How to solve the Moontide Sea Puzzle in Genshin Impact
Pioneer Source Structure Location #1
Go to the northern ruins and activate an elevator to go down. Take energy from the cube and activate the sphere next to it, only for it to be an incomplete source structure. It will float up and wait while you deal with the enemy that appeared. Use the elevator to go up and jump through the swarm above you, as these creatures hold the missing piece. Once the Pioneer Source Structure is complete, it will be moved to the center and rest on one of the plinths.
Pioneer source structure Location #2
Turn southwest from the Moontide Sea puzzle into Genshin Impact to see a wandering pioneer source structure moving an ancient lunar gem. Take the energy from the structure to release the energy sphere, then push it to the empty plinth buried underground. A chest will appear as well as a disabled source structure. Take energy from any sphere and throw it at the structure to power it up, moving it to the center to activate another pedestal.
Pioneer Source Structure Location #3
Head to the northeastern ruins for the final structure i Genshin Impact to find an empty pedestal and two patrolling red structures. If you go to the end of the ruins while going northeast, there should be some energy spheres.
You have to push one of them around to the pedestal while avoiding the structures as they will grab the gem.
If you run into a bug and the spheres don't appear where they should, try teleporting to another waypoint outside of Blue Moon, then come back and see if anything spawned. If not, quit the game completely and come back.
Once the sphere is on the pedestal, fly down and open the large chest to find a power source. Take it and throw the energy at the disabled structure to turn it on.
It will go to the center as the last missing structure, completing the Moontide Sea puzzle Genshin Impact.
After the short cutscene, go to the center and use the elevator to go up to see an exquisite chest. If you turn east there is a small floating platform full of spheres. Go there and throw energy at them to reveal a luxurious chest as well as a precious chest.
Additionally, use the nearby portal to travel through the lane and arrive somewhere off the map where another precious chest and common chest are located.
