Honkai: Star Rail All Treasure Chests in Penacony (The Reverie – Dreamscape)

The Reverie (Dreamscape) is the - currently - largest area in Penacony with the most number of treasure chests and puzzles.

The Reverie (Dreamscape) is the - currently - largest area in Penacony with the most number of treasure chests and puzzles. You can look at the official interactive map here to see the full layout and position of the chest (of course, this 3D map is also available in-game). In total, there are 48 treasure chests in this area, including puzzles and Lordly Trashcans. But I will not include the 12 treasure chests that you will get from the Adventure Mission 'Slaughterhouse.'
While doing the guides, the official interactive map didn't fully update so there are multiple pins that are not marked yet. So I edited the images and added red circles (#10, #11, #32, #33, and #48).
