Releasing the safety on the cannon breech in Genshin Impact

Releasing the safety on the cannon's breech is more complicated than it may seem, as players will need to take advantage of the nearby lamp posts and a guide to activate the cannon in Genshin Impact.

They'll need to set certain frequencies to allow the cannon to fire its payload, and the key to the quest seems to be hidden in a nearby book. Gamers will need to utilize these objects properly if they want to progress through this puzzling quest.

1) Read the Safety Manual

To release the safety on the cannon, the first thing that you'll need to do is read the instruction manual. This book can be found on a bench near the objective and is titled the Safe Blasting Device Signaling Guide.

The book will reveal that the cannon operates based on the frequency of the nearby lamp posts. It states that to operate the cannon, the lamp posts must be set to a certain frequency:

• Lowest lamp post: High-frequency flicker
• Middle lamp post: Low-frequency flicker
• High lamp post: Low-frequency flicker

2) Set the frequencies of the lamp posts

To set the frequencies of the lamp posts, you'll need to glide down and interact with them. This will activate them, and you can continue interacting with them to change their frequencies.

All lamp posts are visible from the book's original location and are marked on the map above. They are all positioned near Lumenlamps, making it easier to spot them.

You can easily reach the upper and middle lamp posts by gliding down from the Teleport Waypoint towards the south and southeast.

Once you've activated the upper and middle lamp posts, you can navigate to the final one at the lowest level and activate it. It is located a bit further down the road in the southeast direction.

A Whopperflower will emerge to battle you, but you can take it out with ease or ignore it to finish the puzzle.

Unlocking the cannon is as simple as interacting with the final lamp post again to change its frequency to the highest setting. After this is dealt with, you are free to utilize the cannon to progress.
