Li Wudao, a social animal who died suddenly in a rental house, opened his eyes again and became the new eunuch "Xiao Lizi" in the cleansing room of the Daqian Dynasty. Before the sharp pain in his crotch dissipated, he discovered that he was not the only one who had traveled through time - the goddess Qin Waner, whom he had a crush on in college, had become the emperor's favorite Princess Changping.
A bronze mirror that oozes blood, a scarred eunuch with a fox tail hidden in his shadow, and the mysterious legend about the "true princess" deep in the cold palace, tie two souls from another world tightly in this magnificent cage.
He is a useless man without any foundation, and she is a princess who can't help herself. When the dark red moon climbs into the sky, the past that appears in the mirror contains the truth about time travel and a conspiracy that can subvert the dynasty.
"Li Wudao, do you recognize me?"
"Wan'er, I look like this now..."
The deep palace is treacherous and shocking every step of the way. He wanted to survive among the eunuchs, and she wanted to protect herself in the struggle for imperial power. But when the bloody words on the bronze mirror pointed to the "Phoenix Seal", and when the scarred eunuch's fangs were exposed, they discovered: this time travel was never an accident, and they were already the dead pieces on someone else's chessboard.
The love between a rootless eunuch and a princess in distress begins with the blood in the ablution room, and ends in the machinations illuminated by the red moon, to an unknown ending.
