A corner of the workshop, a material storage area.

Old Qian, codenamed "Mole," was still wearing his oil-stained work clothes, pushing a flatbed cart loaded with standard rivets and washers, slowly weaving through the busy crowd.

He was hunched over, his eyes were cloudy, and he looked like an honest man crushed by heavy work, completely out of place with the bustling atmosphere around him.

The flatbed truck passed through a relatively quiet area where several key pieces of the radar-absorbing skin were temporarily stored.

These skins have unusual shapes and are covered with a deep, matte coating, giving off a strange sense of emptiness.

Several large cardboard boxes and support frames that had just been unloaded and were awaiting processing were scattered nearby.

Old Qian's cloudy eyes swept over the leather with extreme subtlety, a greedy glint flashing deep in his pupils.

He pretended that one of the wheels of the flatbed cart got stuck in the oil on the ground, and with a cry of "Ouch!", he staggered and pushed the cart toward the pile of cardboard.

Whoosh!

The car crashed into a pile of cardboard, and several huge pieces of cardboard fell down, covering the "Black Feather" skin and the adjacent support frame.

The place was a complete mess.

"Oh dear! I'm so sorry! I'm getting old, my hands and feet aren't as nimble as they used to be..."

Old Qian hurriedly apologized, awkwardly bending down to steady the cardboard boxes, his movements as slow as a sloth.

Several workers nearby were busy moving a huge piece of the main wing skin. They glanced at it and cursed, "Old Qian, watch out!"

He then ignored it.

In the chaos, Lao Qian's hand inadvertently brushed against the edge of a piece of "Black Feather" skin that was half-covered by cardboard.

At his fingertips, a miniature high-precision scanner, disguised as an ordinary button, was discreetly affixed to the cold, smooth surface of the leather!

Buzz...

A very faint high-frequency vibration, almost completely drowned out by the loud noise of the workshop, came from his fingertips!

The tiny storage chip inside the scanner is recording the incredibly fine coating texture and edge geometry data on the skin surface at an alarming speed, data that contains some structural features!

Meanwhile, his hunched body blocked most of the view, and his other hand quickly wrote down the approximate size of the skin and the structural sketch of the adjacent support in a small notebook disguised as a scoreboard inside his sleeve, using coded symbols that only he understood!

The whole process took only a dozen seconds!

Old Qian lifted the cardboard box, muttering "I'm sorry, I'm sorry" under his breath.

Pushing the flatbed cart, they slowly left the area.

A fleeting, cold smile flashed in the depths of his murky eyes.

Key structural data fragments for the core absorbing skin... have arrived!

---

On the elevated platform.

Mingzhao's gaze was like a radar, sweeping across every corner below.

When Old Qian's cart knocked over the cardboard, her gaze lingered on that corner for a moment.

No obvious abnormalities were found, but a faint intuition, like being watched by a venomous snake, made her frown slightly.

She turned her gaze back to the key steps of wing-body fusion.

The massive main wing is being docked with the fuselage, requiring millimeter-level precision.

The workers chanted commands, the crane's steel cables were taut, and the huge metal component slowly approached under the action of the hydraulic jacks.

Sudden!

"Stop!" Ming Zhao's clear, cold voice suddenly rang out, piercing through the noise!

The crane and hydraulic system stopped instantly!

Everyone's hearts were in their throats!

Mingzhao's gaze was fixed on a tiny area where the main wing met the fuselage.

There, an unassuming titanium alloy calibration pad used for temporary positioning... its installation angle... seems to have an extremely slight deviation!

Against the backdrop of the massive structural components, this deviation was almost imperceptible to the naked eye, but within Mingzhao's mental energy range, it shone as brightly as a lighthouse in the night!

"Positioning pad, part number AX-7".

Mingzhao's voice was icy, "Angle deviation, 0.8 degrees counterclockwise. Disassemble and reassemble."

The team leader in charge of that area turned deathly pale! 0.8 degrees?!

How did she figure that out from such a small angle, on such a large component?!

But he dared not question it in the slightest and immediately roared, "Quick! Remove the padding! Reposition it!"

The urgent correction work immediately commenced. Mingzhao, like the most precise navigation system, reported the correction parameters in real time.

Sweat dripped down the workers' foreheads onto the cold metal.

Just then, Su Xuan, panting heavily and covered in sweat, rushed up to the elevated platform, clutching an oil-stained envelope in his hand—the very one Jiang Feng had handed over earlier!

"Comrade Mingzhao! Commander Huo's letter...you...you left it in the workshop! It was almost swept away as waste paper!"

Su Xuan shouted breathlessly, his voice hoarse.

Mingzhao's gaze shifted from the assembly line to the familiar envelope.

There seemed to be a barely perceptible fluctuation in his cool eyes.

She reached out and took the envelope.

She brushed her fingertips across the oil stains on the envelope and walked to a relatively quiet corner at the edge of the platform. She pulled out the thin sheet of paper again.

It was still that familiar, strong handwriting, and it was still that phrase, "longing for dusk."

Her gaze lingered on the three characters "Pan Mumu".

My fingertips unconsciously brushed across the paper, as if I could touch the warmth of that man's pen as he wrote.

The passionate yet clumsy kiss from the night before I left flashed through my mind again, along with the deep words, "I won't divorce you. I'll wait for you."

A heavy emotion called "longing" quietly wrapped around her heart like an invisible thread.

It wasn't intense, but it was exceptionally warm.

She didn't raise the corners of her lips as she did last time; instead, she carefully folded the letter back along the original creases with utmost care.

Then, he carefully stuffed the neatly folded letter into a special small compartment in the inner pocket of his work clothes, made of high-strength, high-temperature resistant insulating material!

That compartment was right next to her left chest, and it had previously been used to store only the most crucial miniature slide rule and a few key parameter cards!

Keep it close to your body, in sync with your heartbeat.

It's like guarding the most important... technological blueprint.

After doing all this, her expression remained unchanged, as if she had simply put away an ordinary tool.

She turned, her gaze returning to the bustling assembly line below, and her cool voice rang out, directing the tense wing-body docking:

"Move left 0.3 mm... Hydraulic jack pressure, hold... Okay, lock!"

The massive main wing and fuselage finally meshed perfectly amidst a piercing metallic scraping sound!

The rivet guns roared once again, signaling a breakthrough at a crucial juncture!

Watching Mingzhao's retreating figure as she resumed her work, Su Xuan subconsciously touched his empty chest pocket, scratched his head, and continued rushing down the platform with a blank expression, throwing himself into the new torrent of battle.

No one noticed that in the shadowy gap of a ventilation duct high up in the workshop, a pair of cloudy eyes were staring intently at Mingzhao's action of slipping the letter into her bosom on the elevated platform, and at her absolutely focused profile as she resumed giving instructions.

Those eyes were filled with cold scrutiny and greedy calculation.
