Can't afford to pay for the takeout? Stunning CEO: Then pay with your body!

Chapter 72 If the Chief Engineer Can't Handle It, I Will!

The high-end manufacturing center of Qingcheng Group is located in the northern suburbs of Jinghai City.

The huge factory was brightly lit, with more than a dozen expensive five-axis CNC machine tools lying there, and the air was filled with the mixed smell of cutting fluid and machine oil.

But at this moment, the atmosphere in the factory was so oppressive that it made one want to cough.

"President Nie, it's not that I'm disrespecting you, nor is it that I, Lao Liu, am trying to shirk responsibility."

A middle-aged man wearing dark blue overalls and with messy hair was pointing at a pile of scrap on the workbench, shouting and spitting as he spoke.

He is Liu Tiejun, the chief engineer here, a top expert in the domestic CNC machining field. He is so arrogant that he doesn't even give the chairman much face.

"The blueprint you brought is utter nonsense!"

Liu Tiejun slapped the oil-stained blueprint repeatedly. "Double helical flow channel? 0.5 millimeters thick? And it needs to be machined on titanium alloy? Does the person who drew this even understand materials science? Do they understand stress relief?"

"This is just drawing on paper; if you actually put it on a machine, even a god couldn't produce it!"

Nie Qingcheng stood opposite him, dressed in a smart black suit, arms crossed, her face as cold as ice.

Behind her stood several key technical personnel, all with their heads bowed, not daring to utter a sound.

"Engineer Liu."

Nie Qingcheng's voice was steady, but those who knew her well could hear the suppressed anger in it. "These machines were imported from abroad by the group at a cost of 300 million yuan. Back then, you patted your chest and told me that you could make anything on Earth."

"That's normal!"

Liu Tiejun stiffened his neck. "This inhuman design is just asking for trouble! We tried it three times, and it exploded all three times!"

"Those are imported alloy blades! You might not care, but I certainly do!"

"and……"

Liu Tiejun's eyes flickered, and his voice lowered slightly, "This machine is acting strangely tonight. The system is slow to respond, and it keeps lagging when I input commands. I think the equipment probably hasn't been properly calibrated yet."

Nie Qingcheng took a deep breath, about to lash out.

"The equipment is fine; the problem lies with the people."

A clear voice suddenly pierced through the roar of the machines and came from the factory gate.

Everyone turned around in unison.

Zhang Yan strolled in, carrying a faded backpack and a bag of roasted sweet potatoes he had just bought from a roadside vendor.

His relaxed demeanor was completely out of place in the tense atmosphere of this heavy industrial setting.

"Zhang Yan?"

Nie Qingcheng's previously cold expression melted instantly. She quickly went to greet her, her tone carrying a hint of reproach mixed with undisguised dependence, "Why did you take so long? These old fogies almost drove me crazy."

Zhang Yan handed her the roasted sweet potato: "Eat it while it's hot. I saw the old man packing up his stall when I passed by earlier. These are the last two."

Nie Qingcheng was stunned for a moment, then subconsciously took the sweet potato.

The scalding heat spread throughout my body from my palms, and the anger I had just felt inexplicably subsided by half.

Liu Tiejun, who was standing next to him, almost popped his eyes out.

Is this still the same ruthless and fearsome "Bamboo Leaf Green"?

Holding a roasted sweet potato like a timid young wife?

"Who are you?"

Liu Tiejun sized Zhang Yan up and down, his face full of disdain. "Did you say those words just now? What do you mean by 'the one with problems is a person'?"

Zhang Yan ignored him and walked straight to the five-axis machine tool that was "on strike" there.

He reached out and touched the cold fuselage, the movement as gentle as caressing a lover's skin.

In his mind, the [Advanced Mechanical Manufacturing Mastery] skill was instantly activated, and countless data streams swept past his eyes like a waterfall.

"I drew the blueprints."

Zhang Yan turned around, looked at Liu Tiejun, and said in a calm tone as if stating a fact, "Since I drew it, I can build it."

"Did you draw this?"

Liu Tiejun seemed to have heard the biggest joke in the world. "Young man, you can eat whatever you want, but you can't say whatever you want."

"Judging by your age, have you graduated from university? Have you ever touched a machine tool? Can you distinguish between G code and M code?"

Several technicians nearby also let out a burst of snickers.

This is ridiculous.

How dare a mere youth try to teach Chief Engineer Liu a lesson?

