Chapter 30 | The First High-Level Combat Mission

As dawn broke, a thin mist shrouded the dirt roads outside the town.Li Xing rode his bicycle, toolbox and spare parts in hand, silently making plans.Today's task was a complete overhaul of an old diesel engine on a farm in a neighboring town, more challenging than ever before:The machine had been used for a long time, resulting in severely worn parts.Oil lines were clogged, return springs were fatigued, and gears were slightly deformed.Any mistake could cause the engine to seize up or even break down.Li Xing checked his condition on the way:Emotionally stable; yesterday's tension had completely dissipated.Highly focused.Fingers, wrists, and shoulders were in good condition.Heartbeat was steady.All conditions were met; the controllable window was open.He exhaled softly, and the low-privilege space unfolded— The interface remained silent, but the tactile feedback and micro-vibrations were noticeably enhanced.This was the upgraded controllable window:Expanded sensing range.Simultaneous enhancement of subtle differences in force, friction, and temperature on parts.More subtle anomaly alerts, making it easier to detect potential risks early.Li Xing bent down and began disassembling the machine.Every bolt, every gasket, every oil passage operated in sync with his consciousness and spatial awareness.The low-access space didn't interfere with judgment, but merely amplified information precisely, like a subtle facilitator.In the first hour, he meticulously checked for blockages in the oil passages and unevenly stressed springs.The vibrations provided by the low access level allowed him to spot two easily overlooked, minute deviations early.Previously, relying on experience, it might have taken at least twice as long to detect them.In the second hour, he began fine-tuning the gear meshing and return spring tension.Each fine-tuning had to be perfectly synchronized with the spatial feedback; otherwise, even the slightest deviation could disrupt gear meshing.His breathing, touch, and spatial awareness were completely synchronized, as if the entire world was operating under his control.In the third hour, the most complex part arrived—the piston calibration of the old diesel engine.He had never completed a full calibration process alone before; the risk was extremely high.But this time, the subtly upgraded spatial feedback allowed him to accurately judge every minute piston misalignment.He operated while observing the spatial vibration feedback, correcting every deviation.Finally, the engine started smoothly.The sound was stable, the vibration even, and the fuel flow was smooth.The old farmer stood to the side, eyes wide:"Xingzi, you... this speed and accuracy are amazing! I thought it would take at least two or three days!"Li Xing simply nodded, without replying.He knew this wasn't just a victory of speed and accuracy—it was also the result of his first completely controlled collaboration with the space.In the evening, he returned to the courtyard, opened his notebook, and slowly wrote down his summary:—First high-level practical mission completed—The upgraded controllable window has indeed improved operational precision and risk control—The space still doesn't make judgments; all decisions are made by himself—After optimizing the synchronization window, more complex tasks can be handled, but potential backlash still needs to be guarded againstThe night was deep. He leaned against the edge of the kang (heated brick bed) and closed his eyes.Images of more challenging missions to come floated into his mind.He understood: from this moment on, his collaboration with the space had entered the true combat phase.
