My interracial harem of beautiful queens - Chapter 54 Royal Arena: Sierra (R-18)

In a world without gods, where the laws of magic are written by the mages themselves, balance is fragile, and darkness reigns. Multiple dimensions surround it, watched by beings with dark and greedy intentions. This is a magical universe, unstable, marked by constant changes, betrayals, and bloodshed. At the center of it all, an ordinary man emerges, carrying a biochip capable of deep analysis and data recording. With it, he embarks on a relentless journey of genetic enhancement, seeking to ascend beyond the limits of existence. Without divine protection, without charms to shield him or overwhelming powers, he must survive in a world where threats are ever-present, and the fight for survival is relentless. Here, the only rule is to conquer or be consumed. A dark fantasy filled with dangers, evolution, and the relentless pursuit of supremacy.
