With the plan set and the direction clear, the Red Star Factory, like a massive machine injected with a powerful stimulant, roared like never before around the core battlefield designated by the assault team. This was not a lone hero's act, but a meticulously coordinated, united effort in a collective battle.

Fu Jingchen's tireless efforts, day and night, are the core of the technology.

The office in the technical department assigned to the research team became a place that never sleeps. Fu Jingchen, along with several young technicians skilled in calculations, practically lived there. The desks were covered with draft papers filled with complex formulas and data, and the large blackboard in the corner was constantly being erased, rewritten, and updated with densely packed differential equations and material phase transformation curves. Based on the first batch of failed parts and a large amount of historical process data, they combined cutting-edge methods such as finite element analysis to construct a predictive model for heat treatment deformation.

"Here, the effect of cooling rate on the residual austenite content must be taken into account..."

"The constraints on shaft-type structures need to be revised; the previous model was too idealistic..."

The sounds of debate, keyboard clicks (using the factory's few old computers), and plotters mingled together. Fu Jingchen's glasses reflected the blue light of the screen as he sometimes pondered deeply, sometimes rapidly performed calculations, transforming the experienced descriptions of the master craftsmen into precise mathematical language, providing a theoretical basis and quantitative framework for the "pre-distortion" process. His presence was the "brain" and "navigator" of this technological innovation.

A pillar on the front line, Master Wang's presence and passing on of knowledge.

The atmosphere was heavy and focused within the designated test area of ​​the machining workshop. Master Wang Jianguo personally oversaw the operation, and several experienced and calm senior workers he had selected, like surgeons on an operating table, were conducting small-batch trial processing according to the "pre-abnormality variables" initially calculated by Fu Jingchen's team.

Master Wang remained silent, his hands behind his back, his eyes fixed intently on every step of the operation. The slightest sound of the cutting tool contacting the workpiece, the sparks flying from the grinding wheel—none escaped his ears or eyes. Occasionally, he would call a halt, step forward, re-measure the dimensions with a dial indicator, or feel the vibration of the cutting tool with his hand, then utter a few words: "Slow down the feed a fraction more," or "The coolant flow is insufficient."

He didn't explain much, but the executor immediately understood the problem. He was using his decades of accumulated, almost instinctive "feel" to add a final layer of insurance to the cold, hard theoretical data, ensuring that the "reverse" cut would land precisely where it was needed. He was not only a guardian of quality, but also silently passing on this exquisite art of control to the next generation.

Zhang Shulan, a vanguard in execution, is known for her meticulousness and perseverance.

Inside the "special zone" of the final assembly workshop, Zhang Shulan became the strictest "instructor" and "quality inspector" next to the brand-new assembly tools. She led several young workers in practicing the new assembly process again and again.

"The reference surface is confirmed to be clean and free of burrs!"

"Press the bearing in, check the gauge, the clearance must be between 0.02 and 0.025 millimeters, not even a millimeter more or less!"

"Before locking the positioning module, remeasure the axial movement!"

Her voice was clear and firm, brooking no ambiguity. Initially, workers accustomed to the old methods inevitably made mistakes, or subconsciously tried to adjust based on feel. Zhang Shulan was unforgiving, immediately stopping them, pointing to the operating manual, and demanding they start over. She knew the value of this tooling system lay in "eliminating uncertainty"; any bit of luck or carelessness could render all previous efforts futile. Under her strict supervision, the workers gradually went from discomfort to adaptation, and then to proficiency, assembling gearbox core components with unprecedented precision and consistency.

The soul of the organization, Liu Li's coordination and coordination.

Liu Li moved between various key points. In the technical department, she listened to Fu Jingchen explain the latest developments in the model, quickly understood, and made decisions; in the machining workshop, she communicated with Master Wang about the trial processing situation and assessed the risks; in the final assembly workshop, she reviewed the assembly data recorded by Zhang Shulan and evaluated the tooling effect.

She is the bridge connecting theory and practice, and the hub for allocating resources. When Fu Jingchen's model needed more experimental data for verification, she immediately coordinated with the workshop to arrange special test pieces; when Master Wang reported that a certain tool was wearing out too quickly and affecting accuracy, she immediately contacted the supply department to find a better alternative; when Zhang Shulan suggested that a certain detail of the tooling could be optimized, she immediately found the designers to make on-site modifications.

Her mind was like a high-speed central processing unit, integrating information from all sides to make timely judgments and deployments. The pressure was immense, but she displayed an almost ruthless calmness and efficiency. Her presence united this commando team, composed of people of different professions, ages, and personalities, into an organic whole with a unified goal and coordinated actions.

As night deepened, the factory canteen prepared special meals for the task force members, often letting the food cool to a crisp before they even had a chance to eat it. The lights in the workshop echoed those in the office building's technical section, like beacons guiding the way in the darkness.

No one complained, no one backed down. Because they could see that with the gradual optimization of pre-aging and pre-deformation correction processes, and with the skillful application of new assembly fixtures, the test data was gradually improving. The frustrating noise levels were steadily decreasing, and the early pitting marks on the gear teeth were also diminishing upon disassembly and inspection.

Hope, like a glimmer of light at the end of a dark tunnel, is becoming clearer and brighter through the selfless and concerted efforts of all the assault team members. The power of unity is gradually turning the seemingly unchangeable gears of fate.
