Your Ultimate Guide to the Investigator of Ancient Ruins Quest
Where to Find the Quest

To initiate the quest, navigate to the Fallingstar Fields and encounter a cluster of Hilichurls situated north of the teleport waypoint. Activating this interaction will automatically commence the Investigator of Ancient Ruins quest. Completing this quest is also instrumental for progressing in The Way Into the Mountain quest, as the two are interlinked.
Defeat the Hilichurls

Engage with the Hilichurls and defeat the three foes. Once you’ve vanquished them, a captivating cutscene will pave the way for the introduction of two key NPCs: Nzaya and Kimosi.
Eliminate Abyssal Monsters from the Ruins

After your dialogue with the NPCs, progress towards the ruins and defeat any monsters blocking the entrance. Then, interact with the Tatankasaur Spiritscone. Proceed through the small passage located on the left side of the ruins. Continue until you hit a dead end, where you’ll discover a small opening in the ground, allowing entry into the ruins.

Venture deeper into the ruins and you’ll encounter multiple Hilichurls, alongside Exquisite Chests within a spacious chamber. Defeat these foes and open the chests to summon Abyssal enemies. Fight them swiftly to earn an Exquisite Chest and two Precious Chest rewards.
Engage with the Tribespeople

Finally, exit the ruins and reconnect with Nzaya and Kimosi. This will trigger another cutscene and conclude the Investigator of Ancient Ruins quest in Genshin Impact. As a rewarding conclusion, you’ll receive 30 Primogems for completing the quest, while this interaction will also set in motion the Nahuatzin’s Leap quest, the subsequent chapter in the Chosen of Dragons quest line in Collective of Plenty.
