Quest Walkthrough
2.Starting the Quest: You'll need to find an old man named Yan'er near the ruins in the Bishui Plain, Liyue. He might not appear on the map, so explore the area around the ruins.
3.Find the Three Fragments: The quest requires you to collect three fragments scattered across Liyue. Here are general locations, but remember, specific spawns might vary or need elemental interactions:
4.First Fragment - Qingxu Pool: Look for ruins or a tower. You might need to climb or glide to reach the area. Use Geo Traveler's skill to create platforms if necessary or solve puzzles involving Geo statues.
5.Second Fragment - Lingju Pass: Near the ruins, there's usually a puzzle involving lighting torches or activating Geo mechanisms. Look for a group of statues or a sealed chest that requires elemental interactions to unlock.
6.Third Fragment - Cuijue Slope: This might involve defeating some treasure hoarders or activating a series of torches or mechanisms with the right elemental abilities. Sometimes these are protected by enemies or require you to solve a time trial puzzle.
7.Open the Vault: After collecting all fragments, return to the ruins where you met Yan'er. You'll interact with a Geo mechanism or a sealed door. Here, you might fight a Ruin Guard or solve another puzzle to finally open the vault.
8.Defeat the Enemies and Claim the Treasure: Inside the vault, you'll typically face some enemies or a mini-boss like a Ruin Hunter or multiple Ruin Guards. After defeating them, you can claim your rewards from the luxurious chest.
