Genshin Impact: How To Collect The Burning Firestones (The Flowing Primal Flame Quest)

In Genshin Impact, after assisting Bona in purifying the Abyssal Corruption from the Chu'ulel Light Core, players must help her locate the Primal of Flame. Once found, Travelers must offer two Pyrophosphorites (obtained during the Palace of the Vision Serpent Quest) to the Altar of Primal of Flame.

This offering opens a path to Tonatiuh, a floating island above Ochkanatlan’s Cradle of Fleeting Dreams. Reaching Tonatiuh completes the To the Sky-Road Quest and begins The Other Side of the Sky Quest, requiring Travelers to gather four Burning Firestones to acquire the Jade of Return.

Acquiring the Four Burning Firestones:

Burning Firestone #1:

The first Firestone is obtained automatically during a cutscene after reaching Tonatiuh. Follow the Little One across the bridge (activating a lift mechanism) and interact with the Saurian and Bona.

Burning Firestone #2:

The second Firestone is on the northeastern isle. Activate the right and left floating isle mechanisms to extend the bridge, raise the lift, and follow the Little One. Collect a Common chest along the way, activate the mechanism near the Firestone, climb to the upper level, defeat an enemy, and collect an Exquisite chest. Activate the mechanism to open a gate, descend, open a locked door, and return to the Altar with the Little One.

Burning Firestone #3:

To obtain the third Firestone, rotate the right and northern isle mechanisms, cross the bridge to the northern isle’s lower level, and follow the Little One. Observe the Secret Source Sentinel carrying the Firestone to the southwestern isle. Inhabit a Qucusaurus, fly to the Pyroculus, activate the tower mechanism, fly to the unlocked door, use the elevator, interact with the Saurian, activate the lift, and return to the Altar.

Burning Firestone #4:

The final Firestone is on the northwestern isle’s upper level. Cross the northwestern bridge (using Bona to adjust it), glide to the northern isle’s upper level, lower the lift, and follow the Little One. Return to the Altar, defeat an enemy, collect a Precious chest, and finally, reach the Altar of Primal of Flame.

Offering all four Firestones to the Altar completes The Flowing Primal Flame Quest, transforming the Jade of Return into a Golden Entreaty. The Dragon of the City of Flowing Ash then appears, leading players to the Nursery of Nightmares to complete The Other Side of the Sky Quest and receive 50 Primogems.
