Live Stream 1980: Netizens Teach Me How to Make a Rocket by Hand

Mid-January, the general command center of the launch site.

Outside the window, the cold wind howled, but inside, it was warm and cozy.

Mr. Qian sat in a rattan chair, his eyes slightly closed, looking relaxed.

In front of him, a uniquely shaped fan was running silently.

It is the "Red Star Forest Oxygen Bar" fan.

There was no violent cutting sound from the fan blades, only an extremely faint hissing sound of electricity.

A gentle breeze, carrying the fresh scent of a forest after the rain, softly caressed the old man's face, as if he were in a mountain forest.

"This wind..."

Old Qian slowly opened his eyes, a hint of surprise in his gaze.

"That's interesting. It doesn't feel mechanical; it has more of a 'qi' feel to it."

Lin Xi, standing to the side, twitched slightly at the corner of her mouth, forcibly suppressing the upward curve of her lips.

He certainly knew what this "qi" was.

This is a negative ion generator that can be found everywhere at street stalls in later generations.

Combined with a carefully designed laminar flow duct, plus a touch of electrostatic dust removal.

But in 1981, this thing was definitely cutting-edge technology.

Especially recently, there's been a nationwide "qigong craze," and parks are full of elderly people practicing the Crane Soaring Stance.

"Professor Qian, this is 'ionized wind'."

Lin Xi said,

"By simulating the natural thunderstorm environment with a high-voltage electric field, active molecules in the air are stimulated, which helps improve the body's microcirculation."

"Microcirculation..." Old Qian's eyes lit up.

In this special era, even top scientists maintain a strong interest in the unsolved mystery of human science.

"Great! Good stuff!"

"I heard this fan cured Old He's old ailment?"

"Yes!" Lin Xi answered, forcing a smile.

Mr. Qian stood up, stroking the prototype in his hand.

"This stuff is much better than the boxes of tea I was going to give away."

"It is both technologically advanced and practical."

He turned to look at Lin Xi, a rare smile appearing on his face:

"Kobayashi, how many fans do you have left?"

"Prepare ten or eight for me."

"No problem! Plenty!"

Lin Xi was overjoyed.

What could be more impressive than Mr. Qian personally promoting products?

……

Two days later, a green train came to a clattering stop at the Beijing Railway Station.

During this "New Year's greeting trip," Lin Xi witnessed firsthand what it means to be a "top influencer of the times."

In those ministry compounds, the old leaders used to treat gift-giving as just a formality. Even if you were brought by Qian Lao, they would at most exchange a few polite words.

But when Mr. Qian demonstrated this "powerful" fan in a mysterious and rambling manner, the tone suddenly changed.

In particular, an elderly minister who suffered from insomnia started snoring on the sofa after sitting in front of a fan for ten minutes.

This scene cemented the reputation of [Red Star Forest Oxygen Bar].

Someone even quietly pulled Lin Xi aside and asked, "Comrade Lin, has this machine been blessed by a qigong master?"

Lin Xi suppressed a laugh, his face mysterious: "This is science, it's biomagnetic field technology..."

He didn't finish speaking, but the other person had an "I understand" expression on their face and was filled with respect.

Just as Lin Xi was busy making his face known in various ministries, Old Qian mysteriously took him to the Imperial Capital Hotel.

Inside a low-key yet luxurious suite.

An elderly man dressed in a Zhongshan suit is standing in front of the window.

His hair was gray, and he stood ramrod straight.

"Mr. Huo, it's been a long time." Old Qian grasped the other's hand tightly.

Lin Xi was startled.

Mr. Huo.

That famous patriotic businessman from Hong Kong was, in that special era, the lifeline connecting the mainland and the world.

"Is this the little kid who made the Germans so angry they were jumping up and down?"

Mr. Huo turned around and his gaze fell on Lin Xi.

Contrary to expectations, he was more like a friendly old man next door, but the occasional glint of shrewdness in his eyes made him someone not to be underestimated.

"Truly, heroes emerge from among the young."

"Your patent documents have caused quite a stir in Hong Kong."

"Young people these days are amazing."

Lin Xi stepped forward and bowed respectfully.

"You flatter me, Mr. Huo."

"Thanks to your help in processing the patent application in Hong Kong, Red Star was able to avoid being held hostage by foreigners."

