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 present 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.

Gathering the Four Burning Firestones:

Burning Firestone #1:

The first Firestone is obtained automatically after the cutscene with Bona concludes. The Little One will retrieve it; follow it across the raised bridge (using the nearby mechanism) to a small Saurian. Interact with the Saurian and Bona to trigger another cutscene.

Burning Firestone #2:

The second Firestone is on the northeastern island. Activate the floating island mechanisms (right then left) to extend the bridge. Raise the lift, follow the Little One to the Firestone, collect a Common Chest en route, and activate the mechanism near the Firestone. Climb the spawned platforms, defeat an enemy, open an Exquisite Chest, and use the mechanism behind the chest to open a gate. Descend to the Saurian, unlock the door, tell the Little One "Let's return to the altar!", and return to the Altar of Primal of Flame.

Burning Firestone #3:

To obtain the third Firestone: activate the right and northern floating island mechanisms, cross the bridge to the lower level of the northern island, and follow the Little One. Observe a Secret Source Sentinel carry the Firestone to the southwestern island. Proceed to the northwestern edge, inhabit a Qucusaurus, fly to the Pyroculus, activate the tower mechanism, and then fly to the unlocked door using the Qucusaurus. 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 Firestone is on the upper level of the northwestern island. Cross the northwestern bridge, request Bona to adjust the bridge's angle, glide to the northern island's upper level, lower the lift, follow the Little One, and tell it "Let's return to the altar!". Defeat the enemies, request the Saurian's assistance to return, collect a Precious Chest, and proceed to the Altar of Primal of Flame.

Offering all four 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, leading to the Nursery of Nightmares island to finish The Other Side of the Sky Quest and earn 50 Primogems.
