When the apocalypse came, she lost everything. Starving, hunted, and desperate, she trusted the one man she loved… only for him to betray her in the cruelest way possible. He stole her last supplies to please another woman and left her to die in a sea of the undead. But death wasn’t the end. She woke up days before the world collapsed. After cutting ties with her ungrateful ex and his parasitic family, a mysterious voice awakens in her mind, LUS, a Level-Up System designed to help her survive the coming end. With knowledge of the future and a system guiding her every move, she begins to prepare. She stockpiles resources, builds a base, and learns how to fight back against the horrors that once destroyed her. And when the apocalypse arrives again… she’s ready. But survival isn’t the only thing waiting for her in this new life. A silent killer who watches her like prey. A manipulative genius who wants to unravel her secrets. A gentle protector who sees the girl she hides. And a dangerous man who thrives in chaos. As the world burns and power shifts, they’re all drawn to her, each with their own motives, each with their own darkness. Even her past refuses to stay buried. Because now, the man who once abandoned her is back, broken, desperate, and begging for a second chance. Too bad she has no time for regrets. Not when she’s busy rising to power… and building a kingdom in the ruins of the world.

He was supposed to be nobody. Born with crippled spiritual roots in the weakest corner of the Mortal Heaven Continent, he spent his early years mocked by peers, dismissed by elders, and written off as a waste of a bloodline. The world had a plan for people like him — obscurity, mediocrity, a quiet death at the bottom of the cultivation ladder. Then the System arrived. Rude, chaotic, and absolutely unhinged, the Infinite Chaos System begins issuing missions so absurd they border on cosmic comedy — slap an arrogant Young Master, steal from a forbidden ruin, insult a Heavenly Lord to his face. And somehow, at the end of every ridiculous task, he walks away stronger than before. What begins as a shameless scramble for survival slowly reveals something far more terrifying. His talent isn't crippled. It was sealed. His bloodline isn't ordinary. It was buried. And the System that appears to be helping him? It was never designed to help anyone. As he rises from a forgotten boy in a forgotten kingdom to a figure that shakes the foundations of all Nine Realms — and the ancient dimensions lurking beyond them — the truth peels back in layers. The history of the cosmos is a lie. The gods who rule from their thrones are terrified. The first user of his System already conquered everything and nearly destroyed it all. And somewhere at the end of every road, a question waits: what do you do when you've beaten every enemy, unraveled every secret, and the universe itself asks you to become its next ruler? He laughs, pockets another ancient treasure, and causes more problems.

I picked up a system with my sister. The system said only one of us could bind to it, and the other could take twenty million dollars. My sister shoved me aside and chose the money. Ten years later, she squandered everything and ended up homeless. Relying on the luck the system gave me, I excelled in my studies, climbed the career ladder, and reached the peak of my life. Driven by jealousy, my sister stabbed me to death at my birthday party. When I opened my eyes again, I was back to the day we found the system. This time, she said without hesitation, “Luck is too intangible. I’ll take the loss. You can have the fortune.” I knew she had been reborn, too. What she didn’t know was that the luck granted by the system always came at the cost of one’s lifespan.
