After hearing Su Cheng's explanation, Lü Yongchang finally understood!
No wonder the main control program still wasn't finished!
He distinctly remembered that when they mastered controlled nuclear fusion in his previous life, the research team hadn't encountered any difficulties with the main control program!
Because of that, he had never looked into the fusion Main Control Program in detail.
Only now did it all become clear!
If events followed their original course, an American mathematician would probably solve the existence and smoothness problem for the NS equations five years from now.
But right now...
Without theoretical support, the main control program was naturally difficult to develop.
Fortunately, Lü Yongchang had studied the NS equations back then, and he still remembered some of the proof.
Lü Yongchang chuckled and nodded. "So that's it... Do you have any paper here?"
The abrupt change of subject left both Yuan Hongwei and Su Cheng momentarily bewildered.
"Huh? What?" Su Cheng looked at Lü Yongchang in confusion.
Why was he suddenly asking for paper?
As for Yuan Hongwei, he hesitated for a moment before pointing at the napkins on the desk. "Do you mean those, Professor Lü?"
Lü Yongchang was speechless.
"Ahem! I mean paper to write on. Blank A4 printer paper will do."
As he spoke, Lü Yongchang took the fountain pen he always carried out of his pocket.
Seeing Lü Yongchang's actions, Elder Yuan frowned and gave him a strange look. "Professor Lü, don't tell me you're planning to solve the NS equations right here?"
Lü Yongchang chuckled, pulled out a nearby chair, and sat down. "Of course!"
"So, do you have any A4 paper?"
Elder Yuan gave Su Cheng a meaningful look as he said hesitantly, "Professor Lü, the NS equations are no ordinary problem. They're one of the seven Millennium Prize Problems!"
Lü Yongchang took the stack of blank A4 paper Su Cheng handed him and nodded casually. "Of course I know!"
With that, Lü Yongchang lowered his head, his fountain pen gliding briskly across the paper as he wrote a line of equations.
"Well... Elder Yuan, what do we do now?"
Su Cheng walked over to Elder Yuan and asked quietly.
Yuan Hongwei didn't answer. He merely frowned as he watched Lü Yongchang write line after line of equations.
Time ticked steadily by.
The blank space on the stack of A4 paper in front of Lü Yongchang dwindled, replaced by densely packed, abstruse equations.
The doubt in Yuan Hongwei's eyes gradually faded.
When he saw Lü Yongchang write a crucial line of equations, delight instantly lit his eyes.
"Brilliant!"
Afraid of disturbing Lü Yongchang, Yuan Hongwei lowered his voice to an excited whisper. "So that step can be derived this way!"
Su Cheng, meanwhile, was already completely lost. His mind simply couldn't keep up with the speed of Lü Yongchang's writing!
Two hours flew by.
The scratching of the fountain pen in the main control room abruptly stopped.
"Whew..."
Lü Yongchang let out a long breath, then stood up and stretched.
"You... you proved it?"
Yuan Hongwei's trembling voice came from beside him.
Smiling, Lü Yongchang straightened the sheets of A4 paper covered in writing and handed them to Yuan Hongwei.
"Of course!"
"Wh-what's the result?"
At Yuan Hongwei's question, Lü Yongchang smiled. "The solutions exist and are smooth!"
Yuan Hongwei's face instantly flushed. "P-Professor Lü, you really..."
For a moment, Yuan Hongwei couldn't find a single word to describe Lü Yongchang.
"Now you should be able to finish the fusion Main Control Program, right?" Lü Yongchang asked with a smile.
Yuan Hongwei nodded emphatically, excitement flashing in his eyes.
"Of course!"
"Rest assured, Professor Lü! If I still haven't finished the main control program for controlled nuclear fusion within two weeks, you can hold me accountable!"
The White House, United States.
Roars erupted from the president's office!
"Impossible!"
"Absolutely impossible!"
"Fake news!"
His face flushed beneath his golden hair, Albert slammed his hand against the desk in front of him.
"There's no way Xia Country could complete a project that enormous in three months!"
"It's all fake! Fake news!"
"Huff... huff..."
Perhaps because he had worked himself into such a frenzy, Albert's aging face was as red as a monkey's backside as he panted heavily.
"Mr. President, I regret to inform you that it's true."
William Blair, director of the United States Central Intelligence Agency, shrugged, stepped forward, and opened the laptop in his hands before setting it in front of Albert.
"What's this?"
A trace of confusion crossed Albert's eyes as he watched the obviously sped-up construction footage on the laptop.
"This is footage from Xia Country's official three-month livestream," William Blair explained impassively. "As you can see, in just three months, Xia Country built a fully equipped Fusion Demonstration Reactor on an empty, gravel-covered site."
By the time he finished watching the video, Albert looked positively sick!
"Where did this video come from?"
William Blair fell silent for a moment before replying, "Mr. President, this video appeared on Twitter this morning."
"It's been authenticated. Nothing in it is fabricated."
When he heard that the video had come from Twitter, Albert looked even sicker!
"Where's my phone? Let me see what they're saying on Twitter!"
As he spoke, Albert hurriedly grabbed his phone, his thick fingers laboriously tapping the screen.
"My God, Xia Country is insane! They finished a construction project like this in three months!"
"Jesus! Now I believe Xia Country deserves the title of Infrastructure Maniac!"
"Never mind Xia Country. Where's our United States experimental fusion reactor? @Albert"
"Haha, a United States fusion reactor? I bet it's still sitting on the drawing board!"
"@Albert, Mr. President, we need an explanation!"
Albert's expression darkened as he read the comments on Twitter.
"Professor Collins! Is Professor Collins here yet?!"
As Albert's shout died away, a gray-haired old man pushed his way forward with a cane, bowed to Albert, and said apprehensively, "Mr. President, I'm here."
"Hmph!" Albert snorted irritably. "Tell me, how far along is our fusion reactor construction plan?"
Unease showed in the old man's eyes.
"At present... at present, construction hasn't started yet!"
"Pfft... cough, cough, cough!" Albert spat out the cola in his mouth. After a fit of violent coughing, he glared angrily at Professor Collins.
"Professor, you're joking, right?"
"It's been over three months, and our fusion reactor is still on the drawing board?!"
"Listen, starting right now, build me a Fusion Demonstration Reactor immediately!"
Collins's expression shifted slightly. "Mr. President, our plan calls for an experimental nuclear fusion facility..."
"The plan has changed!" Albert swept his hand through the air and shouted, "Whatever Xia Country can do, we can do too!"
"Starting now, build me a Demonstration Reactor!"
