Lü Yongchang slightly furrowed his brows.
As he remembered, he seemed to have lost his temper because of this sound once.
After all, during intense scientific research tasks, the rhythmic clicking sound of the ball - point pen ratchet was simply a nerve - racking thing!
He looked in the direction where the sound came from.
Uh...
The girl beside him was holding a pink - colored ball - point pen, frowning at an exercise book in front of her, and unconsciously pressing the pen cap with her right hand.
A hint of helplessness appeared in Lü Yongchang's eyes.
He remembered now.
In his previous life, it was because of Su Yutong's this habit that he rarely lost his temper during a scientific research task.
From that time on, Su Yutong got rid of this habit.
But now... obviously, she hadn't corrected this bad habit yet.
Lü Yongchang knew very well that if she didn't solve the problem in front of her quickly, probably... this clicking sound would accompany him all day!
Helplessly, Lü Yongchang took a deep breath, turned his head, and asked in a low voice, "Classmate, did you encounter any difficult problems?"
Su Yutong was startled, and the movement of pressing the pen cap in her hand suddenly stopped.
Seeing that it was Lü Yongchang asking, a flash of vigilance instantly appeared in her eyes.
Could it be that... this boy finally summoned up the courage to strike up a conversation with her?
At that moment, Su Yutong had already thought of at least three ways to reject him in her mind!
"I said... are you in some trouble?"
Lü Yongchang noticed the vigilant look in Su Yutong's eyes. He pointed at the exercise book in front of her and then at the ball - point pen in her hand with an expression of helplessness, "This... the sound is a bit disturbing."
"..."
The two looked at each other in silence.
Gradually, an embarrassed look appeared on Su Yutong's face.
A bit of shyness rose on both sides of her cheeks. She nodded gently and said, "Sorry... I disturbed you. I'll try to control this habit!"
Lü Yongchang said reluctantly and with a look of helplessness, "Show me the question."
"Maybe I can help you solve it."
Come on, trying to control?
He didn't want to be disturbed while reading the research paper!
Sure enough, women were just something that would slow down his research progress!
"Really?!"
A look of surprise appeared in Su Yutong's eyes. Then she hastily put the exercise book in front of Lü Yongchang.
And then, she looked at Lü Yongchang expectantly.
Looking at Su Yutong like this, an image suddenly emerged in Lü Yongchang's heart.
A hamster!
At this moment, Su Yutong was just like a big hamster, holding a sunflower seed in her hand and staring straight at him.
Lü Yongchang sighed again and turned his head to look at the exercise book in front of him.
It was an extremely basic limit - finding question type.
"You know how to use L'Hopital's rule, right? Just apply it to this question. It's very simple."
Saying that, Lü Yongchang was about to return the exercise book to Su Yutong.
But obviously, he overestimated Su Yutong at this time.
Seeing Su Yutong looking around in a daze with the pen in her hand, Lü Yongchang sighed again.
"Forget it. I'll write out the steps for you."
Saying that, he picked up the fountain pen in his hand, quickly wrote down the standard problem - solving steps on an A4 paper in front of him, and then handed it to Su Yutong along with the exercise book.
Compared with a ball - point pen, Lü Yongchang was more used to a fountain pen.
He liked the swishing sound when the fountain pen wrote on the paper.
"Th - thank you."
Su Yutong subconsciously took the exercise book and softly said thank you.
Looking at the delicate fountain - pen writing on the A4 paper, Su Yutong subconsciously glanced at the somewhat round writing on her draft paper. A hint of embarrassment and curiosity appeared in her eyes.
"May I ask your name? I'm Su Yutong from the Department of Applied Physics."
Lü Yongchang didn't turn his head and impatiently reported his name, "Lü Yongchang."
Just now, because of solving the problem and talking, he had already wasted nearly five minutes!
Sure enough!
Women were nothing but a stumbling block on his research path!
While sighing in his heart, Lü Yongchang shifted his gaze to another research paper.
"An Analysis of the Influencing Factors of Sonoluminescence Phenomenon"
At this moment, he had completely forgotten the feeling of guilt towards Su Yutong in his heart not long ago.
Of course, even if he remembered, he had plenty of reasons to convince himself.
Reasons like it's not appropriate to talk about love at a time when humanity's survival is at stake were everywhere!
What's more, Su Yutong at this time was not the Su Yutong in his previous life. She didn't have any feelings for him at all!
As for Su Yutong, after being rebuffed by Lü Yongchang, she turned around with an embarrassed look and continued to study the exercise book in front of her.
...
"Ding dong."
A message notification sound came from the mobile phone beside him, interrupting Lü Yongchang's action of flipping through the research paper.
He slightly raised his head and looked at the mobile phone placed on the table.
A piece of news appeared on the locked screen.
"Xia Country Announces Its Withdrawal from the ITER Plan!"
"Shocking! The Real Reason Behind Xia Country's Withdrawal from the ITER Plan Is..."
"Morally Degenerate! How Could a Researcher Do Such a Thing!"
Lü Yongchang's heart skipped a beat.
He remembered.
At this time, Xia Country was targeted in the ITER Plan. Helplessly, it had to take the initiative to withdraw from the ITER Plan.
This also planted hidden dangers for the future!
The time when Xia Country successfully developed the controlled nuclear fusion technology was more than two years later than that of Western countries!
Therefore, Xia Country didn't have much say in the final United Earth Alliance.
It was not until Lü Yongchang successfully became the chief scientist of the United Earth Alliance Academy of Sciences that the status of Xia Country gradually improved!
Only then did Lü Yongchang know that behind Xia Country's active withdrawal from the ITER Plan, there was a series of frame - ups!
"Damn it..."
Lü Yongchang looked at the mobile phone on the table with cold eyes.
As a citizen of Xia Country, he absolutely would not allow such a thing to happen again!
So what if it withdrew from the ITER!
He would make all the countries that targeted Xia Country know that in the future world, Xia Country would have the final say!
Lü Yongchang quickly tidied up the things on the table, stood up, and prepared to leave.
He couldn't wait any longer!
He needed to take the initiative to ask Professor Guan Hualiang about the review result!
"Eh... Are you leaving?"
Su Yutong's unique cold voice came from the side.
Lü Yongchang gently nodded, didn't say much, and left on his own.
"Tsk... So aloof!"
Su Yutong looked at Lü Yongchang's back, pouted, "Deserves to be single for a lifetime!"
The next moment, she was attracted by the A4 paper left on the table by Lü Yongchang.
Looking at the dense formulas and symbols on it, she was so surprised that she reached out to cover her slightly opened lips.
This... She thought this boy was at the same grade as her!
Now it seemed that he was probably a postgraduate or a doctoral student, a big shot!
A hint of different colors flickered in Su Yutong's eyes, and the seeds of curiosity gradually took root in her heart.
