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

The workshop was deathly silent.

This is a specially modified radiation-proof cleanroom, and in the very center, an old-fashioned ordinary lathe is humming.

In front of the lathe, an elderly worker with gray hair was sweating profusely, his vernier calipers trembling like leaves in the autumn wind. He was Master Yuan, a top-level "eighth-grade fitter" transferred from all over the country, who had dealt with metal more than he had eaten salt in his life.

But today, for the first time, he felt like an apprentice.

"Engineer He, Engineer Deng..." Master Yuan took off his goggles, his throat feeling like it was stuffed with cotton, "This job... I can't do it."

He pointed desperately at the dark, metallic sphere on the workbench—the core component of uranium-235.

"Our lathe is a defective product discarded by the Russians; the spindle runout error is 0.05 millimeters. But the precision you need..." Master Yuan swallowed hard, his voice cracking, "is 0.001 millimeters!"

"Moreover, this thing is radioactive and highly toxic! It must be made in one go; if even a single hair is cut off, this treasure, which cost the entire nation's hard-earned money, will be completely ruined!"

"If my hand trembles even slightly, I'll be a traitor to my nation!"

Upon hearing this, Deng Jiaxian frowned deeply, and the pencil in his hand snapped in two with a "crack".

Without high-precision CNC machine tools, this is the excruciating pain of being held back! No matter how perfect the theoretical calculations are, if the actual product can't be manufactured, it's all just a pile of waste paper!

"Can't we find a way to calibrate the lathe?" Lin Wanqiu's voice was full of anxiety.

"It's no use." Master Yuan shook his head vigorously. "This is a problem I was born with; my physical constitution is flawed. Unless... we can find a pair of divine hands."

Despair, like a plague, instantly spread throughout the workshop.

Is the painstaking "planting the sun" project going to be delayed by a whole year because of this tiny ball?

"Master Yuan, give me the knife."

A calm, emotionless voice suddenly rang out.

Everyone turned around abruptly and saw He Yuzhu slowly rolling up his shirt sleeves, revealing a pair of long, strong hands with distinct knuckles.

"Engineer He? Are you crazy!" Master Yuan's eyes nearly popped out of their sockets. "This isn't like cooking! If this cut is off by even the slightest bit, it could be cutting away the future of the nation!"

Deng Jiaxian also grew anxious and stepped forward to dissuade him: "Yuzhu, you are the chief designer. This kind of life-threatening, meticulous work..."

"What's wrong with being the chief engineer? I also came from a steel rolling mill."

He Yuzhu didn't bother to explain, put on his protective suit and walked straight to the lathe that would determine his fate.

[Ding! Host detected facing extreme industrial challenges!]

[Check-in successful! Location: Top Secret Core Processing Workshop!]

[Rewards: God-level Fitter Proficiency (Human CNC), Micrometer-level Perception (Passive), Radiation Resistance (Enhanced)!]

In an instant, He Yuzhu closed his eyes.

When he opened his eyes again, the whole world had changed in his senses.

The airflow speed, the slightest vibration of the lathe spindle, the stress distribution inside the metal sphere, the temperature of the tool tip... all this information flooded into the brain like a tidal wave, and was instantly analyzed by the [God-level Fitter] skill!

He is the super CPU of this dilapidated lathe!

"Turn it on," He Yuzhu said calmly.

Master Yuan pressed the switch with trembling hands.

"Buzz—"

The lathe started turning again, but He Yuzhu didn't even glance at the calipers or the blueprints. All the data was already imprinted in his mind in three dimensions.

He picked up a specially made cutting knife, leaned forward slightly, and his breath became steady as a rock.

Draw your sword!

"Sizzle—"

A very subtle, even somewhat pleasant, cutting sound rang out.

There were no sparks flying.

Only fine, hair-like metal shavings, like black silk, drifted down silently.

Outside the workshop, everyone held their breath. Lin Wanqiu covered her mouth tightly, feeling as if her heart was about to leap out of her throat!

Everyone knows that if He Yuzhu's hand trembles even slightly, beyond the limits of human capability, the uranium sphere will be destroyed on the spot!

But those hands were so steady, they were unbelievable!

As if welded to mid-air, it steadily advanced with a precision surpassing that of machinery!

One cut, two cuts, three cuts...

Fine beads of sweat seeped from He Yuzhu's forehead, sliding down his focused profile, but his eyes shone with an alarming brightness, as if his world consisted only of the spinning "sun's embryonic form" before him.

This is not just about processing a single part.

This is the carving of an indomitable dignity of a nation with the hands of ordinary people!

I don't know how much time passed, it felt like an eternity.

"Shut down."

As He Yuzhu's voice faded, the lathe slowly came to a stop.

The once rough black sphere was now as smooth as a mirror, gleaming with a cold and deep metallic luster under the light, as perfect as a work of art.

Master Yuan practically lunged forward, shakily picking up the micrometer and bringing it close to his finger.

Measurement.

Let's take the measurement from a different angle.

Try measuring from a different angle again!

A minute passed, and Master Yuan remained silent. His hand holding the micrometer trembled more and more violently, and his expression changed from tension to astonishment, and then to ecstasy!

"Old Yuan, how is it? Is he ruined or not?" Deng Jiaxian's anxious voice came from the radio, his voice trembling with worry.

"Clang!"

The micrometer in Master Yuan's hand fell straight to the ground.

He whirled around, tears welling instantly in his old eyes. Pointing at the perfect sphere, he roared in a hoarse, bellows-like voice:

"Amazing... fucking amazing!"

"The tolerance... is zero! Absolutely zero!"

"This is not something a human could do! It's divine intervention! This is a work of art! It's our national treasure!"

boom!

The entire workshop instantly erupted into chaos!

Several young technicians couldn't hold back on the spot, hugging the people around them and crying and laughing, acting like madmen.

Deng Jiaxian was so excited that he rushed up and gave He Yuzhu a big bear hug, disregarding his status.

"Yuzhu! You... what kind of cheat code did you use to do that?!"

He Yuzhu took off his protective suit, shook his slightly sore wrists, took the towel Lin Wanqiu handed him to wipe his sweat, grinned, revealing a set of white teeth:

"Basic skills are nothing special; I practiced them by cutting potato shreds in the kitchen."

Lin Wanqiu stared at him intently, her eyes shining with a light that could almost melt steel.

These are hands that shouldn't be used for slicing potatoes.

These are clearly divine hands, capable of supporting the backbone of a great nation!

He Yuzhu stared at the perfect uranium sphere, his eyes as deep and unfathomable as the sea.

"Got the ball."

"Now, it's time to hear the sound."
