The Treasure Thief quest line sits inside the Nuoding City Capital Area, the most concentrated chest and exploration zone in Soul Land: Awakening World. Completing it ties directly into the area’s 20 hidden chests, which feed exploration rewards and progression materials. The work centers on tracking down those chests across the Capital Area and clearing the route that links them together.
Quick answer: Stay inside the Nuoding City Capital Area, locate all 20 chests along a single sweeping route, and open each one. Your exploration meter for the Capital Area fills as chests are claimed, confirming progress.

Where the Treasure Thief quest takes place
The activity is contained within the Nuoding City Capital Area, which is one slice of the larger Nuoding City Region. This distinction matters because the wider region also includes the Nuoding Plains and the Sky Soul Mine, and chests in those zones do not count toward Capital Area completion.
Nuoding City itself appears on the broader Douluo Continent map alongside locations such as Aster Forest, Saint Village, the Icebound Forest, and the Isle of Poseidon. Within the Capital Area, the chests are spread across streets, corners, and tucked-away spots that reward thorough exploration rather than fast travel between obvious markers.

The Capital Area holds exactly 20 chests. Some sit in plain view, while others count as hidden chests that require checking less obvious corners. Collecting every one is what closes out exploration for this part of the map.

How to clear the chest route efficiently

How to confirm completion
Completion shows through the Capital Area exploration progress, which climbs as each of the 20 chests is opened. When the count reaches 20, the exploration rewards for the zone unlock and there are no remaining chest markers inside the Capital Area.
Note: If your exploration percentage stops short of full, the missing chests are almost always hidden ones in less-traveled corners of the Capital Area, not in the surrounding Nuoding Plains or Sky Soul Mine. Revisit the spots you passed quickly before assuming a chest is bugged.
Soul Land: Awakening World is the first 3D open-world MMORPG in the Soul Land saga, published by 37GAMES for Android, iOS, and PC. You can pick it up through the official Steam listing if you want to chase Nuoding City’s chests on PC, then move on to the region’s other exploration zones once the Capital Area is fully cleared.
