The air crackled with tension as Zen and Arthur faced each other on the training grounds. The lush grass beneath their feet bent under the weight of their stances, each brother poised for combat. Tess, Carac, and Elvis watched from the sidelines, their eyes wide with anticipation.
Arthur's blade whistled through the air, a silver arc aimed at Zen's midsection. Drawing upon the strange energy surging through him, Zen pivoted at the last second. The greatsword missed him by a hair's breadth, slicing through his tunic but leaving his skin unmarked.
"Not bad, little brother," Arthur grinned, his eyes alight with the thrill of combat. "But let's see how you handle this!"
He launched into a flurry of strikes, each blow carrying the force of a battering ram. Zen found himself hard-pressed to keep up, his newly awakened "Aura Manipulation" working overtime to enhance his reflexes and strength.
Clang! Clang! Clang!
The sound of steel meeting steel rang out across the grounds. Zen parried and dodged, his movements becoming more fluid with each exchange. He could feel the energy within him responding to the challenge, growing stronger as he pushed himself to the limit.
"Come on, Zen!" Arthur taunted, his blade a blur of motion. "Show me what that fancy new skill of yours can really do!"
Gritting his teeth, Zen decided to go on the offensive. He feinted left, then spun right, bringing his sword down in a powerful overhead strike. Arthur's eyes widened in surprise at the sudden aggression, barely managing to bring his blade up in time to block.
The impact sent shockwaves through both brothers' arms. For a moment, they stood locked in a contest of strength, neither willing to give an inch. Zen's arms trembled with the effort, but he held firm, drawing more and more upon the wellspring of energy within him.
"Impressive," Arthur grunted, a bead of sweat rolling down his brow. "But raw power isn't everything!"
With a sudden twist, Arthur broke the deadlock and swept Zen's legs out from under him. Zen hit the ground hard, the breath knocked from his lungs. He rolled desperately to the side as Arthur's blade came crashing down, embedding itself in the earth where Zen's head had been a split second before.
Scrambling to his feet, Zen barely had time to raise his sword before Arthur was upon him again. The older brother's training at the Imperial Academy showed in every movement - each strike precise, each step calculated. Yet Zen refused to back down, meeting Arthur's onslaught with a determination that surprised even himself.
As the duel raged on, Tess watched with a mixture of awe and fear. The vision of Zen's potential death flashed through her mind, causing her to flinch with each near miss. "Be careful!" she wanted to shout, but the words caught in her throat.
Carac observed the fight with a critical eye, noting how Zen's apparent "Aura Manipulation" seemed to grow stronger as the battle progressed. There was something odd about it, something that didn't quite align with what he knew about awakened skills. He filed the observation away for later consideration.
Back in the thick of the fight, Zen found himself being driven back towards the edge of the training grounds. Arthur's relentless assault left him no room to counterattack, forcing him to focus entirely on defense. With each step backward, Zen could feel his back getting closer to the stone wall that marked the boundary of the area.
"What's wrong, Zen?" Arthur called out, a hint of disappointment in his voice. "Is this all your Aura Manipulation can do? Defend?"
Something in Arthur's taunt struck a chord in Zen. He thought of the vision he'd experienced, of the chaos and destruction that awaited the Empire. He thought of Tess's premonition of his death. In that moment, a fierce determination welled up inside him.
"No," Zen growled, his voice low and intense. "This is what it can do!"
With a sudden burst of speed that caught Arthur off guard, Zen ducked under his brother's swing and rolled past him. In one fluid motion, he sprang to his feet and launched a counterattack. His blade moved with a speed and precision he'd never known before, forcing Arthur onto the defensive for the first time in the fight.
"That's more like it!" Arthur laughed, genuine excitement in his voice as he parried Zen's strikes.
For several exhilarating moments, Zen pressed his advantage. His sword became an extension of his will, each strike fueled by the mysterious energy of his "Gluttony" skill masquerading as Aura Manipulation. Arthur found himself giving ground, his expression a mixture of pride and concentration as he fended off Zen's assault.
But even as Zen pushed himself to new heights, he could feel the strain beginning to take its toll. The energy that had surged through him was starting to wane, his movements becoming just a fraction slower with each passing second.
Arthur, with his years of training and superior physical conditioning, noticed the shift immediately. His eyes narrowed, a predatory gleam entering them as he prepared to turn the tables.
In a blindingly fast sequence of moves, Arthur parried Zen's next strike, stepped inside his guard, and brought the pommel of his sword crashing into Zen's solar plexus. The air rushed from Zen's lungs in an explosive gasp. Before he could recover, Arthur's foot swept his legs out from under him once more.
Zen hit the ground hard, his sword clattering away across the grass. In an instant, Arthur's blade was at his throat, signaling the end of the duel.
For a long moment, the only sound was the heavy breathing of the two brothers. Then, Arthur's face broke into a wide grin. He lowered his sword and extended a hand to Zen.
"Not bad at all, little brother," Arthur said, pulling Zen to his feet. "Not bad at all. That Aura Manipulation of yours is something else. With a bit more training, you might even give me a run for my money!"
Zen accepted the help up, his body aching but his spirit soaring. Despite the loss, he felt a sense of accomplishment. He had held his own against Arthur, even if only for a while, and he had gained valuable insight into the workings of his secret "Gluttony" skill.
As Tess and the others rushed over to congratulate them on the spectacular duel, Zen couldn't help but feel a glimmer of hope. If he could improve this much in just one fight, who knew what he might be capable of with more practice? The future might be uncertain, fraught with danger and potential catastrophe, but Zen was more determined than ever to face it head-on.
