Apocalypse: I Built the Infinite Train

"Subject 03: Iris-like Star Ring

Captured by the Harper Space Eye before its crash. Angel Project theorizes it to be an interstellar entity lurking within dark matter clouds. However, due to lack of substantial evidence, it has not been classified under Eerie Entity Phenomena for now. Awaiting further observations, number retained."

"Subject 04: Unknown Deep Pacific Abyssal Creature

First discovered on July 11, 2069, in the Pacific Ocean and the Black Ocean Abyss. Exact morphology remains unknown. Observed size exceeds 13 kilometers. Previously triggered the Bor Island Tsunami…"**

"M-Mom… why the hell are these things appearing on Blue Planet?"

Staring at the Phoenix Organization’s Eerie Entity Index, Shasha’s eyes seemed to lose their spark. She muttered in disbelief.

Chen Sixuan sighed. "These things… they seem even more hopeless than zombies or the darkness itself."

The sheer scale of what they were looking at stunned everyone. Even Fire Bro, usually loud and arrogant, had nothing to say—his mouth opened and closed, but no sound came out. The only one who remained indifferent was Ding Junyi.

To her, fear of death was all the same. Whether it was an Abyssal Monster or a zombie—both simply represented the destruction of flesh. Her strictly materialist, scientific view left her unfazed.

Seeing the gloom settle over the group, Lin Xian finally spoke up.

"We just survived another brush with death. As long as humanity isn’t completely wiped out—there’s still hope."

His words lifted some of the heavy weight in the room.

Chen Sixuan nodded. "Yeah. After all, humans have built cities in the sky weighing millions of tons, and weapons with destructive power in the billions of tons. We still have a chance against these things."

Seated in a swivel chair, KIKI flipped through the eerie entity index with her eyes darting rapidly over the data. Suddenly, she let out a surprised "Huh?"

"Not every eerie entity produces Eerie Blood Crystals?!"

Her remark caught everyone’s attention.

Ding Junyi adjusted her glasses and leaned in to look at the entry:

"Analysis of over 1,000 cases of C-class and B-class eerie entities by the Nightwalkers Organization confirms that the production and concentration of Eerie Blood Crystals is directly proportional to the number of humans an entity has killed…"

"So it’s confirmed. Blood Crystals… are human blood."

Ding Junyi’s expression turned icy. Taking a deep breath, she continued, "I had a theory about the Foundation Laboratory on the 7th floor—that it was experimenting on humans, turning them into a ‘filtration system’ for harvesting dark energy. The goal? Feeding eerie entities to mass-produce blood crystals."

The room fell deathly silent.

Chen Sixuan covered her mouth in shock. The others visibly paled.

"You’re kidding, right?!?" KIKI’s eyes widened in horror.

Lin Xian’s brows furrowed deeply. "You mean… the stronger the Ability User or Evolver, the higher-grade Blood Crystal they produce if devoured?"

The implications were monstrous—raising humans as livestock to harvest Blood Crystals. This wasn’t just anti-human… it was something far worse.

But as soon as he finished speaking, he noticed everyone staring at him.

Ding Junyi stuffed her hands into her coat pockets and gave Lin Xian a knowing look. "I was just making a deduction from the data… but your thinking is even more terrifying than mine."

Lin Xian was speechless. I was just following your logic!

Abilities and Power Scaling

"Alright, let’s move on to what everyone’s most interested in."

KIKI stole a glance at Lin Xian before pulling up the third section of Fire Book's Data Package—the topic everyone had been waiting for.

Abilities.

Until now, their understanding of abilities came from KIKI's early access to Angel Project’s data. Lin Xian only knew that several members of their group had reached Evolution Level, but nobody had a full grasp of the details.

Among them, only Fire Bro had actively worked on developing new ability techniques. KIKI and Big Luo, on the other hand, had brute-forced their way through growth—completely lacking any structured training.

Fire Bro’s approach wasn’t much better. His abilities were developed through trial and error, and his "naming" of skills was nothing more than self-indulgence.

Aside from combat experience, the only confirmed ways to improve abilities were Hell’s Black Chrysanthemum transformation energy and… that was about it.

Section 3: Abilities

According to the latest Phoenix-Nightwalkers Report, over 100 distinct ability types had been identified and categorized into ten major classifications.

Abilities were ranked from S, A, B, C, D based on their uniqueness, potential, and threat level.

• D-Class: The most common abilities, including Flesh Proliferation, Limb Mimicry, Gigantism.

• C-Class: More advanced types, like Beast Form, Blood Qi, Undead Regeneration, Water Affinity, Metallic Skin.

