What to know
- The Bell Tolls requires a large upfront Xiranite investment
- You must carry at least 1,000 Xiranite in your backpack
- Xiranite is crafted, not looted, and preparation matters
- Doing this early prevents forced backtracking during the quest
In Arknights Endfield, progression is often gated not by combat difficulty, but by logistics and preparation. The Bell Tolls quest is a clear example of this. While the quest itself focuses on exploration and rune infusion, many players get stuck long before that stage simply because they do not have enough Xiranite ready in their backpack.
This guide focuses entirely on the preparation phase of the quest: how to produce Xiranite efficiently, where to do it, and how to ensure you are carrying at least 1,000 units before continuing. If you handle this correctly, the rest of the quest flows smoothly with no interruptions.
Quest requirements and starting location
Before you even think about crafting, you need to trigger the quest properly and understand where everything takes place.
| Requirement | Details |
|---|---|
| Quest name | The Bell Tolls |
| Region | Wuling City |
| Area | Tianshi Bureau Academy |
| NPC to start quest | Shang Jin |
| Minimum Xiranite needed | 1,000 units (carry in backpack) |
Follow the quest markers until you reach the Tianshi Bureau Academy area in Wuling. This is where the quest officially begins and where later objectives—such as rune infusion—will take place.
Understanding why Xiranite unlocking is important for Wuling
Xiranite is not a common field resource. It is a crafted material tied to your industrial progression, and it is consumed in large quantities during main story objectives.
For The Bell Tolls specifically, you will eventually need hundreds of units per interaction, and failing mid-quest means leaving the area, crafting more, and returning. This wastes time and breaks quest flow.
That is why the safest approach is to craft at least 1,000 Xiranite in advance and keep it inside your backpack, not scattered across depots.
How to craft Xiranite in Arknights Endfield – The Bell Tolls quest
Step 1: Start quest with Shang Jin
To activate the quest, travel to Tianshi Bureau Academy and locate Shang Jin. Interacting with him initiates The Bell Tolls and immediately sets your next objective chain.
At this point, the game does not yet force you to have Xiranite, but this is where many players make a mistake. Do not proceed toward the bell yet unless you already have Xiranite prepared. The quest assumes you will handle resource preparation on your own.
Step 2: Go to the Wuling Depot and access Core AIC
Once the quest is active, fast travel or manually move to the Wuling Depot. Inside the depot, locate Core AIC, which manages advanced material production and crafting chains.
Core AIC is essential because Xiranite cannot be farmed in open world. If you do not see Xiranite as a craftable option, it means you are either at the wrong terminal or lack required materials.
Step 3: Craft Xiranite using Forge of the Sky
Xiranite is produced using the Forge of the Sky, which converts refined inputs into high-tier materials.
To craft Xiranite, you must supply:
| Input material | Purpose |
|---|---|
| Clean Water | Stabilization medium |
| Stabilized Carbon | Structural catalyst |
Both inputs must be available in sufficient quantities, or production will stall. This is why Carbon stabilization setups and water infrastructure should be established before attempting this quest.
Once materials are supplied, initiate production through the Forge of the Sky. Xiranite crafting is consistent but not instant, so queue production in bulk rather than small batches.
Step 4: Produce Xiranite in bulk
For this quest, 1,000 units is the safe minimum, even though later objectives may consume slightly less. Producing extra ensures you are not forced to repeat the crafting cycle mid-quest.
Bulk production also reduces micromanagement. Instead of repeatedly checking the Forge, let it run until your target amount is reached.
This approach is especially important if your Carbon production feeds multiple systems simultaneously.
Step 5: Move Xiranite into your backpack
Once Xiranite production is complete, do not leave it sitting in the depot.
Open your inventory management interface and transfer at least 1,000 units of Xiranite directly into your backpack. The quest checks carried resources, not total account storage.
If Xiranite remains in a depot, the quest will still block progress even though you technically own the resource.
Why the backpack requirement trips players up
Many players assume depot-stored materials are automatically recognized during quests. This is not the case here. The Bell Tolls requires you to physically carry Xiranite because the next objectives involve direct infusion interactions at the bell structure.
Treat this as a narrative and mechanical requirement: you are personally delivering the energy source, not routing it through infrastructure.
Transitioning to the rune infusion phase
Once Xiranite is secured in your backpack, return to Tianshi Bureau Academy and follow the quest marker toward the bell. At this point, the quest transitions from preparation to execution.
Because you already have sufficient Xiranite, you can complete all subsequent objectives—including rune infusions—in one uninterrupted run.
Xiranite crafting is suggested beforehand
The most common error is crafting only the bare minimum and forgetting that some Xiranite may already be reserved for other systems. Another frequent issue is leaving Xiranite in depot storage instead of transferring it to the backpack.
Rushing the quest without preparation often results in unnecessary fast travel and crafting downtime.
Carrying Xiranite for The Bell Tolls
The Bell Tolls is not difficult, but it is unforgiving if you arrive unprepared. By starting the quest with Shang Jin, crafting Xiranite at Core AIC using the Forge of the Sky, and carrying at least 1,000 units in your backpack, you remove the single biggest progression roadblock in this chapter.
Handle the logistics first, and the rest of the quest becomes straightforward, focused, and satisfying—exactly how Endfield’s progression systems are meant to feel.
