Dong Lu's Revenge

Cheng Donglu seeks revenge for her sister Cheng Shu, who was brutally killed by the princely mansion. Saved and trained for three years by the master of the Wanxiang Pavilion, Qin Heng, she disguises herself as a courtesan to infiltrate the mansion. Together with the seemingly frail Qin Heng, she uncovers Qin Hanzhang's crimes of conspiring with the emperor and embezzling military supplies. They ultimately expose the royal conspiracy, kill their enemies, and help Qin Heng achieve his revenge.
