When it came, the second class of the second year of high school was taking a chemistry experiment class, and the substitute teacher was Wu Hao.

The school's experimental classes are taught in the experimental building, which is close to the road and has only four floors, and the classroom used in the second class of the second class of high school is on the top floor of the experimental building, a classroom at the end of the corridor.

The rain outside the window was terrible, in Wu Hao's memory, he rarely saw such a heavy rain, this rain made Wu Hao a little uneasy, after telling the students about the precautions of the experiment, Wu Hao walked to the window and looked at the heavy rain outside the window.

Outside the window, the thunder continued, the rain poured down, many students were also disturbed by the heavy rain, some students simply put down the flask in their hands, lying on the window and lamenting that the rain was really heavy.

Wu Hao glanced at the classmates who left the test bench without authorization, and did not urge them to go back, the classmates were also interested, and after watching for a few minutes, they all went back to do experiments, after all, when class ended, Wu Hao still had to receive the experiment report.

The rain had been pouring for half an hour before it stopped, and at the end of class, there was a loud scream from downstairs, which was only one or two at first, and after a few minutes, more and more people began to scream.

Wu Hao even heard the voice shouting for help from those voices.

This is the school, such a scream is very unusual, and when the screams became more and more, Wu Hao, who was inspecting the classroom, stopped his inspection, he walked to the window and looked downstairs.

The courtyard downstairs was already in chaos, some people were lying on the ground without knowing life and death, some people were running after others, and some people were thrown to the ground, and the one who fell down was biting on the person who was thrown down, whether it was the person being chased or the person who was knocked down, they were screaming.

Something happened!

Wu Hao's heart tightened, the people downstairs were already in chaos, there were students and teachers among those people, but no one stood up to maintain order, whether it was a student or a teacher.

Everyone was busy running for their lives.

The movement downstairs attracted Wu Hao's attention, and naturally also attracted the attention of the namesake.

Several students saw that the teacher was looking downstairs, so they had the courage to lie down by the window and look downstairs.

"What happened?" Seeing the chaotic classmates downstairs, there was no concentration of Wu Hao, and some people were scared to see it, so they subconsciously asked.

This question did not arouse the curiosity of more students.

Everyone leaned on the windowsill and looked downstairs.

"Oh my God! Yes...... Someone is ...... Cannibalism! ”

"What happened?"

"I don't know ...... either"

"I'm so scared of ......"

"What are we going to do?"

……

……

Seeing the chaos downstairs, many classmates were frightened, and some timid girls cried directly.

The students were so noisy that they couldn't make up their minds for a while, and some of them wanted to escape from here first and find a safe shelter.

Wu Hao knew that the current chaos was downstairs, and it might not take long for those terrible things downstairs to spread back upstairs, and he stood upstairs and could see clearly that there was no safe place downstairs now.

Instead of running out and slamming around like a headless fly, it is better to stay quietly in the laboratory and wait for the situation to further ferment.

Maybe he'll see how this matter was solved if he looked at it more.

At any given time, panicking will not solve the problem and will only make things worse.

Only by calming down can we find a way out of the dead end.

"Classmates."

Facing the classmates who were messed up into a pot of porridge, Wu Hao spoke up, his voice was very magnetic and unusually calm, as soon as such a voice came out, the students who had no clue quieted down one after another.

Wu Hao walked to the podium and continued: "The horror that happened downstairs, everyone can see it, although we don't know what happened, but the most important thing now is to protect ourselves, everyone here is my students, I don't want any of you to have anything, downstairs has become a hell on earth, you may not find a safe place and encounter danger when you run out now, so, in order to protect everyone, the safest way now is for us to stay here, everyone don't make a sound, Block the doors and windows with the experimental table, don't let any danger come in, the students with mobile phones call the police first, and then check if there is any relevant news on the Internet, we have collected enough information, and then make the next step. ”

Wu Hao's words were clearly organized, and Wu Hao had a good status among the students on weekdays, at this time, Wu Hao's opinions were completely unopposed, and the class cadres took the lead in moving the heavy experimental table, blocking the heavy experimental table behind the doors and windows, and everyone felt more at ease.

"Teacher, 110 is busy, and 120 and 119 are also busy."

After moving the table, the classmate in charge of the call reported an unfortunate message.

There was chaos in the school, and everyone stood on the fourth floor and looked down at the street, and the street was not very peaceful, and although the chaos was not as serious as in the school, it was very similar.

Wu Hao looked at the chaos everywhere and guessed that this chaos must be very big, otherwise 110, 120 and 119 would not be out of reach.

"Check the situation online first."

Wu Hao was in a deep voice, he was still observing the situation downstairs, and he saw that someone had already rushed to the experimental building in a panic, followed by a group of people with green faces and fangs.

Seeing this situation, Wu Hao hurriedly instructed the students: "Someone will come up in a while, everyone blocked the doors and windows, don't make a sound, no matter who it is, don't let it in!" ”

"We can't save people without weapons in our hands!"

What will happen in a while must be very cruel, Wu Hao was afraid that these students who were not deeply involved in the world would do irrational things under the impulse, so he specially ordered it.

Hearing the teacher's instructions, the classmates, who had long been frightened, trembled and remembered together, not daring to speak out or speak.

Soon, someone ran to the fourth floor, and the students who were being chased screamed for help in a heart-rending manner, followed by inhuman roars.

Listening to those roars, some timid students were frightened and cried again, and the students next to them anxiously covered the mouths of the crying students.

Outside the door, a girl was chased and cornered, and ran to the door of the laboratory where the second class of high school was located, she wanted to come in and hide, but she pushed hard a few times, but failed to push the door open.

Seeing the zombies behind her, the girl screamed in despair while banging frantically on the door of the laboratory.

"Is there anyone in there? Open the door, please, help me! Help me! Ah......h

"Help......

However, no matter how the girl slapped it, the door blocked by the laboratory table did not move.
