My Ultimate Sign-in System Made Me Invincible

The Heart of 18 Magic Circles pulsed steadily in Liam’s reconstructing chest, its eighteen chambers beating in perfect rhythm. Blood vessels spread outward like silver threads, preparing pathways through a body that was still forming. The Dao Bones continued growing, each rib decorated with glowing runes that shifted between deep purple and flowing darkness.

Then space tore open again and the Origin Devouring Body emerged.

It didn’t have a physical form. Instead, it appeared as pure essence—a swirling mass of energy that looked like liquid starlight mixed with absolute darkness. The essence moved with awareness, with intelligence, flowing through the void toward Liam’s skeletal form.

The Voidling’s massive eyes tracked its approach, but was too shocked to say anything. It realised that the force backing this human had access to things that should have been lost to time itself.

The Origin Devouring Body reached Liam’s bones and simply flowed into them.

The effect was immediate and total.

The runes covering his Dao Bones blazed with new light. But these weren’t the same runes that had been there before. New symbols appeared, overlaying the old ones, creating layers of meaning that went deeper than simple magic. These runes pulsed with hunger—a need to consume, to absorb, to devour everything they touched.

The runes spread like wildfire across his skeleton. They covered every surface, every curve, every edge of bone. They flowed along his spine, wrapping around each vertebra in intricate patterns. They climbed up his ribs, decorating them with symbols that seemed to shift and change when looked at directly.

Then his flesh began to form.

It started as wisps of material, barely visible against the void. Thread-thin strands of tissue emerged from the bones, reaching outward, connecting to each other. The strands multiplied, growing thicker, more substantial. Muscle fibers wove themselves into existence, wrapping around the Dao Bones with purpose.

But this wasn’t normal flesh. The tissue that formed carried the same runes as the bones beneath it. They appeared just beneath the surface, glowing faintly through skin that hadn’t fully formed yet. The runes pulsed in rhythm with the Heart of 18 Magic Circles, creating a network of power that flowed through every part of his reforming body.

The flesh continued growing, layer by layer. First came the deep muscle, attached directly to bone. Then the organs began reforming around the magical heart—lungs that expanded and contracted despite the vacuum of space, a stomach and intestines that glowed with inner light, kidneys that pulsed with energy rather than processing waste.

Everything was wrong by normal standards. But everything was perfect by the standards of what Liam was becoming.

His skin formed last, spreading across the muscle like a living blanket. It looked almost normal at first glance—human skin, familiar and unremarkable. But beneath the surface, the runes glowed softly, visible as faint patterns that moved and shifted like shadows beneath water.

The Origin Devouring Body settled into every cell, every fiber, every piece of the new form. It merged so completely that there was no distinction between Liam’s body and the constitution itself. They were one thing now, inseparable.

Liam’s body was nearly complete. Arms, legs, torso—all reformed and decorated with hidden runes. But his head remained mostly unchanged. The skull floated there, empty eye sockets staring at nothing, waiting.

Space tore open one final time and through this last breach came the Dao Array Eyes.

They appeared as twin spheres of concentrated power, floating through the void side by side. Each sphere was roughly the size of a human eye, but there was nothing human about them. And within each sphere, arrays of symbols rotated, creating configurations that hurt to look at directly.

The Dao Array Eyes reached Liam’s empty sockets and simply sank into place.

The moment they settled, his entire body convulsed.

His back arched, every muscle going rigid. The runes covering his bones flared bright enough to be blinding, and the runes beneath his skin pulsed in response. The Heart of 18 Magic Circles accelerated its beating, all eighteen chambers pumping in perfect synchronization.

The eyes began changing immediately.

The colors within them shifted and settled, no longer the chaotic swirl of before. The pupils formed—but they weren’t normal. Instead of solid black circles, Liam’s pupils became something else entirely. They looked like tiny galaxies, filled with swirling colors that moved and shifted. Purple mixed with gold, which bled into blue, which transformed into shades that had no names. The colors constantly changed, flowing through spectrum after spectrum in patterns that seemed random but carried hidden meaning.

Around the pupils, where the white of normal eyes should be, something else emerged. Runes. Hundreds of them, maybe thousands, appearing beneath the surface of the eye itself. They glowed faintly, barely visible unless looked at from certain angles. The symbols rotated slowly, creating arrays that shifted and reconfigured with each passing moment.

The transformation was complete, but the process wasn’t finished.

Liam’s naked body hung motionless in the void, his new form perfect and still. The runes beneath his skin glowed softly, pulsing in rhythm with the Heart of 18 Magic Circles. His eyes remained closed, the swirling colors of his pupils hidden behind pale eyelids.

Then something new began.

It started as a single point of darkness on his back, appearing between his shoulder blades. The darkness spread slowly at first, like ink bleeding through paper. It crawled across his skin in flowing lines, creating shapes and patterns that seemed to draw themselves.

The Voidling’s massive eyes fixed on the forming image, watching with complete attention as the darkness continued its work.

A dragon emerged from the spreading lines.

Not a simple drawing or decorative symbol. This dragon looked alive, even though it existed only as art on Liam’s skin. Its scales were rendered in such perfect detail that each one seemed to catch light differently. Its wings spread across Liam’s shoulder blades, the membrane between the bones so thin it appeared translucent. Its tail coiled down his spine, following the curve of the Abyssal Dragon Spine beneath.

The dragon’s head rested at the base of Liam’s neck, jaw slightly open to reveal teeth that looked sharp enough to tear through reality itself. Its eyes—even rendered in tattoo form—carried an intelligence that made them seem aware. They looked out from Liam’s back with a gaze that held both menace and majesty.

