Here's the English translation of your scene, with emotional weight and narrative flow preserved:
The mound of gold surrounding the stone pedestal suddenly began to roil, as if an invisible fire were burning it from within. A deep, guttural roar echoed out, mingling with the screech of clashing metal, shattering the atmosphere into fragments.
Out of the chaos, a massive arm covered in golden scales slammed down, swatting Tarek aside like a ragdoll.
His legs went numb, frozen like stone before the terrifying sight.
Tarek was flung from the pile of gold. He hit the floor hard, tumbling across the ground.
The impact left him dazed, barely able to stay upright.
"Copper... Eylis... You traitors...!" Tarek roared, his voice hoarse with fury and pain. His trembling hands clawed at the cracked tiles as he struggled to rise amidst the deafening roar.
His scream seemed to draw every gaze in the room.
But before he could react, a shadow flashed by like the wind. Eylis, moving faster than she ever had, appeared right in front of him.
"I'm sorry, Tarek," Eylis whispered, her voice cold as ice.
Her hand shot out like lightning, yanking the necklace from his grasp. Tarek's eyes widened as his outstretched hands caught nothing but air.
Eylis turned away, her eyes now locked coldly on Copper, who stood near the treasure chamber door, just as it began to close.
That enigmatic smile on Copper's lips was a silent reminder that everything was going according to plan.
His eyes gleamed as though he were savoring a performance he himself had masterfully orchestrated. That chilling smile lingered, a constant reminder that everything was under his control.
Eylis passed Ren, just a flicker of shadow in his vision.
She stood by the door now, but this time, her gaze held more than curiosity. "Thank you, Ren," she said softly, her voice gentle, yet tinged with triumph.
"You were useful after all..." Her words pierced his mind like a dagger.
Eylis's slender hand touched Ren's shoulder, but it was cold, monstrously cold. Not like a human's. The chill from her fingers seeped into him like a curse, making Ren's heart nearly stop.
His breath grew heavy. The world spun around him, and Ren began to fall.
Clinging to the last thread of consciousness, Ren's eyes fixed on the door, now just a narrow slit wide enough for one person to slip through.
Eylis was the one who had thrown him back.
"Good luck," Eylis sneered. Her laugh sliced through the air like a blade.
Her eyes held nothing but scorn, devoid of guilt or sympathy.
Before Ren could react, she darted through the door, her figure fading, leaving him alone in the dark, surrounded by despair.
Ren stood there, gasping. In that moment, he realized he was nothing more than a disposable pawn. The closing door felt like the sealing of fate itself.
It was as if the world around him were collapsing. The air grew heavy, suffocating, like he was sinking into an abyss.
His eyes couldn't leave the shut door where Eylis had vanished like a ghost.
To her, he had been nothing more than a one-use tool. All that remained was darkness, and a deep, burning fear that he might never escape.
"You bastards! What the hell did you do!?" Tarek's men charged forward like wild beasts, their eyes bloodshot, snarling with rage.
But Copper moved with the slightest motion, gliding through them like a phantom, evading every strike with ease.
Every blade missed, tearing only through air, slicing the wind without ever touching him.
Copper didn't strike back, at least not yet. Instead, he rested his hand on the hilt of his sword, which shimmered as though drawing in all surrounding light.
That brilliance burst into glittering fragments as he surged forward, moving faster than the eye could follow, like an arrow released from a bow, leaving behind only faint streaks of light.
And rather than retaliating against his attackers, Copper charged straight toward the Scholar.
The Scholar held a unique crystal, one that glowed more brilliantly than any gem Ren had ever seen.
Its light didn't just illuminate the room; it seemed to carry an invisible force, as though each ray could crush anything in its path.
"Don't touch that!" the Scholar gasped, his voice trembling with panic, his eyes full of unmistakable desperation as he stared at Copper.
The blade flashed through the air, too fast for the naked eye. In the blink of an eye, the Scholar's wrist was severed, and the crystal slipped from his grasp. No blood spilled, only a cascade of red pixels exploded like a digital storm, falling like shards of a broken world.
With inhuman reflexes, Copper snatched the crystal before it hit the ground, without a moment's hesitation.
"No... No, no, no! Give it back! Give it back to me!" the Scholar screamed, eyes wild with loss. His previous calm and confidence were gone, replaced by pure desperation. Every word trembled, as if afraid Copper wouldn't listen.
"We had a deal... I helped you get the Amulet..." the Scholar cried, his voice shaking, trying to clarify, as if fearful Copper had forgotten.
Copper didn't respond right away. He merely took two long steps back, that faint, cold smile still on his lips.
"The fewer who know about this... the better," he said, voice calm, as if nothing mattered more than those words.
Then, with a swift motion, Copper crushed the crystal in his hand. A blinding green light exploded outward, wrapping around his body like a whirlwind of energy.
Ren stood frozen. A familiar dread washed over him. That light... it was the effect of teleportation. A sudden, brutal shift, utterly inescapable. It marked the end of hope... and the beginning of the end.
"Thank you for your help, Tarek. You were truly a wonderful friend." Copper's voice echoed, distant as a fading whisper, as his figure dissolved into the cold green light.
The Scholar's desperate attacks slashed through nothing, slicing into light itself, but never reaching Copper. The world seemed to freeze, leaving only the blurred outline of the betrayer, vanishing into solitude.
"I'm sorry, Scholar. But everyone pays for their greed." Copper's final words rang in Scholar's mind, cold and sharp, an undeniable betrayal.
"Bastard...!" the Scholar screamed, his voice cracking from the depths of despair. The world around him shattered, rage and agony boiling within him.
A heavy silence fell, thick, suffocating, each breath drawing in dread.
But it didn't last long...
The gold around the pedestal didn't just boil, it tore apart, with glittering shards scattering like the remnants of a crumbling world.
A monstrous roar mingled with the shriek of metal, breaking the air into pieces...
"W-What... what is that...?"
A colossal shadow suddenly burst through the floor like a nightmare awakened.
It shot upward with terrifying force, soaring into the air before crashing down with enough impact to crush everything beneath it.
The shockwave from the monstrous landing rippled outward, sending the entire group stumbling back in panic.
The ground trembled as debris and dust surged skyward, the space around them collapsing, while the shadow still stood, ready to unleash devastation.
Ren fought to suppress the surge of fear rising inside him, forcing it into the depths where it couldn't escape. His hands clutched the spear so tightly his knuckles turned white, fully aware that if fear took over, death would not be a distant threat, it would be inevitable.
He took a deep breath, his gaze shifting to the Scholar. A flicker of surprise crossed the man's face...but it was quickly replaced by cold, calculating calm.
The Scholar was no longer desperate. He gripped his spear with one hand, raising it as if declaring war on the monstrous creature before them.
"I understand how to fight this boss now," the Scholar said, voice deep and steady, filled with resolve.
Ren nodded, trying to steady his mind against the aftershocks. "There's no room for failure," he said, trying to hide the anxiety in his voice. "If we want to survive, we have to stand and fight."
The Scholar met his gaze, eyes sharp as steel. "I'll lead the formation. You, don't let fear take over. Right now, fighting is our only way out."
Tarek and his men quickly moved into position.
The first thing to greet them... was the monstrous roar of the beast.
It charged straight at them....
