After being separated from my family, I became a darling of the military region thanks to my medical

Evening, the military alternate runway at Beijing Capital International Airport.

The setting sun turned the horizon a fiery red.

A massive Boeing cargo plane tore through the clouds, slamming heavily onto the runway with a sharp roar of its engines.

The tires emitted a pungent, burnt smell from friction, and the car slid for a full kilometer before coming to a stop.

The gangway was lowered.

Hans, clutching a silver-gray shockproof alloy case tightly, was the first to rush out of the hatch. Behind him followed two disheveled senior engineers, each carrying the same type of case.

Their suits were wrinkled like a pile of pickled vegetables, and their dark circles were as dark as a panda's. From the moment they took off from Munich until now, these three hadn't dared to close their eyes for a single second.

A military jeep was parked at the bottom of the gangway.

Gu Zheng leaned against the car door, a half-smoked cigarette dangling from his lips. He wore his civilian clothes with impeccable straightness, and his military boots were polished to a gleaming shine.

Upon seeing Hans, he straightened up and strode forward to meet him.

"Gu!" Hans's eyes lit up as if he had seen a savior, and he excitedly reached out his hand. "Smooth sailing all the way! The efficiency of German machinery is absolutely..."

Gu Zheng didn't reach out.

He sized Hans up and down, spat out the cigarette from his mouth, and spoke with the crispness of a soldier: "My wife said, inspect the goods first, then eat. If the goods are substandard, we won't even get plain water."

Hans's smile froze on his face.

He was inwardly cursing, but outwardly he immediately nodded vigorously: "Of course! I'll definitely satisfy Dr. Ye!"

Half an hour later, on the first basement floor of the Beijing Military Region General Hospital.

This is a cleanroom laboratory. The walls are painted with anti-static paint, and the exhaust fans overhead are whirring.

The door opened.

Ye Zhen and the others were inside, wearing white lab coats, their hair casually tied back with a black rubber band.

Gu Zheng walked over and casually shoved an enamel mug filled with warm water into her hand.

"Have a sip of water to moisten your throat."

Ye Zhen took the cup and drank half of it, her gaze immediately falling on the alloy box on the worktable.

Hans took a deep breath and stepped forward.

Click, click.

The six-digit combination lock popped open, and the alloy case lid was lifted.

A thin, long guide wire lay quietly in the sponge's groove. The entire guide wire was barely thicker than a human hair, and the microelectrode at its tip gleamed with a dim, metallic sheen under the cool incandescent light.

"Dr. Ye, the prototype of the radiofrequency guidewire." Hans puffed out his chest, his tone brimming with undisguised pride. "The culmination of seven consecutive nights of hard work by fifty top engineers at Siemens' Munich laboratory. The outer Teflon coating is heat-resistant to 300 degrees Celsius, with a conductivity loss of less than 0.1%. I guarantee with my life that this is currently the most sophisticated medical device on Earth!"

He stared at Ye Zhen's face, waiting for this Eastern enchantress to show shock, admiration, or even the slightest emotion. The two German engineers also held their heads high, waiting to be worshipped by the backward nation.

Ye Zhen didn't speak. She didn't even raise an eyebrow.

She took a pair of sterile medical gloves from the pocket of her white coat and slowly put them on. She pulled over a cold metal chair and sat down at the worktable.

Long, slender, pale fingers picked up a pair of medical tweezers. Her movements were gentle and precise, as if she were touching a newborn's delicate carotid artery. She carefully picked up the end of the guidewire, pulled it out little by little, and placed it steadily on the stage of the high-powered medical microscope next to her.

Focus, light, rotate the objective lens converter.

The view under the microscope becomes clear instantly, with magnification maximized.

The entire cleanroom fell into a deathly silence. Only the old clock on the wall ticked away, each tick like a blow to Hans's nerves.

ten seconds.

Twenty seconds.

Thirty seconds.

Time stretched on endlessly. Sweat began to bead on Hans's forehead. The two German engineers, who had been holding their heads high, also held their breath, their pride gradually hardening into surprise and uncertainty.

What is this woman looking at? This nano-level coating is flawless to the naked eye.

Snapped.

With a crisp click, Ye Zhen turned off the bottom light source of the microscope.

She straightened up, grabbed the edge of her right glove with her left hand, and ripped it off cleanly with a sharp tear. The movement was fluid and effortless; she didn't even glance at it before casually tossing the glove into the recycling bin at her feet.

She looked up. Her clear, black-and-white eyes were calm and undisturbed. There was no shock, no joy.

"Manager Hans," Ye Zhen finally spoke, her voice cold and metallic, "your lives are pretty cheap."

As soon as those words were spoken, the air pressure in the laboratory instantly dropped to freezing point.

Hans shuddered, his legs cramped, and he almost lost his balance.

"Dr. Ye, what do you mean? This is the most advanced manufacturing technology in all of Europe."

"1.2 centimeters from the tip electrode." Ye Zhen turned the tweezers in her hand upside down and touched a tiny spot on the outer sheath of the guidewire with the metal handle. "The coating thickness is uneven. It's 0.08 millimeters thinner."

The two German engineers were stunned, looked at each other, and the color drained from their faces instantly.

"Impossible. Absolutely impossible." One of the senior engineers, Klaus, jumped up like a cat whose tail had been stepped on. He couldn't help but retort loudly in broken English, his eyes red, "Our dip-coating process is calculated by the precision computers of Siemens' supercomputers. Even with machine wear and tear, the error would not exceed 0.05 millimeters. You are insulting German engineering."

"A tolerance of 0.05 millimeters is certainly acceptable for industrial cables."

Ye Zhen leaned back in her chair, her hands crossed on her knees. She looked at Klaus as if he were a primary school student who couldn't even do one plus one correctly. Her tone was as flat as if she were saying that cabbages had gone up two cents tonight.

"But this is meant to be placed in a person's heart."

Ye Zhen sat up straight, her eyes instantly turning as cold as knives.

"The 0.08 mm Teflon coating loss means that the impedance of this tiny point will undergo a fatal change the instant the high-frequency current is applied. When the radiofrequency devastates the locked muscle, the temperature in that area will instantly spiral out of control, exceeding the safety threshold of 47 degrees Celsius."

She leaned forward slightly, staring intently into Hans and Klaus's eyes with a menacing gaze.

"Do you understand anatomy? The cardiac conduction bundle is right next to the interventricular septum. Once the temperature exceeds 45 degrees Celsius, the conduction bundle will be completely and permanently burned."

Ye Zhen's voice was clear and bright, each word distinct. It was irreversible cell necrosis. It would cause the patient to experience third-degree atrioventricular block on the spot, leading to cardiac arrest.

The entire room fell silent.

Klaus's mouth gaped open wide enough to fit an egg; his previous arrogance vanished without a trace, and his throat felt like it was filled with shards of glass, unable to utter a single syllable. Hans's legs went weak, and he had to lean against the edge of the workbench to barely keep his balance.

Gu Zheng watched his wife exude a powerful aura, and a secret smile crept onto his lips.

Ye Zhen stretched out two jade-like fingers and gently picked up the radio frequency wire that carried millions of foreign exchange and symbolized Siemens' highest century of pride, as if picking up a weed.

With a flick of the wrist, a crisp clang rang out.

She threw the guide wire back into the alloy box without any pity.

"If this guidewire goes into my catheterization lab..."

Ye Zhen stood up and coldly swept her gaze over the three self-proclaimed elite German men.

"We weren't there to rescue anyone."

"It could be a murder weapon."