• Big Luo was classified under Blood Qi, meaning his strength and regeneration increased with blood loss—but at the cost of massive strain on his heart, lungs, and spine.

• B-Class: Rarer abilities, including Demonic Form, Earth Manipulation, Cursed Bones, Monstrous Eyes.

• All flight-based abilities were categorized under B-Class.

• A-Class: Wind, Water, Superbody, Resonance, Sonic, Laser, Psychic, Superspeed, Telekinesis.

• Jiang Yun had Wind,

• Li Guangwen (Chasing Sun Convoy) had Resonance,

• A’Bai had Laser,

• Qian Dele had Superspeed.

• S-Class: The most powerful tier. Psychic, Fire, Lightning, Light were expected. But one ability stood out.

"Evil Desire."

Lin Xian froze.

They had encountered this before.

The Green-Haired Woman from the Black Crow Four, the one who controlled zombie hordes at Hengshan Pass—she had this ability.

"Whoa, that woman was S-Class?!"

KIKI was stunned.

"Controlling zombie tides is an immense threat," Shu Qin noted. "She nearly wiped out our entire convoy single-handedly. Imagine if she got stronger."

Lin Xian and Chen Sixuan both nodded, recalling that nightmarish encounter.

If her ability had room to evolve, the consequences would be catastrophic.

"But we have two S-Class Ability Users on our train."

Shasha playfully glanced at Lu Xingchen.

"Fire Bro, you’re an S-Class. Got any thoughts?"

"Hmph!"

Lu Xingchen snorted. "I am the incarnate of the Fire God. I do not concern myself with petty rankings."

But he couldn’t help adding, "However… I do approve of them placing Fire ahead of Wind, Lightning, and Light."

"Yet you’re still ranked below me~" KIKI teased.

Lu Xingchen waved dismissively. "They probably sorted it alphabetically. Doesn’t count."

Big Luo frowned. "Wait… that actually makes sense."

"Bullsh*t!" Shasha smacked him. "Then why is Light not listed before Fire?"

Everyone laughed.

But Chen Sixuan quickly brought them back on track.

"Enough arguing. This isn’t about rankings. Focus on how to actually upgrade abilities."

Her teacher-like tone immediately silenced them.

Lin Xian sighed, rubbing his forehead.

He noticed his Mechanical Ability wasn’t listed—neither was Ding Junyi’s Plant Ability.

This made him realize—no wonder Phoenix Organization was so interested in him. His ability was rarer than Psychic Power.

And if there were other Psychic Ability Users, KIKI wasn’t the only one.

Lin Xian thought for a moment before shaking his head. "Trying it isn’t a bad idea, but since Xilan City’s Nightwalkers Organization has equipment for testing Ability Users, I think it’d be better to wait until we understand more before using it. At the very least, we’ll know how it affects our abilities. Right now, if we drink it, we’re just guessing."

"That makes sense~" KIKI agreed. "I want to see if I’ve already broken through to the Diamond Rank."

Hearing this, Lu Xingchen instantly snapped awake. "Interesting. I, too, find it absolutely necessary to test this."

Lin Xian chuckled helplessly. He wasn’t too worried about his Mechanical Heart since it had a structured growth progression. What really piqued his curiosity was the potential new skill rewards he might receive.

At this moment, he was immensely grateful for taking the risk in Clearwater Town and devouring that nuclear-powered turbine engine in the middle of the night. Gravity Lens had already saved his life three times. Though it drained his energy, in hindsight, it had been a bargain.

Charging Through the Storm

Whoosh! Whoosh! Whoosh!

The United Train Convoy plowed through the blizzard, racing through the dark night.

The Rescue Convoy, the Emperor Project Team, and the Investigation Corps from Xilan City—hundreds of armored vehicles forming an unstoppable tide of steel, crushing the snow beneath their wheels as they pushed forward to Xilan City.

Lin Xian had rested for a few hours, recovering a significant amount of energy. Seizing the downtime, he manufactured additional ammunition to prepare for any unexpected crises.

However, not long after, thunderous explosions rumbled across the blizzard-stricken landscape.

Boom! Boom! Boom!

A dense barrage of artillery fire erupted in the distance, jolting awake many passengers who had been sleeping inside the United Train Convoy.

Instinctively, they grabbed their weapons—survival had been engraved into their very DNA. In this world, there was no distinction between day and night—only between life and death.

Incoming Communication

"To all survivor convoys, Dragon Mountain No. 1, and Infinite Train—this is Commander He Zhen of the Seventh Investigation Corps. We are approaching Xilan City. Scout reports confirm the city is currently under attack by Eerie Entities—threat level: Moderate. However, we have support firepower clearing a path. No need to panic—we’re going straight into the city!"

