My Harem wants to Conquer the World for Me

"Born too late to explore the seas and too early to explore the stars." This was a line that most people resonated with deeply, and Gray's emotions also resonated with it, even though he had no particular interest in exploring the world. Gray was someone who grew up reading about great conquerors like Alexander the Great and Genghis Khan. He admired their ambition and dreamed of becoming a legendary figure like them. Sadly, he felt he was born in the wrong era to fulfill those aspirations. However, one day while playing a video game, Gray suddenly found himself transmigrating to a new, apocalyptic world filled with magic and horrifying monsters. Instead of feeling fear, Gray was excited - this was the perfect opportunity to follow his grand ambitions. And Gray did just that. He fought and conquered for countless years, building a vast empire through sheer force of will. Yet even as his power grew, his heart grew weary and tired. Still, his empire showed no signs of stopping. It didn't take long for Gray to notice one unsettling thing: his wives had become all too eager in continuing the fight to expand his dominion over the world.
