"You must be the great existence in charge of the sacred Snow Mountain's inheritance, right? My assessment quota was also given by you?"
Upon hearing Jiang He's words, demoness snow beamed with joy."
"How did you guess it?"
In a sense,"it" was indeed the manager of the Holy Snow Mountain's inheritance.
"It" transferred its consciousness to the Snow Witch, thus allowing the elemental form of the Snow Witch to "come to life."
As for why he did that?
One reason was that it was bored. It had lived alone in the Holy Snow Mountain for countless years, and its only pastime was to watch the snow wolves climb the mountain. It wasn't easy to find an interesting human, so he wanted to have some fun.
The second reason was that he was curious and wanted to see what was so special about the human and his familiar that could sense Cang Xue's will.
Therefore, at first, it pretended to be a human to play with 'Jiang He', but its plan was destroyed.
