Infinity: Kill your way through the movie world.

Dean knelt on one knee, pressing his left hand against the wound on his shoulder, and looked at Sam's waist, where the last demonic weapon, the inscribed dagger given to him by Lor, remained, though it had just been knocked away.
He looked ten meters away.

The dagger was still stuck in the ground, its hilt trembling slightly, as if in response to something.

Castio saw it too.

It turned and walked toward the dagger, its steps unhurried, like a confident hunter heading toward its prey in a trap.

“An interesting toy.” It bent down and reached for the dagger. “The runes on it… are ancient, not from this era. I’ll study them carefully.”

Before he could finish speaking, Dean moved.

Instead of rushing towards Castio, he rushed towards Sam, crouching down beside him and drawing the spare demon blade from the man's waist.

Then he turned around and hurled the Demon Blade with all his might.

It wasn't thrown at Castio, but at the engraved dagger.

The demon blade spun in the air, its tip striking precisely the end of the dagger's hilt stuck in the ground.

Ding--
The force of the impact caused the dagger to bounce off the ground and fly into the air.

“Sam!” Dean roared.

Sam struggled to lift his head, his eyes bloodshot, but a dark red light shone deep in his pupils as demonic power was forcibly activated.

He stretched out his still-movable right hand, fingers spread, and activated his telekinesis.

It's not about controlling a dagger, it's about controlling the air.

Centered on the dagger, the air within a three-meter radius was instantly compressed to a solid density. The dagger hovered in the air, like an insect trapped in amber, but it was still trembling slightly.

Castio paused for a moment.

It did not anticipate this type of attack.

In that split second of hesitation, Dean had already rushed to the dagger. He leaped up and kicked the hilt of the dagger with all his might.

The dagger shot towards Castio like a bullet.

This time it couldn't completely dodge.

Pale yellow tentacles reached out from behind, attempting to intercept, but the runes on the dagger suddenly burst forth with a blinding light. Wherever the light passed, the tentacles melted and evaporated as if they were wax in the presence of flames.

The dagger pierced Castio's left calf.

It only penetrated three centimeters before being trapped by muscles and suddenly hardened bones.

But enough.

The runes have been activated.

An eerie light burst from the blade, spreading like a virus along the wound. Castio let out a scream, a higher-frequency, inhuman roar.

It looked down at its calves, watching the light spread beneath its skin. Wherever it passed, the pale yellow lines quickly faded and died, as if encountering a natural enemy.

"No..." it roared, reaching for the dagger.

But Dean won't give it a chance.

He landed, rolled, picked up the broken fragment of the Demon Hunter's knife from the ground, and hurled it with all his might at Castio's face. The fragment hit him, but it wasn't fatal; it only left a bloody gash on his forehead, but it successfully disrupted his movements.

Castio quickly retreated.

It glanced at Dean, then at Sam, and for the first time, a calculating look appeared in its eyes. After quickly assessing the risks, its instincts told it: this body is already damaged, and continuing to fight is not worthwhile.

It made a decision.

escape!
He immediately crashed into the side wall of the warehouse. His body liquefied the moment he touched the wall, turning into a pool of pale yellow viscous liquid that seeped out from the cracks in the brickwork.

The wall bears a human-shaped corrosion mark, with bubbles still bubbling at the edges.

Dean rushed to the wall, but the slime had already spread and blocked the leak.

The two turned and ran towards the warehouse door, rushing out.

Outside is wilderness.

Under the moonlight, a pale yellow trail stretched across the ground, pointing north, where the outline of an artificial lake could be seen. It was an irrigation reservoir built decades ago, now abandoned, but still containing water.

The tracks moved extremely fast, like snakes slithering across the sand.

Dean turned around and called out, "Sam, can we go after him?"

Sam walked out, leaning against the wall, his face pale, but he nodded: "I can... but I can't hold on for long."

"That's enough." The two followed the trail.

Dean ran ahead, with Sam following behind, using telekinesis to reduce the strain on his legs. Blood dripped continuously from the corner of Sam's mouth, but he didn't stop.

The trail extends all the way to the edge of the reservoir.

This is a very large reservoir, more than 500 meters in diameter. The water surface gleams black under the moonlight. It is surrounded by weeds and abandoned pump houses, and the air is filled with the fishy smell of rotting algae.

The trail ended at the edge of the reservoir.

Dean stopped, panting, and looked around.

Castio was nowhere to be seen.

Only a ripple spread out from the center of the water, as if something had just jumped in.

“He went into the water,” Sam said, panting as he leaned against a withered tree. “Leviathans… need water to reproduce. It’s written in the Bible that Leviathans are giant sea monsters.”

Before he could finish speaking, the water exploded.

Something surged up from the bottom of the water, splashing five meters high, like a brief rain in the moonlight. A figure floated in the middle of the water amidst the rain.

Castillo.

But it's different now.

His body was swelling, growing larger like an inflating balloon, his skin stretched until it became transparent, revealing the pale yellow liquid flowing beneath.

The clothes were torn, and fragments floated on the water.

The face was still Castio's face, but it was distorted and deformed, the eyes had turned completely yellow, and the corners of the mouth were stretched to the ears, revealing fine, needle-like teeth inside.

He opened his mouth and emitted a low-frequency vibration that caused dense ripples to spread across the water's surface.

"A carrier..." the voice murmured, mingled with the sounds of water and bursting bubbles, "is needed... a better carrier..."

Then he began to disintegrate.

The body slowly and consciously split apart, the skin splitting open from the chest like a zipper being pulled open, revealing an empty cavity without internal organs. The internal organs had long been eaten by the Leviathan larva, and in its place was a yellow substance that filled the cavity and kept wriggling.

The substance gushed out and flowed into the water.

Castio's body, like an empty raft, collapsed and floated on the water, swaying with the waves.

The face remained in its final form, its eyes open, gazing at the sky, where the yellow had finally vanished, leaving only an empty, lifeless blue.

The yellow substance that gushed out sank to the bottom of the water.

disappear.

The reservoir has returned to calm.

Only Castio's skin floated in the middle of the water, like an abandoned doll.

Dean stood motionless on the shore.

The dagger in his hand was still glowing, but the target had vanished.

Sam walked over to him and silently looked at the water.

After a long time, Dean said, "He's dead."

“The skin is dead,” Sam corrected. “Leviathan is alive, in the water, reproducing.”

Dean looked down at the dagger in his hand.

The runes on the blade are slowly fading, as if it has completed part of its mission, but not completely.

“Lorre…” he said softly, “did he know this would happen?”

Sam did not answer.

He doesn't know the answer.

At the same time, deep within hell, in the crevices of purgatory.

There is no sky, no ground, only endless, swirling dark red mist.

Countless fragments floated in the mist: broken weapons, shattered armor, and half-melted, unrecognizable skeletons.

The air was thick with sulfur and a more ancient, rotten smell, like deep-sea silt. (End of Chapter)
