System: My Doomsday Train Chapter 978 - 366: Rough Civilization

"Promotion Conditions": Possess three Civilization Wonders, a territory spanning one billion light years, and the strongest attack energy range surpassing 300,000.

"ps: Starting from upgrades beyond Second-level Civilization, each promotion unleashes a ’Promotion Ripple’ that nearby civilizations can detect. Higher levels mean a broader reach for the ’Promotion Ripple’.

"Civilized Means": Murphy Stone Ore will naturally appear across the civilization’s territory.

-

Methods for a Level 6 Civilization remain incredibly straightforward.

Assist the civilization in gathering more Murphy Stone.

Theoretically speaking.

Greater territory coverage leads to increased production of Murphy Stone Ore.

Take this example...

Should the "Nia Star System" fall inside the Cyan Mountain Civilization’s territory, Murphy Stone Ore might spawn there; otherwise, no possibility exists.

A remarkably straightforward civilized means.

When judging solely by civilized means, Level 6 Civilization methods rank as fairly ordinary, falling short of even Fifth-level Civilization ones.

Fifth-level Civilization methods conserved vast amounts of his resources.

"Resource costs for upgrading all train accessories inside the civilization drop by half, excluding defensive items such as ’Armor’ and ’Energy Shield’. Murphy Stone usage stays the same."

This particular method...

"Hold on."

Chen Mang abruptly wrinkled his forehead. Amid his recent frenzy, he overlooked this detail until now—upgrading accessories lately hadn’t shown halved resource costs.

Take his recent upgrade of the "Train Assistance AI" from level 2000 to 5000: it demanded 5 foundation units of iron ore, the full amount. Halved, that would mean just 2.5 foundation units.

Yet moments later—

A small red indicator appeared on the train control panel.

Tapping it revealed a notification panel.

"Backup hidden resources: 4.127 foundation units of iron ore accumulated."

"Withdraw them anytime."

"Ah, I see..."

Chen Mang nodded in realization. Apparently, the halving doesn’t apply upfront during upgrades; you spend the full amount first, then receive half back as a refund.

On the surface, it seems identical, yet a key difference exists.

Upgrades require possessing the complete resources beforehand for the refund to trigger—no skipping ahead without them.

...

The conflict against the Cyan Mountain Civilization drew to a close.

Now came the scavenging stage.

The Constant Star Train roamed relentlessly through the six remaining star systems of the "Cyan Mountain Civilization", absorbing military base databases into the train AI’s storage and hauling intact mining stars aboard.

Damaged mining stars received swarms of mining robots for rapid extraction, while minor resource deposits on planets like sentinels got scooped up too.

Even scraps count as gains.

Legitimate mining for these bits would drag on forever.

Cleanup proved quite time-intensive.

An entire month elapsed.

Chen Mang at last wrapped up the Cyan Mountain Civilization purge. These six star systems would splinter into separate low-level civilizations, evolving gradually in the cosmos—none of which concerned him anymore. True civilization growth demands eons.

Across tens of thousands of years, scant progress might occur.

Therefore.

Total victory achieved.

This war fully concluded.

After all deductions, pure profit stood at 2872 foundation units of iron ore!

One foundation unit equals 10 trillion units of iron ore!

A single foundation unit rivals the full haul of an "Extremely Evil Civilization".

Annihilating the Cyan Mountain Civilization matched wiping out 2872 Extremely Evil Civilizations.

Slaying 2872 Satans.

Satan remained pathetically resource-poor.

What a squandered title.

Lounging in the train chamber, Chen Mang reviewed this bounty’s tally while checking Seventh-level Civilization upgrade requirements.

-

"Promotion Conditions": Possess three Civilization Wonders, a territory spanning one billion light years, and the strongest attack energy range surpassing 300,000.

-

Surpassing 300,000 in strongest attack energy range.

Straightforward enough.

A mere 3000-level Akanon Light Energy Main Cannon suffices; 5000 levels pose no issue either—especially now, with boundless wealth at his command!

Securing three Civilization Wonders presents the real hurdle.

Currently, only "Insect Silence" and "Divine Silence" grace his collection as Civilization Wonders.

Though the "Nia Star System" got flattened into a plane by Cyan Mountain Civilization’s Two-dimensional Foil, its Civilization Wonders endured unscathed—utterly impervious to dimensional collapse.

However...

Civilization Wonders emerge purely by chance and luck, with no set path; the third one’s arrival remains unpredictable.

Territory spanning one billion light years.

Not overly demanding.

Draw territory boundaries freely, expanding as desired, provided no equal or superior civilizations occupy the space.

Eradicate any Seventh-level Civilization there, and claim it all.

In essence.

Advancing to 7th-level Civilization demands.

First, crush that local Seventh-level Civilization, plus... secure another Civilization Wonder somehow.

"Sigh..."

Chen Mang let out a helpless sigh. Others’ paths remained unknown, but his upgrades skipped same-level foes entirely—pure cross-level carnage.

Fourth-level versus Fifth-level, Fifth against Sixth, now Sixth tackling Seventh-level Civilization.

Do all civilizations face this?

The dominant Seventh-level Civilization here bears the name "Rough Civilization".

Such a title hints at a rugged, obstacle-filled history.

Ai tirelessly gathered data from all fallen AIs within a billion light years, uncovering details on the "Rough Civilization".

"Train Captain."

Ai’s voice filled the train chamber.

"From the Cyan Mountain Civilization database plus recent collections, I’ve assembled all available intel on Rough Civilization."

"It’s governed by the ’Star Arrow Race’."

"Unlike ’Train Civilization form’, though some trains and accessories aid it, the core structure is ’Body Refinement Civilization’, akin to cultivation civilizations, centered on personal might."

"Power builds up for battle."

"A top warrior can demolish star systems in one blow."

"Tremendously formidable."

"Oh?"

Chen Mang’s expression turned peculiar. Star Arrow Race rang a rare bell—not widely known, yet familiar to him.

Pure coincidence.

Days back, munching 500-level bread slices randomly gifted him a Star Arrow Race talent: elite archery prowess.

Useless to him so far.

"Does this race rely on bows and arrows as primary weapons?"

"No."

Ai’s tone lingered softly in the chamber.

"This race stands out uniquely; every individual qualifies as a ’Chosen One’, awakening innate powers to become either ’Berserker’ or ’Divine Archer’."

"Historically, the two types balanced evenly."

"But eventually."

"The ’Divine Archers’ in ’Rough Civilization’ dwindled sharply, ceasing to appear altogether. Today, the ’Holy Archer’ role sits entirely empty."

"No one claims ’Holy Archer’ status."

"Traditionally, the paramount ’Divine Archer’—the ’Holy Archer’—leads as civilization head, steering its destiny. Without one, Rough Civilization lacks true direction, clinging together via Elder Council decrees, yet fractured and disunited."

"That’s why Cyan Mountain Civilization endured."

"Otherwise..."

"A Level 6 Civilization like Cyan Mountain would’ve faced swift extinction—far too dangerous to ignore."

"Per Cyan Mountain Civilization records, they once launched a covert operation dubbed ’God Extinction’."
