I still remember the day I first entered The Chasm. The map had teased me since the early beta days, a slumbering scar on Liyue’s southern edge, and now it was finally breathing. But the moment I stepped near that thrumming seal, the world seemed to slow down, and a quest prompt appeared: Surreptitious Seven-Star Seal Sundering. Among its tangled steps, one objective jabbed at my patience like a splinter beneath a fingernail — “Look for a Way to Destroy the Bedrock Keys.” The massive floating Geo constructs hovered above the terrain like judgmental gods, their heartbeats pulsing in the stone. I had no idea that cracking them open would feel like solving a riddle written in ancient braille with a mallet.

At first glance, the Bedrock Keys looked impenetrable — giant, floating crystals wrapped in what seemed like indestructible armor. But the environment held the answer, whispered in the form of those strange Cage-Shaped Geo Formations scattered around like discarded birdcages from a colossus. My instinct screamed to batter the keys directly, but every swing of my claymore only sent futile sparks into the air. That’s when I noticed the Glowing Geogranums nestled nearby, pulsing with the same golden light that once guided me through Liyue’s earliest trials.

Geogranums are peculiar things — they resemble calcified fireflies caught in amber, and breaking them releases a wisp of petrified sunlight that seeks out those cage-like structures. I summoned Ningguang, her Geo energy resonating with the ore, and shattered a Geogranum with a few precise strikes. The light fled from the wreckage and burrowed into the nearest Cage-Shaped Formation, making it hum with readiness. I realized then that these formations were not just scenery; they were siege engines, dormant until fed.

With the light now inside, I approached the cage and struck it with a charged attack. A crystalline projectile, sharp as an accusation, launched out and arced toward the Bedrock Key. The first shot missed, hissing past it like a scorned serpent. I adjusted my angle, making sure I was facing the key directly — the formation seemed to vomit its payload in the direction you faced. After a few more hammers of my blade, the projectile finally collided. A thunderous crack echoed through The Chasm as the key fractured, raining shards of light down like shattered chandelier crystals.

One down. I scanned the surroundings for the next, heart racing with the thrill of an archaeologist disarming a primordial trap. Each key required the same dance: find a Geogranum, harvest its soul, feed it to a cage, and then batter the cage into a crossbow. The process became a rhythm, a percussive dialogue between my weapon and the land. However, one key proved to be a mischievous phantom. It was supposed to be in the open, yet all I saw was barren rock. A quick consultation with the adventurer’s handbook revealed it had buried itself like a mole crab in an underground hollow, hidden beneath the earth’s skin.

The path to this subterranean key was intertwined with the Lost Valley Artifacts Domain, a place I had already unlocked while chasing an elusive artifact set. Navigating those tunnels felt like sliding down a sleeping dragon’s throat — damp, narrow, and lit by bioluminescent fungi that clung to the walls like forgotten constellations. Once I reached the underground chamber, the missing key glowed in the center, a silent sentinel waiting for its execution. Beside it stood the familiar cage formations and Geogranums, as if the very earth had decided to replicate the puzzle in its own dark belly.

I repeated the ritual: break the Geogranum, absorb the light, strike the cage until it spat out crystal vengeance. The underground key shattered with a satisfying chime, and the final seal on The Chasm’s surface crumbled. A deep rumble traveled through the stone, and for a moment I felt like a locksmith who had just sprung open the planet’s secret door.

Looking back, the whole task was less about brute force and more about learning to read the terrain’s odd language. The Bedrock Keys weren’t obstacles; they were gigantic padlocks, and the Cage-Shaped Geo Formations were the keys — but only if you knew how to turn them. I still chuckle at how my initial frustration melted into awe. This quest, lodged in Genshin Impact’s 2022 update, remains a testament to how Teyvat’s puzzles reward patience over aggression. Even in 2026, guiding friends through this seal-breaking ceremony fills my adventurer’s journal with the same giddy disbelief: who knew that breaking bedrock would require a conversation with light itself?

Once the seal was fully broken, the map unfolded a new layer — the Underground Mines, a sprawling, map-specific labyrinth that truly defines The Chasm’s scale. If you haven’t yet ventured there, take my advice: listen to the stones, respect the Geogranums, and always, always face your target before swinging.
