Kael Ardyn woke up in this world as a great demon. At first, he thought, well… this isn’t so bad. It even felt oddly comfortable in a way he couldn’t quite explain. But that illusion shattered fast. Very fast.He sent his monsters to attack the church, confident they’d handle it. He should’ve known better. That’s when he realized this world wasn’t simple. It had layers. Two of them. The outer layer—weak, foggy, dampening his strength. The inner layer—his powers surged like a storm, uncontainable.He ordered his lesser demons to hunt the humans daring to leave the church. But they were smart. Clever. Each time the world shifted toward the inner layer, they slipped back inside, laughing at his half-hearted attempts. And him? His energy was still nowhere near enough to break through their defenses.Weeks dragged on. Days melted into one another. And then she appeared. A young girl, bold and fearless, is leading the church’s assault. Finally, Kael had more than a glimpse of the people he’d

After finishing his exams, Wang Xiaotian collapsed onto his bed, staring at the ceiling like it held the answers to life—or at least an explanation for his headache. His body ached, yes, but it was the weight on his mind that pressed him down, heavy as lead.Dong… dong… dong… Twelve slow, heavy strokes of the midnight bell rattled through the silent room, each one thudding like a drum inside his chest.And then a voice, deep and unyielding, spoke beside him.“The challenge of Hell Layer Two is about to begin. Challenger, prepare yourself.”“I… I want to say ‘No.’ Can I? Seriously? Ugh, this system is impossible!” Wang Xiaotian groaned, flopping onto his side. “How long has it been since the last task? And now—another one? A hell-level challenge? I just got back after spending eight centuries on Hell Layer One!”“No. The challenge begins.”And ju

Kael Ardyn spent the next few days thinking he was living a quiet life. No missions arrived. No alarms shattered the mornings. No sudden death traps popped up from the War God System. The world seemed… almost peaceful. Almost normal.At least, that’s what he thought.One morning, he woke up feeling heavy. Not just a little tired, but like someone had poured lead into his bones. His limbs barely moved, his chest felt tight, and each breath was shallow. Even lifting a hand felt like lifting a boulder.He rubbed his eyes. Tried to sit up. But the weird, sinking sensation only got worse. His pulse thudded in an odd rhythm—neither fast nor slow, just hollow.Something was wrong.Inside him, the biological mecha had started to grow.It began subtly. A warmth was creeping through his veins, like molten energy simmering beneath the skin. Then, the feeling became impossible to ignore—a coiled, hungry presence that seemed alive. This wasn’t ordinary equipment. Not even close. It fed on blood to

Evening settled over the Arctic Laboratory. Kael Ardyn pushed back from his bench. Ten hours remained before the forty-eight-hour limit, but instead of diving into another experiment, he guided Kelly back to his room. The silence between them was comfortable, heavy with unspoken thoughts. For once, the endless hum of machinery, the stress, the constant countdown—it all felt distant. That night, they simply existed in the same space. Peaceful. Fragile. Human.Morning came too soon. Kelly returned with him to the lab, her cheeks faintly flushed from the night. Around them, more than a hundred experimenters worked in near-silent frenzy, hands moving with precision born from exhaustion, eyes hollow with determination. The lab was alive, but not with comfort. It was alive with tension, the kind that makes your chest ache and your stomach knot. Hope and despair were tangled so tightly together that you couldn’t tell where one ended and the other began.Forty-seven hours and forty minutes in

Kael Ardyn wandered the campus, his thoughts heavier than his footsteps. The War God System hovered over his life like an invisible guillotine. It didn’t rush him. It didn’t threaten him. It just waited. Silent. Patient. Watching. As if it already knew how things would end.The stronger Kael got, the more he felt the danger brewing inside him—the dormant demon lurking beneath his skin. Power didn’t feel comforting anymore. It just made him aware. Each breakthrough sharpened his instincts, but also the unease gnawing at his chest.If he didn’t destroy the War God System one day, freedom would forever be a lie. He’d be trapped in a loop, pulled forward and reset over and over. The thought made his skin crawl. To live a thousand lifetimes repeating the same struggles—he shuddered at the idea.Sure, the system’s agent had given him allies. Some powerful, some terrifying. The scariest? Destruction Girl. A name whispered across worlds, a being that had once annihilated the ancient Rune Worl
