Once you get to Wuling, prioritize crafting Xiranite, LC Wuling Batteries, and Yazhen Syringe C.
Xiranite is the main ingredient for Xiranite Components, which is used to make Level 70 Gold Rarity Gear. LC Wuling Batteries will be the primary power source of your Wuling AICs, while the Yazhen Syringe C is the recommended Trade Good during the early levels of the Sky King Flats Construction Site Outpost.
Because of the complex recipes of the priority items, we highly recommend splitting the production into smaller parts. This makes it easier to manage, and allows you to build the production line over numerous AICs, which will be a huge help as your AIC will be on the smaller side until you upgrade it.
Splitting the production line requires extensive use of Protocol Stashes and the Wuling Depot Bus, so make sure that they are unlocked.

When crafting Xiranite and LC Wuling Batteries, you will need Stabilized Carbon and Dense Originium Powder, both of which require Sandleaf Powder. As such, make sure to have a constant source of Sandleaf in Wuling by creating a Seed-Planter Loop.
Best Blueprints and Factory Codes
| Xiranite Production Line |
|---|
![]() The first ingredient you need when making Xyranite are Stabilized Carbon. Refine Buckflower or Sandleaf into Carbon, then shred it into Carbon Powder. Afterward, grind it with Sandleaf Powder to make Dense Carbon Powder. Finally, refine it to get Stabilized Carbon. |
![]() Once you have Carbon Powder, you must then combine it with Clean Water using the Forge of the Sky. For 100% efficiency, make sure that you have two Stabilized Carbon lines feeding the Forge of the Sky. |
| LC Wuling Battery Production Line |
|---|
![]() The first ingredient you need when making the LC Wuling Battery is Dense Originium Powder. You can craft this by first shredding Originium into Originium Powder. Afterward, grind it with Sandleaf Powder to make Dense Originium Powder. |
![]() You will also need Xiranite when crafting LC Wuling Batteries. It is enough to follow the Xiranite production line explained above. |
![]() The last step to making LC Wuling Batteries is to package Xiranite and Dense Originium Powder together. For 100% efficiency, make sure you have three Dense Originium Powder inputs feeding the Packaging Unit. |
| Yazhen Syringe C Production Line |
|---|
![]() You will need both Ferrium Bottles and Ferrium Parts to craft the Yazhen Syringe C. Both Ferrium Bottles and Ferrium Parts start by refining Ferrium Ore. You can then pass it through a Fitting Unit to make Ferrium Parts, or through a Moulding Unit for Ferrium Bottles. For 100% efficiency, you will need to create two Ferrium Part lines, and one Ferrium Bottle line. |
![]() Using Yazhen and the Ferrium Bottles, you will then make Ferrium Bottle (Yazhen Solution). To do so, shred Yazhen to get Yazhen Powder and combine it with Clean Water in the Reactor Crucible to create Yazhen Solution. You must then pipe the Yazhen Solution into a Filling Unit alongside the Ferrium Bottle. Make sure you have unlocked the Fluid Filler Node in the Wuling AIC Plan to allow fluids in the Filling Unit. |
![]() Once you have Ferrium Bottles filled with Yazhen Solution, you can then combine them with Ferrium Parts using the Packaging Unit. Remember to feed two Ferrium Part Lines into the Packaging Unit for max efficiency. |

This is the compact version of the Yazhen Syringe C production line that shows the entire production process from start to finish. You can choose to build this if you have the space in your AIC.

The Yazhen is a Wuling Crop, and is one of the main ingredients when crafting a Yazhen Syringe C. Its biggest flaw, however, is that it only produces one seed when passed through a Seed-Picking Unit.
The blueprint above, which is an iteration of the Valley IV infinite seed-planter loop, will still infinitely create plants passively, but you will have to put not just one plant but atleast half a stack in the Seed-Planting Unit for a stable output. It is also less effective in terms of ourput, so you will need more Seed-Planter Loops compared to Valley IV crops to produce the same amount.
Also make sure that you have unlocked the Hydroponic node in the Wuling AIC Plan to allow you to grow Yazhen in the Planting Unit since it needs the input that allows you to connect pipes.

Before working on your AIC, try to play through the story until you unlock the first Wuling Outpost (Sky King Flats Construction Site). Doing so gives you access to the entire map, as well as reveals where the Mineral Beds are.
Completing all of the main missions up to this point will also reward you with a decent amount of Wuling Stock Bills, which you can use to unlock upgrades for your AIC.

As you are basically starting from scratch in Wuling, it is important that you take over all the available Mining Nodes. Once you unlock your first Outpost, go to the available Mineral Beds and place Mining Rigs on all available nodes. Take advantage of the Xiranite Pylon and Relay to easily power your Mining Rigs.
What is Mining Purity and How to Increase It

Unlike the Depot Buses in Valley IV that have fixed locations, the Wuling Depot Buses can be freely placed anywhere in your AIC, provided that the Depot Bus Sections are connected to a Depot Bus Port.
Take advantage of this by unlocking the Wuling Depot Bus node in the Wuling AIC Plan, as well as by upgrading your AICs to accommodate Depot Buses.

To improve your production capabilities, focus on increasing your Regional Development Level, as higher levels can increase Mineral Purity, as well as unlock additional mining nodes.

The seed planter loop is just as effective for Wuling crops as they are for Valley IV crops. While you only get 1 seed from the picking unit per plant, each seed grows into 2 plants in the planting unit. This means you can have the same effective loop as before with just one seed picking unit and one planting unit.
