“If magic is power, then I'll build my own.” - Adrian.When a genius tech developer dies from overworking, he awakens in a world ruled by magic, ancient empires, and mythical beasts.But unlike the natives who manipulate elemental mana, he is granted a mysterious technology system that lets him reconstruct modern and futuristic tech.Armed with the knowledge of his old world and this game-like system, he begins to revolutionize the magic world. But his rise threatens the very foundation of society, drawing the attention of kings, mages, and forbidden powers that ought not to be offended.As nations clash and secrets unfold, one question remains:Can technology coexist with magic… or will one destroy the other?

When I came to, I had reincarnated along with the base fortress from my sci-fi game. What’s more, I was in the form of the female avatar I used in the game. All around me was an endless ocean, with no iron, no fuel, no energy, nothing at all! No matter how advanced sci-fi technology is, without resources, nothing can be made. Despite this, the natives use some sort of incomprehensible technology called magic, and there’s not a trace of science to be found. Most importantly, I want to eat proper meals for nourishment, not just survive on IV drips! This is the story of a TS girl surviving in a fantasy world together with a super-advanced but spoiled AI administrator.

Birth rates are decreasing. Hope is vanishing. The world has gone gray.Humanity, drifting in quiet collapse, receives an email.Every person on Earth. Simultaneously.The Aegis Mandate.Disguised as a cosmic aptitude test, it triggers The Incident of Separation—a global psychic cataclysm that erases identities, wipes memories, and divides all survivors into three factions: Law, Neutral, and Chaos. Overnight, cities become battlegrounds. Apartments become dungeons. Ordinary people become monsters—or the ones who hunt them.Ragnar Vhagar was just a loner university student. Now, thanks to a system he didn’t ask for, he’s a newly minted Demon King, locked in a crumbling apartment with goblins under his sofa and a glowing soul crystal next to his frozen peas. His new job? Build a deadly domain, defend it from invading “Heroes,” and somehow level up fast enough to not die.Alongside him is Isabelle Thorne, a razor-sharp warrior of few words and one very sharp sword. Their reluctant alliance, born in blood and snark, evolves into trust—and maybe something dangerously close to affection—as they rise together through the layers of the game-like world they’re trapped in.With each conquered domain and defeated boss, Ragnar realizes the truth: the dungeons aren’t meant to crown a winner. They’re meant to break the players. The Law faction wants control. The Chaos faction craves destruction. But Ragnar? He wants something they’re all too afraid to say out loud:Freedom.In the ruins of Kanta’s ogre stronghold, Ragnar and his misfit warband take their biggest step yet—claiming a kingdom, unifying a fractured system, and preparing for what comes next. The Heroes are watching. The gods are stirring. The world is watching a war.And somewhere deep beneath it all... Ragnar is rewriting the rules.

When an S-class elite assassin-raised captain of a special ops suicide squad comes home from a high-stakes Africa mission, he finds himself offered something that could potentially set him up for life- a curious assignment that he could use to finally exit his days of war and slaughter.

Then placed into a high-school setting, Lin Yi is tasked by the chairman of a top-tier multi-billion company with bodyguard duty for non-other than his own daughter, a certain little Miss of said high-school.

His enemies, once ranging from drug lords, mafia bosses, political figures, and national leaders, are soon replaced with spoiled kids who happen to have rich papas and mamas, and Lin Yi finds his intense expertise and high-threat skillset misused, and very underwhelmed…

But he does get a harem cast as diverse as his old enemies, so Lin Yi decides that, for the sake of messing around with girls as an invincible entity in a down-leveled environment, leaving his bloody and death-filled war days behind is something he’d definitely want to strive for.
