Take the Elves to Cultivate Immortality

This elf, I see that you have clear bones and are a unique genius in cultivating immortals. Why not follow me in your cultivation? 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 cultivate immortality, once you survive the catastrophe, you can transform into a human being... Menas, Sanaido... Come with me to cultivate immortality! ! ! ! ! ! (Note: Original plot: References characters from comics + animation, but the things they do will be different)
