Arknights Endfield Yinglung Pass Guide: Map Unlock, Quests and Farming Routes
Yinglung Pass is the Version 1.4 gateway to North Wuling. Here's how to unlock it, clear the quest, and farm Aurylenes, crates, and new gas materials fast.
If you are pushing through Arknights: Endfield Version 1.4 "Homecoming," the single biggest "where do I go next" question is almost always the same: how do I open Yinglung Pass and the North Wuling Exclusion Zone, and what is worth farming there? The two new northern Wuling maps are the largest main-story expansion the game has received since launch, and they gate some of the best endgame loot — Tier 5 gear crates, new gas-production materials, and the Cloudseeder Station AIC outpost. This guide covers the exact unlock path, the full quest walkthrough, every collectible you can farm, and the most efficient routes so you clear the maps without backtracking.
What Is Yinglung Pass? (Version 1.4 New Map Overview)
Yinglung Pass is the sealed gateway into the forbidden northern territory of Wuling, introduced in the Version 1.4 "Homecoming" update. It is the first new area you cross to advance the main mission, and it sits directly north of Wuling City on the road toward the Very Large Rift. Unlike the lush, built-up Wuling City or the misty bamboo of Jingyu Valley, Yinglung Pass is a compact, mountainous connector zone — small in footprint but deliberately dense with collectibles and story beats.
According to the version preview and the official map guide summarized on BlueStacks' Arknights: Endfield region guide, Yinglung Pass is where Si, the mysterious Feranmut Proxy, makes her first story appearance, guiding the Endministrator through the final enhancement process of the Xiranite Nexus. Arcane — captain of the Yinglung Special Task Force — narrates the area's backstory and explains why the pass was sealed years ago. In other words, this is not a filler map: it is the narrative hinge that opens the ruined homeland beyond.
Yinglung Pass vs North Wuling Exclusion Zone
The two Version 1.4 maps are a pair, but they play very differently:
Yinglung Pass is the gateway. It is the smaller of the two, built as a connector, and it is where you meet Si and set up the Xiranflow Cloudseeder Station AIC outpost.
North Wuling Exclusion Zone is the deeper, more rewarding area — the ruined Wuling homeland now overrun by Blight Miasma. It holds far more chests and is where Arcane formally joins the Endfield Crisis Team for the boss fight against Alleikhreos, Chiliarch.
Both follow the same collectible structure as the rest of Wuling, so players already caught up on the story can clear them quickly.
How to Unlock Yinglung Pass (Step-by-Step)
Prerequisites — Story Progress
Yinglung Pass is not gated by Authority Level the way the original Wuling entry was. Instead, it is gated by main-story progress. Per the region unlock table in the BlueStacks map guide, Yinglung Pass unlocks by progressing Chapter 2 to the "Bravely Breach the Hostile Winds" mission, which you reach after completing Chapter II Process VII ("Ruins in the Miasma – Process VII," also referred to as "Stubbornly Lingers the Setting Sun"). In short: finish the Wuling City storyline, then keep moving north.
If you are a newer player using the Homecoming early-unlock feature, remember that the permanent "Main Mission Early Unlock: Wuling" lets you reach Wuling after Chapter I Process II — but Yinglung Pass and the North Wuling Exclusion Zone still require you to play through the Chapter II arc to the Bravely Breach the Hostile Winds step. There is no shortcut around that quest.
The "Bravely Breach the Hostile Winds" Quest Walkthrough
The unlock is a scripted story mission rather than a free-explore gate. Based on the step-by-step walkthrough published by GamerHour, here is the exact sequence:
Step | Action |
|---|---|
1 | Open the Mission menu and accept "Bravely Breach the Hostile Winds" (available after Chapter II Process VII). |
2 | Read Zhuang Fangyi's Message — open Messages, select Zhuang Fangyi, read the conversation, pick the dialogue option. |
3 | Return to OMV Dijang and speak with Zhuang Fangyi at the marked location. |
4 | Rest in the Reception Room — interact with the highlighted chair to trigger the next cinematic. |
5 | Follow the story sequence into the white-dimensional area; walk toward the highlighted mysterious girl (this is Si's first appearance). |
6 | Reach the Core AIC Area in Wuling City, then follow the waypoint toward Yinglung Pass. |
7 | Travel to Yinglung Pass — follow the mountain road; Arcane explains the pass's sealed history. |
8 | Enter Pass-Side Canal, the underground waterway connecting the quarantine zone. |
9 | Cross the Underground Canal — board the raft when prompted; it auto-carries the party across. |
10 | Activate the Transport Device at the highlighted terminal. |
11 | North Wuling Exclusion Zone unlocks — a final cinematic opens the quarantine barrier; access is permanent. |
Tip: The reception-room "rest" step and the white-dimensional cutscene are easy to miss if you blast through dialogue. Let them play — they set up Si, who is the character most players are saving pulls for after Arcane and Liino.
