I chose one of four options at the start, and I chose the number one clan in Lingnan.

Workshop No. 3 of Hongtu Machinery Factory was filled with the pungent smell of machine oil and burnt smell.

Holding several repair reports, Lao Wei stood in front of the three imported five-axis CNC machine tools with burnt motherboards, so worried that he kept pulling his hair out.

His blue work clothes were covered in black ash, and his eyes were bloodshot.

A dozen or so elderly technicians with gray hair surrounded the machine, shaking their heads in disapproval.

Lin Ting, wearing a black trench coat, strode into the workshop. Lin Fei and Lin Dayou followed behind.

"Grandpa, the situation is worse than we thought." Old Wei stepped forward and handed the inspection report to Lin Ting.

Lin Ting didn't take the report; he only glanced at the three lifeless metal lumps.

"Tell me the results," Lin Ting said.

"The motherboard is completely burned through, and there is zero chance of repair. These three machines are German-made, and the original motherboards are not available in China at all."

"I contacted the agent in the south, but it will take at least three months by sea." Old Wei sighed and lowered his voice.

"Master Qiao has spoken, and all the parts suppliers and steel mills in the city have blacklisted us. Even buying a screw, no one dares to sell to Hongtu now."

Lin Fei gripped the steel pipe in his hand and slammed it heavily onto the ground.

"These bastards can't beat us, so they resort to underhanded tactics. Grandfather, I'll take some men and smash up those suppliers' storefronts," Lin Fei said through gritted teeth.

"If you smash up the storefront, will the machine start running on its own?" Lin Ting retorted coldly.

Lin Fei immediately shut up and took a half step back.

Lin Ting walked to the control panel in the center of the workshop, took out a thick stack of blueprints from the inside pocket of his trench coat, and slammed them onto the oil-stained table.

"If we can't buy them, we'll make them ourselves." Lin Ting pointed to the blueprints on the table.

Old Wei was stunned. He rubbed the grease off his hands and leaned closer to the table.

He turned to the first page, glanced at it twice, his eyes widened, and his breathing became rapid.

"This...this is the design drawing of a five-axis CNC machine tool? No, this kind of spindle structure and servo system has never been seen on the market before."

"These precision parameters require a micrometer level?" Old Wei's hands trembled as he brought the drawing close to his eyes, almost touching the paper.

"Can it be built?" Lin Ting asked.

Old Wei suddenly raised his head and waved his hands repeatedly.

"Grandpa, this blueprint was drawn by a god, but we are a mess that is about to go bankrupt."

Manufacturing micron-sized machine tools requires a sterile workshop with constant temperature and humidity, and a special alloy casting base.

"We don't even have decent dust removal equipment, how are we supposed to build it?" Old Wei slapped his thigh in frustration.

Lin Dayou stepped forward and pulled out a measuring tape from his waist.

"Old Wei, don't worry about the workshop. Grandfather has spoken, and even if Yitang turns this land upside down, they'll still build you a sterile workshop."

"How big of a space do you need? Mark the lines right away." Lin Dayou's voice was loud and clear.

"We didn't have enough materials, so we took all the old equipment from the warehouse to the blast furnace to melt it down and recast it."

"We don't have enough manpower. You can pick any young man in the entire Tazhai village. I only care about the results." Lin Ting stared into Lao Wei's eyes.

Old Wei gritted his teeth and slammed his hand on the table.

"Let's do it. As long as the site and materials are available, I'll lead these old guys, even if we die in the workshop, we'll dig this machine out."

Old Wei turned around and yelled at the dozen or so veteran technicians, "Don't just stand there! Get paper and pens, break down the blueprints, and pull out the list of materials you need!"

The veteran technicians swarmed around, grabbed the blueprints, and began calculating.

The entire Hongtu Machinery Factory was up and running.

Lin Dayou brought in two hundred bricklayers from Yitang, and overnight used special cement transported from Hongxing Cement Plant to partition off a completely enclosed area inside Factory Building No. 4.

