Siheyuan: I, Shazhu, started out as an army and became a general.

A deathly silence.

Despair, like a silent plague, spread wildly through the conference room.

Without blueprints or core parameters, months of hard work went up to nothing.

"Are you done talking?"

A cold voice, like a sharp sword, instantly cleaved through the suffocating silence.

He Yuzhu loosened his grip on Lin Wanqiu and stood up slowly.

He dusted off his cuffs and walked step by step toward Petrov.

He was half a head taller than Petrov, and his condescending gaze made the arrogant Russian feel uneasy.

"Mr. Petrov, have you forgotten something?" He Yuzhu pointed to his head, a playful smile curving his lips. "Paper can be burned. But how do you burn the things here?"

Petrov paused, then burst into exaggerated laughter: "Brain? You mean your cook's brain that can only flip woks?"

"That data involves tens of thousands of nonlinear equations. You're fucking telling me you memorized them?"

"Unfortunately." He Yuzhu's smile carried a hint of wickedness. "I may not have much else, but my memory is ridiculously good."

[Ding! The host is facing a challenge to national dignity!]

[Special Check-in Triggered: The Scene of Tearing Up the Agreement!]

[Rewards: Mastery of Nuclear Physics (Grandmaster Level), Supercomputing Brain (Passive: Calculation speed increased by 1000%), Absolute Memory Recall!]

You little system, you always surprise me at crucial moments!

A massive, ocean-like stream of data instantly flooded He Yuzhu's mind.

Those blueprints burned to ashes, and the top-secret Soviet notes he had glimpsed before, were now as clear in his mind as a 4K high-definition photograph, every line and every character!

He Yuzhu turned around, walked straight to the blackboard, and casually picked up a piece of chalk.

"Sizzle—"

The chalk made a sharp, piercing sound as it scratched across the blackboard, dispelling the gloom in everyone's hearts.

He didn't pause at all; his hand speed was so fast that it almost left afterimages.

$frac{partial rho}{partial t} + nabla cdot (rho mathbf{v}) = 0$

$P = P(rho, T)$

……

Lines of intricate formulas, resembling scribbled symbols, and terrifyingly precise parameters down to six decimal places, poured out of his hands like a waterfall.

The only sounds in the conference room were the scratching of chalk across the blackboard and everyone's heavy breathing.

Petrov's smile gradually stiffened and shattered.

His eyes were practically bulging out of their sockets as he stared intently at the blackboard, his mouth agape enough to fit an egg.

This...this is the core parameter of the implosion that he just burned with his own hands!

No! That's not right!

It's even more streamlined and optimized than the original file!

"Impossible! This is absolutely impossible!" Petrov screamed like a cat whose tail had been stepped on. "You cheated! You read my top-secret notes?!"

After writing the last number, He Yuzhu flicked his wrist, and the chalk tip drew a perfect parabola in the air before landing precisely in the trash can a few meters away.

He turned around, behind him was a blackboard covered in cryptic writing, and in front of him were the stunned, speechless faces of Marshal Nie and all the scientists present.

His voice wasn't loud, but every word carried immense weight, sending shivers down one's spine:

"Petrov, you listen to me."

"If it's going to rain, it's going to rain; if a mother wants to remarry, she's going to leave. I won't keep you."

"But remember this: atomic bombs are used to scare spineless people; they can't scare the Chinese people who stand up!"

"The earth will still spin without you! I'll still make that mushroom cloud rise over the Gobi Desert!"

"roll!"

A furious roar filled the air, and murderous intent emanated from it!

Petrov was so frightened by this aura that he took three steps back and fell to the ground with a thud, looking utterly pathetic.

"good!"

Someone shouted first, and instantly, the whole place erupted!

The applause was thunderous and overwhelming, almost lifting the roof off the simple meeting room! Marshal Nie suddenly stood up, his eyes filled with tears, and clapped with all his might.

Looking at the man on the stage who seemed to be shining, Lin Wanqiu could no longer hold back her tears.

At that moment, she was completely captivated, willingly and wholeheartedly.

.......

The Soviet experts withdrew overnight, like a pack of stray dogs.

What they left behind was a pile of tampered and broken instruments and a mess.

But Base 221 did not collapse.

Everyone felt a fire ignite in their hearts because of He Yuzhu's words!

However, after the passion fades, reality is as cold as iron.

Although He Yuzhu replicated the core formula, verifying it required an astronomical amount of computation.

At that time, there was only one vacuum tube computer in all of China, located in Beijing, with a computing power of 10,000 calculations per second, which was not even enough to be considered.

"Engineer He, the amount of data is enormous, it's massive!"

