Primordial Villain With A Slave Harem

I found myself transported to a fantasy world and reborn as a Primordial, a race renowned for their adaptability. Rather than stepping into the role of a hero, I opted for a more methodical, safer, and slower approach. Join me as my story unfolds, chronicling my growth in strength, exploration of this new world, accumulation of wealth, and encounters with charming women. The protagonist is not a psychopathic villain but a scheming, calculative, and opportunistic individual who rarely faces moral dilemmas, particularly concerning those he doesn't care about. This novel draws very loosely from "Slave Harem in the Labyrinth of the Other World," but I've ensured that it includes numerous differences to set it apart.
