Progress the Story and Unlock the Sub-PAC

You can start farming Wuling Stock Bills after placing the Sub-PAC in Jingyu Valley and unlocking Outpost Trading. First, proceed with the main story until you clear Chapter 2 Process II, which allows you to place the Sub-PAC.
Ignore Stock Redistribution Terminal
Until you place the Sub-PAC and unlock Outpost Trading, there are very few ways to earn Wuling Stock Bills. We recommend ignoring the Stock Redistribution Terminal and Depot Node until the Core AIC is fully unlocked.
▼List of functions that can be unlocked with Stock Bills
Manufacture Xiranite
| Xiranite Blueprint and Code |
![]() |
EFO014E62A141I30eE71A EFO01eE7U1eO0A4a6oAi8 |
To prepare to earn Wuling Stock Bills, start by manufacturing Xiranite. This crucial material forms the foundation of Wuling's industry and is required for many products, such as batteries and Gear Components.
Manufacture and Trade Yazhen Syringe

| Yazhen Syringe [C] Blueprint and Code |

EFO01iUIA1oio524672U4 EFO011ea0u1io9U2634O7 |
Just like in Valley IV, you can earn Stock Bills via Outpost Trading in Wuling. We recommend starting with the Yazhen Syringe [C], as it is easy to produce and does not require Xiranite.
Trade Batteries Once AIC Advances
| LC Wuling Battery Blueprint and Code |

Once your AIC advances and you have a system for mass-producing Xiranite, add LC Wuling Batteries to your trade rotation. Since Yazhen Syringes and batteries require different materials, you can maximize your Stock Bill earnings by mass-producing both.
Unlock the Depot Node

The Depot Node can be unlocked after reaching Wuling City. It costs 12,500 Wuling Stock Bills, so wait to unlock it until Outpost Trading is active and you can earn bills efficiently.
Depot Node Location in Wuling City

The Depot Node is located at the edge of the Field Logistics Depot, southeast of Wuling City. The door is closed from the depot side, so you cannot enter directly. For the first time, you must take a detour from the east of Wuling City to reach the entrance.
Get Stock Bills by Trading Elastic Goods

In Wuling, you can also increase your Stock Bills by buying and selling Goods. However, since the Stock Redistribution Terminal level starts low, price fluctuations are minor, preventing massive immediate profits compared to Valley IV.
Stock Redistribution Terminal in Jingyu Valley

The Stock Redistribution Terminal for Wuling is located on the east side of Jingyu Valley. When you first arrive, you likely won't have enough Stock Bills to unlock it, so return later once you have accumulated the required Stock Bills.
Get Stock Bills from Environment Monitoring

You can also earn Wuling Stock Bills through the Environment Monitoring Terminal, unlocked during Chapter 2 Process II. Monitoring Jobs are completed simply by taking photos of specified objects, so you can easily earn bills without complex factory setups.
Monitoring Jobs Are Added Periodically

Monitoring Jobs are added periodically. If your slots are full of uncompleted requests, new ones will not appear, so be sure to complete them before the refresh.
Uses for Wuling Stock Bills
Unlock and Level Up Wuling Facilities
| Facilities That Can Be Unlocked With Stock Bills | |
Stock Redistribution Terminal | Unlocking it activates Wuling Stock Redistribution. Leveling it up increases the variety of products available. |
Depot Node | Unlocking it expands storage for each item in the Wuling depot and unlocks deliveries. Leveling it further increases storage limits and unlocks higher‑tier deliveries. |
Recycling Station | Unlocking it grants daily Aerospace Materials. Leveling it up improves the amount and rarity of building materials received. |
First, spend the Wuling Stock Bills you’ve gathered to unlock and upgrade facilities. The Stock Redistribution Terminal and Depot Node most directly affect earnings, so prioritize unlocking and leveling them as soon as possible.
Exchange for Items

At the Wuling Stock Redistribution Terminal, you can trade Stock Bills for exclusive Wuling items. The roster also includes Gear Blueprints, which unlock Gear when obtained, so exchange for them as needed.
Prioritize Wuling Artificing Catalyst

After you’ve upgraded facilities and acquired the basics, you’ll primarily earn Stock Bills to exchange for Wuling Artificing Catalyst. This catalyst is a crucial progression material for Gear Artificing and is required in large quantities.

Best Zipline Locations and Routes
Stock Bills Are Scarce at the Moment
In Wuling, mineable Ferrium is limited, and only two Forges of the Sky can be placed, which produce Xiranite, a vital component for the Wuling industry. Industrial production yields few Stock Bills, so supplement your earnings with the other methods listed above.
