World Quest: Surreptitious Seven-Star Seal Sundering
Talk to Muning and find out the situation in The Chasm
To start the quest, A player need to speak with NPC (Muning) to find out the situation of the chasm. Talk to him and accept the commission. You can find Muning near the eastern teleport waypoint of Chasm.
Look for the adventurer Zhiqiong
After speaking with Muning, head northwest to meet another NPC (Zhiqiong). She will tell that If you wish to enter The Chasm, we first need to find an Adjuvant made from a material known as Lumenstone. Only with it can we move in the dark down there. It’s in a warehouse to the south. The warehouse is well-guarded.
Go to the miners’ warehouse
Go to the miner’s warehouse which is located south of the current location.
Fend off the Treasure Hoarders
Eliminate all the treasure hoarders from the area.
Obtain the Lumenstone Adjuvant
Next, go inside the miner’s warehouse to collect the Lumenstone Adjuvant, placed on a table. Finally report back to Zhiqiong.
Look for a way to destroy the Bedrock Keys
Now obtaining Lumenstone, Zhiqiong willinform you that as per Liyue Diaries on the Chasm, the Bedrock Keys are Magical Arrays set up by the Liyue Qixing to prevent entry into the Chasm. They will need to be dispelled or destroyed to continue exploring further.
After reaching the location, you will find two Cage-Shaped Geo Formations floating over the large stones of the Bedrock Keys. Break the crystal rocks at the bottom of the boulders to collect Geogranum, then place the Geogranum on the Cage-Shaped Geo Formations. It is recommended to use a claymore character to break rocks crystal fast. Refer to below image.
After you’ve placed the Geogranum on both floating Cage-Shaped Geo Formations, you must hit those Geo Formations for it to discharge a beam out.
Finally, to destroy the Bedrock Keys, you must aim the beam such that it hits the Bedrock Keys while you hit the Geo Formations.
Look for a way to destroy the three remaining Bedrock Keys (0/3)
To complete this objective, you need to place Geogranum on three different cage-shaped floating objects and then hit these objects to shoot a beam on Bedrock Keys. All three locations are already marked on the map.
Bedrock Keys (1/3)
Head to the first marked location on the south-eastern side as marked on the map below. Here three cage-shaped objects are there and you need to start from the one placed on top of the mountain/cliff and then descend to other structure. It is recommended to use a claymore character to break rocks crystal fast.
#1: On Top of a Mountain near Mechanical Structure
First, break the yellow crystal rock lying on the wooden platform of the mechanical structure to collect Geogranum.
After collecting Geogranum, drop down and glide to land on the wooden lift directly below the wooden structure. Put the Geogranum as the wooden lift reach near the cage-shaped object
After you’ve placed the Geogranum, hit the cage-shaped object to discharge a beam out. You have to aim the beam such that it hits the Bedrock Keys. As the beam hit the Bedrock Keys it lowered down.
#2: Near Mountain Cliff
Similarly, break the yellow crystal rock to collect Geogranum. Use the wooden lift to place Geogranum on the cage-shaped object. Hit the cage-shaped object to discharge a beam out that will hit the Bedrock Keys. As the beam hit the Bedrock Keys it lowered further.
#3: Inside the hut.
Finally, to destroy the Bedrock Keys, drop down to the bottom. Break the yellow crystal rock near a group of enemies miners to collect Geogranum.
Head inside the hut to place Geogranum on the cage-shaped object. Hit the cage-shaped object to discharge a beam out that will hit the Bedrock Keys. This will destroy the first Bedrock Keys
Bedrock Keys (2/3)
To destroy the second Bedrock Keys, you need to place Geogranum on four different cage-shaped objects. All these cage-shaped objects are located at different elevations, so you need to start from the top and keep going down to destroy the Bedrock Keys. The process is the same also. Collect Geogranum from nearby rock crystals and placed it on the cage-shaped object. Hit the cage-shaped object to discharge a beam out that will hit the Bedrock Keys. Refer to the below images for reference.
Bedrock Keys (3/3)
To destroy the second Bedrock Keys, you need to place Geogranum on three different cage-shaped objects. The Bedrock Keys is inside a cave just below the big yellow crystal rock in the area “The Surface”. I have marked the location below on the map. Enter the cave to find Bedrock Keys
The first cage-shaped object is on the left side after you exit the narrow cave passage to reach a bigger area. The process is the same also. Collect Geogranum from nearby rock crystals and placed it on the cage-shaped object. Hit the cage-shaped object to discharge a beam out that will hit the Bedrock Keys. This one will lower the Bedrock Keys first.
The Second cage-shaped object is after the first wooden bridge not very far from the previous one. This one will lower the Bedrock Keys a second time. Finally report back to Zhiqiong.
The third and last cage-shaped object is at the bottom. Finally, to destroy the Bedrock Keys, you must aim the beam
Look for the final Bedrock key
Zhiqiong (NPC) will as ask you to break the final Bedrock key to break the barrier. The final Bedrock key is located inside a cave in the Cinnabar Cliff area. The location is marked on the map below, from the nearest teleport waypoint north and then drop down the cliff. Glide down to the location and enter the cave with a rail track.
At the end of the cave, you will find the last Bedrock key and two cage-shaped floating objects. First, break the yellow crystal rock to collect the Geogranum. It is recommended to use a claymore character to break rocks crystal fast. Place Geogranum on the cage-shaped floating objects and then hit it to shoot a beam on Bedrock Keys.
After that, drop down inside the cave and do the same process with other cage-shaped floating objects to shoot a beam on Bedrock Keys.
Quest will end, once you successfully hit the Bedrock Keys with a beam coming out of the cage-shaped floating objects. A cut scene will play and the that will break the seal of the Chasm.
