Refining the Body into a Sword to Cut the Sky

I was mediocre in my previous life, but now that I have come to this vast world of immortal martial arts, I will live up to my expectations and stand proudly at the top of the Nine Heavens! Cultivate the immortal sword body and master the supreme sword technique! The evil cultivators are wreaking havoc with one sword strike, and I alone defeat hundreds of families, and I am the king! Who is at the top of the chaos among the six tribes? The sword destroys all the immortals and steps on the ninth level!
