When Wei WuXian arrives at the inn to wait for Jiang Cheng, he is ambushed by the Wen sect and captured. Wen Chao tortures and throws him into the Burial Mound to die. The overwhelming resentful energy then causes Wei WuXian to succumb to the dark power of the mysterious sword previously found in the XuanWu Cave. Jiang Cheng is unable to find Wei WuXian and decides to regroup with Lan WangJi. The two go to Nightless City to look for answers and learn about Wei WuXian's fate. However, when Lan WangJi is unable to unsheathe Wei WuXian's sword, it gives a bit of hope that the latter is still alive somewhere. They then join Jin ZiXuan and Jiang YanLi at the Unclean Realm that is rightfully taken back from the Wen sect. Lan WangJi and Jiang Cheng then propose to Nie MingJue to start a war against the Wen sect in YiLing. Over at Wen Chao's room, Wang LingJiao is constantly plagued by the fear of Wei WuXian coming back to haunt her. As she decides to run away with their stash of treasure, a mysterious flute sounded near her. (Source: Wikipedia)
