The vengeful spirit clad in white hunting attire turned out to be a priest from Shenzhu Shrine involved in some kind of ritual.
Perhaps it was when Hirasaka Hikari went camping outside, he inadvertently came to the area around Shenzhu Village.
And that area had once held a certain ritual; Hirasaka Hikari was attracted by the remnants of the ritual, and eventually became spirited away.
Although he was fortunately found in the end, he was still haunted by the vengeful spirit.
It was also because the Hirasaka family had contacted Master Yutian in advance, or else Hirasaka Hikari would sooner or later be completely eroded, and the time might come when he, controlled by the vengeful spirit, would commit a serious crime.
Similarly, it was fortunate that the priestly vengeful spirit was more interested in eroding the vitality of Hirasaka Hikari; otherwise, if it were to directly leave his physical medium, that would have been a bloody and brutal incident.
