There are many new quests in the latest update of Genshin Impact 2.6 and the players can complete them for lots of rewards. This guide will take you through the process of how to get the secret achievement while completing the Undetected Infiltration Quest in Genshin Impact.
Undetected Infiltration Quest in Genshin Impact: Get a Secret Achievement
Before you start this quest, you will need to be doing the Millennial Mountains world quest, which will automatically unlock this quest for you as you are searching for one of the items. This is a fairly short quest and won’t take much of your time, but there is a secret achievement that you can unlock for some Primogems if you complete this quest.

The first thing you will need to do is make your way to Glaze Peak where you need to defeat some Treasure Hoarders. This will trigger the Undetected Infiltration sidequest, where you will be tasked with talking to an NPC called Yanbo who resides at the Smuggler’s Camp. Once you have found him, you can interact with him to learn about his plans to clear the camps of the Treasure Hoarders. You will be given the task.
Once you have cleared out the three areas he wants, you will need to return to Yanbo who will talk to you about the Millelith. When the dialogue is over, you will be rewarded with 30 Primogems, and the achievement named ‘Well Done, Stierlitz!’ which will grant you an extra 5 Primogems. There are more rewards for you, as you can turn around to open the Precious Chest that has spawned as a result of you completing this quest. Make sure to collect these items as you will need one of them which is a key to unlock something in another quest later.
