Furthermore, due to having refined the Celestial King Divine Pill and other Heavenly Materials and Earthly Treasures previously, Gu Yuan's Divine Soul essence also possesses a trace of the Yin Spirit foundation.
Therefore, even if some other Yin Spirit giants came, as long as Gu Yuan intended to conceal himself, those who shouldn't be able to see through him still couldn't.
Unless it's someone like Jade Sheng Daoist, the elite among Yin Spirit giants, or even someone as capable as Danxia Ancestor, of Yang Spirit caliber, who could discern some of Gu Yuan's background.
Profound Origin Daoist indeed possesses the essence of a Yang Spirit power, but currently, he is reduced to barely a wisp of his former soul, with less than one percent of his lifelong cultivation remaining.
As a result, his so-called Dharma Eye Divine Techniques are greatly diminished, so it's normal that he cannot see through Gu Yuan.
