Wei WuXian and Lan WangJi sit on the roof to finally talk after such a long time. Wei WuXian explains that he is not using Xue ChongHai's demonic cultivation, but rather an unusual cultivation that uses music to control things. Lan WangJi then offers to help him and Wei WuXian accepts. The next day, they start their Sunshot Campaign once again. However, due to the overwhelming power of the puppets using the Stygian Iron, the Jiang and Jin sects are unable to defeat them. In the base camp, Jiang Cheng and Jin ZiXuan then discuss about their odds against Wen RuoHan with Nie MingJue. Then, Lan XiChen appears with a battle formation plan for the Nightless City to aid them. While Wei WuXian and Lan WangJi are inspecting the puppets, they are informed that something has happened to Jiang YanLi. Wei WuXian hurries to find her crying because of Jin ZiXuan. He then confronts him and MianMian explains that it was all because Jin ZiXuan has misunderstood Jiang YanLi. However, Wei WuXian attacks Jin ZiXuan and the other Jin disciples in rage, causing Lan WangJi to stop him personally. On the other hand, Lan XiChen keeps a secret about who helped him during the burning of the Cloud Recesses and came up with the battle formation. The battle formation eventually leads the team into the Nightless City and slaughter ensues. While Nie MingJue fights Wen RuoHan, it is revealed that Meng Yao is the person behind this. Seeing that the puppets are increasingly stronger, Wei WuXian retorts to using his cultivation to control them. (Source: Wikipedia)
