After Lan Wangji successfully stops the mysterious arm, Wei Wuxian escapes to prevent being spotted by him. He arrives at the nearby Mt. Dafan and meets another young disciple, Jin Ling from the Jin sect. The two have a heated argument which causes Jiang Cheng to come by. Wei Wuxian then learns that Jin Ling is the nephew of Jiang Cheng, whom was left orphaned because of Wei Wuxian's past mistakes. Due to being in Mo Xuanyu's body, Jiang Cheng was unable to recognise Wei Wuxian until the latter starts using his demonic abilities to save everyone from the escaped arm, which summons the Ghost General Wen Ning. While he suspects Wei Wuxian, the latter plays dumb and acts as the notorious cut-sleeve Mo Xuanyu to prevent his cover from being blown. As Lan Wangji also has the same suspicion, he protects Wei Wuxian and even offers to take him back to Gusu when Wei Wuxian speaks of his liking for him, catching Wei Wuxian by surprise. At the end of the episode, the timeline changes to twenty years ago, starting the flashbacks of Wei Wuxian's teenage years.
