(clears out Stock Bill savings everyday with leftovers) * \* **Additional Parts and Bottles** \- for Combat Facilities and Ziplines, or to just use up idle ore. * \* **Explosives, Buck C and Citrome C** \- whether it's 12/min or 24/min production, you'll hit the 80k cap anyway, so I'd rather produce varied items and extra parts. ### Why This Factory? This factory nearly Maxes out Yield of all Ores and still has Extra Space in Core AIC Area the size of a whole Outpost. What more do you need in the endgame? :) And if you do need something, you'll have to turn off some of the above units to free up ore. To make that management easier, there's extra space in the Core AIC area - along with the added convenience of almost never needing to shuffle between outposts to do it. I've tried to "Future-proof" this as much as possible with extra space and parts, while keeping it practical. It works for me - and hopefully for some of you too. Some players like to use the extra space for Ziplines or additional items that might be useful later. ### Production Rates Buck Capsule A18/min HC Valley Battery18/min Industrial Explosives6/min Buck Capsule / Canned Citrome C12/min Sandleaf Powder43200/day (free resource for deliveries) ### Extra Parts Production * \* 1x Amethyst & Cryston Parts/Bottles * \* 1x Ferrium & Steel Parts/Bottles (refer to guide) ### Active Ore Usage/Yield Originium Ore540/560 Amethyst Ore210/240 Ferrium Ore1080/1080 ### Blueprint Codes (Asia Server) Outpost 1&2 `EFO013o7241uEiau20i79` `EFO013o7241uEiau80i7u` Outpost 3 `EFO013o7241uEia990179` `EFO01I3A5O0o479a75308` Core AIC `EFO01u8U45aI2e0e5AIOU` `EFO01u8U45aI2e0e9A9OU` `EFO019aEuIi635e6U5OI2` `EFO01iUIa0Ee132aa72U4` `EFO012O9Aio4Ua8aoeIOo` ### Blueprint Codes (NA/EU Server) Outpost 1&2 `EFO01893iaI8UI12oUi73` `EFO011ea2A91O9U2634O7` Outpost 3 `EFO01eE7I5Ae3A48oAi8` `EFO010U95e1021i1OE179` Core AIC `EFO012I403O21O8AeIOo` `EFO0172UoOi7ui554O0Ai` `EFO01A5i327Ao7E69ieO` `EFO01U4A8EeUIeOEi7Oa8` `EFO01iOeu4Ui8U2ee72U4` \* Credits to u/Prior\_Theme\_8587 for replicating them to NA/EU ### Known Bugs & Fixes Stuck in Valley Pass, Refugee Camp after teleporting to the Sub PAC Teleport to another TP point, walk back to the factory and just rotate the Sub-PAC 180 degrees and replace the items in the item ports. Now you can teleport back to the Factory without issues. Facility Limit reached in Valley Pass For this, you'll need to try a couple of things. Remove the item control ports of Outpost 3 A blueprint and re-connect the belts, then place Outpost 3B. If this doesn't work, then you'll need to remove the Combat facilities in the Outpost outside the factory space temporarily and then try to place the blueprint (this is a very odd bug as the facility limit within the factory space and overworld facility limit should be separate) Top left Electric Pylon not placing outside Power Plateau, Reconstruction HQ Factory Just need Lvl 2 Reconstruction HQ outpost for the Pylon to be placed. **Explanation:** Due to the change in environment of the Outposts for every level upgrade, You may not be able to place the Electric pylon as instructed in the guide. For this you just need lvl 2 of the outpost to place the pylon, as that seems to clear up the space. Till then you will have 17.25/min Buck A production instead of 18/min till you get to Reconstruction HQ Lvl 2\. You will still be able to empty stock bill savings with 17.25/min so don't worry about it! First time making guides & posting on reddit, feel free to ask anything and/or leave some feedback here or on Discord in the Official Endfield Discord Thread for this Factory. ## Wuling City (Main AIC - Riverine Megabase) This Riverine Megabase requires fluid pumps and a stable Sandleaf loop for battery and Xiranite production. | Segment | Key Function | NA/EU Server Code | Asia Server Code | | ------------ | ---------------------------- | -------------------- | --------------------- | | Top Left | Sandleaf & powder processing | EFO011eaiaA147U734O7 | EFO017i89o19ia535O0Ai | | Top Right | Wuling Battery assembly | EFO01eE7O75eo24ioAi8 | EFO01194o23o9uUa634O7 | | Bottom Right | Xiranite Forge array | EFO01O3E8EoOauIi9oe4 | EFO01a6584u86IAeUoe5e | | Left Middle | Yazhen Syringe assembly | EFO0172UEUO7845AO0Ai | EFO01602IE8I03799O83e | | Left Bottom | Gold Gear components | EFO01iOe5e4iIE2A72U4 | EFO0101O35I31oiaUE179 | ### Pro Tip: Xiranite Pylons Wuling introduces **Xiranite Pylons** and **Xiranite Relays** that auto-connect to the PAC and each other within range, eliminating manual wiring. This is a significant convenience upgrade over Valley IV. ## Wuling Outpost - All-in-One Production Hub An optimized all-in-one Wuling outpost combining syringe production, battery manufacturing, and Xiranite component fabrication in a single fully-upgraded outpost. ![Wuling Outpost All-in-One Factory Blueprint - Syringe and Battery Production Setup](https://endfieldhub.org/images/guides/endgame-blueprints/wuling-outpost-allinone.webp) Wuling Outpost All-in-One Setup Guide ### Production Output Yazhen Syringes 6/min Single production chain LC Wuling Batteries 11.33/min Dual production chains Xiranite