Wuling AIC Early Game: Bootstrap to Hetonite
Table of Contents

The fastest way to stall in Wuling is to wing it. The fastest way to leave the early game behind is to follow a phase order that gets your factory paying for itself before you ever touch a dungeon. This guide walks through the exact build order players use to bootstrap a Wuling AIC from a cold start through hetonite components — power first, then materials, then profit.


TL;DR - Key Points

  • Stockpile 5-10 stacks of 50 HC Valley Batteries before arriving in Wuling — this is your bootstrap fuel, not a long-term plan
  • Xiranite is the universal intermediate — carbon (from Wuling plants) + water, both renewable, infinite scaling with forge count
  • One battery packager fed with 3 belts of Dense Originium Powder + 1 belt of Xiranite powers every mining outpost you will build
  • Stockpile ~10k Xiranite Components, then pause — the buffer outlasts every early-game demand
  • Skip Qingbo Stockade if you can wait for Marker Stone — the xircon chain becomes cleaner with underground fluid routing and Expanded Crucibles
  • Heavy Xiranite and Hetonite are direct outpost cash — both sell well, both feed hetonite components
  • Two Expanded Crucibles replace five standard crucibles for xircon at Marker Stone — worth the wait

Phase 0 — The Bootstrap Charge

You cannot build a Xiranite line on no power, and Wuling does not gift you any. Before you set foot in Jingyu Valley, craft or buy 5-10 stacks of 50 HC Valley Batteries and dump them into your Wuling-bound storage. That stash gets your first miners and assemblers running long enough to start producing Wuling power locally.

This is a one-time tax. Do not over-engineer it — the goal is just enough runway to bootstrap.

Phase 1 — Foundational Self-Sufficiency

This is the make-or-break phase. Every loop you set up here should be infinitely sustainable so you can scale by tiling, not redesigning.

Step 1: Xiranite Farm

Xiranite is the universal intermediate that everything in Wuling eventually touches. The recipe is carbon + water, and both are renewable, so this farm runs forever. Output scales linearly with forge count.

InputSourceWhy
CarbonWuling plantsCompact footprint, space-efficient
WaterStandard pipingRenewable, no limit

Use Wuling plants for the carbon side — they take up far less space than alternatives, and space gets brutal once you start stacking battery and component lines.

Step 2: Sandleaf Farm + Dense Originium Powder Factory

Dense Originium Powder is the bottleneck that catches most new Wuling players off guard. Every battery tier needs it, every component line eats it. Get it flowing early or you will hit a wall the moment you try to scale.

A Sandleaf farm feeding directly into a Dense Originium Powder Factory is the cleanest setup — both fit on a single corridor of belts.

Step 3: Battery Factory (LC Wuling Batteries)

With powder flowing, build your first Battery Factory. The math is simple:

ComponentQuantity
Packagers1
Dense Originium Powder belts3
Xiranite belts1
OutputBasic LC Wuling Batteries

One fed packager powers every mining outpost and facility you will build through this phase. Surplus batteries sell to outposts for steady passive cash. Do not build a second packager until your network actually demands it — one is enough for a long time.

Step 4: Xiranite Component Factory

Combine Dense Originium Powder + Xiranite to produce Basic Xiranite Components. Let this run for a day or two, bank roughly 10,000 components, then pause it.

That buffer covers every early-to-mid Wuling demand. Free those forges and belts for higher-value work as soon as the stockpile hits target.

Pro Tip: Don’t run component factories continuously in Phase 1. Stockpile, pause, redirect. The forges are too valuable to dedicate to materials you only consume occasionally.


Phase 2 — Qingbo Stockade (Optional)

You have a real decision point here. Push into Qingbo Stockade now, or skip ahead to Marker Stone and circle back with better tools.

The honest take: Marker Stone makes everything in this phase significantly easier. If you can stand the wait, skip Qingbo’s factory work and come back to it after Marker Stone unlocks underground fluid routing and Expanded Crucibles.

If you are pushing through Qingbo now, here is the order.

