Good-For-Nothing Swordsman

I woke up due to peeing, and I hated that I was a swordsman. I once secluded myself in the mountains and forests for ten years, keeping company with heaven and earth, and friends with swords, just to seek the unity of man and sword and the ultimate in martial arts. However, the only martial arts in the world is fast! One yin and one yang are called Tao, and one person and one sword can cut off the grudges.
