The conveyor belt sputtered, choked with raw materials, grinding your production line to a halt. Another shipment delayed. Another opportunity missed. In Arknights Endfield, expanding your factory’s storage isn’t just about hoarding resources—it’s about keeping the gears of progress turning.
Initially, the base game sets a limit on how many units you can store, regardless of the item type. You probably won’t notice this restriction right away. But if you want to fully automate your factory, you’ll have to raise that threshold. Here’s how to get more space in your depot.
Breaking Ground: Raising Base Storage in Arknights Endfield
Think about a growing city; at some point, it needs bigger warehouses and distribution centers. Similarly, in Arknights Endfield, increasing your storage capacity requires some serious in-game commitment. Continue the main quest until you gain access to the Originium Science Park. Finish the missions centered around Yavon, and be sure you have enough Valley Stock Bills.

You’ll then need to open the Depot Node. The Depot Node I quest is the first one you will gain access to. Completing it opens Depot Node II.
At a Depot Node, spend Valley Stock Bills to improve it. The depot capacity increases from 3000 to 6000 units each time you upgrade. These upgrades will increase the number of items you can keep in your base at any time.
What are Valley Stock Bills in Arknights Endfield?
Valley Stock Bills are your ticket to expansion. Consider them the local currency for improving your logistical capabilities. You’ll get them by completing specific missions and tasks within the game, so keep an eye on your objectives.

The Ripple Effect: Why Maximize Your Base Depot Storage?
Think of it like this: a small business owner might hesitate to invest in a larger space, but it opens the door to bigger contracts and greater efficiency. In Arknights Endfield, increasing base depot storage space costs a fair amount of Valley Stock Bills. But doing so lets you access the Pack Goods feature, an innovative delivery system.
How much are Valley Stock Bills worth?
The exact exchange rate can fluctuate based on in-game events and market conditions, but generally, a larger storage capacity translates to a higher valuation of your production efforts, drawing interest from other players and factions within Arknights Endfield.

By delivering these packed goods, you’ll be rewarded with—you guessed it—Valley Stock Bills. These Bills will become your main currency in Arknights Endfield, helpful for future upgrades and resource acquisition. A larger storage capacity provides a steady stream of income, making base depot storage upgrades a worthwhile long-term investment.
Are there other ways to get Valley Stock Bills?
