The thermal conductivity calculation was complete in a fraction of a millisecond. Shin visualized the heat loss as a cascading series of red vectors bleeding away from their bodies into the hungry, entropic maw of the mountain air.

Shin didn't just understand the formula; he was the formula. He adjusted the "k" value—the thermal conductivity—of the air molecules in a thin, shimmering shell around them. By slowing the kinetic transfer of energy, he turned the freezing mountain gale into a tepid breeze.
"How are you doing this?" the real Sung Byeon chattered, his teeth clicking like a broken telegraph. "The snow... it's not melting on your skin. It's bouncing off like it hit a glass wall."
"I am simply refusing to acknowledge the temperature the System is trying to impose," Shin replied. He looked back at Oakhaven. From this height, the city looked like a circuit board being eaten by acid. Entire districts were flickering into white cubes, then vanishing into the "Null" void. "The System is aggressive. It's not just formatting; it's hunting for the specific memory address where my soul is located."
1. The Glitch Stalkers
As they reached the 4,000-meter mark, the "Dead Zone" lived up to its name. The textures of the rocks became repetitive—the same grey crag tiled over and over again. The physics engine here was primitive. Gravity flickered between 9.8\text{ m/s}^2 and 4.0\text{ m/s}^2 every few steps, making Sung Byeon stumble as if he were walking on a trampoline.
Suddenly, the "Echoes" appeared.
These weren't the graceful Administrators from before. These were Glitch Stalkers—amalgamations of discarded assets. One had the head of a library gargoyle and the body of a city guard, its limbs stretching and snapping in "rubber-band" glitches that defied biological limits.
"Intruder... File Not Found," the lead Stalker shrieked. Its voice was a distorted audio loop that caused the surrounding snow to vibrate in geometric patterns.
The Stalker lunged. It didn't move through space; it "clipped" through it, skipping frames of reality to appear instantly in front of Shin. Its arm elongated into a jagged spike of unrendered metal.
2. The Tectonic Shielding: Applied Geology
Shin didn't flinch. He didn't even raise his hand. He focused on the ground beneath the Stalker's feet.
"In a world without updates, the collision physics are weak," Shin whispered.
He accessed the Tectonic Data of the mountain. He didn't use magic to move the earth; he manipulated the Shear Modulus of the rock. By momentarily reducing the rigidity of the granite to that of water, he allowed the Stalker to sink halfway into the mountain. Then, with a sharp mental command, he spiked the density of the rock to that of a diamond.
The Stalker was fused instantly into the mountain, its "Glitch" form unable to overwrite the sudden, absolute physical reality of the granite. It remained there—a half-rendered statue of terror.
"Physics is the ultimate cage," Shin noted, stepping over the frozen anomaly.
3. The Planetary Fight: Red Giant Dimension
The remaining four Stalkers learned. They didn't approach on foot. They began to manipulate the local "Scene Data," trying to trap Shin in a pocket dimension where his laws didn't apply. The sky above the mountain pass tore open, revealing a void of swirling binary.
Shin felt the pull. The System was trying to "Archive" him.
"You want to change the setting?" Shin's eyes flared with a violet light that outshone the dying world below. "Then let's pick a venue with high-energy output."
Shin grabbed the "original" Sung Byeon and the lead Stalker. He didn't warp; he used the Perihelion Coordinates he had memorized in the Ghost Library. He folded the space-time manifold by treating reality like a piece of paper, bringing the mountain pass and a distant star into the same XYZ coordinate.
In a heartbeat, they were gone.
They stood on a scorched, red-rock plateau. Above them, a Red Giant sun occupied half the sky, a bloated, crimson god of fusion. The heat was a staggering 100°C and rising every second. The atmosphere was a caustic soup of carbon dioxide.
The Stalkers screamed—a psychic sound since there was no air to carry the waves. Their dark-energy forms, designed for the "Cool" and "Stable" environment of Oakhaven, began to undergo Thermal Dissociation. Their molecular bonds were literally being shaken apart by the solar radiation.
"In this dimension, Earth is already dead," Shin's voice echoed through their minds, clear as a bell. "Your dark energy is a low-entropy construct. It cannot survive the Inverse Square Law of a dying star's radiation."
The Stalkers tried to launch a combined "Dark Matter" blast—a sphere of pure negation. But in the presence of such overwhelming solar mass, the gravity of the star pulled the blast apart before it could even form.
4. The Finish: Singular Point
Shin stood in the center of the solar fire, his cooling field humming. He held out his hand.
"I am tired of being a guest in this story," he declared.
He didn't just use gravity. He used Applied Quantum Mechanics. He began to compress the air molecules remaining in the Stalkers' localized space. He wasn't just squeezing them; he was forcing them into a state of Degenerate Matter, the kind found in the hearts of dead stars.
He created a Point of Singularity.
It was a tiny, black bead of infinite density. The gravitational pull was so immense that the light from the Red Giant began to bend toward his palm. The Stalkers were stretched—a process called Spaghettification—as their data was sucked into the event horizon of the singularity.
With a final flick of his wrist, he sent the singularity spiraling into the sun's corona. The Stalkers were erased, their "Unsafe" code neutralized by the fusion of a star.
5. The Return: The Source Code Revealed
Back in the library—or what was left of it—the silence was deafening. The "real" Sung Byeon was curled in a ball, his mind unable to process the journey across the stars.
The librarian—the only NPC left in the sector—stood trembling. She held out a library card. It wasn't the one Shin had used before. It was gold, with a pulsing light at its center.
"Your... your Access Key, sir," she whispered.
Shin took the card. As his fingers touched it, the "Source Code" of the entire world flooded his mind. He didn't see magic; he saw Constraints.
The world of Oakhaven was a "Sandbox" created for a being known as The User. The "original" Sung Byeon was a placeholder—a "Useless" character meant to be discarded to drive the plot forward. Shin was the "Error Correction"—a soul imported from a high-physics reality to stabilize the simulation.
"I am the Patch," Shin whispered, his navy-blue eyes turning a deep, permanent violet. "And you," he looked at the shivering boy on the floor, "are the Bug."
The boy looked up, terror in his eyes. "What are you going to do to me?"
Shin adjusted his collar and looked at the golden library card. "The System wants me to delete you to fix the memory leak. But I don't follow the System's logic. I follow the laws of the universe."
He reached out and tapped the air. A holographic interface appeared—the "Source Code" of Sung Byeon's soul.
"I'm going to rewrite your 'Useless' tag," Shin said. "If the Author wants a hero, I'll give them a hero they can't control. I'm going to bridge our souls. Two versions of the same man—one with the heart of this world, and one with the mind of the stars."
6. The New Equation
The sky above the Ghost Library stopped pixelating. The white "Null" void began to fill with new, complex data—equations of motion, fluid dynamics, and quantum uncertainty. Shin was no longer just a transmigrator; he was the Architect.
"The 'Mirror in the Library' is broken," Shin said, walking toward the exit. "But the reflection is just beginning."
As they stepped out into the light of a restructured world, the title card of the world itself flickered. It no longer said "Useless's POV."
It now read: [POV: THE CONSTANT].
Shin looked at the reader—not the people in the street, but the "Presence" beyond the screen.
"I see you," he whispered. "And I'm coming for the keyboard
