In the fifteenth year of the Republic of China, Shen Qingyi, a female forensic doctor who returned from studying abroad, received the news that her sister had hanged herself mysteriously in the Luo family, and a cold marriage letter - the Luo family forced her to marry on her sister's behalf in the name of happiness.
On her wedding night, when she put on her wedding dress, what was waiting for her was not her husband, but a corpse with blood oozing from its orifices.
To prove her innocence, she cut open her "new husband's" chest in front of everyone in the Luo family. A scalpel cut out a jade pendant that was supposed to be buried with my sister, and also cut out a sin that had lasted for hundreds of years in a deep house and compound - exchanging life for immortality and human sacrifice.
And she was the last "Yao Yin" they were looking for.
Her enemy is the entire Luo family; her only variable is the man who returned from the battlefield - the warlord Luo Jingting. He was cold and stern, and placed her under house arrest in the West Courtyard, but secretly blocked murderous attempts for her again and again. The suppressed pain in his eyes and the blood of his sister on his hands made it difficult for her to tell: was he her enemy or her last guardian?
When the truth is revealed, love and hatred become entangled in a deadly situation. She used her body as a blade to lay the final plot, betting that he would betray the entire family for her, betting that a decadent era would eventually be burned to death by blood and fire.
This is a redemption in the name of love, and a journey that ends in death. And dawn will eventually come.
