Awoke with a start, my body aching and my mind reeling from the ordeal in the Abyss. As my vision cleared, I realized that the old man had treated my wounds. My body was still weak, but the immediate pain was dulled by makeshift bandages and salves.

The old man stood over me, his dark aura more pronounced than ever. His stoic expression betrayed nothing, yet there was a strange glint in his eyes.

"You have changed," he said, his voice as cold and unyielding as the desert nights. "You survived the Abyss. My name is Eldran, and I acknowledge you as my disciple."

He approached me without another word and placed his hand on my core. His eyes widened in shock, the first real emotion I had seen from him. "Impossible," he muttered, more to himself than to me. "You have no mana core."
Confusion clouded my thoughts. "Is that... bad?" I asked, my voice hoarse.

He checked my body again, his hands moving over my muscles, feeling for any sign of channeled energy. "Your body is a complete mess," he said finally. "I cannot train you unless we fix this."

He explained why this was actually a good thing. "There are three ways to harness power," he began, his eyes intense and unwavering. "First, there is mana, the raw essence of magic. Mana users burn it like fuel, casting spells and bending reality to their will. But for that, you need a mana core, a reservoir within the body that can store and channel this energy." He paused, letting the weight of his words sink in. "Second, there is spiritual power, known as aura. This is the energy that flows through all living things, the essence of life itself. With enough training, one can manifest this power, channeling it through sheer force of will and discipline. Aura users can perform feats of strength and agility beyond ordinary human limits."

Eldran's expression grew darker. "But you, Brat, have neither a mana core nor the capacity for aura as you are now. Your body is shattered, a vessel too broken to hold or channel these energies. This would be a death sentence for most in these lands. However, it presents a unique opportunity."

He lifted his hand, and with a fluid motion, summoned the black flames from before. This time, the flames were encircled by mystical runes, glowing with an otherworldly dark light. "There is a third path," he continued, his voice low and reverent. "Sutra. An ancient martial art that predates both magic and aura. It draws from the center of the spectrum of mystical energies, balancing the raw power of mana and the refined essence of aura."

The flames danced around his hand, the runes pulsating with energy."Sutra is not about burning energy or channeling life force. It is about harmony, about using the very essence of existence itself. Those who master Sutra can wield power that neither mana users nor aura wielders can comprehend. It requires a body and mind forged in adversity, rebuilt from the ground up. And you, have to be reborn in order to master it."

He closed his hand, and the flames and runes vanished. "But before I can teach you Sutra like I said, we must first rebuild your body. It will be a grueling process, but if you survive it, you will emerge stronger. Ready to harness the true power that lies within you."

His eyes bore into mine, a dark promise hidden within their depths. "I will teach you Sutra, but first, we must make you worthy of it."

He disappeared for a moment, returning with several heavy rocks. "This should be enough for now," he said, stuffing the rocks into my clothes. "We will march until we arrive at a certain place. You must carry these weights the entire way."

I looked at him in disbelief. "And if I can't?"

"Then you will die," he said flatly, his eyes cold and unyielding. "I will not help you. I will not stop if you get tired. Even if you get devoured by the desert's beasts, I won't intervene. You must keep up with me, or you will be left behind."

A chill ran down my spine at his words. The sheer indifference in his tone was terrifying. My heart pounded in my chest, and I felt a mix of fear and determination surge through me. The desert, already unforgiving, now seemed even more hostile. Every grain of sand felt like a potential grave.

I clenched my fists, my nails digging into my palms. I knew I had no choice but to follow him, no matter the cost. The weight of the rocks in my clothes felt heavier with each passing second, a physical manifestation of the burden I now carried. My survival depended on my ability to endure this brutal test. Failure was not an option.
Before we started, I glanced back at the Abyss, a shiver running down my spine. It felt like a part of me was still bound to that darkness, destined to return.

Our journey began, and it was hellish. The weights dragged me down, every step a monumental effort. My muscles screamed in protest, and my bones felt like they might shatter under the strain. Each morning, I woke to the sensation of my body bruised and battered, every movement accompanied by sharp stabs of pain.

Finding food was an ordeal in itself. I had to hunt with the weights still in my clothes, my movements sluggish and clumsy. The desert was unforgiving, the sun scorching. I had to ration my water carefully, every drop precious. My throat was constantly dry, my lips cracked and bleeding from dehydration. Eldran, despite his muscular build, moved with a speed and grace that seemed impossible. His tan body cast a long shadow over me, a constant reminder of how far I had to go.

Days blurred into a haze of pain and exhaustion. I stumbled and fell countless times, each fall a brutal reminder of my own weakness. My hands and knees were scraped raw, blood mixing with the sand. The desert was a relentless adversary, the heat merciless, the nights freezing. Sleep offered little respite; I was haunted by nightmares of the Abyss and my family's accusing faces.

Yet, I pushed on, driven by a burning desire for revenge and the promise of strength. Each day, I felt my resolve hardening, my determination growing stronger. The pain became a constant companion, a reminder of the stakes. My body, though weak and untrained, began to adapt to the weights. My muscles, torn and rebuilt, slowly grew accustomed to the strain.

Eldran's pace never faltered. He moved with an effortless fluidity, his footsteps barely leaving marks in the sand. Watching him, I felt a mixture of awe and frustration. How could someone so powerful exist? He was a living testament to the strength I sought, and every moment in his presence reminded me of my own inadequacies.

One particularly brutal day, I found myself on the brink of collapse. The sun was a blazing inferno overhead, and the sand seemed to suck the life out of me with every step. I could barely lift my feet, the weights feeling like anchors pulling me down. I tripped and fell, the impact knocking the wind out of me. For a moment, I lay there, staring at the sky, tears of frustration and pain blurring my vision. But I couldn't stay down. With a guttural scream, I pushed myself up, my body trembling with the effort. I saw Eldran watching me, his expression inscrutable. His silence was a challenge, a test of my resolve. I gritted my teeth and forced myself to continue, each step a defiance against the voice in my head telling me to give up.

The journey seemed endless, an unrelenting march through hell. But with each passing day, I felt a change within me. The weights, though still burdensome, became a part of me. My body, once frail and weak, began to show signs of resilience. My mind, though tormented, started to find moments of clarity amidst the chaos.

The desert, once a place of despair, became a crucible for my transformation. The harsh conditions, the relentless pace, and the constant struggle against my own limits were forging something new within me. I was not the same person who had entered the Abyss. I was becoming something stronger, something more enduring.
One evening, as the sun dipped below the horizon, casting long shadows over the desert, Eldran stopped abruptly. "Wait," he commanded, his eyes fixed on the distance.

I looked where he was pointing and saw them—demons, their twisted forms silhouetted against the dying light. Their skin was a sickly gray, mottled and rough, with eyes that glowed a malevolent red. Jagged horns protruded from their heads, and their bodies were a grotesque amalgamation of muscle and sinew, radiating an aura of pure malice.

"This is your first real test," Eldran said, his voice filled with an eerie calm. "Survive, and you will take your first step toward true strength."

I didn't know what he meant by "survive," but the ominous tone in his voice left no room for doubt. My heart pounded as I stared at the approaching demons, my mind racing with fear and uncertainty.
