Reborn In A Perverse Monster World! My System Adapts To Everything!

Chapter 134: A New World? [FIXED!][07/07!]

Jason was quite arrogant with his newfound power.

He could give less of a fuck to be honest. Months of fighting, crawling through dungeons, and facing horrors had left him utterly unscathed. Not a scratch. Not a bruise. Not even a moment of genuine fear. His body had become a fortress, his mind an unbreakable shield, and his power—boundless.

But even Jason could tell this was different.

"There is something here..." Jason muttered under his breath, his eyes scanning the dense forest around him. The corpses. The silence. The absence of life. It all pointed to something far older and far more dangerous than anything he had encountered before.

Jason might be arrogant, but he wasn’t careless. He raised his hand, and a tree branch erupted from beneath his feet, lifting him high above the canopy. The aerial view was stunning—the island stretched endlessly in all directions, its coastline jagged and irregular, its interior a labyrinth of twisted trees and shadowy valleys. And there, at the center of it all, he could feel it.

A presence but he still wasn’t sure what it was as it was unlike anything he had experienced.

Jason wasn’t worried about a single thing. He launched himself into the isolated heart of the island with such speed that the air around him cracked like a whip. Trees blurred past him. The ground became a smear of brown and green. In less than a heartbeat, he appeared right in front of a deserted area.

And in that place, there was a beast.

"There you are," Jason said, his voice calm and flat.

The beast did not look like it had any form of intellect. Its body was twisted and malformed, its skin grey and cracked, its eyes hollow and vacant. It moved with the jerky, unnatural motions of a puppet whose strings were being pulled by an unseen hand. It could not speak. It could not reason. It only knew one thing—to attack.

The beast launched a boulder at Jason with surprising strength.

Jason basically just tanked it. The massive rock hit his bare body and shattered into pieces, crumbling to dust at his feet. He didn’t even blink. His skin was unmarked, his expression unchanged.

"Hm..." Jason muttered under his breath, glancing down at the scattered debris.

He looked around, his senses probing the area. This wasn’t a beast. It was simply someone who had been here long enough to lose their mind, if they were still alive that is, their body animated by something dark.

The creature was nothing more than an animated corpse, repeating the same sequence of events over and over again.

Jason didn’t harm it. Even when the beast punched him multiple times, its fists raining down on his chest and face, it didn’t leave a scratch on his body. Jason just ignored it. This was the least of his concern.

He was looking for the entry. There had to be a way to dive deeper, to reach the heart of whatever was calling to him. And then he saw it—a strange portal, shimmering and unstable, its surface rippling like water disturbed by a stone.

Jason had never seen something like this before. It wasn’t a dungeon entrance. It wasn’t a magical barrier. It was something far stranger. He realized, in that moment, that this portal was leading to a different dimension. That would explain why he couldn’t sense any life on this island. The island itself was just a gateway.

Jason took a deep breath before stepping into the portal.

The moment he crossed the threshold, the atmosphere itself was suffocating. The air burned his throat, thick with toxic fumes that would have killed a normal man in seconds. It constantly drained his mana, pulling at his reserves like a leech. There was no way in hell anyone else could survive this environment.

But Jason was not anyone else.

Thanks to his system and the Marrow, his mana supply was endless. It couldn’t be depleted regardless of what tried to take it from him. The drain was noticeable—he could feel it tugging at his core—but it was like trying to empty an ocean with a thimble.

He took a step. His system immediately began adapting to the toxic atmosphere. Every thirty seconds that passed, his adaptation increased by twenty percent. Within minutes, he could breathe normally. His throat stopped burning. His lungs filled with air that no longer felt like poison.

But the place itself was unlike anything he had ever seen.

There were monsters flying in the sky—massive creatures with leathery wings and razor-sharp beaks, their bodies covered in scales that gleamed like polished obsidian. The ground beneath his feet was covered in strange flora, plants that pulsed with bioluminescence and shifted as if alive. In the distance, he could see massive shapes moving through the mist—creatures that looked like dinosaurs, their footsteps shaking the earth.

It felt like a prehistoric world. A world that had never known the touch of civilization.

"What the fuck?" Jason muttered under his breath. The only thing separating him from those monsters was the portal behind him—a shimmering tear in reality that led back to the island.

Then one of the monsters in the sky saw him.

