"Let's invite Luo Qingchen to answer this question for me." The math teacher pushed up his glasses and raised his eyebrows at Luo Qingchen.
Lu Qiufan, who was sitting at the same table as her, subconsciously moved her textbook towards her, but was pushed back by her.
All the students thought that she would go up on stage to calculate, but who would have thought …
"A = ln2."
"Hiss —" She heard one or two gasps of cold air.
After all, she didn't have a textbook or workbook, so she could only calculate on the spot to be able to answer so quickly.
"Hmph! Isn't it just memorizing the answer? Do you really think you're a math genius? "Ye Sitian pursed her lips, and her disdainful voice rang out in the quiet classroom.
"Then why don't you memorize one for me to see?"
"What a joke. You're talking as if you can answer it." Ye Sitian didn't forget to give the math teacher a look as she sneered.
The math teacher immediately understood. He picked up the chalk and wrote a question on the blackboard.
It was a question that was definitely beyond the ability of a first-year student. It was impossible for this student called Luo Qingchen to solve it.
"Then, let's invite Luo Qingchen …"
"Let point M (x, y, z) be on the curve. Then the distance from point M to the xOy plane is: z." She directly interrupted the math teacher and ignored all the calculations. "So when M is (1,1,1), there is a minimum distance of z = 1. So when M is (-5, -5, 5), there is a maximum distance of z = 5."
"Hiss —"
"What's going on?"
"Are you for real?"
All the students in the class were in disbelief. They had naturally seen many students with good grades. For example, the cold and aloof Mu Nanxi and her deskmate, the bookworm Chubby.
They were all from ordinary families and had entered Alice Academy with their grades.
Their grades were also very good, but they had never … said the answer so quickly.
This was simply … unbelievable …
The math teacher looked at the answer nervously, and cold sweat dripped down.
Luo Qing Chen had indeed given the correct answer and it wasn't wrong at all.
"Teacher, are you done reading? Could it be that someone made up the answers?" Ye Sitian frowned. Her tone was clearly very unpleasant, and she looked indignant.
"The answer is correct …" The math teacher wiped the sweat from his forehead and coughed lightly. "But Luo Qingchen should have already done this question!"
"Would you believe me if I said I didn't?" Luo Qingchen didn't wait for the math teacher to speak and directly sat down.
Ye Sitian gritted her teeth. She wanted to say something, but she couldn't find a reason. She could only force her face to flush with anger.
Less than three seconds after she sat down, the person behind her tapped her shoulder with a black pen and said, "Hey, have we met before?"
Stunned, she turned her head abruptly and bumped into Yu Qianjin's dark eyes. Fragments of sunlight shone on his almost perfect side profile. He narrowed his eyes and looked into her eyes.
Luo Qing Chen felt her breathing stop and her heart was beating like a little deer running around in her stomach.
Perhaps it was because the "cannon fodder halo" that had been dormant for a long time was still lingering above her head. When Yu Qianjin suddenly spoke to her, she was so nervous that her palms couldn't help but sweat.
"I …" Luo Qingchen wanted to say something, but she was interrupted by a girl who walked in from the back door.
"Young Master Jin, I bought you mineral water. It's not ice!" He Qingqing sat in the empty seat beside him and said, "You have a weak stomach. Ice water isn't suitable in this weather."
At this moment, Luo Qingchen felt like a bottle of ice water had been poured over her head.
