She is Wen Yuxin, the ominous daughter of the "Kefu" of Dingbei Hou Mansion. She recruits wives into the house to protect the disabled people. Hidden under her cold mask is the obsession to track down the murderous murder of the family. He is Zhang Junhao, the foolish son-in-law, who is actually the orphan of the former prince. He uses the "strategy of calculation" learned in "Yinfeng Pavilion" to deduce the layout and lurk to investigate old cases twenty years ago.
On the wedding night, under the hijab, there was a cold light in his eyes, and she coldly saw through half of the crown prince's order in his sleeve. In the Xiuchundao case, blood spattered in the courtroom, and half of the Hou Mansion jade pendant in the arms of the dead woman in the dry well fit perfectly with her hand. She awakens the "Seven Orifices Exquisite Heart" inherited from her ancestors, has a photographic memory, and has insight into people's hearts; she strategizes and deduce the world based on divine strategies.
Poisonous wine in the Bloody Mansion, rebellion between the loyalist party, memory erasure and smoke... The cold lady and the sinister son-in-law, through the temptation of "love but not being able to get it" and the tacit understanding of "reunion after breaking the mirror", unravel the cocoon of many mysteries. The unsolved cases in the city and the secrets in the court ultimately point to the unjust case of "collaboration with the enemy" in Dingbei Hou Mansion. When the "Seven Orifices Exquisite Heart" turns into a sharp blade to overturn the case, and the "Successful Strategy" sets up a shocking chess game, this "unfortunate" couple in the eyes of the world vows to overturn the conspiracy chessboard of the past twenty years, play chess as a son-in-law, restore the innocence of the family, and determine the world!
