The transition between floors was usually a gradual descent—a change in temperature, a shift in the stone, a slow thickening of the air.
This was not gradual.
The moment they stepped off the stairwell, the atmosphere hit them like a physical wall. It wasn't just pressure; it was *weight*. The mana in the air was so dense it felt viscous, like trying to breathe while submerged in warm water.
Fen staggered, clutching his chest. "The mana... it's too rich. My detection spell is oversaturating. I'm getting echo readings everywhere."
Cas grunted, planting his shield firmly on the ground. "Feels like we're walking through soup. Is this normal for floor four?"
"No," Maren said immediately. She looked around, her eyes sharp, but her brow furrowed in confusion. "Floor four is the Fungal Gardens. It's supposed to be humid, spore-heavy, low visibility. This..."
She gestured to the cavern ahead.
It was open. Vast. A cathedral of dark stone that stretched upward into a void of shadows. There were no glowing mushrooms, no soft carpets of moss. Just grey, jagged rock and a silence so heavy it rang in the ears.
Haruki moved to the side, his hand resting on the crude crystal sword at his belt. Without Sol's mapping or Rax's radar, he was relying entirely on his eyes. And what he saw on the ground made him pause.
Footprints.
Huge ones.
They were pressed into the solid stone as if the rock had been mud when the creature passed. Three-toed, deep gouges where claws had gripped for traction. The stride length was massive—nearly three meters from heel to heel.
He crouched, running his fingers over the edge of a print. The stone was smooth, cooled from the friction of whatever had made it.
"Wick," Haruki said, his voice low. "What makes tracks like this on floor four?"
Wick limped over, adjusting his pack. He looked at the tracks, then paled.
"Nothing," Wick whispered. "Floor four has vermin. Giant centipedes, spore-crawlers. Nothing heavy enough to leave gouges in solid rock. And certainly nothing with three toes."
Haruki stood up. He looked further ahead, into the gloom.
About fifty meters out, there was a pile of... debris. It was scattered near a stalagmite, glinting with a dull metallic sheen.
Haruki walked toward it.
"Haruki, stay close," Maren warned, but she didn't stop him. She was busy looking at the walls, her staff glowing faintly as she tried to get a read on the environment.
He reached the pile.
It wasn't debris. It was a party.
Or what was left of them.
Shattered plate armor, crushed beyond recognition. A broken staff, snapped in two as if it were a twig. A shield that had been folded in half, the metal screaming from the force of the impact. And scattered amongst the ruin—glinting white fragments of bone.
There was no blood. The pressure had been so sudden, so absolute, that the bodies had simply been compressed.
Haruki felt a cold knot tighten in his stomach.
"Sol," he thought instinctively. "Analysis."
Silence. The empty, echoing silence of his own mind.
He was on his own.
He turned back to the group. "There was another party here. They didn't make it."
Maren hurried over, Cas and the others close behind. She looked at the wreckage, her face grim. She picked up a piece of the shattered shield, turning it over. The crest on it was partially obscured, but the style was distinct—heavy, reinforced, high-tier.
"This is Adamantine plating," she said, her voice tight. "You don't bring this gear to floor four. You bring this to floor eight. Nine."
"Why is it here?" Sable asked, her eyes scanning the shadows with renewed intensity. "And what crushed a tank in Adamantine like a soda can?"
Maren dropped the metal. It clattered loudly in the silence. She stood up, looking at the cavern walls again. Then at the ceiling. Then at the mana density shimmering in the air like heat haze.
"The architecture," Maren muttered. "It's wrong."
"How wrong?" Fen asked, looking nervous. "Wrong like 'trap' wrong, or wrong like 'we're lost' wrong?"
Maren pointed to a distant rock formation, a jagged spire that leaned precariously to the left. "I've studied the maps. I've memorized the terrain layouts for floors one through ten for our recovery runs. Floor four is supposed to be a closed system. Tight corridors."
She spun around, looking at the open expanse, the ceiling lost in darkness.
"This is an open biome," she said. "High ceilings. Wide tactical space. This is the geography of a hunting ground, not a garden."
She closed her eyes, reaching out with her mana sense, testing the density of the air. Her eyes snapped open a second later, fear flashing across her face.
"The density," she whispered. "It's double what it should be. Triple. It's... it's pressing down on us."
She turned slowly, looking at the rest of the team.
And then she looked at Wick.
The young porter was standing still, staring at the three-toed tracks. His face was drained of blood. He was trembling, his one hand gripping his strap so hard his knuckles were white. He wasn't looking at the tracks, Haruki realized. He was looking at the distance between them.
"Wick?" Maren asked gently. "What do you see?"
Wick swallowed hard. His voice came out as a cracked whisper.
"The gap," he said.
"What gap?"
"The stride," Wick said, pointing a shaking finger. "Three meters. That's a charge stride. That's a momentum build-up."
He looked up at Maren, his eyes wide with a terror that looked too old for his face.
"I know this place," he said. "I read the incident reports. I studied the 'Do Not Enter' logs when we were prepping for floor nine."
He took a shaky breath.
"This isn't the Fungal Gardens. The mana isn't heavy because of spores. It's heavy because of *predators*. Apex presence."
Maren grabbed his shoulder. "Wick. What floor is this?"
Wick looked at the darkness ahead, where the shadows seemed to breathe.
"We skipped it," he said. "The dungeon... it shifted. The stairwell didn't take us down one level."
He looked at Maren, the realization crashing down on them all.
"This is the Hunting Grounds. This is the floor where the previous party was wiped out."
He swallowed.
"We aren't on floor four. We're on floor five."
The silence that followed was suffocating.
Floor five. The floor they weren't supposed to touch for months. The floor where the ecosystem balanced itself on a knife's edge, and every creature was a killer.
Cas swore softly, his shield raising instinctively.
Maren looked back at the stairwell they had just exited. It was still there, a dark rectangle in the wall.
"Go back," she commanded instantly. "Everyone. Back to the stairwell. Now."
Sable moved first, turning on her heel.
But she stopped.
"The door," she said.
Haruki looked. He had been so focused on the tracks, he hadn't noticed.
The stairwell entrance was sealed. The stone had flowed over the opening like wax, sealing it shut. There was no handle. No seam. Just a smooth, unbroken wall of dungeon stone.
"We can't go back," Sable said, her hand drifting to her batons. "We're locked in."
Maren cursed. She turned back to the vast, open cavern. The heavy air pressed down on them.
And then, from the darkness deep within the floor, came a sound.
*Thump.*
*Thump.*
*Thump.*
Three heavy, rhythmic impacts. Like a heartbeat.
Or footsteps.
Haruki gripped his crystal sword, the red heat in his left hand pulsing in time with the sound. He had no systems. No support. No map.
He was a porter with a glass knife, standing on a floor that wanted him dead, surrounded by monsters that crushed high-tier adventurers.
And the only way out was forward.
