Once you’re down in the Underground Mines under the Chasm, there will be puzzles waiting for you to solve in the form of mechanisms. As part of the Heavenly Stone’s Debris quest, you will need to activate the Mountainator, for which you have to figure out what the lamps do. This guide will take you through the process of how to set the Lamp Frequency for the Mountainator in Genshin Impact.
How to Get the Mountainator Ready to Fire in Genshin Impact
As part of the quest, you will need to release the safety mechanism on a massive cannon called the Mountainator, and change the frequency of three different lamps that are in the Underground Mines in Genshin Impact. At the start of the quest, you will receive a book that has instructions on what to do for this quest which is called the Safe Blasting Device Signalling Guide—but honestly, why would you read a book in the game when you can just read a guide? We have all the details here for you in a cohesive form that is easy to digest.

You will need to interact with the lamps that the game shows you when you observe the area. Glide down to the first one and activate it on a low frequency by interacting with it once. Glide down again, to the second lamp in the distance which is indicated by the purple Viewpoint and interact with it twice to set it to the correct frequency. For the third and last one, you will need to glide down to the purple sludge and get rid of it. There is a Whopperflower that will try to attack you, and you will need to kill it to move on with your task. Interact with the lamp twice and it will be set to the correct frequency which is high.
Follow the new waypoint up to the Mountainator, which you can easily operate and aim, after loading it with a cannonball with the help of Zhiqiong.
