Wen Ning successfully saves Jiang Cheng from the Wen sect and brings them and Jiang YanLi to YiLing. Wei WuXian's trust issue is challenged when some Wen sect disciples come to question the sudden commotion. Wen Qing then lies to them and agrees to hide the YunMeng siblings in the YiLing Supervisory Office. In their room, Wen Qing diagnoses Jiang Cheng and finds a worrying issue. Jiang Cheng has lost his Golden Core to Wen ZhuLiu, and the same has happened to their parents before they died. Seeing Jiang Cheng losing control, Wei WuXian is then resolved to find a way to retrieve his Golden Core. He spends many days without food and sleep, worrying both Wen Qing and Jiang YanLi, to the point where Wen Qing also joins to find a cure. Finally, Wei WuXian finds a solution, but this comes with a great price to pay. On the other hand, Wen Chao is determined to find and kill them. (Source: Wikipedia)
