Qu Jianlei held an alloy stick, knocking it back and forth.

Then, he picked up simple diagnostic tools from the warehouse and started testing the internal circuitry of the Mecha one by one.

At first, watching him hit things with the stick, the two onlookers were bewildered. Landes even glared at Ma Long.

But during the subsequent diagnostics, the two fell silent—the guy truly knows this model Mecha well.

Qu Jianlei took a total of ten minutes to diagnose the Mecha, then he put away his tools and spoke seriously.

"Your Mecha has major issues, many hidden dangers, it needs a complete overhaul!"

He found seven issues in total, including latent damage, worn-out components, and aging sensors.

"I can only guarantee these seven issues are real; I can't be sure if there are other problems."

Landes' face turned pale as he listened.

Although he wasn't a Maintenance Master, as a Mecha user, his understanding far exceeded that of the average person.

"These aren't just hidden dangers; they're life-threatening... Can you issue me a Maintenance Master certificate?"

"I never took the certification test," Qu Jianlei answered casually, "so I can't issue a certificate."

"Can't issue a certificate?" Landes looked at Ma Long in surprise, "Is this who you introduced to me?"

"You can have it checked independently at your own expense," Ma Long replied seriously, "If the issues are confirmed, the diagnostic fees should be reimbursable, right?"

Landes scratched his head and asked again, "Is this really trustworthy?"

"Our boss specially evaluated him," Ma Long spread his hands, "Do you think it's necessary to doubt his judgment?"

"Then I owe you one," Landes cupped his fist toward Qu Jianlei, "The hidden issue with the left leg support column should be relatively easy to detect."

He wasn't foolish; he didn't need to detect all seven problems, just verify one.

However, Qu Jianlei shook his head, "The wrist sensor on the mechanical arm is aging; that's even easier to detect."

"Thanks again!" Landes cupped his hands once more, this time with more courtesy, "Amazing you could do it with just a stick!"

Ma Long also nodded vigorously in agreement, yet he said, "Why not check a bit more?"

"Be reasonable," Qu Jianlei glared at him, "This is free, yet you're still demanding a lot."

"Brother, I'll treat you to a drink later," Landes expressed very politely, "You've basically saved my life!"

"Not necessarily life-saving," Qu Jianlei smiled and shook his head, "Impact Type Mechas are tough and resilient, not easy to break in a fight."

After saying this, he turned and left, leaving the two there staring at each other.

"Not easy to break?" Ma Long was dumbfounded, "Isn't he just a Modified Warrior?"

"What's so tough?" Landes forced a laugh, "It's just that C-level Warrior skills are a bit lacking, but what about B-level?"

The Inspection Bureau investigates wrongdoers, not only C-level but also B-level and even A-level.

"Let's get it checked first," Ma Long suggested, "I know a few Maintenance Masters, I can get someone to help for free."

"Free assistance," Landes rolled his eyes and couldn't help but mock, "The Ultimate Warrior status sure is impressive."

"Do they really charge outside for diagnostics?" Ma Long asked provocatively before touching his wristwatch.

"Let me check my contacts—some Maintenance Masters... B-level should be sufficient, right?"

A B-level Maintenance Master would have no problem reigning over a Settlement in a Gathering Area.

However, there are too many B-level Maintenance Masters in Central City, and when they meet an Ultimate Warrior, the usual response is to yield.

Soon, a B-level Maintenance Master arrived and straightforwardly began testing the sensors.

It took an hour to dismantle the sensor and another half-hour to test it before he exclaimed in surprise.

"This kind of atypical occasional aging... Who detected it?"

"It's a mechanical maintenance consultant here with us," Ma Long answered nonchalantly, "How's his skill?"

"This is the original sensor, even the factory seals are still on," the Maintenance Master smiled wryly, "Did it not get dismantled for testing?"

Ma Long and Landes shook their heads in unison, "No."

The Maintenance Master grew more curious, "How long did it take him to detect it?"

"Two or three minutes?" Ma Long wasn't entirely sure, "How's this guy's level?"

"I'm not qualified to comment," the Maintenance Master admitted, shaking his head in humility, "Even if he's not A-level, he's at least highly specialized."

Landes' eyes shifted slightly, "The guy took ten minutes to find seven issues."

