All Bedrock Keys Locations - Genshin Impact

In this guide, I will share a detailed walkthrough for the Surreptitious Seven-Star Seal Sundering world quest. You need to complete this quest to remove the seal from the Chasm: Underground Mines.

You can talk to Lan (beside Katheryne at Liyue Harbor) to proceed with the quest if you haven’t completed the Archon Quest Chapter 2, Act 3.
