Hidden Palace of Zhou Formula in Genshin Impact is a location in the game that you can unlock and explore if you have a high enough Adventure Rank. However, in order to unlock the Genshin Impact Hidden Palace of Zhou Formula, you first have to solve a puzzle. Needless to say, some players will probably have some trouble figuring out how to solve this puzzle. If you’re one of these players, then our Genshin Impact Hidden Palace of Zhou Formula guide is the right place for you.
How to Unlock Hidden Palace of Zhou Formula in Genshin Impact?
To unlock the Genshin Impact Hidden Palace of Zhou Formula, you have to find and activate four flame “switches,” and then use your Geo on the appropriate pillar. The first step, of course, is to go to its location. You can find this particular hidden palace east of Qingce Village (where the Geo Statue puzzles are) and north of Wuwang Hill. You can find the exact location in the images below.
Once on location, you might want to clear the area of enemies to make your life easier. Either way, it’s now time to find the four flame-activated switches. The first one is right next to the Geo switch, and one more on the ledge right above it. The third one is on the cliff above the large stone block under which the palace lies. Lastly, there’s one across the pond from the first switch, but it’s behind a wind barrier. That’s not too big of a problem, since you can climb onto the large rock next to it and hop inside the barrier. It’ll dispel when you light the fire.
After you activate all four fire switches by attacking them with fire moves, head to the large Geo switch (or pillar, if you will) and use a Geo move on it. This will break the huge stone block, and the Hidden Palace of Zhou will rise from the ground. You can enter it only if you have an Adventure Rank of 22 or above. Good luck!
