Cataclysmic Era: I can unlock the tech tree

"What?!"

As Lü Yongchang finished speaking, Fang Xu's eyes widened slightly, and he exclaimed in surprise, "You can solve the problem of room-temperature superconducting materials?"

Fang Xu's reaction made Hong Qiming, who was standing to the side, frown.

"Room-temperature superconductivity... I remember our country should have this technology, right?"

"I even saw a report last time that an academician from the Chinese Academy of Sciences had made a breakthrough in room-temperature superconductivity!"

Fang Xu glanced at Hong Qiming with a hint of helplessness and said softly, "Minister Hong, you must be referring to the paper that Academician Hu Changping published in Nature a while ago, right?"

Hong Qiming's eyes lit up slightly, and he nodded repeatedly, saying, "Yes, yes, Academician Fang, you have a good memory! I was referring to Academician Hu Changping's paper!"

"What? Is that technology unusable?"

A bitter smile appeared in Fang Xu's eyes as he slowly shook his head.

"Although Academician Hu Changping's superconducting material achieved superconductivity at room temperature of 15 degrees Celsius, there are actually prerequisites."

"This was achieved under a pressure of 2670 billion Pa, which is about a million times the standard tire pressure!"

"Moreover, the material that Professor Hu Changping used to induce superconductivity in a diamond cavity was extremely small in quantity!"

"It even needs to be expressed in picoli!"

Seeing the look of doubt in Hong Qiming's eyes, Fang Xu quickly added, "A picoliter is a unit of measurement; one picoliter is approximately 10^-9 milliliters!"

Hong Qiming gasped sharply.

Now he understood completely.

Such stringent conditions, such limited materials...

Applying this technology to controlled nuclear fusion is simply a pipe dream!

Fang Xu swallowed hard and muttered to himself, "So far, I haven't heard of any country that has truly mastered this technology!"

Then, he took a deep breath, calmed himself down, and spoke again, his voice firm and resolute.

"True room-temperature superconducting materials need to achieve superconductivity at room temperature and pressure!"

"This is extremely difficult!"

Hong Qiming frowned.

When he first heard what Lü Yongchang said, he was even a little excited.

Lu Yongchang's nonchalant and assertive manner created a misconception for him.

That is, room-temperature superconducting technology is very simple!

But now, under Fang Xu's cold water, Hong Qiming's feverish mind gradually calmed down.

He turned to look at the composed Lü Yongchang in front of him, frowned, and asked, "Are you sure you can solve the problem of room-temperature superconducting materials?"

Lu Yongchang smiled slightly and nodded slowly but firmly.

Yes, room-temperature superconductivity technology is very difficult.

But in his previous life, this technology had already been mastered.

Moreover, the scientist who solved this problem for the Xia Kingdom was none other than Lü Yongchang himself!

After a moment of contemplation, he slowly said, "I need a standard carbon nanomaterials laboratory and a few assistants."

"If all goes well, give me a few days, and I can present the results to you!"

Fang Xu's eyes flickered slightly, clearly gleaning some hidden information from Lü Yongchang's words.

He stared at Lü Yongchang in astonishment, his voice rising an octave: "Are you sure carbon nanomaterials can achieve room-temperature superconductivity?!"

Lu Yongchang remained silent for a while, and from Fang Xu's curious eyes, he understood a message.

"How about... you watch me do it?"

Fang Xu: "...It's not entirely impossible."

Perhaps realizing he had revealed his intentions, a hint of embarrassment flashed in Fang Xu's eyes: "Ahem, it's not that I'm curious, I'm just worried that you're not familiar with how to use those experimental equipment..."

Lü Yongchang: "..."

……

Sandaokou University Carbon Nanomaterials Laboratory.

"Lu...Lu, take a look, can this laboratory meet your requirements?"

As he spoke, a hint of awkwardness appeared in Fang Xu's eyes.

As an academician, this was his first time mentoring a second-year undergraduate student!

The thought that he might become this undergraduate's assistant in the future made Fang Xu feel even more awkward.

No, we need to think of a way.

How about... we ask Old Jiang to get this kid a professorship?

It sounds better to say it that way.

At least no one would say that he, a dignified academician, was working under an undergraduate!

Fang Xu thought about it more and more and felt it was reliable, so he immediately approved the proposal in his mind.

"Achoo!"

Lu Yongchang, who was walking in front, suddenly sneezed.

He turned his head with a suspicious look and glanced at Fang Xu behind him.

I had a feeling of chill coming from behind me just now.

Could it be that Fang Xu is cursing at me?

Faced with Lü Yongchang's meaningful gaze, Fang Xu's expression suddenly froze!

Then, he forced a smile and said, "Student Lü, take a look and see if this lab is suitable. If it's not, we might have to go somewhere further away to find a better lab."

Lu Yongchang turned around thoughtfully and looked at the instruments in the laboratory.

After looking him over, a hint of disdain appeared in Lü Yongchang's eyes.

That's it?

In his previous life, he wouldn't have even given a second glance to a laboratory with this kind of setup!

but now……

Hey!

Just make do with it!

If Tony Stark could build the Mark I with his bare hands in a cave, he could certainly create room-temperature superconducting materials in this "outdated" laboratory!

"It's barely acceptable."

Lu Yongchang responded to Fang Xu's question with a calm expression.

As for Fang Xu, his eyes widened instantly upon hearing Lü Yongchang's words!

"reluctantly?!"

"Did you know this is the best carbon nanomaterials lab at Sandaokou University?!"

"I'm not bragging, but this lab, even in China right now, would easily rank in the top ten!"

Lu Yongchang glanced speechlessly at the indignant Fang Xu beside him: "Didn't you just say that if it didn't work out, we could find a better lab?"

Fang Xu: "..."

"I... I was just being modest. Do you understand what modesty is?!"

Lu Yongchang raised his hands and said softly in a tone as if coaxing a child, "Okay, okay... I take back what I said. This laboratory is very advanced and very good."

"Is this okay now?"

Fang Xu: "..."

He swore he had never been so speechless in his life!

He followed Fang Xu silently.

He wanted to see for himself just how capable this second-year undergraduate student really was!

Surely you can't not even recognize the names of the experimental instruments?

Thinking of this, a smile flashed in Fang Xu's eyes.

It's worth noting that many of the experimental equipment in this laboratory in Sandaokou has just been upgraded!

Let alone Lü Yongchang, an undergraduate student, even he was a bit unfamiliar with using it!
