With the Trillionaire System, he’ll rise from a forgotten nobody to the richest man in the country. Those who mocked him will kneel. Those who betrayed him will pay.

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.

My CEO wife, Cassandra Solis, has high hopes for me. In fact, she has drafted an elite training program for me. I have to work over 20 hours a day, finish every meal within 3 minutes, and spend no more than a minute in the restroom. "Honey, elites must achieve what normal people can't. Only when you become a true elite can I entrust the company to you." I can feel the major responsibility weighing down on my shoulders. Every day, I devote everything I have to work. Five years later, I've successfully taken the company public. I've also completed Cassandra's hardcore training program. But at the end-of-the-year gala, Cassandra hands over the position of the Executive Vice President—the same one that she's promised to me—to her newly-recruited assistant. Upon noticing my displeasure, Cassandra explains to me smilingly while holding a bouquet of flowers, "Oh, silly you! Having a completely useless boss is the final trial I've set up for you! Once you've completed this trial, I can finally hand the company to you!" But lines of text suddenly flash across my vision. "Oh, poor Harvey! He still has no idea that Cassandra has been training him just so he can earn more money in order to clear off Xavier's debt! Not only that, but she also steals the position Harvey has been longing for and gives it to Xavier! Cassandra really has crossed a line this time!" "You're being too dramatic. Cassandra is just paying Xavier back for his benevolence. She feels guilty for what she's done to Harvey, you know. Once she's done paying back her debt to Xavier, she'll pay attention to Harvey once again and live happily ever after with him." I'm stunned by what I see. Is this the actual purpose behind the elite training program? I'm about to pull out the terminal cancer diagnosis report, but I quickly stuff it back into my pocket. It's a shame that I'm about to die. I suppose that I can't live long enough to see that day.

I had been the top student the school recruited with a full scholarship, while my younger sister, Chloe Stevens, had gotten in through money despite being a poor performer. In my past life, during the college entrance exams, Chloe, who had always ranked at the bottom, suddenly made a miraculous turnaround and got into Royalton College, just like I did. Right after that, she marched straight to the admissions office and reported me, claiming that I had copied all my answers from her. That was impossible. I had a score above 1480 on every single test. The admissions office and teachers did not believe her either. Then, Chloe accused me of using some kind of black magic, saying that whatever answer she wrote down, I would somehow know and copy it. The admissions office made us retake the exam, and somehow every single one of our answers came out identical. I could not defend myself, got arrested by the police, and spent the rest of my life rotting in prison. After being reborn, I studied harder than ever and secured an early admission to Royalton College. Now, sitting in the exam room, I deliberately scored zero on every single test. I wanted to see just how many points Chloe could get without me.
