This guide details how to obtain the four Burning Firestones in Genshin Impact's "The Other Side of the Sky" quest.

1. Reach Tonatiuh.
2. Complete the cutscene with Bona; the Little One will retrieve the first Firestone.
3. Follow the Little One across the bridge (using the lift mechanism).
4. Interact with the Saurian and Bona.
5. Complete another cutscene.

Burning Firestone #2:

1. Rotate the eastern and western floating island mechanisms to extend the bridge.
2. Raise the lift.
3. Follow the Little One to the second Firestone.
4. Collect a Common Chest along the way.
5. Activate the mechanism near the Firestone.
6. Climb the spawned platforms, defeat an enemy, and collect an Exquisite Chest.
7. Activate the mechanism to open a gate.
8. Descend, open the locked door, and ask the Little One to return to the altar.

Burning Firestone #3:

1. Rotate the eastern and northern island mechanisms.
2. Cross the bridge to the northern island's lower level.
3. Follow the Little One; observe a Secret Source Sentinel taking the third Firestone to the southwestern isle.
4. Proceed to the northwestern edge, ride a Qucusaurus, and fly towards a Pyroculus.
5. Activate the tower mechanism, transform into a Qucusaurus, and fly to the unlocked door.
6. Use the elevator, interact with the Saurian, follow it, activate the lift, and return to the altar.

Burning Firestone #4:

1. Cross the northwestern bridge, using Bona to adjust its angle.
2. Glide to the northwestern island's upper level.
3. Lower the lift and follow the Little One.
4. Ask the Little One to return to the altar.
5. Defeat enemies, collect a Precious Chest, and return to the altar.

Completion:

Offering all four Firestones to the Altar completes "The Flowing Primal Flame" quest. A cutscene will transform the Jade of Return into a Golden Entreaty, leading to an encounter with the Dragon of the City of Flowing Ash. Continue to the Nursery of Nightmares to complete "The Other Side of the Sky" and receive 50 Primogems.
