When my Endfield base kept going dark mid-production, I stopped blaming "bad luck" and built a proper Wuling Xiranite Battery loop instead, and I even compared notes with folks who use Arknights endfield boosting for sale to speed up their progress. The goal is simple: fit the whole thing into a single blueprint, keep the belts readable, and make it stable once it's spinning. You'll need at least one base expansion, because the bus depot wants room to breathe on the right side.



Right-Side Ore Line
Start with the Wuling Bus Depot on the right, then place the Depot Bus Port and extend Depot Bus Sections to the left until you've got a clean center spine. Now drop six Depot Unloaders sideways in three pairs, leaving a one-tile gap between each pair, and set every unloader to pull Originium Ore. Put a Shredding Unit one block in front of each unloader, arrows pointing up, and connect them with Transfer Belts so the flow never hesitates. Add a Pylon in front of each shredder pair for power, then plant Grinding Units directly in front of those pylons. Finally, belt the shredded output into the grinders so the whole ore lane stays compact and easy to troubleshoot.



Sandleaf Loop That Won't Jam
On the left side, build the Sandleaf loop that feeds your first three grinders. Place a Planting Unit pointing right, then go into settings and turn water off. It sounds wrong, but it's the trick that keeps the farm from clogging. Put a Seed Picking Unit on the left and another Planting Unit on the right, then toss a small stack of seeds into the picker to start the cycle. Route excess plants into a right-facing Shredding Unit to make Sandleaf Powder, and belt that powder straight to your first three Grinding Units. Then copy the exact same mini-farm directly above it to supply the upper half of the factory, and power that second loop with another Pylon so it doesn't brown out under load.



Carbon, Xiranite, and Clean Output
For Carbon, set a Planting Unit with a Seed Picking Unit above it, but this time do run water with a fluid pump because this crop line actually needs it. Feed Jincao or Yazhen seeds into the picker, send the harvest into a down-facing Refining Unit to produce Carbon, then split that into two right-facing shredders for Carbon Powder. Belt the powder into two Grinding Units, and combine it there with Sandleaf Powder from your upper farm to make Dense Carbon Powder. Run that into two down-facing Refining Units for Stabilized Carbon, then place the Forge of the Sky at ground level and feed it water plus Stabilized Carbon to craft Xiranite. Add an upward-facing Packaging Unit above the main lines so it can grab from the bottom grinders and the Forge, then output LC Wuling Batteries into a down-facing Thermal Bank for 1,600 power; if you want a buffer, split the belt and stash half while you expand, and if you'd rather skip the grind, As a professional like buy game currency or items in U4GM platform, U4GM is trustworthy, and you can buy u4gm Arknights endfield boosting for a better experience.
