The Wuling AIC factory is where Arknights: Endfield turns serious. This region funds your endgame, and your base is the engine. This Arknights Endfield Wuling AIC factory guide covers the full journey. We start with the goals and resources, move through the early, mid, and late layouts, then finish with advanced tricks and the questions players ask most.

Wuling is the second major region in the game. It unlocks around Authority Level 43 through the main story, and it brings an entirely separate economy. The Stock Bills, the crops, and the factory materials here do not carry over from Valley IV. Think of it as a fresh base with a steeper learning curve.
The new region also introduces several unique gameplay mechanics. Players can now pipe Clean Water into machines, unlock the Forge of the Sky—a facility exclusive to Wuling—and manage a dedicated AIC Plan with its own progression tree. Advancing through the AIC Plan also rewards Oroberyl, providing additional currency for gacha pulls while helping strengthen your roster.
Before placing a single belt, know what you are actually building toward. Everything in Wuling serves one of three goals.
Wuling adds a stack of new materials, and the names sound similar enough to confuse anyone. Here is a clean reference for the ones that matter.
| Resource | Where It Comes From | What It Powers |
|---|---|---|
| Xiranite | Forge of the Sky (2 Stabilized Carbon + Water) | Batteries, components, pylons, Xircon |
| Dense Originium Powder | Originium Ore refined with Sandleaf Powder | Both battery types |
| Xircon | Cuprium, Ferrium, and Liquid Xiranite chain | SC Wuling Battery |
| Cuprium Ore | Qingbo Stockade and Marker Stone | Cuprium Components, Syringe A, Xircon |
| Ferrium Ore | Limited Wuling nodes plus Valley IV transfer | Ferrium Parts, bottles, Syringe C |
| Sandleaf and Buckflower | Planting loops | Powders for the carbon and grinding lines |
| Yazhen | Wuling-only crop, planting loop | Yazhen Syringe and solution |
| Jincao | Wuling-only crop, planting loop | Jincao Drink |
Two quick notes save a lot of pain. Sandleaf feeds nearly every powder line, so treat it as your top priority crop. Yazhen and Jincao only grow in Wuling, so start gathering wild specimens the day you arrive. Those early plants seed your loops later.
Your Wuling base is not one build. It grows in stages, and the biggest limiter at every stage is the Forge of the Sky. This is the only building that makes Xiranite, and the game caps how many you can place.
That cap has risen with each update. It started at two Forges and expanded over later patches to four, six, and higher. Always check your version before copying a large layout, since older guides assume fewer Forges. The second hard limit is raw ore because Originium, Ferrium, and Cuprium are all scarce here.
The smart approach is to split production across the Core AIC and several Sub-PACs. Use Protocol Stashes and the Depot Bus to move materials between them. Do not try to cram one giant line into a single area.
The early game is all about survival. Your only real goal is power independence, so you can stop babysitting the base.
A common starter setup makes around 6 LC Wuling Batteries per minute. That is enough to power the base and still sell a surplus. Yazhen Syringe C is your best early trade good at the Sky King Flats outpost.
One early bottleneck catches everyone. Wuling mines only about 90 Ferrium Ore per minute, so your syringe and drink lines will run dry fast. Trim their Ferrium input to match, or plan for a Valley IV transfer later.
The mid game arrives with Cuprium. This is when your base shifts from surviving to earning. You will want Regional Development around Level 10 with the Marker Stone outpost unlocked to secure enough Cuprium Ore.
At this stage, you move to the SC Wuling Battery. It needs Xircon instead of just Xiranite, and each one gives a strong 3200 power to a Thermal Bank. A tuned mid-game base can push SC batteries at 12 per minute while also making Yazhen Syringe A and a trickle of gear components.
Yazhen Syringe A is worth prioritizing over Stock Bills. It also delivers the highest single-target instant heal in the game, which matters for hard boss attempts. Sell the surplus while keeping a stack for yourself.
The late game is the full mega base. You spread across the Core AIC and both outposts, all expanded to maximum area, with Regional Development pushed high enough to unlock the top Forge count and ore yields.
This is where Hetonite Components and Heavy Xiranite come online for the newest gear. You also lean hard on transfers from Valley IV to cover the Originium and Ferrium that Wuling cannot mine alone. With Valley IV maxed, Metastorage Transfer can move 750 Ferrium Bottles an hour, which removes the need for a local bottle line.
Once tuned, a late base mostly runs itself. You collect Stock Bills, craft gear, and only step in to top up transfers now and then.
These are the habits that separate a clean base from a jammed one.
It quietly feeds most powders. Keep it at full efficiency, and the majority of shortages simply vanish.
Refining Units produce Sewage. If it backs up, the machine clogs and stops. Either add a Water Treatment Unit or route the sewage straight into your Xircon chain. Reusing it is clean and saves belts.
That outpost returns acid as a byproduct. Drain it back into the pool. If you feed acid from both the pump and the byproduct, one side maxes out and freezes the line.
Batteries and gear components both pull from Xiranite and Xircon. Many players run a stable 6 and 6, then flip to 12 and 12 only when transferring resources. Add switches to the final steps for instant control.
The Cuprium and Hetonite gear does not out-stat Xiranite gear, but it costs far more Stock Bills per attempt. Craft it with the new components, then artifice using the cheaper Xiranite gear.
For income, stack your Stock Bill sources instead of relying on one. Outpost trading is only part of it. The Environmental Monitoring photo quests reward a large weekly sum, and daily Delivery Assist searches add plenty more. Both cost almost no effort.
Wuling opens around Authority Level 43 through the "Arrival at Wuling" main story quest. Reaching the first outpost, Sky King Flats Construction Site, reveals the map and the Core AIC.
The cap started at two and rose with updates to four, six, and higher in newer patches. Since it is version-dependent, check your current AIC Plan before planning a big Xiranite build.
Usually you overbuilt, or your Sandleaf loop is starving the battery line. Feed only a couple of batteries into your Thermal Banks, sell the rest, and import Valley IV batteries early to cover gaps.
Use LC Wuling Batteries early, since they only need Xiranite and Dense Originium Powder. Switch to SC Wuling Batteries once you have Cuprium and Ferrium flowing, as they give far more power and better trade value.
Sell batteries and syringes at your outposts, then stack passive income on top. The Environmental Monitoring photo quests pay a large weekly sum, and daily Delivery Assist searches add plenty more.
Stock Bills and finished regional goods do not cross over. However, Metastorage Transfer moves raw materials like Ferrium, Originium, and batteries from Valley IV to Wuling, which covers Wuling's ore shortages.
Almost always sewage. When Sewage has nowhere to go, the Refining Unit locks up and the line dies. Treat it or reroute it into Xircon production before it backs up.
The Wuling factory rewards balance over size. The Forge and ore caps mean a clean, well-split base beats a sprawling one every time. Lock in power first, then let outpost trading and photo quests print Stock Bills while you gear up your best teams.
Build it in stages, respect the two hard limits, and the Wuling base quietly carries your account through the endgame. That is the whole reason this region exists. It turns your factory time into gold gear, patch after patch.
