My Ultimate Sign-in System Made Me Invincible Chapter 643 An Anomalous Existence

The next morning, Liam woke up to find himself alone on the bed.

The master suite was quiet, bathed in the soft, golden light of the early California sun filtering through the floor-to-ceiling windows. Lucy and Yanxia had already slipped out, likely to give him the space he needed to prepare for what was coming.

Liam stared up at the ceiling for a long moment. Then he let out a long, slow exhale, clearing the residual comfort of the previous day from his mind. The time for rest was over.

He didn't bother walking to the bathroom. He sat up, lazily raised his right hand, and snapped his fingers.

In a fraction of a millisecond, he was perfectly clean, his hair immaculately styled, and dressed.

He closed his eyes and reached inward, connecting with the interface that had defined his existence for the last eight months.

System, Liam called out, his internal voice steady and absolute. I'm ready. Let's get this over with.

[Acknowledged, Host.]

The next moment, Liam felt reality itself simply contract into a singular, infinitely dense point, before snapping violently inside out.

When his senses recalibrated a millisecond later, he was no longer standing in the Bellemere Mansion. He was no longer standing on a planet, or within a solar system, or even within the conventional bounds of a physical universe.

He was floating—or perhaps standing, the distinction was meaningless here—in an endless, absolute void.

It was a darkness so profound it felt heavy, pressing against his aura like physical water.

For a Loose Immortal, a being whose eyesight could effortlessly pierce the veil of space to see individual asteroids millions of miles away, this was deeply jarring.

There was nothing. No twinkling of distant stars, no cosmic dust, no ambient radiation. Just a suffocating, infinite expanse of absolute zero.

Liam frowned, carefully cycling his Primordial Essence to orient himself, attempting to project his spiritual sense outward.

"That was quite an entrance you made there, Liam."

The voice was sweet, resonant, and carried a melodic tone that seemed to bypass Liam's eardrums entirely, vibrating directly against his soul. It was a voice that commanded the very fabric of existence to listen.

Liam shifted his stance, turning toward the source of the sound.

Suddenly, the absolute darkness parted. A few hundred feet ahead of him sat a throne of staggering, impossible proportions, carved from what looked like fractured pieces of a dying star—a deep, swirling mixture of obsidian and violent purple nebula gas.

Seated upon it was a woman of otherworldly, devastating beauty. She was draped in elegant, flowing garments that seemed to be woven from the void itself. Her eyes were a piercing, luminous violet, carrying the slitted, predatory pupils of an apex dragon.

She was looking down at him, resting her chin on an elegantly manicured hand, her expression one of profound, centuries-deep intrigue.

Liam's mind immediately screamed at him to run.

Because if his Abysall Dragon constitution, every single cell in his body was violently reacting to the presence of its ultimate progenitor. The aura radiating from her wasn't just power; it was absolute, hierarchical supremacy.

She was Tiamat. A Primordial. A being whose peers were the foundational pillars of reality itself.

Liam forced his heart rate to slow, fighting through the crushing, instinctual urge to drop to his knees and press his forehead to the invisible floor. He plastered a small, deliberately mischievous smile on his face to mask his wracking nerves.

"Forgive me, Your Majesty," Liam said, forcing his voice to remain steady. "But just the thought of finally setting my gaze upon your beauty made it rather difficult to think straight."

He inwardly cursed. He hadn't meant to call her Your Majesty. He had wanted to play it cool, to maintain the detached persona that had served him so well. But his vocal cords had essentially hijacked themselves.

The Abyssal Dragon bloodline simply refused to allow him to address her with anything less than absolute, total submission.

Tiamat's violet eyes crinkled in amusement. She let out a low, melodious chuckle that made the void around them vibrate.

"You're trying so hard to hide how nervous you are," she smiled, her voice echoing with ancient amusement. "That is incredibly cute."

Liam internally sighed, abandoning the attempt to play the stoic rogue. He straightened his posture, anchoring himself in the void. "You wanted to see me?"

"Indeed," Tiamat said, shifting slightly on her massive throne. "I have wanted to meet you for quite some time. I was genuinely surprised when the System Administrator informed me that it had finally secured the perfect host. I had my doubts, naturally. But now that I am looking at you..."

She leaned forward, her slitted pupils dilating slightly as she examined him. It felt like she was reading his DNA, his soul, and his entire timeline simultaneously.

"...you truly are the perfect host," she murmured. "How utterly intriguing. Not only were you chosen by the artifact, but you are also a singularity. One of a kind. The only 'you' in the infinite expanse of the multiverse. How did you even manage to survive?"

Liam blinked, his mind instantly snagging on her words. He remembered a conversation he had with the System months ago, back when he first arrived in Mana Universe's parallel Earth. He had asked if there were parallel versions of himself running around out there. The System had bluntly told him no.

