I accidentally got a two-way foil in my second level civilization

Early the next morning, Fang Xu pushed open the door of the laboratory with a pair of panda eyes.

Looking at the busy researchers in the laboratory, a hint of confusion appeared in Fang Xu's eyes.

Where was Lü Yongchang?

He quickly grabbed a passing researcher and asked, "Mr. Lü... Where is Lü Yongchang?"

A look of surprise flashed in the researcher's eyes, and then he pointed to the depths of the laboratory.

"Professor Lü arrived long ago. When we came, he was already busy in the laboratory!"

Somehow, Lü Yongchang had become "Professor Lü" in the mouths of these researchers.

Fang Xu didn't bother to correct their address.

After all, after seeing Lü Yongchang's skilled and confident scientific research methods, not only these researchers, but even Fang Xu felt a bit of admiration from the bottom of his heart!

If he didn't know Lü Yongchang's identity, he would probably mistake Lü Yongchang for a senior professor!

Putting aside his thoughts, Fang Xu quickly turned his head to look at the wall clock.

It was 6:45.

He clicked his tongue secretly.

Sure enough, everyone's success didn't come by accident.

Fang Xu sighed in his heart and quickened his pace towards the depths of the laboratory.

...

Perhaps hearing the approaching footsteps, Lü Yongchang shifted his gaze from the device in front of the experimental bench.

Seeing the dark circles under Fang Xu's eyes, he was taken aback.

"What happened to you?"

Fang Xu waved his hand with a smile and said indifferently, "Bah! It's nothing! I just couldn't sleep last night!"

"Why don't you go and take a rest?" Lü Yongchang said with concern, "Anyway, there's not much to do today. We just need to test the superconducting properties of the carbon nanotubes."

A flash of excitement appeared in Fang Xu's eyes, and he directly burst out a swear word, "Rest my ass! I got these dark circles because of this. You still want me to rest?!"

"Where's the wire? Let me take a look!"

Looking at the excited Academician Fang, Lü Yongchang couldn't help but laugh.

He stepped aside and revealed the device on the experimental bench.

It was a glass cover with a diameter of 30 centimeters.

Fang Xu quickly took two steps forward and came to the side of the glass cover.

Through the glass cover, he clearly saw a black wire about ten centimeters long connected to two metal probes.

The wire was very thin.

Judging by the naked eye, it was almost as thin as a hair.

Fang Xu stretched out his hand, bent his fingers, and gently tapped the glass cover, "Is it... a vacuum inside?"

Lü Yongchang shook his head and denied it, "Of course not. It's just a small clean room for now. You don't want some dust to affect the experimental results, do you?"

But soon, he added again, "To be precise, it's not a vacuum environment yet."

As he spoke, Lü Yongchang pointed to the vacuum - pumping instrument beside him.

Fang Xu's eyebrows slightly raised.

This sentence carried a lot of information.

"Does that mean... this material can also achieve superconductivity in a vacuum environment?!"

Lü Yongchang reached out and took an A4 paper filled with words from the experimental table and handed it to Fang Xu, "According to my calculations, the superconducting wire made of carbon nanotubes has extremely stable properties. The normal operating temperature range is between - 50°C and 80°C."

Fang Xu's eyes lit up, and he quickly asked, "What about the air pressure?"

"Within two standard atmospheres."

"Hiss!"

Hearing Lü Yongchang's answer, Fang Xu gasped.

Good heavens!

If it was really as Lü Yongchang calculated, this superconducting wire made of carbon nanotubes could be applied to almost any corner of the earth!

Even in the deep sea with extremely high pressure, only an anti - pressure pipeline needed to be installed!

This also meant that Xiaguo's power industry was about to undergo earth - shattering changes!

"Yongchang... Do you know what you've done?"

Thinking about a series of future changes, Fang Xu stood there dumbfounded, muttering to himself.

A smile appeared at the corner of Lü Yongchang's eyes, but he didn't say anything.

He naturally knew what this wire meant!

Although these technologies were a bit advanced for Xiaguo now, they were still far from enough to deal with future disasters!

After admiring the carbon nanotube wire on the experimental bench for a while, Fang Xu said with a solemn expression, "Let's start the test!"

...

Learning that the first test of the room - temperature superconducting coil was about to begin, all the researchers in the laboratory put down their unfinished scientific research tasks and gathered around Lü Yongchang.

This was an opportunity to witness history!

No one would want to miss such a chance!

Lü Yongchang swallowed slightly, and carefully reached out to connect the metal probes at both ends of the wire to the testing instrument.

Although he had great confidence in the material he made, but...

In materials science, who could say for sure?

Maybe there was an accident during the manufacturing process, causing the inclination angle of the carbon nanotubes to change by 1°, or for some other reason...

It could be said that as long as there was the slightest mistake, the manufacturing of this room - temperature superconducting material would be a failure!

While thinking randomly in his mind, he turned on the switch of the testing instrument.

Power on!

A number appeared on the screen of the testing instrument.

Resistance value: 0 Ω!

It was a success!

A flash of excitement appeared in Lü Yongchang's eyes.

"Increase the current!"

Fang Xu's excited voice came from the side.

Lü Yongchang immediately turned the knob and slowly increased the current.

When seeing that the resistance value on the instrument screen didn't fluctuate at all, all the researchers in the laboratory let out soft exclamations.

Unlike the researchers around him, Lü Yongchang's expression remained solemn.

The test wasn't over yet.

He still needed to test the performance of this material in a low - pressure environment!

Lü Yongchang gave Fang Xu a wink.

Fang Xu nodded slightly and turned on the vacuum - pumping instrument beside him.

With a low humming sound, the air in the glass cover was gradually pumped out.

Watching the value on the pressure gauge slowly decrease, even Lü Yongchang broke out in a cold sweat.

You know, superconducting materials reacted extremely violently to environmental changes!

For previous superconducting materials, once the temperature or pressure changed even slightly, the superconducting effect would disappear directly!

Under the action of such a strong current, once the superconducting effect of the wire disappeared, even if the resistance value was very small, an extremely powerful amount of heat would be generated instantly.

The consequence... would naturally be the melting of this only room - temperature superconducting wire in the world at present!

Dozens of seconds later.

Looking at the calm resistance curve on the screen of the testing instrument, a bright smile finally appeared on Lü Yongchang's face.

He gently wiped the sweat from his forehead, raised his right hand high, and shouted loudly, "We made it!"

"We succeeded!"

Fang Xu beside him excitedly turned off one instrument after another, rushed to Lü Yongchang's side, and patted him hard on the shoulder, "Well done!"

"Now that we have the room - temperature superconducting technology, Academician Fang, it's time we prepared for the transformation of the stellarator!" Lü Yongchang quickly snapped out of the joy of success and said in a deep voice.

Fang Xu nodded with an excited expression.

"I'll go inform the laboratory staff right away. We'll start the transformation of the stellarator this afternoon!"
