19: A revolutionary battery has been developed, enabling a range of 10,000 kilometers!

Long Weiguo's teasing, which strongly implied matchmaking, caused Su Qingying's beautiful face—which had just managed to cool down—to instantly flare up again.

Lu Chen, however, seemed completely oblivious to the underlying meaning, merely nodding calmly.

"That's fine."

"Theoretical research indeed requires an absolutely quiet environment."

"Let's arrange it in the study of my... suite."

He spoke these words openly and honestly, without a hint of ulterior motive.

But to everyone else present, the meaning they derived was entirely different!

Especially Academician Li Zhenbang and Academician Zhang Jingtong, whose gazes toward Long Weiguo held a hint of, "You old fox, you're truly cunning."

As for Su Qingying, she was so embarrassed she wished she could instantly turn into a "Quantum Ghost" and simply phase through the wall to escape!

Going to his suite's study... for private tutoring?!

If this... if this got out, how could she face anyone!

However, before she could even protest, Long Weiguo, the "patriarch" of the group, decisively settled the matter... For the next half month, Lu Chen completely entered the "two-point-one-line" workaholic mode.

During the day, he presided over the P4 Laboratory, directing the team of national treasure-level experts—whose average age exceeded sixty—as they worked day and night to overcome various manufacturing challenges in transforming the graphene battery from a "sample" into a "product."

At night, he returned to his luxury suite to personally provide "one-on-one"... tutoring for the Ice Goddess who was defiant in spirit but honest in action.

It must be said that Su Qingying truly lived up to being the "smartest child" in Old Zhang's eyes.

Her learning and comprehension abilities were terrifying!

In just three days, she had gained a preliminary understanding of the "Non-Fermi Liquid" theory.

In one week, she could barely keep up with Lu Chen's line of thought and began attempting to use the "Electroweak Unification Theory" to deduce the phase transition model for Room-Temperature Superconducting Material.

Although the model she proposed was still, in Lu Chen's eyes... riddled with errors and laughably naive.

But this rate of progress was enough to make any physicist in the outside world feel ashamed.

And the way she looked at Lu Chen also quietly began to change during this half-month of "tutoring."

From initial "defiance" and "provocation."

To later "awe" and "adoration."

And now... she herself couldn't describe what kind of complicated emotion it was.

She only knew that her heart, which had been frozen for eighteen years, seemed... to be uncontrollably accelerating its beat.

Half a month later.

Dragon Shield Bureau, Third Underground Level, Product Testing Center.

This was one of the most heavily guarded places in the entire Dragon Shield Bureau.

Because this place stored Xia Country's... most cutting-edge, secret weapons.

And today, this place would welcome a miracle... one capable of overshadowing all those secret weapons!

Long Weiguo, Li Zhenbang, Zhang Jingtong... all core members of the Pangu Project were gathered here.

Excitement and... anticipation were written on everyone's faces!

In front of them, inside a testing room constructed from fully transparent, explosion-proof glass, three items were quietly displayed.

A latest model domestic "Huaxing" mobile phone.

A military "Sharp Sword" unmanned reconnaissance aircraft.

And... a latest model "Han" series electric car, bearing the "BYD" logo!

Next to these three items, three Graphene Batteries of varying sizes, entirely black and radiating a metallic luster, were neatly arranged!

"Everyone!"

Lu Chen stood in front of the testing room, holding a tablet computer, smiling confidently like the CEO of a tech giant about to unveil a revolutionary product!

"It took fifteen days, mobilized three hundred and seventy-one top experts, and cost... an incalculable amount!"

"We have finally transformed the 'miracle' from the laboratory into a 'commodity' that can roll off the production line!"

"Today is the moment to test their quality!"

The moment his voice fell!

A technician wearing a specialized uniform carefully inserted the smallest Graphene Battery, roughly the size of a mobile phone battery, into the "Huaxing" phone!

Then, he pressed the power button!

The screen instantly lit up!

The battery indicator in the upper right corner clearly displayed the words "100%"!

"First test item: Charging Speed!"

As soon as Lu Chen finished speaking, the technician plugged a specialized charging cable into the phone!

On the large screen nearby, a timer representing the charging duration began ticking rapidly!

Everyone's eyes were fixed on the rapidly rising battery percentage!

10%!

30%!

70%!

90%!

100%!

The moment the battery was fully charged, the timer steadily stopped at—[32 seconds]!

"Hiss—"

A collective gasp filled the conference room!

Thirty-two seconds! To fully charge a phone battery?!

Is this even charging? This is practically light-speed transmission!

"Second test item: Extreme Endurance!"

Lu Chen didn't give them time to recover from their shock and immediately issued the second command!

The technician opened a specialized, super-large 3D game on the phone used for performance testing!

And set the graphics and special effects all to the highest level!

"According to our theoretical calculations," Lu Chen said calmly, watching the incredibly smooth game graphics on the screen, "under this extreme power consumption mode, its continuous endurance time should be around... three hundred hours."

"What?! Three hundred hours?!"

An expert responsible for communication technology cried out, "That's impossible! Even on standby, it couldn't last three hundred hours! That's more than twelve days!"

Lu Chen smiled and said nothing.

Facts speak louder than words... The subsequent tests were even more stunning than the last!

After the "Sharp Sword" unmanned reconnaissance aircraft was fitted with the Graphene Battery, its original maximum flight time of twenty hours immediately soared to... two hundred hours!

This meant it could continuously fly in the sky for... an entire week!

And when the final, and most anticipated, electric car test began!

The atmosphere in the entire testing center reached its peak!

The red "Han," after being fitted with the Graphene Battery—which was nearly identical in volume to the original Lithium Battery—was driven onto a circular track inside the testing center that simulated a highway!

"Begin testing!"

Following Lu Chen's command!

The red "Han" silently shot out like an arrow released from a bowstring!

On the large screen, a number representing the cruising range began jumping wildly upward!

100 kilometers!

500 kilometers!

1,000 kilometers!—Surpassing all electric vehicles currently on the market!

3,000 kilometers!

5,000 kilometers!

When that number finally, slowly, settled on a figure that made everyone feel their hearts stop!

The entire world went silent!

[10,324 kilometers!]

A range of 10,000 kilometers!

This was a terrifying figure, enough to cause all internal combustion engine car manufacturers worldwide to collectively go bankrupt!

This was a magnificent figure, announcing the complete end of an old era and the definitive arrival of a new energy era!

"Clang!"

A crisp, loud sound broke the silence!

Everyone looked over to see Long Weiguo, the General who was usually as steady as a mountain, had, in his extreme excitement, actually crushed his beloved ceramic teacup that he had used for over a decade!

Yet he was completely unaware!

His eyes were fixed intently on the dazzling number on the screen, and his entire body trembled slightly from extreme excitement!

He suddenly turned his head and grabbed the shoulder of a Military Equipment Department Chief standing nearby, who was also wearing a military uniform and bearing the rank of General!

His voice was hoarse, yet filled with an unprecedented, volcanic frenzy!

"Old Ye! Did you see that?! Did you damn well see that?!"

"A battery with a 10,000-kilometer range!"

"Do you know what this thing means if it's installed in our tanks, installed in our submarines, installed in our... fighter jets!!"

"What will that signify?!"
