What are the characteristics of immortals?

Fairy body has two meanings: first, it refers to this person, who has a fairy fate in the world and still has this natural fate in this life; The other is that there are immortals possessed in this life, and sometimes there are people with extraordinary temperament and spirituality. With the immortal body, both strength and speed have been greatly improved, and we can absorb the power of nature and perceive things around us. With immortality, people can be greatly improved. There are six immortals' eyes, and Miaomushan cultivates immortals. Immortals should not compare with their eyes. Immortals can be cultivated, but immortal eyes can't be obtained.
