Ruin Machine Core in Genshin Impact: How to Find and Restart

In Genshin Impact Ruin Machine Core is a key item to unlock achievements “Unhidden source of backup power”, since it is with the help of it that it will be possible to restart the Ruin Guard in the Chenyu Valley. By doing this, you will gain access to the cave that contains spiritual carp. In this guide, we will tell you where you can find this part and how exactly to use it.

How to unlock the "Unhidden Backup Power Supply" achievement

Ruin Mechanism Core Location

Head to the gorge located in the northern part of the Chenyu Valley. Run up the path until you see a locked rich chest. Next to them will be automatons.

Let us remind you that these opponents have high resistance to physical damage, but are also quite vulnerable to elemental attacks, so we advise you to use various reactions against them (Steam, Melt, Elemental Reaction: Frozen and Stimulate work best).

Having dealt with the enemies, take the contents of the rich chest and examine the white light that will appear next to the chest. As a result, you will receive the Ruin Machine Core.

Now you need to find the Guardian of the Ruins for whom this core is intended. From your current location, go down a little south until you see a ravine to the right of the road. Looking down, you will see the automaton you need.

Approach the robot and insert the core you found earlier into it. This will trigger the Mossy Statue mini-boss. We are talking about a slightly enhanced version of the usual ruin guard, so use the same battle tactics against him. You will also receive the desired achievement.

Having dealt with the enemy, go down deep into the opened cave. There, pick up the spiritual carp hovering above the jug and deal with the group of treasure thieves. They will be led by "Mount Kan" (a slightly enhanced thug).

After dealing with your opponents, take the treasures from the chests, and then chat with the strange merchant in the cage. After which the man will run away in an unknown direction.
