Xue Yang is the culprit behind the merciless murder of the YueYang Chang sect, and Xiao XingChen and Song Lan arrive to stop him. However, Wei WuXian and Co. are unable to find the Stygian Iron that Xue Yang has hidden and hence decides to bring him along to QingHe to be punished. Before they part, Wei WuXian asks Xiao XingChen about BaoShan SanRen. In the Unclean Realm, sect leader Nie MingJue welcomes the party and locks Xue Yang up. Additionally, Meng Yao is often seen to be bullied by the Chief General. That night, Lan WangJi leaves for GuSu while he bids goodbye to the oblivious and drunk Wei WuXian sleeping on the roof. The Wen sect attacks the next day to demand for Xue Yang and his piece. When Nie MingJue hurries to find Xue Yang who has escaped, he witnesses Meng Yao murdering the Chief General. While Meng Yao denies and blames Xue Yang on it, he jumps in to save Nie MingJue from a stab. Wen Chao then threatens them that QingHe will undergo the same catastrophe as the Cloud Recesses if they continue to go against them. He ends with another taunt towards Wei WuXian. Later, Nie MingJue decides to execute Meng Yao for his crimes and the latter allows him. However, seeing as Meng Yao saved him earlier, Nie MingJue spares his life and kicks him out of Nie sect instead. (Source: Wikipedia)
