Infinity: Kill your way through the movie world.

The power emanating from Castio surged and rippled like a tide.

Just a moment ago, his eyes were filled with wavering pain, filled with thoughts of the wound on Sam's palm and the disappointment in Dean's eyes. These images were like nails driven into his remaining sanity.

But the next second, something deeper took over the body.

The dark lines beneath the skin suddenly lit up, like an electrified circuit board.

The lines radiated from his chest, climbed up his neck, spread to his cheeks, and formed a fine spiderweb pattern at the corners of his eyes.

His eyes changed from blue to pale gold, and then from pale gold to a murky, inhuman glow that mixed with various colors.

“Enough,” Castio said, his voice flat and devoid of any emotion. “These emotions… are distractions.”

He raised his hand and simply waved it, as if brushing dust off his shoulder.

Then an invisible force exploded, like a shockwave from an explosion, and Dean and Sam were thrown into the air, their bodies slamming against the warehouse wall with a dull thud.

The cement wall was cracked, and dust fell in clumps.

Dean coughed up blood and struggled to his feet.

Sam was in a worse situation. The hallucination attack had already exhausted his mind, and now the impact made his vision go black and his ears ring.

Castio didn't look at them, but the influence of Castio's will made him hold back and not kill the two brothers.

He turned and walked deeper into the warehouse, toward the ruins of the Gate of Purgatory, which had been opened by Crowley and was now nothing but a charred pit.

Moonlight streamed through the hole in the roof, illuminating the pale yellow crystals along the edge of the pit—remnants of purgatory energy, like dried pus.

He stopped at the edge of the pit and looked down at the crystals.

Then raise both hands, palms down.

The crystals began to glow.

The faint light, like fireflies, but numbering in the thousands, emerged from the bottom of the pit, from the cracks in the walls, and from the dust floating in the air.

All the points of light converged toward Castio, like iron filings being attracted by a magnet.

He is absorbing residual energy.

“No…stop, Cass.” Dean rasped, bracing himself against the wall to stand up. A sharp pain shot through his ribs; one or two might be broken. But he didn’t stop, continuing to stagger forward. “Sam, do it!”

Sam bit his tongue, forcing himself to stay awake through the pain. He pulled out the parchment from his pocket; it was the forbidden spell given to him by Crowley, already activated with blood and ready to be activated.

The two simultaneously unfolded the parchment and pressed their bloodied fingers against the center of the rune.

This time there were no chains.

Two dark purple beams of light shot out from the parchment, intertwining in the air to form a net that enveloped Castio.

The net wasn't moving fast, but Castio didn't dodge. His attention was completely focused on absorbing energy, and his body was on guard.

The net covered him and tightened instantly.

Castio's body stiffened, and the absorption process was interrupted.

The pale yellow specks of light lost their guidance and drifted aimlessly in the air. He looked down at the energy net wrapped around his body, and confusion returned to his face.

"You..." he began, his voice returning to its original tone, but very weak, "Why are you stopping me... I need power, I need to purify this world..."

"That's not purification, that's destruction." Dean and Sam approached from the left and right, the parchment in their hands growing brighter and brighter. "Casdio, wake up! Look at yourself! Look at what you've become!"

Castio lowered his head.

He saw the wriggling lines on his hands, the pale yellow mucus seeping from under his fingernails, and something vaguely swimming under his skin, like countless tiny fish swimming beneath his skin.

His pupils contracted instantly. "No..." he whispered, "This isn't...this isn't me..."

At that moment, Dean gave Sam a look.

The two quickly summoned the Death Knight.

The temperature inside the warehouse plummeted.

The water vapor in the air instantly condensed into ice crystals, which floated and reflected the moonlight, like a still snowfall.

Frost flowers formed on the ground, spreading, climbing the walls, climbing the pillars, and climbing Castio's body, which was entangled in the net.

The Death Knight emerged from the frost flowers.

He was still wearing that worn-out black suit, and his bone cane tapped the ground with a regular clicking sound.

He walked up to Castio, looked up, and although Castio was entangled in the net, he was still a head taller than the old man.

“Castio Miller,” the Death Knight spoke, his voice like sandpaper rubbing against a tombstone, “or should I call you… the first host of Leviathan?”

Castio stared at him: "Who are you?"

“The one who manages the end,” the Death Knight said, “and what you are creating now is a massive chaos and death that should never have happened.”

He raised his cane, the tip of which touched Castio's chest.

There was no skin contact, just a half-inch distance between them.

But where the tip of the staff pointed, Castio's clothes began to rot, aging rapidly as if they had aged for hundreds of years, becoming brittle and turning to ashes.

The skin beneath the clothes was exposed, with no wounds, only dense, pale yellow, tiny bumps that resembled fish eggs.

Each bump was pulsating slightly.

“What you absorbed was not an ordinary soul.” The Death Knight’s staff moved, tracing along the protrusions. “It was a creation sealed by God himself—Leviathan. It is not a living being, but a concept, the embodiment of greed, a devouring entity with the instinct for infinite expansion.”

He retracted his cane and made a vague gesture in the air.

The air rippled like water, and an image appeared at the center of the ripple.
The first scene takes place inside Castio's blood vessels, where numerous pale yellow microorganisms swim like tadpoles, devouring blood cells, immune cells, and anything else they can.

Each time it devours some, it splits again, its numbers increasing exponentially. A thin membrane has covered the blood vessel wall, beneath which lies a surging yellow ocean.

The second act is about Castio's internal organs.

The surface of the heart is covered with yellow lines, like roots taking root, and one-third of the alveoli in the lungs are filled with yellow material.

The liver turned dark yellow, like a huge piece of amber, and all the organs were being slowly and thoroughly transformed.

The third act takes place at some point in the future.

Castio stood in the center of the city, his body swelled to three times its original size, his skin transparent, revealing the surging yellow ocean within.

Then, like a water balloon bursting, pale yellow mucus and countless larvae sprayed into the sky, covering an area with a radius of one kilometer.

After the mucus lands, the larvae burrow into the soil, into sewers, and into the bodies of animals and humans.

The final scene takes place three days after the third scene.

On a city street, pedestrians suddenly froze, their eyes turned pale yellow, and lines appeared under their skin.

They began attacking those around them, sticking their fingers into the eyes, mouths, and ears, and pouring yellow mucus into them.

Infected individuals can transform within minutes and join the attack, turning the city into hell within seventy-two hours.

The image disappeared. (End of Chapter)
