One of the many Abyssal Domains you can find in Genshin Impact is known as the Hidden Palace of Guizang Formula and is packed full of rewards just as you'd expect. Just like the other Abyssal Domains, you aren't free to simply stroll up and enter it right away. Even once you know where to find this specific dungeon, it is protected by one decently cryptic puzzle.
Fear not, adventurer, because no puzzle remains unsolved for long. In this guide, we will show you exactly how to unlock the Hidden Palace of Guizang Formula.

The Hidden Palace of Guizang Formula Location
The first step in solving any puzzle is knowing where to find it, but also when you can find it. This Abyssal Domain won't be available to you until you have reached an Adventure Rank of 30 for the Explore: Voyage to the Sanguine Sky domain and 35 for Explore: Travels of the Moonlit Venturer domain.
Once you're at the appropriate Adventure Rank, find your way over to the Luhua Pool with at least one Pyro character in your party.
The Hidden Palace of Guizang Formula Puzzle Solution
Once you arrive at the ruins in the middle of the lake, you can read some Ruin Writing for a clue as to what the puzzle is you're about to take on. This message reads, "Let anyone who follows in the footsteps of the immortals kowtow before the treasure's gate."
Ahead of you is the magical seal surrounded by several Pyro pillars. Unlike other puzzles in Genshin Impact, the solution here isn't simply to light them all. In fact, you can only activate three of them at a time, so the trick here is knowing which three you need to hit.
The clue is as vague as ever, so don't feel bad if you were left completely baffled as to what to do.
The solution is actually deceptively simple. All you need to do is activate the unbroken Pyro pillars that are in front of the stone pillars surrounding the area. Hit all three and the entire ring will light, the magic seal will vanish, and you can drop down to enter the Abyssal Domain.