Its eyes locked onto his figure, and without hesitation, it dove. Its talons extended, its beak opened wide, and it charged right at him with the speed of a falling meteor.

Jason didn’t flinch.

The monster tried to grab him with its talons, but Jason jumped into the air, moving faster than the creature could track. He grabbed its neck, his grip like iron, and with a single, violent motion, he smashed it into the ground.

The impact was devastating. The earth cratered beneath the monster’s body. Its neck snapped with a sickening crack, and its body went limp. Jason landed on its corpse, his boots crunching against its shattered scales.

"This is more than a dungeon," Jason muttered under his breath, his eyes fixed on the sky above. "This is another world."

All the other monsters in the sky turned their attention to him. Their eyes gleamed with hunger, with rage, with something that looked almost like recognition. They let out a disgusting shriek that shook the sky, a sound that seemed to vibrate through his very bones.

Jason’s expression did not change. He stood on the corpse of the fallen monster, his fists clenched, his eyes fixed on the approaching horde.

-

Jason stood amidst the carnage, his body covered in blood from head to toe. Thick, dark ichor dripped from his hair, his face, his clothes, pooling at his feet in a crimson lake. The monsters lay dead around him, their bodies broken and twisted, their shrieks silenced forever. Not a single scratch marred his skin. Not a single wound marked his flesh. He was untouched, untouchable, a god among corpses.

He sighed.

They just had to ruin his clothes.

Jason looked down at his tunic, now torn and soaked through with monstrous blood. It was one of those things that couldn’t be helped. He had faced a horde of prehistoric beasts, snapped their necks, crushed their skulls, and torn through them like paper. A ruined shirt was a small price to pay for survival, but still—he had liked that shirt.

He crouched down and pressed his palm against the ground, sending a pulse of energy through the soil. He searched for life, for any sign of something living beyond the monsters he had just slaughtered. The pulse rippled outward, traveling through the earth, through the roots, through the very fabric of this strange world.

What it found was unexpected.

The very ground was alive. Not in the way of plants or roots—it was something deeper, something he couldn’t quite understand.

The earth itself hummed with a consciousness, a vast and ancient awareness that seemed to stretch across the entire world. This would also explain why the flowers were the way they were, pulsing with bioluminescence, reacting to his presence as if they knew he was there. The ground breathed. The soil dreamed.

But there was something else. Something powerful. Jason could feel it in the center of it all, a presence that radiated power unlike anything he had ever encountered. It was waiting for him, watching him, studying him with an intelligence that transcended the beasts he had just slaughtered.

And then, the creature smirked.

Not because it found what was happening amazing. Not because it was impressed by Jason’s display of power. But because Jason was here. Because he had finally arrived. Because the moment it had been waiting for had come at last.

Jason rose to his feet, his eyes fixed on the distant horizon. His fists clenched at his sides.

"Alright," he said, his voice low and steady. "I’m coming."

-

Jason walked through the dense, bioluminescent forest, his footsteps echoing against the alien ground. The air was thick and heavy, pulsing with a rhythm that seemed to match his own heartbeat. He had been walking for what felt like hours, but he knew time moved differently here.

Then he saw it.

A creature stepped out from behind a massive, twisting tree. It was unlike anything Jason had ever encountered—its skin was the color of burnt ash, cracked and glowing with veins of molten fire. Its eyes burned with a cold, strange light, and its form was vaguely humanoid but twisted, wrong, as if it had been shaped by nightmares rather than nature. It looked like something straight out of hell.

"You have come here... Jason," it said, its voice a low, guttural rumble that seemed to vibrate through the very air.

Jason raised an eyebrow. "Ah, you know my name. I guess I have gotten quite famous."

The creature smiled—a slow, deliberate movement that revealed rows of jagged teeth. Then, to Jason’s surprise, it bowed its head slightly, a gesture of respect that seemed almost out of place given its terrifying appearance.

Jason tilted his head, his expression shifting from amusement to confusion. "What’s this? No attack? No attempt to kill me?"

The creature straightened, its burning eyes fixed on Jason’s face. "I am not here to fight you, Jason. Someone has been expecting you. They have waited a long time for your arrival."

Jason sighed. He had been prepared for a fight, for another bloody confrontation. But if he didn’t need to fight his way through everything, then he wouldn’t. He cracked his neck, a faint smirk playing on his lips.

"Well, lead the way then," he said. "Let’s not keep them waiting."
