My Demon Lord System: I Can Level Up Anything

Loren Grant, a disgraced noble heir, wakes to utter ruin. His ambitious territory, built on a perilous wasteland, was annihilated by monstrous Blood Polluters. Penniless, hunted by a vengeful Demon Lord, and with his last soldiers dying, his future is bleak. But a desperate ritual ignites a terrifying awakening: the dormant blood of a Demon Archduke! Simultaneously, a unique Lord System binds to his desolate fort, revealing its true power: his entire legion can level up by killing monsters, and powerful elemental turrets can be built to slay corrupted dragons! With an army that grows stronger with every kill, Loren isn't just rebuilding—he's forging a demonic empire. His first quest: earn an impossible 10 million in three days to fully awaken his dark heritage. Can this \"failed lord\" leverage his demonic power and unique leveling system to turn the encroaching horrors into his unstoppable, ever-evolving army?
