[The Desiccated Seabed — 2nd Floor]
The Megalodon had made a fatal mistake: it assumed the shadows were a safe haven. Captain Carod didn't give it a moment to breathe. His mechanical frame hissed as he initiated a system-wide overhaul.
"[TYPE SWITCH: WATER LEVEL 2 — BLIZZARD FORM]!"
The red lightning was replaced by a frigid, crystalline blue aura. Carod slammed his fists into the ground. "AVALANCHE!" A wave of absolute-zero energy surged outward, turning the remaining moisture in the air and the distant horizon of the black ocean into a solid, unmoving block of ice.
Cynthia glanced at the frozen wasteland and then at the shadows beneath their feet. "Saina, Carod... it's swimming in our shadows. You know what you have to do."
"Understand," Saina gasped, clutching her core.
Carod didn't hesitate, switching forms again instantly. "[TYPE SWITCH: FIRE LEVEL 2 — SUN]!"
"I can also help in this!" Ruta roared, his magma-veins glowing with a blinding orange intensity.
The four of them—Cynthia, Saina, Carod, and Ruta—began to charge their thermal energy simultaneously. The intent was simple: erase every shadow in existence.
"This heat... it's just too much!" Techyon gritted his teeth, his Auto-Counter twitching just from the ambient temperature.
Gaia struggled to maintain her shield. "Even inside my barrier, the air is turning to plasma!"
The strain was too great for the already exhausted Saina. Her vision blurred, and she collapsed onto the scorched earth. Fraxy rushed to her side immediately, her green healing light working overtime to keep the girl's heart from seizing in the heat.
Cynthia didn't stop. In fact, she smiled. "If this fish isn't coming out... then I am going in."
Her crimson hair began to flicker, the strands losing their solid form and turning into translucent, White-Hot Plasma. The air around her didn't just burn; it disintegrated.
"[TRUE FORM: SUPERNOVA]!"
The explosion was silent but absolute. The frozen ocean, the rocky terrain, and the remaining mist were instantly vaporized into nothingness. The shadows vanished. With no darkness left to hide in, the Void Megalodon was forced out of the ground, its obsidian scales glowing cherry-red as they began to melt.
"CATCH HIM!" Cynthia commanded, her voice sounding like the roar of a star.
The Megalodon looked around in a panic, seeing the Z Elite closing in from every direction. It let out a high-pitched, vibrating scream as the combined attacks of the party tore into its molten hide.
"He was just running too much," Lapis noted, his Honoured Eyes coolly watching the beast dissolve into ash.
Nefa stood over the remains, her emerald daggers still humming. "Don't let your guard down. That was a nuisance, not a threat. That wasn't the Floor Boss. We still have to find out what actually rules this sea."
As the heat died down, a massive shadow began to rise from the center of the vaporized ocean floor—a structure that looked like a sunken temple.
[The Abyss Floor — The Sunken Temple]
The massive structure groaned as it settled into the bedrock, its walls dripping with black sludge. But it wasn't the architecture that froze the group in place—it was the aura radiating from its gates.
"This is even stronger than me," Cynthia whispered, her white-hot plasma flickering as she instinctively stepped into a defensive stance. "I can feel it... it's not just mana. It's the Void itself."
Yoru closed her eyes, her spiritual senses expanding like a radar. Her face went pale within seconds. "Guys, that's a huge problem," she gasped, "but some other problems are already here!"
Before she could finish the warning, the air screamed.
A massive, obsidian tail—scaled in jagged plates of shadow—swung through the mist with the speed of a railgun. It was so fast that it was invisible to the naked eye. Even Lapis with his Honoured Eyes barely saw the blur.
BOOM!
Cynthia appeared in front of the group in a flash of white light, her arms crossed to block the impact. The shockwave shattered the ground beneath her feet, sending a cloud of dust into the air.
"Yoru, are you okay?" Cynthia asked, her voice tight with the strain of holding back the blow.
The shadows behind the temple began to coalesce, rising like a dark mountain. Out of the gloom emerged a Void Leviathan. It was a serpent of impossible proportions, its body coiling around the temple spires, its eyes glowing with the same murderous red as the eye in the Null Dimension.
"How dare you enter this sanctum..." the Leviathan hissed, its voice echoing like grinding stones. "We are here to destroy you. How dare you challenge us."
Cynthia's eyes narrowed, her white flames flaring up. "Us?"
Captain Carod stepped forward, his sensors scanning the beast. "But it's alone. My radar only shows one biological signature."
The Leviathan's maw twisted into a horrific, toothy grin. "No..."
As it spoke, the darkness surrounding the temple began to ripple and boil once more. New shadows emerged from the ground—not as monsters, but as humanoid shapes. They stepped out of the blackness one by one: a figure holding a spectral shield, another with a familiar bow, and one with the arrogant stance of a fallen leader.
Techyon felt his heart drop into his stomach. The figures emerging from the dark were the distorted, shadow-clones of Goto, Lilia, Kokoi, and Siyo.
"The Echoes," Neweland breathed in horror. "It has harvested their souls."
The silence that followed the appearance of the fallen was broken by a sob of disbelief. Saina stepped forward, her hand reaching out toward the dark silhouette of Lilia.
"Guys... you're alive?" she whispered, her voice cracking with a desperate hope.
"Don't fall into the trap!" Cynthia barked, her white-hot aura flaring as she blocked Saina's path. Her eyes didn't see friends; she saw the hollow, necrotic mana radiating from the figures. "Those aren't your friends. They are shells. If you step closer, they will consume you."
The Void Leviathan let out a low, vibrating chuckle that shook the foundations of the sunken temple. "Enough sentimentality..." the beast hissed. "My friends, do not play with them any longer. Emerge in your true forms!"
The world seemed to tilt. The humanoid shadows of the vanguard didn't just grow; they distorted, their bones cracking and their flesh stretching into impossible, mythic proportions. In the blink of an eye, the dry seabed was no longer a battlefield—it was a nightmare of ancient legend.
From the darkness emerged the Cirein-cròin, its massive sea-serpent coils shimmering with a toxic slime. Beside it, the Hafgufa rose like a living island, its mouth wide enough to swallow a fleet. The jagged, armored hide of Cetus scraped against the bedrock, while the world-circling length of Jörmungandr began to tighten around the perimeter of the canyon. To the left, the twin terrors Scylla & Charybdis manifested—one a multi-headed snapping beast, the other a localized whirlpool of teeth and void. Finally, the Bakunawa ascended, its scales blacker than the abyss, its gaze fixed on the "Sun" Cynthia had created as if it intended to eat the light itself.
Seven legendary world-eaters now surrounded the Z Elite. In the pitch-black shadows beneath their massive forms, hundreds of Red Eyes snapped open, burning with a singular, murderous intent.
Techyon felt the air vanish from his lungs. This wasn't a Floor Boss. This was an execution
