The Chasm in Genshin Impact contains a World Quest series that aids players in its exploration. Home to various mechanisms and the new Ruin Serpent Boss in Genshin Impact, The Chasm: Underground Mines requires a keen eye when navigating its unique terrain. “Heavenly Stone’s Debris” is the fourth part of “The Chasm Delvers” questline and requires them to find two keys to complete the quest.
Players must first complete “The Chasm Charters,” “Surreptitious Seven-Star Seal Sundering,” and “Chasm Spelunkers.” After these requirements are met, players will be able to begin the fourth part of the questline. The first segment of this quest will take place between the Ad-Hoc Main Tunnel and The Chasm: Main Mining Area in Genshin Impact.
“Heavenly Stone’s Debris” begins after speaking to the NPC Jinwu, who is in charge of upgrading the Lumenstone Adjuvant gadget in Genshin Impact. Players will need to find two keys to the gunpowder storehouse. These can be found in different areas of the Underground Mines.

To find the first key, players should take the Teleport Waypoint north of the Underground Waterway. The key will be hidden on top of a water-filtration device opposite a Treasure Hoarder campsite. Players should be sure to have upgraded the Lumenstone Adjuvant gadget to at least level two, as it will be needed to remove the powerful Dark Mud surrounding the device. After clearing the Dark Mud, a pot will appear on top. Breaking it will reveal an Investigation spot that awards players Security Key No. 1 for the “Heavenly Stone’s Debris” quest in Genshin Impact.

As for the second key in “Heavenly Stone’s Debris,” Genshin Impact’s Dark Mud will appear along the way. Players should use the same Teleport Waypoint previously, though they should continue to glide northeast until reaching the dip of the cavern. There will be a bridge guarded by Oozing Concretions. Players will need to glide from the left side of the bridge to the group of Treasure Hoarders. There will be a Dig spot at the end of the footstep trail, which spawns an explosive Geo barrel. Destroying the barrel will reveal an Investigation spot that gives players Security Key No. 2.
Additionally, players can enter the swirling passage to the right of the tent, which prompts the action “Move Up.” Doing so will lead to a caged area with a Luxurious Chest and a lever. Opening the gate with the lever will grant players one of Genshin Impact’s hidden Achievements: “All We Need Is Some Firewood and Some Vinegar…” With the two keys in tow, players will be able to continue their exploration of The Chasm in Genshin Impact.
