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.

Set after the war between the Dragon Emperor and the Blood Emperor, in which the two emperors united to protect all realms and the underworld. In a small world where no immortal beings dwell, a married couple lives with their only son.

Or will he end up losing his own life? This is the story of a young man named Tian Sen, who walks a bloody path to discover who he is and where his parents are. But he must become stronger to reach a point where even fate itself cannot control him. “Why? Why don’t they care about people like us? Why? I, Tian Sen, will not accept any of this. I will walk toward the summit even if my hands are drenched in blood. Loneliness will not let me be swayed by the nonsense called fate!”

Bima is just an introverted, scrawny kid used to living behind a gaming screen and being a constant target for body shaming. But his life takes a drastic turn when he wakes up in a ruined city crawling with zombies. In the midst of the chaos, something even stranger than the apocalypse emerges: the "Single Survival System," which hits him with absurd missions likes maintaining an ideal BMI, getting revenge on his bullies, and landing his first kiss. Every mission isn't just a ridiculous challenge; it’s a matter of life and death. Forced out of his comfort zone, Bima must face his dark past. He crosses paths with Donny, his former bully who is now a zombie, and Kevin, an ex-gym influencer who has transformed into a fanatical cult leader obsessed with the perfect physique and extreme protein intake. Amidst the chaos, Bima meets Lia, a tough convenience store clerk who harbors a deep-seated trauma toward food. Together, they survive nonsensical threats, ranging from zombie food vloggers obsessed with livestreaming death to grotesque mutants lurking underground. But the madness is only the beginning. Bima’s reckless actions catch the attention of a far more dangerous entity: the Master AI Fitness Freak, an artificial intelligence that views humans as inefficient unless they meet extreme nutritional standards. With the help of Riska, an AI with cold, business-like logic that shares a secret connection to Bima’s past, the battle shifts into a clash of ideologies: perfection versus happiness. In a world that worships muscles, protein, and ruthless efficiency, Bima fights back in an unexpected way, using Indomie as a symbol of balance, hope, and humanity.

She was a mad scientist of the base where uninfected humans habitats to survive from the outer world. While she is burying herself with works, I decided to be the useless child and the only one she has. Isn't it amusing! Being treated as the daughter of a crazy woman who is obsessed with antidotes. Even after failing hundreds and thousands of times. She should know my well-being but she didn't. No matter how much of a genius I am, it's worthless! I am still garbage in her eyes...!

Well, that is what I thought before the zombies conquer the base and being forced to drink a certain red liquid which is the antidote! Alast, being thrown into a foreign system. ________________________________________________________________________ From the useless garbage to the only human that holds the opportunity to change the world.
