Nie MingJue's flashbacks begin with the time Jin GuangYao is still in the Nie sect as Meng Yao. After overhearing the disciples badmouthing him, Meng Yao retreats to eat alone outside, only to be found by Nie MingJue. As the latter brings him back to meet with the rest of the group, the disciples continue their insults. This angers Nie MingJue and he subsequently appoints Jin GuangYao to be his deputy. The next flashback is when Jin GuangYao murders the general and lies about his intentions. It is revealed that the general had previously witnessed him speaking with someone in private. The next flashback is when Jin GuangYao and Nie MingJue fight in Nightless City. This time, Jin GuangYao threatens Nie MingJue about breaking his sword BaXia to anger him to death. Next, Lan XiChen teaches Jin GuangYao to play "Cleansing" on the guqin for Nie MingJue, but the latter secretly change it a little to worsen Nie MingJue's condition instead. After Nie MingJue and Jin GuangYao argue that night, the former pushes Jin GuangYao down the long stairs. Jin GuangYao then climbs up again and the already angered Nie MingJue now enters the last stage of qi deviation. He starts hallucinating many Jin GuangYao and slashes at the air wildly. Nie HuaiSang soon arrives to try and stop him but he and Jin GuangYao can only watch as Nie MingJue dies. Lastly, in Jin GuangYao's treasure room, he locks Nie MingJue up and instructs Xue Yang to behead him. Paperman Wei WuXian wakes from the memories and swiftly avoids Jin GuangYao's attacks, also using his sword SuiBian to tackle him for a while before successfully returning. As soon as he returns to his body, he and Lan WangJi hurry out to confront Jin GuangYao. They, along with Lan XiChen, tries to enter the treasure room but is also stopped by Su She.
