Chapter 202 Dignity is earned through fighting

"Sir, you... you are very professional."

The technician quickly reached under the counter and pulled out the hardcover brochure he had just claimed was "out of stock."

He handed it to Zhou Jianjun with both hands.

"Regarding dead-zone compensation, we have adopted the latest feed-forward control algorithm..."

The technician began to explain the technical details seriously.

His attitude was so sincere it was as if he were facing his university mentor.

As they left the booth, Zhou Jianjun, holding the brochure, said calmly to Lu Ning:

"Manager Lin once said."

"In the technical circle, dignity isn't gained by begging for it, nor by making a scene."

"It is 'scared' out of them."

"The more professional you are and the more biting your questions, the less they dare to treat you as invisible."

Lu Ning looked at Zhou Jianjun's back, his throat feeling dry.

Was this still the submissive Chinese delegation in his memory?

These were clearly a group of examiners with X-ray vision coming to 'grade the papers'!

...

The final highlight was the famous DMG booth.

This was where the largest crowd had gathered.

A massive five-axis simultaneous machining center was performing a cutting demonstration.

The cutter head spun rapidly, carving exquisite curves onto a complex aluminum alloy impeller.

Exclamations of wonder broke out from the crowd from time to time.

"Perfect craftsmanship!"

"This is the pinnacle of German manufacturing!"

The demonstrator was a middle-aged German man wearing a crisp uniform.

Holding a microphone, he was boasting incessantly in German:

"This is the current limit of physics!"

"Our dynamic response speed is at least five years ahead of the industry."

"For some countries with weak basic industries, this might be a distance they cannot close even in thirty years."

As he spoke, he gave a pointed look at He Zhenhua and his party, who had just squeezed into the crowd.

"This can be called the limit?"

He Zhenhua, who had been silent and elegant with his left sleeve hanging empty, suddenly smiled.

It was the kind of helpless smile one gives when seeing a child trying to show off their wooden sword in front of a master.

He didn't ask Lu Ning to translate.

Instead, he took a step forward.

He spoke directly in fluent German with a pure Bavarian accent:

"While I don't wish to interrupt your performance, sir."

He Zhenhua's voice wasn't loud, but it had a strange penetrating power.

"But just now, to hide the vibration of the spindle during high-speed direction changes, you limited the feed rate to 60%."

The entire venue fell silent instantly.

Everyone's gaze focused on this one-armed Chinese man.

The demonstrator's expression shifted:

"You... what nonsense are you talking about?"

He Zhenhua ignored his rebuttal.

He simply raised his right hand and pointed from a distance at several rapidly jumping green values on the control panel.

"The interpolation algorithm for the fourth axis clearly has a lag."

"If you don't mind, I can tell you why."

He Zhenhua's gaze was like a scalpel, precisely cutting into the root of the problem:

"In your PID parameters, the integral time constant is set too high."

"To pursue steady-state accuracy, you sacrificed dynamic tracking performance."

"This has caused the tracking error to exceed the limit."

"According to German Industrial Standard No. 3441..."

He Zhenhua said indifferently,

"This cannot be called the limit of physics."

"This is called a demonstration accident."

A deathly silence followed.

The German demonstrator's face turned pale instantly, and fine beads of sweat broke out on his forehead.

To be publicly pointed out for a parameter setting error by a foreigner, in his own mother tongue...

And to be accurate down to the specific control algorithm and standard number...

This was a direct slap in the face, and a resounding one at that.

He hurriedly lowered his head to check the background settings.

A few seconds later, the demonstrator snapped his head up, his eyes filled with unbelievable awe.

It really was an issue with the integral time constant!

"You... which master are you?"

The demonstrator's voice was trembling.

His previous arrogance had vanished, replaced by the humility of someone facing a grandmaster.

He Zhenhua straightened his suit collar and didn't answer.

He simply turned around, leaving the crowd with the back of a man who hid his achievements and fame.

Lu Ning stood there, completely stunned.

He felt his worldview being reshaped.

These were the country bumpkins from back home?

This is a max-level account smurfing in the starter village!

"Engineer Zhou, Engineer Tu, Engineer He..."

Lu Ning chased after them, his voice slightly out of tune,

"You guys are too amazing..."

"Who... who taught you all this?"

He Zhenhua stopped and looked back at the center of the exhibition hall.

The crossroads surrounded by Mazak, Siemens, and Fanuc.

He smiled and pointed in that direction.

"Besides that young man, who else could it be?"

Lu Ning looked in the direction he pointed.

The next second, his pupils dilated in shock.

He saw that in front of the simple Red Star Technology booth, which was originally thought to be a "dead zone."

It was actually crowded with people.

And in the center of the crowd.

Manager Lin, the youngest of the whole group, stood by a machine tool with one hand in his pocket, talking eloquently.

And those foreign engineers who were originally so arrogant they looked at people through their nostrils...

At this moment, they were all like elementary school students.

Craning their necks, listening with rapt attention, some were even frantically taking notes.

The image of the "ordinary youth" in Lu Ning's heart completely collapsed.

This Lin Xi... who on earth was he?

...

In front of the Red Star Technology booth, people were bustling.

Lin Xi stood in front of that 'Tianshu' machine tool, introducing it to the surrounding people in fluent English.

"Bosses, look over here!"

Lin Xi patted the thick cast iron base, which made a dull thudding sound.

"Don't listen to those big factories next door talking to you about micron-level precision or constant-temperature workshops."

"I only have one question—"

Lin Xi's gaze swept over the crowd, his voice rising:

"In your factories, is the voltage stable?"

"Is it hot in the summer?"

"Do the newly hired apprentices often crash the cutter heads and send them flying?"

The group of small and medium factory owners watching burst into laughter, and someone shouted loudly:

"Exactly right!"

"My factory is in Sicily, and that damn voltage is like my ex-wife's temper—never stable!"

Lin Xi smiled and pointed at the man:

"That's the point!"

"Those delicate precision machine tools trigger alarms as soon as the voltage flickers and shut down as soon as there's too much dust."

"But our 'Tianshu' is different."

He gave a thumbs up, his expression confident:

"Even if the power grid fluctuates by twenty percent, it keeps on working!"

"Its guide rails are widened hard rails—built to last!"

"An apprentice is clumsy and crashes the tool?"

"No problem, it's rugged!"

"Even if it breaks, the core components are all universal parts."

"You can hop on a motorcycle, go to a hardware store, and buy replacement screws and bearings!"

Lin Xi held up five fingers and shook them:

"For the price of one German machine tool, you can buy five of mine!"

"If one breaks, you still have four others frantically printing money. What do you call that?"

"That's called fault tolerance!"

"That's called a money-making machine!"

These words spoke directly to the hearts of those family-workshop factory owners.

In this era, not everyone needed to build space shuttles.

Most people just wanted to turn a few water pipe joints or make some motorcycle wheel hubs.

In front of the Red Star booth, inquiries about prices rose one after another.
