Feng Jun had indeed once been astonished by Sofia's x-ray vision. The day he kidnapped her, he didn't have time to check her aptitude, but on the day he released her, he really looked into it—her aptitude was average, she only had a unique talent called the Eye of Disillusionment.
The Eye of Disillusionment exists in the mobile phone realm as well, but it rarely appears on cultivators. Most of the time, it manifests in spirit beasts.
But this "most of the time" is just a general reference; the Eye of Disillusionment, in essence, is an extremely rare talent, even amongst spirit beasts. For instance, in a thousand purple-gold eagles, only one might have it—and it's limited by usage.
The kind without usage limits is even rarer, let alone appearing in human cultivators.
