How about the skill of changing the seven dragons into immortals?

Yes, but I suggest changing to ghost seven.

See if it's human 7, ghost 7 or fairy 7. Let's talk about Ghost 7 again. Ghost seven skills can choose to protect the body easily. Discard physical attributes in exchange for fairy resistance, spell evasion and anti-Lingbao damage. Secondly, the choice of Ghost Seven is easy, because the initial value of Ghost Seven determines that it is more sensitive than chasing souls.
