The Princess Royal Episode 16

Li Rong helps Pei Wen Xuan, and their mother retrieves his father's assets and land deeds. Li Rong secretly feels happy when Pei tells her that he plans for a future with her. Their happy chat gets interrupted by bad news of the death of all the witnesses in the Qin case. The Princess goes to the Justice prison to meet General Qin Lang. In court, the ministers pressured the emperor to punish the Princess for taking away the Qin prisoners without proper procedure. Li Rong debates with the Justice Minister. While she is willing to accept 30 flogs and seclude herself in Beyan Pagoda to recite scriptures, she asks for the Justice Ministry to be punished for failing to protect the key witnesses and for being uncooperative to the extent of obstructing her investigations. If she still fails to uncover the truth within 20 days, she will leave the capital and never return. She goes into seclusion while Pei Wen Xuan leaves on a secret mission to retrieve military records. (Source: AnastasiaWun at MyDramaList)