Nie Qingcheng frowned, just about to speak up for Zhang Yan.

Zhang Yan waved his hand, indicating that she should eat her sweet potato without worry.

"You must be Engineer Liu?"

Zhang Yan walked to the control panel, his fingers hovering over the keyboard. "You're saying this machine is slow? Laggy?"

"Nonsense! The compensation command we just entered delayed it by a full two seconds!" Liu Tiejun snorted. "In this kind of precision machining, a difference of 0.1 seconds means it's scrap."

"That's not a problem with the machine."

Zhang Yan narrowed his eyes slightly, a sharp glint flashing in them. "That means someone added some 'seasoning' to your system."

As soon as he finished speaking, his finger suddenly fell.

"Crackling and popping—"

The sound of the keyboard being typed was as dense as a torrential downpour.

Zhang Yan's hand speed was so fast that only afterimages could be seen.

Instead of accessing the standard user interface, he went directly into the underlying Linux kernel of the utility machine.

On the screen, the original graphical interface disappeared, replaced by lines of rapidly scrolling green code.

"What are you doing! Don't touch that! This is precision equipment; can you afford to pay for it if you break it?!"

Liu Tiejun was shocked and rushed forward to push Zhang Yan away.

"Stop him."

Nie Qingcheng peeled the sweet potato while speaking calmly.

Two bodyguards immediately stepped forward, blocking Liu Tiejun like two iron towers.

"Mr. Nie! You're being ridiculous!"

Liu Tiejun was so anxious he was stamping his feet. "This kid is messing with the underlying logic! It'll crash!"

Nie Qingcheng took a bite of the sweet and sticky sweet potato, but her eyes were fixed on that focused figure, and a proud smile appeared on her lips.

"If it blows up, it's on me."

At the control panel, Zhang Yan's world consisted only of those dancing characters.

really.

Under his "hacking skills" (included in the CNC programming module of mechanical proficiency), a piece of abnormal code disguised as "tool wear compensation" is like a parasite, clinging tightly to the system's CPU resources.

Whenever the machine is about to perform high-precision cutting, this code sends a large number of junk data packets, causing the system to freeze and the tool head to deviate from its trajectory.

This is not a malfunction.

This is deliberate sabotage.

"Interesting." Zhang Yan's lips curled slightly. "Want to play dirty? Let's see who's ruthlesser."

Instead of deleting the virus directly, he quickly wrote a "sandbox" program, which acted like a cage to trap the "parasite".

Since you want to steal data, I'll give you something "good".

Zhang Yan tapped his fingers lightly, feeding the virus a piece of fake data that he had prepared beforehand and was full of logical traps.

All of this was done in less than three minutes.

"alright."

Zhang Yan straightened up and pressed the green start button.

"Buzz—"

The machine tool's spindle began to rotate, the sound deep and steady, completely free of the previous noise.

The tool magazine rotates, and a gleaming ball end mill is precisely gripped.

Coolant gushed out.

What happened next was something that Liu Tiejun and all the technicians present would never forget.

The milling cutter seemed to come alive, dancing wildly on the titanium alloy blank.

Fast forward, cutting, retraction, reversal... every movement is fluid and smooth, extremely fast, yet terrifyingly stable.

The double helix dead angle that Liu Tiejun originally thought would definitely "explode" was actually drilled into by the blade at an unbelievable angle, sliding through like an eel and leaving behind a series of perfect metallic streaks.

There was no lag.

There was no vibration.

The only sound is that pleasant "shh" sound when metal is being cut.

Ten minutes later.

The machine tool stopped operating, and the safety door slowly opened.

The white mist dissipated.

A uniquely shaped part, gleaming with a silvery-gray sheen, lay quietly on the worktable.

The complex double-helix flow channel is like a fine work of art; even under a magnifying glass, you can't find a single flaw.

The entire room fell silent.

Only the sound of Nie Qingcheng chewing sweet potatoes was exceptionally clear.

Zhang Yan picked up the part and casually tossed it to Liu Tiejun, who was still in a daze.

"Mr. Liu, shall we inspect the goods?"

Liu Tiejun hurriedly caught it, took out his vernier calipers and roughness tester, and began to measure with trembling hands.

One minute later.

"This...this..."

Liu Tiejun suddenly raised his head, looking at Zhang Yan as if he were looking at a living god.

"Tolerance... ±0.002 millimeters?!"

"Mirror-like finish?!"

"Is this even a human being capable of doing?!"
