Chapter 181: The Living Shield

They swam closer to the Great Tartarus, the golden light above them growing brighter with every stroke. The massive shell loomed ahead like a floating island, its surface covered in ancient moss, barnacles, and trailing tendrils that swayed in the current. Four colossal limbs, like a sea turtle’s flippers, propelled the creature through the water with slow, deliberate grace.

But before they could reach the shell, Gray slowed. His golden eyes narrowed beneath the shadow of his hood.

"There’s something there."

A barrier shimmered around the Great Tartarus, a faint, translucent dome that pulsed with a soft, iridescent light. It was barely visible, like heat haze over water, but Gray could feel it pressing against his senses.

He reached out with one hand and touched it.

The barrier rippled under his fingers, firm but yielding, like touching the surface of a bubble that refused to pop. It didn’t hurt him. It just... pushed back.

"So this creature has a natural shield," he murmured.

Cindy drifted closer, her frills swaying as she studied the barrier with a mage’s eye.

"I can feel the mana in it," she said. "It’s dense. Layered. And it’s not a spell. There’s no structure to it, no incantation." She paused, her silver eyes widening slightly. "This is... this is the Tartarus’s own mana. It’s generating the barrier naturally, just by existing."

Gray’s fingers curled against the barrier’s surface.

"A living creature that generates its own shield. That’s why no one’s ever been able to reach it."

Gray withdrew his hand, studying the shimmering dome with cold calculation.

"Then how do we get through?"

Cindy opened her mouth to answer, but before she could speak, Lily darted forward.

The star creature simply drifted through it, her five points spinning lazily, her dark core pulsing with quiet confidence.

The barrier rippled where she passed, but it didn’t stop her. It didn’t even slow her. It just... accepted her, like water accepting a fish.

"...What?" Cindy whispered.

Lily hovered on the other side of the barrier, her points orbiting slowly, her dark core flickering with what might have been amusement. She turned back toward them, tilting her body as if to say, What are you waiting for?

Gray stared at her for a long moment. Then he looked at the barrier. Then back at Lily.

"...She just went through."

"I saw," Cindy said, her voice faint with disbelief.

Gray pressed his hand against the barrier again, feeling it push back against his palm. It was still there. Still solid. Still impenetrable.

But Lily was on the other side, spinning happily, completely untouched.

Gray’s golden eyes narrowed.

"...Why?"

Cindy was quiet for a moment, her frills lowering as she thought.

"Maybe..." she said slowly, "the barrier doesn’t recognize her as a threat."

Gray turned toward her.

"What do you mean?"

"The Tartarus is a living creature," Cindy said. "It generates this barrier to protect itself from threats. Ships. Mages. Predators. Anything that wants to harm it or take something from it." She paused, her silver eyes meeting his. "But Lily isn’t a threat. She’s not a predator. She’s not a mage. She’s... something else. Something the barrier doesn’t recognize as dangerous."

Gray considered that for a long moment.

"So it only blocks things that want to hurt it."

"Or things it perceives as threats," Cindy corrected. "Lily is neither. She’s just... curious. Playful. Innocent, in her own way."

Gray glanced at Lily, who was now spinning in slow, lazy circles on the other side of the barrier, clearly enjoying herself.

"...She’s also made of darkness and void energy," he said flatly.

"Yes," Cindy admitted. "But she’s not hostile. And maybe that’s what matters."

Gray was quiet for a moment. Then he turned back toward the barrier, his golden eyes narrowing.

"Then how do we get through?"

Cindy drifted closer, studying the shimmering dome.

"Maybe we don’t have to break it. Maybe we just have to convince it we’re not threats."

Gray glanced at her.

"How?"

Cindy was quiet for a moment. Then she raised one small hand and pressed it gently against the barrier. The surface rippled under her touch, but it didn’t push her away. It just... waited.

"I don’t know," she admitted. "But I think we need to try."

Lily, on the other side, spun once more, then darted back through the barrier and hovered in front of Gray. Her five points tilted, her dark core pulsing with curiosity. She nudged his hand with one of her points, as if urging him to follow.

Gray stared at her.

"...You want me to just walk through?"

Lily pulsed once, bright and affirmative.

Gray looked at the barrier.

"...Alright. Let’s see what happens."

He pressed his palm against the barrier and pushed.

The surface resisted for a moment, firm and unyielding. Then, slowly, it began to give way. The barrier rippled around his hand, not breaking, but... accepting. Like water parting around a stone.

Gray’s eyes widened.

"It’s... letting me through?"

Cindy’s frills lifted with hope.

"Keep going!"

Gray pushed further. The barrier continued to yield, rippling around his arm, his shoulder, his chest. It didn’t hurt. It didn’t push back. It just... let him pass.

He stepped through.

The barrier closed behind him with a soft, shimmering pulse, and Gray stood on the other side, his golden eyes wide with disbelief.

"...I’m through."

Cindy stared at him, her silver eyes bright.

"It worked!"

Lily spun happily around Gray, her dark core pulsing with joy.

Cindy pressed her hand against the barrier and pushed. The surface resisted for a moment, then slowly, gently, it parted around her as well. She drifted through, her small axolotl body trembling slightly, and landed beside Gray.

She let out a long, shaky breath.

"We did it."

Gray looked down at his hands, then at the barrier behind them.

"Just like that," he murmured. "We just walked through."

Cindy nodded slowly.

"Maybe the barrier isn’t just a shield," she said. "Maybe it’s a test. To see who’s worthy."

Gray glanced at her.

"Worthy?"

"Of entering the Tartarus’s territory," Cindy said. "Of sharing its space. Maybe it only lets in those who don’t mean harm."

Gray was quiet for a moment, considering that.

"...Then what does it want?"

Cindy looked up at the massive shell above them, its ancient moss and barnacles shimmering in the golden light.

"I don’t know," she said. "But I think we’re about to find out."
