With the help of Lan SiZhui and Jin Ling, Wei WuXian prepares porridge for the poisoned disciples. However, as the disciples drink the porridge, they complain about the heavy spice. Just then, they hear the bamboo knocking sound again and Wei WuXian peeks out to investigate. He then tests the other disciples to observe the blind girl outside. While they discover that the blind girl is also mute, she runs away and a mysterious figure comes up to their front door with injuries. Wei WuXian recognises him as Xiao XingChen and brings him inside to cure. However, many puppets suddenly appear and Wei WuXian uses a spell to shut the door. But Song Lan breaks in from the rooftop and starts attacking Wei WuXian. The latter plays his flute to bind him and finds the same kind of black nail in his head. He then instructs someone to play Inquiry, which Lan SiZhui is able to do. They then ask Song Lan three questions, and the last answer causes Xiao XingChen to control Song Lan and attack Wei WuXian again. Xiao XingChen then tells everyone else to leave and Wei WuXian asks Lan SiZhui to lead the disciples. After the two are alone, Xiao XingChen forces Wei WuXian to help him restore a soul, even though the latter is unable to. Wei WuXian then exposes his real identity and Xue Yang finally removes his Xiao XingChen disguise. The two get outside to see Wen Ning and Song Lan fight and Xue Yang wants to take Wei WuXian away. Lan WangJi then arrives in time to save the latter and starts fighting Xue Yang. On the other hand, Song Lan and Wen Ning are also fighting. Left with nothing to do, Wei WuXian then decides to take the disciples to find the blind girl. They finally arrive at a coffin house and finds Xiao XingChen's real body. (Source: Wikipedia)
