System Mania! - Chapter 15: All in the name of survival

Lu Xiao had followed his master for eighteen years, excelling in both medicine and martial arts.After five years of military service, he returned to the city to search for his origins.Faced with flashes of knives and shadows of swords, he was decisive in killing, dominating everyone.When it came to the matters of the heart, he said, “Still… the Young Miss is the best.”

In a world where 80% of humanity has awakened supernatural talents, life is a brutal competition.College loser Kim Do-hyun is barely surviving on game bots, instant noodles, and debt. That is, until a government-mandated awakening throws him into the spotlight… only to declare his power total trash.Cloning? Level one? Cooldown? One body? What a joke.But this clone is real. It sweats. It works. It eats. And when it trains… Do-hyun's stats increase.Now, while the clone grinds 24/7—running, working, even getting beat up—Do-hyun chills in bed, reaping the rewards.His strength rises.

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.
