Quick Travel: Who taught you how to attack villains like this?

Time flies, and the final exams are approaching in the blink of an eye.

During this period, the learning atmosphere in International (9) Class became extremely serious, and all this was thanks to Yu Yan.

However, behind this seriousness may be hidden the students' fear of her, but in any case, the result is gratifying.

As the great man said: "It doesn't matter whether the cat is black or white, as long as it catches mice, it is a good cat."

So, no matter what the students' reasons for studying hard are, as long as it improves their grades, other factors do not seem to matter.

The principal of Yuyang No. 9 Middle School had a very pleasant semester. Without the little devils from International () Class causing trouble, the campus seemed particularly peaceful.

For this, the principal publicly praised Yu Yan at several school meetings.

If it were someone else, they would have probably felt embarrassed because they could not bear such compliments, but Yu Yan always behaved very calmly and composed, as if the person being praised was not herself.

Yu Yan had just finished eating the fruit Liang Yan prepared for her, picked up her textbook, stood up, and said to Liang Yan: "I'm going to class."

"…So, am I sick again?"

Liang Yan looked at the textbooks and lesson plans in her hands, with a hint of hesitation in his eyes.

Every time he had an International (9) class, he always seemed to be sick, and this time he was sick for nearly two weeks.

Yu Yan did not respond, but just stared at him quietly with her textbook in hand.

Liang Yan understood immediately and nodded quickly, "Yes, yes, I'm sick and can't go to class. Yanyan, please go in my place! You've worked so hard."

Yu Yan smiled slightly: "It's not hard."

Ten minutes later, the students of International (9) class were looking forward to the next physical education class. However, when they saw their head teacher walking into the classroom, the smiles on their faces disappeared instantly.

Sigh...it looks like physical education class will be occupied again.

Yu Yan stood on the podium, looked around, and asked with a smile: "What's wrong? You don't seem happy to see me?"

Du Zhaohua immediately stood up and answered: "No! Teacher, you misunderstood. We are so happy."

Wang Ruohan also said: "Yes, yes, I like math class the most."

Now these two people have become Yu Yan's loyal supporters. No matter what task Yu Yan assigns them, they will carry it out without hesitation.

Just like now, as soon as Yu Yan finished speaking, they responded quickly.

When other students in the class saw this, they secretly curled their lips in their hearts, but they quickly adjusted their expressions and said that they also liked math class very much.

Humph, it’s just flattery, who can’t do it?

Yu Yan raised the corners of her mouth slightly and chuckled, then handed the papers she had just copied to the students sitting in the first row and said, "Please distribute these papers to everyone."

Then, she glanced at the whole class and said earnestly: "There is less than a week left before the final exam. I hope everyone can review seriously and strive to get excellent results in the exam. Okay, stop talking and start studying!"

Speaking of International (9) Class, there is one subject that stands out the most, which is quite surprising.

Yes, mathematics!

You know, the math scores of International Class (9) were the worst before, with an average score of less than 20 points, and two-thirds of the students even got the first multiple-choice question wrong.

It is really unexpected that they can now achieve excellent results in the subject of mathematics.

In fact, all this is thanks to Yu Yan.

She had learned all kinds of knowledge in so many mission worlds and even lived in the interstellar plane.

The knowledge reserves in her mind are like an endless treasure house, inexhaustible.

When it comes to teaching, Yu Yan has a unique method.

She can always teach students how to solve problems in the simplest and clearest language, making originally complex and difficult problems easy to understand.

Just a while ago, the school organized an open class activity for the mathematics group, and Yu Yan was randomly selected as the teacher of the demonstration class.

After listening to her math class, the teachers present were amazed at her teaching level and said she was a natural teacher.

From then on, students from other classes often ran to Yu Yan's office during breaks to ask her math questions.

If he wasn’t afraid of the people in International (9) Class, he might have chased them to the classroom.

Yu Yan walked around the classroom and was very satisfied to see that they were all doing their homework diligently.

At this moment, there were suddenly screams coming from the playground, one louder than the other, as if something terrible had happened.

After hearing the sound, Yu Yan quickly walked to the classroom window and looked towards the playground.

On the playground, a bearded, crazed man was holding a huge machete and rushing towards the students who were having physical education class like a ferocious beast.

His movements were crazy and out of control, and every blow carried a deadly threat.

Upon seeing this, the school security guards picked up their shields and tried to stop the madman.

However, the machete was too long, and the security guards' shields could not completely block his attack, but could only temporarily slow down his pace.

The teachers were also anxious to protect the students. They tried to guide the students to flee the scene, but the frightened students had lost their minds and were running around screaming. The teachers were simply unable to take care of all the students.

The scene was in chaos, with the children's terrified screams and the adults' nervous shouts intertwined, making people feel extremely frightened.

Yu Yan frowned and immediately ran out of the classroom and ran towards the playground.

The students who were doing papers in the classroom were stunned by this sudden action.

They also ran to the window and looked outside, and saw the madman who was slashing people with a knife.

"Oh my god! What's going on? How did a lunatic sneak into our school?"

"What about those people on the playground? They won't get chopped down, will they?"

"Call the police, call the police!"