High-powered exhaust fans and filters were brought back from other cities at high prices and operated 24 hours a day without stopping, creating a standard constant temperature dust removal workshop.

The blast furnace is ignited, and scrapped railway tracks and broken robotic arms are thrown in to melt.

Old Wei and his technicians stood by the furnace, adding rare metal scraps to the molten steel according to the proportions on the blueprints.

Sparks flew everywhere, and the sound of hammering was deafening.

Without high-precision polishing tools, the veteran technicians used the most primitive files and sandpaper, wearing magnifying glasses, to manually polish the guide rails and lead screws bit by bit.

Dozens of elderly people with white hair live and eat in the workshop. When they are tired, they take a nap against the wall, and when they wake up, they wash their faces with cold water and continue working.

Ten days later.

The door to the enclosed workshop was pushed open.

Lin Ting walked in, and in the center of the workshop, a rough-looking steel behemoth without any paint or external decoration lay quietly on a special cement base.

It lacks the streamlined casing of imported machines, and many parts even show hand-polished file marks. However, the key spindle and cutter head areas exude a high level of precision.

Old Wei's eyes were sunken, and his chin was covered in gray stubble. He held a red start button box in his hand, his fingers trembling so much he couldn't press it.

"Grandpa, the assembly is complete." Old Wei's voice was hoarse.

Lin Ting walked to the console and glanced at the green code flashing on the screen, which was the underlying runtime program generated by the system.

"Power on, load materials, test," Lin Ting ordered.

Old Wei took a deep breath and pressed the red button hard.

The massive machine tool emitted a deep rumble, without any harsh friction sounds, only the extremely steady hum of the servo motor.

The spindle began to rotate, and the speed increased rapidly, without even the slightest visible vibration.

Several workers used a crane to lift a high-hardness cylindrical alloy blank and fix it on a chuck.

Lin Dayou and Lin Fei stood to the side, holding their breath.

Old Wei entered the cutting program on the control panel and pressed the execute button.

The tungsten carbide cutting tip smoothly contacts the high-speed rotating alloy blank, causing iron filings to fly.

With the coordination of five-axis linkage, the cutter head can carve on the metal surface with unprecedented flexibility.

Without the spraying of coolant, the pure physical cutting is smooth and without any resistance.

In less than three minutes, the cutter head returned to its original position, and the spindle stopped rotating.

A mechanical bearing with a diameter of ten centimeters and an extremely complex structure appeared on the chuck.

Wearing white gloves, Lao Wei carefully removed the bearing and placed it on the testing table covered with velvet.

He picked up a high-precision micrometer, placed it on the outer diameter and inner ring of the bearing, and squinted to read the scale.

The workshop was completely silent, save for the heavy breathing of the veteran technicians.

Old Wei looked at the scale twice, then picked up a high-powered magnifying glass and carefully examined the cutting surface of the bearing.

"How much?" Lin Ting asked.

Old Wei put down the magnifying glass, picked up the bearing with both hands, and tears streamed down his oil-stained face.

"Micron-level accuracy, 0.002 millimeters. The cutting surface requires no secondary polishing."

Old Wei's voice was trembling uncontrollably. He suddenly turned around and raised the bearing in his hand.

A dozen or so veteran technicians gathered around, staring at the gleaming metal, and burst into enthusiastic cheers.

Some people broke down in tears, while others threw their blueprints into the air.

This machine, crafted from scrap metal and hand-polished, outperforms all imported equipment on the market.

Lin Ting looked at the frenzied crowd and stuffed the two red walnuts in his hand into his trench coat pocket.

Old Wei wiped away his tears, held the bearing in both hands, and walked up to Lin Ting.

The factory manager watched as the machine tool cut out a perfectly mirror-finished bearing, and tears streamed down his face.

"Grandpa, with this, we'll be unstoppable in tomorrow's bidding for core bearings for provincial heavy industry enterprises!"
