Chen Fei scrutinized the frowning person opposite, proactively greeting him: "Hi! Need any help?"

The aviation maintenance software "Sky Eye Cloud Inspection" sometimes isn't a cure-all; if the sensors malfunction, it can be blinded due to incorrect data or lack of data.

"You, who are you? New here?"

The young mechanic stared blankly at Chen Fei.

An unfamiliar face, yet wearing the same maintenance crew uniform.

Could he be a newcomer too?

The 911 Aircrew Base is secluded, surrounded by sparse inhabitants, almost devoid of outsiders.

"I, Chen Fei, a member of the maintenance crew."

Chen Fei pointed to his nearly brand-new work uniform, still bearing mottled lubricant stains.

"Chen Fei? It's you!" Tha!n#ks! for r!ea.d$i+n#g—.b$r&o#ught^ to you by M|!VL-|EM^P!YR.%

The young mechanic felt a sense of familiarity, pondering briefly and remembering that the name was on the member list hung in the office of the maintenance chief, though he had never met him, and the maintenance crew was long one person short.

The young mechanic sized up Chen Fei, whose return remained a mystery, now adopting a better attitude: "Anything you need?"

"Big Brother Xiao asked me to see if you need any help? Also, how should I address you?"

The maintenance chief intended for Chen Fei to directly assist the young mechanic with his current problem but expressed it subtly.

The young mechanic nodded quickly: "Oh, thank you, if you're free, please help me check. My surname is Lin, call me Lin Xiu!"

To him, Chen Fei was a predecessor deserving respect.

Having "Xiu" in the name naturally suggests a role as a maintenance worker, whether fixing machines or people, fitting the maintenance crew vibe.

"Then I'll take a look first."

Chen Fei approached the "Big Mouth Monster," placing his hand on the aircraft.

This turboprop aircraft was purchased post-war by the company, not nearing overhaul by flight hours. Component replacements are covered, possibly with a labor fee subsidy.

"Here, take this!"

Lin Xiu handed his tablet to Chen Fei, despite having top-level access with Siege Lion Mode, unable to pinpoint the problem.

Gathering sensor data through onboard computers is the initial step in aircraft maintenance, promptly identifying fault locations saves time and trouble, else checking each aircraft assembly part is akin to dismantling and reassembling the entire aircraft.

Chen Fei didn't take the tablet with the software, explaining: "No need, I'm a Metal Ability User, I can assist with Psi Skill to locate the fault point."

To hear this, the young mechanic immediately felt his tablet was like trash, realizing his hard-learned skills were less potent than an awakening Psi Skill.

"You don't think relying solely on Psi Skill is enough, do you?"

Chen Fei took out tools, prying off the skinning, noticing Lin Xiu's expression, as the maintenance crew members are straightforward, transparent.

Lin Xiu, perplexed, remarked: "Isn't it?"

Being young and recently entering the workforce, his voice carried a hint of defiance.

Supernatural power users seem to cheat, learning nothing, blessed by Heaven, awakened effortlessly; others' hard work seems in vain, utterly unfair!

"Without a wealth of foundational knowledge and practical experience, determining pipeline pressure deviations, normal sensor blueing, or abnormal erosion remains challenging."

In front of Lin Xiu, Chen Fei swiftly removed the turboprop engine from the aircraft nose.

The massive engine, dismantled by hand, is a feat achievable only by Chen Fei in the maintenance crew, even Big Brother Xiao can't.

But in practice, Psi Skills merely fulfill various specialized tool functions; the "Big Mouth Monster" isn't cutting-edge tech, its PT6A engine series is universal, with over a century of development history, widely used from aircraft, agricultural machines, generators, to even tricycles at the 911 Aircrew Base—affordable and durable.

Industrial products feature high-volume production enhancing cost-effectiveness; otherwise, performance can't outweigh stringent costs obstructing everything.

"Not just sensor defects, but rapid aging here and here indicates quality issues. Report it to the manufacturer later, maybe a batch quality incident, Xiao Lin, fill out a material list for replacement."

Three moves and Chen Fei detached the defective assembly; sensor defects limit aviation maintenance software, otherwise coupling AI could redundate professional maintenance workers, but realistically, AI can't perform such complex judgments.

In domains bearing high uncertainty, human efficiency supersedes AI, electronic system debugging favors direct part replacements over logical fault assessments.

"Oh, oh!"

Witnessing the senior Chen Fei's efficient operation, Lin Xiu quickly assisted, finishing repairs on aircraft number 216 in under half an hour, restoring it to original condition.

The aviation maintenance software "Sky Eye Cloud Inspection" confirmed everything normal, fuel injected, engine started... a loud boom with the turboprop engine roaring continuously.

Ears perked briefly, engine cut-off.

"Done!"

Chen Fei gestured to Lin Xiu.

Despite a long absence, his craftsmanship hadn't slackened, in fact, honed to expertise.

Impressive! Lin Xiu gave Chen Fei a thumbs-up.

Listening to the steady roar of the 216 aircraft's engine from afar, the maintenance chief Xiao Ming nodded at Chen Fei.

Veterans possess the ability to diagnose faults solely by operational noise, locating the fault points.

Spending the entire afternoon in the hangar, Chen Fei visited the dining hall by dusk. Amidst the busy kitchen staff, he didn't spot the familiar Chef Abel; a query revealed the Gallic head chef retired six months prior.

In truth, considering Abel's age, he had long surpassed retirement age, serving passionately at the 911 Aircrew Base until back issues compelled resignation and return to Gaul for recovery and rest.

Unbeknownst to Chen Fei, during his absence, the base saw personnel changes, a typical phenomenon for military contractors where employee turnover is regular.

The current head chef is a young Korean from the Goryeo Peninsula, proficiently skilled in Chinese cuisine, offering variety beyond kimchi and rice, and markedly surpassing pre-made dishes or poorly cooked curry.

Barely having dinner, Chen Fei was encircled by colleagues from the "Genuine Fragrance" Combat Flight Squadron.

"Join us at the bar for a drink tonight!"

Noodles mixed with Erguotou, Squadron Leader Chekhov discovered a new flavor realm.

Pure Light Sparrow Xiao Jiu's sharp beak flickered, igniting a blue flame atop noodles.

Big Bear appeared indifferent, using the flame to seize as many noodles as possible with chopsticks before extinguishing the alcohol aroma, stuffing it, rookie style, into his mouth, scorching his beard curly, provoking Vice Squadron Leader Iline Rusios to slap him—didn't the smelly bear fear burns?

The "Genuine Fragrance" Squadron's pilots had long adapted to the bird's antics, laughing along.

"Maybe tomorrow night! The Boss arrives in the morning."

Chen Fei preferred avoiding disruptions due to drinking.

In the afternoon, he received a call from Boss Hana, who was already en route to the 911 Aircrew Base.

Recently, Hanna Gagel had been stationed at Chapala City headquarters on the South Continent of America; the North American Continent faced sudden social turmoil, inciting widespread fear, spiking demand for military contractor security services, prompting Jiu Defense Company to swiftly contract several assignments, oversight shifting unavoidably.