Commander He Zhen’s voice carried a firm, commanding presence, invigorating everyone who heard it. His tone suggested that Xilan City’s defense forces were well-versed in handling these Night Horrors, which helped ease the tension in the convoy.

Xilan City – A Fortress That Still Stands

"Looks like Xilan City is operating on a Fortress Defense Strategy—meaning the entire inner city is likely still secure."

On Infinite Train, Shu Qin’s voice was filled with surprise upon hearing Commander He Zhen’s transmission.

"Seems like it."

Lin Xian’s spirit lifted.

Throughout their journey, they had never encountered a city that hadn’t already been overrun by Zombies or Eerie Entities.

No wonder Nightwalker Courier Zhou Wuer had insisted on meeting them in the city. It seemed that, under the Phoenix Organization’s protection, Xilan City had somehow maintained a functioning urban infrastructure.

"I remember my father mentioning Xilan City once," Chen Sixuan added. "Originally, it was an industrial city built over an iron ore deposit. Small, but equipped with nuclear-tier city defenses. Before the Federation was founded, this place was meant to be a northwestern defense stronghold for Longguo.

"More importantly, it controls multiple key oil and natural gas transportation hubs—making it a strategic stronghold. This city even has full-fledged production lines for heavy tanks and mechas."

A City Built for War

With a lollipop in her mouth, KIKI tapped away at her computer keyboard. In moments, she pulled up a schematic of the city.

"This city isn’t huge, but it was built into the mountains. Fenglan Mountain isn’t that tall—only about 1,000 meters—but it’s the largest peak in this entire grassland-desert region.

"Tsk tsk~ And look at this! The city still has a military defense wall!"

"That wall was built last century…"

"Oh, and check this out—Duggar Radar Array. It’s an old relic from last century too, but it has a ten-megawatt power output. If they activate it, every radar system in the entire Yunjiang Plains will experience interference. But nowadays, it’s just a tourist attraction."

"I remember before Apocalypse Day, this place had a ton of heavy industry but barely any population. No one really came here for tourism."

The Iron Fortress Emerges

"LOOK!"

On Infinite Train’s tactical observation system, the image resolution gradually sharpened.

A towering mountain silhouette emerged in the distance.

As the snowstorm weakened, visibility improved, revealing a city of pure steel and concrete—an unshakable industrial fortress.

From all directions, waves of Snow Wraiths surged toward the city, but they weren’t attacking the convoy—they were charging straight at Xilan City.

The city’s massive military walls stood firm. Heavy artillery rained down from the fortifications, filling the night with the thunder of explosions and gunfire.

On the snow-covered mountaintops, radar towers and searchlights illuminated the battlefield, casting an overwhelming aura of dominance over the city below.

The Final Approach

The United Train Convoy’s first checkpoint was a massive oil refinery just outside the city.

Giant pipelines crisscrossed the snow-covered land like the veins of the Earth. Amidst these industrial structures, Snow Wraiths and Eerie Entities rampaged—some already rushing toward the convoy.

BOOM!

The Investigation Corps’ support forces opened fire.

Hellfire Barrage

BOOM! BOOM! BOOM!

A colossal explosion rocked the monster horde, detonating in the distance like divine thunder.

A giant thermobaric bomb ignited kilometers ahead, forming a white-hot shockwave dome that expanded outward—crashing into the convoy with enough force to tilt every vehicle sideways.

For a split second, everyone experienced deafening eardrum shock.

"It’s just our support artillery and airstrike units—don’t panic!"

"We’re almost inside the city!"

Xilan’s Ultimate Fortress Defense

From the city walls, dozens of large-caliber railguns fired in synchronized volleys, tearing into the charging Snow Wraith hordes and setting off chain-reaction explosions.

The city’s defense network was unparalleled.

• Great Wall-50 Railgun Batteries

• Iron Curtain Anti-Air Defense System (a mix of missiles, electromagnetic cannons, and CIWS turrets)

• Hundreds of heavy firepower turrets

• **An elite battalion from the Starfleet Investigation Corps

• Xilan City’s unique mountainous terrain

Together, they formed an impregnable stronghold.

Under the cover of this immense firepower, the United Train Convoy pushed forward, crossing into Xilan’s outer industrial zone.

The howling Snow Wraith horde disappeared behind them.

As the storm calmed, a city hidden beneath the mountains revealed itself.

The Final Countdown

"Two days left… Let’s hope everything goes smoothly." Lin Xian muttered, watching the fortress city glow in the fading blizzard.
