Void Lord: My Revenge Is My Harem

In a world ruled by mana and bloodlines, John White was born with none. Reborn from Earth into a noble family, he became the forsaken son of a duke (a bastard) bullied by siblings, ignored by servants, and banished at fifteen like trash. Two years later, he's dragged to a mana mine to be quietly killed by his brother's lackey. But fate has other plans. Deep underground, an ancient abyss-grade ring awakens. It merges with Earth’s forgotten technology with the world’s magic. Fueled by pure mana, it unlocks the Black Hole magic, granting him power never seen before. From a worthless outcast to a terrifying Void Lord, John begins crafting magical tech tools that warp reality itself. His enemies have no idea what’s coming. Will he burn his past to ashes… or rebuild the world in his own image?
