After handing it over to the system, the three brothers knelt down and begged for forgiveness

Upon hearing this, Nan Qiao raised her eyes slightly, with a hint of strangeness in her eyes, and she showed no intention of getting up.

Wang Xiaoxuan was so angry that her eyebrows raised and she retorted loudly, "Why? We came so early just to get a good seat. How can you say that just because it's yours, it's yours? Don't bully others by taking advantage of your power!"

"What do you know? Professor Lin is here just for Sister Xue's sake. He came here specifically to give Sister Xue a lecture. Why are you being so conspicuous here?"

"You only want to teach Lan Xuxue? Then you can be her tutor and teach her alone. Why would Professor Lin come to the school to give an open class?"

"It's hard to explain to someone like you. Stop dawdling. Professor Lin is coming soon. Get out of here!"

The two sides argued endlessly, and their voices became louder and louder, attracting the attention of the students around them.

When the principal saw that someone was causing trouble during the open class, he felt nervous and was about to step forward to stop it, but at this moment, Lin Qizhen walked in.

In an instant, the classroom fell silent, and everyone's eyes were focused on Lin Qizhen.

Professor Lin Qizhen was wearing a neat suit, his gray hair was combed meticulously, and his eyes revealed a gleam of wisdom.

He raised the corners of his mouth slightly, and when his eyes swept over Nan Qiao, a kind smile appeared on his face, instantly easing the tense atmosphere a lot.

Everyone thought that Lin Qizhen would help Lan Xuxue. After all, in their opinion, Lan Xuxue had always claimed that it was Professor Lin who was invited by them.

Several girls couldn't wait to start complaining, saying in unison, "Professor Lin, look, this student has taken Lan Xuxue's seat and won't give it up. That's too much."

"Xiaoxue took great pains to invite you here, she should be allowed to sit in the best seat."

"Yes, Professor Lin, you have to make the decision for Xiaoxue."

Lan Xuxue raised her chin slightly and smiled complacently, as if she was sure of victory.

However, when she met Lin Qizheng's eyes, she immediately became well-behaved and sensible, and called out to Lin Qizheng sweetly, "Professor Lin."

"I'm really surprised that you can come to No. 1 High School. Thank you for coming to No. 1 High School to give us an open class today."

Lan Xuxue seemed to be very familiar with Lin Qizhen and started talking naturally.

In the eyes of others, her few words made everyone think that Lin Qi was invited by her and came to do her a favor.

Suddenly, he sighed, "It seems that Professor Lin was really invited by Lan Xuxue."

"The Lan family is truly remarkable. They even managed to invite Professor Lin."

……

However, Lin Qizhen's expression was very calm. His eyes slowly swept over everyone and finally fell on Nan Qiao.

He nodded slightly as a greeting.

Then he said, "I'm not invited by anyone to give a lecture at No. 1 High School. Seating should be arranged on a first-come, first-served basis. There's no such thing as one person occupying another's seat. Everyone should just focus on the class."

After saying that, he walked up to the podium without even looking at Lan Xuxue, opened his laptop and prepared to start the class.

Everyone was stunned, especially the girls who had been so arrogant just now.

What's going on? Wasn't Professor Lin invited by Lan Xuxue?

Several people were suddenly panicked and ran back to their seats, not daring to say another word.

Lan Xuxue's face turned pale instantly. She never expected that Lin Qizhen would be so disrespectful to her.

Wang Xiaoxuan covered her mouth and laughed, then squinted at Lan Xuxue and said sarcastically, "Who do some people think she is? Everyone has to give in to her and flatter her."

In the end, Lan Xuxue was like a little clown, and went to the last row in shame.

The open class officially began. Nan Qiao was fully focused, with a gleam of curiosity in his eyes.

Sometimes she leaned forward slightly, listening carefully to every word Professor Lin said, afraid of missing any key knowledge points; sometimes she lowered her head and took quick notes in her notebook, the tip of the pen sliding across the paper, making a rustling sound.

When Professor Lin asked the question, Nan Qiao's brain was working fast, actively thinking about the answer.

Professor Lin’s insights are very unique. Just a simple explanation of any knowledge point can make students feel like they have suddenly seen something new.

"Professor Lin is indeed worthy of being Professor Lin. If I could have Professor Lin's class every day, it would be difficult for me not to get a perfect score in math."

But the more they listened, the more something seemed wrong. Professor Lin did not explain his knowledge from the beginning, nor did he summarize and then focus on a few key points.

He was talking about the knowledge points of the first year of high school, and started from the middle.

Wang Xiaoxuan couldn't help but whisper to Nan Qiao, "Why do I feel like Professor Lin is giving a tutorial instead of a public lecture?"

"Cough." Nan Qiao couldn't help coughing, "Why do you feel that way?"

"It's so down-to-earth, and the knowledge points here seem to connect with the knowledge points from the last supplementary class."

Nan Qiao looked down at her notes and quickly turned the page to cover the notes she had taken yesterday.

She was a little puzzled. Was Wang Xiaoxuan cheating? She guessed so accurately!

Nan Qiao couldn't help but glance at Lin Qizhen on the stage, feeling nervous and afraid of being discovered. Professor Lin, Professor Lin, you should at least pretend to be more convincing.

Lin Qizheng's classes only lasted an hour each. When the time was up, he turned off the computer and said, "Okay, that's all for today's class. I'll cover the remaining arithmetic formulas in the next class."

Having said that, he seemed to realize that what he said was wrong and added, "If I still have the opportunity to continue to give you open classes."

Many people laughed at Lin Qizhen's humor.

Wang Xiaoxuan said with a hint of reluctance, "Oh, there are still arithmetic formulas to be explained. I really hope to continue to the next class."

Lin Qizhen finished his class, packed up his things and was about to leave.

At that moment, the principal rushed forward like a whirlwind, his face covered with a flattering smile, and said eagerly, "Professor Lin, your class was truly wonderful! Would you be so kind as to take a photo with us? It would be a great honor for our school."

Lin Qizhen slightly frowned his sword-like eyebrows, a hint of barely perceptible annoyance flashed in his eyes, and he responded coldly: "Sorry, Principal, I'm not used to taking pictures."

The smile on the principal's face froze for a moment, but he still wanted to continue persuading unwillingly.

Lin Qizhen didn't want to get entangled anymore. His deep eyes quickly scanned the crowd and instantly locked onto Nan Qiao in the crowd.

Without hesitation, he raised his hand and beckoned towards Nan Qiao, saying loudly, "Classmate, you were the most attentive listener in class just now. Come over and take a picture together."

Nan Qiao's face was full of astonishment, and she slowly walked to Lin Qizhen under the gaze of everyone.

Lin Qizheng raised the corners of his mouth slightly, revealing a kind smile, and then calmly said to the principal: "Let's start."

The principal opened his mouth and wanted to say something, but seeing Lin Qizhen's prepared expression, he didn't know what to say. He could only quickly ask the teacher next to him to take a picture, as if he was afraid that Lin Qizhen would go back on his word.
