In the Vissudha Field, located west of Vanarana, you'll find an Eremite camp with an Energy Extraction Device that can be diffused with the help of Control Keys. Reference the image below to find the exact location of the Challenge. Since the area is swarming with enemy Eremites, make sure to bring a battle-ready team.

Once you get there, you'll find a mechanism called an Energy Extraction Device. You need to find three control keys to deactivate it.

In this part, you need to find the three missing Control Keys in order to shut down the Energy Extraction Device. You can obtain them in any order.

Second Control Key location

Head to the second layer of the building through the entrance pictured above. Once inside, you'll find the second Control Key by some crates. Approach it to obtain the item.

How to guard the extractor until it shuts down in Genshin Impact

After obtaining all three Control Keys, interact with the Energy Extractor Device at the top of the building to begin a battle segment. A circular gauge will appear above it. Your goal is to stand beside the Device until the gauge above it becomes full. If you're too far away or if there are enemy disruptions, the gauge will stop filling up, so make sure to defeat all the enemies that spawn and stand close to the Device afterward. Once the gauge is all filled up, the Energy Extraction Device will turn off, rewarding you with an Exquisite Chest.
