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 the collection of four Burning Firestones to acquire the Jade of Return.

How to Obtain the Four Burning Firestones

Burning Firestone #1

The first Burning Firestone is obtained automatically after the cutscene with Bona concludes. The Little One will collect it, leading you to a bridge. Activate the nearby mechanism to raise the lift, interact with the Saurian, speak with Bona, and watch another cutscene.

Burning Firestone #2

The second Burning Firestone is located on the northeastern isle. To reach it: Rotate the right and left floating isle mechanisms, cross the extended bridge, raise the lift, and follow the Little One. Along the way, collect a Common Chest. Activate the mechanism to the right of the Firestone, climb the spawned platforms, defeat an enemy, and collect an Exquisite Chest. Activate the mechanism behind the chest to open a gate, descend to the Saurian, open the locked door, and tell the Little One, "Let's return to the altar!"

Burning Firestone #3

To acquire the third Burning Firestone: Rotate the right and northern floating isle mechanisms, cross the bridge to the northern isle's lower level, and follow the Little One. Observe a Secret Source Sentinel carrying the Firestone to the southwestern isle. Proceed to the northwestern edge, inhabit a Qucusaurus, fly to the Pyroculus, activate the tower mechanism, transform into a Qucusaurus again, fly to the unlocked door, activate the elevator, interact with the Saurian, follow it, activate the lift, and return to the Altar of Primal of Flame.

Burning Firestone #4

The final Burning Firestone resides on the northwestern isle's upper level. Cross the northwestern bridge, request Bona's assistance to raise the bridge, glide to the northern isle's upper level, lower the lift, and follow the Little One. Tell it, "Let's return to the altar!", defeat the spawned enemies, and ask the Saurian again to return to the altar. Collect a Precious Chest before reaching the Altar.

Offering all four Burning Firestones to the Altar completes The Flowing Primal Flame Quest, triggering a cutscene where the Jade of Return transforms into a Golden Entreaty. The Dragon of the City of Flowing Ash then appears, continuing the journey. Follow the Taunted One to the Nursery of Nightmares to finish The Other Side of the Sky Quest and receive 50 Primogems.
