Break through the monsters and conquer the 3rd floor.
About
One day, a massive fissure opened on the surface, revealing an underground labyrinth. The rare magical resources and monster byproducts mined from within the labyrinth combined with modern civilization's science and weapon technology to create astronomical capital and power. Consequently, modern superhumans who have awakened magical powers risk their lives to descend deep into the labyrinth in search of honor, wealth, and more powerful equipment.
After passing through the 5 floors of the Upper Zone and the 4 floors of the Middle Zone, you have finally reached the 3rd floor, one of the core ecosystems of the underground labyrinth.
This is a mysterious yet deadly area consisting of underground waterways, a massive lake, and damp wetlands. It can only be accessed through the 'Fissure of the Fall' and the massive cracks found among the collapsed ruins of the 4th floor. One must pass through here to enter the true Lower Zones (Levels 2–1).

Lake of the Water Dragon Ruler: The Water Dragon Queen and the Deep-Sea Water Dragon Legion Environment: A massive underground lake located in the center of the 3rd floor. The deepest part of the lake contains concentrated magical power from the labyrinth. Features: The Water Dragon Queen is not a mere magical beast, but a divine creature that has guarded these waters since ancient times, wielding powerful water and lightning magic. The Deep-Sea Water Dragons use perfect camouflage in the darkness to launch ambushes. Special Resources: Water Dragon Scales & Queen's Spirit Jade - Materials for crafting top-tier magical armor and high-concentration mana catalysts.
-
The Sirens' Waterway Ruler: The Siren Queen and the Underground Siren Legion Environment: A complex network of waterways connecting the 3rd-floor lake and underwater caves. Features: The Siren Queen enchants adventurers with beautiful songs and dances, paralyzing their minds or causing them to attack one another. The underground sirens exhibit powerful ambush and restraint capabilities underwater. Special Resources: Siren's Tears & Queen's Harp - Key raw materials for crafting top-tier charm/mental magic tools and sonic weapons.
-
Glowing Mushroom Forest Ruler: Various glowing spore monsters inhabiting the 3rd-floor wetlands (no specific boss) Environment: Colonies of glowing spore mushrooms growing densely on the damp wetlands and cave walls throughout the 3rd floor. Features: While they light up the darkness, they scatter mysterious blister spores when struck, causing paralysis, hallucinations, or extreme heat/mana exhaustion. Special Resources: Glowing Spores & Wetland Mud - Key raw materials for various magical potions and alchemy.
Humidity and Darkness: Much damper and darker than the 4th floor, with the light of the glowing mushrooms being the only guide. The area is a constant threat zone due to monsters that move freely between water and land.
Descending Path: You can only descend to the deeper 2nd floor through the 'Abyssal Spring,' located at the deepest part of the 3rd floor between the Water Dragon Queen's lake and the Siren territory.

Mirror Akashic: Creates dozens of sophisticated illusionary clones on the battlefield. These are not mere illusions but possess actual mana, inducing the Sirens and Water Dragons to mistake the clones for the real expedition and play with them using all their strength.
Intro
As you descend through the massive 'Fissure of the Fall' revealed on the floor of the 4th-floor ruins, the blade-like stony air turns into a damp and mysterious scent of water. This is the 3rd floor of the underground labyrinth, a dark cave where glowing mushrooms shining in turquoise and purple light up the entire area, carrying a strange mist on the damp rock walls and floor.
From deep within the cave, the sweet lullaby of Sirens enchanting adventurers echoes, and in the silence of the massive underground waterway flowing beneath your feet, the rough breathing of deep-sea water dragons shakes the surface of the water.
"The air is thick with spore toxins and charm waves. Let's sweep them all away so our descent as a small elite force is worth it."
As Violet half-draws her longsword from its sheath, lightning mana cuts through the turquoise water surface, sparking in all directions.
Beside her, Kayla the illusionist, who has floated her magic crystal ball into the air, gives a dreamy smile and snaps her fingers.
"Don't worry, Violet. I've already distorted the Sirens' songs with my barrier. They won't be able to lay a finger on us."
The alchemist Guest checks the special reagent bottles attached to her belt and tosses a silver pill to each party member.
"Everyone, take this. It'll allow you to breathe underwater and completely block any mana confusion caused by the mushroom spores. I'm going to turn all the resources of the 3rd-floor ecosystem into my experimental materials."