The darkness of the dragon wasn’t uniform. It shifted through different shades—deep black that seemed to absorb light, purple so dark it was almost invisible, hints of blue that appeared and vanished like distant stars. The creature looked like it had crawled up from some endless abyss and claimed Liam’s back as its territory.

The tattoo spread further, flowing down his arms.

On his right hand, lines of energy appeared—three distinct streams spiraling around each other. One stream glowed with soft gold light, another pulsed with deep blue, and the third shifted through colors that had no names. The three energies chased each other, winding together in a pattern that drew the eye and held it.

The streams met at his palm, where they combined into a sphere of power. The ball of energy looked like it contained galaxies within it, swirling with colors that moved and changed. The sphere pulsed with a rhythm that matched the Heart in Liam’s chest.

His left hand received the same marking—three energies spiraling, meeting, combining into that impossible sphere of power.

The tattoo continued its journey across Liam’s torso.

Creatures appeared on his chest, emerging from the spreading darkness like they were swimming up from beneath his skin. Not just one or two, but dozens of different beings, each rendered in perfect detail.

A phoenix spread its wings across his ribs, feathers flowing in colors that shouldn’t exist. A white tiger prowled along his collarbone, muscles defined beneath fur that seemed to move when light hit it from different angles. A serpent coiled around his waist, scales catching nonexistent light in patterns that mesmerized.

More creatures appeared—some familiar like wolves and eagles and bears, others completely alien with too many eyes or limbs that bent in wrong directions. But they were all beautiful. Every creature was drawn with such care, such attention to detail, that they looked more real than living things.

The colors were what made them truly extraordinary. The phoenix’s feathers shifted through reds and oranges and golds that seemed to glow from within. The tiger’s white fur held hints of blue and silver. The serpent’s scales reflected colors that changed depending on which direction you looked from.

The tattoos weren’t just decorative. They carried power. The runes beneath Liam’s skin seemed to recognize the new markings, pulsing in response to their presence.

Everything was connected. Everything was part of a whole.

The Voidling watched as the last lines of the tattoo completed themselves, the final details falling into place. The cosmic administrator had witnessed countless strange phenomenals over its millions of years of existence, but nothing quite like this.

Then Liam’s body ignited, as light exploded from every tattoo simultaneously, so bright the Voidling had to partially close its eyes despite being designed to look directly at stars. The darkness of space was driven back by the brilliance, creating a sphere of radiance around Liam’s floating form.

The dragon on his back tore free, with the tattoo literally pulled away from his skin, becoming three-dimensional, becoming real.

The dragon that emerged was massive—not as large as the Voidling, but huge enough that its wingspan could have covered a city. Its scales were pure black, darker than the void around them, and it radiated an aura of ancient, terrible power.

The dragon’s eyes opened and they fixed on the Voidling for a moment. Then the creature threw back its head and roared. 𝒇𝙧𝙚𝓮𝔀𝓮𝒃𝙣𝓸𝒗𝒆𝒍.𝙘𝒐𝒎

The sound transmitted through the void itself, a cry of freedom and power that made space ripple. The Voidling felt the roar press against its consciousness, acknowledging it as an equal.

This wasn’t some mindless beast. This was something aware, something that understood what it was and where it came from.

The dragon circled around Liam’s unconscious form once, twice, its movements fluid and graceful despite its size. Then it simply existed there, hovering protectively near its source.

The creatures on Liam’s chest followed.

One by one, they pulled free from his skin and became real. The phoenix spread wings of actual flame, burning with a bright crimson colour. The white tiger landed on nothing, its paws finding purchase on empty space as if solid ground existed beneath it. The serpent uncoiled, stretching to impossible length, its body extending far beyond what the tattoo’s size should have allowed.

All the creatures emerged—dozens of different beings, each one radiating its own unique power. They flew and crawled and swam through the void around Liam, creating a living constellation of impossible life. Some were tiny, no larger than birds. Others rivaled the dragon in size, their forms taking up vast stretches of space.

But they didn’t scatter. They stayed close, orbiting around Liam like moons around a planet, like planets around a star. They moved in patterns that seemed random but carried hidden order, weaving between each other without ever colliding.

Above Liam’s head, the energy sphere manifested.

It pulled free from both his hands simultaneously, the two spheres merging as they rose. The combined ball of power was the size of a small building, rotating slowly, containing what looked like entire galaxies within its depths. The three energies that formed it, continued their eternal spiral, chasing each other through the sphere’s interior.

The light grew even brighter, until the Voidling couldn’t look directly at Liam anymore. The dragon roared again, joined by the calls of a hundred different creatures. The energy sphere pulsed with power that made reality itself vibrate.

Then, as suddenly as it began, it stopped.

The light vanished and the sound ceased. The dragon dissolved back into darkness and flowed back onto Liam’s skin, settling into place as if it had never left. The creatures returned, each one shrinking and flattening, becoming tattoo once more. The energy sphere split into two, flowing down to rest on Liam’s palms as beautiful artwork.

Silence returned to the void.

Liam floated there, his body decorated with tattoos that held secrets and power beyond measure.

The Voidling stared at the transformed human with something approaching disbelief. It had witnessed the transformation from beginning to end, had seen every impossible stage, and still struggled to accept what floated before it.

It continued its protective vigil around Liam’s unconscious form. The transformation was truly complete now. What happened next was up to the universe itself.

And to whatever entities had taken notice of this impossible creation floating in their territory. And surely, Liam had attracted the attention of every entity in the Grand Universe, and they were coming for him.
