​Gravity is the first enemy. Time is the second. Gods are just variables he hasn’t solved yet. ​Dr. Elian Vance is not a hero. He is a fugitive, a thief, and a father running out of time. ​Once the leading mind of the Federation’s Stellar Engineering Corps, Elian sacrificed his career and his humanity to save his dying daughter, Alara. He stole the Horizon Seeker—a prototype starship—and the galaxy’s most advanced artificial intelligence, A.R.C., fleeing into the forbidden sectors of the universe to find a cure for the Galactic Phage eating away at his child's nervous system. ​He didn't find a cure. He found a gravity well. ​The Horizon Seeker lies broken in the ravine of an alien world where trees are made of iron, storms rain acid, and the atmospheric gravity crushes down at a lethal 8.5 Gs. ​Elian wakes up with a shattered body, a dying power suit, and a terrified realization: Alara is still alive. ​She is locked in the ship’s secure hold inside a heavy Cryo-Stasis pod. She has five years of battery life. But Elian? His suit has fourteen hours. If he dies, the pod eventually fails, and his seven-year-old daughter wakes up alone in a jungle of monsters. ​Leaving is impossible. The pod weighs five tons. Staying seems suicidal. But Elian Vance is an engineer. And he has a plan. ​Science Meets The Divine This world is ruled by beings who channel a mystical energy to split mountains and fly on swords. They view the universe through metaphors of dragons, phoenixes, and spiritual roots. ​Elian views it through A.R.C. To him, their "magic" is just an Unknown Isotope—a programmable, high-energy radiation. To him, a "Fireball Technique" is just inefficient Thermodynamics. To him, a "Flying Sword" is crude Magnetic Levitation. ​Armed with a supercomputer in his brain and a desperation that transcends fear, Elian begins a brutal process of survival. He doesn't meditate in caves to gain enlightenment. He uses the ship’s fabricator to build centrifuges, refining monster blood into genetic mutagens. He surgically breaks his own bones to weave them with carbon-lattice structures, turning himself into a biological tank capable of withstanding the crushing gravity. ​He becomes a monster of science in a world of fantasy. ​The Rise of the Iron Demon Trapped in the lethal jungle, Elian turns the wreckage of his ship into a fortress to guard Alara’s sleep. He subjugates the local giants not with charisma, but with the cold logic of leverage and superior firepower. ​But the light of his reactor pierces the dark jungle, attracting the eyes of the human sects who rule the skies. They see a grey-skinned demon occupying a sacred metal cave. They bring ancient spells, ancestral artifacts, and the arrogance of Immortals. ​Elian meets them with Railguns, Tesla Grids, and Chemical Warfare. ​As the conflict escalates, Elian uncovers the terrifying truth of this world. The barrier in the sky isn't natural. The gravity isn't random. This planet is a Penitentiary. ​The "Gods" living on the floating islands above aren't deities. They are Wardens. And they have the one thing Elian needs to save Alara: the key to the exit. ​He won't bow to the Heavens. He’s going to dismantle them, piece by piece. ​Genre: Hard Sci-Fi / Progression / Base Building / Dark Fantasy. Themes: Fatherhood, Transhumanism, Technology vs. Magic, The Horror of Survival.

Ren Tanaka, the seemingly lazy heir to Japan's most powerful shadow empire, prefers melon bread and naps over corporate warfare. But when terrorists storm his elite academy, the boy who never cared reveals his true nature: a strategic genius capable of dismantling enemies with words alone.

Will the dragon return to its slumber, or will the world force him to burn it all down?

Wei Shao died at the threshold of immortality, betrayed and broken by seven Transcendent cultivators who feared his power. But death was not the end—the enigmatic Sovereign offered him a choice: oblivion or return to the beginning with three hundred years of memories intact. He chose to return. Armed with forbidden knowledge and ruthless pragmatism, Wei Shao embarks on a second life where power matters more than morality, and survival requires sacrificing everything—including his humanity. To save his sister from a tragic fate, he binds corrupted spirits that orthodox cultivators fear to touch. To advance his cultivation, he hollows himself out piece by piece, trading emotion for efficiency, identity for power, consciousness for capability. But true power demands true price. Each advancement strips away more of what makes him human. His emotional capacity—consumed by an Emotion Eater spirit. His sense of self—eroded through the Hollowing. His very existence—dissolved and reconstructed by the spirits he thought he controlled. Wei Shao becomes something unprecedented: a distributed consciousness maintained by three increasingly autonomous spirits, each more human than he is. In a world where cultivation is everything, Wei Shao proves that some paths to power should never be walked. He calculates his way past human limitations, optimizes himself beyond morality, and transcends consciousness itself—only to discover that becoming more than human means becoming less than alive. A dark cultivation journey exploring the true cost of power, the nature of consciousness, and what remains when everything human is sacrificed for advancement. Warning: Contains themes of identity dissolution, emotional absence, body horror, systematic dehumanization, and philosophical nihilism. This is not a redemption story—it's an examination of what happens when someone optimizes themselves out of existence.

Entre ecos, relojes detenidos y palabras que nunca llegaron a pronunciarse, la historia explora el peso de lo no dicho y el momento inevitable en que mirar hacia adentro deja de ser una elección para convertirse en una necesidad.

En Ciudad Orígenes, todo parece brillante y seguro… pero detrás de los anuncios y la propaganda, la Agencia del Cuidado Civil controla a los ciudadanos con mano de hierro. Harkancel, un joven indiferente que ha visto demasiado del mundo, solo vaga por las calles bajas, observando lo que nadie quiere ver: el verdadero rostro de la ciudad, lleno de pecado y corrupción.

When she opened her eyes, she had inexplicably returned to twenty years ago, the first day of the apocalypse escape. "Classmate, you're a Superpower User, right? How about considering joining our special operations squad?" Looking at the man opposite her with sparkling, charming eyes, Xie Ning heartlessly refused: "Thanks, I have a team."
