Doomsday: I Build an Infinite Train.

Chapter 469 Mech Upgrade Plan
[Successfully devoured. Mechanical Source Points +1100, Devouring Proficiency +230]

Wow!

Under the night sky at Oahu Airport, a large wide-body passenger plane, along with its broken wing, was reduced to ashes. Various organic materials, including human corpses, fell to the ground with a clatter. The noise startled many nearby zombies, who were now twisting their rusty joints, making eerie creaking sounds as they moved quickly through the darkness. Their hoarse roars came in waves, but after getting close to the source of the sound, they lost their target again, their green, decaying eyes searching around.

Lin Xian stood on a drone, hovering quietly in the air. Looking at the light screen in front of him, his eyes were full of excitement.

"This is the first time it has swallowed a passenger plane. Although the fuselage was damaged, the engines and avionics systems were still intact, and it actually converted more than a thousand mechanical source points..."

[Current Mechanical Heart Level: LV.6 (40900/50000)]

[Mechanical Awakening]: Mechanical Lord
Mechanical Devouring: 6 (3130/5000) Increases devouring efficiency

Mechanical Manufacturing: 6 (1560/5000) Improve construction efficiency

Looking at the panel of Mechanical Heart, Lin Xian took a deep breath: "A quick search tonight should be enough. At worst, I can rest tomorrow..."

With no looming crisis looming overhead, Lin Xian was determined to seize this opportunity. The [Energy Leap] he gained after this amplification, along with the legendary [Supercritical Diffraction Sword] skill he acquired from devouring the Fearless-class, proved invaluable on Sea Rock Island. As the situation for humanity grew increasingly dire, focusing on unlocking the potential of his mechanical abilities was undoubtedly a wise choice.

Lin Xian made up his mind and began to devour the other two narrow-body passenger planes and the transport ship, not even sparing the crashed aircraft.

In addition to devouring mechanical source points, he also needs to collect more advanced materials for the construction sequence to unfold in the Black Star Forge.

Currently, Lin Xian will keep all six construction sequences running unless there is a crisis or during battle. There is still a large gap in what he needs to build, and he needs more functional drones to help him build, repair, transport, and maintain the equipment. Lin Xian is also preparing to build a mecha army.

This army is not just using attack drones for swarm attacks, but real combat mechs like those of Qian Su Xun. Lin has already built four 'Steel Bone' series mechs for Luo Yang to experiment with, and the results are quite good.

This unexpected acquisition of a military train belonging to the Federation Interstellar Army's 974th Defense Regiment, along with the mech combat group on board, gave Lin Xian a new idea.

Humanity's interstellar combat mechs were once centered around humans; the exoskeletons and mechs were all devices that served humans. Apart from service robots, only drones possessed the capability for swarm attacks.

However, there is a very critical problem with current human technology: drones, including the Thunder Falcon 2000, are somewhat weak in attack against large-scale monsters. Although swarming would increase the benefits, the monsters that have evolved in the darkness now possess bio-force fields and energy attack capabilities. Combined with the information suppression capabilities brought about by the dark invasion, it is difficult for these attack drones designed before the Apocalypse to have a very high ceiling.

Lin Xian's drones are now half manufactured by him and half 'seized' from Qin Feng in Dawn City. Although they have played a significant role in various aspects of his journey, from land to sea, they have not met Lin Xian's requirement of being able to directly disintegrate and eliminate the strange entities with a massive force.

Therefore, he plans to redesign a drone mech specifically for dealing with the strange entities. It will not require human operation, will have strong defense, both soft and hard kill capabilities, and will also have a distributed communication architecture and anti-interference technology that combines dark energy. In this way, Lin Xian can mass-produce it like a cloned army, gradually forming an iron legion that can pose a threat to even the special and S-class entities.

Currently, Lin Xian only possesses the blueprints for Qian Su Xun's "Steel Bones" and "ACS". Apart from that, he only has the blueprint for "Dancer 1" from the previous Crimson World. The Star Force's Vulcan, Guardian, and other series are all driven by humans. Even if remote control components are temporarily added, it is only a temporary measure and cannot be used in the long run.

Lin Xian had discussed this with Shinji Mochizuki, and Yu Yuheng from the Monarch Project had also briefly inquired about it. In this regard, the Monarch Project actually had two development paths: one was the super-large human weapon - Pangu, and the other was the steel bee swarm.

However, Yu Yuheng was not clear about this steel beehive project, and no actual machine had been manufactured. Therefore, all things considered, Lin Xian could only combine his own ideas to make one.

[Successfully devoured. Mechanical Source Points +260, Devouring Proficiency +40]

Lin Xian completely devoured a narrow-body passenger plane that had broken into two pieces. Looking at the light screen, Lin Xian contacted Viola.

"Viola."

【I am here. 】

"You're saying that if I build a batch of Cyborg and Iron Hunter-class power armor with their flight control systems combined, and then build another batch of Dancer 1 and Shadow Wolf-class power armor with their fire control units matched and combined, wouldn't that be an upgraded version of Cyborg and Reaper?"

