Take the elves to cultivate immortality

Introduction: This elf, I see that you have clear bones and are a unique genius in cultivating immortals. Why don't you practice with me? I guarantee that you can kill the Phoenix King with one strike! ! ! In fact, this is not the point. The point is that if you practice immortality, once you survive the catastrophe, you can transform into a human being... Menas, Shanaido... Follow me to become an immortal! ! ! ! ! ! (Note that the original plot quotes characters from comics and anime, but the things they do will be different)
