In the Qingxu Pool region of Liyue, you will discover a puzzle where you can earn a Nameless Treasure.
Qingxu Pool is located at the western side of Liyue, near the border.
Here’s a guide for the Qingxu Pool puzzle in Genshin Impact.
The location of where you can start the puzzle is shown below, marked by the player location (blue).
You will see a stone tablet here. Read it to get clues.
You’ll learn that there are five Geo seals in total. The first Geo seal is just beside the stone tablet.
How to solve the Geo puzzle
To activate the seal, use a character with Geo abilities.
Use a Geo skill / attack to activate the seal. You’ll know it’s activated as it lights up in yellow.
There are four pavilions around this area and all of them contain a Geo seal. Just in front of the stone tablet, you should already see two pavilions.
Enter each pavilion to activate the seal.
Behind the stone tablet area, there are two more pavilions.
Similarly, activate the Geo seals there.
Take the reward
After activating five seals, a Luxurious Chest will fall at the stone tablet’s location.
Open it and you’ll get some items including a Nameless Treasure.
This Nameless Treasure can be sold to an antique shop in Liyue Harbor.
How to sell the Nameless Treasure
You need to actually find two more of these treasures before you can sell (three in total).
Once you have three of them, go to Liyue Harbor and find Linglang, the antique shop owner. She is located beside the jeweler.
Go at night (maybe after 9 pm) and you’ll see the option to sell it to her.
