The Sword-Washing Manual

So what if I can't use mystical arts or divine powers? Your magic may reach the heavens, but I can still cut it down with one sword strike! A boy born with an ancient sword pill, and a defiant rise to power as he slays immortals. I have a sword that can cut down heaven and earth!! (The first twenty-odd chapters aren't very good, so please bear with them. Things will get better as the story goes on.) Reader group: 220785545
