In the 437th year of Pingqi, Bai Luotang, the Qingqiu Saintess, died beneath the arrow of her lover, Yun Ji.
In the 760th year of Pingqi, Bai Yi appeared out of nowhere in the Three Realms with her Qingfeng Pavilion, belonging to no faction.
As rumors of Qingfeng Pavilion's growing fame spread, Yun Ji placed his hopes of finding his beloved in Bai Yi. He brought a generous sum of money and asked the mysterious newcomer to find his lover.
At their first meeting, Bai Yi feels that the man before her looks familiar, but she can't recall where they met. As the two investigate a case together, strange events keep occurring: young heirs from various clans vanish one after another, demons that have slept for a thousand years awaken, and an eerie figure appears in their minds...
As these events unfold, Bai Yi's origins gradually come to light, and the mysteries surrounding the fall of the Qingqiu clan and the death of its Saintess centuries ago begin to unravel.
