Once upon a time in the wild world of Teyvat, the Fontaine Research Institute of Kinetic Energy Engineering Region stood as a haunting monument to sheer madness—a place utterly decimated by a cataclysmic explosion ages ago. Now, in 2025, this forsaken zone is crawling with danger, yet dripping with opportunity for any brave Traveler. Floating Allogravity-Condensed Water Bodies dot the sky like gravity-defying specters, whispering secrets of hidden riches. Holy moly, the loot here is off the charts! Treasure chests stuffed with Primogems lurk in every nook and cranny, but the real jackpot? Forty glorious Hydroculus, ripe for the taking. Talk about a high-stakes game, folks—this ain't no walk in the park; it's an adrenaline-pumping rollercoaster ride through apocalyptic beauty.
The Hydroculus Hunt Begins: Above Ground Chaos
Kicking off this crazy adventure, Travelers gotta teleport to the waypoint north of the Experimental Field Generator boss—an intimidating beast that's nothing to sneeze at. From there, head southwest and—bam!—a teleportation bubble zips you to a hilltop Hydroculus. Why did they put it there? Who knows, but oh well, grab it! 
Next up, scoot north to ruins where a sneaky Hydroculus hides under a stone slab. Easy-peasy, right? But hold your horses—climb a nearby hill southwest for another one. Gotta keep moving fast before things go sideways!
Teleport back to the same waypoint and head south toward the Experimental Field Generator boss. Scale the building ruins like a pro climber to snag the Oculus on the side—totally worth the sweat! Then, glide from a mountain peak to a tower's highest point—epic views, insane thrills! But wait, there's more: use the southeast waypoint and spot a Hydroculus behind a barrier. Find two Seelies to bust it open—piece of cake! Head west into a ground hole, unlock a door with Arkhium Lumenite, and voilà, another Hydroculus. Mind-blowing, I tell ya!

Dive Deep: Underwater Wonders and Hidden Quests
Now for the wet 'n' wild part—teleport to the east waypoint near the Statue of Seven and head north to a Hilichurl camp. Between machine claws? Yep, a Hydroculus chillin' there like it's no big deal. Glide from the statue to a broken highway—careful on that shaky ground! Then, plunge down south for one between pillars. But oh boy, things get real underwater. At the Central Laboratory Ruins, dive into a Condensed Water Body—swim straight to a window ruin for a Hydroculus. Crazy, huh? Hop on top of another water cube, climb floating debris for a high-altitude grab. Glide east to a highway end—another one bites the dust!
Dive deep again and spot an Echoing Conch—use a Xenochromatic Blubberbeast's ability to hit a crystal, unlock a gate, and swim in for the prize. Holy guacamole, that's some next-level puzzle-solving! But hold up—start the 'Treacherous Light of the Depths' quest underwater to access another Hydroculus in the ruins. Talk about a hidden gem—literally!
| Location | Action Required | Hydroculus Count |
|---|---|---|
| Hilichurl Camp | Glide from statue | 1 |
| Underwater Ruins | Swim and unlock gate | 2 |
| Condensed Water Body | Climb debris | 1 |
| Hidden Quest Start | Complete 'Treacherous Light' | 1 |
Final Stretch: Ruins, Caves, and Epic Rewards
Teleport to the New Fontaine Research Institute waypoint—climb to the second floor and glide to a banner center for a Hydroculus. Out of the blue, head northeast between broken roads—another one just sittin' pretty. Spot a Hydro Amber? Destroy it, and a bubble teleports you to an airborne Hydroculus. Glide northeast under building construction for a tight-space grab. Jump south to lower ruins—easy as pie! Teleport back, head west, and climb rocks for yet another.
Use the north waypoint—head northeast to the map edge for an Oculus. Climb a mountain top southeast to find a Luxurious Chest and Hydroculus side by side—jackpot! 💎 Glide southwest to a tower peak—final one in sight. But oh snap, teleport northwest and head west to a pier top. Return to the waypoint, follow east to a cave, and start the 'Road to the Singularity' quest. In the cave center, a mechanism holds a Hydroculus—unlock rooms, and it's yours! Jump down south, dive into a sea tunnel, and grab the last Hydroculus. Piece of cake? Nah, more like an epic grind!
