Genshin Impact 4.7: Bedtime Story Treasure Box Locations
Prerequisite Tasks
Adventure Rank ≥ Level 40
Complete the Archon Quest Chapter 4, Act 5: “Dance of the Sinner”

Notes
Once you complete the main storyline dungeon, you can’t enter it again, so don’t miss anything. If you do, you won’t be able to get it later.
Apart from the two treasure chests and four reasoning puzzles in this Archon Quest, you can complete the rest of the tracking quests by just following the storyline.
The two treasure chests are very easy to miss.
You will enter the dungeon shown below when you reach the points [Nonexistent Memory] and [Enter the place where the eye of the Buried Harvester is hidden].
