What Is Wuling?
Wuling is the second major region in Arknights: Endfield, unlocking at Authority Level 43 through the "Arrival at Wuling" main story quest. It introduces new mechanics, materials, and an entirely separate economy from Valley IV. If Valley IV is your early-to-mid game foundation, Wuling is where the endgame lives.
The region centers on Jingyu Valley, a mountainous area with its own resources, dungeons, and outpost. Everything in Wuling operates on parallel systems to Valley IV -- separate Stock Bills, unique crops, region-specific factory materials -- but nothing transfers directly between the two economies.
Valley IV vs Wuling Comparison
| Feature | Valley IV | Wuling |
|---|---|---|
| Unlock | Game start | Authority Level 43 |
| Stock Bills | Valley Stock Bills | Wuling Stock Bills (separate) |
| Signature Material | Ferrium, Amethyst | Xiranite |
| Factory Power | Manual wiring (Relay Towers + Pylons) | Auto-connecting Xiranite Pylons/Relays |
| Depot Bus | Fixed positions | Free-placement |
| Unique Crops | Buckflower, Sandleaf, Tartpepper | Yazhen, Jincao |
| Outpost | Refugee Camp, Infra-Station, Planned Construction Area | Sky King Flats |
| Gear Tier | Tier 0-2 | Tier 3 (endgame) |
Arrival Checklist
When you first unlock Wuling at Authority Level 43, follow this priority order:
- 1. Unlock all Jingyu Valley teleport points -- Wuling is large and has no fast travel until you activate them
- 2. Locate the Wuling Stock Redistribution terminal -- in the Jingyu Valley settlement area (see the Stock Redistribution Guide)
- 3. Transfer Valley IV batteries to a Wuling Thermal Bank for bootstrap power
- 4. Build your first Forge of the Sky to begin Xiranite production
- 5. Start gathering Yazhen and Jincao in the wild for endgame consumables
- 6. Set up Sky King Flats outpost to start earning Wuling Stock Bills
- 7. Explore for collectibles and resources -- use the interactive map to track progress
Pro Tip: Teleport Points First
Before doing anything else in Wuling, run through Jingyu Valley and activate every teleport point. The region is significantly larger than Valley IV, and backtracking without fast travel wastes enormous amounts of time. This takes 15-20 minutes and saves hours over the following weeks.
Wuling Economy vs Valley Economy
Wuling runs on a completely separate economy from Valley IV. The two Stock Bill currencies are non-convertible -- you cannot trade Valley Stock Bills for Wuling Stock Bills or vice versa. You need to build Wuling income from scratch.
Wuling Stock Bill Spending Priority
| Priority | Where to Spend | Why |
|---|---|---|
| 1 | Weekly Stock Redistribution | Best material rates in the game |
| 2 | Wuling terminal upgrades | Expand daily Elastic Goods limits |
| 3 | Wuling weapon store | Region-specific endgame weapons |
| 4 | Gear Assembly materials | Wuling Stock Bills used as crafting input |
Two Economies Running Simultaneously
You need to maintain both Valley and Wuling economies in parallel. Valley Stock Bills still matter for Valley-specific purchases and terminal upgrades. Don't neglect Valley outpost trading when you start Wuling -- keep both factory pipelines running. For trading mechanics, see the Stock Redistribution Guide.
Jingyu Valley Exploration
Jingyu Valley is the first area you access in Wuling. It is larger than any single Valley IV sub-region, with unique resources, enemies, and landmarks.
Key Things to Find
| Target | Priority | Notes |
|---|---|---|
| Teleport points | Critical | Activate all for fast travel |
| Yazhen & Jincao nodes | High | Begin wild collection on Day 1 |
| Mining spots | High | New ore types for Wuling recipes |
| Stock Redistribution terminal | High | Located in the main settlement area |
| Sky King Flats outpost | High | Unlocks via "Where Danger Sleeps" quest |
| Boss encounter locations | Medium | Scout locations before you're ready to fight |
Use the interactive map with 5600+ markers to find specific resources, collectibles, and landmarks across all Wuling sub-regions.
Wuling Factory Bootstrap
Your first challenge in Wuling is getting an AIC factory running with no local power infrastructure. Everything must be bootstrapped from Valley IV resources.
Bootstrap Strategy
- 1. Transfer Valley IV batteries (LC or SC Valley Batteries) to a Wuling Thermal Bank via your Depot
- 2. Run the Thermal Bank to provide initial power
- 3. Build a Forge of the Sky -- the Wuling-exclusive facility that produces Xiranite
- 4. Craft LC Wuling Batteries from Xiranite materials
- 5. Transition to local power as LC Wuling Battery production stabilizes
Key Differences from Valley IV
Auto-Connecting Pylons
Xiranite Pylons and Relays auto-connect to the PAC -- no manual wiring needed. Place them and they link automatically.
