Episode 17 recap: Xie Jingshu is love-brained.

After entering the secret room, Li Mengjue and the others discovered that the body in the secretary's office seemed to need to borrow a corpse to revive the soul. Xie Jingshu noticed that the bowl next to it was filled with human blood. Bai Rui suddenly appeared, wanting to kill these people. Li Mengjue suddenly realized that it was Bai Rui who had been playing tricks in the dark. Bai Rui saw Li Mengjue destroy the medicine she had worked so hard to make to save her lover, and she went mad and chased after Li Mengjue and the others to kill them. However, she was no match for Xie Jingshu and was gravely injured by him.

Bai Rui was unwilling. She didn't expect that after enduring ten years in the Death-Seeking Sect, sacrificing others' great achievements for her own goals, just to resurrect Xue Lang, she would end up being ruined by them here. Xie Jingshu knew that Xue Lang was actually Xue Liangchen, a traitor in Pingzhou. Bai Rui argued that the person in Xie Jingshu's mouth was not Xue Lang at all.

Bai Rui was curious about how Xie Jingshu found her. Xie Jingshu told her that he found Bai Rui based on the paintings on the wall and the scent. Li Mengjue had already suspected that Bai Rui was using the identity of "A Sprig of Artemisia on the Snow" to commit murder, so Xie Jingshu decisively killed Bai Rui. When everyone returned, they discovered that Bai Rui had killed many people and was deeply guilty. Jing Yan realized that Yuan Ji was Liu Shaoqing.
