87: Chapter 87: The Zero Value That Shocked Experts – The Ultimate Barrier for Domestically Produced Materials

The pale green liquid at the bottom was instantly drawn up by the wind pressure, climbing wildly along the inner walls of the glass, and surprisingly, it pulled out a pale green water curtain less than one millimeter thick, yet perfectly sealed, right in the middle of the three glass panes.

No matter how the wind pressure from the fan vibrated, the water curtain remained motionless, just like a solid piece of glass tightly sealing the air passage.

Wei Jianguo's pupils contracted sharply. Water flow resisting wind pressure? How could surface tension possibly be stretched to this extent!

"Don't be in such a hurry to gawk; the work isn't finished yet."

Song Changming fished a glass vial out from the bottom of his canvas bag, which contained half a bottle of pitch-black powder. He unscrewed the cap and poured a pinch into a tin can lid on the table.

"Sulfurized polyester, high-concentration lead dust, plus a bit of combustion enhancer." Song Changming pushed the tin lid in front of Wei Jianguo.

"Old man, didn't you complain that I didn't understand pollution?" Song Changming pulled at the corners of his mouth, revealing his yellowed teeth. He threw a one-yuan plastic lighter into Wei Jianguo's lap.

"Light it."

Wei Jianguo looked at the chemical waste in front of him, the veins on the back of his hands bulging. He understood this stuff; once ignited, the toxic smoke and micro-particles emitted by this dosage would be enough to drive the air quality in this fifty-square-meter prefab house to a severe pollution alarm.

"Song Changming! You're crazy! These are all pillars of the nation!" Chen Jianming roared.

Lu Chen tapped on the table. "Let him light it."

Since Lu Chen had spoken, no one dared to stop him again.

Wei Jianguo gritted his back teeth, grabbed the lighter, and flicked the wheel.

The flame moved close to the powder.

With a "boom."

The black powder ignited instantly, and a cloud of highly toxic black smoke, as thick as ink and carrying an extremely pungent, sour stench, erupted and shot straight toward the ceiling.

Several fluid mechanics professors were so startled that they hurriedly covered their mouths and noses, retreating repeatedly.

Just as the black smoke was about to disperse, Song Changming slapped the casing of the inferior fan.

The wind power surged, and the negative pressure chamber generated an extremely strong suction force. Before that thick black smoke could even disperse, it was as if it had been tightly grabbed by an invisible rope, and it was all sucked into that triangular glass groove along the pipe.

The black smoke crashed headlong into the pale green water curtain.

A miracle happened.

The ink-like thick smoke disappeared directly after passing through that water curtain, which was less than one millimeter thick. It was as if it had been swallowed in one gulp by an invisible monster.

The water curtain remained pale green and did not become murky. And at the other end of the air outlet, the air blowing out even carried a hint of cool, moist sensation, without a trace of pungent odor.

The conference room was deathly silent. Only the buzzing sound of the fan could be heard.

Wei Jianguo was stunned, and Wang Shouyi was also stunned. Several professors who had retreated to the corner of the wall stared fixedly at the crude glass groove, as if they had seen a ghost.

Song Changming turned his head and stared at the fluid mechanics professor who had just said he couldn't even reach the passing line.

"Bring over that 'Red Star-7' air dust detector you brought with you." Song Changming ordered.

The professor's Adam's apple bobbed, and he walked forward mechanically, pulled off the protective cover of the detector probe, and with trembling hands, inserted the probe into the glass tube at the air outlet.

Everyone's heads instantly crowded over, staring fixedly at the detector's four-inch LCD screen.

The machine emitted a slight "beep-beep" self-test sound.

The green data bar on the screen began to jump wildly.

Thirty seconds later, the values stabilized, and the breathing of everyone in the room stopped.

A few rows of glaring green fluorescent characters lit up on the screen:

PM 2.5: 0.000

PM 10: 0.000

Sulfide concentration: 0.000

Micro-dust particle capture rate: 100%

Class 10 ultra-clean standard verification status: Perfectly passed.

"Absolute zero..." Wang Shouyi gripped the casing of the detector tightly, his knuckles turning white. "How can it be absolute zero! This violates the conservation of mass. Where did those carbon particles and heavy metals go!"

"They were eaten."

Song Changming tapped his finger against the outer wall of the glass water tank.

"The heavy metal compound solvent I formulated can degrade any solid micro-dust or harmful gas that comes into contact with the water curtain at a molecular level within 0.5 seconds. They are directly precipitated into mud at the bottom, and the water curtain itself comes with a self-cleaning circulation system, let alone just a little combustion waste."

Song Changming straightened his back and looked down at Wei Jianguo from a superior position.

"Even if you old guy detonated a tear gas canister in this room, as long as my water curtain wall is up, not a single speck of dust will ever land on your Lithography Machine's lens."

There was complete silence in the prefab house.

This was a technical crushing. Using a broken, tea-stained jar and a pile of junk waste, he had torn the international breeze filtration blockade, which had monopolized the field for decades, to shreds.

Wei Jianguo closed his eyes and took a deep breath. The air only had a refreshing, moist sensation.

He straightened his body, and then, this white-haired national-level chief engineer, who had worked in the semiconductor industry for over thirty years and would rather shoulder millions in debt than bow to capital, pressed his hands tightly against his thighs.

He bent down ninety degrees and bowed deeply to Song Changming, this man who was covered in sour stench and looked disheveled.

"Chief Engineer Song, I am sorry." Wei Jianguo did not raise his head, his voice ringing out clearly. "It was my shortsightedness. The ancestors said that a hero's origin should not be questioned, but I have wasted my education. I apologize for my prejudice and arrogance just now."

Wang Shouyi and Chen Jianming behind him exchanged glances, and without hesitation, several industry titans bowed simultaneously.

There was no bureaucratic air, no stubborn obsession with saving face. True scientific researchers only recognize hard facts and only bow to more powerful technology.

Song Changming was stunned by the sudden bows from these people. He awkwardly stepped aside half a step and waved his hand impatiently.

"Alright, alright, enough with this superficial stuff! I hate your stuffy, pretentious rules the most." Song Changming pulled out a chair and sat down. "The technology is fine, but Factory Director Lu wants to build a 30,000-square-meter full-load ultra-clean workshop, and there's a big problem."

Lu Chen stubbed out the cigarette butt in his hand. "What's missing?"

Song Changming pointed his finger at the glass groove on the table. "When this thing degrades micro-dust, it generates highly corrosive secondary acids. Plastic pipes, ordinary copper pipes, or even industrial-grade stainless steel on the market can't withstand it; they will be burned through and leak within three hours."

Song Changming looked at Lu Chen, his expression becoming very serious.

"To contain the large water curtain circulation for the entire workshop, the core anti-corrosion pipe network must be made of special ultra-acid-resistant titanium alloy with a purity of 99.999%. If it's off by even one-thousandth of an impurity, once the pipe bursts, the entire workshop will be ruined."

Wei Jianguo, who had just straightened his back, suddenly stiffened, his face turning pale.

"99.999%?" Wei Jianguo's voice trembled. "Chief Engineer Song, are you kidding me? The current special steel plants in the country can only refine up to 99.8% at best. The remaining impurities, limited by blast furnace temperature, simply cannot be stripped out. Aerospace-grade acid-resistant alloys of that purity are all held in the hands of Morgan!"