Viola, through Lin Xian's power armor, remotely projected a holographic interface, displaying a scene of the two power armors merging with the smooth form of Dancer 1, and then whispered in his ear...
This is a very crude design, which will result in a waste of at least 5.3% to 17% of the pre-designed functional units and manufacturing materials, as well as incomplete compatibility with the main frame. Compared to the integration of 'Cyborg', it will lose some overall defensive capabilities. However, Dancer 1's artificial torso can perfectly match the power armor's cockpit, which is equivalent to enhancing Dancer 1 with a bio-armor. While possessing high flexibility and high intelligence, it will also have the defense, weaponization, and power component upgrades of power armor, making it superior to 'Cyborg' and 'ACS' in terms of overall strength.

Lin Xian's lips curled slightly: "This is exactly what I want. Can material waste be avoided?"

hum~
The blueprint of the holographic interface began to change, and Viola began to calculate Lin Xian's problem. At this time, a series of built-in systems were dismantled.

[I have removed the internal life support systems of the power armor, including oxygen, heating, biological rescue, and overheat protection, and added a distributed communication architecture self-organizing network system. However, this system needs to be redesigned and added. In addition, the external flexible defensive skin of Dancer 1 can also be removed to reduce the investment in super-solid carbon condensed matter alloy materials, or this material can be upgraded to the inner layer of the external power armor defense to create a composite architecture.]

"NICE!"

Lin Xian's eyes lit up as he listened, and he became more and more interested: "Although it's a bit rough, the combination of the two can still be considered a new intelligent mecha. There are always more solutions than problems."

[If we're going to design them as 'Steel Bones' and 'Reapers,' I suggest adding the array shields of the 'Iron Curtain' drones, the magnetic storm system of the 'Thunder Prison,' and the electrostatic field system to 'Steel Bones' to increase their defense and impact. Add the VK electric knife combined with a high-energy plasma wire cutter to the 'Reaper' series. This might increase their size, but firstly, it would integrate with the existing blueprint system, and secondly, it would enhance the mech legion's coordinated combat capabilities. With this level of impact, reaching 100 units would be enough to relatively easily crush A-class and special-class mechs; reaching 1000 units should be enough to cut off one-third of the canopy of the atmospheric mica we encountered yesterday for internal research and as food for human consumption.]

"..."

Lin Xian frowned: "No, is this the plan you just came up with?!"

Viola paused for a moment, then added, "[It might be somewhat cruel, and we also need to consider the energy level of the mech units...]"

"cruel?"

Lin Xian's eyes lit up, and he slapped his thigh, saying, "You're overthinking it! This is exactly what I want! I love it!" Although Viola couldn't generate a completely new mecha design for him on her own, the solution she provided, based on the known data, was exactly to his liking.

Mass-producing interstellar-class warframes might be difficult for Lin Xian right now, and it would be too wasteful, but manufacturing a full-coverage Shadow Wolf-class warframe plus Dancer One is still manageable!

"That's the decision. Immediately integrate the blueprint according to the idea we just had. I'll make a set first to test its quality."

Okay, may I ask what you would like to name these two newly integrated blueprints, or can they be referred to by their old codenames?

"let me see."

Lin Xian hissed and quickly opened the blueprints for the male Iron Hunter Power Armor and the female Ghost Wolf Power Armor. His eyes lit up immediately. Dancer 1 could almost perfectly match the Ghost Wolf female power armor combination, while Steelbone required extensive modifications to the Iron Hunter Power Armor due to its large size.

"The new Steelbone is renamed Iron Man, and Dancer 1 combined with the Ghost Wolf is renamed Dragon Girl. One male and one female, working together makes the job easier. From now on, the Iron Man mech will be responsible for ground suppression, frontal defense, and forming a suppression zone, while the Dragon Girl mech will be responsible for high-speed aerial attacks, dismantling and cutting."

Thinking of this, Lin Xian suddenly had a new idea: "Right, the interstellar military's power armor all have a synergy system. See if it can help me with tactical co-construction. For example, Iron Man can connect to the electromagnetic field, and Dragon Girl can combine plasma beams to form a powerful attack or something."

Viola understands.

"Great!"

Lin Xian became more and more excited as he thought about it. The design of the mecha army had finally broken through the construction of the drone swarm and a new idea had begun to emerge. Fortunately, he had Viola's computing power to help him integrate the blueprints. With the industrial manufacturing capabilities of his Black Star Forge, he was able to achieve the innovative ideas that even Xinghua Heavy Industry would need a large number of engineers to complete.

"Although it's a bit expensive, only something of this level can be used to fight against large-scale monsters."

Lin Xian murmured that mass-producing the Steel Bone, Dancer No. 1, and Ghost Wolf Iron Hunter power armor was no easy task. You see, when Lin Xian was in the snowfield, he spent an entire night making a Ghost Wolf-class power armor for Chen Sixuan to wear. That was already a life-saving artifact capable of dealing with large-scale monster tides. Now that Lin Xian was using it as an accessory for the mecha army, it was simply the epitome of luxury.

