Age of Cataclysm: I can light up the technology tree

Lv Yongchang frowned slightly.

In his memory, he seemed to have lost his temper once because of this sound.

After all, in the tense scientific research tasks, the rhythmic clicking sound of the ballpoint pen ratchet is simply a life-threatening artifact!

He looked in the direction where the sound came from.

Uh...

The girl next to him was holding a pink ballpoint pen in her hand, frowning and looking at a workbook in front of her, and her right hand was unconsciously pressing the ballpoint pen head.

Lv Yongchang's eyes showed a bit of helplessness.

He remembered.

In his previous life, it was because of Su Yutong's habit that he rarely lost his temper during a scientific research task.

From then on, Su Yutong changed this habit.

But now... obviously, she has not corrected this bad habit.

Lv Yongchang knew very well that if she did not quickly solve the problem in front of her, it was estimated that... this clicking sound would accompany him all day!

Helplessly, Lv Yongchang took a deep breath, turned his head, and whispered: "Classmate, have you encountered any difficulties?"

Su Yutong was startled, and the action of pressing the ballpoint pen in her hand suddenly stopped.

Seeing that it was Lv Yongchang who asked the question, a trace of vigilance flashed in her eyes.

Could it be that... this boy finally mustered up the courage to approach her?

At that moment, Su Yutong had even thought of at least three ways to refuse!

"I said... have you encountered any difficulties?"

Lv Yongchang noticed the vigilance in Su Yutong's eyes, and pointed helplessly at the exercise book in front of her, and then pointed at the ballpoint pen in her hand: "This... the sound is a bit noisy."

"..."

The two looked at each other in silence.

Gradually, an embarrassed look appeared on Su Yutong's face.

She blushed a little on both sides of her cheeks, nodded gently and said: "Sorry... I disturbed you, I will try to restrain this habit!"

Lv Yongchang said helplessly and reluctantly: "Show me the question."

"Maybe, I can help you solve it."

Joke, try to restrain yourself?

He didn't want to be disturbed when reading a paper!

Sure enough, women will only slow down the progress of his research!

"Really?!"

Su Yutong's eyes showed a touch of surprise, and then he hurriedly put the exercise book in front of him in front of Lu Yongchang.

Then, he looked at Lu Yongchang expectantly.

Looking at Su Yutong's appearance, Lu Yongchang suddenly had an image in his heart.

Hamster!

At this time, Su Yutong was just like a large hamster, holding a melon seed in his hand, staring at him blankly.

Lv Yongchang sighed again and turned his head to look at the exercise book in front of him.

Extremely basic limit problem type

"You know how to use L'Hôpital's rule, right? Just solve this problem once, it's very simple."

As he said this, Lv Yongchang was about to return the exercise book to Su Yutong.

But obviously, he overestimated Su Yutong at this moment.

Seeing Su Yutong looking around with a confused look, Lv Yongchang sighed again.

"Forget it, I'll write out the steps for you."

As he said this, he picked up the pen in his hand and quickly wrote down the standard problem-solving steps on an A4 paper in front of him, and then handed it to Su Yutong together with the exercise book.

Compared with ballpoint pens, Lv Yongchang is more accustomed to fountain pens.

He likes the swish sound of fountain pens writing on paper.

"Thank you... thank you."

Su Yutong subconsciously took the exercise book and said thank you softly.

Looking at the beautiful fountain pen handwriting on the A4 paper, Su Yutong subconsciously glanced at the somewhat round handwriting on his draft paper, and a trace of embarrassment and curiosity appeared in his eyes.

"Can I ask your name? I'm Su Yutong from the Department of Applied Physics."

Lv Yongchang didn't turn his head, and gave his name impatiently: "Lv Yongchang."

Just now, because of solving problems and talking, he has wasted nearly five minutes!

Sure enough!

Women will only become stumbling blocks on his research path!

While sighing in his heart, Lv Yongchang turned his eyes to another paper.

"A Brief Analysis of the Influencing Factors of Sonoluminescence Phenomenon"

At this time, he had completely forgotten the guilt he felt towards Su Yutong not long ago.

Of course, even if he recalled it, he had sufficient reasons to convince himself.

There are a lot of reasons like it's inappropriate to talk about love at the critical moment of human survival!

What's more, Su Yutong at this time is not Su Yutong in the previous life. She doesn't feel good about herself at all!

As for Su Yutong, after being defeated by Lv Yongchang, she turned around with embarrassment and continued to study the exercise book in front of her.

…

“Ding Dong.”

A message alert sounded from the phone beside him, interrupting Lv Yongchang’s action of flipping through the paper.

He raised his head slightly and looked at the phone on the table.

A piece of news appeared on the lock screen.

“Xia Guo announced that it would withdraw from the ITER project!”

“Shocked, the reason behind Xia Guo’s withdrawal from the ITER project was…”

“Moral corruption! How could researchers do such a thing! ”

Lv Yongchang’s heart skipped a beat.

He remembered.

At this time, Xia Guo was severely targeted in the ITER project, and had no choice but to withdraw from the ITER project.

This also laid hidden dangers for the future!

The time when Xia Guo successfully developed controlled nuclear fusion technology was more than two years later than that of Western countries!

Therefore, Xia Guo did not have much say in the last Human Union.

It was not until Lv Yongchang successfully became the chief scientist of the Human Union Academy of Sciences that Xia Guo's status began to gradually improve!

It was not until then that Lv Yongchang knew that behind Xia Guo's voluntary withdrawal from the ITER project was a series of frame-ups!

"Damn..."

Lv Yongchang looked at the mobile phone on the table with cold eyes.

As a Xia Guo, he would never allow such a thing to happen again!

So what if he withdrew from ITER!

He wanted to let all the countries targeting Xia Guo know that the future world would be decided by Xia Guo!

Lv Yongchang quickly packed up the things on the table and stood up to leave.

He couldn't wait!

He needed to take the initiative to ask Professor Guan Hualiang about the results of the review!

"Huh... Are you leaving?"

Su Yutong's unique cold voice came from the side.

Lv Yongchang nodded lightly, without saying much, and left on his own.

"Tsk... so cool!"

Su Yutong looked at Lv Yongchang's back and curled her lips: "You deserve to be single for life!"

The next moment, she was attracted by the A4 paper left on the table by Lv Yongchang.

Looking at the densely packed formulas and symbols on it, she covered her slightly open lips with her hand in surprise.

This... She thought that this boy was in the same grade as her!

Now it seems that he is probably a big guy who is studying for a master's degree or a doctorate!

Su Yutong's eyes flashed with a bit of strange colors, and the seeds of curiosity gradually took root in her heart.