Who said straightforward people can't be shrewd? These two traits aren't mutually exclusive.

Sure enough, the Maintenance Master fell for it, "What are the other six issues?"

After reading the explanation of the six other points, his face immediately changed. If he dared to handle the Mecha, he had the relevant professional competence.

"If they're all real, this Mecha indeed has a big problem, but..."

Composing himself, he continued, "He diagnosed this many issues in ten minutes?"

"That's right," Ma Long and Landes nodded in agreement, and Ma Long added, "He's our mechanical maintenance consultant."

"Truly, there's always someone better," the B-level Maintenance Master was in a daze for a moment and then gritted his teeth and cupped his hands.

"Master Ma Long, I hope to help this lord diagnose the Mecha... Just to check those six places."

"Why?" Landes questioned suspiciously, "I've already had it checked, do you want to charge the diagnostic fee again?"

"Free of charge!" the B-level Maintenance Master stated decisively, "I just want to see how strong this senior expert is."

"The consultant from our Inspection Bureau is indeed very strong," Ma Long replied proudly, "You can't compare."

"I know that," the B-level Maintenance Master said with a wry smile, "But I'm just curious."

Landes' eyes darted again, "Curiosity... comes with a price."

"This sensor... I'll replace it for you," the Maintenance Master gritted his teeth, "if all six issues really exist."

He feared the Ultimate Warrior, but a Mecha Warrior... what are they without the Mecha?

Landes smiled, "I'm not trying to make things difficult for you. The key is... the Inspection Bureau covers the Mecha repairs."

The B-level Maintenance Master thought for a bit and then said, "I'll invoice for the sensor."

"That's doable," Landes smiled and nodded.

He wasn't an especially greedy person, nor were Mecha Warriors particularly short of money.

A day later, he received the diagnostic report, "Indeed, our consultant from the Inspection Bureau is spot on!"

The B-level Maintenance Master hesitated a moment before asking, "Landes, can you tell me how that senior did the diagnostics?"

Landes wasn't greedy—those in the Inspection Bureau tend to act with a sense of propriety.

Then he directly stated, "He's not really a senior, the guy's quite young."

Jamaari had warned the people in Earth Room not to casually divulge Jian Lei's information, but what did Landes know?

"Huh?" the B-level Maintenance Master was dumbfounded, "Very young... Then how did he do it?"

Landes described what he'd seen, ending with a sigh, "...Just a stick."

The B-level Maintenance Master was stunned for a while before asking, "May I ask, what's this senior... consultant's name?"

"Jian Lei," Landes had no concept of keeping this secret, he didn't think a Maintenance Master's name was a big deal.

In fact, he thought it quite perceptive of himself to specifically inquire about the Maintenance Master's name.

"Jian Lei..." The B-level Maintenance Master pondered for a while, then his eyes suddenly lit up, and his voice turned tremulous.

"Is that the one who wrote the conceptualization of sensor bypass... on 'Mechanical Exploration'?"

"Huh?" Landes was a bit dumbfounded, "What are you talking about?"

"I'd like to meet that senior... that master," the Maintenance Master spoke earnestly, "Could you introduce me to his whereabouts?"

"That's not a big deal," Landes replied confidently, "Wait for me."

After a while, he returned looking dejected, "That consultant... has high clearance, doesn't need to work regular hours."

He genuinely hadn't considered that Earth Room would hire a consultant of such stature who wouldn't need regular hours.

But the B-level Maintenance Master didn't mind, having pondered over that sensor article and found it excellent.

He wouldn't find any preference strange for such a talent, "Could you introduce me to his residence?"

Landes did actually inquire about Jian Lei's address, "I do know, but the guy isn't easy to get along with."

He genuinely hadn't expected how keen Earth Room was to keep Qu Jianlei under wraps.

"Thanks a lot," the B-level Maintenance Master expressed his gratitude sincerely, "In the future, you can come to me directly, apart from Ma Long."

Qu Jianlei had no idea that after he left the Inspection Bureau, so many things happened.

He thought everything was settled, and he could start enjoying a recluse's life, but things went against his wishes.

With his arrival, someone came over to inquire about renting a ground-floor shop.

The first to inquire was the former tenant, who sold various materials for Maintenance Masters.
