In the Genshin Impact 2.1 update, players will find multiple challenging puzzles across the recently added Seirai and Watatsumi Islands. One of the unique landmarks that Genshin Impact players can find on Seirai Island is a beached ship broken in half located on the west coast called the "Seiraimaru." What players may not know is that the other half of the ship is found in a hidden cavern underneath the Seiraimaru and contains a Relay stone puzzle inside.
Where to Find the Relay Stone Puzzle
To find the puzzle, head to the "Seiraimaru" ship on the west coast of Seirai Island. When players have reached the ship, head east to find a Fatui camp nearby. At the Fatui camp, players will find a large hole next to the camp that leads to an underground cavern containing the other half of the ship, and the Relay Stone puzzle.

How to Solve the Relay Stone Puzzle
Once inside the cave, start by heading through the phase gate on top of the ship, to reach the breakable rocks on the ledge above. Break the rocks to reveals a second phase gate and a Relay Stone.
Pick up the Relay Stone and glide back down to the ship. Place the first Relay Stone next to the protruding metal square on the deck of the ship.
After placing the first relay stone, head back through the phase gate to reach the previous ledge. Once on top of the ledge, interact with the Electrogranum plant nearby.
With the Electrogranum plant, climb the cliff to the east and proceed towards the Electro bubble in the distance. With the Electrogranum plant, players should be able to pick up the second Relay Stone inside the bubble.
Head back to the deck of the ship and place the second Relay Stone on the opposite side of the first stone. Once the second Relay Stone has been placed, players should have two stable connections between the two Discharge Stones and Relay Stones.
Go through the phase gate one final time and interact with the Electrogranum plant on the ledge. With the Electrogranum plant, head west to obtain a third Relay Stone from another Electro-bubble.
From the ledge where the third Relay Stone is obtained, glide down towards the ship and place the stone between the two broken halves of the ship. This can be a little tricky and may require multiple attempts to get the stone in the correct position.
Once the stone has been correctly set, a Luxurious chest will be unlocked in a nearby room. Players should take caution as there are several enemies that will spawn around the chest before they are able to claim it.
Genshin Impact is available for Mobile, PC, PS4, and PS5, with a Switch version in development.
