The intern taught a top-performing class, and the parents wanted to change the homeroom teacher.

The whole class stared wide-eyed.

There was an even bigger surprise!

They cheered.

Lu Qian spoke up, "Quiet down, quiet down!"

He then pointed to Sun Fu beside him and said, "This is Mr. Sun, the owner of the supermarket. Most of you know him. He gave me a 30% discount and helped me carry it upstairs. Hurry up and thank Mr. Sun."

The whole class cheered excitedly.

"Thank you, Teacher Lu. Thank you, Boss Sun."

"Teacher Lu is awesome! Boss Sun is so generous!"

"May Boss Sun's wealth increase and his life be prosperous and worry-free!"

"..."

The voices were uneven, but filled with joy and excitement.

Mr. Sun couldn't stop smiling; being with these children made him feel several years younger.

Lu Qian handed out snacks, saying, "Take whatever you like, but I have two requirements: be quiet! And don't litter!"

Before leaving, Boss Sun said again:

"I've worked at the supermarket in Yu-Cai for so long, and this is the first time I've encountered a teacher who buys snacks for the whole class."

Study hard and don't let your teacher, Mr. Lu, down.

On the day of the college entrance exam, whoever gets a high score can come to my supermarket and have all the snacks and drinks they want!

The whole class responded loudly.

The movie continued, and Lu Qian also came to the back with potato chips and spicy strips to watch the movie together.

He has watched Interstellar many times; this is his fifth time watching it.

But I still never get tired of watching it.

As the plot entered its main storyline, the whole class became even more engrossed.

……

On the other side, Class 7.

As Zhang Chao read out his math test score, his expression softened considerably.

My math test score was pretty good; I was right to teach him.

"Zhang Sisi 145... Zhao Qihang 135..."

Zhao Qihang, who had been tense the whole time, immediately breathed a sigh of relief.

Fortunately, the score was five points higher than the last weekly test.

If I get a low score, I won't be able to explain it to my family when I get home.

As for getting problem-solving ideas from others during exams, he completely forgot about it.

In his view, he just lacked a bit of ideas, but now he has completely mastered it.

So when Zhang Chao explained the problem and asked the class if they knew how to do it, the whole class answered in unison, "Yes."

The test paper was quickly finished, and Zhang Chao felt a sense of relief.

Teaching a top-performing class is so comfortable; I don't have to explain things over and over again.

"Alright, go study on your own." Zhang Chao said, then returned to his seat on the podium.

Many students in the audience were overjoyed.

I finally have some free time to do my homework.

Compared to when Lu Qian was in charge of the class, the amount of homework now is simply mountainous!

Zhao Qihang nudged Chen Yu, the English class representative sitting in front of him, without saying a word, but instead hunched over and pointed to his English test paper.

The meaning is simple: I can copy your test paper.

Chen Yu readily handed over his exam paper.

Zhao Qihang immediately began copying extensively.

When Lu Qian was in charge of the class before, he assigned very little homework, which made it easy for him to complete and remember the lessons very clearly.

Now that we have a new homeroom teacher, the amount of homework has increased exponentially.

He didn't want to waste time on these assignments; he wanted to go back and play games that night.

I could write until late at night just by myself, since I already know it all.

As long as you listen attentively in class, homework isn't that important.

If all else fails, you can listen to it again in your senior year of high school; it will be explained again anyway.

There are many students in the class who share his ideas.

Nobody wants to stay up late doing homework. These mindless tests can be copied directly, and then you can just listen attentively in class the next day.

……

Class 25 continued watching the movie quietly.

The film is very long, 2.49 hours.

During the break between evening self-study sessions, no students wanted to go out to play. Those who couldn't hold it in any longer went to the toilet in a hurry and came back in a hurry as well.

Students from the neighboring Class 24 who were out for a stroll noticed something amiss.

Why is Class 25, which is usually bustling, so quiet and closed today?

Several students came to the door, looked through the window, and their eyes widened in surprise.

"Holy crap, Class 25 is watching a movie!"

"What sci-fi movie is this? It looks pretty cool!"

"Watching a movie and eating snacks at the same time, how awesome is that!"

"Is it too late to transfer classes now?"

"..."

The noise at the door was a bit loud, attracting the attention of the students inside who all looked towards the doorway.

Seeing the envious looks on the faces of students from other classes, the students of Class 25 felt a strong sense of satisfaction.

You don't have it, but we do!

Envy?

I'm not even envious!

As the film progressed, the high-energy moments continued, especially when the character rushed into the black hole, the whole class kept gasping in surprise.

I watched it all the way to the end.

The male protagonist returns from the black hole still in his prime.

The daughter who resolved the crisis in her home was now a 98-year-old woman with gray hair.

The power of time was fully demonstrated at this moment.

"Smack."

The movie ended, and Lu Qian turned on the lights.

The whole class was somewhat dazed.

"How is it? Would you call it a blockbuster?" Lu Qian asked with a smile.

"This is absolutely stunning!"

"Is this another way of going back to the past?"

"This creates a closed loop; it doesn't change the future at all."

"It's not a closed loop; everything you do is part of the future!"

"When I get home, I'll check my bookshelf to see if my future self has left any hints for me."

"If you find any hints for the college entrance exam answers, remember to share them with me."

"..."

The classroom was filled with lively discussions.

"Quiet," Lu Qian said.

The room immediately fell silent.

"You can ask the physics teacher about these things tomorrow."

"By the way, the scientific advisor for Interstellar was a real physics giant, Kip Thorne, who won the Nobel Prize in Physics in 17."

Exclamations of surprise echoed from inside the house.

"You think this is the most shocking thing?" Lu Qian smiled mysteriously. "Interstellar was released in 2014, and the shape of the black hole in it was calculated by Kip Thorne."

"Furthermore, the image of the black hole was only taken in 19, a five-year gap!"

"So study math, physics, and chemistry well, because they really won't lie to you."

These words shocked the entire class even more.

Black hole: Opened?

"Awesome math, awesome physics!"

"Mathematics doesn't lie to me, I truly believe that, because if I don't know it, all I can do is write down 'solution'."

"..."

Ten minutes later.

After evening self-study.

Compared to the tired and sleepy faces of students in other classes, all the students in Class 25 looked relaxed and happy.

Xie Tianming and several classmates walked towards the gate of the teaching building. His former junior high school classmates gathered around and asked curiously.

"Tianming, I heard you went to see a movie tonight?"

Xie Tianming said proudly, "Yeah, our homeroom teacher gave us these, and even paid for the snacks out of his own pocket. Everyone in the class got some!"

"Damn, this is awesome!"

Other students passing by also cast envious glances.

While other students are having evening self-study sessions, they watch movies and eat snacks, all paid for by the homeroom teacher out of his own pocket.

In my class, evening self-study sessions are either classes, exams, or self-study and homework. Some homeroom teachers are so strict that you can't even look them in the eye!

They're both homeroom teachers, so why is there such a big difference?

Xie Tianming and his classmates felt a surge of relief!

Just then, an untimely voice rang out.

"Watching movies and eating junk food during evening self-study sessions, no wonder the class is the worst in the grade, a gathering place for bad students."
