Completing Genshin Impact's "Vaulting the Wall of Morning Mist" quest automatically triggers the "Adventure in the Land of Mists" quest. This 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, players must defeat Tenebrous Mimiflora before activating a mechanism to finish "Adventure in the Land of Mists," subsequently unlocking the "Palace of the Vision Serpent" quest. This quest requires purifying the Abyssal Blight within the Core of Chu'ulel.

Purifying the Abyssal Blight in the Core of Chu'ulel:

To cleanse the Abyssal Corruption, follow these steps:

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 section.

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 using the elevator.
7. Retrieve the previously placed Radiant Fragment.
8. Place it on the southwestern Radiant Pillar.
9. Head east.

Next:

1. Use the Rust-Spotted Key to unlock the mechanism and remove the seal.
2. Collect the two Radiant Fragments behind the unsealed 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 mechanism to open the door.

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

This clears the Abyssal Blight, dropping the Chu'ulel Light Core.

Continuing the "Palace of the Vision Serpent" Quest:

1. Protect the fallen Light Core from enemies.
2. Return to Bona at the Cradle of Fleeting Dreams fortress.
3. Speak with Bona.

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