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

three days later.

The special train sped across the desolate northwest plains, its wheels clattering against the rails in a monotonous roar.

The makeshift meeting room, converted from a train carriage, was filled with smoke, as if it were on fire.

Lin Wanqiu held a piece of chalk in her hand, drew a large cylinder on the blackboard, and then drew a machine the size of a truck next to it. Finally, she marked it with a hard cross with the chalk.

"It won't fit."

She threw a piece of chalk on the table, her voice dry and filled with a desperate weariness: "Our 1059 missile prototype has so little space in the warhead. But this vacuum tube inertial guidance system takes up half of that space just for heat dissipation!"

"If we force it in, we'll have to cut fuel, and the range will be at most 200 kilometers."

Two hundred kilometers? From here to the next county town.

Does the name "Dongfeng" deserve this range? It's an insult!

The conference room was deathly silent. Several senior experts were puffing away at their cigarettes, their fingers, stained yellow from the smoke, trembling, their brows furrowed so deeply they could trap a fly.

"Could you... make the vacuum tube a little smaller?" someone asked timidly.

"The limits of physics." Lin Wanqiu shook her head, the analogy hitting home: "You can't put an elephant in a refrigerator unless you chop it up."

"If you chop it up, is it still called an elephant?"

He Yuzhu sat in the corner, slowly twirling two agate stones he had picked up from the Gobi Desert in his hands, without saying a word.

His attention was entirely focused on the system panel in front of him.

[Mission Progress: Dongfeng Express (Phase 1). Current bottleneck: Micro control unit.]

"What if we use transistors?" He Yuzhu's voice wasn't loud, but it was like a stone thrown into stagnant water.

All eyes immediately turned to them.

"Transistor?" An old professor smiled wryly. "Chief Engineer He, who doesn't know how good that thing is? Small size, low heat generation."

"But the Americans have blocked this technology even more tightly than they have nuclear weapons! Our old Soviet big brother... after turning against us, he won't even sell us a single diode."

"There is one person who understands."

The door was pushed open with a bang, and there stood Marshal Nie, his face ashen, clutching a top-secret telegram in his hand.

He strode to the table and slammed the telegram down in front of He Yuzhu.

"Lu Guangda, a double PhD from MIT, is a genius in semiconductor physics."

"A year ago, I wanted to return to China. I was passing through Moscow when the Soviets detained me under the pretext of academic exchange and put me under house arrest in an apartment at Moscow State University."

Marshal Nie took a deep breath and lowered his voice: "Latest intelligence: he has a set of theoretical manuscripts on integrated circuits."

"This week, the Soviets are going to give him a final review. He'll either have to hand over the manuscripts and swear allegiance, or... go to Siberia to dig potatoes."

Lin Wanqiu jumped up: "Then what do we do? Didn't the Ministry of Foreign Affairs intervene?"

"I protested a hundred times, and the reply was always just four words: No such person found." Marshal Nie slammed his fist on the table, making the cups bounce.

He Yuzhu picked up the telegram; the photo showed a frail scholar wearing thick glasses.

[Ding! Emergency mission triggered: Icefield Hunter!]

Objective: To travel to Moscow, rescue Lu Guangda, and obtain the integrated circuit manuscript.

[Rewards: Photolithography machine schematic diagram (beginner level), high-purity silicon refining process, fluent Russian (maximum level).]

He Yuzhu put the two smooth, polished agate stones into his pocket and slowly stood up.

"No such person found?"

He laughed in anger, straightened his collar, and couldn't suppress the wildness of "Tiger He" in his eyes.

"Since the official records don't show this person, if he goes missing... probably no one will report it to the police, right?"

Lin Wanqiu was so frightened by the sudden burst of murderous aura emanating from him that she took a step back, her voice trembling: "Yuzhu, you...you're insane? You're the chief designer, not..."

"Late Autumn." He Yuzhu interrupted her, reaching out to straighten her collar which had been ruffled by the wind. His tone was gentle but firm, "I understand the missile casing, but the brain is something Professor Lu has to handle."

He turned to face Marshal Nie and gave a standard military salute.

"Sir, grant me three days off. I'm going to Moscow to buy some local specialties."

Marshal Nie stared intently at him for a full five seconds.

If anyone else had said that, he would have killed them on the spot.

But the one in front of us is the "Tiger" who captured the enemy commander Walker alive amidst the tens of thousands of troops at Changjin Lake!

"How many people do you need?" Marshal Nie asked in a deep voice.

"one."

He Yuzhu laughed, his white teeth gleaming in the smoke: "If there are too many people, the commotion will be too great, and I'm afraid our friendly nations will be surprised."

"Also, prepare my best suit, and... a handy bayonet."

……

That night, an unmarked transport plane roared into the vast northern night sky under the cover of darkness.

He Yuzhu sat in the cabin, feeling the violent turbulence, but his heart was burning with excitement.

[Host is about to enter the Red Square area. Loading agent template... Loading complete!]

The trivialities of a courtyard house? The infighting at the Red Star Factory?

Compared to what's happening right now, everything else is insignificant.

The scope has been broadened!

In this battlefield without gunfire, He Yuzhu is the true "villain of the entire hospital".

This time, however, this "evil" will be a real taste for those bandits who tried to lock up the dragon.

Moscow, your "King of Hell"... has arrived.
