Chapter 691: A sudden shock Two red clouds appeared on Liu Xiaohua’s cheeks and spread all the way behind her ears.
She lowered her head, and it felt like a sugar firework exploded in her heart, sweet and warm.
She has never been given such beautiful clothes since she was a child.
"This...this must cost a lot of money, right?" She murmured softly, feeling both happy and uneasy about the expense. "It's too expensive...I can't accept it..."
"It's not expensive, not expensive!" Zhao Rui waved his hands quickly. He almost wanted to tell the truth, but he quickly swallowed the words back and said, "You...it's okay as long as it looks good on you. Go try it on and see if it fits you."
The eagerness and sincerity of the young man dispelled Liu Xiaohua's last bit of hesitation.
She pursed her lips, suppressing the smile that was about to overflow, and nodded gently: "...Thank you."
Liu Xiaohua stood up and said, "Wait for me, I'll go change in the house."
There are no customers yet, so the restaurant is not very busy.
Liu Xiaohua went to the back room to change her clothes.
After she changed her clothes and came out, she walked in front of Zhao Rui.
"Does it look good?" she asked shyly in a low voice, tugging at the hem of her sweater with her fingers, looking at Zhao Rui with sparkling eyes.
Zhao Rui was stunned by what he saw. He felt that the girl in front of him was like a flower that was suddenly blossomed by the spring breeze, shining brightly.
My heart was pounding, and I could only nod my head foolishly: "It looks good, it looks really good, just like... just like it was made especially for you!"
Liu Xiaohua felt even more embarrassed by the straightforward compliment. She lowered her head, but the corners of her mouth couldn't help but rise high.
She picked up the off-white scarf again and wrapped it around her neck. The furry touch was particularly comfortable.
Just then, Ma Hongxia came in from outside. Seeing her daughter wearing new clothes and with a rosy face, she was stunned at first, then she looked at Zhao Rui who was grinning foolishly beside her, and immediately understood what was going on.
She also showed a relieved smile on her face and deliberately joked, "Hey, where did this pretty girl come from? This new sweater is so smart! Did Xiao Zhao buy it for you?"
Liu Xiaohua called out "Mom!" coquettishly, her face turning even redder, but she was reluctant to take off her new clothes.
Zhao Rui also laughed embarrassedly.
…
The next day, in the evening, Lu Qingyang followed the location told by Professor Chen's teaching assistant and found a small conference room in the slightly old red brick building of the Department of Mathematics.
The door was ajar, and from inside came the murmur of discussion and the rustling of chalk across the blackboard.
놛 gently pushed open the door, and the scene inside made 놛 pause slightly.
The conference room was not big, with a long table in the middle, and eight students sitting around it. They all looked older than me, at least juniors, seniors, or even graduate students.
In front of each of them was a thick stack of notes and their expressions were focused and devoted.
Professor Chen was sitting in the main seat, listening to a boy wearing glasses explaining the corollary of a theorem, nodding slightly occasionally.
The blackboard was already covered with densely packed symbols and formulas, the complexity of which far exceeded what Lu Qingyang had seen in the basic physics courses.
The entrance of 놛 broke the original 놋 atmosphere.
Almost all eyes were instantly cast on the strange, overly young face at the door.
There was curiosity and scrutiny in his eyes, but more of it was a kind of alienation and subtle contempt that belonged to the circle of top students.
A graduate student who looked like the leader adjusted his glasses and asked, "Student, have you come to the wrong place? This is a mathematics seminar."
The tone was polite, but with obvious doubt.
Lu Qingyang looked calm and nodded slightly. "Excuse me, is this the seminar hosted by Professor Chen? I'm Lu Qingyang, a freshman in the Department of Physics, and I'm here at Professor Chen's invitation."
"Physics Department?"
"A freshman?"
A few very low exclamations and whispers were heard.
The crowd's gazes became more inquiring, even carrying a bit of undisguised suspicion.
Professor Chen's seminar is notoriously difficult to enter in the Department of Mathematics. All those who can enter are top senior students who have been carefully selected and have demonstrated strong talent and a solid foundation in mathematics.
A freshman majoring in physics? That sounds like a fantasy.
Professor Chen spoke at this time, his voice steady and calm: "Student Lu Qingyang is here, please find an empty seat. We are discussing some basic work in algebraic geometry."
There was no further introduction, and Lu Qingyang was directly integrated.
But this calm attitude only confirmed some people's speculation that the professor might just be doing it out of courtesy.
Lu Qingyang followed his instructions and found an empty seat at the end of the long table and sat down. He ignored the questioning looks around him and his attention was quickly drawn to the content being deduced on the blackboard.
That was indeed quite in-depth content, involving the preliminary concepts of fiber bundles in homology theory, and even for me, it required concentration to follow.
The discussion continues.
The graduate student who spoke earlier continued to elaborate, occasionally raising questions or adding to the discussion.
Lu Qing listened quietly without interrupting.
After a while, the discussion progressed to the proof of a key lemma, and the derivation seemed to have reached an impasse.
The graduate student who was speaking was stuck. He tried several methods but couldn't make his point, and his brows were furrowed.
Qi Dong also fell into deep thought, and the meeting room fell silent for a moment.
"Here," a cold voice suddenly rang out from the end of the long table, breaking the silence, "perhaps we could consider using spectral sequence tools. While it might be overkill, it would allow us to more clearly see the recurrence relationships between the cohomology groups at each level, thus bypassing this obstacle."
Everyone looked up in astonishment, looking at the source of the voice. It was the freshman from the Physics Department who had just come in and had been ignored by everyone.
Spectral sequences? Layers? These concepts are advanced tools that are only encountered in depth in advanced mathematics departments or even graduate schools.
How could a freshman in physics know this, and even propose it so casually as a solution?
The graduate student who had spoken earlier was stunned for a moment, then a hint of displeasure appeared on his face, feeling that the other party was deliberately showing off and trying to attract attention. He pushed his glasses up:
"Hey... Mr. Lu Qingyang? Spectral sequences aren't fundamental, and introducing them in this problem is too complicated. Perhaps we should look for a more elementary method..."
"It's complex, but effective and profound. Furthermore, it reveals the deeper mathematical structure of the problem, not just the immediate solution. If one simply wants to complete the proof, there are certainly more circuitous approaches. But isn't the point of the seminar to explore more elegant and qualitative solutions?"
As he spoke, he stood up naturally, walked to the blackboard and picked up a piece of chalk.
He didn't even erase the original blackboard writing, but just wrote a series of symbols fluently in the blank space next to it, constructing a concise spectrum sequence relationship diagram, and clearly pointed out how to use it to solve the current proof dilemma.
놛's movements are smooth and flowing, and his use of symbols and concepts is as natural as breathing. This is definitely not a level that can be faked at the last minute.
The entire conference room fell silent.
Professor Chen looked at the derivation on the blackboard, his eyes shining with surprise, and the corners of his mouth couldn't help but rise.
You were right! This young man's mathematical intuition and knowledge far exceeded your expectations!
