My Ultimate Sign-in System Made Me Invincible - Chapter 379: The Infinite Dimension

Chapter 379: The Infinite Dimension

Inside the Infinite Dimension, Liam existed in a state that defied description.

The Voidling’s protective field surrounded him like a bubble of reality carved from impossible space, and only through this protection could he maintain any semblance of coherent consciousness.

Without it, he would have been annihilated instantly by the simple incompatibility with a realm that operated on principles his mind couldn’t process.

The space around them was simultaneously darker than the deepest void of interstellar space and impossibly, paradoxically bright. Colors that had no names in any human language flickered across his vision, hues that existed outside the electromagnetic spectrum his eyes were designed to perceive. His enhanced vision, which had allowed him to see clearly in the absolute darkness beyond the Oort Cloud, struggled and failed to make sense of what surrounded them.

Shapes moved at the edges of his perception—or perhaps they were stationary and he was moving through them. Distance had no meaning here. Something that appeared kilometers away would suddenly press against the Voidling’s protective field, then recede to infinite remoteness without having moved at all.

Liam felt his sanity straining against the sensory overload. His mind kept trying to impose order on the chaos, to categorize and understand what he was experiencing, but every attempt resulted in cognitive dissonance so severe it physically hurt. His enhanced brain, capable of processing information far beyond human baseline, was approaching its absolute limits simply by existing in this space.

“You are experiencing the Infinite Dimension,” the Voidling’s telepathic voice cut through the confusion like an anchor to sanity. “No beings from material realities can withstand exposure to this place. That your mind has not already shattered speaks to your remarkable resilience.”

Liam managed a strained response, forcing words through the mental fog. “What… what is this place?”

“Pure nothingness,” the Voidling replied, its massive body swimming through the impossible space with movements that suggested this was its natural habitat. “But also everything. This is where realities that have fallen return to, and where partially formed realities float, waiting to coalesce into something stable or dissolve into entropy.”

The creature’s bioluminescent lights pulsed gently as they traveled, creating the only reference point Liam could cling to. Without those steady blue lights, he would have lost all sense of direction, of self, of existence itself.

“Time does not function here as you understand it,” the Voidling continued, its tone taking on a quality that might have been pedagogical if filtered through something less alien. “The past, present, and future of all realities within the Dark Energy Universe exist simultaneously in this space. What you perceive as causality—one event following another—is an illusion created by material existence. Here, that illusion cannot be maintained.”

Liam tried to process this information but found his thoughts sliding away from comprehension like water off glass. Understanding time’s non-existence wasn’t something his linear consciousness could achieve, no matter how enhanced it had become.

The Voidling seemed to sense his struggle and shifted topics. “The Dark Energy Universe that contains your Earth, your solar system, your galaxy—it is merely one of three universes that orbit the Grand Universe. A lesser realm, the weakest of the three satellite universes, bound by restrictive laws that prevent its inhabitants from achieving power levels common in the other realms.”

“Why?” Liam managed to ask, his voice barely more than a whisper in his mind.

“Stability,” the Voidling replied simply. “Your universe’s laws are restrictive precisely because it is fragile. Without those restrictions, it would have collapsed eons ago. The Grand Universe’s overseers—entities of incomprehensible power—maintain these laws to preserve your reality’s existence.”

They continued swimming through the impossible space, and Liam found himself adapting slightly to the sensory chaos. His mind was learning to filter out the aspects it couldn’t process, focusing on the Voidling’s presence and voice as anchors to sanity.

“Tell me more,” he said, his mental voice growing steadier. “About the Grand Universe. About the connection between our universes.”

“There is much to tell, but little that your current comprehension can grasp,” the Voidling said, though not unkindly. “What you must understand is this: your universe exists under constant threat. Its weakness makes it a target. In the distant past, long before I existed, beings from one of the other satellite universes attempted invasion.”

“My kind was young then. My parents were barely beyond childhood themselves—a few billion years old, still learning their role as cosmic administrators. The invaders came through the Infinite Dimension, believing the Dark Energy Universe’s weakness would make conquest simple.”

Liam felt his pulse quicken despite the otherworldly environment. “What happened?”

“They died,” the Voidling said flatly. “All of them. Not through battle, though there was fighting. Not through our efforts, though we fought desperately. They died because the Dark Energy Universe itself rejected their existence.”

The creature’s eyes seemed to focus on something distant, perhaps accessing inherited memories from its parents.

“Dark energy is not merely a force in your universe—it is the baseline condition of reality itself. The expansion pressure, the entropic framework that holds existence open and prevents total collapse. Beings from other universes are ontologically incompatible with this fundamental nature. When they entered through the Infinite Dimension, reality itself began to erase them.”

Liam’s enhanced mind seized on the technical explanation, grateful for something concrete to analyze. “You’re saying dark energy functions like… like an operating system? And they were incompatible programs trying to run on hardware that couldn’t support them?”

“A crude but functionally accurate analogy,” the Voidling acknowledged. “Their forms, their essence, the very laws that defined their existence—all of it conflicted with the Dark Energy Universe’s fundamental nature. They began destabilizing the moment they entered. Some lasted hours. The strongest managed days. But in the end, entropy claimed them all.”

The creature’s voice took on a heavier quality. “But their dying was not clean or simple. In their desperation, in their struggle against dissolution, they destroyed vast sections of the universe. Realities collapsed. Countless trillions of beings across multiple galaxies died as the fabric of existence tore around the invaders’ thrashing.”

Liam felt a chill that had nothing to do with the temperature of the Infinite Dimension. “You said they were strong. How strong?”

“The weakest among them had achieved what beings in the realms connected to the Grand Universe call the First Divine Rank True God Realm and Great Dao Ancestor Realm. In your universe’s terms…” The Voidling paused, searching for comparison. “There are no terms. Your universe has never produced beings of such power. The restrictive laws prevent it.”

Liam’s smile turned wry. Divine Rank True Gods had sounded like the peak of power when the system had mentioned cultivation realms. Now he learned that even those terrifying entities had been slaughtered not by superior force, but by simple incompatibility with a universe that rejected their existence.
