Reaching Wuling in Arknights: Endfield often feels like you are starting over. You enter the region with zero Wuling Stock Bills, yet almost every important upgrade depends on them. Expanding your PAC, upgrading Stock and Depot, developing your Outpost, and crafting endgame gear all require a large and constant supply.
Just like in Valley IV, your ability to earn Stock Bills properly is a little bit gated behind story progression. Before trying to optimize anything, you should push the Wuling main story until you unlock the Outpost in Jingyu Valley.
Outposts remain the main source of Stock Bill income, but Wuling currently only has one Outpost, compared to three in Valley IV. Once unlocked, you can finally begin generating a nice income instead of relying on limited daily rewards.
Outpost Sales
Your first consistent source of Wuling Stock Bills will come from Outpost sales. As soon as your factory allows it, you should start producing Yazhen Syringe C. These syringes are the primary items traded with the Wuling Outpost and will provide a steady daily income.
This method is noticeably slower than Valley IV, mainly because of limited resources and the single Outpost. Still, it is an income that runs in the background and forms the base of your Stock Bill generation.
Environment Monitoring
One of the most important systems in Wuling is the Environment Monitoring Terminal, unlocked through the main story at the Monitoring Center. This system introduces photo-based missions, such as documenting some monsters or creatures in the open world, or taking a photo of some item or location. These missions refresh every two days and can give you a nice amount of Stock Bills.
Right after unlocking it, you can complete two missions that together reward around 80,000 Wuling Stock Bills. For players just starting in Wuling, this is by far the fastest way to get a good start. Once you completed this, you can use the Stock Bills to unlock your Stock Redistribution and your Depot!
Later on, you can also upgrade the terminal. It is expensive, but it increases both the number of available jobs and the amount of Stock Bills you earn.
Stock Redistribution
As soon as you can, you should unlock the Wuling Stock Redistribution.
This system unlocks the daily stock trading and quickly becomes one of the most reliable sources of Wuling Stock Bills. Once unlocked, it can be accessed directly from the Outpost menu. The process works the same way as in Valley IV: you buy items when prices are heavily discounted, then sell them at a friend’s base where prices are significantly higher.
With good timing, a single daily trade can turn a small investment into more than four times its value, making Stock Redistribution the best way to get Stock Bills fast.
Depot Deliveries
Another important system is the Depot Node in Wuling City. This is where you can package excess resources and deliver them for a large number of Stock Bills as rewards.
To get the best out of this, we recommend you transfer your deliveries to your friends and complete theirs in return. This way, both sides earn more Stock Bills than by handling deliveries solo.
The Best Wuling Stock Bill Approach
The best way to farm your Wuling Stock Bills is to unlock all income systems as early as possible, then build a simple daily routine around them.
The Outpost provides your base income, Environment Monitoring gives a good regular bonus, Stock Redistribution and Depot deliveries add a good amount each day as well.
This way, you have a nice income of Wuling Stock Bills each day, and you can upgrade the facilities and craft as much gear as you need.
