How to solve the Energy Extraction Device Challenge in Gandha Hill in Genshin Impact

Shut down the Energy Extraction Device in Gandha Hill.

In Gandha Hill, located east of Sumeru City, 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. Approach it to begin a Challenge where you must find two Control Keys to deactivate the Device.

Head to the hill beside the Energy Extraction Device to find a small crack in the building. Upon entering, you'll be locked in. Defeat the Eremites to open the gate leading to the first Control Key. Approach the Control Key to obtain it and open the gate in front of it.

After obtaining all two 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.
