🏭 AIC Progression Guide: Build the Factory That Builds Your Account

AIC is one of those systems that feels “extra” until you realize it quietly controls how fast you gear, how stable your power is, and how easily you can fund expansions. The players who progress smoothly aren’t doing more—they’re doing the right production lines at the right time, then scaling them only when their mining and power can actually support it.

This update-style progression changes what “efficient farming” means: instead of grinding one best stage forever, your best progress comes from stacking systems—mining node control, stable plant loops, trade goods, batteries, and modular production lines—so every hour of play multiplies your output instead of bottlenecking it.

🧭 The Breakpoints That Decide Your Whole Factory Plan

Valley IV progression windows (your “swap points”)

  • Early game: Start → until you can mine Ferrium (around Authority Lv. 18)

  • Mid game: Ferrium online → until you can grind Cryston / Power Plateau access (around Authority Lv. 34)

  • Late game: Authority 34+ → Sandleaf era + multi-step endgame lines

  • Wuling: New facility constraints, new staples, new trade goods

Your top 3 factory KPIs (if these are wrong, everything feels bad)

  1. Ore consistency (node coverage + purity)

  2. Power headroom (Thermal Banks + battery pipeline)

  3. Routing freedom (Depot Bus + Protocol Stash so lines don’t choke)

✅ Valley IV Early Game (Pre-Ferrium): What to Build First and Why

The early-game rule

You’re not “building a base.” You’re building a foothold:

  • One line for early gear progression

  • One line for Stock Bills

  • One line for stockpiling the parts that future recipes demand

Priority items (and what they actually unlock)

1) Amethyst Component (your early gear backbone)

  • Purpose: early gear crafting so exploration doesn’t stall

  • Hidden value: it prevents the common early trap where you’re “progressing story” but undergeared for quarry enemies and detours

Recipe focus (the idea, not the spreadsheet):

  • Keep your Amethyst Fiber and Origocrust flow stable so the line runs continuously

  • This is a “must-run” line, not a “burst craft” line

Blueprint code (Asia): EFO01ouiO4aa58639IieO

2) Buck Capsule C (your early Stock Bills engine)

  • Purpose: trade good + early sustain

  • Hidden value: it’s what funds your factory expansion and routing upgrades faster than passive trickles

This line has two phases:

  1. Infinite Buckflower Powder loop

  2. Merge Buckflower Powder into your filling process (with bottles) to finalize capsules

Infinite loop farm blueprint (Asia): EFO012O9A7uuU48aeIOo
Buck Capsule C merge blueprint (Asia): EFO01iUIa6551e2e272U4

3) Amethyst Part (your “future-proof” stockpile)

  • Purpose: machines and later recipes constantly ask for it

  • Hidden value: it reduces “sudden stops” later when you unlock something new and realize you don’t have the basic part chain ready

Blueprint code (Asia): EFO0101O3o7789i7E979

đŸ§± Early Valley IV Layout Planning: How to Avoid Spaghetti

The layout shape that scales cleanly

Build your base like three lanes:

  • Lane A: Core production (Amethyst Component)

  • Lane B: Plant loop module (Buckflower loop)

  • Lane C: Merge + output (Filling / capsule finishing + depot output)

Keep each lane compact and copyable. If you have to “trace” pipes and belts with your eyes, you’ve already lost future scaling.

The biggest early mistake (and how to fix it)

Mistake: trying to run too many lines off limited Amethyst
Fix: cap your active lines to the 2–3 priorities above, and only add “nice-to-haves” when mining coverage increases.

⛏ Early Game Mining: The Fastest Way to Double Output

Take over Mineral Beds like it’s your main quest

Mining nodes are your factory’s income.

  • Every node you don’t capture is production you’ll never get back.

  • Don’t wait until you “need” the material—rig it when you pass it.

Purity is the silent multiplier

Higher purity isn’t just “more ore.” It’s:

  • faster crafting cycles

  • fewer idle machines

  • fewer clogged lines from uneven flows

That’s why Regional Development matters later—purity is what turns your factory from “functional” to “smooth.”

⚡ Early Power: Thermal Banks Without Eating Your Whole Economy

The early power rule

Use Originium first for Thermal Banks.

  • Batteries in early Valley IV compete with your Amethyst bottleneck.

  • Originium is easier to scale via mining coverage.

Two practical layouts you can drop in when power starts choking:

  • Manifold layout (Asia): EFO01ouiO4aa5860IieO

  • Load Balanced layout (Asia): EFO01Ue3608e87OEA7Oa8

Power checkpoint

If you’re constantly turning machines off to keep the grid alive, you’re not “short on power”—you’re short on:

  • Thermal Bank fueling consistency

  • battery transition planning (mid game)

  • or simply mining coverage

✅ Valley IV Mid Game (Ferrium Online): Your First Real Scaling Phase

Your mid-game pivot (what changes immediately)

Once Ferrium is available, your early priorities stop being “best” because:

  • gear tier jumps

  • trade goods improve

  • batteries become efficient enough to standardize power

Mid-game priority items

1) Ferrium Component (mid-game gear crafting)

  • Purpose: craft Level 36 Blue rarity gear

  • Scaling rule: duplicate the line when you unlock more Ferrium nodes instead of overengineering one huge line

