How to complete the Shitoki’s Treasure Map Hidden Objective in Genshin Impact

Tsurumi Island's story doesn't end with Ruu. After completing The Sun-Wheel and Mt. Kanna, players can unlock a series of Hidden Exploration Objectives—one of which involves solving the puzzle of Shitoki's Treasure Map.

To complete this Objective, you need to search for glowing blue conches around Tsurumi Island. Some of them will merit you random items; others, a Quest Item. While there are plenty around the island, there are only four key conches you need to pick up in the locations circled below.

It's important to start in the area beside the Waverider Waypoint. Picking up the conch will prompt an illusion of Shitoki in distress. Shitoki will speak about having been left a treasure in the conches by his brother, but they have been scattered around the island.

Each conch will give you a Quest Item: Treasure Map Fragment. If you don't receive this item, then you must have interacted with the wrong conch, so try searching within the vicinity of the circled areas in the map above.

After collecting all four, head to the cliff by the Statue of The Seven, where you'll find an illusion of Shitoki. Speak with it, and you'll receive the Quest Item A Treasure Map Left for Shitoki.

You can open the map in your Quest Item Inventory. It indicates a marked area, which is located deep inside Mt. Kanna. With that said, head to Mt. Kanna and fly downwards in the cave. This is the same spot where you last saw Ruu.

There's a Dig interaction beside the Thunderbird Statue. Interacting with it will prompt a Precious Chest to appear, along with Big Brother's "Letter," which you can read but can't pick up.
