In the modern world, everything has value. Bodies. Time. Love. Shame. Trauma. Information. Even human morality itself. Gavin Valerio finally realizes that truth after his life is destroyed in public. As the poorest student at Riverton University, Gavin loses everything in a single night. His girlfriend sleeps with another man, the video spreads across the university’s social platform, and his humiliation becomes entertainment for thousands of people. In a city where money defines status and status defines reality, someone like Gavin was never supposed to matter. Then, at the absolute lowest point of his life, something awakens inside him. Devil Capital System. A mysterious system that grants him access to unlimited capital assets. Money. Liquidity. Institutional networks. Influence. For the first time in his life, the world’s doors begin opening for him. But the System comes with rules far more terrifying than simply spending money. Because to the Devil Capital System, everything must generate value. Wasteful spending is punished. Emotional decisions are considered weakness. Even love itself can become a threat to system stability. As Gavin descends deeper into Riverton’s hidden world of business mafias, elite banking circles, luxury prostitution, viral media manipulation, and institutional power games, he begins to understand something horrifying: Capitalism was never just about money. It is the mechanism humanity uses to assign value to one another. The richer he becomes, the more Gavin is dragged into a brutal ecosystem built on influence, desire, social manipulation, transactional relationships, information control, and people willing to sell pieces of themselves just to survive. And as Gavin rises higher through a world where everything has a price, he begins to face a far more dangerous question: If value is what controls civilization itself... then who truly has the right to decide what something is worth?