Components 3,000+/week \~1/9 Xiranite input Note: Battery production is limited to 11.33/min instead of 12/min due to resource competition with gear components for Xiranite and Originium. ### Requirements * \* **Fully upgraded outpost** \- This is a large build requiring maximum outpost level (not the HUB, but a standard outpost). The outpost upgrade cost is relatively affordable. * \* **All Ferrium resources** \- Requires 120 Ferrium total (90 from local map deposits + 25 from automated Valley IV transfer + 5 buffer). Being short by 5 Ferrium will have minimal impact. * \* **Most Originium deposits** \- Secure the majority of available Originium in the Wuling region for optimal production. ### NA/EU Server Codes Part 1 (East) `EFO01Eu24IA6E6oA3oIa` Part 2 (North-West) `EFO0172UA46u7u56O2Ai` Part 3 (South-West) `EFO01Eu24IA6E6oE3uIa` ### Asia Server Codes Converted and tested for Asia server by AramisFR Part 1 (East) `EFO01eAo0Oa2aO48oAi8` Part 2 (North-West) `EFO01E50U37I73o239Ia` Part 3 (South-West) `EFO01Ue3629592O67Oa8` \* Asia codes converted by AramisFR with fixes for overlapping pylon (SW) and missing pylon (E). ### Setup Instructions Step 1: Water Pump Installation Place **3 water pumps** on the eastern side of the build area. Each pump services 2 buildings requiring water (6 buildings total). Run the water pipes outside the construction area - this is permitted and won't interfere with the blueprint placement. Step 2: Farm Initialization Configure the farms according to their grouping pattern: * \* **Sandleaf farms** \- Group of 3 (2 farms + 1 seed dispenser, no water pipe) * \* **Wuling plants (Yazhen)** \- Group of 2 (1 farm + 1 seed dispenser with water pipe) Step 3: Power Connection Connect all buildings to the power grid using Xiranite Pylons. The pylons will auto-connect to the PAC and each other within range. ### Credits & Attribution Original blueprint design and optimization by community contributors. Special thanks to: * \* Original creator for the extensive hours spent designing and testing this optimized layout * \* **AramisFR** for converting and testing the blueprints for Asia server, including critical fixes for pylon placement ## Sky King Flat (Construction Site) A specialized outpost for wireless power transmission and high-speed medical supply chains. ### Wuling Battery Setup NA/EU Server `EFO01iOe7EA9iI2eI72U4` ### Battery Setup Asia Server `EFO018Ieo6a6o4127UI73` ### Xiranite Forging (2x) NA/EU Server `EFO01eE7U2i6eo4auoAi8` ### Liquid Xiranite (18/min) Asia Server `EFO01Ue37A20e8Oi7Oa8` ### Modular Syringe Line NA/EU Server `EFO01Eu24IA6E6oA3oIa` ### Modular Syringe Line Asia Server `EFO013o7810185auE0579` ## Technical Tips for Blueprint Success ### Server Compatibility **Blueprint codes are locked to their specific regions.** NA/EU codes will not work on Asia servers and vice versa. Always verify you're using the correct code for your server region before importing. ### Requirements Checklist Before importing any blueprint, ensure you have: * \* Unlocked the required perks (like Forge Expansion) * \* Sufficient machines in your inventory * \* Required Regional Development Level * \* All mineral beds unlocked for that region ### Powering Up Most endgame bases require an initial stockpile of **10-20 batteries** to kickstart the Thermal Banks before the automated loop stabilizes. Keep backup Thermal Banks on raw Originium Ore to prevent total blackouts during transition. ### Resource Management Wuling is naturally low on Ferrium. Use the **Metastorage system** to transfer about **1,500 Ferrium per week** from Valley IV to keep Wuling syringe production running at 100% capacity. Plan your weekly logistics route accordingly. ## Blueprint Curation For an expanded collection of community-curated blueprints beyond the endgame series, check out our[Blueprint Curation](https://endfieldhub.org/guides/blueprint-curation) page.

No. Blueprint codes are locked to their specific regions. NA/EU codes will not work on Asia servers and vice versa. Always use the code that matches your server region. ### How many Forges of the Sky can I build in Wuling? You can build a maximum of 2 Forges of the Sky total across all your Wuling AICs. Plan your recipes carefully - if one Forge is dedicated to LC Wuling Batteries, the other is your only slot for Xiranite Components. ### Why is Ferrium low in Wuling and how do I fix it? Wuling is naturally low on Ferrium deposits. Use the Metastorage system to transfer about 1,500 Ferrium per week from Valley IV to keep Wuling syringe production running at 100% capacity. ### Do I need batteries before importing blueprints? Yes. Most endgame bases require an initial stockpile of about 10-20 batteries to kickstart the Thermal Banks before the automated loop stabilizes. Prepare this stockpile in advance. ### What perks do I need unlocked before using these blueprints? Ensure you have unlocked perks like Forge Expansion and have enough machines in your inventory. Check each blueprint's requirements before importing to avoid placement failures. Keep Endfield Hub free Every calculator, planner and guide here is free, and it stays that way.
