The Marquis of Dingbei’s household is framed for treason, and every member is sentenced to death.
On the eve of the execution, Yan Wujiu, the legitimate daughter called the “Demon Star” who supposedly died sixteen years ago in a fire at the Observatory, returns. She storms into the prison with a blade in hand, and overnight, more than a hundred people vanish into thin air.
Wei Yingzhi finds the execution ground empty and is determined to make the Yan family’s guilt stick. She plans to use that very infamy to enter the capital: pose as someone’s fiancée, reopen a twenty-year-old case, and lure out the true culprits who framed the marquis’s household, one by one.
She has calculated every move under heaven, but never expected that the scholar posing as her husband would be carrying a jade seal belonging to the late Emperor Zhao’s orphaned heir.
The Demon Star appears in the dark of night. The east grows pale, and daylight is near.
