Apocalypse: I Built the Infinite Train-Chapter 146: Robot Blueprints

"The system's self-check indicates that the main faults are concentrated in the drive module of the ascent track. These faults are typically handled as routine maintenance and aren't particularly complex. However, the problem now is that there are too many failure points, all of which fall under safety protocols. As a result, the system has been forced to shut down. We don’t have enough manpower, and we need to climb to the high-altitude section of the elevator to make the repairs, which will take considerable time."

On the vehicle, Wei Kexue explained to Lin Xian amidst the constant gunfire. "The engineers sent by Silver Star can help a bit, but their expertise is mainly in engineering repairs. Those maintenance areas are typically handled by a large number of maintenance robots. Relying solely on human effort is just too slow."

"Then why not activate the maintenance robots?" KIKI asked.

Wei Kexue waved his hand. "When we arrived here a few days ago, most of the maintenance robots were still functional. But yesterday, after Iron Guard Brigade encountered that Atmospheric Mica in Mount Daluo, they seemed to have been hit by some kind of ion pulse attack. This resulted in their core control boards burning out..."

Lin Xian frowned. "So the other ascent passages haven’t been activated not just because of insufficient power, but also because most of the airport’s master control programs have malfunctioned, right?"

Wei Kexue's expression turned grim as he nodded. "We’ve already sent an urgent request to headquarters to dispatch some maintenance robots for support, but... they won’t arrive in time."

"It’s already lucky that a few electromagnetic rail cannons survived. Otherwise, we would have had almost no air defense capabilities left."

"At the time, the horde tide wasn’t as severe as it is now. Those zombies and eerie entities hadn’t actively attacked the airport. It was only after the Iron Guard Brigade withdrew that the full defense mechanism was activated."

At this moment, the shuttle vehicle drove past the airport platform and began entering the massive ascent elevator pillar. The lighting changed suddenly, revealing a vast and magnificent megastructure before Lin Xian’s eyes.

As they moved deeper inside, countless transport corridors stretched upward. A massive black platform dominated the scene. All incoming trains and vehicles would first be prepared on this traction platform. Then, in three stages, they would be accelerated upwards in a near-catapult-like manner, surging up the ascent passage to a vertical height of 4,800 meters. From there, they would enter the High-Altitude Corridor above the Dazhu Plateau’s snowy mountains.

Inside the enormous corridor pipelines, the cargo would be electromagnetically accelerated to a speed of 1,000 km/h, allowing tens of thousands of tons of goods to be transported across 4,500 kilometers to Jiazhou City in under five hours—nearly as fast as a commercial airliner!

"Wei Gong, take me to see those maintenance robots."

Lin Xian spoke.

Attempting to fully repair the ascent elevator was clearly unrealistic—the sheer scale of it was comparable to a small city. Expecting his Mechanical Heart to cover the entire structure for repairs? He’d suffocate to death before finishing.

The only feasible way he could help was by manufacturing some key components based on existing blueprints.

However, from Wei Kexue’s explanation, this wasn’t just a matter of replacing a few parts. If they could restore the maintenance robots, the repairs would proceed much faster.

Wei Kexue looked up at him, remained silent for a moment, then nodded quickly. "Got it."

The shuttle vehicle swiftly drove into a large maintenance bay. Under the dim yellow lights, numerous conveyor chains and suspension platforms came into view.

Wei Kexue operated the computer system and activated the lights in a designated area. As the illumination flickered on, rows of small yellow maintenance robots appeared on the ground.

"These are PX-05 Engineering Robots specifically designed for ascent elevator maintenance. They are usually managed directly by the airport’s self-check system center. When the malfunctions started, a few colleagues and I tried to repair some, but we couldn’t get them running. The maintenance warehouse had some backup units, but the Federal Investigation Team took them for airship repairs before we could use them."

"The Federal Investigation Team again? Why the hell are they still here? All they do is make our lives harder!" KIKI said irritably.

Wei Kexue sighed helplessly. "Even though we belong to different factions now, Phoenix’s top priority is still to help as many survivors as possible. We can’t afford direct conflict with them. If everyone on Blue Planet dies, then our resistance will be meaningless."

Lin Xian didn’t respond. He walked straight over, placed his hand on one of the engineering robots, and activated Mechanical Scan.

【Scanning in progress… 15%】

【Scan progress… 50%】

These factory robots used small Hall-effect anode-layer thrusters for high-precision levitation operations. Just judging by the scanning speed, Lin Xian could tell that their engineering complexity was high.

However, he also noticed something surprising—these robots weren’t missing any structural components.

Unlike the previous wrecked Iron Guard-3 Military Mecha, which had lost its entire core, leaving only an empty shell that was useless except for Devouring, these PX-05 robots were still intact.

Since Devouring damaged and incomplete machines wasn’t particularly efficient, Lin Xian always prioritized restoring fully operational mechanical units whenever possible.

That way, he could obtain complete blueprints.

After about twenty minutes, Lin Xian finally completed the full scan.

【Scan complete: PX-05 Engineering Robot Blueprint acquired】

【Detected core control board circuit damage. Begin repair?】

Repair!

Seeing the prompt, Lin Xian finally breathed a sigh of relief.

A full set of robot blueprints—finally!

From the materials required, the construction wasn’t particularly complex. His current Mechanical Manufacturing skill level would make the process a bit slow, but with these blueprints, he could start mass-producing maintenance robots for train repairs.

He could even install machine guns or grenade launchers on them and turn them into battle robots!

BZZZZZ!

A soft hum filled the air. The mechanical circuits inside the robot flickered with blue light—a maze of intricate wiring that would be a nightmare for any normal engineer to troubleshoot.

But for someone with Mechanical Heart, repairs were effortless.

BEEP—"Program initiated."

The PX-05 Engineering Robot’s control panel lit up with a faint fluorescent glow, and a low electric whirr sounded as its thrusters ignited with a soft blue light—then, slowly, it hovered into the air.

"Whoa! It’s actually working!!"

Wei Kexue adjusted his glasses in shock, immediately checking the system. Sure enough, one of the engineering robots had come online in the system’s registry.

Lin Xian nodded. "The first one takes longer. Now I’ll fix the rest."

"That’s amazing!"

At that moment, Wei Kexue's eyes were filled with admiration.

For a mechanical engineer, Lin Xian’s ability was literally like a Mechanical God’s blessing.

With this skill, who even needed to study Kun’s 《Control System Engineering》, 《Mechanical Manufacturing and Equipment》, 《CAD & Mechanical Components》, 《Materials Forming Technology》, or 《Engineering Materials and Applications》?

For a moment, Wei Kexue wanted to apprentice under Lin Xian—but quickly dismissed the thought. This ability probably wasn’t something that could be taught.

He snapped back to reality and regained his composure. "Alright, I’ll arrange for maintenance operations right away. If we can get at least 20 units running, we should be able to complete all the repairs in under an hour!"

Lin Xian nodded and, without wasting words, immediately began working on the next unit.
