"Your turn!" Tong Chenxi put down the chalk and walked to the side to wait for Tang Xiu's answer.
Tang Xiu strode up to the podium and looked at the question. A disdainful smile appeared on his face,
"You have the nerve to take out these kind of classroom practice questions?”
With that, he waved his hand and the answer was written out like flowing water.
"Solution: For a lattice with a double spiral axis, if there are the same atoms in (x, y, z) and (x 1/2, -y, -z), then…"
" When h is an odd number, then F is 0 when cosh =-1, so there is extinction.”
After he finished writing a series of calculations, Tang Xiu patted the chalk dust on his hands and lightly said,"It's not difficult at all."
Tong Chenxi was so angry that her cheeks puffed up. She pouted and said,"Then come up with a question. Let me see what the normal difficulty is!”
"Then I'll do as you say!"
Tang Xiu pondered for a while and then raised his hand to write in the middle of the blackboard,
"Let (X, d) be a complete space, T:X→X. If there is a non-negative number n such that Tn is a contraction map, then the map T has a unique fixed point. Prove that this conclusion is a true extension of the contraction map theorem.”
After putting down the chalk, Tang Xiu took a step back and smilingly said,"Please!"
The scene on the podium attracted the attention of the students discussing below. They turned their heads and looked over curiously, whispering,
"Isn't that Sister Chenxi? Why are you free to come to our discussion today?”
"Just now, I heard that he was competing with the new student beside him.”
"Uh, the difficulty of this question is not bad. I can barely calculate it.”
"This new student's standard is not bad, to actually be able to answer it so quickly. It seems that he has learned the relevant courses in university in advance.”
"He has started to set the questions and asked me to take a look at the knowledge reserves of the freshmen.”
“emmmm……”
"Uh…"
"Ahem…"
The students looked at the blackboard in confusion for a long time. Then, they turned around and spread out the textbooks and papers on the desk to continue their discussion.
What was written here?
He could understand every Chinese character and letter separately, but why couldn't he recognize them at all when they were connected?
We're top students, how can there be questions that we can't understand? Could it be that I'm actually a bad student?
Illusion, it must be an illusion!
Tong Chenxi bit her lip and looked at the question on the blackboard with a frown. She raised and put down the chalk in her small hand. After hesitating for a long time, she finally began to calculate.
Su Muxi's eyes were full of circles. She could understand Chen Xi's questions, but she couldn't understand Tang Xiu's questions.
Was there a fake promotion? I only know how to do marketing!
Am I still human? Why do I feel like I'm a fake top student?
Tong Chenxi wrote a few lines of calculations in a stumbling manner. Then, she was stuck in a process and could not continue.
Three minutes passed. No matter how hard she tried to calculate, she could not fill in this step.
Looking at the other party's big eyes that were about to cry, Tang Xiu smilingly said,"Sister Tong, how is it? If you really can't do it, don't force yourself. I can give you special tutoring!”
Tong Chenxi rolled her eyes at him and continued to write.
After writing a few lines, Tang Xiu stopped him."Stop writing. From this point on, the theory used is wrong. It will only get further and further away from the correct answer!”
Upon hearing this, Tong Chenxi's last bit of arrogance was completely crushed. She put down the chalk dejectedly and lowered her head in silence.
Su Muxi quickly stepped forward to smooth things over.""It's okay. Senior, you're a chemistry major. It's normal for him to not know how to test you with math questions!”
"But he solved my chemistry question too!”
"Uh…"
Su Muxi was speechless. I gave you a way out, why didn't you? Why did you have to stab yourself in the back?
However, she was still young after all, so her anger came and went quickly. After a while, Tong Chenxi ran to Tang Xiu and curiously asked,"How should I solve this problem?"
"Hehe." "Call me Big Brother," said Tang Xiu with a smile.”
When Tong Chenxi heard this, her face immediately turned red. She had been a child prodigy since she was young. Only others looked up to her. No one had ever made her bow down to them.
However, this time, he lost miserably.
At the thought of this, she lowered her head and opened her mouth shyly. She muttered softly,"Big brother!"
"Hey!" Tang Xiu responded with satisfaction. He turned his head and saw Su Muxi. He rolled his eyes and leaned over,
"Since you call Chenxi senior sister, shouldn't you call me big brother instead of Chenxi calling me big brother?”
Su Muxi rolled her eyes. My real age is one year older than yours.”
"Who said that? You clearly look only eighteen years old. You're at your most beautiful!”
Su Muxi blushed at the sudden sweet talk. No one had ever praised her so bluntly before, and she was at a loss for words.
The students below raised their heads with resentful expressions.
This is too much. It's one thing for her to embarrass us with the questions, but she actually showed off her love and fed us dog food in front of us.
We are top students, we have dignity!
Feeling the resentment of the audience, Tang Xiu turned his head and smilingly said,"Students, if anyone can answer this question, please step forward. Let's discuss it together!”
Crash!
Everyone immediately lowered their heads and looked at the book in their hands with a thoughtful expression, as if they were completely immersed in the ocean of learning.
As for dignity? Wait until I know how to solve this problem.
