Completing Genshin Impact's "Vaulting the Wall of Morning Mist" quest automatically unlocks "Adventure in the Land of Mists." This quest continues the journey with Bona to locate the Altar of Primal Flame.

Bona guides the Traveler to the Cradle of Fleeting Dreams fortress in Ochkanatlan's northwest. Here, defeat the Tenebrous Mimiflora ambush before activating a mechanism to finish "Adventure in the Land of Mists," triggering the "Palace of the Vision Serpent" quest. This quest requires purifying the Abyssal Blight within Chu'ulel's Core.

How to Purify the Abyssal Blight in Genshin Impact

To cleanse the Abyssal Corruption:

1. Retrieve the Radiant Fragment from the platform.
2. Place it on the nearby Radiant Pillar to dispel the Abyssal Blight.
3. Defeat the spawned enemies.
4. Proceed to the Core of Chu'ulel: Interior's northern area.

Next:

1. Obtain the Radiant Fragment near the broken bridge.
2. Place it on the adjacent Radiant Pillar.
3. Descend through the floor opening.
4. Acquire the Rust-Spotted Key from the library (near a jar).
5. Activate the elevator mechanism.
6. Ascend via the elevator.
7. Retrieve the previously placed Radiant Fragment.
8. Place it on the southwestern Radiant Pillar.
9. Head east.

Then:

1. Use the Rust-Spotted Key to unlock the sealed area.
2. Collect the two Radiant Fragments behind the now-open wall.
3. Place them on the northwestern Radiant Pillar to activate the elevator.
4. Obtain the Pyroculus.
5. Activate the elevator to descend.
6. Collect the two Radiant Fragments (one from the elevator, one from a nearby pillar).
7. Use the nearby mechanism to open the door.

1. Go southeast.
2. Place the final two Radiant Fragments.

This will purify the Chu'ulel Light Core, causing it to fall. Continue the "Palace of the Vision Serpent" quest by:

1. Protecting the fallen Light Core from enemies.
2. Returning to Bona at the Cradle of Fleeting Dreams.
3. Speaking with Bona.

Quest completion rewards: 50 Primogems, A Nameless Adventurer’s Notes, a Pyrophosphorite, and a Luxurious chest.