Cuprium Refinery

Refines cuprium ore into cuprium metal. This is your first encounter with fluid mechanics in Wuling — the process emits sewage as a byproduct.

Critical detail: sewage is not waste. Later production lines require it as input. Anything you cannot use immediately should be routed to a water treatment plant to prevent pipe backups that stall the entire refinery.

Medicine Factory

A temporary line. Converts cuprium to medicine for personal use only. Build a small emergency stockpile and stop — there is a far better cuprium sink coming at Marker Stone via outpost trades. Do not overinvest.

Xircon Maker

The spaghetti monster of Phase 2. Combines Xiranite + Ferrium into Xircon, but the chain demands:

  • Sewage supply (from your Cuprium Refinery)
  • Water supply
  • Inert byproduct handling
  • Intermediate fluid transfers

Expect to wire together five standard crucibles to hit a steady output rate. Many players skip this entirely and wait for Marker Stone, where the same chain runs on two Expanded Crucibles with underground piping. Both approaches work — the standard-crucible build just costs you significantly more space and patience.

Cuprium Component Factory

Same playbook as Xiranite Components: run until ~10k Cuprium Components are banked, then switch off. No continuous supply needed for a long time.


Phase 3 — Marker Stone and Advanced Production

Once Marker Stone unlocks, the entire Wuling factory tightens up. If you skipped Phase 2, build the cuprium and xircon lines now — they are dramatically cleaner here.

The Xircon Maker Upgrade

Build LocationCrucibles NeededFluid Routing
Qingbo Stockade5 standard cruciblesSurface piping
Marker Stone2 Expanded CruciblesUnderground piping

Same output target, fraction of the space and complexity. This is why waiting pays off.

Heavy Xiranite Production

Combine Xiranite + purified xircon byproduct to produce Heavy Xiranite. This is one of the best cash items in early-to-mid Wuling:

  • Sells directly to outposts for excellent rates
  • Required for limited-time event submissions
  • Feeds hetonite component production

The purified byproduct comes from reprocessing what your xircon makers emit, so you are turning waste into a high-margin export.

Hetonite Production at Marker Stone

Marker Stone outpost gives you easy acid access, which unlocks hetonite crafting. The recipe consumes most of your refined cuprium plus a small ferrium dose.

Like Heavy Xiranite, hetonite has three exit doors:

  1. Direct sale to outposts (great cash)
  2. Event material submissions
  3. Upstream input for hetonite components

Hetonite Component Maker

The top of the early-game tech ladder: Heavy Xiranite + Hetonite -> Hetonite Components. These feed every higher-tier production line you will unlock after the early game, and they are nearly impossible to over-stockpile.


Moving Forward

With this backbone running, the next bottleneck shifts from materials to forges. AIC points become your primary grind target — every new forge slots into one of the patterns you have already built:

  • Drop another Xiranite Farm block
  • Scale Dense Originium Powder
  • Add a second battery packager only when your outpost network actually consumes it
  • Tile xircon and heavy xiranite lines as needed

The map of progression is clean:

RegionAdds
Wuling (start)Xiranite, Dense Originium Powder, LC Wuling Batteries
Qingbo StockadeCuprium ore, Xircon (5-crucible build)
Marker StoneHeavy Xiranite, Hetonite, Hetonite Components, Xircon (2-crucible build)

By the time the story asks for higher-tier batteries, every intermediate you need is already automated. Higher tiers become a blueprint expansion, not a from-scratch rebuild.


Common Pitfalls

  • Skipping the Phase 0 battery stockpile — your first Xiranite Farm sits idle while you scramble for power
  • Running component factories continuously — 10k stockpile is plenty; free the forges
  • Pushing xircon at Qingbo when Marker Stone is close — five-crucible spaghetti versus two Expanded Crucibles is not a real choice
  • Treating sewage as waste — downstream recipes need it; route surplus to water treatment, not into the void
  • Building two battery packagers too early — one fed packager covers more than first-time players expect
