My Concubines Don't Bear Heirs—They Build Warships, and I Conquer Gods

Poisoned on day one, crushed by corrupt ministers, and my only "system" is a fertility-driven tech tree. I thought I was doomed to a life of humiliation—until my royal guard's rusted chainmail evolved into Rune Battle Armor, crossbows turned into star-shattering cannons, and sword cultivators ascended into Earth Immortal war generals. While my neighbors are still sharpening steel, my floating armada already blots out their sun. This isn't a harem farming sim—it's technological annihilation. The MC transmigrates into the worst possible start: a ticking poison counter, a hollow throne, zero military authority, and a system that offers no cultivation manuals, no cheat skills, and no instant power-ups—only one rule: produce heirs to unlock military tech nodes. So instead of palace intrigue, this story goes full "warmongering tyrant" mode: Armor tech: Rusted iron → Rune Battle Armor Mark I → Divine Martial Exosuit Mark V Firepower tech: Crossbows → Rune Hand Cannons → Rune Artillery → Celestial Punishment Star Destroyer Unit evolution: Golden Core Sword Immortals → Nascent Soul War Gods → Kunpeng Mecha → Earth Immortal–Class Star Generals Every upgrade is earned through story-driven progression, not random handouts. The final act isn't a coup—it's an interstellar crusade. Floating warships cross borders, cannons aim at the divine realm, and a puppet emperor becomes the very tyrant the world feared he could never be.
