I Have a Sword That Is Invincible in Heaven and on Earth

I have a sword that can destroy ghosts at the bottom, kill people with the middle, and kill immortals at the top. Travel through a foreign land and awaken your unparalleled understanding. I have a photographic memory of the skill secrets, no bottlenecks in practice, and full combat talent points. Cold-blooded and ruthless, decisive in killing. One sword can defeat the demons and monsters. If they are still there, use two swords.