Unlocking North Wuling Exclusion Zone
North Wuling opens automatically at the end of the same quest line (Step 11 above). You do not need a separate Authority Level threshold for it — the "Bravely Breach the Hostile Winds" mission chains both areas together. Once the barrier drops, both Yinglung Pass and the North Wuling Exclusion Zone are permanently accessible, so you can farm them in any order.
If you want extra pulls for Arcane or Liino while you work through the new maps, a quick Arknights: Endfield top-up at Topuplist keeps your roster ready, with every pack available on the official Topuplist storefront.
Yinglung Pass Collectibles — What You Can Farm
Both new maps follow Wuling's standard collectible layout. According to Game8's map data (summarized in the BlueStacks region guide), here is the verified total per area:
Collectible | Yinglung Pass | North Wuling Exclusion Zone |
|---|---|---|
Aurylenes | 16 | 28 |
Treasure Chests | 26 | 85 |
Protocol Dataloggers | 4 | 4 |
Gear Template Crates | 2 | 0 |
Rare Growth spots | 2 | 0 |
Rare Ore spots | 1 | 1 |
These numbers make the two maps meaningfully different in value. Yinglung Pass is small but gives you the two Gear Template Crates needed for Tier 5 gear blueprints (the AIC Fieldwork and Rift Trekker sets are obtained in Wuling). North Wuling is the chest mine — 85 chests versus 26 — and the better long-term farming target once you just want materials.
What each collectible is for:
Aurylenes — glowing orbs submitted at any TP Point for Operational EXP, Origeometry, Stamina, and other exploration rewards. They do not respawn.
Treasure Chests — standard loot: T-Creds, materials, occasionally blueprints.
Protocol Dataloggers — the yellow "balloon men" that grant AIC Index for factory research once you have access authorization (unlocked after Chapter I Process I). Per the Protocol Datalogger explainer on Techcratic, interacting with them funds your AIC Plan tech tree.
Gear Template Crates — the source of gear-set blueprints, including the new Tier 5 sets.
Rare Growth / Rare Ore spots — rare gathering nodes for high-tier crafting inputs.
Farming Routes — Efficient Material & Collectible Paths
The fastest way to clear both maps is to submit Aurylenes as you go (they bank progression rewards immediately) and clear chests and crates in a single loop rather than revisiting. Because both areas are compact, a methodical ring route beats scattered exploration.
Aurylene Route (Submit for EXP/Stamina/Origeometry)
With 16 Aurylenes in Yinglung Pass and 28 in North Wuling, the two maps add 44 orbs to the game's ~240 total Aurylene pool. The most efficient approach:
Activate every TP Point first. TP Points clear fog, restore team HP, and are where you submit Aurylenes — so unlocking them as you enter each zone gives you rest stops and submission points in one move.
Walk through orbs, do not zipline. Community testing confirms that riding a zipline through an Aurylene does NOT collect it — you must physically walk into the orb. This is the single most common reason players miss collectibles, so use your scanner for hidden orbs that distort light.
Submit in batches. Each submission tier scales rewards (Stamina, Origeometry, Operational EXP), so banking a region's orbs before moving on compounds the benefit.
Gear Template Crates & Protocol Dataloggers
The two Gear Template Crates in Yinglung Pass are your priority if you are chasing Tier 5 gear (AIC Fieldwork / Rift Trekker). Grab them during your first pass — they do not respawn, and the new Wuling sets are best-in-slot for Version 1.4. The four Protocol Dataloggers in each area feed your AIC Index; since the 1.4 AIC overhaul adds Gas production, every point of AIC Index helps you research the new gas tech lines faster.
If you are short on pulls for the 1.4 headliners while farming, the Arknights: Endfield top-up page at Topuplist stocks every pack, and the full catalog is on the official Topuplist site.
New 1.4 Materials — Inergen, Xiragen & the Cloudseeder Station
Version 1.4 introduces Gas as a new industrial material state alongside solids and liquids. The new gaseous resources — Inergen and Xiragen — plus Pyrrolite Components / Pyrrolite Gas — are collected and processed through the new Xiranflow Cloudseeder Station, an AIC outpost that becomes available in Yinglung Pass itself. This is a major reason to rush the pass: establishing the Cloudseeder Station early lets you produce Xiranite directly from Carbon and Clean Water in an Inergen environment, skipping three intermediate production steps.
