Genshin Impact: Undetected Infiltration Quest Guide

Genshin Impact - Undetected Infiltration 1

Genshin Impact’s 2.6 update involves loads of quests for The Chasm region. One of these quests is Undetected Infiltration. In this quest, you come across members of the Millelith posing as Treasure Hoarders. Read on to find out how to complete the Undetected Infiltration quest in Genshin Impact.

How to unlock the Undetected Infiltration quest

For travelers to unlock this quest, head over to an area between Tiangong Gorge and Glaze Peak. When you get to this area, you’ll encounter “Treasure Hoarders” who don’t hesitate in attacking you.

After you defeat them, a cutscene will play wherein the leader of the Treasure Hoarders tells travelers he’s with the Millelith. Yanbo, the fake Treasure Hoarder will tell you to meet him in Lumberpick Valley. A marker on the map will tell you Yanbo’s location. After you arrive at the meet-up location, Yanbo will then employ your help in clearing out two Treasure Hoarder camps in The Chasm.

How to clear out the Treasure Hoarder camps

To get to the Treasure Hoarder camps, look at your map after talking with Yanbo. Then, you can see quest markers indicating the two camps Yanbo is asking you to take care of. But after you clear out both camps, the quest will make you go to a larger camp where you’ll fight off even more Treasure Hoarders.

Bring a DPS-focused team for the larger camp

For this last Treasure Hoarder camp, it’s recommended you use a high-DPS team because the Treasure Hoarders will come in waves. Other than that, you will also battle two elite Treasure Hoarders: Brass Bull Zhao and Chen the Flower.

Report back to Yanbo after you finish clearing out the last camp.

  1. Even if I defeated those treasure hoarders, there’s no quest that appeared😭 idk what to do. Btw, my adventure rank is 28, is it possibly because of my rank?

      Hi, Ame! Don’t worry, it’s not because of your Adventure Rank. You need to finish the Surreptitious Seven-Star Seal Quest first so you can unlock this quest. Unfortunately, not finishing this quest will not trigger the required cutscene between the Traveler and Yanbo.

      You can check out our guide on that quest so you can finish it quickly. 😁

      Ad astra abyssosque, fellow traveler! ✨