At the time, Liam had assumed it was because the System had erased them to ensure his uniqueness, or perhaps it was just a statistical quirk of his specific reality.

But hearing a Primordial confirm it—and refer to it with such profound shock—shifted the context entirely.

"Is that really so rare?" Liam asked, his curiosity momentarily overriding hiw awe. "I'm sure being unique doesn't make me all that different from the countless trillions of souls existing across the Dark Energy, Mana, and Cultivation universes."

"That is exactly where you are wrong, little dragon," Tiamat said, her tone taking on the patient cadence of a teacher explaining gravity to a child. "It is not merely 'rare.' It is a cosmic anomaly. A violation of the natural order."

She gestured gracefully with one hand, and the void between them briefly illuminated with the faint, golden outlines of branching timelines.

"When a soul exists across millions of parallel dimensions, its total weight is divided," Tiamat explained. "It is diluted. Safe. But you? You exist only here. In one single point. One hundred percent of your soul's conceptual weight is concentrated in a single, terrestrial body. The sheer, gravitational density of your existence is what allows you to harbor the System, to progress so impossibly fast without your soul shattering."

She let the golden timelines fade back into darkness.

"Do you know what is required to reach the absolute apex of power? To become a True God, or perhaps even step into the Primordial realm?" she asked softly. "You must consume or merge with your alternate selves. You must make yourself singular. The universe hates singularities, Liam. It actively tries to crush them."

Liam absorbed the information, a cold realization settling in his stomach.

"If you had been born in the Mana Universe, or a Cultivation Universe," Tiamat continued, "the heavenly laws would have sensed your anomalous weight and struck you down with a tribulation lightning bolt the very second you drew your first breath. But you were born in the Dark Energy Universe. A 'godless' realm. That blind spot is the only reason you lived long enough for the System to find you."

Liam stood in silence, recalculating his entire understanding of his own existence. He wasn't just a lucky kid who got a cheat code. He was a cosmic glitch that had hidden in the universe's neglected basement until he was strong enough to punch his way out.

"Fascinating as that is, Your Majesty," Liam said, politely steering the conversation back to the present, "I doubt you summoned me across dimensional boundaries just to give me a lecture on multiversal soul mechanics. What is it you actually want?"

Tiamat smiled, clearly pleased by his directness. "I am getting there. Do not be in such a rush; you have an eternity ahead of you."

She leaned back against the obsidian stone of her throne, her expression turning slightly more solemn.

"You have already been informed of the imminent heat-death of your universe, and the cascading collapse of the entire Cosmos that will follow," she said. "It is all true. The law gears are broken. The foundation is rotting."

Tiamat rested her hands on her lap. "I do not want my children to die. And that now includes you. That is why, when the first of the Void Beasts came to me seeking aid, I chose to intervene. I guided the artifact. I facilitated your path."

She locked her violet eyes onto his. The weight of her gaze pinned him in place.

"You possess the potential to forge new law gears. You can fix the broken machinery of reality," Tiamat said, her voice dropping into a deadly serious register. "But to do so, you will need to leverage the resources of all three universes. You will eventually learn why your universe was abandoned to rot while the others flourished."

She tilted her head. "My question to you is simple, Liam Scott. Once you achieve the power to save your home... do you intend to wage a war of vengeance against the other universes for what they did?"

Liam looked at the Primordial. He thought about the unfathomable scale of the Cultivation Universe, the Mana Universe, and the terrestrial fragility of his own Earth.

He thought about the governments he had just finished checkmating, and the global markets he was currently restructuring.

He let out a short, genuine laugh.

"War?" Liam said, shaking his head. "No. Absolutely not."

Tiamat raised an eyebrow. "You feel no wrath for the injustice done to your home?"

"Wrath is expensive, Your Majesty," Liam said, his detached persona seamlessly bleeding back into his voice, overriding the dragon's instinct to submit. "A multiversal war would be a logistical nightmare, incredibly stressful, and entirely counterproductive. Why would I burn down two perfectly functioning universes?"

Liam smiled, and the expression was sharp, calculating, and ruthlessly pragmatic. "Why kill them, when I can simply monopolize their resources, integrate their economies into LucidNet, and milk them for every single ounce of wealth and power they possess for the rest of eternity?"

Tiamat stared at him for three long seconds. The silence in the void was absolute.

Then, the Primordial threw her head back and laughed. It was a joyous, booming sound that shook the very foundations of the space around them.

"Oh, the System Administrator chose perfectly," Tiamat smiled, her slitted eyes gleaming with profound, delighted approval. "Already thinking exactly like a dragon, I see."