Blueprint codes:

  • Asia: EFO019aEu8UU36eu5UI2

  • USA: EFO01eE7O6A33a4ioAi8

2) LC Valley Battery (your “stable grid” upgrade)

  • Purpose: efficient Thermal Bank fuel

  • Scaling trick: one packaging line can feed multiple Thermal Banks if you route output smartly

Blueprint codes:

  • Asia: EFO01O4a7i88eEI3i9oe4

  • USA: EFO0189304IUUO1eUI73

3) Buck Capsule B (better trade good + better healing)

  • Purpose: preferred trade good at stronger outpost levels + stronger sustain item

  • Setup concept: two bottle lines + one powder line → merge into filling

Blueprint codes:

  • Asia: EFO017i89aEE0U55EO0Ai

  • USA: EFO01O3E8A499eIi9oe4

The mid-game plant loop module (make it stackable)

You’re going to expand. Your farm needs to expand with you.

  • Asia: EFO0101O3o7789i0E179

  • USA: EFO01eE7O6A33a4AoAi8

🧰 Mid Game Factory Systems: The Upgrades That Change Everything

Factory expansion: why it matters now

Mid game is where “PAC port reliance” starts to break your speed.
You want:

  • more space

  • the ability to run parallel lines

  • the routing tools that make modular builds possible

Depot Bus + Protocol Stash: the “no choke points” upgrade

This is the moment your factory becomes a network:

  • You don’t need every line to touch the PAC directly.

  • You can split production into modules and centralize storage/output.

  • You can stop building awkward “bridge belts” just to reach ports.

Practical mid-game scaling rule

If your line stalls, it’s usually one of these:

  • your input node isn’t mined consistently

  • your plant loop isn’t truly self-sustaining at the volume you’re asking

  • your outputs aren’t dumped to storage fast enough (clog)

Fix the cause, not the symptom.

✅ Valley IV Late Game (Authority 34+): Sandleaf Era and Modular Factories

Late-game reality check

Late game isn’t “one bigger line.”
It’s several smaller lines feeding one final combine, because recipes now:

  • have more steps

  • have more streams

  • punish clogging

Step 1: Lock Sandleaf Powder production

Sandleaf Powder becomes the backbone of late Valley IV.
If it’s not stable, you’ll constantly stop-and-start everything else.

Anti-clog rule: use all shredder outputs and route them cleanly into storage/module feeds.
Scaling rule: build Sandleaf like a utility grid—oversupply is good.

Step 2: After Sandleaf, prioritize these three

1) Cryston Components (Level 50 Purple gear)

  • Concept: two ingredient chains → final combine

  • Rule: build each ingredient chain as its own module, then combine at the end

  • Efficiency tip: if the final unit starves, your modules aren’t balanced—duplicate the starving side

2) Buck Capsule A (strong trade + strong sustain)

This is where people clog constantly unless they build it like a merge:

  • Ground Buckflower Powder module

  • Steel Bottle module

  • Final fill merge

Anti-waste rule: feed two inputs of each side into the final fill so the unit doesn’t idle waiting on one stream.

3) SC Valley Battery (your power “endgame”)

This is the “flip the switch” upgrade for power:

  • replaces LC Valley Batteries

  • provides substantially better power per cycle

Routing tip: one packaging output can feed up to four Thermal Banks—late game is where that kind of routing matters a lot.

📈 Late Game Scaling: Regional Development and Purity as a Production Multiplier

Why Regional Development becomes mandatory

In late Valley IV, you’re not capped by “what you can craft.”
You’re capped by how fast your inputs arrive.

Higher Regional Development:

  • increases node purity

  • unlocks additional nodes

  • makes your modules run continuously instead of “burst crafting”

The late-game comfort target

When you stop having to babysit power and inputs:

  • your factory can run while you explore

  • you can batch-craft explosives or gear mats without dismantling lines

  • your depot actually fills instead of stalling at 50% uptime

✅ Wuling Starter Factory: New Staples, New Constraints, New Routing

Wuling priority items (what actually matters first)

  1. Xiranite (core ingredient for Wuling crafting ecosystem)

  2. Xiranite Components (high-tier gear crafting material)

  3. LC Wuling Batteries (Wuling’s stable power source)

  4. Yazhen Syringe C (recommended trade good early)

The Wuling rule: split lines immediately

Wuling recipes are complex and your space/tooling is tighter early.

  • Build modules (carbon/stabilized, powder, water/fluid steps, etc.)

  • Merge only at the final unit

  • Route to storage so outputs never clog

Facility constraint planning

If a facility is globally limited, treat it like a “slot.”
Decide whether it serves:

  • battery line stability

  • component line stability

  • or a trade loop that funds upgrades

If you try to serve everything at once, you’ll run everything at half efficiency.

Wuling early sequence that feels best

  1. Push story until the first outpost unlock opens the map and reveals your node plan

  2. Rig mining nodes immediately (Wuling is an economy reset if you delay)

  3. Unlock and place the Wuling Depot Bus early (routing freedom matters more here than Valley IV)

  4. Raise Regional Development so purity climbs and your modules stop starving
