The Juggernaut System in a Zombie Apocalypse

Waking up amidst a burning city swarming with heart-glowing monsters, I was just a civilian in a cruel, steam-powered apocalypse. Death seemed inevitable, my ordinary life a distant memory as fear gnawed at my resolve. But when my hand instinctively grasped a discarded katana, a forgotten power surged to life: The Juggernaut Inheritance System. My first terrified, clumsy kill wasn't just survival; it was my first step on a bloody path to becoming an unstoppable Blade Master. Forced to train and fight, I've earned the title 'Sword Saint' by carving through countless Kabane and treacherous humans who sought to betray me. Yet, as I level up, unlocking devastating new skills, a chilling revelation emerges: This world is just the beginning. My Juggernaut's blade is destined to cut through not one, but many apocalyptic dimensions, each more perilous than the last.
