Once Upon a Time There Was a Peach Blossom Fairy

Once upon a time there was a Peach Blossom Mountain, a Peach Blossom Temple on the Peach Blossom Mountain, and a Peach Blossom Fairy inside the Peach Blossom Temple. (Eternal Life, light novel) The young soul travels to a different world. This world has martial arts and literature. Warriors can hurt people by picking leaves and flying flowers. The scribes recite visions that imply murderous intent. But he finds that he seems to have become the only "immortal" in the world. He is as old as the sky, lying in the clouds and watching the clouds roll and relax.
