Not only could he activate High Spirit Vision at will, but it was also comparable to having x-ray vision or Thousand-Mile Eye, ordinary mundane objects couldn't obstruct Tao Qian's sight at all.

It's known that many people in the Cultivation World practice "Pupil Skill" Divine Skills, but few succeed in mastering them. Not to mention a gift like High Spirit Vision, even reaching the level of Thousand-Mile Eye usually takes decades for most people.
