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

Quiet.

A deathly silence.

The two German engineers' faces went from red to white, then to ashen. Their minds raced through the data, their anxiety growing with each calculation. The parameters Ye Zhen had given were theoretically flawless.

Ye Zhen did not get angry.

She didn't even lift her eyelids, and directly picked up the pencil and a stack of scrap paper from the table.

"Swish swish swish".

The pen tip flew across the paper. Minimalist geometric lines, precise fluid dynamics formulas, and complex parameter annotations flowed from her hand like water.

three minutes.

Ye Zhen pushed the scrap paper in front of Hans and tapped the paper twice with her fingertips.

"Single-layer dip coating is abandoned. The 'rotational triple gradient coating method' will be used instead."

"The first layer is the base layer, maintaining the pool temperature at room temperature; the second layer is the reinforcement layer, increasing the drying temperature by 15 degrees Celsius; the third layer is the sealing layer, further increasing the temperature by 15 degrees Celsius. At the same time, the guidewire rotates at a constant speed of 120 revolutions per minute."

Ye Zhen's voice was cold and firm, brooking no argument: "This process can keep the coating uniformity error in the tip area within plus or minus 0.05 millimeters."

Hans stared wide-eyed at the paper.

The more he looked, the more his hands trembled.

Two engineers came over, and after just one glance, their eyes nearly popped out of their sockets.

My God!

This coating solution is so logically sound that it perfectly solved the fluid adhesion problem that had plagued them for a whole year. This isn't just a modification; it's a revolutionary technological breakthrough! This process is a whole generation ahead of Siemens' existing technology!

"God...you are simply a god..." an engineer murmured to himself.

Hans suddenly raised his head, his eyes burning with a fanatical rage: "Dr. Ye, these... these blueprints..."

"Want some?" Gu Zheng cracked open a sunflower seed with a "crack," spat the shell precisely into the trash can, and patted Hans on the shoulder.

Hans nodded frantically.

"Alright, stop looking so gloomy." Gu Zheng brushed the sunflower seed crumbs off his hands, put his arm around Hans's shoulder, and smirked. "Come on, let's eat first. If it can be fixed, it's not useless. If it can't be fixed, then you can cry."

The atmosphere, like a taut rubber band, finally loosened a little.

Hans wiped the cold sweat from his forehead, feeling as if he had just been taken down from the gallows.

8 PM. Moscow Restaurant, next to the Beijing Exhibition Center.

The dome soars high, and the crystal chandeliers gleam.

Gu Zheng booked a small private room. The table was filled with borscht, braised beef in a pot, and cream-baked fish—all the most premium dishes.

The dinner was halfway through.

Ye Zhen wiped her hands and gestured with her chin towards Hans: "The second item."

Hans immediately put down his knife and fork, and like a primary school student waiting for the teacher to correct his homework, carefully carried the second, slightly smaller alloy box onto the table.

turn on.

Inside was a glass tube filled with specially made ice water. Floating quietly inside the tube was a thin, soft metal mesh, as fine as a thread.

"A sample of a nickel-titanium alloy self-expanding scaffold. The outer layer is covered with an ePTFE membrane." Hans didn't even dare to breathe too hard.

Ye Zhen stood up.

Gu Zheng immediately handed over a glass beaker filled with 37-degree warm water, the temperature of which he had just precisely measured with a stopwatch.

Ye Zhen used tweezers to pick up the support in the ice water, and with a flick of her wrist, quickly immersed it in a beaker of warm water.

"One, two, three, four, five," she counted silently in her mind.

The fifth second.

A miracle happened.

The metal wire, originally as soft as a dead snake, seemed to gain life and memory the moment it came into contact with the constant temperature of the human body. With a "pop," it expanded perfectly in the water, transforming into an exquisite miniature metal umbrella with a dense mesh and a smooth, flat ePTFE coating, without any damage or wrinkles.

Ye Zhen gently moved the object with tweezers to simulate the impact of blood flow.

As stable as Mount Tai.

She put down the tweezers and sat back down in her chair.

"This one," Ye Zhen nodded, a rare occurrence, "qualified."

"Hoo—" Hans let out a long breath, leaning back as if he were completely exhausted. The glass of red wine in his hand wobbled, and he almost spilled it all over his crotch.

"Don't get too excited." Ye Zhen picked up the water beside her and took a sip, then added, "The coating on the RF guide wire needs to be reworked according to my drawings. I need to see the finished product within a week. Also, provide two extra spare wires."

Hans said with a pained expression, "Dr. Ye, the rotating gradient coating method requires the equipment to be readjusted. We'll have to work three shifts a week straight at the Munich factory..."

"You'll cover the shipping costs," Gu Zheng added casually, placing a piece of braised beef from the pot onto Ye Zhen's plate. "Use the fastest express airmail. My wife needs it."

Hans gritted his teeth and slammed his hand on the table: "No problem! Even if the CEO has to personally go to the workshop to tighten the screws, I'll deliver it within a week!"

As the dinner party drew to a close, most of the dishes on the table had been eaten.

Hans's face was flushed, clearly indicating that the alcohol had broken down his defenses after he was under intense stress.

Gu Zheng waved to the waiter to come over, ready to pay the bill.

"No, no, no! I'll do it!" Hans jumped to his feet, stumbling as he pulled a thick wad of foreign exchange certificates from his suit pocket and slammed them onto the table. "Being able to treat Dr. Ye to a meal today is already the greatest blessing God has given me! Nobody can take it from me!"

Gu Zheng raised an eyebrow.

He hadn't even touched the money in his pocket, but upon seeing this, he immediately pulled his hand out and nodded very generously.

"Alright, our foreign guests have come from afar, so we should give them a chance to shine. Thank you for your expense."

Ye Zhen sat next to Gu Zheng and couldn't help but roll her eyes.

This scoundrel is getting better and better at extorting foreign businessmen.

……

Late at night, the streets of Beijing were quiet and deserted.

The late autumn night wind brought a biting chill, but the air still held the lingering fragrance of locust blossoms from the depths of the alley.

The military jeep drove smoothly on the empty road.

The car interior was dark, and a cassette tape played from the radio on the center console, Teresa Teng's gentle and lingering voice echoing softly in the cabin: "Though time flies by, I only care about you..."

Ye Zhen sat in the passenger seat, so exhausted she could barely keep her eyes open. The intense, back-to-back surgeries, coupled with the mental battle with Hans that evening, had nearly drained her of her energy.

She tilted her head, closed her eyes, and her forehead bumped against the cold car window intermittently with the car's swaying.

Gu Zheng held the steering wheel with one hand, catching a glimpse of this scene out of the corner of his eye.

He frowned slightly and slowed down.

He stretched out his free right hand, his palm gently supporting her forehead as she was about to hit the glass. His rough fingertips, calloused from years of holding guns, brushed against her soft hair.

With a slight flick of his wrist, he naturally turned her head and gently placed it against his broad, warm right shoulder.

Ye Zhen did not wake up.

She was like a cat that had found a safe nest, unconsciously rubbing against his shoulder in her sleep, finding the most comfortable angle, her breathing gradually becoming long and steady.

Gu Zheng did not move.

He drove extremely steadily, even slowing down the pace of shifting gears. The car window was only slightly open, and the night breeze blew in, leaving only a soft murmur.

Ahead lay the long shadows cast by the streetlights.

Forget about British special planes, forget about world problems.

At this moment, Gu Zheng's shoulders carried only the peaceful dreams of his wife.
