Chapter 570: Exquisitely crafted, the original aspiration remains

In the afternoon, sunlight streamed through the glass windows of the Research Workshop, slanting down and casting long shadows on the floor, also bathing the silver-gray Stealth Bomber in a soft halo.

The workshop remained a familiar scene of busy activity; the instruments' hum was neither loud nor soft, as if accompanying everyone as they slowly refined every detail, without the tense rush of yesterday's joint debugging, now with added composure in pursuit of perfection.

Lin Zhengcheng did not shuttle between stations as he had in the morning; instead, he sat before the console, a thick joint‑debug data report and a detail‑optimization checklist spread before him, his fingertips lightly tracing each number on the paper, his brows slightly furrowed, his expression intensely focused.

He meticulously checked the test data submitted by each team this morning, fearing to miss any tiny anomaly; even a fluctuation in the third decimal place would make him pause, ponder carefully, and re‑verify.

The water in the glass on the table had gone half‑cold; it was poured by Zhang Xiaoran before she left, but he didn't have a chance to sip, his eyes fixed only on the dense rows of numbers.

The joy of a successful joint debugging had long settled into a firm resolve; he knew that detail optimization was never something achieved overnight—every tweak of data, every reinforcement of an interface, every patch of coating directly affected the success of the test flight and of the entire research project, leaving no room for carelessness.

"Brother Zheng Cheng, here are this morning's navigation‑system test data; please take a look."

Xiao Zhang held a test report, walked lightly to Lin Zhengcheng's side, and gently placed the report on the desk, afraid to disturb him.

The wound on his hand, from gripping tools all morning, began to ache faintly again, his fingertips still a little numb, yet his face showed no complaint, his eyes full of seriousness.

Lin Zhengcheng lifted his head, took the report, and lightly tapped Xiao Zhang's shoulder with his fingertip, speaking gently:

"You've worked hard; rest a bit. If your wound hurts, apply more medicine—don't tough it out."

Xiao Zhang smiled and waved his hand, stepping back to stand aside: "It's fine, Brother Zheng Cheng; it doesn't hurt, I can persevere. I've thoroughly reinforced the navigation system's interface and optimized the anti‑interference algorithm. Here are the test data under various signal conditions—take a look; all parameters meet the requirements and the signal is very stable."

Lin Zhengcheng nodded, lowered his head and examined the report carefully, studying each page attentively and occasionally marking something on the data with his fingertip.

He turned to the last page and saw that the navigation system's positioning error in an extremely complex signal environment stayed within 0.3 m—better than expected—and a faint smile appeared on his face:

"Well done, the data are thorough and the optimization effects are clear. Still, you should run a few more tests, especially simulating high‑altitude complex signal conditions, to ensure there are no hidden risks—after all, the actual high‑altitude environment during a test flight will be even more complex than our simulations."

"Don't worry, Brother Zheng Cheng, I know." Xiao Zhang nodded firmly, "I'll go retest later, simulating several high‑altitude signal environments and repeatedly verifying the data, leaving no issues."

Having said that, he turned lightly on his feet, returned to his station, picked up his tools, and resumed testing the navigation system—his motions remained swift, though he would unconsciously rub his injured hand from time to time.

Lin Zhengcheng set aside the navigation‑system test report and picked up the avionics and weapons‑loading system report, which Chen Mo's team had just submitted. He examined the command‑response delay data on the report; each test's delay stayed within 0.0018 s, more precise than the specified 0.002 s, filling him with relief.

He lifted his gaze toward Chen Mo's direction and saw Chen Mo seated before the console, his fingertips flying over the keyboard, brows slightly furrowed, eyes locked on the screen's parameters, his focus so intense that one hated to interrupt.

Around Chen Mo, several technicians gathered, speaking in low voices about something, each face wearing a serious expression.

They were repeatedly testing the smoothness of the weapons‑loading command transmission, simulating the test‑flight weapons‑loading process; even the slightest hiccup would make them stop, troubleshoot, and retest.

"Run it once more; this time focus on the continuity of command transmission—there must be no hiccup at all." Chen Mo's voice was low but carried unquestionable rigor: "If a weapons‑loading command stutters during a test flight, the consequences would be unthinkable; we must achieve absolute reliability."

A technician immediately nodded, his fingers flying over the console to send the weapons‑loading command. The parameters on the screen flashed, the command‑response delay stabilized at 0.0017 s, transmission smooth with no hiccup. "Brother Chen, test successful—delay 0.0017 s, transmission smooth, no abnormalities," he announced loudly, a smile appearing on his face.

Chen Mo exhaled in relief, rubbed his throbbing temples, and the red veins in his eyes became a little more pronounced.

After days of all‑night work plus this morning's high‑intensity testing, his body was already somewhat fatigued, yet he dared not relax in the slightest. He rose, walked to the aircraft's weapons‑loading interface, carefully checked the connection, gave it a gentle shake with his hand to confirm it was firm and showed no sign of looseness, then nodded in reassurance.

"Everyone, take a ten‑minute break, drink some water, then we'll run one final comprehensive test to make sure the parameters stay stable."

Chen Mo turned to face the nearby technicians and said, his tone tinged with fatigue but still resolute.

The technicians nodded in turn, each finding a spot to rest—some sipping water, some massaging their shoulders, faces showing weariness, yet no one complained, for they all knew how heavy their responsibility was, and that every extra test added a measure of safety.

Meanwhile, Lin Qinhua was crouched at the tail of the fuselage, carefully treating the coating where the sheen had slightly changed.

She held a fine brush, dipped it in the prepared coating material, and applied it bit by bit to the coating surface, her movements gentle and slow, fearing uneven application that would impair stealth performance.

Her hair was a little disheveled, fine beads of sweat seeping from her forehead and sliding down her cheeks; she didn't even bother to wipe them, her eyes fixed only on the coating that needed repair.

"Qinhua, take a break, have some water—crouching like that, your legs must be going numb."

Zheng Juan approached with a cup of hot ginger tea, walked slowly to Lin Qinhua's side, placed the cup before her, and spoke with concern: "You've been busy since this morning without even catching your breath; if you keep this up, your body won't be able to take it."
