Seven days before she was reborn, the subjugated princess Xiao Zhaorong overthrew the imperial mausoleum with her psychic powers, vowing to make the royal family pay for its blood debt. She forms a dangerous alliance with Xie Wujiu, a prodigy in the secret service, but she does not know that he carries the secret edict of the late emperor; the mute doctor Liu Ruyan guides the way with a blood letter, the crazy maid Yin Hongxiao secretly delivers the underground palace map, and the confession of the Queen Mother Zhou Yuanzhen is quietly rewriting the ending of revenge. When the wronged soul deep in the imperial mausoleum awakened, she realized: what she was digging was not a grave, but a chain of fate.