Material / Facility | Type | Where It Comes From | Why It Matters |
|---|---|---|---|
Inergen | Gas resource | Gathering + Cloudseeder Station (Yinglung Pass) | Feeds new gas conversion lines |
Xiragen | Gas resource | Gathering + Cloudseeder Station | Enables Pyrrolite Component crafting |
Pyrrolite Component / Gas | Crafted | Cloudseeder Station recipes | Used in new Tier 5 gear |
Xiranflow Cloudseeder Station | AIC outpost | Unlocks in Yinglung Pass | New industrial output; streamlines Xiranite |
The practical payoff: set up the Cloudseeder Station the moment Yinglung Pass opens, even before you farm chests. Gas production runs in the background while you explore, so you return to a stocked factory.
New Enemies, Boss & Combat Tips
The new maps are not free walks. Two new threats debut here, and the boss has a mechanic you must respect.
Blightshades
Blightshades are phantoms of fallen Yinglung Special Task Force soldiers, born from emotions stored by the Aether. They appear across both maps and hit harder in groups. Treat them as priority targets in any pull — they punish clustered, distracted teams.
Alleikhreos, Chiliarch — Boss Mechanics
The Version 1.4 boss, Alleikhreos, Chiliarch, is an enormous stony foe who attacks with bow, sword, and lance. Crucially, he cannot be countered by conventional means — several of his attacks must be interrupted using specific battlefield mechanics (the same Fluid Supply Unit puzzles introduced in 1.4, used to clear small rifts in the wild). Before you push the main mission, tune your team and learn the interrupt windows; a team that only dps-races him will get wiped on his scripted attacks.
A solid pull plan helps here: if your roster is thin, banking for Arcane (who deals Corrosion and Arts Infliction that rewards grouped, debuffed enemies) is often the safer route into this fight. The Arknights: Endfield recharge option at Topuplist is the official place to top up, with all bundles listed on Topuplist.
Why Rush Yinglung Pass? (Story & Rewards)
Beyond loot, the pass is worth rushing for three reasons:
It concludes the Wuling arc. Ten years after the Very Large Rift destroyed the Wuling Science Station, the Xiranite Nexus finally lets the people reclaim their homeland. Yinglung Pass is the emotional gateway to that payoff, and Si's introduction sets up the most-saved-for character after this version.
It unlocks the Cloudseeder Station early. Gas production is the biggest base-building change in 1.4; the sooner it runs, the more you save on later grinding.
Free rewards stack. Version 1.4's Half-Year Celebration hands out 3,000 Oroberyl on login, 2,000 via mail, 5 Basic + 10 Limited HH Permits, and the free 6★ Sword "Farsight." Pushing the story fast means you hit pull-efficient state quicker.
Reason to Rush | What You Gain |
|---|---|
Story completion | Si intro, Wuling arc payoff, Alleikhreos fight |
Cloudseeder Station | Gas production, faster Xiranite, Pyrrolite gear |
Collectibles | 44 Aurylenes, 111 chests, 2 Gear Template Crates, 8 Dataloggers |
Free event currency | Oroberyl + permits for Arcane / Liino banners |
Common Farming Mistakes
Ziplining through Aurylenes. As noted, you must walk into the orb. Use your scanner for hidden Aurylenes that distort light.
Skipping the Cloudseeder Station. Players farm chests first and leave Gas for later — but the station produces while you explore. Set it up on entry.
Ignoring Protocol Dataloggers. They look like decorative balloons until you have authorization; once active, they are free AIC Index for the new gas tech.
Racing the boss without interrupts. Alleikhreos requires battlefield-mechanic interrupts; a pure damage race fails.
Missing the two Gear Template Crates in Yinglung Pass. They are the only Tier 5 crate source in the gateway map — grab them on the first pass.
Final Verdict
Yinglung Pass is small but strategically the most important new map in Version 1.4. Unlock it by pushing Chapter II to "Bravely Breach the Hostile Winds," clear it in one efficient loop (TP Points → Aurylenes → Gear Template Crates → Dataloggers → Cloudseeder Station), then dive into the North Wuling Exclusion Zone for its 85 chests and the Alleikhreos boss. Set up Gas production immediately, and you will be ahead of the curve on both gear and factory for the rest of the version.
