In a world where magic is king, being a regular human is dangerous. So dangerous that there are very few non-magical humans left, and they only survive with the protection of mages. Mages feel a mixture of pity and revulsion for these un-evolved humans, and call them Zombies, for, without magic, they are lifeless. Most zombies are resigned to their fate, happy to live and work in the shadows of the great mage cities and living simple lives. They keep to themselves to avoid the cruelty and prejudice of some mages, and count themselves lucky to be left alone. The world is filled with powerful magic, dark spirits, terrifying monsters and mages of great power. Zombies should be happy they get to live at all. This is the story of one Zombie who had enough, and, through a twist of fate, finds the means to become stronger.

I thought love was supposed to be my escape—but it became my downfall. The girl I gave everything to, the one who promised forever, betrayed me with a smirk and a kiss... meant for someone else. Not just anyone—but the heir of a billionaire empire. And when I walked in on them, shirtless and laughing, I wasn’t just heartbroken—I was humiliated. She didn’t even flinch. She just said, “You never had a chance.” And the whole campus agreed. Poor. Powerless. Pathetic. That was me. I hit rock bottom that night. I wanted it all to end. But the universe had other plans. A strange light filled my vision, and suddenly, a screen appeared before me: [Activate the ‘Destiny System’? First Task: Spend $5 million in 72 hours.

And they’re not just rich. They’re ruthless. Every step I take, someone tries to pull me down. But I’ve changed. I’m no longer that helpless kid begging to be loved. I have the system. I have the drive. And I’m not just going to take revenge— I’m going to rewrite the game. Not only am I having the power of the system but I am also the lost heir to the system wealth. The only question is: What will I lose in the process? Do I have to take revenge or seek out something more than just teenage revenge?
