During the Wanli period, there was a huge water transport case, and the blood of Dali Temple judge Shen Qingyue was splashed in Yongjing, leaving only a red sandalwood box and a secret order to kill everyone. His daughter Shen Zhitang was transformed from an official daughter to an imperial prisoner overnight, and was forced to embark on the road to escape.
The code in the box points to "Nine Masters" Wei Zhen, the eunuch who has great power in both the government and the public. The pursuers behind him are the traps of the eunuchs all over the government and the public. In a desperate situation, the censor Yanqing, whose identity is a mystery, and the mysterious organization "Shadow" appear, using flesh and blood to pave a bloody way for her to survive. From Yongjing to Suzhou, from the canal to the mountains, every step is like the tip of a knife dancing, and every step of the way, loyal souls are seen falling.
However, when Shen Zhitang narrowly escaped death and finally got to the core of the truth, he was shocked to discover that the biggest conspiracy was not corruption, but a thievery that shook the country. The blank imperial edict obtained with countless blood is the last weapon, and it may also be a reminder. Trust and betrayal, loyalty and betrayal, right and wrong, are completely blurred in the mist of Jiangnan.
The orphan girl's blood edict, the eunuch is in power. This is a game of life and death with the world as a chessboard, and she is the last piece on the chessboard and the one who holds the chessboard. When the palace gate of the Forbidden City opens for her, what awaits her is the avenging of her injustice, or is it the end of her life?