"It was just a small favor."

Mr. Huo waved his hand, gesturing for the two to sit down, and personally poured tea.

"The country is in dire need of reconstruction, and we who do business abroad can help in any way we can."

"But Kobayashi..."

Mr. Huo then changed the subject, his tone becoming more serious:

"Your rare earth strategy is a big step, and also very risky."

"The West is stunned right now. Once they come to their senses, the blockade will be even tighter."

"I know."

Lin Xi took a pre-prepared document from her briefcase and pushed it in front of Mr. Huo.

"Therefore, I need to take some measures."

Mr. Huo opened the document, glanced at it, and his pupils contracted slightly.

"You want to use Hong Kong as a window to 'steal' sophisticated foreign equipment?"

Mr. Huo closed the file and gave Lin Xi a deep look.

"Mr. Huo, how can a scholar's actions be called stealing?"

Lin Xi corrected him, a shy smile on his face, "This is called international academic exchange."

Mr. Huo was stunned for a moment, then burst into a hearty laugh.

"What a wonderful academic exchange!"

"Come, tell me in detail!"

The lights at the Imperial Capital Hotel stayed on for a long time that night.

No one knows what the old man and the young man were plotting in the room.

No one knows what surprises this old man and young boy will bring to everyone in the future.

……

After the Spring Festival.

Late at night, in the cadre dormitory building.

Lin Xi locked the doors and windows, drew the curtains, and entered the live broadcast room that led directly to the future.

"Happy Chinese New Year, everyone."

"Let's get started!"

"Target: High-precision CNC machine tools!"

On the screen, the comments were refreshing rapidly.

[Is the streamer ready? This is a hellish dungeon!]

[Without a linear encoder or a high-precision servo motor, how would you build it?]

Even if you have the blueprints, current materials science can't support them!

Lin Xi smiled at the void: "Who said I was going to fabricate something?"

He spread out a yellowed sheet of letter paper and picked up an old-fashioned fountain pen.

"Everyone, please do me a favor," Lin Xi said in his mind.

"I want the core algorithm for future generations regarding the 'dynamic mapping compensation theory for multi-axis linkage nonlinear errors'."

"But I want you to 'translate' it into the mathematical language of the 60s."

The live stream chat exploded instantly.

[Holy crap, streamer, what are you doing?]

This theory only matured after 2010!

Disguising 21st-century algorithms as 60s manuscripts? That's academic fraud... no, that's dimensional reduction fraud!

[Got it! The streamer is trying to bait people!]

[Got it! Host, I'll find the information for you right away! Remember, leave three logical traps in the key matrix transformations; only top engineers of that era could spot these traps!]

Lin Xi lay hunched over his desk, the tip of his pen scratching softly.

Instead of using the usual engineering drawing fonts, he deliberately imitated a cursive English font.

The brushstrokes appeared somewhat trembling, as if they were written by an elderly man in his twilight years.

He drew an extremely complex error compensation curve on paper.

This diagram represents the "dynamic mapping theory" that was widely applied in later generations.

This paper solves the ultimate nightmare of precision mechanics in the 1980s: thermal deformation.

Lin Xi did not mention hardware improvements in his article, but instead proposed a set of mathematical logic for "complementing hardware with software".

Three hours later.

Lin Xi looked at the densely packed manuscript pages in her hand and blew on the still-wet ink with satisfaction.

Article title: "The End of Error: A New Logic for Ultra-Precision Grinding Based on Dynamic Mapping".

He did not write his own name in the signature section.

Instead, they wrote a strange code name: Watermen.

Lin Xi put the manuscript into a kraft paper envelope, sealed it with sealing wax, and pressed a blurry fingerprint on the seal.

The next day, Lin Xi went to the security office at the launch site and solemnly handed the envelope to the security officer.

"Please use the confidential passage and deliver this letter to Mr. Huo personally," Lin Xi instructed.

"Tell him to do everything he can."

"Publish this manuscript in the Swedish journal *Microengineering* or the German journal *Mechanical Engineering*."

Lin Xi squinted, looked out at the gray sky, and a cold smile appeared on her lips.

"The bait has been laid."

"Now, let's all get ready and wait for the big fish to bite!"