However, there's no other way. Low-level anomalies can be dealt with by superhumans alone. As for the super-large ones, Lin Xian thought that perhaps humanity can only rely on mecha armies or build super-large human weapons to fight against them.

"Materials, materials, there are so many materials that need to be converted now, we need to hurry."

Lin Xian thought of the Emperor Project and realized that he seemed to be developing along those two paths as well: creating a mecha legion. At the same time, he was also looking forward to upgrading the blueprint of the Interstellar Raider XR01 mecha to see if the 'planetary level' blueprint was indeed a product of Earth.

The night sky over the Hawaiian islands was dotted with stars, and the waves were calm. But tonight, this deserted place, which had been abandoned for months, was somewhat noisy. A swarm of drones flew overhead. After Lin Xian had completely devoured Oahu Airport, he began to move towards the city.

5 a.m.
In an abandoned amusement park in Vegas, Lin Xian had unknowingly devoured hundreds of cars in the parking lot. The wind carried the cool breath of the sea, and the silhouette of the broken Ferris wheel slanted into the fading night sky. A few remaining stars stubbornly hung in the velvety deep blue sky, twinkling. Outside the barbed wire fence, gray zombies wandered aimlessly, their low, hoarse roars like the friction of rusty door hinges, becoming the only dull background sound in this ruin.

Lin Xian sat atop the drop tower, a faint light flowing from his palm. He remotely softened and twisted the massive steel structure in the parking lot, as if it had been thrown into an invisible furnace and was rapidly swallowed up as ashes. Only a few imprints remained on the ground and a faint, almost imperceptible metallic smell in the air. A few meters away, the windshield of the last car still had dried palm leaves stuck to it. Affected by this invisible force of absorption, the leaves spun around and silently turned into fine ashes that fell to the ground.

"Roar……"

The barbed wire swayed incessantly, as if it had discovered its long-lost prey or as a primal instinct triggered by the darkness. Countless zombies clung to the barbed wire, roaring as they stared at the living person sitting on the drop tower.

Lin Xian didn't even lift his eyelids. He casually picked up a faded toy horn from a convertible sports car next to him whose roof had been torn off. He weighed the plastic thing in his hand and swung his arm around it.

Whoosh!
The orange horn whistled and whistled as it passed over the barbed wire fence. With a "smack," it struck a zombie precisely on the head, making a "quack" sound. The zombie seemed a little dazed by the insignificant impact, staggering back a step. Its cloudy eyes rolled around blankly for a moment, then it stubbornly moved forward again.

At the same time, the loud noise attracted a large number of zombies from the shadows, who then surrounded the zombie, creating chaos.

After sweeping through a large part of the city, Lin Xian discovered that there were only some C-level or D-level anomalies in the city, and no other threats. Perhaps the anomalies didn't even care about this island and headed towards the mainland where the human army was gathered, making this small island a place of temporary peace. With this conclusion, Lin Xian relaxed a bit and focused on devouring.

Seeing the zombies swarming together, tearing at each other, a barely perceptible smile flickered across Lin Xian's lips. His hands didn't stop moving; one, two, three... The steel torrent that once symbolized wealth and speed in the parking lot melted away at a visible speed in the dark red light flowing in his palm. The Black Star Forge seemed to be silently sucking in, each brief contact taking away a chunk of metal shell, turning it into the pure source of energy flowing through his mechanical heart, and adding weight to the massive forging plan.

Thousands of drones streaked across the sky, leaving faint trails of light, like diligent fireflies flitting over the bizarre and dazzling landmarks of the gambling city. The soft buzzing of their drones, controlled by Viola's immense computing power, continuously transported supplies from the city toward the Sky Train.

Creak~
A sudden, scraping sound of rust came from behind.

Lin Xian turned around abruptly, his gaze sweeping across the center of the abandoned amusement park. The dilapidated carousel pavilion swayed slightly in the wind, as if it had been gently pushed by invisible fingers. The rusty supports groaned, causing the several rickety painted wooden horse panels on top to tilt and twist. A cold wind swirled up, and the withered leaves on the ground spun and danced, mixed with a few faded amusement park posters and yellowed gift cards, rustling as they slid along the ground like the footprints of ghosts.

A series of crisp, abrupt pattering sounds came from beside me, like the rhythm of high heels stepping on cracked concrete.

Why would there be the sound of high heels at this time and in this place?

At this moment, from the shadows behind the carousel, a woman slowly emerged from the misty dust, her steps unhurried. Her black hair brushed against her pale cheeks in the wind, and her gray-black trench coat swayed in the breeze. She stopped at the edge of the carousel's shadow, slowly raised her head to look at Lin Xian, her eyes as calm as a still pond on a winter night.

"Long time no see, Lin Xian."

Lin Xian's eyes narrowed, he stopped what he was doing, and slowly stood up. His previously leisurely face now became serious.

The person in front of me was none other than the head of the SIID Foundation.

Hua Xiaoling!
