In the Light, Beneath the Shadow
Let’s talk about the Bathysmal Vishap Experimental Records lost book in Genshin Impact.
For this one, go to the central area of Dainichi Miroshi. Then, face southwest and go down a couple of ledges until you see a Ruin Guard next to explosive barrels.
Eliminate this foe and blow up the destructible section of the wall.
This will reveal a small room with two Triangular Mechanisms. If it’s Evernight, you can smack the one that has a bluish glow.
Go outside and you should find a Whitenight/Evernight switch next to a challenge marker. Swap to Whitenight and hit the other mechanism.
This opens up the small nook, but you need to swap back to Evernight again. Interact with the wall to reveal glowing symbols. These symbols and their corresponding pips denote the order in which you’d pass through the “spectral doors” in the Serpent’s Heart puzzle area. Do it correctly to spawn a common chest with the book.
All right, let’s discuss the next part of our Genshin Impact Lost Book guide. We’re looking for Hydrological Studies in Byakuyakoku.
Genshin Impact is available via its official website. For more information, check out our guides and features hub.
