After finishing the first class of the morning listlessly, the small loudspeakers installed in each classroom suddenly went off without warning.

Moreover, the speaker was not a teacher from the grade, but a vice principal in charge of the entire school.

Before many people even realized what was happening, the vice principal, speaking in the local dialect, said: "Students, according to a notice from higher authorities, due to a case of COVID-19 infection in our city, our school will switch to online learning starting today."

Grade leaders and homeroom teachers are requested to coordinate the order of each grade and class, and in accordance with the school's arrangements, pack up their personal belongings in batches and leave the school in an orderly manner.

Classes that are not scheduled will continue as normal, following instructions broadcast over the loudspeaker, and completing nucleic acid testing…

The subsequent broadcast included many related precautions, but the commotion throughout the school drowned out these remarks.

Taking Chen Bing's class, the 12th class of the second year of high school, as an example, many people couldn't help but raise their arms and shout after hearing the news that they could go home to take online classes.

Although they had suspected this before the broadcast, based on the phone call Chen Bing had made last night, they were still delighted to hear that it was true.

Studying? What the hell are you talking about! Hurry up and pack your things!

Despite his thoughts, the fierce-looking homeroom teacher, Hu Jianjun, still managed to suppress the restless atmosphere in the class with his iron-fisted methods.

"Shut up! What's all the noise about!" Two minutes after the bell rang for the second period, Hu Jianjun stood at the classroom door and roared angrily, slamming his lecture notes onto the lectern, kicking up a cloud of white dust.

Upon seeing this, the class instantly fell silent, and everyone's face wore expressions of fear and resentment.

After calming the restless atmosphere in the class, Comrade Hu Jianjun, who was skilled at managing the class, gave everyone a sweet treat.

His fierce face changed in an instant; just a moment ago he looked menacing, but in the blink of an eye he became gentle and kind.

"I'm not saying I want to lecture you students, I just want you to know what you should do and when. When I got home last night, I received an urgent notice from the school to attend a meeting, and then I rushed over and the meeting lasted until 2 a.m. All the measures have been arranged, so there's no use in you being anxious now."

Our class is scheduled to leave school at around 3:30 pm, and it's only 9:00 pm now, so there's no need to rush to pack your things. The teacher will give you plenty of time.

Su Xun of the Northern Song Dynasty said in his book "Xin Shu" that "one should not change color even if Mount Tai collapses in front of him." Our class is a liberal arts class, and it is also a key liberal arts class. There are top students like Chen Bing and Shang Yunmiao, as well as hardworking students like Cao Siying and An Letong, and so on. I will not list them all here.

I think everyone should learn from these students: be down-to-earth, steady, diligent, and hardworking. Let's establish a good class atmosphere and set a good example for other classes on the same floor, so that they won't laugh at our so-called key liberal arts class for being worthless.

Okay, I won't go into too much detail. Everyone, turn to page 45 of your geography books. Today we'll continue with our new lesson.

After saying that, he wrote the course title on the blackboard and began lecturing with a calm and collected demeanor, just as he had described, showing no change in expression even if Mount Tai collapsed in front of him.

Although they had just caused some trouble, they were, after all, students in a top-tier humanities class, mostly girls, and their grades were quite good. Furthermore, after a whole semester of Hu Jianjun's superb class management skills, and the gradual influence of academic geniuses like Chen Bing, everyone was somewhat inclined towards studying.

So after the initial excitement, most people at least pretended to calm down and started attending the class.

Among the chaotic and restless classes on the same floor, Class 12's unique atmosphere drew praise from many passing teachers and students. As Hu Jianjun said, everyone lived up to the reputation of being a key class.

Shortly after geography class ended, the students took their health codes and went downstairs to line up for nucleic acid testing. Upon returning, they remained relatively calm and continued attending class, gradually concluding the morning's lessons.

Throughout this process, Shang Yunmiao showed no signs of restlessness whatsoever. She simply did what she always did, attending classes, taking notes, and doing exercises in a very obedient manner.

After the morning classes were over, which was just before the short self-study session, Hu Jianjun came to inform everyone that they could line up to go to lunch. After lunch, they were to go back to the dormitory to pack their things. After packing, they were not to take a lunch break, but to go straight back to the classroom to pack their bags and prepare to leave the school.

Unable to contain their joy any longer, everyone cheered, put on their masks, and then lined up in a long queue outside the classroom to go eat.

It can only be said that Xiao Shang is indeed Xiao Shang. Before leaving the classroom, she had the foresight to anticipate that queuing for food would take a long time, so she specially brought a pocket book to study while waiting.

Occasionally, when she encounters some knowledge points that she doesn't quite understand, she will tilt her head and ask Chen Bing, who is standing next to her, for help.

Chen Bing, on the other hand, had to bend down and press his face against Shang Yunmiao's to read the pocket book because the print was too small.

Just then, a teacher who was patrolling the hallway and managing the queuing order passed by. When he noticed the man and woman standing so close together, he instinctively wanted to reprimand them.

But after recognizing the two people, he changed his mind and prepared to remind them to keep a meter apart.

But after glancing at the pocket book in Shang Yunmiao's hand and recalling the recent news that the principal was going to be promoted to director of the education bureau, the words that were about to come out finally changed to: "Look at Chen Bing and Shang Yunmiao! They don't forget to study even when they're queuing up. You should learn from them!"

After saying that, the teacher continued walking forward without looking back, leaving the somewhat bewildered students of Class 12 behind.

At that moment, a boy looked up at Chen Bing and Shang Yunmiao's actions, then suddenly grinned mischievously and pressed himself against his friend, calling out in a sweet voice, "Guigui~ take out your pocket book, I want to read it too~"

His affected manner immediately amused the other students in the class, but it also attracted the attention of the teacher from before.

He turned around angrily, glaring at the two men and yelling, "Keep a meter apart! I told you to learn from others, not to do this!"