Free-Placement Depot Bus
Unlike Valley IV's fixed bus positions, Wuling lets you place the Depot Bus wherever you want. This makes layouts significantly more flexible.
2-Forge Limit
You can only build 2 Forges of the Sky total across all your Wuling AICs. Plan recipe allocation carefully before committing.
Pro Tip: Battery Transfer Trick
Before you arrive in Wuling, stockpile 20-30 SC Valley Batteries in your Depot. The moment you unlock Wuling, transfer them to a Thermal Bank at your first Wuling AIC. This gives you enough runway to get Xiranite production started without any downtime.
For the full factory mechanics breakdown including power chains, Thermal Bank fuel efficiency, and production chain details, see the AIC Factory Guide.
Wuling Crops & Consumables
Two crop families are exclusive to the Wuling region and unavailable anywhere in Valley IV. Both produce endgame-quality consumables.
| Crop | Location | Products | Use |
|---|---|---|---|
| Yazhen | Jingyu Valley, Wuling | Yazhen Spray (S/L), Yazhen Syringe (C/A) | Endgame heal-over-time items |
| Jincao | Wuling (exclusive) | Jincao Drink, Tea, Tisane, Infusion | Tiered instant healing + buffs |
Why These Matter
Yazhen Spray S/L
Among the best heal-over-time items in the game. Scales with Max HP percentage, making them effective at every gear level.
Jincao Infusion
Provides the highest single-target instant healing in the game (22% Max HP + 1,954 flat). Essential for endgame boss attempts.
Start gathering wild specimens immediately upon arriving -- even before your planting loops are set up. Early specimens feed your Seed-Picking Units later.
For crop loop setup, see the Planting Guide. For consumable tier lists and loadouts, see the Consumable Strategy Guide.
Xiranite Priority Crafting
With only 2 Forges of the Sky available total, what you craft and when matters significantly. Poor allocation stalls your progression.
Recommended Forge Allocation
| Phase | Forge 1 | Forge 2 | Goal |
|---|---|---|---|
| Arrival | Xiranite (raw) | -- (not yet built) | Stockpile raw material |
| Building Up | LC Wuling Batteries | Xiranite Components | Power self-sufficiency + components |
| Endgame | Based on bottleneck | Based on bottleneck | Optimize for current needs |
Key Crafting Chain
Xiranite (raw) → Xiranite Components → LC Wuling Batteries
LC Wuling Batteries power your Wuling factory. Until battery production is self-sustaining, you depend on Valley IV battery transfers. Achieving power independence is the first milestone.
For detailed production chain layouts and Protocol Stash logistics for splitting recipes across AICs, see the AIC Factory Guide.
Sky King Flats Outpost
Sky King Flats is Wuling's only outpost, located in Jingyu Valley. It is your sole source of Wuling Stock Bills from outpost trading.
Unlock Requirements
- * Complete the "Where Danger Sleeps" main mission
- * Complete the subsequent exploration mission
- * Authority Level 43+
Trading Strategy
Wuling Stock Bills Only
All trades at Sky King Flats earn Wuling Stock Bills. These are separate from your Valley income and cannot be mixed.
Operator Liaison Bonuses
The same three bonus types apply: SAR Response (Faction, +1 Prosperity), Turn Scrap to Treasure (Hobbies, +1 Stock Bill), Survival Knowledge (Expertise, +1 Stock Bill). Assign matching operators for a 20% trigger chance on every trade.
Start Immediately
Begin trading as soon as you unlock the outpost. Wuling Prosperity leveling starts from zero, and every missed day compounds into delayed factory expansion and lower trade returns.
For full outpost mechanics, Prosperity leveling, and Operator Liaison attribute matching, see the Outpost Guide.
Wuling Dungeons & Combat
Wuling dungeons represent endgame difficulty. They drop the materials needed for Tier 3 gear sets -- the best equipment in the game. Come prepared.
Recommended Preparation
| Requirement | Minimum | Recommended |
|---|---|---|
| Authority Level | 43 (unlock) | 45+ |
| Gear Tier | Tier 2 minimum | Tier 2 with good substats |
| Consumables | Yazhen Spray + healing items | Full loadout with buff food |
| Team Comp | Element-matched teams | Optimized rotations |
Gear Path
Wuling Dungeons → Tier 3 Gear Template Crates → Endgame gear sets (MI Security, Type 50 Yinglung, Tide Surge, Bonekrusha, Swordmancer, LYNX, and more)
For all Tier 3 gear sets and their 3-piece bonuses, see the Gear Sets Guide. For combat mechanics and skill rotation optimization, see the Combat Mastery Guide.
