Chapter 252 My gun is for killing. Gao Kai seemed not to hear Old Man Sun's sarcasm; his entire attention was drawn to the small firing pin.
Its deep blue metallic luster and flawless concave surface seemed to possess a deadly magic.
He muttered to himself, his voice trembling without him even realizing it:
"No... this material... is chromium-molybdenum steel! And it has undergone carburizing, quenching, and low-temperature tempering... the hardness and toughness..."
"And this tail, it's not flat, it's a concave curved surface! My God... this design... this design..."
The more he spoke, the more agitated his voice became, until it almost turned into a gasp. He suddenly looked up at Old Man Sun, his eyes red. "Master Sun! Did you make this? You...you modified the firing pin?"
"Me?" Old Sun looked at him like he was an idiot and snorted heavily through his nose.
"If I had that ability, our country's light weapons would have surpassed those of Britain and the United States long ago! I would have been promoted to an expert at the Beijing Research Institute long ago! Why would I need to spend my whole life repairing guns in this godforsaken No. 3 Battalion?"
Gao Kai's mind went blank for a moment, as if something had exploded.
It's not Old Man Sun...
Who else could it be?
In the entire gun workshop, besides Old Man Sun and himself, who else knows about these things?
His gaze finally fell on the slender figure who had been standing by the C616A lathe since he entered, quietly wiping a part with cotton yarn.
Su An.
impossible!
This thought immediately surged wildly through his mind.
A female soldier, a female soldier who looks several years younger than him, how could that be...?
But that firing pin, which could be called a work of art, that perfect firing sound, and that incredible design concept all told Gao Kai a terrifying fact that he could not accept but had to believe.
Looking at his dejected appearance, Old Man Sun felt both relieved and complicated, and sighed.
"It's Comrade Su An."
"From designing the blueprints to selecting materials, and then to machining, quenching, tempering, and polishing on a lathe... she did it all by herself. I just watched from the side, not even knowing where to start."
She said it's called 'stress dispersion design,' which can evenly transmit the impact force of the hammer, making firing more stable and increasing the life of the firing pin by at least ten times.
At this moment, Gao Kai's entire worldview completely collapsed and shattered into dust.
Stress dispersion...
Increase lifespan tenfold...
These terms, which he had only seen in the most advanced foreign military research papers, were now easily realized by a delicate female soldier who looked younger than him, using an old-fashioned 1960s lathe.
During the day, she crushed his prized skill with a blind dismantling speed of seventeen seconds.
That evening, she unveiled a completely new design that he had never even dared to imagine, overturning his entire understanding of the profession.
His proud title of "firearms expert" was a joke in front of Su An.
He remembered his mockery of her during the day, his resentment at losing the bet, and his roars at her in the washroom that night…
My face instantly turned a deep liver color; it was truly shameful…
A mix of emotions made him wish he could disappear into the ground.
He looked at Su An's back, and she was no longer just a female soldier; she seemed like a mountain he could never reach.
