It involves sailing to obscure islets around the Golden Apple Archipelago to find treasure left by Ako Domeki and his crew.

To unlock this segment, you first need to find the three Route Logs to unlock The Treasure of the Four Skerries World Questline. The Treasure Clue: Twinning Isle segment will appear in your quest menu. There will be two more quests for the Broken Isle and Minacious Isle, but you can do all three in any order.

How to complete Treasure Clue: Twinning Isle in Genshin Impact

Follow the quest marker to the island northeast of Twinning Isle. You can get there using a Waverider. Once you're there, climb the mountain and speak with the Night Raven. He'll ask you to defeat the Hilichurls inside the cave. Once that's done, attack the four-leaf clover using Anemo inside the cave to spawn a wind current to propel you upward, then speak with the Night Raven again.

The Night Raven will teleport beside the Waverider Waypoint on the islet. Your goal is to sail according to his exact directions. He'll be using rocks to guide your sailing direction.

1. Sail right of the first rock.
2. Sail left of the second rock.
3. Sail through the third rock (use the Waverider Elemental Skill if you get stuck).

For the next set of rocks, you need to make harsher turns.

1. Sail toward the direction of the little fourth rock, then turn left when you pass it.
2. Sail toward the direction of the fifth rock. When you pass it, turn right.
3. Sail toward the direction of the sixth rock circled in the image above. Once you're there, turn right to find your destination.

On the islet, climb the mountain to find a Common Chest. Loot it to get a Quest Item called Ako's Treasure: Location 2. You can proceed with completing the Treasure Clues for the Broken Isle and Minacious Isle in any order. When you're done with those, you can move on to Where the Treasure Dwells.
