The morning sun filtered through the cracks of the ruined hall, scattering fractured rays across the stone floor. Dust swirled lazily in the golden light, suspended like tiny spirits observing Kael as he knelt there. Each breath he drew rasped harshly in his lungs, every movement a dull ache that reminded him of the weakness of his mortal body.
He had been told since childhood that he was ordinary. Weak. Mortal. A human without dantian—without spiritual roots. Without those, there was no qi to cultivate, no immortal techniques to master, no chance to rise among the great cultivators whose names were spoken with awe across the lands. He would live and die as any other mortal would, insignificant and forgotten.
And yet, here he was, alive in a world where such limitations were meant to crush men like him. Not because he was special, not because he had extraordinary talent, but because he had something else: a Soul Sea.
It was a void within his chest, a reservoir of essence that functioned differently from a dantian. It could not strengthen his physical body, could not give him the speed or endurance of a seasoned warrior. It could not turn him into a storm of fists, fire, or lightning. But it could store knowledge, power, and potential. And most importantly, it could carry runes—the ancient, forbidden language of power.
Kael's eyes fixed on the scroll in his hands. A Grade 1 ancient runic scroll, fragile with age, its paper almost translucent and crumbling at the edges. It had been hidden beneath the floorboards of this abandoned hall, a remnant of a sect that had long since fallen. The ink was faded, but the runes themselves shimmered faintly, as though aware of the presence of a worthy mind.
The first rune he intended to master was simple in design: Earth Wall. Even a seemingly simple rune, however, carried weight beyond mortal understanding. Runes were not merely symbols; they were a language older than the gods, a code through which the world itself could be manipulated. To craft one was to speak with existence itself, and a single mistake could shatter the Soul Sea, leaving the body intact but the mind lost forever.
Kael inhaled slowly, steadying himself. His hands hovered above the scroll. This was not a moment for hesitation. Every moment spent doubting could be a moment too late.

Studying the Rune
Understanding a rune was the first, and perhaps most critical, step. Kael traced the symbol with his finger, observing its curves, its angles, the subtle connections between each line. The scroll did not just teach the form—it pulsed with energy, resonating against the Soul Sea as though it were alive.
He spent the first day memorizing the rune, closing his eyes and imagining it forming within him. The Soul Sea hummed softly, responding to his concentration. It was as though a small piece of the universe itself waited inside him, ready to accept the imprint of knowledge.
By the second day, he began practicing the symbol on scraps of parchment. The repetition was tedious, but necessary. Each stroke had to be perfect, for imperfection in understanding would lead to disaster. Kael could already feel the strain of holding the concept in his mind. His Soul Sea pulsed, a reminder that even learning carried a price.
By the third day, he was ready to engrave the rune into his Soul Sea itself. He knew the dangers: the Soul Sea could fracture under pressure. One crack could mean insanity; a deep fissure could erase his memories or even render him incapable of cultivation entirely. Yet he could not advance without this step.

Engraving the Rune
Kael closed his eyes and called forth his essence. The Soul Sea shifted, ripples spreading across its inner void. He visualized the rune, its lines flowing with his intent, each stroke guiding the essence. Pain shot through his head, sharp and insistent, radiating down his arms and chest as the rune attempted to carve itself into the living vessel of his mind.
Small cracks appeared like spiderwebs across black glass. Sweat ran down his face, and his breath came in ragged gasps. "Focus… essence… control…" he muttered, forcing every ounce of willpower into the task. The Soul Sea resisted, protesting the intrusion, threatening to shatter.
Time became meaningless. Hours passed in what felt like minutes. Each second was agony; each movement of the mind a test of endurance. Kael's consciousness screamed to stop, to abandon the attempt, but his resolve held.
And then, faintly, he felt it settle. A glow pulsed within the Soul Sea, subtle but steady. The Earth Wall rune had anchored itself, etched into the core of his being.
Kael collapsed onto the floor, trembling. His body was exhausted, his lungs burned, but the Soul Sea was intact. One rune mastered. And yet, even now, the lesson was clear: this was only the beginning.

Understanding the Limits
Kael's mind raced as he reflected on what had just occurred. At his current stage, the Soul Sea could hold only four runes. Four. A small arsenal for a mortal with ambitions far beyond his body's limitations. And even a single rune demanded focus, essence, and willpower beyond what ordinary cultivators imagined.
He understood the danger of overextension. Ancient runes drew upon life force directly. Human-crafted runes used materials for fuel and were less dangerous, but also less potent. And the higher-grade runes—the ones monopolized by powerful families—were forbidden to outsiders. Those scrolls were treasures, jealously guarded, often requiring the destruction of a family or the death of a key member just to acquire.
Kael would need to find, earn, or steal each scroll. He could buy Grade 1 runes for ten spirit stones, Grade 2 for a hundred, but money was meaningless without the capacity to comprehend and engrave them.

A Mortal Body, A Mortal Price
Even with the Soul Sea, Kael's body remained mortal. He could run out of breath in moments, tire from minimal exertion, be struck down by a sword, knife, or even a strong fist. The Soul Sea could not protect him physically—it could only amplify his mind, his mastery of runes, alchemy, and strategy.
This limitation shaped his path. He could never compete with cultivators in brute strength, but he could manipulate the battlefield, create barriers, summon runic weapons, and trap his enemies in effects they could neither anticipate nor endure. He could become the unseen hand controlling the flow of war, the mind behind the power.

Kael's Resolve
He slowly rose, brushing dust from his clothes. The glow of the Earth Wall rune pulsed faintly beneath his chest, a silent heartbeat of potential. Kael understood the road ahead: mastering the Soul Sea, acquiring new runes, pushing past the limits of mortal comprehension, and growing stronger than those who had underestimated him.
He would survive. He would endure. And he would rise, step by step, rune by rune.
The first rune glimmered softly, a warning and a promise. Kael's journey had begun, and already, the world seemed larger, more dangerous, and infinitely more fascinating than it had before.
The hall remained silent around him, but Kael did not notice. Within him, the Soul Sea hummed, alive with power, and Kael knew that no force in the world would stop him from claiming the runes that awaited.
He was mortal, yes. Weak, yes. But he had the Soul Sea—and with it, he could challenge destiny itself.
