Two major banes of the underworld, Yun Hua and the Book of Life and Death, accidentally reincarnated. Armed with the ability to eavesdrop on inner thoughts and check fate charts, the person and the book go wild gossiping in the Donglin imperial court. Not only does Yun Hua expose spies, crack the exchanged-daughter case, and foil banquet assassinations, but she also publicly reveals the imperial concubine's illicit affair and the fake princess's true identity, turning the royal family and officials upside down. While gaining merits, rising through official ranks, and getting rich by gossiping, she also keeps her eye on the sickly heir Nangong Yuan, determined to marry into the Prince Su's Estate and become a wealthy, leisurely, and happy young widow.
