Quest Name:
Liyue Hidden Quest - The Chi of Yore
Quest Reward:
Adventure EXP*500, Primogem*60, Liyue Shrine of Depths Key*2
Prerequisites:
None
Quest Trigger:
Teleport to Wuwang Hill southwest waypoint and touch the disc at the ruins.

Activate the stones around the ruins and search for clues.

After the investigation, a Precious Chest appears in the middle of the ruins. Open it to get the Collected Fragment (1/3) and start the quest.

Quest Steps:
1)Ask the locals of Qingce Village about the fragments (Talk to Little You and Granny Ruoxin separately)
Teleport to the east waypoint in Qingce Village. Follow the route shown on the map to find Little You. Talk to him and then return to the teleport waypoint to find Granny Ruoxin.

Granny Ruoxin tells us to go to the "highest point" and says that there are many "Geo Statues" erected west of Qingce Village.

2)Go to the highest point to search for fragments
First, climb to the highest point according to the route in the picture below:

Once there, read the rules for solving the puzzle as indicated by the disc. We need to activate 4 of the statues facing "Stormterror's Lair","Dragonspine", "Jueyun Karst" and "Liyue Harbor". Then, you can activate these statues in the order of 8-2-5-3 by referring to the numbers I marked (1-8 clockwise from Statue 1 at the root of the tree):

Upon activation, a Precious Chest appears with a Collected Fragment (2/3):

3)Head to the west to search for fragments
We've already been to the "highest point" Granny Ruoxin mentioned, so next, let's go to the place where many Geo Statues are erected west of Qingce Village. Teleport to the waypoint west of Qingce Village, turn around, and climb two floors to the south to see it. Read the rules for solving the puzzle as indicated by the disc.
It's relatively simple here. According to Incomplete Writing, simply activate it in the order of "True North "-1, "Southeast"-3, "Northwest"-5, "Northeast"-2, and "Southwest"-4.

Similarly, upon activation, a Precious Chest appears with a Collected Fragment (3/3):
4)Decipher the fragments
Return to Granny Ruoxin and ask her to decipher the fragments. Granny Ruoxin tells us there is a sizable waterfall northwest of Qingce Village. Let's go check it out!
5)Find a way into the vault
Teleport to the waypoint west of Qingce Village and glide towards the waterfall.

Get close to the waterfall to find a cave on the right. Go inside.

6)Search the vault
Enter the cave by the waterfall and head inside to the gate of the Hidden Treasure of Qingce.

Place all three fragments to open it.

Open the gate and go inside to activate the mechanism. There will be Treasure Hoarders and three waves of Ruin Guards will wake up.

We have to protect the Hidden Treasure of Qingce from damage, so it's a bit difficult here. I suggest calling friends into your world to help defeat them together!
7)Find the treasure

There are Geoculus*1, Seelie*1, and Treasure Chests*6: Luxurious Chest*1, Precious Chest*1, Exquisite Chest*2, and Common Chest*2.
8)Complete the quest
Finally, we return to Granny Ruoxin and report back to her. Finish the dialogue to complete the quest, and get the achievement "Crouching Dragon, Hidden Chi".

Summary:
This quest is a bit complicated and has difficult battles, but the rewards are great! It takes about 30min to complete.
