Butterfly Gu is an ancient term, a small tribe left behind by the ancient gods.
He uses butterflies as a medium to collect information from the three realms, but because of the greed of the world, he wants to know all kinds of information.
The Butterfly Tribe has been hidden for generations, without any human intervention, and only those with a predestined relationship can obtain information.
The disc tribe is lingering on in the inextricable relationship and darkness of the three realms and is about to perish.
