Siheyuan: At the beginning, I can integrate everything!

Zhang Huaimin picked up the slightly yellowed drawing.

The paper was densely covered with various red and blue lines and data. This was the "crystallization of Yi Zhonghai's hard work" for this welding task, which he had spent several sleepless nights drawing.

In Yi Zhonghai's eyes, these blueprints were his talisman, irrefutable proof that he still had value.

but.

Zhang Huaimin glanced at it and couldn't help but sneer inwardly.

That's it?

This was the level of the early 1960s, full of blind confidence in empiricism, and completely devoid of the rigor of modern science.

"Whoosh!"

Zhang Huaimin took a red, thick-tipped pencil out of the pocket of his cotton-padded jacket.

Without any hesitation, and without the slightest respect.

He drew three glaring red circles on the three most crucial connection points of the drawing.

These three red circles are like three resounding slaps to Yi Zhonghai's old face.

"Master Yi, you've been a fitter for forty years, don't you even understand the most basic concept of 'thermal stress concentration'?"

Zhang Huaimin's voice was not loud.

But in Workshop No. 1, where it was so quiet you could hear a pin drop, the sound was as clear as a great bell.

Yi Zhonghai's body trembled violently, his bloodshot old eyes fixed on the red circle on the drawing.

"You... what nonsense are you spouting! What thermal stress! My fish-scale weld has been proven in real combat!"

Yi Zhonghai was still making a final struggle, his voice hoarse, like a wild beast roaring in despair.

however.

Zhang Huaimin completely ignored his roar.

He turned around and held the drawing with the red circle on it high in the air.

Facing the hundreds of fellow workers who were gathering in the workshop.

Zhang Huaimin's clear, youthful voice echoed under the workshop's dome.

"Please pay attention to the positions marked by these three red circles."

He stretched out his chubby little finger and pointed to the first node on the drawing.

"Master Yi used a continuous high-temperature deep welding technique here, which makes the weld look very full and beautiful, right?"

The workers watching nodded in agreement.

They learned it this way before and always thought it was the highest level of craftsmanship.

"Wrong! Utterly wrong!"

Zhang Huaimin suddenly raised his voice, his tone carrying an unquestionable authority.

His demeanor was nothing like that of a five-year-old child, but rather that of a top physics professor standing on a university podium!

"This special steel plate has an extremely high carbon equivalent. Although continuous high-temperature deep welding fuses the surface, the internal crystalline structure of the metal generates enormous shrinkage stress during rapid cooling!"

"If this stress has nowhere to dissipate, it will all concentrate at the root of the weld!"

Zhang Huaimin's gaze swept across the entire room like lightning.

"Imagine it like a rubber band stretched to its limit."

"It looks fine normally, but as long as a little external pressure is applied, such as the deep-sea pressure when a submarine dives, it will be able to withstand the pressure."

"With a 'bang!', the rubber band will snap instantly!"

"This is why, just a light tap, this supposedly 'perfect' weld cracked!"

boom!

Zhang Huaimin's "stress release theory" is extremely easy to understand, yet it hits the core of metal physics.

Like a bolt of lightning, it instantly shattered the fog in the minds of the hundreds of workers present!

"That's right! How come I didn't think of that!"

A veteran welder with over a decade of experience, holding a level 7 certificate, suddenly slapped his thigh, his face flushed with excitement.

"No wonder I could never pass the pressure test when welding this kind of high-carbon steel before; it turns out the internal stress wasn't being released!"

"Consultant Zhang's words are so insightful! They've truly enlightened me!"

Zhang Huaimin did not stop.

His red pencil quickly pointed to the second and third red circles.

"And this place, the preheating temperature and inter-floor temperature control here are completely based on personal intuition and are done haphazardly!"

"There is no scientific temperature control curve, and no proper annealing treatment."

"These works, built on so-called 'forty years of experience,' pale in comparison to true modern precision industry."

