The Phoenix born on the night of the blood moon was named one of the "Ten Evil Stars" by the Department of Yin and Yang. The Su family used the lives of nine women as bait to pretend that she was the "only son Su Mingyuan". After being dormant for eighteen years, she wore a blindfold, muted her voice, and entered the Special Section of the Sitian Prison as a man - this imperial examination was originally a trap for screening sacrifices.
Ninth Sister protects her with her life, the book of life and death has been tampered with, and the earth line formation hides mysteries. She is shocked in the examination room and gradually uncovers the truth: the so-called sacrifice is just a conspiracy by the Yin and Yang Division to plunder the Phoenix bloodline. When the mask shatters and the phoenix fire burns out the evil star curse, she will eventually become a daughter and rewrite the thousand-year destiny of "ten girls as sacrifices".