The head of the calculation team, sporting dark circles under his eyes that could raise fish, clutched a thick stack of draft paper in his hand. His voice was filled with despair. "At the current speed of our hand-cranked calculators, it will take at least... at least three years to calculate the initial pressure of this detonation."

Three years? The daylily has already gone cold.

He Yuzhu sat in his office, twirling a pen between his fingers, his gaze deep.

The system gave him a "supercomputing brain," so he could calculate it all by himself.

But building an atomic bomb is like a thousand troops crossing a single-plank bridge; he couldn't be a lone hero. He had to lead an iron army that could fight tough battles!

"Without computers," He Yuzhu put down his pen, his eyes sharp as knives, "we'll use people to do the calculations."

"Calculate it by manpower?" The team leader was bewildered. "How do you calculate it?"

"abacus."

the next day.

The base's main auditorium was completely emptied.

Hundreds of tables were arranged in a long line, and hundreds of college students, retired professors, and technicians crowded together, their expressions solemn.

In front of each person, there was an abacus placed neatly.

This scene is truly a spectacle in the history of human science.

Using the oldest computing tools, we knock on the door of the world's most advanced and explosive nuclear energy.

He Yuzhu stood on the makeshift platform, holding a pointer, like a general commanding thousands of troops.

"Group one, responsible for the equations of state!"

"Second group, responsible for neutron flux!"

"Third group, cross-check!"

"Ready—Go!"

Crackling sounds!

In an instant, the sounds of hundreds of abacuses being turned simultaneously merged into a breathtaking sound wave!

That wasn't the clinking of abacus beads; it was the bugle call of a charging army! It was this indomitable nation launching a final assault against fate!

He Yuzhu's brain was working at lightning speed, and the [Supercomputing Brain] was at full power!

He not only had to oversee the overall situation and break down tasks, but also monitor the data flow of each group in real time, like a radar.

"stop!"

Amidst the intense calculations, He Yuzhu shouted, his pointer precisely pointing to a young technician in the corner, his brow beaded with sweat.

"Group 7, third line, data error. The decimal point is misplaced by one place."

The technician shuddered and quickly buried his head in checking the documents. After a moment, his face flushed red, he stood up and loudly reported, "Reply...report! It was really a mistake! I'm so sorry, Engineer He! I..."

What the hell!

Everyone in the audience was stunned.

With hundreds of people calculating at the same time, the sounds were as chaotic as a pot of porridge, yet he was able to tell by ear who had made a mistake on their abacus.

Is this guy even human?! Is that ear fitted with a listening device or radar?!

"Keep going! Time is precious, don't stop!" He Yuzhu said expressionlessly, as if he had only done a trivial thing.

And so it went, day and night without rest.

He Yuzhu didn't sleep for three days and three nights. His eyes were bloodshot, but his brain was working like a broken clock, becoming increasingly excited and alert.

Finally, in the early morning of the fourth day.

When the last set of data was brought to his hands, the entire auditorium fell silent.

Lin Wanqiu held the thin sheet of paper filled with the final results, her hands trembling uncontrollably: "Engineer He, this is... the key to detonating that sun?"

He Yuzhu took the paper, his eyes sharp, and quickly scanned it. After confirming that it was correct, he signed his name at the end.

He laughed, with a hint of wild pride.

"With it, we can plant a sun with our own hands on the Gobi Desert."

He turned to look out the window.

On the eastern horizon, a red sun breaks free from darkness and bursts forth, its golden rays instantly dyeing the boundless desert crimson.

Just then, the office door was suddenly pushed open, and Marshal Nie rushed in, holding an encrypted telegram and looking very excited.

"Yuzhu! Great news! Fantastic news! Your plan has been approved! And you've been assigned a new partner!"

"A new partner?" He Yuzhu was taken aback.

Marshal Nie excitedly stepped aside.

A middle-aged man in an old suit, wearing thick-rimmed glasses, and with a refined and modest demeanor walked in. He looked at He Yuzhu and gave him a gentle smile.

"Hello, I am Deng Jiaxian."

He Yuzhu's pupils suddenly contracted.

A hero of both nuclear weapons and missiles, a national hero without equal.

Finally, you've arrived.

He Yuzhu strode forward, without any unnecessary words, and with all his might, tightly grasped the hand that had written countless formulas and supported the backbone of the nation.

"Welcome, Engineer Deng! Let's work together to do something truly earth-shattering!"

In this simple mud-brick house, two giant hands, destined to change the world's landscape, clasped tightly together.

At this moment, the wheels of history were slammed on the gas pedal, speeding forward toward that earth-shattering roar from the East that would make the whole world tremble!