Level 43-60 Progression Roadmap
After arriving in Wuling, your priorities shift from Valley IV expansion to endgame preparation. Here is the recommended order:
| Priority | Action | Why |
|---|---|---|
| 1 | Set up Wuling factory | Everything depends on Xiranite production |
| 2 | Unlock Sky King Flats outpost | Start Wuling Stock Bill income stream |
| 3 | Begin Yazhen/Jincao gathering | Endgame consumables take time to stockpile |
| 4 | Upgrade Wuling terminal | Better Elastic Goods access |
| 5 | Farm Wuling dungeons | Tier 3 gear progression |
| 6 | Push Wuling RDL | Resource purity and facility limits |
| 7 | Optimize both Forges | Maximize Xiranite throughput |
Pro Tip: Factory Before Dungeons
When you arrive in Wuling, resist the urge to immediately farm dungeons. Your first priority is getting the factory running -- Xiranite production, LC Wuling Batteries, and the Depot Bus. A self-sustaining Wuling factory generates passive income and materials 24/7, making everything else faster. Dungeons can wait a day; factory compound interest cannot.
Regional Development
Wuling has its own Regional Development Level (RDL), tracked separately from Valley IV. Raise it through:
- * Outpost Prosperity -- largest contributor via Sky King Flats trading
- * Factory upgrades -- expanding and upgrading Wuling AIC facilities
- * Main story missions -- Wuling story progression
- * Mining spot construction -- building rigs at Wuling ore veins
Higher Wuling RDL improves resource purity at mining spots, spawns rarer growths, and unlocks additional facility slots. For how Prosperity and RDL work, see the Outpost Guide. For what each Authority Level unlocks, see the Authority Levels Guide.
Common Mistakes & How to Avoid Them
1. Trying to Convert Valley Stock Bills to Wuling
Valley and Wuling Stock Bills are completely separate currencies. You cannot exchange one for the other. Budget for earning Wuling Stock Bills from scratch via Sky King Flats outpost trading.
2. Not Bootstrapping Power with Valley IV Batteries
Arriving in Wuling with no pre-stockpiled batteries means your first Forge of the Sky sits idle while you scramble for power. Transfer 20-30 SC Valley Batteries before you arrive to avoid factory downtime.
3. Wasting Both Forge of the Sky Slots
You only get 2 Forges total across all Wuling AICs. Allocating both to the same recipe halves your production diversity. Plan recipe distribution before building the second Forge.
4. Ignoring Yazhen & Jincao Gathering Early
These Wuling-exclusive crops produce endgame consumables you will need for dungeons and bosses. Start wild gathering on Day 1 -- even before planting loops are set up. Early specimens feed your Seed-Picking Units later.
5. Skipping Teleport Point Unlocks
Wuling is vast. Without teleport points, every trip is a long manual run. Unlock all Jingyu Valley teleport points before doing anything else -- 15-20 minutes invested saves hours over the following weeks.
6. Over-Investing in Valley IV Factory
At Level 43+, your endgame progression depends on Wuling materials (Xiranite, Tier 3 gear). Put Valley IV factories on autopilot while you focus expansion energy on Wuling. Valley production should be self-sustaining by now.
7. Not Setting Up Sky King Flats Immediately
Every day without the outpost is a day without Wuling Stock Bill income. The compound loss adds up significantly over weeks. Make outpost unlock a top-3 priority upon arriving in Wuling.
8. Bringing Underpowered Teams to Wuling Dungeons
Wuling enemies are Authority Level 43+ difficulty. If your gear is still Tier 1 or early Tier 2, you will struggle and waste Sanity on failed runs. Farm Valley IV dungeons for solid Tier 2 gear first, then transition to Wuling content when you can clear reliably.

Frequently Asked Questions
How do you unlock the Wuling region in Arknights: Endfield?
Reach Authority Level 43, then complete the 'Arrival at Wuling' main story quest. This opens the Wuling region with Jingyu Valley as the first accessible sub-area. Wuling introduces Xiranite, new crops (Yazhen, Jincao), Tier 3 gear sets, and a separate Wuling Stock Bill currency.
How do you set up a factory in the Wuling region of Arknights: Endfield?
Bootstrap power by transferring Valley IV batteries to a Wuling Thermal Bank. Build a Forge of the Sky (max 2 total) to produce Xiranite, then craft LC Wuling Batteries for local power. Wuling AICs feature auto-connecting Xiranite Pylons and free-placement Depot Buses, making layouts more flexible than Valley IV.
What are Wuling Stock Bills and how are they different from Valley Stock Bills in Arknights: Endfield?
Wuling Stock Bills are a separate currency earned from Sky King Flats outpost trades and Wuling region activities. They cannot be converted to or from Valley Stock Bills. Spend them on Wuling Stock Redistribution terminal upgrades, Wuling weapon stores, and endgame materials only available in the Wuling region.
What should you do first when you arrive in Wuling in Arknights: Endfield?
Unlock all Jingyu Valley teleport points for fast travel, transfer Valley IV batteries to bootstrap your first Wuling AIC, build a Forge of the Sky for Xiranite production, set up the Sky King Flats outpost for Wuling Stock Bills, and start gathering Yazhen and Jincao crops in the wild.
