Demon Slayer: My Million-Swing System

Reborn into the brutal Demon Slayer world, Feng Yu is a powerless orphan, constantly battling starvation. His only hope? A bizarre system demanding a grueling one million sword swings before it grants him any power. Day after day, he grinds, dismissing rumors of flesh-eating demons. But when a horrifying creature breaches his home, he's forced to unleash a blade technique born of endless repetition. The untrained power shatters the demon, but his unique method attracts unwanted attention from the very Corps he yearns to join. Can his \"million-swing\" path truly conquer the ultimate evil?
