The Imperial Astronomer, Kuai Duo, was investigating an unusual activity in his dig when he and his assistant were attacked. When the Marquis returned to the Capital, Kuai Duo's party were not among them. The Princess of Dongxia caused the Marquis's second son's carriage to topple over. Zhinu and Gousheng rescued him, only to tie him up for questioning. Zhinu's mother eventually discovered him and returned him to his family. That night, Kuai Duo returned to his family home and urged them all to pack up so they can leave that very night, but it was too late.
