the door reached the hallway.

The checkered man who dragged Liu Yuan let go of Liu Yuan's body, and he walked straight to the classroom where Li Ao and the three of them were. He ignored the second dog who was unconscious at the front door, raised the sledgehammer with both hands, and smashed it at the outer wall in the middle of the classroom.

There was a clang, and the wall of the classroom was smashed with a hammer to create a large hole for one person to pass.

Li Ao and the other three were completely exposed in front of the man in checkered clothes.

Zhang Xiang writes his homework very quickly, and he can finish a page in a minute. He couldn't help but sigh in his heart: "If only the questions in the college entrance examination were as simple as this......

When the checkered man broke through the wall, Zhang Xiang happened to write the last page of his summer vacation homework.

"Ahhh Zhang Xiang shouted.

Zhang Xiang screamed as he continued to write his homework with a ballpoint pen.

This is a habit he has developed since he was a child, as long as he starts to write his homework, and if he doesn't finish his homework, he must not give up halfway.

Zhang Xiang's position was the closest to the man in checkered, only a short five meters away.

The checkered man turned his head, his ugly face expressionless. He walked towards Zhang Xiang step by step.

"Li Ao, shoot quickly!" Ao Yuanjie was the first to react, and he yelled at Li Ao.

Li Ao kept kicking the door, he stared blankly at the checkered man who broke through the wall, and he was directly scared stupid.

"Mom and Dad!" Zhang Xiang cried and screamed. He bent down and bowed his head, but the ballpoint pen in his hand still didn't stop. The sledgehammer in the checkered man's hand flew right past his scalp.

And at this time, Zhang Xiang's summer vacation homework was finally completed.

The man in the plaid clothes stretched out his stiff right hand, grabbed Zhang Xiang's throat, who was about to escape, and lifted him up directly.

Zhang Xiang kicked and kicked the man in check, but the man in checkered did not react. He slowly raised the hammer and aimed it at Zhang Xiang's head.

"Shoot!" Ao Yuanjie shouted.

Li Ao's hands trembled, he raised his pistol, closed his eyes and shot at the checkered man and Zhang Xiang.

"Smack! Syllable! Syllable! Syllable! Syllable! ”

The sound of gunfire echoed through the classrooms.

Li Ao's marksmanship is suffocating. Only two of the five rounds of the pistol hit, one of which hit the man in checkered clothes and another hit teammate Zhang Xiang. The checkered man's right shoulder was hit by a pistol, and he let go of his palm that grabbed Zhang Xiang, and staggered several steps, but quickly stood up straight, as if nothing had happened.

Li Ao still wanted to shoot, he continued to pull the trigger of the pistol, but the pistol did not fire. The five bullets of the pistol had been completely shot by Li Ao in an instant.

Zhang Xiang was hit in the upper arm of his left hand by a pistol bullet. He clutched his arms and screamed in pain. He stooped and ran behind the checkered man, crying through the hole in the wall that had been pierced, and ran down the east side of the hallway.

"Ahh

Zhang Xiang's screams came from the corridor again, and Liu Yuan, who had become a cold corpse, frightened Zhang Xiang again.

The checkered man set his eyes on the remaining two people in the classroom.

"What should I do?" Li Ao, who had always been very confident, had no master at the moment, like a mentally retarded person.

I saw Ao Yuanjie raise a table and smash it towards the man in checkered clothes. Although the table did not cause damage to the checkered man, it slowed down the checkered man's movements.

Ao Yuanjie ran away, although he was obese, he was very flexible. He was the second to burrow through the hole in the wall behind the checkered man.

When Ao Yuanjie passed by Liu Yuan's corpse, he pulled out the mountain knife on Liu Yuan's back. He ran down the stairs eastward down the hallway, taking advantage of the dim light.

"Wait for me!" Li Ao's legs trembled, he gritted his teeth, and slapped a swift talisman handed over to him by Ao Yuanjie on his leg.

The runes on the swiftness talisman immediately lit up, and a red light melted into Li Ao's legs.

At this moment, the man in the plaid clothes reached out and grabbed Li Ao's arm. Li Ao suddenly felt a sharp pain coming from the base of his arm, and he screamed and ran out along the hole in the wall.

The swift charm provided Li Ao with rapid speed, and Li Ao quickly ran away.

The checkered man turned around and chased in the direction of the trio's escape, step by step.
