Arknights: Lung Challenge Guide

Dive into the detailed walkthrough for the “at least 1 operator who is Lung” challenge in Arknights: Endfield!

This photography quest, featured in Carly’s Fairytale of the Valley event (Day 5: “It’s a Lung!”), has left many players puzzled. But don’t worry—we’ll guide you from start to finish.

You’ll find the quest’s precise location along the Cliffside Trail at Originium Science Park.

To maximize your success, we recommend bringing Chen Qianyu, the sole Lung-class operator currently available.

Chen Qianyu, a free 5-star guard obtained through story progression in Endfield Industries, excels in physical damage, crowd control, and inflicting vulnerable status, making her indispensable in this challenge.

This guide covers:

• The best team setup featuring Chen Qianyu
• Step-by-step instructions to complete the quest efficiently
• Details on all rewards, including T-Creds, Oroberyls, and the exclusive portrait frame

Updated for the February 2026 event rerun, this free-to-play-friendly strategy also highlights key tips, common mistakes to avoid, and recommended team compositions.

In the Arknights: Endfield lore, Lung (or “Long” in Chinese) represents a revered dragon-like elder race. These majestic beings boast antler-like horns, serpentine tails, scales, and whiskers, drawing inspiration from East Asian dragon mythology. Unlike Vouivre dragons, Lungs carry significant historical importance within the universe.

Event Spotlight: Carly's Fairytale

This limited-time camera event, running from February 7th to 24th, 2026, unfolds over seven days.

The Day 5 mission, "It's a Lung!", requires a specific photographic composition.

Preparation Checklist

Ensure you've completed the main mission "Chapter I Process II – Paving the Way".

Reach Day 5 within the event timeline via the Event Center.

Have access to the Originium Science Park overworld area.

Confirm Chen Qianyu is in your active roster.

The Perfect Shot: Location & Composition

Fast travel to the Originium Science Park.

Navigate to the Cliffside Trail and seek out a prominent, cascading waterfall.

This scenic overlook serves as your backdrop.

Photographic Requirements

The full waterfall must dominate the background.

Your party must include at least one Lung operator—Chen Qianyu is mandatory.

Your entire 3-operator party must be visible in the frame.

Set the group pose to "Varied" for a dynamic look.

Positioning for Success

Place Chen Qianyu front and center, ensuring her distinctive features are clear.

Position your other two operators to flank her, utilizing varied stances for depth.

Adjust your camera angle so the waterfall fills roughly 70% of the shot behind your team.

Use the preview function to confirm all requirements show a green check before snapping.

Rewards

Submitting the successful photo grants the Day 5 individual rewards.

Completing all seven daily missions throughout the event yields the cumulative grand prize: the exclusive "Carly's Fairytale" portrait frame, along with Orobeyls, T-Credits, Cast Die, and valuable upgrade materials.

A versatile physical damage dealer, Chen excels in teams built to exploit the vulnerable status she applies.

Lungmen Photo Challenge Guide

A fresh approach to Lungmen's trials awaits.

To unlock the full story and claim the thematic 'Carly’s Fairytale' portrait frame, you must complete a specific photographic challenge.

The core requirement is not merely taking photos, but capturing a scene with dynamic composition.

Your subject must be at least one Operator who hails from Lungmen, showcasing them in an active, 'varied' pose against the correct backdrop.

A common mistake is using a static, lineup-style formation.

Ensure your roster filter is set correctly to include only Lungmen operators.

The ideal location is the scenic overlook by the waterfall.

Be mindful of your framing; zoom out slightly to ensure the entire waterfall is in shot, not cut off.

For a smooth run, utilize fast travel to the location and consider an auto-party setup for efficiency.

The rewards for this cumulative task are substantial, extending beyond the frame to include a Cast Die, Advanced Cognitive Carrier, Protoset, and bonus resources.

Free-to-play players can rejoice, as the key Operator, Chen, is unlocked through story progression.

No gacha pulls are required for this event.

For visual confirmation of the exact spot and composition, many have found reference guides online to be invaluable.

Once prepped, the event routine becomes straightforward.

Focus on synergy for future challenges; a built Chen with leveled Agility gear and maxed talents, paired with physical Guards like Snowsant, forms a solid core.

Remember, Orundum is for recruitment, T-Credits for upgrades, and Marks/Inspiration for gearing your team.

Capture Chen Qianyu

To capture Chen Qianyu in the formation, ensure your squad has at least three Operators.

She can be found on a specific ledge near the waterfall in the Cliffside Trail zone of the Originium Science Park.

Access this spot conveniently by using the zipline network.

The quest demands a group photo where Chen, the free 5-star Guard, is clearly present within the team lineup.

Completing this objective grants substantial rewards, including 30,000 T-Credits and a unique frame.

This opportunity is tied to a limited-time event, with a rerun anticipated around February 2026.

Always verify the latest schedule directly through the game's official announcements.

Secure your snapshot to claim the prizes and showcase your progress on Talos-II.