Zhang Huaimin turned his head and gave Yi Zhonghai, who was slumped on the ground, a cold glance.

Every word is piercing to the heart.

"It's not even a substandard semi-finished product; it's just a pile of scrap metal!"

Quiet.

The workshop fell into a deathly silence once again.

But this time, it wasn't because of shock, but because of awe, because of sudden realization!

Hundreds of workers watched the five-year-old baby standing on the high platform.

The disdain and blind following of the "child prodigy" were gone from his eyes.

Instead, there is a heartfelt, fanatical worship of top knowledge and truth!

"So all those amazing skills Master Yi taught us before were wrong!"

Someone in the crowd muttered something under their breath.

This sentence was like a spark thrown into a pile of dry wood, instantly igniting the emotions of the entire audience.

"Yes! I've always treated him like a god, but it turns out he's been misleading people!"

"With this level of skill, he still acts like he's the best in the world every day. I'm ashamed for him!"

"Consultant Zhang truly lives up to his reputation! This is a real expert! This is science!"

"Consultant Zhang is awesome! Long live Consultant Zhang!"

The workers' emotions were completely ignited.

They cheered and jumped for joy, as if they could see the hope of the Red Star Factory's technological leap forward.

And Yi Zhonghai, whom they once elevated to a pedestal.

At that moment, they trampled it under their feet without mercy and spat it into the mud.

Yi Zhonghai slumped down at the worktable.

He listened to the jeers, doubts, and insults that surged around him like a tsunami.

Every word was like a whip dipped in salt water, lashing his heart mercilessly.

His old face would turn bright red one moment and then turn deathly pale the next.

The alternation of red and white resembles a comical clown.

He has cultivated a technical aura for forty years, and he is proud of his identity as the "Chief Welding Instructor".

Faced with Zhang Huaimin's few understated scientific theories.

They went completely bankrupt.

They didn't even leave him a fig leaf.

He became the laughingstock of the entire factory, a fraudster who misled and deceived people!

This caused him more pain and despair than killing him!

Seeing this scene, Director Yang was so moved that tears welled up in his eyes.

He knew that the technological revolution at the Red Star Factory was truly about to begin!

"Great! Consultant Zhang's explanation is excellent!"

Factory Director Yang strode up to the platform and clapped enthusiastically.

Led by him, the entire workshop erupted in thunderous applause.

Factory Director Yang turned around and looked down at Yi Zhonghai, whose face was ashen.

His eyes were cold and resolute, without a trace of pity.

"Everyone heard that!"

Factory Director Yang raised his voice, and the sound spread to every corner of the workshop through the loudspeaker.

"Yi Zhonghai's technology is not only outdated, but also extremely dangerous!"

"This kind of reckless approach, relying on old experience, is irresponsible towards national property and workers' lives!"

"On behalf of the factory committee, I hereby officially announce!"

"Completely abolish Yi Zhonghai's honorary title of 'Chief Welding Instructor of Hongxing Factory'!"

"Strip him of all qualifications as a technical leader!"

"His welding method is a pile of garbage! Throw it in the scrap heap immediately!"

Rubbish!

These two words, once again, struck Yi Zhonghai's fragile self-esteem like a heavy hammer.

"I...I'm not trash...my fish-scale weld..."

Yi Zhonghai's eyes rolled back, and his lips trembled violently.

He wanted to stand up and argue back, to prove that he still had value.

However, his legs were as weak as noodles and could not support his heavy body at all.

"puff--!"

An uncontrollable surge of anger overwhelmed Yi Zhonghai, instantly rupturing his fragile cardiovascular system.

He suddenly tilted his head back.

It let out an extremely mournful and desperate cry, like a cuckoo crying blood!

"ah--!!!"

This was accompanied by a scream.

Yi Zhonghai's emaciated body resembled a piece of withered wood.

It crashed straight down onto the hard concrete ground behind it!
