How to solve the Energy Extraction Device Challenge in Chatrakam Cave in Genshin Impact

Ley Line protection, Sumeru edition.

In the Chatrakam Cave, located north of Sumeru City, you'll find an enemy encampment 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. The glowing yellow part on the top is one control key—you need to find two more to place on the red parts on the left and right of the ring.

Assuming that the Energy Extraction Device is in front of you, turn left and climb the small mountain. Glide toward the top of the building, then jump into the small crevice to reach another part of the building. Defeat the enemy Eremites on the way, then follow the path inside until you find a similar floating yellow item. Approach it to obtain the second Control Key.

After obtaining both Control Keys, interact with the Energy Extractor Device to begin a battle segment. A small energy bar 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.
