Cataclysmic Era: I can unlock the tech tree

After hearing Su Cheng's words, Lü Yongchang suddenly realized!

No wonder the main control program has been delayed!

He clearly remembered that in his previous life, when they were working on controlled nuclear fusion, the research team didn't encounter any difficulties with the main control program at all!

Therefore, he did not bother to learn about the main control program of nuclear fusion in detail.

Only now has he fully understood!

If all goes well, the existence and smoothness problems of the Navier-Stokes equations will likely be solved by an American mathematician in about five years.

And now...

Without theoretical support, the main control program is naturally difficult to develop.

Fortunately, Lü Yongchang had done some research on the Navier-Stokes equations at the time, and he had some recollection of the original proof process.

Lü Yongchang chuckled and nodded, saying, "I see... Do you have any paper here?"

The sudden turn of events caught Yuan Hongwei and Su Cheng off guard.

"Huh? What?" Su Cheng looked at Lü Yongchang with a puzzled expression.

Why would you suddenly ask for paper?

As for Yuan Hongwei, after a moment's hesitation, he gently pointed to the napkins on the desk: "Professor Lü, do you want those?"

Lü Yongchang: "..."

"Ahem! I mean, the kind of paper for writing, blank A4 printing paper is fine."

As he spoke, Lü Yongchang took out the fountain pen he always carried with him from his pocket.

Seeing Lü Yongchang's actions, Professor Yuan frowned and looked at him strangely, saying, "Professor Lü, you're not planning to solve the Navier-Stokes equations here, are you?"

Lü Yongchang chuckled, pulled out a chair, and sat down: "Of course!"

So, do you have A4 paper?

Yuan gave Su Cheng a wink, then hesitated before saying, "Professor Lü, the Navier-Stokes equations are no ordinary things; they're one of the seven Millennium Problems!"

Lu Yongchang reached out and took the stack of blank A4 papers that Su Cheng handed him, nodding nonchalantly: "Of course I know!"

As he spoke, Lü Yongchang lowered his head and swiftly wrote a calculation on the A4 paper with his pen.

"This...Mr. Yuan, what do we do now?"

Su Cheng walked to Elder Yuan's side and asked softly.

Yuan Hongwei did not reply, but frowned as he looked at the lines of equations written by Lü Yongchang.

Time slips away, bit by bit.

The blank spaces on the stack of A4 papers in front of Lü Yongchang were decreasing, and they were being replaced by densely packed, obscure formulas.

The doubt in Yuan Hongwei's eyes gradually faded.

When he saw Lü Yongchang write down an important equation, a look of surprise instantly appeared in his eyes.

"Brilliant!"

Afraid of disturbing Lü Yongchang, Yuan Hongwei lowered his voice and exclaimed softly, "So this step can be deduced in this way!"

As for Su Cheng, he was completely bewildered, his mind simply unable to keep up with Lü Yongchang's writing speed!

……

Two hours passed in the blink of an eye.

The scratching sound of pens in the control room suddenly stopped.

"call……"

Lu Yongchang exhaled a deep breath, then stood up and stretched his limbs.

"The...the certificate is out?"

A trembling voice came from the side.

Lü Yongchang smiled, tidied up the A4 paper covered in writing, and handed it to Yuan Hongwei.

"certainly!"

"What...what was the result?"

Upon hearing Yuan Hongwei's question, Lü Yongchang smiled and said, "It exists, and it is smooth!"

Yuan Hongwei's face flushed instantly: "Professor Lü... Professor Lü, you really..."

For a moment, Yuan Hongwei couldn't find a single word to describe Lü Yongchang in front of him.

"Now, the nuclear fusion control program should be resolved, right?" Lü Yongchang asked with a smile.

Yuan Hongwei nodded vigorously, a hint of excitement flashing in his eyes.

"certainly!"

"Professor Lü, rest assured! If I still can't solve the main control program for controlled nuclear fusion within half a month, you can hold me accountable!"

……

The White House in the United States.

A roar erupted from the president's office!

"impossible!"

"Absolutely impossible!"

"Fake news!"

Albert's face was flushed, and with his golden hair sticking out, he pounded on the desk in front of him.

"There is absolutely no way that the Xia Kingdom could complete such a massive project in three months!"

"It's all fake! Fake news!"

"Huff... huff..."

Perhaps because he had been too emotional, Albert's old face was as red as a monkey's bottom, and he was breathing heavily.

"Mr. President, I regret to inform you that this is true."

CIA Director William Blair shrugged, stepped forward, opened his laptop, and placed it in front of Albert.

"What is this?"

A hint of doubt flashed in Albert's eyes as he watched the construction video on his laptop, which was noticeably sped up.

"This is a live video broadcast by the Xia Kingdom's official authorities over a period of three months," William Blair explained expressionlessly. "As you can see from the video, in just three months, the Xia Kingdom built a complete nuclear fusion demonstration reactor on a piece of land full of gravel."

After watching the whole video, Albert's face turned green!

Where did this video come from?

William Blair paused for a moment before replying, "Mr. President, this is a video that appeared on Twitter this morning."

"After examination, the video was found to contain no false information."

Albert's face turned even greener after he learned that the video originated from Twitter!

"Where's my phone? Let me see what's being said on Twitter!!"

As he spoke, Albert hurriedly grabbed his phone, his large fingers laboriously tapping the screen.

"My God, Xia Guo is insane! They completed this construction task in just three months!"

"Jesus! Now I truly believe in China's reputation as an infrastructure powerhouse!"

"Leaving aside China, where is our US fusion experimental reactor? @Albert"

"Haha, the US's fusion reactor? It's probably still just a blueprint, right?!"

"@Ebert, Mr. President, we need an explanation!"

Albert's face darkened as he looked at the comments on Twitter.

"Professor Collins! Has Professor Collins arrived?!"

As Albert's shout faded, an elderly man with gray hair, leaning on a cane, squeezed forward, bowed to Albert with a fearful expression, and said, "Your Excellency, I am here."

"Hmph!" Albert scoffed irritably. "Tell me, where are we in our fusion reactor construction project?"

A hint of unease appeared in the old man's eyes.

"Currently... construction hasn't started yet!"

"Pfft...cough cough cough!" Albert spat out the cola in his mouth, coughed violently for a while, and then looked angrily at Professor Collins.

"Professor, are you kidding me?"

"It's been over three months, and our fusion reactor is still just on the drawing board?!"

"Listen up, starting right now, build a fusion demonstration reactor!"

Collins's expression changed slightly: "Mr. President, our plan involves a nuclear fusion experimental device..."

"The plan has changed!" Albert shouted, waving his hand. "What Xia can do, we can do too!"

"From now on, build me a demonstration pile!"
