Lu Zhaoning, the true eldest daughter of the Lu family who has been missing for ten years, suddenly returns. Everyone thinks she is a "foolish girl" who has suffered hardships in the deep mountains, but little do they know that she has long become a true disciple of Cangwu Mountain, with pinnacle-level metaphysics skills. On the night of her return home, she stops the pouring rain and forcefully crashes the wealthy family banquet, publicly exposing the hypocritical mask of the fake eldest daughter, Lu Ruowei. As her parents fall into comas, family assets are usurped, and evil formations appear one after another, Lu Zhaoning step by step uncovers the mastermind behind the scenes, the "Shadow Alliance", and discovers that all of this is actually related to her missing master and the Cangwu Xuantian Remnant Decree.
