One was brought up in the mountains by his mother since he was a child. In order to avoid the pursuit of various immortal sects, he was named Sun Fan (I hope he is ordinary and does not get involved in this dispute)+; the other is from a famous immortal family. He has had no worries about food and clothing since he was a child, and he has free time to learn immortal magic. Later, he met a young man dressed in white in the mountains (his mother was poisoned and killed. This pitiful little boy, although young, is so remote and cold that it is difficult to approach.)
Idea: I still had some time when I finished writing the essay for the English exam. Unknowingly, I was in a daze, and a poem "I once thought that being passionate would harm the holy life" came into my mind. Based on the name of the homophonic group, I conceived the story from it.
