The training grounds were quiet that afternoon, bathed in warm sunlight that spilled across the stone courtyard and the neatly arranged rows of wooden practice dummies. A gentle breeze stirred the banners hanging from the palace walls, carrying the faint scent of grass and dust. To anyone watching from afar, the scene looked ordinary—just another peaceful day in the royal capital of Ardentia. But for Leon Valerian, everything felt different. Every sound, every movement, every breath he took reminded him that he had returned to a moment in time that should have been lost forever.
Leon stood alone in the center of the training yard, gripping a wooden practice sword tightly in both hands. The weapon felt lighter than the steel blade he had wielded during his final battle, yet his heart beat just as heavily. Across from him stood a worn practice dummy carved from thick oak, its surface scarred by years of training strikes from knights and soldiers. Leon stared at it as if it were an enemy on the battlefield.
Thirty days.
That was the first mission the mysterious system had given him.
Train swordsmanship for thirty consecutive days.
It sounded simple, almost laughably so compared to the chaos of war he remembered from his previous life. But Leon knew better than to underestimate something granted by a power capable of turning back time itself. If the system had given him this mission, then completing it would likely be the first step toward unlocking the strength he would need in the years ahead.
He raised the wooden sword slowly.
The grip felt unfamiliar.
Not because he lacked experience—far from it. In his previous life he had spent years training with the royal knights and fighting on the battlefield. But his current body was that of a twelve-year-old boy. His muscles lacked the strength and endurance he once possessed. His arms felt lighter, less steady.
For a moment, frustration flickered across his face.
But he quickly suppressed it.
Strength could be rebuilt.
Time was now on his side.
Leon exhaled slowly and adjusted his stance.
His left foot slid slightly forward, his knees bending as he lowered his center of gravity. He remembered his father correcting this very posture countless times when he was younger.
"Your stance is the foundation of every strike," King Aldric had once told him. "Without balance, even the sharpest blade becomes useless."
The memory tightened something deep in Leon's chest.
His father was alive.
At this very moment, somewhere inside the palace, the legendary king of Ardentia was likely reviewing military reports or meeting with his generals. In Leon's previous life, he had watched that same man fall beneath a rain of enemy spears.
But not this time.
This time, Leon swore silently, the future would change.
With a sharp breath, he swung the wooden sword.
The strike cut cleanly through the air and slammed into the practice dummy with a dull thud.
Again.
And again.
Leon continued striking, his movements steady and deliberate as he forced his body to remember the rhythm of swordsmanship. Each swing was followed by a quick adjustment of his stance, each movement carefully controlled. Sweat soon began to form along his forehead as the afternoon sun grew hotter, but he ignored the discomfort.
Minutes passed.
Then an hour.
The quiet training yard gradually filled with the repeated sounds of wood striking wood.
Thud.
Thud.
Thud.
Leon's arms began to ache, the muscles in his shoulders burning from the unfamiliar strain. His breathing grew heavier as fatigue slowly crept into his body. In his previous life he could have trained for hours without pause, but now his younger body was already reaching its limits.
Still, he refused to stop.
The image of Marcus Ravenhart standing over him on the burning battlefield flashed through his mind.
That traitor had stolen everything from him.
His family.
His kingdom.
His future.
Leon's grip tightened around the sword.
Thud.
Another strike landed against the dummy.
Pain spread through his wrists, but he ignored it.
Every swing carried a silent promise.
This time would be different.
The future would not repeat itself.
He would grow stronger—strong enough to crush every enemy who dared threaten his kingdom.
As the sun slowly began to descend toward the horizon, Leon finally lowered the practice sword. His chest rose and fell rapidly as he struggled to catch his breath. Sweat soaked through his training clothes, and his arms trembled from exhaustion.
But there was a strange satisfaction in the pain.
For the first time since his rebirth, he felt as though he had truly taken a step forward.
Just then, the familiar cold voice echoed inside his mind.
[Training progress detected.]
Leon blinked.
A faint blue interface appeared before his eyes.
Mission: Train Swordsmanship for 30 consecutive days
Day 1 Progress: Completed
Remaining Days: 29
Leon stared at the glowing text.
So the system really was tracking his progress.
A slow smile appeared on his face.
"Good," he murmured quietly.
If the system rewarded effort, then he would give it everything he had.
Just as he was about to return the practice sword to the rack, a voice suddenly called out from the entrance of the training grounds.
"Leon?"
Leon froze.
That voice…
He turned slowly.
A young girl stood near the gate of the training yard, watching him with curious eyes. She wore a simple white dress, and her long silver-blonde hair shimmered under the afternoon sunlight. Despite her calm expression, there was a playful warmth in her gaze.
For a moment, Leon's heart stopped.
"Elira…?"
The name slipped from his lips before he could stop himself.
His younger sister tilted her head in confusion.
"Yes?" she replied. "Why are you looking at me like that?"
Leon stared at her.
In his previous life, this girl had vanished during the invasion of Ardentia. He had never discovered what truly happened to her—whether she had escaped, been captured, or died somewhere in the chaos.
For years that question had haunted him.
But now she stood before him, perfectly safe.
Alive.
Leon felt an unexpected tightness in his throat.
Elira frowned slightly as she walked closer. "You've been training all afternoon again," she said. "Father will scold you if you push yourself too hard."
Leon quickly turned away, pretending to adjust the sword rack so she would not see the emotion in his eyes.
"I'm fine," he said quietly.
Elira crossed her arms. "You say that every time."
Leon let out a small breath.
Her voice, her expressions, even the way she complained—it was exactly the same as he remembered.
For the first time since returning to the past, the crushing weight of regret that had followed him from his previous life began to lift slightly.
He had failed to protect her once.
But now he had another chance.
This time, nothing would take her away.
Elira studied him for a moment before speaking again. "Father is asking for you," she said. "He returned from the northern patrol earlier than expected."
Leon's eyes sharpened instantly.
Northern patrol.
The Great Monster Forest lay beyond the northern borders of Ardentia. Even in times of peace, monsters from its depths occasionally attacked nearby villages. His father personally led many of the patrols that protected the kingdom from those threats.
In the previous timeline, those patrols had been routine.
But now…
Leon felt a strange sense of anticipation rising inside him.
If he remembered correctly, an unusual monster incident would occur near the forest border within the next few weeks.
An event that had once been dismissed as minor.
But with the system guiding him now, even a small event could become an opportunity.
Leon picked up the practice sword one last time before placing it carefully back on the rack.
"Let's go," he said calmly.
Elira blinked. "That's it? No arguing today?"
Leon smiled faintly.
"No arguing."
As they walked toward the palace together, the golden sunlight stretched long shadows across the training yard behind them.
And somewhere deep inside Leon's mind, the system quietly observed.
Preparing the next mission that would begin shaping the future of a fallen prince.
